ABSTRACT:

The aim of this study is to evaluate permanent maxillary first molar rotation in class II division I malocclusion. Cross-sectional survey was carried Punjab Dental Hospital, Lahore from April 2019 to September 2019. One hundred and fifty patients of 12 to 21 ages, irrespective of gender were selected. Maxillary and mandibular casts of these patients were collected. One angular was made on the photographs of study models. This angle was formed by the lines passing through the tips of the buccal cusps of the upper molars of both left and right sides to the midpalatal line respectively. The midpalatal line was identified by an anterior and posterior point along mid palatal raphe. There were 32% males and 68% females with mean±SD of age 16.55±2.61 years. 22.1% have left side positive angles 63.5% patients have right side positive angles. Regarding rotation of first molar in class II division I, 118 patients (78.7%) have rotations and 32 patients (21.3%) have no rotations. The individuals with class II division 1 malocclusion present greater mesiopalatal rotation of the maxillary first molars. Molar rotation was more on the right side as compared to the left and in class II cases.
