Aims: To determine and compare the palatal dimensions in mixed Indian population with different malocclusions and to find correlation among them. Materials and Methods: The sample consisted of 152 study models of children aged 13-16 years consisting of 76 males and 76 females obtained from Govt. teaching institution divided into Angle's Class I (40), Class II (80) and Class III (32) based on molar relationship and cephalometric evaluation. Ten palatal parameters were measured using Korkhaus gauge, which included arch width at the canine, 1 st premolar, 2 nd premolar and 1 st molar, arch length, palatal depth at canine, 1 st premolar, 2 nd premolar, and 1 st molar and arch perimeter. The mean and standard deviation were calculated, analysis of variance (ANOVA), independent student t test and Pearson's correlation coefficient were used for the statistical analysis. Results: Angle's Class I occlusion group showed widest intercanine width. Palatal depth was shallowest in Class II Div 2 malocclusion and Class III malocclusion group showed shortest arch length and arch perimeter. There was no difference in palatal dimensions in between gender. Various palatal parameters were co related to each other. Conclusions: Significant differences existed in most of palatal dimensions among different types of Angle's occlusal relationships but no significant changes were observed among two genders. Many palatal dimension parameters were correlated to each other.
