Apoptosis plays an important role in many aspects of endodontics, yet there is a paucity of information in this regard in the endodontic literature. Apoptosis is a single deletion of scattered cells by fragmentation into membrane- bound particles that are phagocytosed by other cells. It is a key process in the embryological development of the tooth, periodontal ligament and supporting oral tissue in the progression of oral disease, bone resorption, immunological response and inflammation, and in wound healing and certain pharmacological effects. The understanding of the ability of clinical materials to induce or inhibit apoptosis and the investigation of apoptosis as it relates to the pathogenesis of pulpal and periradicular pathology may eventually lead to new treatment approaches for the endodontist. The purpose of this review is to familiarize the clinical endodontist with current knowledge on apoptosis as it relates to the pulp and periradicular tissues.

Aim.
To compare mineral trioxide aggregate (MTA) with calcium hydroxide when used as pulp-capping materials in human teeth.

Conclusions.
Although the results favour the use of MTA, more studies with larger samples and a longer follow up are suggested.
» The capability of two hand instrumentation techniques to remove the inner layer of dentine in oval canals
By JofER editor | Published 04/8/2009 | Endodontic Articles 16 | Unrated

Aim.
To evaluate the capability of two hand instrumentation techniques, namely balanced force and circumferential filing, to remove the inner layer of dentine in oval canals.

Conclusion.
In oval canals, both the balanced force and circumferential filing techniques left large portions of the canal wall uninstrumented.
