In an adult patient with chronic adult periodontitis the most successful approach to treatment is:?
- A.
Surgery
- B.
Extreme initial treatment followed by reviews every year
- C.
Initial periodontal therapy followed by maintenance therapy alone
Correct Answer
C. Initial periodontal therapy followed by maintenance therapy aloneExplanation
The most successful approach to treatment for an adult patient with chronic adult periodontitis is initial periodontal therapy followed by maintenance therapy alone. This approach involves an initial deep cleaning and scaling of the teeth and gums to remove plaque and tartar buildup. After this initial treatment, regular maintenance therapy, including professional cleanings and proper oral hygiene practices, is crucial to prevent further progression of the disease and maintain the health of the gums and teeth. Surgery may be necessary in some cases, but it is not the most successful approach for all patients.Rate this question:

Adult patient present clinically with irregular thickness of buccal gingiva, a round diamond bur used to correct and establish a physiological gingival contour. The type of this procedure is/are:?
- A.
Gingivectomy.
- B.
Combined gingivoplasty & gingivectomy.
- C.
None of the above.
- D.
Gingivoplasty.
Correct Answer
D. Gingivoplasty.Explanation
The correct answer is Gingivoplasty. Gingivoplasty is a surgical procedure performed to reshape and contour the gingiva. In this case, the irregular thickness of the buccal gingiva is being corrected using a round diamond bur, which is a common tool used in gingivoplasty procedures. Gingivectomy, on the other hand, involves the removal of gum tissue, and combined gingivoplasty and gingivectomy refers to a combination of both procedures. None of these options accurately describe the procedure being performed in this scenario.Rate this question:

Which of the following does not come under phase 1 therapy?
- A.
Plaque control
- B.
Root planning
- C.
Restoration
- D.
Removable prosthodontic appliances
Correct Answer
D. Removable prosthodontic appliancesExplanation
Removable prosthodontic appliances do not come under phase 1 therapy because phase 1 therapy primarily focuses on the initial treatment of periodontal disease. Plaque control, root planning, and restoration are all part of phase 1 therapy as they involve the removal of plaque and calculus, restoration of damaged teeth, and establishment of proper oral hygiene practices. Removable prosthodontic appliances, on the other hand, are prosthetic devices used to replace missing teeth and are typically considered part of phase 2 or 3 therapy.Rate this question:

The concept of one stage Full mouth disinfection has been put forth to prevent?
- A.
Adhesion of microorganisms
- B.
Proliferation of microorganisms
- C.
Bacterial invasion
- D.
Translocation of microorganisms
Correct Answer
D. Translocation of microorganismsExplanation
The concept of one stage Full mouth disinfection aims to prevent the translocation of microorganisms. This means that by disinfecting the entire mouth in one stage, the spread of microorganisms from one area to another can be minimized or eliminated. This is important because the translocation of microorganisms can lead to the colonization of new areas and the development of infections or diseases. By preventing translocation, the risk of further complications can be reduced, promoting better oral health.Rate this question:

Main aim of restoration of carious lesion in phase-I therapy?
- A.
To restore function of tooth
- B.
To restore form of tooth
- C.
All of the above
- D.
To reduce microbial source
Correct Answer
D. To reduce microbial sourceExplanation
The main aim of restoration of carious lesions in phase-I therapy is to reduce the microbial source. Carious lesions are caused by bacteria that break down the tooth structure, leading to decay. By restoring the tooth and removing the carious lesion, the microbial source is reduced, preventing further decay and promoting oral health. Restoring the function and form of the tooth are secondary objectives in this context.Rate this question:

Primary purpose of scaling and root?
- A.
To remove calculus & softened necrotic cementum
- B.
To remove epithelial attachment
- C.
All of the above
- D.
To remove sulcular epithelium
Correct Answer
D. To remove sulcular epitheliumExplanation
The primary purpose of scaling and root planing is to remove the sulcular epithelium. This procedure involves removing the diseased tissue and bacteria from the periodontal pockets, which are the spaces between the teeth and gums. By removing the sulcular epithelium, the dentist or dental hygienist can access and clean the root surfaces of the teeth, removing calculus and softened necrotic cementum. This helps to promote healing and prevent further progression of gum disease.Rate this question:

Clinical changes that may be apparent after scaling and root planning?
- A.
Gain in attachment and reduction of pocket depth
- B.
Gain in epithelial and new connective tissue attachment
- C.
Increase in width of attached gingiva
- D.
Reduction in inflammation and pocket depth
Correct Answer
D. Reduction in inflammation and pocket depthExplanation
After scaling and root planning, there is a reduction in inflammation and pocket depth. Scaling and root planning is a deep cleaning procedure that removes plaque and tartar from the teeth and roots. This helps to eliminate bacteria and toxins that cause inflammation and infection in the gums. As a result, the gums become healthier, and the pockets around the teeth become shallower. Therefore, the correct answer is reduction in inflammation and pocket depth.Rate this question:
