    Patients with aggressive periodontitis and other forms of perio (other than mild to moderate chronic periodontitis) should be . . .

    • Referred to a periodontist

    • Treated at the general dentist

    • Referred to an endodontist

    • Told to come in once per month

    Correct Answer
    A. Referred to a periodontist
    Explanation
    Patients with aggressive periodontitis and other forms of perio require specialized treatment and management. A periodontist is a dental specialist who has advanced training in diagnosing and treating gum diseases, including aggressive periodontitis. They have expertise in performing surgical procedures, such as gum grafts and pocket reduction surgery, which may be necessary for these patients. Referring these patients to a periodontist ensures that they receive the specialized care and interventions needed to effectively manage their condition.

    A patient complains of soreness in the jaw on waking in the morning. She is having stressful problems at work. She complains that some of her lower teeth are "wearing down". Which one of the following conditions does this patient most likely have?

    • Fractured Jaw

    • Parafunctional habit

    • Severe periodontitis

    • NUG

    Correct Answer
    A. Parafunctional habit
    Explanation
    The patient most likely has a parafunctional habit. Parafunctional habits are repetitive movements or actions of the jaw that are not related to normal functions such as eating or speaking. These habits, often caused by stress or anxiety, can lead to soreness in the jaw and wearing down of the teeth. In this case, the patient's stressful problems at work suggest that she may be clenching or grinding her teeth during sleep, leading to the symptoms described.

  • 4. 

    In health, the gingiva is pink in color. Red tissue is a change that may be seen in disease.

    • Both statements are true

    • Both statements are false

    • The first statement is true, the second statement is false

    • The first statement is false, the second statement is true

    Correct Answer
    A. Both statements are true
    Explanation
    The first statement is true because in a healthy state, the gingiva (gums) are typically pink in color. The second statement is also true because red tissue in the gingiva can indicate the presence of disease or inflammation.

    Rate this question:

  • 5. 

    Which characteristics are that of a suprabony pocket?

    • Base of pocket is at the alveolar crest

    • Base of pocket is coronal to alveolar crest

    • Base of pocket is apical to alveolar crest

    • Base of pocket is at the CEJ

    Correct Answer
    A. Base of pocket is coronal to alveolar crest
    Explanation
    A suprabony pocket is characterized by the base of the pocket being coronal to the alveolar crest. This means that the bottom of the pocket is located above the level of the alveolar crest, which is the bony ridge that surrounds and supports the teeth. This condition is typically associated with periodontal disease, where the gum tissue pulls away from the tooth, forming a pocket. The pocket depth is measured from the gingival margin to the base of the pocket, and in the case of a suprabony pocket, this measurement would be above the level of the alveolar crest.

    Rate this question:

  • 6. 

    Which one of the following conditions is best treated with a night guard?

    • Tooth with severe bone loss

    • Tongue-thrusting habit

    • Teeth with severe abrasion

    • Clenching and grinding

    Correct Answer
    A. Clenching and grinding
    Explanation
    Clenching and grinding is best treated with a night guard because it helps to protect the teeth from the excessive forces and pressure caused by these habits. A night guard acts as a cushion and prevents the teeth from grinding against each other, reducing the risk of tooth damage, tooth wear, and jaw pain. It also helps to relax the jaw muscles and alleviate symptoms associated with clenching and grinding, such as headaches and facial pain.

    Rate this question:

  • 7. 

    Which one of the following healing responses is seen in gingivitis after periodontal debridement?

    • Formation of new bone, cementum, and periodontal ligament

    • Formation of new cementum and PDL

    • Reduction of inflammation

    • Reattachment of the alveolar mucosa

    Correct Answer
    A. Reduction of inflammation
    Explanation
    After periodontal debridement, the healing response seen in gingivitis is the reduction of inflammation. Periodontal debridement involves the removal of plaque and tartar from the teeth and gums, which helps to reduce the inflammation in the gingival tissues. This process allows the gums to heal and become healthier, leading to a reduction in inflammation. The other options mentioned, such as the formation of new bone, cementum, and periodontal ligament, formation of new cementum and PDL, and reattachment of the alveolar mucosa, are not typically seen in the healing response of gingivitis after periodontal debridement.

    Which one of the following radiographic structures is described as a thin radiopaque line surrounding the entire root and is continuous with the alveolar crest?

    • Dentin

    • Cementum

    • Lamina dura

    • PDL fibers

    • Gingival fibers

    Correct Answer
    A. Lamina dura
    Explanation
    The correct answer is lamina dura. Lamina dura is a thin radiopaque line that surrounds the entire root of a tooth and is continuous with the alveolar crest. It represents the compact bone that lines the tooth socket and provides support to the tooth.

  • 9. 

    When complete removal of debris is not possible with non-surgical removal, _________ surgery may be indicated.

    • Bone graft

    • Flap

    • Implant

    • Plaque removal

    Correct Answer
    A. Flap
    Explanation
    When complete removal of debris is not possible with non-surgical removal, flap surgery may be indicated. Flap surgery involves lifting a section of tissue to gain access to the underlying area for cleaning and removal of debris. This procedure allows for better visibility and access to thoroughly clean the affected area, making it an appropriate choice when non-surgical methods are insufficient.

    Rate this question:

  • 10. 

    Which one of the following periodontal changes can be seen on radiographs?

    • Gingival recession

    • Periodontal pockets

    • Furcation involvement

    • Tooth mobility

    Correct Answer
    A. Furcation involvement
    Explanation
    Furcation involvement refers to the loss of bone and tissue support around the roots of multi-rooted teeth, leading to the exposure of furcation areas. This condition can be seen on radiographs as a darkened area between the roots of the affected tooth. Radiographs are useful in identifying furcation involvement and determining its severity, which helps in planning appropriate treatment strategies for periodontal disease.

    Rate this question:

  • 11. 

    The position of the gingival margin is apical to the CEJ when it . . .

    • Covers more of the crown of the tooth than it would in health

    • Covers less of the tooth than is normal in health

    Correct Answer
    A. Covers less of the tooth than is normal in health
    Explanation
    When the gingival margin covers less of the tooth than is normal in health, it means that the gum tissue has receded or pulled away from the tooth. This can be caused by factors such as gum disease, aggressive brushing, or aging. As a result, more of the tooth's root surface becomes exposed, which can lead to tooth sensitivity and an increased risk of dental decay.

    Rate this question:

  • 12. 

    Which of the following helps determine success after periodontal debridement (reevaluation)?

    • Amount of time spent on the procedure

    • Number of quadrants completed

    • Total removal of calculus

    • Tissue response

    Correct Answer
    A. Tissue response
    Explanation
    Tissue response helps determine success after periodontal debridement (reevaluation). This is because the goal of periodontal debridement is to remove calculus and bacteria from the teeth and gums, and the success of this procedure is reflected in the response of the surrounding tissues. If the tissues show signs of healing, such as reduced inflammation and improved attachment, it indicates that the debridement was effective. Therefore, tissue response is an important factor in determining the success of periodontal debridement.

    Rate this question:

  • 13. 

    Occlusal trauma in combination with chronic inflammatory periodontitis may result in greater tooth mobility and alveolar bone loss because occlusal trauma causes periodontal pocket formation.

    • Both the statement and the reason are correct but not related

    • The statement is correct, but the reason is not

    • The statement is not correct, but the reason is correct

    • Neither the statement nor the reason is correct

    Correct Answer
    A. The statement is correct, but the reason is not
    Explanation
    The statement is correct because occlusal trauma in combination with chronic inflammatory periodontitis can indeed lead to increased tooth mobility and alveolar bone loss. However, the reason is not correct because occlusal trauma does not directly cause periodontal pocket formation. Periodontal pocket formation is primarily caused by the inflammatory response to bacterial plaque and calculus accumulation in the periodontal tissues.

  • 14. 

    A patient has returned for a 2-week follow-up visit after periodontal surgery complaining of tooth mobility. There was no mobility before the surgery was done. Which one of the following should be explained to the patient?

    • Teeth must be splinted immediately

    • Mobility will decrease in time

    • Additional surgery will be needed

    • Systemic antibiotics are indicated

    Correct Answer
    A. Mobility will decrease in time
    Explanation
    After periodontal surgery, it is common for patients to experience temporary tooth mobility. This is due to the healing process and the adjustment of the surrounding tissues. As the tissues heal and stabilize, the tooth mobility will decrease over time. Therefore, it is important to reassure the patient that this is a normal part of the healing process and that the mobility will improve with time.

    ___________ instruments are the ideal shape to adapt to root surfaces

    • Curette

    • Ultrasonic

    • Sickle

    • Curved

    Correct Answer
    A. Curette
    Explanation
    Curettes are the ideal shape to adapt to root surfaces because they have a curved and rounded design that allows for better access and adaptation to the irregularities and contours of the root surface. This shape helps in effectively removing plaque, calculus, and debris from the root surface during dental procedures, promoting better oral hygiene and preventing further damage or infection. The curved shape of a curette also allows for better control and precision during the cleaning process.

    Rate this question:

  • 16. 

    The normal crest of interproximal bone is located at a level

    • 2.0 mm apical to the CEJ

    • 3.0 mm coronal to the CEJ

    • 2-3 mm coronal to the cusp tip of the crown

    • 3.5 mm apical to the cusp tip of the crown

    Correct Answer
    A. 2.0 mm apical to the CEJ
    Explanation
    The normal crest of interproximal bone is located 2.0 mm apical to the CEJ (cementoenamel junction). This means that the crest of the bone, which supports the teeth, is positioned 2.0 mm below the point where the enamel of the tooth meets the cementum. This is an important anatomical landmark for dental professionals to assess the health and stability of the surrounding bone.

    Rate this question:

  • 17. 

    Which one of the following definitions pertains to primary occlusal trauma?

    • Normal Occlusal force with adequate bone support

    • Excessive occlusal force with adequate bone support

    • Normal occlusal force with reduced bone support

    • Excessive occlusal force with reduced bone support

    Correct Answer
    A. Excessive occlusal force with adequate bone support
    Explanation
    Primary occlusal trauma refers to excessive occlusal force, meaning that there is more force being applied to the teeth and supporting structures than they can tolerate. However, in primary occlusal trauma, the bone support is still adequate, meaning that the bone surrounding the teeth is healthy and able to withstand the excessive force. This is different from secondary occlusal trauma, where the occlusal force is normal, but the bone support is reduced.

    Rate this question:

  • 18. 

    Arteries that supply blood and lymphatics to the free gingiva originate from all of the following parts of the periodontium except one. Which one is the exception?

    • Supraperiosteal

    • PDL

    • Alveolar bone

    • Cementum

    Correct Answer
    A. Cementum
    Explanation
    The arteries that supply blood and lymphatics to the free gingiva originate from all parts of the periodontium except the cementum. The cementum is a hard tissue that covers the root surface of the tooth, and it does not have direct blood vessels or lymphatics. The blood supply to the free gingiva mainly comes from the supraperiosteal arteries, which are located in the connective tissue just beneath the gingiva. The periodontal ligament (PDL) and alveolar bone also contribute to the blood supply of the free gingiva.

    Localized rinses are not as effective because they do not get into the pocket, need to irrigate

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Localized rinses are not as effective because they do not get into the pocket and need to irrigate. This suggests that localized rinses, which are designed to target specific areas, may not be able to reach deep enough into the pocket to effectively clean and treat the area. Therefore, irrigation, which involves flushing the area with a solution, may be necessary to ensure thorough cleaning and treatment.

    Rate this question:

  • 20. 

    ___________ instruments are beneficial for plaque and deposit removal, with lavage.

    • Metal

    • Curette

    • Ultrasonic

    • Pointed

    Correct Answer
    A. Ultrasonic
    Explanation
    Ultrasonic instruments are beneficial for plaque and deposit removal, with lavage. Ultrasonic instruments use high-frequency sound waves to create vibrations that help break up and remove plaque and deposits from teeth and gums. These instruments also have a built-in water irrigation system, which helps flush out debris and keep the area clean during the procedure. This makes ultrasonic instruments an effective and efficient tool for dental professionals in maintaining oral hygiene.

    Which of the following limits the effectiveness of nonsurgical periodontal debridement procedures? (POTENTIAL BOARDS QUESTION)

    • Old instruments

    • Too sharp instruments

    • Too dull instruments

    • Poor quality/cheap instruments

    Correct Answer
    A. Too dull instruments
    Explanation
    Too dull instruments limit the effectiveness of nonsurgical periodontal debridement procedures because they are unable to effectively remove plaque and calculus from the teeth and gums. Dull instruments do not have sharp edges, which are necessary to efficiently scrape off the buildup of bacteria and debris. As a result, the procedure may not be thorough, leading to incomplete cleaning and ineffective treatment of periodontal disease.

    Rate this question:

  • 22. 

    Which of the following is one of the 3 ways to treat a pocket? (Non-surgical)

    • Mechanical, brush and floss

    • Scaling and root planing

    • Chemotherapeutic agents

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    All of the options mentioned (mechanical, brush and floss; scaling and root planing; chemotherapeutic agents) are non-surgical ways to treat a pocket. Mechanical methods such as brushing and flossing help remove plaque and bacteria from the pocket. Scaling and root planing involve deep cleaning of the tooth and root surfaces to remove tartar and smooth the root surface. Chemotherapeutic agents, such as antimicrobial mouth rinses or gels, can be used to kill bacteria and reduce inflammation in the pocket. Therefore, all of the above options are valid ways to treat a pocket non-surgically.

    Which one of the following features does the computed tomographic process provide?

    • A three-dimensional view of the area of interest

    • A two dimensional view of the area of interest

    • A global view of all oral structures

    • A close-up view of the periapical structures

    Correct Answer
    A. A three-dimensional view of the area of interest
    Explanation
    The computed tomographic process provides a three-dimensional view of the area of interest. This means that it can provide a detailed and comprehensive view of the structures within the area being examined, allowing for a better understanding of their spatial relationships and potential abnormalities. This is in contrast to a two-dimensional view, which would only provide a flat representation of the area.

    Rate this question:

  • 24. 

    Which of the following best measures the severity of periodontal disease in a population?

    • Radiographs

    • Intraoral cameras

    • Indices

    • Surgical costs

    Correct Answer
    A. Indices
    Explanation
    Indices are the best measure of the severity of periodontal disease in a population. Indices are standardized tools used by dental professionals to assess and quantify the extent and severity of periodontal disease. They provide a systematic and objective way to measure parameters such as gingival inflammation, plaque accumulation, and periodontal pocket depth. By using indices, dental professionals can accurately evaluate the severity of periodontal disease in a population and track its progression over time.

    Rate this question:

  • 25. 

    The position of the gingival margin often changes in disease. The shape of a papilla rarely changes due to disease.

    • Both statements are true

    • Both statements are false

    • The first statement is true, the second statement is false

    • The first statement is false, the second statement is true

    Correct Answer
    A. The first statement is true, the second statement is false
    Explanation
    The first statement is true because the position of the gingival margin can indeed change in disease. Gingival margin refers to the edge of the gum tissue that surrounds the teeth, and it can shift or recede in conditions like periodontitis or gingivitis. However, the second statement is false because the shape of a papilla, which is the triangular gum tissue between adjacent teeth, can also change due to disease. Inflammation or infection can cause the papilla to become swollen, distorted, or even disappear.

    Rate this question:

  • 26. 

    In health, the interdental papilla is pointed. In disease, the interdental papilla might be missing.

    • Both statements are true.

    • Both statements are false.

    • The first statement is true, the second statement is false

    • The first statement is false, the second statement is true

    Correct Answer
    A. Both statements are true.
    Explanation
    The interdental papilla refers to the triangular gum tissue between adjacent teeth. In a healthy condition, the interdental papilla is pointed, meaning it fills the space between the teeth completely. However, in certain diseases or conditions such as periodontal disease, the interdental papilla might be missing or become significantly reduced in size. Therefore, both statements are true as they describe the appearance of the interdental papilla in different health conditions.

    Which one of the following structures is involved in the attachment of gingiva to the tooth surface?

    • Alveolar mucosa

    • Dentogingival unit

    • Mucogingival unit

    • Desmosomes

    Correct Answer
    A. Dentogingival unit
    Explanation
    The dentogingival unit is involved in the attachment of the gingiva to the tooth surface. It refers to the anatomical structures that connect the tooth to the gingiva, including the junctional epithelium, connective tissue fibers, and the gingival fibers. These structures help to maintain the stability and integrity of the gingiva around the tooth.

    Guided Tissue regeneration (GTR) focuses on the isolation or exclusion of what type of tissue cells?

    • Junctional epithelial and gingival connective tissue

    • Alveolar bone and sulcular epithelium

    • Connective tissue and alveolar bone

    • Alveolar bone and junctional epithelial

    Correct Answer
    A. Junctional epithelial and gingival connective tissue
    Explanation
    GTR focuses on the isolation or exclusion of junctional epithelial and gingival connective tissue. This technique aims to create a barrier that prevents the migration of these specific tissue cells, allowing for the regeneration of other tissues such as alveolar bone and sulcular epithelium. By excluding junctional epithelial and gingival connective tissue, GTR promotes the growth of desired tissues and facilitates the regeneration process.

    • Both statements are true

    • Both statements are false

    • The first statement is true, the second statement is false

    • The first statement is false, the second statement is true.

    Correct Answer
    A. The first statement is true, the second statement is false
    Explanation
    The first statement is true because in a healthy state, the tissue should fit tightly around the tooth. However, the second statement is false because in a healthy state, the margin should be coronal or at the same level as the cementoenamel junction (CEJ), not apical to it.

    Rate this question:

  • 30. 

    All of the following parts of the periodontium are affected by occlusal trauma except one. Which one Is the exception?

    • Periodontal ligament

    • Alveolar Bone

    • Gingiva

    • Cementum

    Correct Answer
    A. Gingiva
    Explanation
    Occlusal trauma refers to excessive forces applied to the teeth during biting and chewing. These forces can cause damage to the periodontium, which includes the periodontal ligament, alveolar bone, gingiva, and cementum. However, the exception in this case is the gingiva. While occlusal trauma can cause damage to the other parts of the periodontium, it typically does not directly affect the gingiva. The gingiva is more commonly affected by factors such as poor oral hygiene, inflammation, and periodontal diseases.

    Rate this question:

  • 31. 

    Which one of the following healing responses is seen in periodontitis after periodontal debridement

    • Reattachment of the sulcular epithelium

    • Reattachment of desmosomes

    • Formation of new bone, cementum, and PDL

    • Repair with a long junctional epithelium

    Correct Answer
    A. Repair with a long junctional epithelium
    Explanation
    After periodontal debridement, the healing response seen in periodontitis is repair with a long junctional epithelium. This occurs when the epithelial cells migrate along the root surface and form a new attachment, but it is not as strong or functional as the original attachment. This healing response helps to stabilize the periodontal tissues and prevent further progression of the disease.

    Rate this question:

  • 32. 

    Which one of the following benefits is seen after subgingival debridement?

    • Disruption of gram-negative microbial flora

    • Repopulation of gram-negative anaerobic flora

    • Removal of gram-positive facultative flora

    • Interference with attachment of gram-positive anaerobic flora to root surfaces

    Correct Answer
    A. Disruption of gram-negative microbial flora
    Explanation
    Subgingival debridement refers to the removal of plaque and calculus from below the gum line. This procedure helps disrupt the gram-negative microbial flora, which is associated with periodontal disease. By removing the harmful bacteria, subgingival debridement promotes a healthier oral environment and reduces the risk of further gum inflammation and damage.

    If we refer a patient to a periodontist, why must we still see them too?

    • We need to make sure the periodontist is doing their job

    • We need the money so we need to reschedule appointments

    • Periodontists don't check for cavities

    • Once referred to a periodontist, the patient does not need to come back to us

    Correct Answer
    A. Periodontists don't check for cavities
    Explanation
    Referring a patient to a periodontist does not eliminate the need for the patient to continue seeing their regular dentist. While periodontists specialize in treating gum diseases and other issues related to the gums and supporting structures of the teeth, they do not typically check for cavities. Regular dentists are responsible for monitoring overall oral health, including checking for cavities and addressing other dental concerns. Therefore, even if a patient is referred to a periodontist, they still need to see their regular dentist for comprehensive dental care.

    Rate this question:

  • 34. 

    Which characteristics are that of a gingival pocket (pseudo-pocket)/normal sulcus?

    • Base of pocket is at the alveolar crest

    • Base of pocket is at the CEJ

    • Base of pocket is coronal to the alveolar crest

    • Base of pocket is apical to alveolar crest

    Correct Answer
    A. Base of pocket is at the CEJ
    Explanation
    A gingival pocket (pseudo-pocket)/normal sulcus is characterized by the base of the pocket being at the CEJ (cementoenamel junction). This means that the pocket does not extend beyond the level of the CEJ and is confined within the gingival tissue. This is in contrast to a true periodontal pocket, where the base of the pocket is apical to the alveolar crest.

    • Maxillary lateral incisors

    • Maxillary second molars

    Correct Answer
    A. Maxillary lateral incisors
    Explanation
    The width of attached gingiva refers to the amount of gum tissue that is firmly attached to the underlying bone. In general, the width of attached gingiva is greatest in the anterior region of the mouth, particularly around the incisors. Therefore, the correct answer is maxillary lateral incisors.

    What is the purpose of a gingival curettage?

    • To remove granulation tissue

    • To remove plaque

    • To remove cementum to make a smooth surface

    • To reduce inflammation in the tissue

    Correct Answer
    A. To remove granulation tissue
    Explanation
    Gingival curettage is a dental procedure performed to remove granulation tissue, which is a type of tissue that forms as a result of chronic inflammation. This tissue can hinder the healing process and contribute to further inflammation and infection. By removing the granulation tissue, the dentist aims to promote proper healing and reduce inflammation in the gum tissue. This procedure is often recommended for patients with periodontal disease or other gum-related issues.

    Which of the following limits the effectiveness of nonsurgical periodontal debridement procedures? (POTENTIAL BOARDS QUESTION)

    • Probing depths greater than 5 mm

    • Probing depths greater than 2 mm

    • Probing depths greater than 6 mm

    • Probing depths greater than 7 mm

    Correct Answer
    A. Probing depths greater than 5 mm
    Explanation
    Probing depths greater than 5 mm limit the effectiveness of nonsurgical periodontal debridement procedures because it indicates the presence of deep periodontal pockets. These deep pockets are difficult to clean thoroughly with nonsurgical techniques, such as scaling and root planing. Deeper pockets provide a favorable environment for bacteria to thrive and can lead to continued inflammation and disease progression. Therefore, addressing these deep pockets may require surgical interventions or additional treatments to achieve optimal periodontal health.

    • Enamel

    • Cementum

    • Junctional epithelium

    • Lamina propria

    Correct Answer
    A. Lamina propria
    Explanation
    The correct answer is lamina propria. The lamina propria is a layer of connective tissue found in mucous membranes, such as those lining the digestive tract. It contains blood vessels, lymphatic vessels, and immune cells, making it vascular. Enamel, cementum, and junctional epithelium are all avascular structures.

    After non-surgical periodontal therapy, the greatest amount of healing takes place within-

    • 3-6 months

    • 3-6 days

    • 3-6 weeks

    • 24 hours

    Correct Answer
    A. 3-6 weeks
    Explanation
    After non-surgical periodontal therapy, the greatest amount of healing takes place within 3-6 weeks. This is because it takes time for the gums and surrounding tissues to recover and regenerate after the therapy. The initial inflammation and swelling subside, and the gums start to reattach to the teeth, reducing pocket depths and improving overall gum health. It is important to wait for this healing period to ensure the success of the therapy and maintain good oral hygiene practices during this time.

    Cells coming from which one of the following structures is required for successful periodontal regeneration?

    • PDL

    • Alveolar Bone

    • Gingival Connective tissue

    • Gingival epithelium

    Correct Answer
    A. PDL
    Explanation
    The periodontal ligament (PDL) is required for successful periodontal regeneration. The PDL is a specialized connective tissue that connects the tooth root to the alveolar bone. It contains various cell types, including fibroblasts, cementoblasts, and osteoblasts, which are essential for the regeneration of periodontal tissues. These cells play a crucial role in the formation of new periodontal ligament fibers, cementum, and alveolar bone, which are necessary for the successful regeneration of the periodontium.

    Which of the following is a potential issue with tetracycline?

    • Causes permanent discoloration adult teeth

    • Causes permanent discoloration in fetus teeth

    • Causes permanent discoloration in adult of fetus teeth

    • Softens enamel

    Correct Answer
    A. Causes permanent discoloration in fetus teeth
    Explanation
    Tetracycline is known to cause permanent discoloration in the teeth of a fetus. This occurs when the medication is taken by a pregnant woman during the second half of her pregnancy. Tetracycline can cross the placenta and accumulate in the developing teeth of the fetus, leading to a yellow or gray-brown discoloration that is permanent and cannot be reversed. It is important for pregnant women to avoid taking tetracycline to prevent this potential issue.

    The radiographic evaluation of alveolar bone loss associated with periodontitis is based on the status of which one of the following structures?

    • Interdental septum

    • CEJ

    • Periapical Bone

    • PDL fibers

    Correct Answer
    A. Interdental septum
    Explanation
    The radiographic evaluation of alveolar bone loss associated with periodontitis is based on the status of the interdental septum. The interdental septum is the bone between the teeth, and its condition can indicate the presence and extent of bone loss caused by periodontitis. By assessing the interdental septum on radiographs, dentists can determine the severity of the disease and plan appropriate treatment.

    All of the following are reasons for using radiographs in periodontics except one. Which one is the exception?

    • Identify predisposing factors

    • Detect early to moderate bone changes

    • Determine the shape and depth of perio pockets

    • Serve as baseline data and as a means of evaluating posttreatment results

    Correct Answer
    A. Determine the shape and depth of perio pockets
    Explanation
    Radiographs are commonly used in periodontics for various reasons. They help identify predisposing factors that may contribute to periodontal disease. They also aid in detecting early to moderate bone changes, which can be crucial in diagnosing and monitoring periodontal disease progression. Additionally, radiographs serve as baseline data and allow for the evaluation of posttreatment results. However, determining the shape and depth of periodontal pockets is not a primary purpose of radiographs in periodontics. This information is typically obtained through clinical measurements using a periodontal probe.
