The reasons for the treatment under general anaesthesia were serious systemic diseases or anxiety. The study results demonstrated high caries experience in non-cooperative and handicapped children. DMFT index in this group was 4.29, with D = 3.82 (81%), F = 0.29 (6.8%), E = 0.18(4.2%), RI value was 47.37%. All the obtained values are very high in comparison to the data reported for a common corresponding population. Especially high data were found in extracted teeth E = 0.18 while in the corresponding children population the value of 0.01 was reported.
