摘要：

Detection of cracks in teeth and the evaluation of a dental restoration in a non-invasive way is of paramount importance in clinical practice. Common dental X-ray diagnosis is precise but causes a lot of concerns due to its ionizing radiation nature, not-so-comfortable patient experiences, as well as used-in-caution for women in pregnancy, etc. The advanced works on dental inspection using laser lock-in thermography has proven to be effective with good sensitivity and resolution. The aim of this study is to compare the detection efficiency using different laser power, and laser modulation frequency.
