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...

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 basis of endodontic treatment is elimination of microorganisms from the root canal. Cleaning and shaping is usually not enough to reduce the bacterial count in the root canals. Many resistent microorganisms stay back and continue to multiply increasing the chances of failure of the treatment. Hence intracanal medicaments are necessary and various intracanal medicaments have been tried. Calc...

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...

Literature review The primary function of calcium hydroxide as a routine intracanal medicament is to provide antimicrobial activity. However, the mechanisms of antimicrobial activity of calcium hydroxide are not well known. Physicochemical properties of this substance may limit its effectiveness in disinfecting the entire root canal system. In addition, calcium hydroxide is not effective agains...

BACKGROUND Optimal antibacterial efficacy of intracanal medicaments containing silver nanoparticles (Ag-NPs) has been well documented. However, concerns remain regarding the effect of Ag-NPs on tooth color. This study aimed to assess the effects of calcium hydroxide (CH) mixed with Ag-NPs as intracanal medicaments on tooth color. The effect of location of application of medicament on the degree...

Irrigation solutions and intracanal medicaments are used within the root canal to clean and aid in disinfecting the dentinal walls. Although these materials are intended to be contained within the root canal, they invariably contact the periapical tissues, either through inadvertent extrusion through the apex or leaching. This paper is a review on the methodology involved in biocompatibility te...

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...
