AIM: To evaluate influence of two methods to avoid saliva contamination on the survival rate of atraumatic restorations in primary molars. 232 children, aged between 6-7 years, of both genders, were selected having one primary molar with a proximal dentine lesion. The children were randomly divided into two groups: a control group with class II ART restoration made using cotton rolls and an experimental group using rubber dam. The restorations were made and they were followed up every six months. After two years, the results were compilated and analyzed.
