Coverage of localized gingival recession using coronally advanced flap: A comparison between microsurgical and macrosurgical techniques
Abstract
Background: The aim of the present study was to compare the root coverage of localized gingival recession (GR) using modified coronally advanced flap (CAF) (Sanctis and Zucchelli's technique) and root conditioning 24% ethylenediaminetetraacetic acid (EDTA) when done under magnification and without magnification. Materials and Methods: A total of 20 sites were taken with Miller's Class I GR (10 in test and 10 in control). All clinical parameters were recorded at baseline, 1 month, and 3 months. CAF and root conditioning were done with 24% EDTA. Surgical procedure at test site was carried under magnification ×3.5 and at control site was done without magnification. Results: Plaque index, gingival index, clinical attachment level, probing depth, width of keratinized tissue (WKT), recession depth (RD), and recession width (RW) at baseline and 3 months were compared using Student's t- test. Mean WKT at baseline in control and test group was 4.22 ± 2.05 and 3.22 ± 1.09 which increased to 4.56 ± 1.59 and 4.50 ± 0.94, respectively, at 3 months. RD at baseline in control and test groups was 2.56 ± 0.53 and 2.67 ± 0.87 which reduced to 1.83 ± 0.71 and 1.22 ± 1.20, respectively. RW at baseline in control and test group was 3.56 ± 1.13 and 3.67 ± 0.50 which decreased to 3.06 ± 1.01 and 1.72 ± 1.39, respectively. All the clinical parameters were statistically not significant between control and test groups. Mean visual analog scale (VAS) at 7 days postoperatively in control and test groups was 1.78 ± 0.97 and 0.22 ± 0.44, respectively. The VAS scores were found to be significantly lower in the test group at both 3rd and 7th day postoperatively showing less pain in test group. Conclusion: Microsurgery offers less pain and enhanced outcomes when compared to traditional macrosurgery.
