Abstract

Objective: To determine the frequency of gingival phenotype tooth shape of maxillary central incisors in respective gingival phenotypes.

Study Design: Analytical cross-sectional.

Place and Duration of Study: Fatima Memorial Hospital, Lahore, Pakistan, from Mar to Sep 2018.

Methodology: A total of 201 patients reporting to the Department of Periodontology, fulfilling the inclusion criteria were included in the study. A Michigan "O" Probe was used to evaluate the gingival phenotype and tooth shape. If the probe outline was even slightly showing through the gingiva with the naked eye, the phenotype was regarded as thin otherwise it was labelled thick. A single examiner recorded both the gingival biotype and the shape of the clinical crown.

Results: Analysis of the data revealed that thick biotype was found in 66.17% of patients whereas thin biotype was found in 33.83%. Out of this sample, 70.70% males and 63.00% females had thick phenotype respectively whereas thin phenotype was found in 29.30% males and 37.00% females. Thick phenotype was associated with square tooth shape whereas thin phenotype was associated with slender tooth shape (p-value<0.05).

Conclusion: Thick biotype was more prevalent than thin biotype and thick phenotype was associated with square tooth shape whereas thin phenotype was associated with slender tooth shape.
