COMPARISON OF LIP LENGTH AND THICKNESS AMONG THREE VERTICAL GROWTH PATTERNS IN SKELETAL CLASS II JAW RELATIONSHIP IN THE POPULATION OF PESHAWAR

Abstract

Objective: To compare upper lip length and thickness and lower lip length and thickness among high angle, normal angle and low angle patients with a skeletal class II jaw relationship and to compare these four variables among the sexes in the population of Peshawar.

Methods: This cross-sectional study was conducted at Khyber College of Dentistry, Peshawar in January and February, 2021. Clinical and radiographic records of 120 patients, with the age range of 9 to 33 years, were used. 60 males and 60 females were equally distributed into 3 groups based on their vertical growth pattern, with 40 patients each in the high angle group, normal angle and low angle group. The one-way ANOVA and independent-samples t test were used for comparison between the three groups and sexes for the four research variables. P value of lesser or greater than .05 was considered significant.

Results: The mean age for the entire sample was 17.61 years ± 5.14. There was no statistically significant difference in means of lip lengths and thicknesses amongst the 3 groups and sexes.

Conclusions: Lip lengths and thickness are similar among the three vertical growth patterns and among the sexes in skeletal class II in the population of Peshawar.
