METHODS: This study was implemented in 1996 and 294 ART restorations were placed in 197 children aged 12-13 years by five assistant dentists in four schools. Standard ART procedures and instruments were used combined with a high-strength glass-ionomer restorative material. One examiner evaluated the restorations annually using the ART criteria while at 5 years an independent external examiner used US Public Health Service (USPHS) criteria. RESULTS: Fifty-eight per cent of the restorations were followed for 6 years. At the 6-year evaluation examination, 76% and 59% of the small and large restorations respectively were present and were without major wear or defect (P 0.05). CONCLUSION: The 6-year survival rate of the class I ART restorations in this study, especially the smaller ones, was satisfactory. This suggests that the ART approach can be used in the school setting to improve the oral health of large populations of underserved children
