Identification of Middle Mesial Canal in Mandibular Molars Using Five Different Techniques: An Study.

Aim: The purpose of the study was to find out the incidence of the middle mesial canal in mandibular molars by using five different techniques.

Materials And Methods: A total of 150 extracted human mandibular first molars were selected, and cone beam computed tomography (CBCT) images were taken. Then, conventional access cavities were made, followed by troughing under dental loupes (3X), and were also examined under a dental operating microscope (DOM) (6X).

Evaluation and Comparative Analysis of Coronal Tooth Discoloration Induced by Four Endodontic Biomaterials Utilized in Regenerative Endodontic Procedures: An Ex-vivo Study.

Aim: This study aims to compare and evaluate the changes in color caused by four different biomaterials utilized as intracanal coronal barriers in the regenerative endodontic procedure at varying intervals of time.

Methods: A total of 100 extracted mandibular single-rooted premolars were taken. Samples were standardized, and access cavity preparation was done.
