Abstract

AIM: To explore the influence of interdental tissues and root surface condition on complete root coverage following surgical treatment of gingival recessions. METHODS: 386 single recessions treated over 28 years were assessed. Patient-level and periodontal variables, presence/loss of interdental tissues and presence/absence of non-carious cervical lesions (NCCLs) were recorded. Root coverage was assessed one-year post-surgery. Multilevel analysis was performed to identify predictors of CRC. RESULTS: 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-value<0.0001) of achieving CRC in cases with loss of interdental tissue compared to cases with no interdental tissue loss. Similarly, cases with presence of NCCL showed an OR = 0.28 (p-value <0.0001) of achieving CRC compared to cases without a NCCL. FGG achieved less CRC then CAF+CTG (p-value = 0.0012; OR = 0.32). CONCLUSIONS: NCCLs, just like interdental tissue loss, are significant negative prognostic factors in achieving CRC following root coverage procedures. This article is protected by copyright.
