The best way to prevent exposure of dehiscene during surgical procedure is to
1. Elevate a double flap
2. Elevate full thickness flap
3. Elevate partial thickness flap
4. Elevate coronally repositioned flap
Periodontics
Answer: 3
The best way to prevent exposure of dehiscence during a surgical procedure is to elevate a partial thickness flap.
Which of the following structures is most likely to be damaged when per forming flap surgery on the complete mandibular arch?
1. Mental nerve
2. Attachment of mylohyoid muscle
3. Retromolar pad
4. Attachment of buccinator muscle
Periodontics
Answer: 1
The mental nerve is situated beneath the mandibular arch and is at risk during
flap procedures, especially when flaps are elevated or repositioned in that
area.
Which of part of the instrument should remain parallel (whenever possible) to the long axis of the tooth?
1. Blade
2. Cutting edge
3. Handle
4. Shank
Periodontics
Answer: 4
The part of the instrument that should remain parallel to the long axis of the tooth is the shank.
Angulation of a periodontal instrument refers to the
1) Angle between the face of the blade and the shank
2) Angle between the shank and the shaft
3) Angle between the face of the blade and the tooth surface
4) Angle between the shank and the tooth surface
Periodontics
Answer: 3
In periodontal instrumentation, angulation is crucial for effective scaling and root planing. The angulation refers to the relationship between the face of the instrument's blade and the surface of the tooth being treated. Proper angulation allows for optimal removal of calculus and plaque. The other options refer to different relationships that are not specifically defined as "angulation" in the context of periodontal instruments.
Systemic conditions which can affect the health of the gingiva are
1. agranulocytos
2. leukemia
3. granulocytopenia
4. all of the above
Periodontics
Answer: 4
agranulocytosis, leukemia, and granulocytopenia—can significantly impact the
health of the gingiva by affecting the immune response and increasing
susceptibility to infections.
Pyogenic granuloma is
1. Granulation tissue overgrowth
2. Capillary haemangioma
3. Sarcoidosis
4. Tuberculoid leprosy
Periodontics
Answer: 1
Pyogenic granuloma is a granulation tissue overgrowth.
Which aspect of instrument determines whether to remove gross deposits of calculus
1) Angulation and flexibility of blade
2) Angulation and flexibilty of shank
3) Angulation and length of blade
4) Angulation and length of shank
Periodontics
Answer: 2
The angulation and flexibility of the shank are crucial in determining the ability of an instrument to remove gross deposits of calculus. The shank of a dental instrument, such as a scaler or curette, must be designed to allow for proper access and manipulation around the curves and contours of teeth to effectively remove calculus. While the blade also plays a role, the shank's design is more influential in reaching and adapting to the tooth's surface.
The outcome of results of laterally positioned flap depends on
1) Presence of sufficient bone support at donor site
2) Thickness of attached gingiva at donor site
3) Width of attached gingiva at donor site
4) All of the above
Periodontics
Answer: 4
Explanation:The success of a laterally positioned flap in periodontal surgery is influenced by several factors, including the presence of sufficient bone support at the donor site, the thickness of attached gingiva at the donor site, and the width of attached gingiva at the donor site. All these factors contribute to the healing and stability of the flap.
