The ART approach using glass-ionomers in relation to global oral health care

摘要

Dental caries is the most prevalent non-communicable disease in the world. Its management in high-income countries over the last four decades has resulted in relatively low caries prevalence in child and adolescent populations. In low- and middle-income countries, caries management is virtually non-existent and this may lead to serious physical and mental complications, particularly in children. Toothache is predominantly treated by extracting the cavitated tooth. Absence of restorative oral care is partly due to the copying from high-income countries, of restorative treatment reliant on electrically driven equipment and often inappropriate for use in many low- and middle-income countries. Atraumatic Restorative Treatment (ART), which does not rely on electrically driven equipment, has yielded good results over the last two decades. ART uses hand instruments and high-viscosity glass-ionomers. Its introduction into public oral healthcare systems has been piloted in several countries. Initial short-term results show that the introduction of ART, using high-viscosity glass-ionomers, has increased the ratio of restorations to extractions. Moreover, the percentage of ART restorations in relation to the total number of restorations placed increased steeply after its introduction and has remained high. However, ART introduction faced a few barriers, the most important being high patient workloads and the absence of a constant supply of dental instruments and glass-ionomers. High-viscosity glass-ionomer has become an essential element in public oral healthcare systems, particularly in those operating inadequately.
