摘要

The presence of interproximal dental papillae between maxillary anterior teeth is a key esthetic factor of great concern to dentists and patients. The purpose of this study was to determine the factors that might influence the presence or recession of the interproximal dental papilla between maxillary anterior teeth. A total of 102 interproximal sites of maxillary anterior teeth in 30 patients were examined. Tempbond(superscript TM) mixed with barium sulfate was applied by a periodontal probe to the tip of the interproximal dental papillae and mucogingival junction. Periapical films using parallel technique were taken. The presence of interproximal dental papilla was determined on radiographs. If the tip of the interproximal dental papilla was at the base of the contact point, the papilla was recorded as being present. If not, the papilla was considered to be recessed. The radiographs were transferred into a computer and calibrated and measured with the image J software. The following factors were measured : [1] the distance from the base of the contact point to the bone crest. [2] The length of the interproximal dental papilla. [3] The width of keratinized gingiva. [4] The interdental distance. Results revealed that: [1] The number of interproximal dental papilla present had a significant decrease (p＜0.001) when the distance from the contact point to bone crest increased. [2] The number of interproximal dental papilla present also had a significant decrease (p＜0.05) when the interdental distance increased. [3] The distance from the contact point to the bone crest was the predominant factor, especially when it was 5 mm. Results also showed that this noninvasive method using radiographs is a reliable guideline for clinical evaluation of the interproximal dental papilla. To understand better the interaction of different factors associated with the presence of interproximal dental papilla, further studies are indicated.
