A review of the questions and needs in endodontic diagnosis.

The current diversity of opinions in endodontic diagnosis has been a source of interest and academic debate by clinicians and researchers. Currently, no single pulp testing technique can reliably diagnose all pulpal conditions neither it has been proven to be superior in all aspects. Despite improvements of various aspects of this process, there are no historically dramatic changes, or consensus for pulpal status in health or disease in addition to a lack of relative systematic reviews. In this review, the past, present and future most debated and critically questioned issues of endodontic diagnosis are discussed. The aim of this review is to provide insights in future diagnostic modalities and areas for further study in endodontic practice pertinent to diagnosis.
