Abstract
Objective: The objectives of this investigation were to describe the prevalence of
anterior tooth size discrepancies in Skeletal Class III with mandibular prognathism,
and whether sexual dimorphism exists for anterior tooth size ratios.
Methods: The measurements were obtained from 40 study models with both sexes
(19 female, 21 male). All patients were Saudi nationals, between the ages of 19 to 30
years old. Descriptive statistics and t-test were used for the analysis of the data.
Results: Subjects having skeletal Class III with mandibular prognathism showed
highly significant anterior ratio (80.6 +2) compared to the Bolton Study (P<0.001), a
high prevalence of anterior tooth size discrepancy, no sexual dimorphism and
significant difference in some mesiodistal tooth size difference between sexes.
Conclusion: Tooth size analysis is an important diagnostic tool and should be
included as one part of the records when establishing treatment planning.
