Objectives

This study aims to systematically review the different methods used for wear measurement of dental tissues and materials in clinical studies, their relevance and reliability in terms of accuracy and precision, and the performance of the different steps of the workflow taken independently.

Methods

An exhaustive search of clinical studies related to wear of dental tissues and materials reporting a quantitative measurement method was conducted. MedLine, Embase, Scopus, Cochrane Library and Web of Science databases were used. Prospective studies, pilot studies and case series (>10 patients), as long as they contained a description of wear measurement methodology. Only studies published after 1995 were considered.

Results

After duplicates’ removal, 495 studies were identified, and 41 remained for quantitative analysis. Thirty-four described wear-measurement protocols, using digital profilometry and superimposition, whereas 7 used alternative protocols. A specific form was designed to analyze the risk of bias. The methods were described in terms of material analyzed; study design; device used for surface acquisition; matching software details and settings; type of analysis (vertical height-loss measurement vs volume loss measurement); type of area investigated (entire occlusal area or selective areas); and results.

Sinificance

There is a need of standardization of clinical wear measurement. Current methods exhibit accuracy, which is not sufficient to monitor wear of restorative materials and tooth tissues. Their performance could be improved, notably limiting the use of replicas, using standardized calibration procedures and positive controls, optimizing the settings of scanners and matching softwares, and taking into account unusable data.

临床研究中牙齿组织和材料的磨损测量：系统评价

目标

本研究旨在系统地回顾临床研究中用于牙齿组织和材料磨损测量的不同方法，它们在准确性和精度方面的相关性和可靠性，以及独立采取的工作流程不同步骤的性能。

方法

对报告定量测量方法的牙科组织和材料磨损相关的临床研究进行了详尽的搜索。使用了 MedLine、Embase、Scopus、Cochrane Library 和 Web of Science 数据库。前瞻性研究、试点研究和病例系列（>10 名患者），只要它们包含磨损测量方法的描述。仅考虑 1995 年之后发表的研究。

结果

删除重复项后，确定了 495 项研究，其中 41 项仍用于定量分析。34 个描述了磨损测量协议，使用数字轮廓测量和叠加，而 7 个使用替代协议。设计了一个特定的表格来分析偏倚的风险。这些方法是根据分析的材料进行描述的；学习规划; 用于表面采集的设备；匹配软件详细信息和设置；分析类型（垂直高度损失测量与体积损失测量）；研究区域的类型（整个咬合区域或选择性区域）；和结果。

意义

临床磨损测量需要标准化。目前的方法表现出准确性，这不足以监测修复材料和牙齿组织的磨损。它们的性能可以提高，特别是限制复制品的使用，使用标准化的校准程序和阳性对照，优化扫描仪和匹配软件的设置，并考虑到不可用的数据。
