Application of Photoacoustic System for Caries Detection: Systematic Review

Abstract

This research was done in the form of a thorough assessment of the systematic review on the application of photoacoustic methods to detect dental caries. This paper also reviews the broader applications of photoacoustic techniques in dentistry, beyond their use in detecting specific dental diseases. The method employed in this review paper begins with the identification of relevant studies, followed by screening and eligibility assessment. Finally, the selected articles are ready for comprehensive review. Out of 2,940 papers initially considered, only seven were accepted for analysis. This selection was based on several criteria that have been set for reviewing the articles. It was evident that only three out of the seven articles focused on the issue of dental caries. The review recommends two things for future studies. First, it suggests using qualitative studies for detecting caries lesions because they provide detailed and in-depth insights for dentists to make informed treatment decisions. Second, it anticipates a high demand for new technology that is non-invasive, radiation-free, and handheld for detecting caries lesions, as such technology does not currently exist.
