To explore the influence of inter-dental tissues and root surface condition on complete root coverage following surgical treatment of gingival recessions.


Three hundred and eighty-six single recessions treated over 28 years were assessed. Patient-level and periodontal variables, presence/loss of inter-dental tissues, and presence/absence of non-carious cervical lesions (NCCLs) were recorded. Root coverage was assessed 1-year post-surgery. Multilevel analysis was performed to identify predictors of CRC.


Based on type of root coverage procedure four patient groups were created free gingival graft (FGG) (n = 116), coronally advanced flap (CAF) (n = 107), CAF+connective tissue graft (CTG) (n = 131), and guided tissue regeneration (GTR) (n = 32). Percentages of complete root coverage (CRC) were 18.1% for FGG, 35.5% for CAF, 35.1% for CAF+CTG, and 18.8% for GTR. There was an OR = 0.26 (p < 0.0001) of achieving CRC in cases with loss of inter-dental tissue compared with cases with no inter-dental tissue loss. Similarly, cases with presence of NCCL showed an OR = 0.28 (p < 0.0001) of achieving CRC compared with cases without a NCCL. FGG achieved less CRC then CAF+CTG (p = 0.0012; OR = 0.32).


NCCLs, just like inter-dental tissue loss, are significant negative prognostic factors in achieving CRC following root coverage procedures.
