# Width of attached gingiva:

# Width of attached gingiva:
A. Decreases with age
B. Increases with age
C. Remains the same
D. Is not age-related

Answer:
B. Increases with age

Because the mucogingival junction remains stationary throughout adult life, changes in the width of attached gingiva are caused by the modification in the position of the coronal end.

The width of attached gingiva increases with age and in supraerupted teeth, with the wear of the incisal edge and continued tooth eruption. The gingival margin of the tooth, therefore the entire dentogingival complex, moves coronally with a resulting increase in width of the attached gingiva.

Most Important Operative Dentistry MCQs With Explanations

1. The following chemically bond to the tooth: A. Composite resin. B. Dental sealants. C. Glass ionomer cement. *** D. All of the above. 2. Compomer restorative materials are: A. Glass ionomer with polymer components B. Resin systems with fluoride containing glasses. *** C. Composite resin for cervical restorations only. Explanation: The composition of compomers is similar to that of a dental composite however it has been modified, making it a polyacid-modified composite. This results in compomers still requiring a bonding system to bond to tooth tissue. Although the name compomer implies that the material possesses a combination of characteristics of both composite and glass ionomers, these materials are essentially polymer-based composites that have been slightly modified to take advantages of the potential fluoride-releasing behavior of glass ionomers. 3. Loose enamel rods at the gingival floor of a class II amalgam cavity should be removed using : A. Straight chisel...
