Abstract

This systematic review aimed to identify, evaluate, and summarize the results of relevant studies on radicular prominence and its relationship with gingival recessions. This review was conducted according to the PRISMA (Preferred Reporting Reviews and Meta-Analysis) guidelines, and the focused PICO question was “In teeth with vestibular site-specific root or alveolar bone prominence, what are the chances that this will lead to gingival recession or difficulty in root coverage procedures, compared to teeth correctly positioned in the alveolar bone or without anatomical root prominence?”. A search was carried out on three databases: Embase, PubMed/MedLine, and Wiley Library. This initial search was complemented with manual research. It included any clinical study, such as a randomized clinical trial, controlled clinical trial, prospective/retrospective clinical study, case series, or case report, published in English from January 2012 to December 2023, which reported any involvement of the root/bone prominence approach. The exclusion criteria were clinical studies without report results/details of the case(s), studies based on questionnaires, editorial letters, any review, in vitro/in silica and animal studies, and interviews. The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement was applied for quality assessment. A total of 163 articles were found, but only three articles were included (k = 0.98). The included studies observed negative correlations when comparing the variables root prominence with linear root coverage, root surface area covered, and linear tissue thickness gain. It suggested a significant reduction in root coverage for prominences greater than 1 mm; therefore, relevant keratinized tissue gains can be achieved in gingival recession treatment after the application of the odontoplasty. The STROBE checklist evaluated 22 items, and all the included studies had a high-quality assessment (greater than 75%) with values greater than 85%. Then, it was not possible to draw conclusions due to the number of articles included, even though they had high-quality assessments. Otherwise, it is possible to suggest that the root prominence may impact gingival recession. Therefore, new and well-designed studies must be developed to establish a significant conclusion about this condition.
