title: Dimensional influence of interproximal areas on existence of interdental papillae.
abstract: BACKGROUND
  Restoring papillae in the gingival embrasures of the esthetic zone is a key consideration in periodontal, restorative, and orthodontic treatment. This study analyzes the existence of interdental papillae with regard to the vertical dimensions between the contact point and the alveolar crest and horizontal dimensions between adjacent roots.
  
  
  METHODS
  A total of 259 papillae, in 60 patients, were examined. All patients were indicated for full-thickness periodontal flap surgery. A mucoperiosteal flap was raised and, after thorough debridement, horizontal and vertical dimensions between adjacent roots were recorded. The incidence of papillae was analyzed using χ(2) for linear trend analysis.
  
  
  RESULTS
  Interdental papillae were present in 85.7% of the cases when the vertical dimensions were 4 mm (P <0.05). Also, papillae were present in 78.5% of cases when the horizontal dimensions were between 0.5 and 1 mm (P <0.05).
  
  
  CONCLUSIONS
  The vertical and horizontal dimensions of interproximal areas had a substantial, independent, and combined effect on the existence of interproximal papillae.
