Aging and the periodontium

 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
