2.  Intraclass correlation coefficient (rho) for agreement
among dentists’ recs for restorative tx due to caries, for teeth
grouped by restoration and caries status
n Just as was suggested for the 13 teeth in Table 1
n some of the lack of agreement may be due to differences in
attribution of reasons to recommend treatment
n Rather than difference in decisions to recommend tx
n When parallel analyses were performed to determine extent of
agreement for treatment recommended for any reason
n the rho values were approximately 0.10 higher for each tooth
status category except unrestored carious teeth
n Differences in extents of agreement
 as well as the deterioration caused by the presence of a
restoration
 suggest that variation among practitioners is elevated in
assessments of the caries status of restoration margins
