Bolton discrepancies among different classes of malocclusion in Peshawar population.
Pak Oral Dental J Jan ;34(4):647-50.

For proper alignment and good interdigitation at the end of orthodontic treatment, the tooth size should be in harmony in both dental arches to achieve normal overjet and overbite. Bolton’s analysis should be taken into consideration when diagnosing, treatment planning and predicting prognosis in clinical orthodontics. Many other methods have been devised to estimate tooth size discrepancy but Bolton’s analysis is still widely used in clinical practice. A sample of 90 patients with age ranging from 13 to 30 years were included in the study. The greatest mesiodistal width of each tooth in maxillary and mandibular arches (except for second and third molar) was measured using manual vernier caliper. Each tooth was measured twice from right first permanent molar to left fist permanent molar in each arch. The readings were then used to compute the anterior and overall Bolton’s ratios for each patient. The mean age was 20.75±2.9. Female to male ratio was 1.17:1. No statistical significant differences were present among different malocclusion groups with P-value of 0.38 for anterior ratio and for 0.122 overall ratio. There were no significant difference among males and females with P-value of 0.361 for anterior ratio and 0.592 for overall ratio.
