Periapical radiographs of teeth requiring treatment were obtained prior to the initiation of restorative procedures. A Parkell Pulp vitality tester (Parkell Electronics DN, Farmingdale, NY, USA) has been used to record the teeth vitality test results. All restorations were acquired by one operator, and the primary investigator supervised all clinical processes. Depending on the accessibility, a Rubber dam was placed either prior to the surgical procedure or after the cavity was opened following anesthesia. The carious tissue and all undermined enamel were removed to allow access to the cavity using a high-speed carbide bur #245 (1.6 mm length and 0.8 mm diameter) with sufficient air/water spray (Komet dental Gebr brasseler GmbH and Co lemgo, Germany). Using a selective caries removal, deep caries were removed using a hand excavator and low-speed tungsten carbide burs. The excavation of the preparation floor was primarily guided by probing with an explorer and observing the dentin’s color. The adhesive preparation design adhered to minimally invasive dentistry principles. Each patient received two restorations under similar clinical conditions.Futurabond M (Voco), a universal dual-cure self-etching adhesive, was administered to all preparations following the manufacturer’s guidelines. The adhesive was applied actively for 20 s, followed by a soft air blow for 5 s and light curing for 10 s. The restoration procedures involved the utilization of a separation ring, a pre-contoured metallic sectional matrix, and a wooden wedge (Unimatrix System, TDV, Pomerode, SC, Brazil). A periodontal probe was utilized to assess the cavity depth. A universal shade was applied in a single bulk increment when the preparation was up to four millimeters deep. The composite was cured with light for the 20s after shaping. Carbon paper was used to make a post-occlusal adjustment, while dental floss and interproximal radiographs were utilized to assess the quality of the cervical adaptation and interproximal contacts. The restorations were finished with fine-grain diamond burs (KG Sorensen, S˜ao Paulo, SP, Brazil) under water cooling. Abrasive strips (3 M ESPE / St. Paul, MN) were utilized to remove any excess at the proximal surface. Fine and super-fine diamond points with abrasive rubber points (Dimanto, Voco) were made at the proximal surfaces with fine-grained strips during the same appointment immediately following the restoration procedures.
