This study was designed to verify if the dimension of the interdental papilla may be a prognostic factor for the clinical outcome of the coronally advanced flap (CAF) in the treatment of gingival recessions.Thirty-three Miller Class I recessions were treated in 33 patients using the CAF procedure. Two types of measurements were performed: 1) clinical measurements (probing depth, recession depth, width of keratinized tissue, clinical attachment level) were recorded at baseline and 3 months after surgery and 2) all recessions were photographed and transformed into computer images. A specific software allowed recording of both linear and square measurements. The following digital measurements were recorded at baseline: 1) base, height, and area of the mesial and distal papillae adjacent to the involved tooth and 2) width/depth of the recession and the area of the exposed root surface of the involved tooth. The residual recession area, if any, was recorded 3 months after surgery. The digital measurements of the height and of the area of the papilla were used in statistical analysis (multiple linear regression and logistic regression) to evaluate a possible correlation with root coverage (mm2) and/or with complete root coverage.Root coverage was not significantly correlated to the papilla area (P= 0.3692) or to papilla height (P= 0.0968). The complete root coverage was not correlated to the papilla area (P= 0.3181), but it was correlated to papilla height (P= 0.0499).This study indicates that the root coverage following CAF procedure is not significantly correlated to papilla dimension. However, complete root coverage is significantly more frequent in sites with lower height of the adjacent papilla.
