About

Atraumatic Restorative Treatment (ART) has become an accepted dental restoration treatment in many developing countries. Because, ART is intended to be operated in molars, and about 10% of all carious lesion by an age of 18 years appear in anterior teeth in Gambia, it was the aim of this study to clinically evaluate a modified ART restoration technique for anterior teeth as the traditional treatment approach did not show satisfying clinical results.

Full description

Atraumatic Restorative Treatment (ART) has become an evidence-based treatment in class I caries cavities for countries with developing dental infrastructure. Though epidemiological data also demonstrate restorative treatment needs in anterior teeth in several African countries, scientific evidence for ART in this application appeared so far unrewarding. Consequently, many carious teeth remain untreated or are scheduled for extraction. In deciduous teeth, class III and IV ART presented 86% failures due to partial or complete loss already within the first year, and longitudinal data in the permanent dentition are rare. Survival rates of 71% after three years, and of 68% after six years in the same study cohort were reported from Brazil.

Basically, ART appears to be an interesting treatment approach as it combines a manual cavity preparation technique with the use of a glass-ionomer cement as an adhesive and fluoride releasing restoration material. Biomechanical stress, however, is above-average in class IV restorations when intending to reconstruct the incisal edge with glass-ionomer cement resulting in reported high rates of restoration fractures or loss. It was therefore the aim to evaluate the clinical effectiveness of a modified ART class IV restoration technique in a clinical study. These data are to be compared with an historical control (original ART class IV anatomical structure rebuilding restorations). Historical control data will be retrieved from "Jordan RA, Gaengler P, Markovic L, Zimmer S: Performance of Atraumatic Restorative Tratment (ART) depending on operator-experience. J Public Health Dent 2010; 70: 176-80."
