Purpose: This systematic review aims to comprehensively assess the prevalence, extent, severity, and distribution of gingival recession (GR) among university students. Recognizing that GR represents a significant periodontal concern with aesthetic and functional consequences, this review focuses on a young demographic that is underrepresented in epidemiological surveys.
Materials and Methods: Following the PRISMA guidelines and a pre-registered protocol, a structured search strategy was designed and executed across PubMed, Web of Science, Cochrane, and EBSCO databases, targeting studies published over the last 20 years. Eligibility was defined using the PICO framework: Population: university students; Intervention/Exposure: presence of GR; Comparison: absence of GR; Outcome: prevalence rates. The Joanna Briggs Institute (JBI) critical appraisal checklists were used to assess methodological quality and risk of bias across various study designs, including cross-sectional, cohort, case-control, and randomized controlled trials.
Results: Out of 299 initially identified articles, nine met the inclusion criteria, encompassing a total of 1,619 participants. The design of the included studies revealed considerable heterogeneity in sampling, measurement methods, and reported prevalence, which ranged widely from 29.4% to 82.6%. Risk factors linked to GR included age, gender, oral hygiene practices, brushing technique and force, occlusal interferences, and anatomical factors.
Conclusion: This systematic review demonstrates a high prevalence of gingival recession among university students, underscoring the importance of targeted preventive strategies and educational interventions in this population. Future well-designed longitudinal studies are needed to clarify causality and inform tailored prevention programs.
