Single Flap Approach Versus Conventional Flap in the Treatment of Intrabony Defects: A 6-Month Clinico Radiological Study

Abstract

Abstract Introduction: The comparison of single-flap approach (SFA) and conventional flap (CF) techniques in the treatment of intrabony defects is a significant area of periodontal research. This clinical-radiological study evaluates the effectiveness of these methods over a 6-month period. SFA involves minimal surgical intervention, promoting faster healing and reduced patient discomfort. Conversely, CF is a traditional method with broader exposure to the surgical site for more extensive cleaning and repair. This study aims to provide insights into the relative advantages and clinical outcomes associated with each approach, contributing to evidence-based periodontal therapy practices. Materials and Methods: Thirty sites with chronic/aggressive periodontitis were selected for the present study. Phase I therapy was performed and evaluated after 4 weeks. Clinical parameters such as plaque and gingival index and probing pocket depth (PPD) were measured at baseline and 6 months postoperatively. The mean defect fills and percentage defect fill were calculated with the help of cone-beam computed tomography at baseline and 6 months postoperatively. The subjects were divided into two equal groups with the help of a coin toss. The Group I (test sites) underwent an SFA, whereas the Group II (control) site underwent conventional surgical procedures. Results: The PPD in both groups was reduced over a 6-month post-operative period. The mean defect size and percentage of defect fill between baseline and 6 months postoperatively in both groups were statistically significant. Conclusion: The single-flap approach and the CF are equally effective in treating periodontal intrabony defects.
