 en The operator as a factor of success in ART restorations
da Franca, Carolina; Colares, Viviane & van Amerongen, Evert


Aim: To evaluate the operator as a factor of success in atraumatic restorative treatment (ART) restorations.
Methods: This was a clinical intervention study. The sample consisted of 271 glass-ionomer cement (Ketac Molar, 3M ESPE) restorations placed in 246 children aged 5 to 9 years attending public schools in Recife, Brazil. The operators were two senior undergraduate dental students and one dentist, classified as 'inexperienced' and `experienced', respectively. Two groups of children were formed: one treated by the undergraduate students and the other treated by the dentist. The evaluation of the restorations took place at 1, 4 and 12 months by three senior undergraduate dental students.
Results:Comparing the operators, a significant difference was found in class II cavities filled by students, who had a lower rate of success. There were no differences between the dentist and undergraduate dental students for class I cavities.
Conclusions: The operator's experience makes a difference in the success rate of more complex ART restorations when an experienced operator receives the same training as an inexperienced operator.
