Abstract

Objectives

This study aimed to validate the use of 3D images obtained with an intraoral scanner (IOS) for caries detection in a population-based cohort study.

Methods

A random sample of individuals from the Pelotas 1982 Birth Cohort was assessed at 40 years of age. Calibrated dentists clinically examined participants using merged ICDAS criteria for caries lesion detection at the tooth surface level: 0 – sound; A – initial lesion; B – moderate lesion; C – severe lesion. 3D images were acquired using an IOS (TRIOS 3 – 3Shape®). A calibrated evaluator assessed dental caries through 3D images using the same ICDAS criteria. Diagnostic properties of using IOS 3D images to detect caries were calculated, considering the clinical examination as the gold standard, with different cut-off points based on lesion stage at individual, tooth, and surface levels.

Results

A total of 99 individuals, 2664 teeth, and 11,519 surfaces were assessed. At the individual level, sensitivity values for initial, moderate, and severe lesions were 86.1 %, 77.8 %, and 80.6 %, respectively. Specificity was 40 % for initial, 55.6 % for moderate, and 93.7 % for severe lesions. At the tooth level, sensitivity was 38.6 % for initial, 56.8 % for moderate, and 72.5 % for severe lesions, with specificity values ranging from 91.5 % to 99.4 %. At the surface level, sensitivity values were 50.2 % for initial, 71.7 % for moderate, and 82.0 % for severe lesions. Specificity values at the surface level were all higher than 97 %. Areas under the ROC curve varied from 0.63 to 0.91, considering all levels and cut-off points. Diagnostic properties improved as the severity of lesions increased for all analysis levels.

Conclusions

The findings suggest that 3D images obtained through an intraoral scanner may be a valid tool for assessing dental caries in epidemiological settings, particularly for detecting moderate to severe lesions.

Clinical Significance

This study validates intraoral scanners as a tool for detecting moderate and severe caries lesions in epidemiological research, with the possibility of use for remote diagnosis, telehealth applications, and standardized data collection in large-scale oral health surveillance.

口腔内扫描仪作为龋病流行病学诊断工具的有效性验证。

目的：本研究旨在验证在一项基于人群的队列研究中使用口腔内扫描仪（IOS）获得的3D图像进行龋检测。方法：从1982年Pelotas出生队列中随机抽取40岁的个体进行评估。校准后的牙医使用合并的ICDAS标准对参与者进行临床检查，以检测牙齿表面的龋齿损伤：0 -声音；A -初始病变；B -中度病变；C -严重病变。使用IOS （TRIOS 3 - 3Shape®）获取3D图像。经过校准的评估人员使用相同的ICDAS标准通过3D图像评估龋齿。以临床检查为金标准，根据个体、牙齿和表面的病变阶段设置不同的截止点，计算IOS 3D图像检测龋的诊断特性。结果：共有99人，2664颗牙齿和11519个表面被评估。在个体水平上，初始、中度和重度病变的敏感性值分别为86.1%、77.8%和80.6%。原发性病变特异性为40%，中度病变特异性为55.6%，重度病变特异性为93.7%。在牙齿水平上，初始病变的敏感性为38.6%，中度病变为56.8%，重度病变为72.5%，特异性值为91.5%至99.4%。在表面水平上，初始敏感性为50.2%，中度敏感性为71.7%，重度敏感性为82.0%。表面特异性值均大于97%。考虑到所有水平和分界点，ROC曲线下面积从0.63到0.91不等。随着病变严重程度的增加，所有分析水平的诊断性能都有所提高。结论：研究结果表明，通过口腔内扫描仪获得的3D图像可能是一种有效的工具，用于评估流行病学背景下的龋齿，特别是用于检测中度至重度病变。临床意义：本研究验证了口腔内扫描仪作为流行病学研究中检测中重度龋齿病变的工具，在大规模口腔健康监测中具有远程诊断、远程医疗应用和标准化数据收集的可能性。

期刊介绍： The Journal of Dentistry has an open access mirror journal The Journal of Dentistry: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The Journal of Dentistry is the leading international dental journal within the field of Restorative Dentistry. Placing an emphasis on publishing novel and high-quality research papers, the Journal aims to influence the practice of dentistry at clinician, research, industry and policy-maker level on an international basis. Topics covered include the management of dental disease, periodontology, endodontology, operative dentistry, fixed and removable prosthodontics, dental biomaterials science, long-term clinical trials including epidemiology and oral health, technology transfer of new scientific instrumentation or procedures, as well as clinically relevant oral biology and translational research. The Journal of Dentistry will publish original scientific research papers including short communications. It is also interested in publishing review articles and leaders in themed areas which will be linked to new scientific research. Conference proceedings are also welcome and expressions of interest should be communicated to the Editor.
