FEATHERSTONE2, 1 University Gr.T Popa, Iasi, Romania, 2 University of California, San Francisco, USA Objective: This analysis evaluates the reliability of the caries index of the number of decayed missing and filled tooth surfaces (DMFS) being used in an ongoing randomized clinical trial of caries management by risk assessment. Methods: Consenting English-speaking adult participants with current dental decay (1-7 lesions), no root caries, at least 16 teeth and no xerostomia were recruited from the UCSF dental clinics and surrounding fluoridated areas. Clinical examinations and questionnaires were administered in the dental clinics. A clinical examination with radiographs by a dentist-epidemiologist determined initial DMFS. 3 dentists and 1 dental student subsequently determined DMFS only from radiographs (xDMFS) without examination in 108 enrollees, with each having at least duplicate assessments. Intra- and inter-examiner reliability was assessed with intraclass correlations (ICC) using mixed effects regression models. Results: Intra-examiner reliability was very good for 2 dentists and 1 dental student (ICC³0.85) and good for 1 dentist (ICC=0.73). Inter-examiner reliability was very good (ICC=0.88) among dentists. Conclusions: Radiograph intra-examiner reliability was good to very good; inter-examiner reliability was very good, confirming the success of our examiner training and calibration.
