Oral health status of individuals with eating disorders: Systematic review and meta-analysis
Abstract
OBJECTIVES: This systematic review and meta-analysis evaluates the oral health status of individuals diagnosed with eating disorders (EDs) compared to healthy controls.
DATA & SOURCES: Electronic database search was conducted in five databases. Two independent reviewers carried out screening, data extraction, risk of bias assessment, sensitivity analysis, subgroup analysis (by type of eating disorder), and certainty of evidence grading with Grading of Recommendations, Assessment, Development, and Evaluation (GRADE). Assessed oral health outcomes included dental caries, erosion, oral hygiene, periodontal status, salivary flow, pH and composition, myofascial pain, bruxism, malocclusion, oral lesions, dentine hypersensitivity, and oral health-related quality of life (OHRQoL).
STUDY SELECTION: The literature search yielded 2,322 articles. Thirty-three articles were included in the present review.
CONCLUSION: Individuals with EDs had poorer oral health outcomes compared to healthy controls, although the effect estimates are uncertain due to very low certainty of evidence. Dental caries and gingival inflammation severity, and prevalence of dental erosion, myofascial pain, malocclusion, oral lesions, and dentine sensitivity were higher amongst individuals with EDs compared to healthy controls. They also had lower salivary flow and pH, which are risk factors for oral diseases. No significant difference in bruxism was noted and inconclusive results were obtained for oral hygiene and…
