In an adult patient with chronic adult periodontitis the most successful approach to treatment is:?
- Surgery
- Extreme initial treatment followed by reviews every year
- Initial periodontal therapy followed by maintenance therapy alone
Correct Answer

A. Initial periodontal therapy followed by maintenance therapy alone

Explanation

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.

In an adult patient with chronic adult periodontitis the most successful approach to treatment is?
- Surgery
- Extreme initial treatment followed by reviews every year
- Initial periodontal therapy followed by maintenance therapy alone
Correct Answer

A. Initial periodontal therapy followed by maintenance therapy alone

Explanation

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 a thorough initial treatment to remove plaque and calculus, followed by regular maintenance visits to prevent the recurrence of periodontal disease. This approach has been shown to effectively control the progression of periodontitis and maintain periodontal health in the long term. Surgery and extreme initial treatment followed by yearly reviews may be considered in more severe cases, but the initial periodontal therapy followed by maintenance therapy alone is the most successful approach in general.

Incision in the esthetic zone with regards to semi-lunar graft treatment of gingival recession: ?
- Should whenever possible be vertical
- Should where ever possible be made through thin connective tissue
- Should initially be made of full thickness
- Initially should be made at the mucogingival junction
Correct Answer

A. Initially should be made at the mucogingival junction

Explanation

The incision in the esthetic zone should initially be made at the mucogingival junction. This is because the mucogingival junction provides a stable and predictable reference point for the incision. It helps to ensure that the incision is placed at the correct level and allows for precise control of the depth and direction of the incision. By starting the incision at the mucogingival junction, the surgeon can create a clean and well-defined flap that can be easily elevated for the semi-lunar graft treatment of gingival recession.

Horizontal bone loss is present in : ?
- Localized aggressive periodontitis
- Generalized aggressive periodontitis
- Intrabony pockets
- Acute necrotizing ulcerative gingivitis
- Chronic periodontitis
Correct Answer

A. Chronic periodontitis

Explanation

Horizontal bone loss is a characteristic feature of chronic periodontitis. This condition is characterized by the gradual and progressive loss of the alveolar bone around the teeth, resulting in the formation of horizontal defects. Unlike vertical bone loss, which is seen in aggressive forms of periodontitis, horizontal bone loss occurs when the bone resorption is relatively uniform around the tooth, leading to a more even and consistent reduction in the bone level. Therefore, chronic periodontitis is the most likely condition associated with horizontal bone loss.

- Translocation of microorganisms
Correct Answer

A. Translocation of microorganisms

Explanation

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.

Main aim of restoration of carious lesion in phase-I therapy?
- To restore function of tooth
- To restore form of tooth
- All of the above
- To reduce microbial source
Correct Answer

A. To reduce microbial source

Explanation

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.

Primary purpose of scaling and root?
- To remove calculus & softened necrotic cementum
- To remove epithelial attachment
- All of the above
- To remove sulcular epithelium
Correct Answer

A. To remove sulcular epithelium

Explanation

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.
