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.

1) Pin retained amalgams
2) Cast gold crowns
3) Full upper and lower dentures
4) Stainless steel crowns

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.
