This study represents an attempt to introduce a system for the longitudinal evaluation of the severity and the rate of progression of tooth wear. The material comprised a selected group of 10 males and 10 females, examined twice within an 18-month period. The subjects were predisposed to advanced occlusal wear and had a mean age of 32 years within the range of 16-56 years. Evaluation of occlusal wear was performed on a tooth-by-tooth basis, on study casts, using two ordinal scales, one for assessing the severity, and the other the progression of occlusal wear. The reliability of the scales was assessed by percentage inter-observer concordances. The sample exhibited higher occlusal wear scores in the incisor and canine regions compared to the posterior region. It was found that the overall progression in an 18-month follow-up period was slow. The inter-observer concordance in the evaluation of the severity of wear was 88%, and 91% in the progression of wear. Within the limitations of the described system, the scales may be utilized for determining the severity of occlusal wear and the rate of its deterioration in an individual's dentition. From a clinical standpoint, the need for future treatment may be based on such a evaluation of the progression of wear.
本研究旨在尝试引入一种用于纵向评估牙齿磨损严重程度和进展速率的系统。研究材料包括一组经过挑选的10名男性和10名女性，在18个月内接受了两次检查。这些受试者易患严重的咬合磨损，平均年龄为32岁，年龄范围在16至56岁之间。在研究模型上，逐颗牙齿地使用两个有序量表对咬合磨损进行评估，一个用于评估严重程度，另一个用于评估咬合磨损的进展情况。通过观察者间百分比一致性来评估量表的可靠性。与后牙区域相比，样本在前牙和尖牙区域表现出更高的咬合磨损分数。研究发现，在18个月的随访期内总体进展缓慢。观察者间在磨损严重程度评估方面的一致性为88%，在磨损进展评估方面为91%。在所描述系统的局限性范围内，这些量表可用于确定个体牙列中咬合磨损的严重程度及其恶化速率。从临床角度来看，未来治疗的必要性可能基于对磨损进展情况的此类评估。
