All the questions have been directly picked from Carranza 11th edition
1. With ageing , gingival connective tissue becomes
a. Fine and thick
b. Coarse and dense
c. Firm and smooth
d. All of the above
Ans: b coarse and dense (Carranza 11th
edition page no. 53)
2. Elastic fiber content of
periodontal ligament with age
a. Remains same
b. Increases
c. Decreases
d. Neither increases nor decreases
Ans: b. increases (Carranza 11th edition
page no 54)
3. With increase in age,
keratinisation of gingiva
a. Increases
b. decreases
c. Remains the same
d. Increases and then decreases
Ans: b Decreases ( Carranza 11th edition
page no 52)
With increase in age, keratinisation of gingiva
decreases while the width of the attached gingiva increases
With increase in age:
i.
keratinization of gingiva Decreases
ii.
width of the attached gingiva Increases
iii.
collagen fibre decreases
iv.
elastic fibres increases
v.
there is increased in scalloping of the cementum
vi.
number of the fibroblasts decreases
vii.
stippling decreases
4. The increase in thickness of
cementum with ageing is greater
a. Coronally
b. Apically
c. Labially
d. At midroot
Ans: b Apically (Carranza 11th edition
page no 54)
An increase in cemental width is a common finding;
this increase may be 5 to 10 times with increasing age.' This finding is not
surprising because deposition continues after tooth eruption. The increase in
width is greater apically and lingually.
5. Which of the following is a
feature of aging periodontium?
a. increased keratinisation of gingiva
b. decrease in width of attached gingiva
c. Increase in cell number and decrease in fiber
content of periodontal ligament
d. Scalloping of mineralised tissue
Ans: d. Scalloping of mineralised tissue ( Carranza
11th edition page no 52-54)
6. What is the effect of ageing on
the width of attached gingiva?
a. Increases
b. Decreases
c. First increases and then decrease
d. Neither increases nor decrease
Ans: a Increases ( Carranza 11th edition
page no 52-53)
With continuing gingival recession, the width of the
attached gingiva would be expected to decrease with age, but the opposite
appears to be true.
7. Which of the following is not a
significant risk factor for periodontal disease?
a. Diabetes
b. Smoking
c. Ageing
d. Poor oral hygiene
Ans: c Ageing ( Carranza 11th edition
page no 55)
Conclusions from these studies are strikingly consistent
and show that the effect of age is either nonexistent or provides a small and
clinically insignificant increased risk of loss of periodontal support
