Key Points

This research aims to compare the diagnostic accuracy of Optical Coherence Tomography and the North Carolina Index in classifying dentin sclerosis in noncarious cervical lesions.
Compared diagnostic methods: Optical Coherence Tomography (OCT) and North Carolina Index (NCI)
Evaluated classification of dentin type in noncarious cervical lesions (NCCLs)
Analyzed accuracy in predicting dentin substrate for restorative choices
OCT demonstrated superior accuracy over NCI in classifying dentin types.
Findings suggest OCT can better predict the nature of dentin in NCCLs, influencing treatment decisions.

Abstract

Although NCI is widely used for clinical evaluation, OCT has proven to be a more accurate technique for classifying dentin type in NCCLs, providing possible predictability of the dentin substrate and assisting in the choice of restorative technique and material.
