Avaliação clínica e radiográfica da variação da papila gengival e suas proporções

Activity: Supervision


INTRODUCTION: The elegance of the smile is increasingly desired by society. Gingival tissue has proved to be a crucial factor in this harmony. The proportion between teeth and interdental papillae can help to achieve that desire. PURPOSE: To determine and quantify mathematically the influence of the location of the interdental papilla on the smile, relatively to the size of the teeth’s crown and the location of the alveolar crest. METHODS: 100 standardized photographs and radiographs were taken in 50 patients (22 men and 28 women) with an average of 22 years old. Clinical measurements of the crown’s heights and widths of maxillary incisors were made. The photographs were assessed: interdental papilla heights, exhibited gingiva height and interdental papilla exposure in the smile. Through radiographs it was possible to analyze radiographic height of the interdental papilla. Statistic analysis was performed using Student t test, Mann-Whitney, ANOVA, Chi-Square and continuity test. Correlation between variables was performed through Pearson’s correlation. RESULTS: For p-value < 0,05, the height of the interdental papilla is higher in mesial and in the maxillary central incisors; the proportion between the papilla and the crown’s height is greater in mesial; the radiographic height of the papilla is higher in distal; the proportion between crestal papilla and crown height is higher in distal and in the maxillary lateral incisors and exposure of papillae is greater in women. CONCLUSION: The papilla’s variation is determinant for a good oral aesthetic. Through the calculated proportion, it is possible to determine the ideal height of the interdental papillae according to the variability of the clinical crowns’s size
