Deviations in which of the following stages of development of the dentition result in supernumerary teeth?
1. Apposition
2. Morphodifferentiation
3. Initiation
4. Multiplication
Pedodontics
Answer: 3
Supernumerary teeth, or extra teeth beyond the normal complement, typically arise from deviations during the initiation stage of dental development. This stage involves the formation of the dental lamina, which is responsible for the development of teeth. Abnormalities in this process can lead to the formation of additional teeth.
In a bruxism patient the muscle that exhibits overdevelopment is
1. Lateral pterygoid
2. Masseter
3. Temporalis
4. Internal pterygoid
Pedodontics
Answer: 2
In a bruxism patient, the muscle that exhibits overdevelopment is the masseter.
While using a periodontal probe to measure the depth of the periodontal pocket the pocket is measured from
1. Free gingival margin to the cementoenamel junction
2. Junctional epithelium to the free gingival margin
3. Base of pocket to the cementoenamel junction
4. Base of pocket to mucogingival junction
Pedodontics
Answer: 2
While using a periodontal probe, the pocket is measured from the junctional epithelium to the free gingival margin.
The best way to detect bony defects is
1. Radiograph at different angulations
2. Careful probing
3. Surgical exposure
4. Measurement of pocket depth
Pedodontics
Answer: 3
The best way to detect bony defects is surgical exposure.
"V" shaped bone loss is seen in
1. Trauma from occlusion
2. Simple periodontitis
3. Orthodontic tooth movements
4. All of the above
A "V" shaped bone loss is seen in trauma from occlusion.
In a patient without gingival recession, the distance between base of pocket and cementoenamel junction is 4 mm and that of free gingival margin to cementoenamel junction is 3 mm. Total depth of the pocket
1. 7 mm
2. 3 mm
3. 4 mm
4. 10 mm
In a patient without gingival recession, the total depth of the pocket is 7 mm.
Which of the following is more common in children
1) Gingivitis
2) Periodontitis
3) ANUG
4) Pericoronitis
Pedodontics
Answer: 1
Gingivitis is the inflammation of the gums that is more common in children due to poor oral hygiene and accumulation of dental plaque. Periodontitis, on the other hand, is a more severe form of gum disease that typically occurs in adults due to prolonged or severe gingivitis. ANUG (Acute Necrotizing Ulcerative Gingivitis) is a specific type of severe gingival infection that is less common in children than gingivitis, and pericoronitis is an infection that occurs around the gum flap when a tooth is partially erupted, which is more common in teenagers and young adults.
