Changes of the dental service delivered to patients with intellectual disability under general anaesthesia in Dental Polyclinic Split, Croatia, during the years 1985-2009.

People with intellectual disability (ID) usually have a poor quality of oral health, which include poor oral hygiene, untreated caries and high proportion of missing teeth. Due to their fear and repulsive attitude towards medical staff general anesthesia is often a useful method for dental treatment. One thousand and fifty four intellectual disability patients for the period of 1985-2009 who received dental treatment under general anesthesia in Dental Polyclinic Split, were included in the study. Patients were divided into five groups based upon the period when a specific dental treatment had been received. Each period was analyzed for the number of ID patients treated and the type of dental treatment. The results showed that the most services provided were 4006 fillings, followed by 3225 extracted teeth and finally 274 endodontic treatments. Significantly the lowest number of fillings and endodontic treatments were found among patients in group II (1990-1994), with significantly the highest number of extracted teeth. In Conclusion, the types of dental treatment have changed during twenty five years. Number of extracted teeth decreased while the number of fillings and endodontic treatment increased. However, dental status of people with intellectual disability should be improved with more restorative treatments and with better oral health prevention program.

Decreasing of residual alveolar ridge height in complete denture wearers. A five year follow up study.

The resorption of the residual alveolar ridges is a chronic and continuous process of bone remodeling. The aim of this study was to analyse the rate of residual ridge resorption at different sites in the both jaws in complete denture wearers, through a five-year period of denture wearing. Residual ridge changes were measured on successive lateral cephalograms at 5 measurement points of the maxilla and the mandible. The first lateral radiograph was obtained at the delivery of complete dentures. The second lateral cephalogram was obtained after five years of denture wearing. Measurements were performed using a calibrated grid. The results of this study showed the existence of a significant alveolar ridge resorption at all five measurement points of the maxilla and the mandible. The observed variables, such as body mass index and the night time denture wearing had no significant influence on the rate of residual alveolar ridge resorption (p > 0.05). The duration of edentulousness had a significant influence on the rate of residual ridge resorption with significantly higher amounts of alveolar bone height decrease in those patients who had lost the last remaining teeth more recently.
