Prediction of the Interdental Papilla Presence between the Upper Central Incisors Based on the Distance from the Contact Point to the Crest of Bone and Interdental Distance

Abstract

Background: The appearance of interdental papillae plays an important role in the final aesthetic outcome, especially in exposed region as is interdental papilla between central upper incisors. The aim of this study, is to determine factors associated with bone morphology, which can influence the appearance of this papilla. Materials and methods: 50 subjects in the range of 20-30 years of age with healthy periodontal tissues were examined. Presence of interdental papilla between central maxillary incisors was determined using classification proposed by Nordland and Tarnow. Intraoral radiographs were utilized to measure distance from contact point to the crest of bone and interdental distance at the level of cementoenamel junction using a computer programme. Results: Statistically significant correlation between papilla presence and distance from the contact point to the crest of bone (p < 0,0001) was found. Also significant relationship between papilla presence and interdental distance (p < 0,0001) was found. The value of prediction of papilla presence for both factors was inferred from data analysis. Conclusion: Presence of interdental papilla is influenced by various factors, including distance from contact point to the crest of bone and interdental distance. Modification of these distances can influence the final aesthetic outcome.
