Description

<p>Objectives : Patients with eating disorders may have numerous dental caries and intraoral diseases such as dental erosion. The aims of this study were to investigate the experience of dental caries in patients with eating disorders and to elucidate factors affecting dental caries. Subjects : The study population included 87 patients with eating disorders (86 women, 1 man ; mean age, 31.6 years) who visited our clinical center of psychosomatic dentistry, a psychosomatic internal medicine department, or were hospitalized at a psychiatric hospital. Methods : Experiences of dental caries were assessed by oral examination using the Decayed, Missing, and Filled Teeth (DMFT) index. Patients were then categorized into a group with higher DMFT index scores (high group, n=63) or lower DMFT index scores (low group, n=23) based on the results of a 2011 survey of dental diseases. One patient whose DMFT index score was the same as the average score determined in the survey of dental diseases was excluded. Intraoral status, daily habits, and other parameters were compared between the two groups using the Student’s t-test and chi-square test. Results : No significant differences were found between the two groups in eating disorder duration, frequency of tooth brushing, or amount of residual plaque. However, the prevalence rates for bulimia, self-induced vomiting, and daily consumption of sugar-sweetened foods were significantly higher in the high group than in the low group (p<0.05, p<0.01, and p<0.01, respectively). Patients in the high group also had significantly more severe tooth erosion than did patients in the low group (p<0.01). Conclusions : Dental caries experiences in patients with eating disorders were more strongly associated with eating disorders symptoms than lack of daily dental care. In addition to providing patients with eating disorders with ordinary oral hygiene instruction, it may be necessary to monitor eating disorders symptoms and provide treatment in close cooperation with other medical professionals.</p>
