Surgical protocol Under local anesthesia, an intrasulcular incision was made with a 15C surgical blade on the buccal side of the involved tooth that extended to dissect the mesiobuccal aspect and distobuccal aspect of the adjacent papillae, horizontally, leaving the gingival margin of the adjacent teeth intact [ Figure s 2a and 3a]. From the mesial and distal ends of the horizontal incision, two releasing incisions were made obliquely. Using a Molt’s periosteal elevator, a split‑full‑split‑thickness flap was raised [ F igures 2b and 3b]. To facilitate the release residual muscle tension and the passive coronal displacement of the flap, a mesiodistal and apical dissection parallel to the vestibular lining mucosa was performed. De‑epithelialization of the papillae adjacent to the involved tooth was done. The previous unexposed root surface was planned thoroughly to the marginal bony crest and irrigated thoroughly with normal saline. For control site, the flap was coronally advanced without tension and suturing was done using polyvicryl 4‑0 resorbable suture [ Figure 2c]. For the test site, before suturing, the collagen membrane was trimmed with a curved cut in the area of the CEJ and was placed over the root or bone, coronal to the CEJ, extending at least to a distance of 2–3 mm beyond the bony margin [ Figure s 3c]. The membrane [figure 3f] was placed securely in position with a resorbable suture, the flap was passively repositioned coronally with sling suture, and the knot was tied securely. To close the wound of the releasing incisions beyond the mucogingival junction, additional lateral sutures were placed [ Figure 3d]. Periodontal dressings were given in both sites. Postsurgical protocol At 14 days postoperatively, removal of sutures and periodontal dressing were done. Recall for patients was scheduled for further routine checkup which was kept at 1 and 2 weeks, 1, 3, 6, and 9 months postoperatively. All the postoperative clinical measurements were done at 9 months postsurgery [ F igures 2d and 3e for control and test groups, respectively]. RESULTS The surgical procedures were uneventful, and all patients experienced no complications postoperatively, and complied with the study protocol.

Kapare, et al .: Resorbable membrane in recession coverage Journal of Indian Society of Periodontology - Volume XX, Issue XX, Month 2017 3 Recession depth At baseline, the mean RD for the control group was 2.67 ± 0.816, which was reduced to 1.13 ± 0.352 at 9 months with respect to baseline, showing reduction of 1.54 ± 0.46 mm that was statistically significant ( P < 0.0001) [Table 1 and Figure 1a]. The mean RD for the test group at baseline was 2.73 ± 0.594, which was reduced to 1.13 ± 0.516 with respect to baseline, showing reduction of 1.60 ± 0.07 mm that was statistically significant ( P < 0.0001) [Table 1 and Figure 1a]. The difference in the mean RD with the test and control groups was 0.06 ± 0.26 which was not statistically significant ( P > 0.05) [Table 2 and Figure 1a].

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    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.
