Abstract: Background: The aim of this randomized clinical trial was to evaluate the treatment of gingival recession associated with non-carious cervical lesions by a coronally advanced flap alone (CAF) or in combination with a resin-modified glass ionomer restoration (CAF+R). Methods: Nineteen subjects with bilateral Miller Class I buccal gingival recessions associated with non-carious cervical lesions were selected. The recessions were assigned randomly to receive CAF or CAF+R. Bleeding on probing (BOP), probing depth (PD), relative gingival recession (RGR), clinical attachment level (CAL), non-carious cervical lesion height (CLH), and dentin sensitivity (DS) were measured at baseline; 45 days; and 2, 3, and 6 months postoperatively. Keratinized tissue width (KTW) and keratinized tissue thickness (KTT) were measured at baseline and 6 months. The height of the non-carious cervical lesion located on the root and crown were estimated, allowing calculation of root coverage. Results: Both groups showed statistically significant gains in CAL and soft tissue coverage. The differences between groups were not statistically significant for BOP, PD, RGR, CAL, KTW, and KTT after 6 months. The percentages of CLH covered were 56.14% +/- 11.74% for CAF+R and 59.78% +/- 11.11% for CAF (P >0.05). The root and crown surfaces affected by the non-carious cervical lesion were 1.67 +/- 0.31 mm and 0.96 +/- 0.29 mm, respectively, for CAF+R and 1.59 +/- 0.37 mm and 1.01 +/- 0.33 mm, respectively, for CAF. The estimated root coverage was 88.02% +/- 19.45% for CAF+R and 97.48% +/- 15.36% for CAF (P>0.05). CAF+R reduced DS significantly compared to CAF (P<0.05). Conclusions: Both procedures provided similar soft tissue coverage after 6 months. Despite the fact that a greater reduction in DS was observed after CAF+R, longitudinal observations are necessary to confirm these results.
