To assess the effect of different dental malocclusion and crowding groups on keratinized gingival width in the mandibular anterior tooth region and their significant relation. This cross-sectional study was conducted at the Institute of Dentistry, Orthodontics Out Patient Department, LUMHS, Jamshoro. The study included a total of 136 patients, comprising 44 males (32%) and 92 females (68%). The epitool sample size calculator was used to calculate the sample size. Patients meeting the selection criteria were enrolled in the study and categorized into three groups: Angle Class I malocclusion, Angle Class II, and Angle Class III. Each Angle classification group was further subdivided based on the degree of anterior region crowding. After evaluation the score was calculated. Data was analyzed via SPSS version 22. Descriptive statistics such as percentage, frequency distribution, cross tabulation were included in data analysis. The level of significance was set at <0.05%. The average age of the patients was 18.15±4.085. Results from ANOVA test showed that keratinized gingival width in lower anterior teeth had no significant difference when related to Angles classification except for the lower left lateral incisor with a P value of (P value 0.010). The difference in keratinized gingival width of different crowding groups assessed with the application of ANOVA test were not statically significant except for the lower right lateral Incisor & left Lateral incisor in which this difference was noted to be statically significant (p < 0.05).
