Percentage of root coverage The mean percentage of root coverage for the control group was 56.22% ±10.22% and 58.33% ±12.19% for the test group. The difference between the percentages in the test and control groups did not reach any significance statistically ( P > 0.05) [Table 3 and Figure 1f]. DISCUSSION In patients with varying oral hygiene standards, gingival recession causes unpleasant esthetics and root sensitivity, hence the treatment of buccal gingival recession has become a regular routine. [7] There was a greatest potential for reduction in gingival recession and complete RC while using CAF technique or combined procedures as revealed by several systematic reviews and meta‑analyses. [2] Henceforth, till date, these are the treatments of choice. An effective perio‑plastic surgical treatment of choice for Miller’s Class I/II multiple recessions is the coronally placed flap with several patient benefits that include RC, esthetics, and predictable long‑term results. [8] The main goal and advantage of incorporating GTR to RC procedure is to achieve periodontal regeneration that results in new attachment rather than connective tissue repair. [9] The predominant protein found in alveolar bone and periodontal connective tissues is collagen. The main advantage of collagen when used as a GTR‑based RC procedure is its hemostatic function and apart from that, collagen has a chemotactic function for fibroblasts that aids in cellular migration and attachment to facilitate primary wound closure, an important requirement for successful GTR outcomes. [6] Considering the above‑mentioned facts, the aim of this randomized, controlled, split‑mouth clinical study was to evaluate the clinical outcome of RC in the treatment of Miller’s Class I and II recession defects in maxillary anteriors and premolars CAF with and without RCM (Novabone RCM TM , [Figure 3f]). [6] The CAF design used in this study was similar to that described by de Sanctis and Zucchelli that involved the use of vertical releasing incisions and a split‑full‑split‑thickness flap design. [10] A split‑full‑split‑thickness flap design includes the partial thickness of the surgical papillae that facilitates the nutritional exchanges between them and the underlying de‑epithelized anatomical papillae, and it also improved the blending (in terms of color and thickness) of the surgically treated area with respect to adjacent soft tissues; the periosteum in the central portion of the flap so as to maximize soft tissue thickness over the avascular root surface. To increase the predictability of achieving adequate coronal positioning and complete defect coverage, vertical incisions were used. In similar studies by Felipe et al ., [11] and Papageorgakopoulos et al ., [12] a CAF with releasing incisions was compared to an envelope flap without releasing incisions. The procedure with releasing incisions resulted in achieving a significantly greater percentage of defect coverage (95%) than the procedure without releasing incisions (78%).

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
