Introduction: The aim of this study was to investigate the effect of two processes (cycles of incubator drying and sectioning with a diamond blade) on the weight of different anatomical types of simulation teeth used in the proposed assessment process in a preclinical dental teaching program. Materials and Methods: Sixty-eight new unprepared reference plastic Columbia teeth of 17 different anatomical types were cleaned, dried, and sectioned with a diamond blade and the change in weight recorded. Four hundred and four teeth including 210 teeth prepared for a variety of different crown preparations, 68 reference teeth of 17 different anatomical types and 68 sectioned teeth of 17 different anatomical types were cleaned, dried, and subjected to three incubator cycles of 60°C for 24 h. The change in weight was recorded before and after each cycle. Results: The average percentage of tooth lost through sectioning for all teeth was 2.7% which varied from 2.3% in smaller diameter teeth to 3.1% in larger diameter teeth. There was no significantly different percentage tooth loss between the different anatomical tooth types (global P = 1.0000). The average loss of tooth weight over the duration of all incubator cycles for all teeth was 1.64%. When controlled for clustering, there was no statistically significant difference in weight across the time periods within each of the tooth groups. Conclusion: The testing conditions employed in this study did not produce a statistically significant loss in tooth weight and showed initial promise in the proposed protocol of assessment of simulation teeth on a large scale.
