Abstract

To determine the association of maxillary & mandibular base lengths with skeletal class I, II and III. This cross sectional study was conducted from the data of 58 patients (females=43, males=15). Patients with the presence of class I, II or III malocclusion & presence of all fully erupted permanent teeth up to first molar were included in the study. Measurements were performed on pre-treatment lateral cephlograms. Anatomic tracings & location of dentoskeletal landmarks were manually conducted. Measurements were recorded on a predesigned Proforma. Stratified sampling was used to obtain the sample size for each class which was 21, 33 & 4 for class I, II & III respectively. Data were analyzed using SPSS 20.0. One Way analysis of variance was run to explore the effect of skeletal classes on mandibular & maxillary base lengths. There were no statistically significant differences found between the means of maxillary & mandibular base lengths & skeletal classes (F (2,55) = 0.940, p = 0.397) & (F(2,55) =1.983 , p = 0.147) respectively. Study sum up that maxillary & mandibular base lengths were not affected by the skeletal malocclusion.
