Introduction: Dental composites are the most commonly used as well as preferred among all the conventional restorative materials as far as esthetics is concerned. One of the major drawbacks of composite resin is their polymerisation shrinkage and stresses. Hence, the requirement of adequate knowledge of the material aspects and trained operatory skills in composite insertion techniques are very much essential. The Aim of this study was to compare bulk fill composite (SDR) with an incremental nanofilled composite (3M ESPE Z350XT) for adaptability at pulpal floor and subsequent interfacial gap formation between increments.

Introduction: Elimination of microorganisms from the root canal and preventing them from reinfecting is the main objective of endodontic treatment. The sealers exhibit antimicrobial activity that may contribute to the elimination of intracanal microorganisms and the success of endodontic treatment. Aim: To evaluate the antibacterial and antifungal activities of different root canal sealers against endodontic pathogens.
