title: Assessment of crown angulations, crown inclinations, and tooth size discrepancies in a South Indian population.
abstract: OBJECTIVE
  The aim of this study was to assess crown angulations, crown inclinations, and tooth size discrepancy in a sample population from Davangere, South India.
  
  
  METHODS
  One hundred adults (50 male and 50 female) of age 18-30 years, with Angle's class I ideal occlusion and balanced profiles, were selected for the study. Study models were prepared and crown angulations and crown inclinations were measured using a customized protractor device. Bolton's analysis was used to measure the tooth size discrepancies.
  
  
  RESULTS
  Maxillary and mandibular teeth had less crown angulations. Maxillary and mandibular incisors and maxillary molars showed increased crown inclinations, whereas mandibular molars and premolars had less crown inclinations than the original Andrews sample. The mean maxillary and mandibular tooth size ratios, overall and anterior, were similar to Bolton's ratios.
  
  
  CONCLUSIONS
  The finding of this study indicates that there are possible racial and ethnic factors contributing to variations in crown angulations and crown inclinations.
