The reliability of a newly developed tooth wear grading system was assessed both clinically and on dental casts by two observers using 20 participants. The reliability of clinical occlusal/incisal tooth wear grading was fair-to-good to excellent, while that of most of the clinical nonocclusal/nonincisal grades was at least fair-to-good. Dental cast assessment frequently yielded poor reliabilities, especially for nonocclusal/nonincisal surfaces. Hence, occlusal/incisal wear could be graded more reliably than nonocclusal/nonincisal wear, while the clinical assessment of tooth wear was more reliable than the grading of dental casts.
两名观察者使用20名参与者，在临床上和牙模上评估了一种新开发的牙齿磨损分级系统的可靠性。临床咬合/切端牙齿磨损分级的可靠性为中等到良好至优秀，而大多数临床非咬合/非切端分级的可靠性至少为中等到良好。牙模评估的可靠性常常较差，尤其是对于非咬合/非切端表面。因此，咬合/切端磨损的分级比非咬合/非切端磨损更可靠，而牙齿磨损的临床评估比牙模分级更可靠。
