Mineral trioxide aggregate (MTA), has been successfully used in difficult endodontic situations such as immature pulp less teeth and vital pulp therapy. Portland cement (PC), which forms the bulk of MTA, has been reported to exhibit similar properties. The physical properties and biocompatibility of PC has been researched in vitro and on animals, with a few studies on humans as well. This artic...

Endodontic filling materials may be considered true implants as they touch and are based in vital tissues of the body, and protrude to meet the external surface directly or, more appropriately, indirectly via another surface restoration (Fig. 1). It follows that the materials must possess several different properties relative to their functions and location, ranging from biocompatibility to mec...

Effective irrigant delivery and agitation are prerequisites to promote root canal disinfection and debris removal and improve successful endodontic treatment. This paper presents an overview of the currently available technologies to improve the cleaning of the endodontic space and their debridement efficacy. A PubMed electronic search was conducted with appropriate key words to identify the re...

Introduction. This experimental study is to compare radiographs based on the penetration depth of the irrigant following three final irrigation techniques. Material and Method. A sample of sixty teeth with single roots were prepared with stainless steel K files followed by mechanized Ni-Ti files iRace® under irrigation with 2.5% sodium hypochlorite. Radiopaque solution was utilized to measure t...

Root canal sealers with antimicrobial activity are highly beneficial; therefore, their antimicrobial properties could be improved by incorporation of antimicrobial agents. In the present study, the release of the quaternary ammonium compounds from endodontic sealers admixed with either benzalkonium chloride (BC) or cetylpyridinium chloride (CPC) at loadings of 2% wt was monitored. The effect of...

BACKGROUND The quality of the coronal seal of root canal filling material is important for periapical health. Absorption of water or saliva by the temporary restorative materials leads to dimensional changes, loss of retention, staining and breaking in margin contours. Hence this study was carried out to evaluate and compare the sealing properties, water absorption and solubility of IRM (interm...

root perforations are an undesired complication of endodontic treatment which result in loss of integrity of the root, and adversely affect the prognosis of the treatment. recently, iranian mineral trioxide aggregate (root mta) has been introduced as an ideal material for perforation repair. in this article a successful repair of strip root perforation of mandibular molar using root mta is pres...

AIM To compare posts of different flexibility using static load testing. Hypotheses tested were (1) the flexural modulus of endodontic posts does not show a linear relationship with failure load and (2) the flexural modulus of endodontic posts does not show an association with failure mode. METHODOLOGY Thirty 2 mm diameter rods of a glass fibre material Aesthetiplus (A), a carbon fibre Compos...
