Abstract

Root coverage surgery can be performed in patients with gingival recession to cover the exposed root aiming to control hypersensitivity and promotes better aesthetic. Optical magnification has been proposed as a refinement in this surgical technique to increase root coverage. This approach may lead to enhanced soft tissue stability, less post-operative discomfort, better predictability and esthetic appearance. Aim: This systematic review aimed to evaluate the effectiveness of magnification on root coverage surgery when compared to procedures performed without magnification. Methods: Randomized controlled trials with a follow-up of at least 6 months that compared surgeries for root coverage performed under optic magnification versus conventional (macro) root coverage surgery were screened. The primary outcome was mean root coverage (mm) (MRC) and secondary outcomes were percentage of root coverage (PRC) and complete root coverage (CRC). Results: Of 569 papers relevant to this review, seven were included. Meta-analysis showed that the use of magnification may favor greater PRC (7.38%, 95% CI 3.66-11.09). Conclusion: Magnification can increase PRC in root coverage surgeries. More randomized trials with the use of magnification may be necessary to verify if this benefit is clinically relevant, in order to justify the use of this device.

Highlights

Gingival recession (GR) is the apical displacement of the gingival margin, which results in the exposure of the root surface[1,2]
Summary measures and Synthesis of results Summary measures were calculated as difference in means for MRC and PRC, gain of KTW and CAL change, and as risk ratio for CRC, using random-effects models
All meta-analyses were conducted with a software package (Review Manager Software, version 5.3, The Nordic Cochrane Centre, The Cochrane Collaboration, Copenhagen, Denmark)

Summary

Introduction

Gingival recession (GR) is the apical displacement of the gingival margin, which results in the exposure of the root surface[1,2]. It is a frequent condition, which affects a significant percentage of subjects and teeth[3]. It has been associated with older age, male gender[4], smoking exposure[5,6], higher education[3,5,7,8], poor self-reported oral hygiene[5,6,9,10], higher percentage of sites with gingivitis[6], regular dental visits, history of periodontal treatment and presence of calculus[3,5,7,8]. Several techniques have been proposed as root coverage procedures[11,16,17], which result in correction of gingival deformities, position and/ or amount of keratinized tissue[14,15]
