Introduction. Adult disabled people, including mentally handicapped ones, constitute a very serious medical problem in both general and specialist medical care, including dentistry. Dental treatment under general anesthesia is the most recommended for this group of patients.Aim. The aim of this study was to analyze the structure of a group of adult disabled patients treated dentally under general anesthesia.Material and methods. The study was conducted among 147 disabled people, 61 females and 86 males aged 18-56 (the average age − 26.69) from the Lubelskie Voivodeship, qualified for dental treatment under general anesthesia. The survey was basedon interviews with the family members or social workers. The questionnaire included the information concerning general diseases, age, gender, place of residence and the kind of care (family or social welfare institutions). Special attention was paid to the previous dental treatment performed in outpatient clinics or under general anesthesia.Results. The study involved a group of 147 people, including 58.50% males and 41.50% females. The average age of the patients was 26.69 ± 6.41 years (ranged from18 to 56). The patients from a big city accounted for 40.14%, 23.13% of the subjects came from a small town, and 36.73% of the people came from the village. The largest group of patients included people with mental disabilities − 54.43%. Most people (87.76%) lived with their family, while 12.24% were the residents of social welfare institutions. The analysis of the data reveals that for 89.80% of patients, it was their first dental treatment under general anesthesia, and for 10.20%, a subsequent one. Studies have shown that early treatment in outpatient clinics wasperformed in only 27.21% of treated people, while 72.79% have never been treated in a dental surgery.Conclusions. Mentally handicapped people were the largest group of patients treated dentally under general anesthesia. Patients living in the urban areas and under the care of families were more often treated dentally under general anesthesia. Because of the lack of cooperation between disabled patients and the dentist, the complete dental treatment under general anesthesia is the most effective therapy. Adult disabled patients require special dental care.
