Non-carious cervical lesions associated with gingival recessions: a decision-making process.

BACKGROUND: A method to predetermine the maximum root coverage level (MRC) was recently demonstrated to be reliable in predicting the position of the soft tissue margin after root coverage surgery. The aim of the present study is to suggest a decision-making process for treating non-carious cervical lesions (NCCLs) associated with gingival recessions based upon the topographic relationship between the MRC and NCCL and to assess patient and independent-periodontist esthetic evaluations. METHODS: Five treatments were performed in 94 patients with NCCLs associated with a single gingival recession: 1) coronally advanced flap (CAF); 2) bilaminar procedure; 3) coronal odontoplasty plus restoration plus root odontoplasty plus CAF; 4) restoration plus CAF; and 5) restorative therapy. Clinical and esthetic evaluations made by the patient and an independent periodontist were done 1 year after treatments. RESULTS: The satisfaction of the patient and periodontist with esthetics was very high in all NCCL treatments and Miller Class gingival recessions. The patient satisfaction and evaluation of root coverage and the periodontist evaluation of root coverage were statistically correlated with color-match evaluations and not with the amount of root coverage clinically achieved in each patient. CONCLUSION: The proposed approaches provided good esthetic appearance and correct emergence profile for the great majority of NCCLs associated with gingival recessions
