Evaluation of Golden Proportion of Maxillary Anterior Teeth in Different Morphological Facial Types in A Sample of Class I Normal Occlusion (Photographic, Cross Sectional Study)

Since the face is the most visible part of human anatomy and the maxillary anterior teeth hold a significant effect during smiling, this study aims to evaluate the golden proportion of the maxillary anterior teeth in different morphological facial types and detect possible gender differences in a sample of class I normal occlusion. The sample consisted of 82 Iraqi adults (40 males and 42 females) aged (18-25) years. Each individual was clinically examined, frontal facial and intraoral photographic records were performed for each individual; the facial index from facial measurements and golden proportion from dental measurements were calculated. Descriptive statistics were obtained for the measured variables for both genders and independentsamples t-test was performed to evaluate the genders difference and pearson coefficient used to correlate the facial index and golden proportion of maxillary anterior teeth.the results revealed that the leptoprosopic type comprised 78% of the sample and 20% of the sample was of mesoprosopic type, whereas the remaining 2% of euryprosopic type was excluded from the study. The results showed a high significant gender difference in facial measurements and non-significant gender difference in dental measurements, the golden proportion of maxillary anterior teeth did not present in the different facial types, and there was a non-significant facial type difference in golden proportion; therefore the golden proportion did not depend on gender and facial form.
