Incidence of mandibular 3rd molar impactions in different facial types of orthodontic patients seen at khyber college of dentistry.
Pak Oral Dental J Jan ;36(2):232-4.

Current study was performed to evaluate the incidence of mandibular 3rd molars impactions in patients of different skeletal facial types, seen at orthodontic department Khyber College of Dentistry Peshawar. Ninety pretreatment records of orthodontic patients (aged 16-35) including lateral cephalometric radiographs and orthopantomograms were assessed. The degree of impaction was determined by the Pell and Gregory classification system, and the facial type was categorized by the facial axis angle. Results showed that class ll impaction was most common in mesiofacial and dolicofacial patients while in brachifacial class I impaction was mostly observed. Overall impaction rate was more in females and most impactions were in class I and II. The study concluded that brachyfacial subjects over dolichofacial and mesiofacials provides increased space for full eruption of the mandibular third molars, so decreased mandibular 3rd molar impactions were seen in brachyfacials as compared to the other two groups.Current study was performed to evaluate the incidence of mandibular 3rd molars impactions in patients of different skeletal facial types, seen at orthodontic department Khyber College of Dentistry Peshawar.
