If tooth lesions in the early stages, such as white spots, hidden dental caries, and tooth decay, etc., are not detected and treated promptly, they will lead to a risk of tooth loss. There are several common methods to detect tooth lesions such as clinical method, X-rays, and particularly near-infrared method, which is being developed significantly during the past decades. This method is substantially efficient for detecting early lesions by observing infrared images of tooth structures. In this study, near-infrared (NIR) light at 850 nm was used for detecting dental lesions. Enamel is nearly translucent in NIR light, so the lesions located under the enamel layer can be observed due to the interaction between NIR light and demineralized lesions. In addition, the NIR method is not only a safe method but also able to detect dental lesions at the early stage and tooth cracks which X-rays are limited to detect. In dentistry, an accurate diagnosis requires a combination of methods. Nowadays, X-rays are not only the common method but also the gold standard in dentistry, so this study incorporated clinical evaluation and X-rays to make the criteria for dental lesion diagnosis. This article has aimed to analyze and evaluate the effectiveness of the NIR imaging systems in detecting dental lesions and compare the NIR method to the clinical method combined with X-rays by Cohen's Kappa coefficient using SPSS (Statistical Package for the Social Sciences).Keyphrases: dental lesions, effectiveness, near infrared, spss, x rays In: Tich Thien Truong, Trung Nghia Tran, Quoc Khai Le and Thanh Nha Nguyen (editors).
