statement of the problem: endodontic surgery if required is considered as an additive therapy after classic endodontic treatments. the most prevalent type of endodontic surgeries are apicoectomy and corrective surgeries. type of material applied in apicoectomies is of high importance. root end filling material should not only be biocompatible but also provide appropriate seal. considering these...

Mineral trioxide aggregate (MTA) has emerged as a reliable bioactive material with extended applications in endodontics that include the obturation of the root canal space. This article examines the literature supporting MTA as a canal filling material, suggests methods for its delivery and placement, and presents clinical cases that demonstrate its effectiveness in resolving apical periodontit...

Endodontic surgical procedures involve the use of a root-end filling material to provide an apical seal and to facilitate the repair and regeneration of periradicular tissues. Whereas earlier studies typically evaluated the cytotoxicity of these materials, contemporary research has focused on their capacity to support a favourable cellular response. In vitro tissue culture techniques have demon...

The toxicity of endodontic materials is reviewed. The patient may be exposed by constituents leaching from the unset and set sealer and by accidental overfilling of the root canal. For most patients the exposure is believed to be below the threshold for a toxic effect. Most sealers exhibited a cytotoxic response, especially unset and the responses diminished with time after setting. Unset and n...

BACKGROUND Mineral trioxide aggregate, or MTA, is a new material developed for endodontics that appears to be a significant improvement over other materials for procedures in bone. It is the first restorative material that consistently allows for the overgrowth of cementum, and it may facilitate the regeneration of the periodontal ligament. CASE DESCRIPTION The authors present five cases in w...

Introduction: Internal root resorption is a progressive loss of dentin in teeth with inflamed and possibly partially necrotic pulp tissue. If diagnosed at early stages, the process is halted by endodontic treatment. While endodontic treatment is the preferred treatment modality for internal root resorption, current standard endodontic techniques pose a challenge for cleaning, disinfection and o...

AIM To present a newly developed cone beam computerized tomography system (3DX Micro-CT) and its application in endodontic surgery. SUMMARY Cone beam CT has attracted considerable attention as a new diagnostic imaging technique in dentistry. The assessment of fractured endodontic instruments and the planning of endodontic surgery present challenges that conventional radiography cannot meet su...

Successful Endodontic therapy is based on cumulative results of complete debridement and disinfection of root canal system, followed by a three dimensional obturation [1]. However, certain anatomic complexities such as very fine canals such as those commonly encountered in geriatric cases and extremely curved canals can pose a real challenge to the treating dentist [2]. Inability to completely ...

The purpose of this article is to describe a simple and versatile aid for the endodontic treatment of extracted teeth and its possible applications. The Med*-box is a new endodontic multipurpose device made of transparent acrylic that permits all elements of root canal treatment to be performed and evaluated either visually or radiologically. The Med*-box represents a valuable addition to the s...
