A single, calibrated, and blinded examiner (REF) recorded all the variables in the UPV/EHU Dental Clinic (Spain).The location and the number of teeth for intervention were recorded and the following clinical variables were measured in millimeters using a periodontal probe (PCP-11, Hu-Friedy® Mfg. Co. LLC, Chicago, USA): gingival recession (REC), probing depth (PD), clinical attachment level (CAL = REC + PD), and keratinized gingiva width (KGW) were measured in the mid vestibular, gingival recession width (GRW) was measured horizontally at the level of the CEJ, and the distance from the contact point to the interdental papilla (PC-IP) of the tooth with recession was measured both mesially and distally. As non-carious cervical lesions (NCCLs) were not excluded in the present study, when the CEJ was not detectable, it was determined considering the interdental CEJ which was easily identified by elevating the interdental soft tissue with a probe [Intraoperatively, the characteristics of the CTG (length, width, and thickness) were collected, and after the intervention, the occurrence or absence of PsI was recorded and described.Finally, at follow-up examinations at 6 and 12 months, the FMPI and FMBI were collected for all teeth, while the other previously recorded variables were evaluated only for the treated recessions. In addition, the CRC (the number of treated recessions with REC = 0 mm) was recorded, and the CRC% (CRC × 100/number of recessions) and the MRC% (mean preoperative REC-mean postoperative REC/mean preoperative REC × 100) were calculated.The primary outcome was the percentage of mean root coverage (MRC%) and the secondary outcomes were the percentage of complete root coverage (CRC%), changes in the periodontal soft tissues variables, and the postsurgical incidences (PsI).
