Abstract

Background:  Class II malocclusion is commonly present along with a variety of skeletal and dental malformations. The aim of the present study was to examine whether a putative relationship exists between developing class II malocclusion and various dental anomalies, in comparison with that of Class I malocclusion. The study also aims to compare the cephalometric parameters of patients with developing class II malocclusion with that of Class I malocclusion. The study sample included 40 children between age group of 12-16yrs among 440 school children screened in our department. The sample was divided into two groups according to molar relationship. Group 1 of 30 children with class II molar relation and group 2 of 10 children with class I molar relation. Cephalometric parameters were analyzed on the lateral cephalograms for both the groups. Study models and OPG were analyzed for the presence of different developmental dental anomalies in both the groups. Dental anomalies such as mesiodens, rotations, canine ectopia, canine impaction and third molar agenesis were recorded. The study concluded that rotation of teeth forms the major contributor in the occurrence of class II malocclusion, when compared with other dental anomalies. Mesiodens forms the minor contributor in the occurrence of class II malocclusion.

Keywords: Class II malocclusion, Rotations, Canine Ectopia, Canine Impactions and Third molar agenesis.
