The influence of anorexia nervosa on oral health and related parameters potentially relevant to orthodontic treatment: a systematic review and meta-analysis
摘要
Information on the oral health of patients with anorexia nervosa remains not satisfactory. The aim of this systematic review is to evaluate oral health parameters in anorexic patients compared to healthy individuals. Furthermore, potential clinical implications for orthodontic treatment are discussed from an orthodontic perspective.
Materials and methodsElectronic databases were searched for case-control and controlled clinical trial studies on dentofacial manifestations in anorexic patients up to 2/2024. Study selection, data extraction and risk of bias assessment was done independently by two authors. Random-effects meta-analyses of mean differences (MDs) or relative risks (RRs) with their 95% confidence intervals (CIs) were conducted, followed by sensitivity analyses.
ResultsEleven out of 573 initially identified studies were included. They involved oral health analyses of general anorexic patients ≥ 12 years (mean age 18.4). The meta-analysis showed that anorexia nervosa was associated with a significantly increased caries experience (DMFT), plaque accumulation and gingival inflammation (BOP). PH and salivary flow rate were significantly altered in patients with anorexia nervosa, although no significant relationship between α-amylase levels and anorexia nervosa was demonstrated.
ConclusionsThese data enabled us to formulate modalities for anorexia-specific orthodontic treatments. Based on the results, patients with anorexia nervosa exhibit an increased risk of caries and gingival inflammatory signs.
Clinical relevanceThe systematic information on dentofacial manifestations obtained in this study should be considered to better manage the oral health of anorexia patients.
