Summary: The paper analyzes a group of 32 adult non-cooperating patients who in 1997–1999 had dental treatment under general anaesthesia. In the majority mental patients were involved, people with mental affections and two subjects with an uncontrollable vomiting reflex. The majority were in domiciliary care. The patients were examined and had a single treatment under general anaesthesia with orotracheal intubation. The authors assessed the availability of this special care for untreatable patients, the dental cariosity using the DMF index, the mean period of treatment, the number of operations, materials used, and types of caries according to Black’s classification. The distance covered on account of treatment in 13 subjects (40.6 %) was more than 60 km. Collaboration with parents and general practitioners did not have the desirable standard. The mean DMF value was 16.84 which confirms a high cariosity. The patients were treated on average for one hour and 35 minutes. During this period 5.97 operations were made incl. 2.13 extractions and 3.84 fillings. From the total number of 123 fillings the majority belonged into the Black class V – 38 (30.85 %) and into class I – 32(26.02 %), followed by 29 (23.58 %) class III, 13 (10.57 %) class IV and fewest 11 (8.94 %) in class II. A large proportion of cavities on the dental neck was due to poor hygiene and poor dietary habits. The most frequently used material was amalgam in 61 cases (49.59 %), compomer in 40 cases (35.52 %) and glass ionomeric cement in 22 patients (17.89 %). In untreatable patients dental treatment under general anaesthesia is frequently the only solution. Greater availability of this special care and motivation of guardians cold ensure regular dental treatment of problem subjects and would help to preserve their dental function to more advanced age.
