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

Background 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 ). Material & Methods A total of 122 patients with one isolated gingival recession were enrolled. All recession defects without loss of ICAL ( ID ‐ CAL ) ( RT 1) and with an amount of ID ‐ CAL equal or smaller to the buccal attachment loss ( RT 2), 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. Results The CRC was 86.7% for RT 1, 74.2% for RT 2 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 RT 2 group ( OR :15.0) were found to be independent risk factors related with not achieving final CRC . Conclusion This study indicates that AERSA and IPH may be used to predict the final CRC outcomes in RT 1 and RT 2 defects treated with CAF + CTG .
