Clinical evaluation of the ART approach and materials in peri-urban farm schools of the Johannesburg area.

In this study, 1,325 school children from 7 farm schools were examined. Their mean age (+/- SD) was 10.5 +/- 3.0 (range 6-11) years. At baseline, the mean DMFT score was 1.1 +/- 1.7 and 36.4% of the children had caries. The prevalence of fluorosis among the children was 12.6%. Curative treatment was offered to all the children. A total of 113 children (8.5%) with one-surface cavities on permanent teeth and without fluorosis were treated using the atraumatic restorative treatment (ART) approach. A total number of 163 cavities were included in the study, of which 82 were treated with Fuji IX glass-ionomer cement and 81 with Ketac-MOLAR (hand mix). One year after treatment, restoration and sealant parts of ART fillings were examined. Caries status was also determined. The placing of the ART fillings and their evaluation were performed by different practitioners. A total number of 108 restorations (58 with Fuji IX, 50 with Ketac-MOLAR) were evaluated. Results of ART fillings showed a survival rate of 93.1% with Fuji and 94.0% with Ketac-MOLAR. Retention of the sealant parts of ART fillings was observed in 81% of restorations with Fuji IX and 76% with Ketac-MOLAR, not connected to the filled cavity. Caries was absent on all teeth restored with Fuji IX and noted in only one tooth restored with Ketac-MOLAR, not connected to the filled cavity. The retention rate after a 12-month period was acceptable and ART approach proved to be an appropriate technique for restoring teeth in this population group. There were no statistically significant differences between the survival rates of the two glass-ionomer restorative materials (P > 0.05).
