Anterior Maxillary Tooth Proportions and the Golden Percentage Concept in the Deutero-Malay Race (Study on Dental Students in the Faculty of Dentistry, Universitas Indonesia)
摘要
The anterior maxillary tooth proportions are an important component of anesthetic smile. Harmonization of the face and the observed proportions affect the acceptability of a smile's esthetics. Many concepts have been proposed as guidelines for esthetic dental proportions, such as the golden proportion and the golden percentage. However, no study has yet investigated the proportions of the maxillary anterior tooth widths in the Deutero-Malay race, the largest population in Indonesia. The aim of this study was to evaluate the maxillary anterior tooth width proportions among students of Deutero-Malay origin in the Faculty of Dentistry, Universitas Indonesia (FKG UI) and to verify whether these proportions match the golden percentage. Methods: This descriptive study was conducted on 100 FKG UI students of Deutero-Malayorigin. Subjects were queried regarding their satisfaction with the overall appearance of their smiles (harmonization of face, mouth, and teeth). Study models were made for all subjects from maxillary impressions. The outermost point of the maxillary anterior tooth width, from the frontal aspect, were projected onto millimeter-block paper and measured. The percentage was obtained by dividing the width of each anterior tooth by the total anterior tooth width and the data were then tabulated and analyzed statistically. As a results, the proportions of the maxillary anterior tooth widths were 12, 16, 22, 22, 16, and12%. These proportions were considered esthetically satisfying to 97% of the study subjects. It was conclude that the maxillary anterior tooth widths among FKG UI students of Deutero-Malay origin showed a specific proportion that does not follow the golden percentage proposed in earlier studies on subjects of different origins. However, the observed proportion was considered esthetically satisfying by the study subjects.
