scope (DOM) was introduced to endodontics, offering significantly improved magnification and illumination. Bellizzi and Loushine advocated the benefits of optical magnification for posterior surgery.1 Carr stated that surgical and nonsurgical applications for the DOM have revolutionized the practice of endodontics.2 The advantage of the combined use of the DOM and visual guidance has been repor...

introduction ingestion of foreign bodies has been previously reported in some patients with schizophrenia. this behavior may be a manifestation of delusional beliefs or a response to command hallucinations and can lead to severe complications. case presentation this paper reports a patient with schizophrenia who, as a manifestation of his illness, ingested a metallic skewer to kill ademon insid...

Background: Perforation can occur while performing root canal treatment. Biodentine has been made utilizing MTA (mineral trioxide aggregate) as a base, and claims to improve its properties in aspects such physical property, durability, handling, well many other applications restorative dentistry. The chemical components of SDF (silver diamine fluoride) have suggested...

In the clinical practice, it is much more efficient to use NiTi rotary files compared to hand instrumentation. However, misuse of NiTi rotary files can result in procedural errors such as transportation, ledge, perforation, and file separation. Generally, following suggestions could be considered to avoid these errors. 1. Enlarge the coronal half of the root canal before preparing the apical pa...

statement of problem: nowadays mineral trioxide aggregate (mta) is widely used for root end fillings, pulp capping, perforation repair and other endodontic treatments. investigations have shown similar physical and chemical properties for portland cement and root mta with those described for mta. purpose: the aim of this in vitro study was to evaluate the tissue reaction to implanted mta, portl...

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...

AIM To evaluate the technical quality of root fillings performed in the undergraduate clinic of the Dental College, King Saud University, Saudi Arabia and to compare the technical quality of root canal treatment between the 4th- and 5th-year students. METHODOLOGY A random sample of 710 records of patients who had received dental treatment by undergraduate students at the College of Dentistry ...

Objective. The purpose of this study was to investigate the clinical and radiographic success of teeth restored with posts. Material and method. Periapical radiographs of 101 teeth with posts taken from 75 patients were examined. Posts were evaluated in terms of their position, remaining amount of gutta-percha, lengths and diameters, quality of root filling and periapical health. Furthermore, c...

Mineral trioxide aggregate (MTA) was developed in early 1990s and has been successfully used for root perforation repair, root end filling, and one-visit apexification. MTA is composed mainly of tricalcium silicate and dicalcium silicate. When MTA is hydrated, calcium silicate hydrate (CSH) and calcium hydroxide is formed. Formed calcium hydroxide interacts with the phosphate ion in body fluid ...
