【 摘 要 】

Background: The aim of this study was to find interrelation among embrasure configuration and recession of median papilla was. To assess impact of extent from the point of contact to bone crest (BC) on the existence of the interproximal papilla by radiographic method and to evaluate the extent between the papilla tip (PT) to the BC by comparing clinical and radiographic methods were the objectives. Methods: With the use of periapical radiographs (paralleling cone technique in RVG with grid) of the maxillary central incisors, the central papilla was evaluated in 100 adults. To evaluate and compare the extent between PT and BC, bone sounding was used. The vertical measurements were: papilla recession, contact point (CP) to BC, CP to proximal cement-enamel junction (pCEJ), and papilla height. The interdental width was the horizontal measurement. According to width interproximally and pCEJ to point of contact extent, total four study groups were divided: long narrow, short narrow, long wide, and short wide. Results: The comparison among radiographic method and clinical method revealed that there was statistically no significant difference between two methods among long-narrow and short-wide group. However, statistically significant difference was noted among short-narrow and long-wide group. Conclusion: Median papilla recession was associated with a wide-long type of embrasure configuration. Although many features such as periodontal phenotype and shape of teeth may influence the probability of the existence of the inter-proximal papilla, therefore the interconnections between these factors are not clear and require further research.
