A total of 318 teeth in 81 subjects (35 men and 46 women) were selected, totaling 75 participants with four restorations and six participants with three restorations. The restorations were randomized in blocks of six experimental groups (n=53). During the preparation of the cavities, 12 teeth had to be removed from the study because of pulp exposure and 11 teeth because the patient refused to continue participating in the clinical trial; thus, the final number of restorations performed was 295, distributed among the six research groups. All subjects attended the control visit after one week. One subject did not attend to recall at the six-month evaluation; two subjects, to the 12-month, and eight subjects to the 24-month ( The restorative procedures were implemented exactly as planned, and no modification was conducted. All baseline details regarding the research subjects and characteristics of the restored cavities were described in
