Air abrasion dentistry has evolved over a period of time from a new concept of an alternative means of cavity preparation to an essential means of providing a truly conservative preparation for preservation of a maximal sound tooth structure. The development of bonded restorations in combination with air abrasion dentistry provides a truly minimal intervention dentistry. This article reviews the development of air abrasion, its clinical uses, and the essential accessories required for its use.

This articles describes a technique for placement of a matrix barrier prior to use of mineral trioxide aggregate (MTA) as an artificial root-end barrier. The technique also demonstrates the use of a delivery system utilizing large-bore needles for the predictable and precise placement of the barrier materials at the apex of the tooth.

This report describes a step-by-step sequence for preparation for a posterior partial veneered restoration for a space closure using a Maryland bridge—design veneered with a heat-cured composite resin. The modality provides sound posterior occlusal function, combined with a psychological satisfaction to the patient of regaining a missing tooth. The preparation takes into account the design for resin-bonded prostheses. This article presents the preparation and build-up method for a metal reinforced posterior partial veneered restoration through a conservative palatal approach for a highly aesthetic result.

The use of gutta-percha as a standard obturation material over more than 100 years has made little changes in the obturation technique. With the advent of bonding and composite resins as a routine restorative material, the concept of bonded obturation has come into picture. The Resilon-Epiphany system has brought about a paradigm shift in the conventional obturation technique. This article explores the possibilities of the material as a replacement for gutta-percha. It also discusses the currently available forms of the material and a clinical case depicting its use.
