Since its advent, the dental CAD/CAM system has evolved to completely revolutionise the way of practicing restorative dentistry. Dental CAD/CAM system is approaching 20 years of clinical experience and has a proven track record on all relevant aspects of clinical performance including fit, longevity, survival rates, sensitivity, strength and wear of the restorations. In the present scenario, it plays an important role in treatment planning, impression making as well as design and manufacturing of highly esthetic restorations.

Since decades, irrigants have been delivered into root canal space using syringes and metal needles of different sizes and tip design. Clinical researches have shown that classic approach of irrigant delivery results in ineffective irrigation in areas like anastomoses between canals, fins and most apical part of the main root canal. Therefore, technological advances have brought new agitation devices that rely on various mechanisms of irrigant transfer, soft tissue debridement and removal of smear layer through manual and machine assisted agitation systems. Overall review has been concluded...

The revitalization approach for managing immature permanent teeth with infected pulp and/or apical periodontitis allows the ingrowth of vital tissue consisting of tissues resembling cementum, PDL, bone. These tissues are not pulp tissues. They do not function like pulp tissue. Therefore revitalization is better termed as wound repair. Pulp tissue may survive infection, recover, and remain healthy. The clinical case reports have shown narrowing of canal and root lengthening however. Although revitalization procedure is more favorable than the traditional apexification procedures in terms of...
