RESUMO
PURPOSE: To assess periodontal parameters of noncarious cervical lesions (NCCLs) restored with glass-ionomer cement (RM-GIC) and composite resin at baseline, three and six months. MATERIALS AND METHODS: Eighteen patients with bilateral lesions were included in the study. Lesions (1 mm in depth) were randomly restored with each type of restorative material. Probing depth (PD), relative gingival recession (rGR), relative clinical attachment level (rCAL), visible plaque index (VPI) and gingival bleeding index (GBI) were measured. RESULTS: No statistically significant differences were found when comparing within groups (p > 0.05). However, the intergroup analysis demonstrated a decrease in GR and rCAL gain for teeth restored with the resin-modified glass-ionomer cement (RM-GIC). CONCLUSION: Both materials behaved similarly when in close contact with periodontal tissues and did not influence periodontal parameters.
