Applicability of the Moyers mixed dentition probability tables and new prediction aids for a contemporary population in India.

Introduction: The Moyers mixed dentition space analysis method is among the most commonly used in clinical practice for detecting tooth size-arch length discrepancies. In view of reported secular trends, racial, and sex differences in tooth sizes, the purposes of this study were to evaluate the applicability of Moyers probability tables in a contemporary orthodontic population of India and to formulate more accurate mixed dentition prediction aids.

Methods: Odontometric data were collected from 300 male and 300 female subjects of Indian descent, who had fully erupted mandibular permanent incisors and maxillary and mandibular canines and premolars.
