The aim of this investigation was to assess the operative response of a representative sample of Irish General Dental Practitioners of various times since qualification to carious lesions of varying extent in both approximal surfaces of a lower left first molar tooth. 82 General Dental practitioners participated. The dentists were asked to treat 2 manikin teeth for minimal caries on both approximal surfaces extending to the enamel dentine junction, 2 teeth for caries extending approximately to half the thickness of the dentine and 2 teeth for caries extending more than ¾ of the dentine thickness. Weight measurements were made of the tooth substance cut away. Mean volumes of tooth material removed ranged from 21 mm 3 for minimal caries to 76 mm 3 for the largest amount of caries. A two‐factor analysis of variance revealed that the type of cavity preparation the dentist used had a significant effect on the volume of tooth material removed for all three extents of caries. Time since graduation had a significant effect on the volume of tooth material removed for the least extent of caries, but not for the other categories of carious involvement.
