This review of the diagnostic accuracy of ultrasound in differentiating periapical lesions of endodontic origin in comparison with histopathology included 12 studies. While the findings suggest good levels of sensitifity and specificity for diagnosing periapical cysts and granulomasthere are concerns regarding the quality of the evidence.

This Cochrane review of the diagnostic accuracy of different electrical conductance devices for the detection and diagnosis of non-cavitated coronal dental caries included 7 studies. The quality of the studies mean we are very uncertain of how electrical conductance devices are in detecting and diagnosing early tooth decay.

This Cochrane review of the diagnostic accuracy of different dental imaging methods for early enamel lesions included 104 datasets from 77 studies. Low-certainty evidence suggests that imaging for the detection or diagnosis of early tooth decay may result in a relatively high proportion of false-negative results.

This review of difference concentrations of hydrogen peroxide for in-office dental bleaching on colour change and bleaching sensitivity included 25 RCTs. The findings indicate that low and medium hydrogen peroxide concentrations had lower risk and intensity of bleaching sensitivity and no difference in colour change efficacy compared with high concentrations.
