Aims:
The aim was to compare the recession coverage outcomes when done macrosurgically and microsurgically.
Background:
Increasing interest in esthetics and the related problems such as hypersensitivity and root caries have favored the development of many root coverage procedures. Recession coverage up to a certain extent has solved these problems, but these procedures need good maintenance after the surgery for long-term benefits. With increasing advances in the field of recession coverage, microscope has added another dimension in undertaking the surgical procedure.
Materials And Methods:
Thirty Miller's Class I and II recession were treated using the sub-epithelial connective tissue graft from the palate. In 15 sites, the graft was placed at the recipient site with unaided eye (Group A) and in other 15 sites the graft was placed using surgical microscope (Group B). Clinical evaluation was done at baseline, 12 weeks and 24 weeks postoperatively using plaque index, gingival index, vertical recession (VR), probing depth, clinical attachment level (CAL), width of attached gingiva, papilla height (PH) and width, malalignment index (MI) and esthetic appearance.
Statistical Analysis Used:
Paired and unpaired Student's t-test along with Wilcoxon Z-test were used to analyze the results and probability of P < 0.05 were accepted to reject the null hypothesis. Pearson correlation was used to correlate two parameters such as VR and CAL and MI and VR.
Results:
Both the techniques demonstrated predictable mean root coverage (Group A 61.78% and Group B 67.58%) at 6 months postsurgery. CAL gain was slightly better in Group B patients when compared to Group A patients. A moderate positive correlation for Group A while a mild correlation in Group B was seen between the MI and VR.
Conclusion:
The use of the microscope enhances the results, but obtaining an expertise in using needs a lot of practice. The periodontal healing by both techniques should be evaluated histologically.
