| Popis: | BACKGROUND: A method to predetermine the maximum root coverage level (MRC) achievable with surgery was recently presented. The present study evaluates the predictability of such a method by comparing the predetermined MRC with that effectively achieved by means of root coverage surgical procedures. METHODS:A total of 50 patients with single and multiple recession defects were enrolled. MRC was predetermined by an independent periodontist by assessing the ideal height of the interdental papilla. The distance from the apical reference point of a stent (StRP) and the MRC was measured 7 days before root coverage surgery. A total of 135 Miller Class I, II, and III gingival recessions were treated with the coronally advanced flap (CAF) or with the subepithelial connective tissue graft (SCTG). The distance from StRP and the gingival margin (GM) was measured by another independent periodontist 15, 30, and 90 days after surgery. RESULTS:In 97 (71.8%) of 135 treated gingival recessions, the StRP-MRC distance coincided exactly with the StRP-GM distance. No statistically significant difference was demonstrated in the cases with exact predetermination between gingival recessions belonging to the maxilla or mandible and between gingival defects treated with CAF or SCTG. The StRP-MRC distance measured before surgery was greater in 24 recession defects (17.7%) and lower in 14 gingival recessions (10.3%) than the StRP-GM distance measured 90 days after surgery. More cases of underestimation and fewer cases with overestimation of the level of root coverage were found in the SCTG group compared to the CAF group. The difference was statistically significant (P |
