EVALUATION OF THE EFFECT OF SURGICAL EXPERIENCE LEVEL ON THE SUCCESS OF THE CORONALLY ADVANCED FLAP (CAF) TECHNIQUE.

The purpose of this study was to investigate the effects of experience level on the clinical and esthetic results of coronally advanced flap (CAF) surgery. A postgraduate student's first 40 CAF operations in the periodontology residency program were followed. The Miller Class I gingival recessions were divided into four chronologic groups (n = 10 in each). Clinical and esthetic evaluations were performed at baseline and after 6 months. The results of chronologic intervals were statistically compared. While the overall mean root coverage (RC) percentage was 73.6% and the complete RC was 60%, the mean RC percentages of the groups, respectively, were 45%, 55%, 86%, and 95%, showing that the mean and complete RC percentage increased as the experience level increased (P < .05). Similarly, as the experience level increased, closure of the gingival recession depth and width and esthetic scores increased, while the surgical time decreased significantly (P < .05). Complications were observed in three patients during the first interval and in two patients during the second interval, while no complications were observed in the other groups. This study showed that experience level can significantly affect the clinical and esthetic outcomes, operative time, and complication rates of CAF surgery. All education programs should determine how many of each surgical procedure residents must perform before they are considered experienced or expert surgeons who can work independently and predictably achie vesafe, acceptable outcomes.
