Three Visual–Diagnostic Methods for the Detection of Enamel Cracks: An In Vitro Study 
by Tim Hausdörfer, Lisa Harms, Philipp Kanzowand Michael Hülsmann

Excerpts from the paper:

Studies show that a cracked tooth is the third most common reason for tooth loss in developed countries. If detected early and accurately, patients can retain their teeth for a longer time. Unfortunately, most cracks remain undetected in the early phase due to nonspecific symptoms and a lack of adequate diagnostic tools. Within this study, only methods already routinely used in dental practice were evaluated.

To the best of our knowledge, this study assessed the validity of three examination methods readily available in dental practice for crack diagnosis under standardized conditions with two different examiners for the first time. With the limitations of an in vitro study, it can be concluded that FOTI and NIR are suitable for crack detection. Especially in the accessible tooth surfaces (vestibular and oral), we found good values for sensitivity and specificity. Unfortunately, no single method was able to estimate the exact crack depth.

Diagnosis of cracked tooth: Clinical status and research progress
by Mingyue Yu, Jianing Li, Shuang Liu, Zunxuan Xie, Jinyao Liu, and Yuyan Liu

Excerpts from the paper:

Cracked tooth is a common dental hard tissue disease. The involvement of cracks directly affects the selection of treatment and restoration of the affected teeth. It is helpful to choose more appropriate treatment options and evaluate the prognosis of the affected tooth accurately to determine the actual involvement of the crack. However, it is often difficult to accurately and quantitatively assess the scope of cracks at present. So it is necessary to find a real method of early quantitative and non-destructive crack detection. This article reviews the current clinical detection methods and research progress of cracked teeth in order to provide a reference for finding a clinical detection method for cracked teeth.
