The purpose of this study was to compare skeletal maturity index and dental developmental stages based onskeletal malocclusion. A total of 192 patients (89 male and 103 female) between 6 to 14 years old were selected for this study andunderwent cephalograms, panorama radiographs, and hand-wrist radiographs. Any syndromic cases were excluded. Selected clinical parameters were dichotomised for statistical analysis. Chi-square, logistic regressionanalysis, and independent t-tests were used for the statistical evaluation. Canine, first molar, and second molar calcification were significantly associated with skeletal maturity in thelogistic regression model (p < 0.05). In addition, patients who had higher skeletal maturity index were 11.43times more likely to be female than those who had lower skeletal maturity index (p < 0.001). The patients withskeletal class II malocclusion displayed significantly higher dental developmental stage in canines, first premolars,first molars, and second molars than the patients with class III malocclusion (p < 0.05). The dental developmental stage of the patients was significantly associated with skeletal maturity. In addition,there was a significant difference between class II and class III malocclusion with some types of tooth calcification.
