Background: The root coverage esthetic score (RES) was published in 2009 as an esthetic scoring system to measure visible final outcomes of root coverage procedures performed on Miller I and II recession defects. The aim of this study was to evaluate the intra-examiner, intra-group, and inter-examiner reliability of the RES when used among periodontal faculty, post-graduate students in periodontology, and pre-doctoral DMD students when using the RES at Tufts University School of Dental Medicine (TUSDM).
Methods: Thirty-three participants (12 second-year DMD students, 11 periodontal residents, and 10 faculty members) were assembled to evaluate 25 baseline and 6-month post-treatment outcomes of mucogingival surgeries using the RES.
