Summary

Dental caries (dental cavity) is very common and can impact oral health and oral health-related quality of life. Dental caries is when the tooth surfaces break down, and if left untreated, can cause tooth pain. In routine clinical practice, dental professionals typically assess caries lesions by looking at patients' teeth, touching the areas of interest with a dental probe, and running a probe over the teeth to check the buildup of bacteria. Dentists often use x-rays to help find cavities, and they can also take pictures of the teeth to show what the problem looks like. New tools called intraoral scanners are becoming more useful for finding cavities. These scanners do not use radiation and do not hurt. Some computer programs that use artificial intelligence (AI) can also help dentists find cavities. AI can study the spots on patients' teeth and help make better, faster decisions. The purpose of this study is to collect data that will be used to develop and test an AI software that can help dentists in the detection of caries.

Detailed description

This is a single-arm, cross-sectional, open single-site clinical investigation using TRIOS 5 and TRIOS 6 intraoral scanners. After enrolment, the participant will first undergo an intraoral scan. Next, the participant's teeth will be cleaned to remove plaque and debris, ensuring optimal conditions for the caries examination. Dental bitewing radiographs will be taken to assess any potential caries not visible on the scan. A second intraoral scan will be performed on the cleaned teeth. The examiner will then conduct an examination using standardized diagnostic criteria to assess the presence of caries, and will take intraoral photos of the caries lesions. The AI-based software will provide a digital assessment of caries for comparison with the clinical evaluation. This comparison will be conducted separately from the clinical data collection. The comparison of the AI output to the clinical data will be performed internally at 3Shape headquarters of Holmens Kanal 7, 1060, Copenhagen, Denmark. This test has no impact on the patients in this study.
