Prediction of root coverage for single recessions in anterior teeth: a 6-month study.

Abstract

The aim of this study was to evaluate the predictive values of baseline inter-dental papilla height (IPH), loss of inter-dental papilla height (LPH), avascular exposed root surface area (AERSA) and inter-dental clinical attachment level (ICAL) measurements on complete root coverage (CRC) of single recession defects treated with coronally advanced flap and connective tissue graft technique (CAF+CTG). A total of 122 patients with one isolated gingival recession were enrolled. All recession defects without loss of ICAL (ID-CAL) (RT1) and with an amount of ID-CAL equal or smaller to the buccal attachment loss (RT2), located at upper and lower anterior teeth were treated with CAF+CTG. IPH, LPH, AERSA and ICAL parameters were analysed for possible correlation with CRC after 6 months. The CRC was 86.7% for RT1, 74.2% for RT2 groups. The ROC analyses revealed acceptable cut-off points for baseline AERSA, IPH and LPH for achieving CRC. The results of logistic regression analyses showed that having baseline AERSA≥19 mm(2) (OR:23.7), IPH lower ≤1 mm (OR:97.3) and belonging to RT2 group (OR:15.0) were found to be independent risk factors related with not achieving final CRC. This study indicates that AERSA and IPH may be used to predict the final CRC outcomes in RT1 and RT2 defects treated with CAF+CTG.
