Dental caries detector is a kind of diagnostic tool specifically designed for dental professionals to detect and monitor the early occurrence and development of dental caries. They are widely used in the clinic because of their advantages of rapid detection, flexible applications, ease of carrying, intuitive detection results and lack of pain for the patient. However, due to the different types and principles of the instruments produced by various instrument manufacturers, the clinical application range, sensitivity and specificity of test results also show significant differences. In terms of the current clinical application effects, although the DIAGNOdent caries detector has the widest range of clinical use, the accuracy of its detection results needs to be improved because it is affected by factors such as pigments and dental materials. The Canary System caries detector can effectively avoid the interference of the above factors, but its classification of the degree of caries is not clear. The DIAGNOcam caries detector can effectively detect early caries, but it has low reliability for occlusal caries detection. The existing dental caries detectors on the market can be used only as clinical auxiliary tools, and the accuracy of the detection results and comprehensiveness of the detection range need further improvement. With the application of the new multispectral near-infrared scanning fiber endoscope (NIR-SFE) and high-frequency ultrasound imaging (HFUS) in the detection of dental caries, a more efficient and accurate diagnosis of dental caries is possible in the future. To this end, we still need to continue exploring new technology to help clinicians complete the early diagnosis and treatment of dental caries to improve the quality of life of their patients.

龋齿检测仪是一种专门为牙科设计的诊断工具,主要用于检测并监测龋病早期发生、发展过程。因其具有检测快速、无痛、灵活易携、检测结果直观等优点,被广泛应用于临床。然而,由于仪器制造商生产出的仪器种类、原理不同,它们的临床应用范围、检测结果的敏感性、特异性也显示出明显差异。就目前的临床应用效果来看,DIAGNOdent龋齿检测仪在临床使用范围广,但因其受色素、牙科材料等因素的影响,其检测结果的准确性有待提高;The Canary System龋齿检测仪则有效规避了上述因素的干扰,但其对龋损程度的分级并不明确;DIAGNOcam龋齿检测仪可以有效地检测出早期邻面龋,但 面龋的检测结果可靠性低。由此看出,目前市面上现有的龋齿检测仪仅可作为一种临床辅助工具使用,其检测结果的准确性、检测范围的全面性仍需进一步提高。随着新型多光谱近红外扫描纤维内窥镜、高频超声成像在龋齿检测上的研究应用,可提高龋齿诊断的高效性与准确性。
