Child PT. presented with swelling in the buccal and palatal maxillary anterior area 2 days ago.. Giant granuloma =central giant cell granuloma

Child PT. presented with swelling in the buccal and palatal maxillary anterior area 2 days ago, the pathology of the lesion there is a giant cell m what is the diagnosis?

A. Giant granuloma =central giant cell granuloma.
B. Hemangioma.

The diagnosis is most likely A. Giant granuloma =central giant cell granuloma.

Here's why:

Giant cell granuloma is a benign tumor characterized by the presence of numerous multinucleated giant cells. It typically presents with a painless, slow-growing swelling in the jaws. Central giant cell granuloma is a specific type that occurs within the bone.
Hemangioma is a benign tumor composed of blood vessels. It usually presents as a red or purple mass, often with a pulsatile quality.

Given the description of the swelling in the buccal and palatal maxillary anterior area, the presence of giant cells, and the absence of other symptoms like pain or bleeding, giant granuloma is the most likely diagnosis. However, a definitive diagnosis would require a biopsy to confirm the presence of giant cells and rule out other possibilities.

It's important to consult with a pediatric dentist or oral pathologist for a proper evaluation and diagnosis. They can provide the appropriate treatment based on the confirmed diagnosis.

Giant Granuloma: A Benign Dental Condition

Giant granuloma is a benign (non-cancerous) oral soft tissue growth. It is characterized by the overgrowth of connective tissue. While the exact cause is unknown, it is often associated with chronic inflammation or irritation.

Symptoms of Giant Granuloma:

Lump or bump: A painless, slow-growing mass in the mouth, often on the gums or in the jawbone.
Bleeding: The mass may bleed easily, especially if it is irritated.
Discomfort: In some cases, the mass can cause discomfort or interfere with eating or speaking.
Diagnosis

A dentist or oral surgeon can diagnose giant granuloma through a physical examination and sometimes a biopsy. A biopsy involves taking a small sample of the tissue for examination under a microscope.

Treatment:

The treatment for giant granuloma depends on its size, location, and the patient's symptoms. Treatment options may include:

Observation: If the granuloma is small and asymptomatic, it may be monitored without treatment.
Surgical excision: The granuloma can be surgically removed. This is often the preferred treatment option, as it can prevent the growth from recurring.
Laser therapy: Laser therapy can be used to destroy the granuloma.
Curettage: This involves scraping away the tissue of the granuloma.

Prevention:

While the exact cause of giant granuloma is unknown, there are some steps that can be taken to reduce the risk of developing this condition:

Maintain good oral hygiene: Brush your teeth twice a day, floss daily, and see your dentist for regular check-ups.
Avoid irritants: Avoid smoking, excessive alcohol consumption, and other irritants that can contribute to oral inflammation.

Giant granuloma is a benign condition that can be effectively treated. If you notice a lump or bump in your mouth, it's important to see a dentist for evaluation.

Step deformity of mandibular body fracture may be due to?

A- Forward pull of lateral pterygoid muscle.
B- Upward pull of masseter and temporalis.
C- Inward pull of medial pterygoid muscle.
D- Downward pull of geniohyoid and mylohyoid.

The most likely cause of a step deformity in a mandibular body fracture is: B. Upward pull of masseter and temporalis muscles

Here's why the other options are less likely:

A. Forward pull of lateral pterygoid muscle:

While the lateral pterygoid muscle can contribute to a slight forward displacement of the mandibular fragment, it wouldn't cause a significant upward step deformity.

C. Inward pull of medial pterygoid muscle:

The medial pterygoid muscle primarily pulls the mandible medially, not upwards. It wouldn't create a step deformity in the body of the mandible.

D. Downward pull of geniohyoid and mylohyoid:

These muscles do pull the mandible downward, but they primarily affect the symphysis and anterior portion of the mandible. They wouldn't cause a step deformity in the body.

The masseter and temporalis muscles are the main elevators of the mandible. When a fracture occurs in the body of the mandible, the unfractured segment pulled by these muscles can move upwards, creating a step deformity with the fractured segment remaining in place.

Additional Points

Here are some additional points to consider:

The direction and severity of the step deformity can vary depending on the location and angle of the fracture, as well as the surrounding muscle tone.
Other factors, such as swelling and hematoma formation, can also contribute to the appearance of a step deformity.
A thorough clinical examination and imaging studies are necessary to accurately diagnose and manage a mandibular body fracture.

The x-ray show scattered radiopaque line in the mandible, the diagnosis will be?

A- Paget disease.
B- Garres syndrome.
C- Fibrous dysplasia.
D- Osteosarcoma..

The most likely diagnosis based on the description of "scattered radiopaque lines in the mandible" is: C- Fibrous dysplasia.

Here's the explanation for each option:

A- Paget disease:

This condition typically shows a "radiolucent" appearance on X-rays, meaning it appears darker than the surrounding bone, which is the opposite of "radiopaque."

B- Garres syndrome:

This is a rare syndrome with several causes, and the X-ray findings are not specific to this condition.

C- Fibrous dysplasia:

This condition can manifest as scattered radiopaque lines in the jawbone, which aligns with the description in the question.

D- Osteosarcoma:

This is a form of bone cancer and typically shows a more aggressive and destructive appearance on X-rays, not just scattered lines.

Therefore, considering the limited information provided, Fibrous dysplasia (option C) is the most likely diagnosis based on the X-ray findings.

It's important to remember that a definitive diagnosis can only be made by a qualified healthcare professional after a thorough examination, including additional tests and consultations as needed.

Anterior open bite caused by?

A. Unilateral condylar fracture.
B. Bilateral condylar fracture.
C. Lefort II.
D. Zygomatic fracture.

Based on the information provided, the most likely cause of an anterior open bite is: B. Bilateral condylar fracture.

Here's why:

- Unilateral condylar fracture:

This can cause an open bite on the side of the fracture, but not necessarily an anterior open bite involving both front teeth.

- Lefort II:

This fracture involves the midface and can cause an open bite, but it typically affects the upper jaw as a whole, not just the front teeth.

- Zygomatic fracture:

This fracture affects the cheekbone and doesn't directly cause an open bite.

- Bilateral condylar fracture:

This fracture affects both condyles, which are the jaw joints located near the front of the ears. When both condyles are fractured, the mandible (lower jaw) can be displaced backward, leading to an anterior open bite where the front teeth don't touch.

However, it's important to note that this is just a general answer based on the information given. Diagnosing the cause of an anterior open bite requires a thorough examination by a qualified healthcare professional, such as a dentist or orthodontist. They will consider various factors, including the patient's history, symptoms, and X-rays, to determine the specific cause and recommend the appropriate treatment.

Ester type of LA secreted by?

A. Liver only.
B. Kidney.
C. Lung.
D. Liver and plasma.

While ester-type local anesthetics (LAs) are primarily metabolized by the liver, the correct answer is not A. Liver only.

Here's a breakdown:

- Ester-type LAs:

Examples include procaine, cocaine, benzocaine, and chloroprocaine.

- Metabolism:

They are hydrolyzed, meaning broken down by water, by an enzyme called pseudocholinesterase, which is present in various tissues throughout the body.

- Main site of metabolism:

While the liver contains high levels of pseudocholinesterase, it is not the only site.

- Other sites:

Significant amounts of pseudocholinesterase are also found in the plasma, making it another contributor to the breakdown of ester-type LAs.

Therefore, the most accurate answer is D. Liver and plasma. Both contribute to the metabolism of ester-type local anesthetics.

Additional Points:

Here are some additional points to remember:

- Individual variations:

Some individuals may have a genetic deficiency in pseudocholinesterase, leading to prolonged effects of ester-type LAs.

- Safety concerns:

Due to potential allergic reactions and the possibility of rapid breakdown due to individual variations in enzyme activity, ester-type LAs are used less frequently than amide-type LAs in clinical settings.

Direct signs for face fracture?

A. Fluid paranasal.

While fluid drainage from the paranasal sinuses can be a symptom of a facial fracture, it's not necessarily a direct sign.

Here's why:

Direct signs of a facial fracture:

- Visible deformity:

This could include anything from a misaligned jawline to bone fragments poking through the skin.

- Tenderness or swelling:

The area around the fracture will likely be tender to the touch and swollen.

- Bruising:

Bruising around the fracture site is common, but not always present.

- Bleeding:

Depending on the location and severity of the fracture, there may be bleeding from the nose, mouth, or ears.

- Loose teeth:

If the fracture involves the jawbone, teeth may become loose or even knocked out.

- Difficulty breathing or speaking:

Fractures affecting the jaw or nasal passages can impede these functions.

Indirect signs of a facial fracture:

- Fluid drainage from the nose or ears:

This can occur if the fracture involves the skull base and damages the lining of the brain or inner ear.

- Severe headache:

This can be a sign of bleeding or swelling inside the skull, which can accompany a facial fracture.

- Numbness or tingling:

This can occur if the fracture damages nerves in the face.

- Changes in vision:

This can be a sign of a fracture involving the bones around the eyes.

Importance of seeking medical attention:

If you suspect a facial fracture, it's crucial to seek medical attention immediately. Early diagnosis and treatment can help prevent complications such as infection, permanent nerve damage, and vision problems.

Additional notes:

Not all facial fractures have all of these signs and symptoms. Some fractures may be very minor and cause no noticeable symptoms.
Facial fractures can be serious, even if they don't seem severe. It's always best to err on the side of caution and get checked out by a doctor.

Cleft lip, cleft palate and missing ear, pragmatism?

A. Acquired defect.
B. Congenital defect.
C. Developments defect.
D. None.

The correct answer is B. Congenital defect.

Here's why:

- Acquired defect:

This refers to a condition that develops after birth, usually due to injury, illness, or exposure to harmful substances. While some conditions can affect the face and ears, the specific combination of cleft lip, cleft palate, and missing ear is highly unlikely to be acquired.

- Congenital defect:

This refers to a condition that is present at birth, meaning it develops during the embryonic or fetal stages. Cleft lip, cleft palate, and missing ear (microtia) are all known to be congenital defects that can occur due to various factors affecting development.

- Developmental defect:

This is a broader term that encompasses both acquired and congenital defects. While technically accurate, it doesn't specify the timing of the defect's origin in this case.

- None:

This is incorrect as the specific combination of these conditions strongly suggests a congenital origin.

Therefore, based on the specific conditions mentioned, B. Congenital defect is the most accurate answer.

It's important to note that pragmatism is not a relevant term in this context and should not be considered when choosing the answer. It refers to a philosophical approach that emphasizes practicality and the use of the most effective means to achieve a goal, which is not applicable to the biological nature of these conditions.

Most difficult to extract?

A. Mand. 3rd molar with mesioangular with fused roots.
B. Mand. 3rd molar with distoangular with divergent curve root.

Determining the most difficult extraction between these two scenarios requires considering several factors:

Mesioangular mandibular third molar with fused roots:

- Challenges:

Fused roots make separation and removal more challenging.
Requires careful technique to avoid root fracture.
May necessitate sectioning the tooth for removal.
Increased risk of damage to adjacent teeth or nerves.

- Advantages:

The mesioangular position generally offers better access compared to distoangular impaction.
Crown may be more visible, facilitating initial access.

Distoangular mandibular third molar with divergent curved root:

- Challenges:

The distoangular position offers limited access and visibility.
Divergent curved root makes instrument placement and leverage more difficult.
Increased risk of bone removal and potential damage to the mandibular canal.
May necessitate extensive bone dissection and flap manipulation.

- Advantages:

Individual root anatomy may sometimes allow for easier separation if the curvature is not severe.
Root may be less likely to be fused compared to mesioangular impaction.

Overall:

While both scenarios present significant challenges, the distoangular mandibular third molar with a divergent curved root is generally considered more difficult to extract due to:

- Limited access and visibility:

The distoangular position significantly hinders the surgeon's ability to visualize and manipulate the tooth.

- Complex root anatomy:

The divergent curved root poses a significant challenge for instrument placement and leverage, increasing the risk of complications.

- Increased risk of bone removal and nerve damage:

Extracting a distoangular tooth often requires more extensive bone removal, which increases the risk of injuring the mandibular canal and associated nerves.

Various Factors:

However, it's important to remember that every case is unique. The difficulty of extraction depends on various factors beyond the angulation and root morphology, such as:

- Patient's anatomy:

Jaw size, bone density, and proximity of vital structures can significantly impact difficulty.

- Surgeon's experience and skill:

A skilled and experienced surgeon can navigate challenging extractions with greater ease.

- Availability of specialized instruments and techniques:

Advanced equipment and techniques can aid in overcoming extraction difficulties.

Therefore, while the distoangular scenario presents greater inherent challenges, the specific difficulty of each case requires a comprehensive evaluation by a qualified dental professional.

Hyperemia results in?

A. Trauma from occlusion.
B. pain of short duration.
C. radiographic changes.
D. all.

The statement "Hyperemia results in all" is partially true, but requires some clarification:

Hyperemia, which is an increased blood flow to a certain tissue, can lead to many consequences, but not necessarily all of the options you listed.

Here's a breakdown:

A. Trauma from occlusion:

While prolonged hyperemia can contribute to tissue damage in some cases, especially if combined with other factors like pressure or infection, it doesn't directly cause trauma through occlusion (blockage).

B. Pain of short duration:

This is also not a guaranteed outcome of hyperemia. While increased blood flow might sometimes cause a tingling or throbbing sensation, pain is not always present, and the duration can vary depending on the cause and severity of hyperemia.

C. Radiographic changes:

This possibility is true. Depending on the type and severity of hyperemia, radiographic imaging (like X-rays, CT scans, or MRIs) might show changes in tissue density or blood flow patterns.

D. All:

As mentioned previously, while hyperemia can lead to various outcomes, it's not guaranteed to cause all of them in every case.

Therefore, the most accurate answer would be:

Hyperemia can result in various outcomes, including changes in tissue appearance, function, and sometimes pain or discomfort. However, it's important to consult a healthcare professional for a proper diagnosis and understanding of the specific effects in your case.

Additionally, remember that different types of hyperemia have different causes and consequences. For example, active hyperemia (increased blood flow due to increased demand) generally has different effects than passive hyperemia (blood flow buildup due to impaired drainage).

Flat bone grows by Endochondral ossification?

A. True.
B. False.

The statement "Flat bone grows by Endochondral ossification" is False.

Flat bones, such as those in the skull, mandible, and clavicle, grow through a process called intramembranous ossification. This process involves the direct conversion of mesenchymal cells (fibroblasts) into bone cells within a membrane, without involving a cartilage intermediate.

In contrast, Endochondral ossification is the process by which long bones grow. It involves the formation of a cartilage model that is gradually replaced by bone tissue. This process is responsible for the lengthening of long bones like the femur, tibia, and humerus.

Here's a table summarizing the key differences:

Feature	Intramembranous Ossification	Endochondral Ossification
Bone Type	Flat bones	Long bones
Precursor Tissue	Mesenchymal tissue	Cartilage
Process	Direct conversion of mesenchymal cells to bone cells	Cartilage model replaced by bone tissue
Function	Primarily for bone width & expansion	Primarily for bone length & growth

Extra oral prosthetic restoration are (extra oral prostheses):

A. Rediumshield
B. Ear plugs for hearing
C. Replace missing eye, missing nose or ear.
D. All.

All of the options mentioned are considered extra oral prosthetic restorations, also known as extra oral prostheses.

Here's a breakdown of each type:

A. Rediumshield:

This is a type of facial shield used to protect the face from harmful substances, such as radiation or chemicals. It typically covers the entire face and head, with openings for the eyes and nose.

B. Ear plugs for hearing:

While not typically considered a restoration, ear plugs can be used to improve hearing in certain situations. For example, musician's earplugs can filter out loud noises while still allowing the wearer to hear music clearly.

C. Replace missing eye, missing nose or ear:

These prostheses are used to restore the appearance and function of facial features that have been lost due to injury, disease, or birth defects. They are custom-made from silicone or other materials to match the patient's individual features as closely as possible.

Overall, extra oral prosthetic restorations offer a valuable solution for people who have lost facial features due to various reasons. They can help improve appearance, restore function, and boost self-confidence.

IN G.V black formula. The instrument of the angle of the blade to the long axis of the handle; (in black three number formula)?

A- First number (blade width)
B- Second No. (blade length)
C- Third No. (blade angle).

the G.V. Black formula uses three numbers to describe dental instruments, and determining the correct answer requires understanding their specific meanings.

Here's a breakdown of each option and why C.

Third No. (blade angle) is the correct answer:

A. First number (blade width):

This is represented by the first number in the formula and indicates the width of the blade in tenths of a millimeter. For example, a "10" in the first position would signify a blade width of 1.0 mm.

B. Second No. (blade length):

This is represented by the second number and indicates the length of the blade in millimeters. For instance, a "5" in the second position would mean a blade length of 5 mm.

C. Third No. (blade angle):

This is indeed the third number and specifies the angle of the blade relative to the long axis of the handle. It's typically measured in clockwise degrees, usually ranging from 40 to 50 degrees. This angle determines the instrument's accessibility and approach to the tooth surface.

Therefore, C. Third No. (blade angle) is the correct answer as it directly indicates the angle of the blade, which is crucial information for identifying and utilizing the instrument effectively.

U-shape radiopaque structure in the upper 1st molar x-ray is?

A. The Zygomatic process.
B. Maxillary sinus wall.

In an upper 1st molar X-ray, the most likely structure to appear as a U-shaped radiopaque structure is:

A. The Zygomatic process of the maxilla.

Here's why:

- Location:

The zygomatic process is a bone projection that arises from the maxilla and forms part of the cheekbone (zygomatic bone). It typically appears superior and slightly anterior to the upper first molar on an X-ray.

- Shape:

The zygomatic process has a characteristic U-shaped or J-shaped appearance on dental radiographs.

- Radiopacity:

Bone appears radiopaque (white) on X-rays compared to softer tissues like muscle or air-filled sinuses.

B. Maxillary sinus wall:

While the maxillary sinus is located near the upper 1st molar, it typically appears as a relatively rounded radiolucency (dark area) on X-rays due to the air it contains. The outline of the sinus wall might be visible, but it wouldn't have the distinct U-shape of the zygomatic process.

Therefore, based on the location, shape, and radiopacity, the U-shaped structure in the upper 1st molar X-ray is most likely the Zygomatic process of the maxilla.

Additional Points:

Here are some additional points to consider:

The specific appearance of the zygomatic process can vary depending on the angle of the X-ray and individual anatomy.
Other structures less likely to be misinterpreted as a U-shape in this context include the coronoid process of the mandible (visible on panoramic X-rays) and the maxillary tuberosity (rounded prominence at the back of the maxilla).

If you have further questions or require a more definitive answer, it's always best to consult a qualified dentist or radiologist for interpretation of specific X-rays.

Radiograph diagnosis of bone destructive lesion in the mandible without evidence of bone formation?

A. Osteomyelitis.
B. Malignancy.
C. Fibro-osseous lesion.
D. Fracture.
E. Osteoradionecrosis.

While all options listed can present with bone destruction in the mandible, the most likely diagnosis for a radiograph showing a destructive lesion without evidence of bone formation in a 29-year-old female is: C. Fibro-osseous lesion.

Here's why:

- Age and gender:

At 29, the patient is within the age range for fibro-osseous lesions, which are more common in young adults and children.

- Bone destruction without bone formation:

This is a characteristic feature of fibro-osseous lesions, particularly central giant cell granuloma (CGG) and cherubism, both of which can present in the mandible.

- Osteomyelitis, malignancy, and fracture:

These conditions typically have additional radiographic features besides just bone destruction, such as periosteal reaction, irregular margins, or evidence of bone trauma in case of fracture.

- Osteoradionecrosis:

This is a less likely possibility in a 29-year-old without a history of radiation therapy to the head and neck region.

However, it's important to note that definitive diagnosis requires a combination of clinical examination, radiographic findings, and possibly further investigations like biopsy.

Listed Options:

Here's a brief overview of the listed options:

A. Osteomyelitis:

Can cause bone destruction, but usually with associated periosteal reaction and sclerosis.

B. Malignancy:

Can present with bone destruction, but often has irregular margins and may show infiltrative patterns.

D. Fracture:

Shows evidence of bone fragments and disruption of normal bone structure.

E. Osteoradionecrosis:

Primarily affects patients with prior radiation therapy, with characteristic features like sequestrum formation and sclerotic bone.

Remember, this information is for general educational purposes and cannot replace professional medical advice. If you have concerns about a specific case, please consult a qualified healthcare professional for proper diagnosis and treatment.

Pt. on ttt with steroid are placed AB. After oral surgical procedures because?

A. The PT. is more susceptible to infection.
B. AB. Are synergistic to steroids.
C. AB. Inhibit herxheimer reaction.
D. AB. Protect the PT. from steroid depletion.

The most likely reason why a patient on long-term steroid therapy (ttt) would receive antibiotics (AB) after oral surgical procedures is: A. The PT. is more susceptible to infection.

Here's why:

Steroids suppress the immune system, making individuals more prone to infections. This is particularly true after surgical procedures, where there is a risk of introducing bacteria into the body.
Oral surgery creates open wounds in the mouth, which are further susceptible to infection due to the presence of bacteria in the oral cavity.
Antibiotics help prevent or fight infections by inhibiting the growth and activity of bacteria. Therefore, they are used prophylactically (preventively) in patients on steroids who undergo oral surgery to minimize the risk of post-operative complications.

Other Options:

While the other options might be relevant in some cases, they are not the most likely reasons for prescribing antibiotics in this scenario:

B. AB are synergistic to steroids:

While some antibiotics can be used in combination with steroids for specific conditions, this is not typically the case for routine oral surgery in patients on long-term steroid therapy.

C. AB inhibit herxheimer reaction:

Herxheimer reactions are associated with certain infections like syphilis and Lyme disease when treated with antibiotics. It's not a common concern after oral surgery.

D. AB protect the PT. from steroid depletion:

This is not a recognized function of antibiotics and doesn't explain their use in this context.

Remember, the specific reason for prescribing antibiotics should always be determined by a healthcare professional based on the individual patient's condition and risk factors.

X-ray Periapical for immature teeth is?

A. Generally conclusive
B. Simply inconclusive
C. Should be compared with contalateral and adjacent tooth.

The answer to this question is C. Should be compared with contalateral and adjacent tooth.

Here's why:

- Immature teeth:

These teeth have incomplete root development and a wide-open apical foramen. This anatomical variation can make interpreting periapical X-rays challenging.

- Periapical radiographs:

These X-rays focus on the root apices and surrounding bone. For mature teeth, they can effectively show periapical lesions and inflammation.

- Challenges with immature teeth:

In immature teeth, the open apex can mimic a periapical radiolucency, making it difficult to definitively diagnose pathology. Additionally, the developing bone around the roots may appear irregular, further complicating interpretation.

To overcome these challenges, dentists compare the periapical X-ray of the immature tooth with its contralateral tooth (the same tooth on the opposite side of the mouth) and adjacent teeth. These comparison radiographs provide a baseline for the normal appearance of the developing bone and allow for better differentiation between normal anatomy and possible pathology.

Therefore, while periapical X-rays for immature teeth can provide valuable information, comparing them with other radiographs is crucial for a more accurate diagnosis.

Radiographic diagnosis of the bilateral expansile radiopaque area in the canines-premolars region of the mandible is?

A. Hematoma
B. Remaining root
C. Torus mandibularis
D. Internal oblique ridge
E. Genial tubercle.

Based on the description, the most likely radiographic diagnosis for the bilateral expansile radiopaque area in the canines-premolars region of the mandible is: C. Torus mandibularis.

Here's why:

- Torus mandibularis:

This is a common benign bony outgrowth that typically appears bilaterally on the lingual surface of the mandible, in the canine and premolar areas. It often has a smooth, rounded, or lobulated appearance, aligning with the description of an "expansile radiopaque area."

- Location:

The location mentioned, namely the canines-premolars region of the mandible, is a typical location for torus mandibularis.

- Bilateral:

Torus mandibularis usually presents bilaterally, as noted in the question.

- Other options:

The other options are less likely due to their characteristics:

Hematoma: A hematoma (blood clot) would not typically appear bilaterally and would not typically have a well-defined, "expansile" shape.
Remaining root: A remaining root would likely appear more localized and defined as a single radiopaque structure, not bilateral and "expansile."
Internal oblique ridge: This is a natural anatomical feature of the mandible and wouldn't be considered an abnormal finding.
Genial tubercle: The genial tubercle is located more anteriorly on the midline of the mandible, not in the canine-premolar region.

Therefore, based on the provided information, torus mandibularis is the most probable diagnosis for the described radiographic findings.

However, it's important to note that a conclusive diagnosis can only be made by a qualified healthcare professional after a thorough clinical examination and review of all relevant imaging studies.

Pt. with radiopacity in the Periapical area of 1st mandibular molar with wide carious lesion and bad periodontal condition is?

A. Condensing osteitis
B. Hypercementosis.

Based on the provided information, the most likely diagnosis is: B. Hypercementosis.

Here's why:

- Radiopacity in the periapical area:

This is a characteristic feature of hypercementosis, where excess cementum builds up around the tooth root, appearing radiopaque on an X-ray.

- Wide carious lesion:

While condensing osteitis can also occur with caries, the presence of a large, ongoing carious lesion is more suggestive of hypercementosis as a reactive response to the inflammation and irritation caused by the caries.

- Bad periodontal condition:

Hypercementosis can be associated with chronic periodontal inflammation, which aligns with the description of the patient's condition.

While condensing osteitis can also present with some of these features, the presence of a large active carious lesion makes it less likely. Condensing osteitis is usually a localized reaction to a chronic, low-grade inflammatory process, not a large, active carious lesion.

However, it's important to remember that definitive diagnosis requires a comprehensive clinical examination and interpretation of all available information, including additional X-rays or other imaging modalities. Consulting a dental professional is crucial for accurate diagnosis and treatment planning.

Last sensation disappears after LA?

A. Pain
B. Deep pressure.
C. Temperature.

The answer to the riddle is C. Temperature.

Here's the reasoning:

- Pain:

While pain can indeed fade away at the end of life, it doesn't necessarily disappear as the last sensation.

- Deep pressure:

The ability to sense deep pressure often remains until after other senses decline.

- Temperature:

The perception of temperature is one of the first senses to lose sensitivity, and often disappears before other sensations like pain or touch.

Therefore, according to the riddle's prompt of "last sensation disappearing after LA," the most likely answer is temperature.

However, it's important to note that the timing and order of sensory loss can vary significantly depending on the individual and the cause of death.

Endocrine and exocrine glands are?

A. Pancreas.
B. Pituitary gland.

the correct answer is: A. Pancreas

While both the pancreas and pituitary gland are indeed glands, they each fall into different categories based on their secretion method:

- Endocrine glands:

These glands secrete hormones directly into the bloodstream. The pituitary gland is a classic example, releasing hormones that regulate numerous bodily functions like growth, metabolism, and reproduction.

- Exocrine glands:

These glands secrete products (enzymes, mucus, sweat, etc.) through ducts onto the body's surfaces or into cavities. The pancreas plays a dual role here. It functions as an endocrine gland by releasing insulin and glucagon into the bloodstream to regulate blood sugar. However, it also has an exocrine function, secreting digestive enzymes into the pancreatic duct that empty into the duodenum to aid digestion.

Therefore, in terms of being both endocrine and exocrine, the correct answer is: A. Pancreas
