An observational study in Eating Disorder NOS, sponsored by Ondokuz Mayıs University. Completed at 1 site in Turkey (Türkiye). Open to participants aged 12 Years to 18 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-10-27.

Although numerous instruments are available to assess oral health-related quality of life (OHRQoL) in adults, there is a paucity of studies evaluating the impact of oral health on quality of life in children and adolescents. In Türkiye, no study has been conducted to assess oral health-related quality of life in patients with eating disorders.
The aim of this study is to evaluate and compare the oral health status of individuals diagnosed with eating disorders and healthy individuals without an eating disorder diagnosis using various clinical indices, as well as to assess oral health-related quality of life through questionnaires completed by both patients and their parents.
At the conclusion of the study, the treatment needs of the patients will be communicated to both the patients and their parents, and the patients will be referred to the departments of pediatric dentistry and other relevant specialties at a university hospital to receive the necessary dental treatments.
Eating disorders are serious psychiatric conditions associated with substantial morbidity and mortality, leading to significant impairments in somatic health and psychosocial functioning (1). Anorexia nervosa and bulimia nervosa are eating disorders characterized by an intense fear of weight gain, maladaptive weight control behaviors, and marked disturbances in body image (2). Because many of these complications can adversely affect quality of life and the overall management of eating disorders, it is essential to understand, monitor, and treat their secondary mental, systemic, and oral health-related effects (3).
Eating disorders are characterized by alterations in eating behaviors that may lead to deterioration in oral health and damage to dental hard tissues (4). However, the existing literature includes only a limited number of reports focusing on oral health outcomes in patients diagnosed with eating disorders at the age of 20 years (5,6). Oral diseases, such as dental caries and periodontal conditions, have physical, economic, social, and psychological consequences and may negatively affect oral function and overall quality of life (7).
Oral health-related quality of life (OHRQoL) refers to an individual's perception of the impact of oral health on daily life and encompasses the effects of oral conditions on functional capacity as well as emotional and social well-being (8). Previous studies have demonstrated a strong association between dental caries and OHRQoL in children (9). However, no studies conducted in Türkiye have evaluated OHRQoL in patients with eating disorders.
Therefore, by assessing the oral health status of patients with eating disorders using established oral health parameters reported in the literature and comparing OHRQoL outcomes with those of healthy controls, this study aims to contribute to the existing literature by providing a comparative evaluation of oral health status within the framework of OHRQoL in patients with eating disorders.

The study population consists of children and adolescents aged between 12 and 18 years. The population is divided into two groups: a study group and a control group.
The study group comprises children and adolescents diagnosed with eating disorders (anorexia nervosa and/or bulimia nervosa) according to DSM-5 criteria, who were referred to and followed at the Child and Adolescent Psychiatry Clinic of Ondokuz Mayıs University Faculty of Medicine.
The control group consists of physically and psychologically healthy children and adolescents without any diagnosis of eating disorders or other psychiatric disorders, who presented to the Faculty of Dentistry of Ondokuz Mayıs University.
Participants in both groups were selected within the 12-18 age range in accordance with the predefined inclusion and exclusion criteria. The study population includes only individuals for whom written informed consent was obtained from parents or legal guardians and assent was obtained from the children or a

What distinguishes this study from others is the nature of the control group and the fact that the specified scales are used together for the first time.The study group consists of children and adolescents diagnosed with eating disorders who were referred to the Child and Adolescent Psychiatry Clinic of Ondokuz Mayıs University Faculty of Medicine. The control group comprises physically and psychologically healthy children and adolescents who presented to the Faculty of Dentistry of Ondokuz Mayıs University. Participants in both groups will be selected within the age range of 12-18 years. All participating children, adolescents, and their legal guardians will be informed both verbally and in writing about the aim of the study, participation criteria, applied procedures, potential benefits, and possible risks. In addition, a questionnaire assessing sociodemographic characteristics, nutrition-related factors, dietary habits, and oral hygiene practices will be completed jointly by the ch

Oral Health-Related Quality of Life (OHRQoL)
The primary outcome measure of this study is the assessment of oral health-related quality of life in children and adolescents with eating disorders compared with healthy controls. Oral health-related quality of life will be evaluated using the Oral Health Impact Profile-14 (OHIP-14) questionnaire, and group comparisons will be performed based on total OHIP-14 scores. Higher OHIP-14 scores indicate increased severity of oral health problems and poorer quality of life.
