Which of the following considers thickness of plaque on tooth
1. Periodontal index of Russell
2. Loe and Sillness index
3. Sillness and Loe index
4. OHI-S index
Pedodontics
Answer: 3
The Sillness and Loe index considers the thickness of plaque on the tooth.
Gingival clefts are caused by
1. Trauma from occlusion
2. Faulty brushing technique
3. Normal frenal pull
4. Improper use of floss
Pedodontics
Answer: 1
Gingival clefts are caused by trauma from occlusion.
A patient has cheilosis, angular stomatitis, glossitis, red, itching eyes. The periodontal surgery that was performed one week ago has not healed properly. Deficiency of which of the following vitamins is most likely
1. Thiamin
2. Riboflavin
3. Tocopherol
4. Calciferol
Pedodontics
Answer: 2
Deficiency of riboflavin is most likely in a patient with cheilosis, angular stomatitis, and glossitis.
CADIA is used to assess
1. Occlusal trauma
2. Furcation involvement
3. Gingival enlargement
4. Periodontal disease progression
Pedodontics
Answer: 4
CADIA is used to assess periodontal disease progression.
Trauma from occlusion in the absence of inflammation causes
1. Only reversible changes in periodontium
2. Always irreversible changes in periodontium
3. No changes in periodontium
4. Such condition does not exist
Pedodontics
Answer: 1
Trauma from occlusion in the absence of inflammation causes only reversible changes in the periodontium.
Probing depth can be accurately assesed on proximal surface of a tooth by
1. Positioning probe at right angles to tooth surface
2. Walk the probe as close to the contact area as possible
3. Slant the tip of probe apical to contact area
4. Using Naber"s probe
Pedodontics
Answer: 3
Probing depth can be accurately assessed on the proximal surface of a tooth by slanting the tip of the probe apical to the contact area.
In a deep pocket of 6 mm, calculus is found only as a thin ring at apical third. It may be due to
1. Calculus formation occurs only at bottom of the pocket
2. Fracture and dislodgement of enamel part of calculus
3. Both A and B
4. None of the above
Pedodontics
Answer: 2
In a deep pocket of 6 mm, calculus found only as a thin ring at the apical third may be due to fracture and dislodgement of the enamel part of calculus.
The average leeway space in the maxilla (both right and left sides) is
1. 1.8 mm
2. 2.7 mm
3. 3.6 mm
4. 0.9mm
Pedodontics
Answer: 1
The average leeway space in the maxilla (both right and left sides) is 1.8
mm.
Leeway space is the amount of space available for the movement of teeth in the
maxilla and mandible during orthodontic treatment. It is calculated by
subtracting the combined mesiodistal width of the mandibular incisors from that
of the maxillary incisors. This space is crucial in determining the potential
for tooth movement, particularly in cases where there is crowding. The answer of
1.8 mm is a commonly accepted average value in the field of orthodontics.
