Clinical Performance of regular resin composite with bioactive technology and resin-modified glass-ionomer in restorations of cervical lesions of Abfraction: a randomized controlled clinical trial

INTERVENTION: Dental Restoration, Permanent Group Control: 50 Non‐carious cervical lesions of abfraction type will be restored with resin‐modified glass ionomer cement (Vitremer, 3M ESPE). Experimental group 1: 50 Non‐carious cervical lesions of abfraction type will be restored with regular composite resin (Beautifil II, Shofu). Experimental group 2: 50 Non‐carious cervical lesions of abfraction type will be restored with regular of low contraction composite resin (Beautifil II LS, Shofu). Experimental group 3: 50 Non‐carious cervical lesions of abfraction type will be restored with regular Bulk‐fill composite resin (Beautifil Bulk Restorative, Shofu). The restorations will be performed under relative isolation after prophylaxis of the teeth and beveling of the enamel margins. Procedure/surgery CONDITION: Tooth Wear Tooth Wear ; Tooth Wear PRIMARY OUTCOME: Evaluate the retention of restorations using the modified USPHS and FDI methods.; The restorations will be evaluated by two blind examiners and calibrated in the baseline periods (7 days), 6 months, 1, 3 and 5 years. SECONDARY OUTCOME: Assess color, marginal pigmentation, caries, wear, marginal adaptation of restorations using the modified USPHS and FDI methods. ; The restorations will be evaluated by two blind examiners and calibrated in the baseline periods (7 days), 6 months, 1, 3 and 5 years. Assess the level of postoperative sensitivity using the visual analogic scale (VAS). ; The postoperative sensivity will be evaluated by two blind examiners and calibrated in the baseline periods (7 days), 6 months, 1, 3 and 5 years. ; INCLUSION CRITERIA: Participants must be between 18 and 65 years of age; have good oral hygiene; absence of periodontal disease; have at least 20 teeth in occlusion and of these three or more teeth must present noncarious cervical lesions (NCL) of the abfraction type; the lesions should be approximately 2 mm deep.
