Selection of maxillary anterior teeth for complete dentures is crucial in clinical practice and controversy about the validity of even the best method to employ still exists. Leon Williams formulated and publicized a method called the “Geometric theory” which is still widely used. Williams believed that there exists a relationship between the face-form and the form of the maxillary central incisor in most people and that this relationship should be taken into account in the tooth selection procedure.A Cross-sectional, descriptive study was conducted in an institution, on randomly selected individuals. The study group consisted of adult patients who attended the outpatient Department of Prosthodontics from June 2019- March 2020.86000 case sheets were evaluated and Chi-square test and frequency analysis was used to explore the relationship between two variables.Leon Williams criteria was fulfilled by only 41% individuals Ovoid face form 41% is more common in indian population as compared to other forms.Ovoid and square tapering tooth forms are more common compare to other tooth forms 30% with square tooth form being the least 12%.In females leon williams criteria was more matched than males. But the difference was not significant. This study concludes that there is a much greater percentage of dissimilarity between incisor and face-form, in sample Indian population. The “Williams’ law of harmony” to select artificial teeth stands inconclusive in the sample Indian population both in males and females.
