Abstract

Introduction: The dimensions of gingiva and different parts of the masticatory mucosa have a profound impact in periodontics as it governs the way; the gingival tissue reacts to various physical, chemical, or bacterial insults. The purpose of the following study was to assess the gingival thickness (GT) and correlate it to gender, presence of recession, and width of keratinized gingiva (WKG) in a subset of the Indian population.

Methods: A total of 400 subjects in the age range of 20-35 years (200 males and 200 females) were included in the study. Clinical parameters such as probing depth, recession depth, WKG, and GT were recorded for all the patients.

Results: The prevalence of thin biotype was 43.25%, and that of thick gingival biotype was 56.75%. The mean GT of central incisor, lateral incisor, and canine in Group I was 1.11 ± 0.17, 1.01 ± 0.16, and 0.82 ± 0.17 mm, respectively. No significant association was observed between the gender and the presence of gingival recession to GT. The mean WKG of central incisor, lateral incisor, and canine in Group I was 4.38 ± 1.18, 5.18 ± 1.25, 4.16 ± 1.16 mm, respectively. A positive correlation exists between WKG and the GT (P < 0.05).

Conclusion: It was concluded that the prevalence of thick and thin gingival biotype is 56.75% versus 43.25%, respectively, and there is no significant relationship between age, gender, and the presence of recession to gingival biotype. A positive correlation exists between WKG and the GT.

Keywords: Gender; gingival biotype; gingival recession; prevalence; width of keratinized gingiva.
