BACKGROUND One of the essential properties of the root canal sealers is the adhesion to root canal dentin and their higher bond strength decreases the microleakage. The aim of the present study was to compare the effect of Different Intracanal medicaments on the push out bond strength of AH26 and MTA Fillapex sealers. MATERIAL AND METHODS A total of 104 one-rooted extracted human teeth were d...

persistent microorganisms in the root canal are known to cause endodontic treatments failure. overextended gutta-percha can also act as a periradicular tissue irritant, leading to large periapical lesions. retrieval of overextended gutta-percha with a nonsurgical approach can prove to be a challenge. this case describes the nonsurgical management of a large periapical lesion associated with ove...

The key goals of endodontic therapy include the removal of pulp remnants, necrotic tissue, micro-organisms, and microbial byproducts from the root canal system. Although this may be achieved through endodontic preparation, complete removal is difficult because of the intricate root canal anatomy [1]. Isthmi, apical deltas, intercanal communications, and loops are commonly observed in root canal...

  Objective: In necrotic immature teeth, intra canal medicaments such as triple antibiotic paste (TAP) and calcium hydroxide (CH) are used for root canal disinfection and regeneration treatment. However, the effect of these medicaments on dental pulp fibroblasts has yet to be known. This study aimed to assess the cytotoxicity of CH and TAP against cultured human dental pulp fibroblasts (HDPFs) ...

introduction: the aim of this in vitro study was to compare the effectiveness of three intracanal medicaments in disinfecting the root canal and dentin of experimentally infected human teeth with enterococcus faecalis (ef). materials and methods: one hundred extracted human single-rooted teeth were used. after root canal preparation, teeth were mounted in epoxy resin. following sterilization, t...

introduction: an ideal intracanal medicament should be able to eliminate any remaining intracanal microorganism. the aim of this study was to compare the antimicrobial effects of bioglass 45s5 with calcium hydroxide on enterococcus ( e ) faecalis in-vitro . materials & methods: direct exposure test (det) was used to evaluate the antimicrobial effect of bioglass 45s5, calcium hydroxide and norma...

The role of microorganisms in the development and maintenance of pulpal and periapical inflammation have been well documented. The success of root canal treatment largely depends on the elimination of microbial contamination from the root canal system. Although mechanical instrumentation of root canals can reduce bacterial population, effective elimination of bacteria cannot be achieved without...

BACKGROUND Candida has been associated with cases of secondary and persistent root canal infections. The purpose of this study was to evaluate and compare the effectiveness of commonly used intracanal medicament against Candida biofilms found in root canals of human primary teeth with necrotic pulp. MATERIALS AND METHODS Pulp canals of 45 single-rooted primary maxillary anterior teeth with pu...

Microorganisms play a major role in initiation and perpetuation of pulpal and periapical diseases. Therefore, elimination of the microorganisms present in the root canal system is the fundamental objective of endodontic treatment. The use of mechanical debridement, chemical irrigation or other antimicrobial protocols and intra-canal medicaments are critical to attain this goal. The aim of this ...
