Patients with eating disorders (EDs) often experience significant oral health issues, including dental erosion and burning tongue. Dental professionals should be aware of these oral symptoms as potential indicators of EDs during patient assessments.
Area of Science:
- Oral Health
- Psychiatry
- Dental Medicine
Background:
- Eating disorders (EDs) are complex psychiatric conditions with significant systemic health implications.
- Oral health complications are frequently observed in individuals with EDs, yet specific clinical indicators for early detection remain underexplored.
- Identifying oral health parameters that can alert dental professionals to potential EDs is crucial for timely intervention.
Purpose of the Study:
- To compare the oral health status of patients with EDs against sex- and age-matched controls.
- To identify self-reported and clinical parameters indicative of EDs for dental healthcare professionals.
- To assess the diagnostic accuracy of specific oral health indicators for EDs.
Main Methods:
- A case-control study involving 54 patients with EDs and matched controls.
- Participants completed questionnaires and underwent clinical dental examinations.
- Multivariate analysis was employed to identify significant associations between EDs and oral health parameters.
Main Results:
- ED patients exhibited significantly higher odds of dental problems (OR=4.1), burning tongue (OR=14.2), dry/cracked lips (OR=9.6), and dental erosion (OR=8.5).
- ED patients reported worse perceived oral health (OR=6.0) and had more dental erosion (OR=5.5) if engaging in vomiting/binge eating behaviors.
- Sensitivity and specificity for classifying ED patients using five key variables were 83% and 79%, respectively.
Conclusions:
- Oral health problems are prevalent in patients with EDs and warrant consideration in routine dental assessments.
- Specific oral manifestations like dental erosion and burning tongue can serve as potential warning signs for EDs.
- Integrating oral health screening into ED patient management can improve early detection and treatment outcomes.
