Microorganisms may persist in the root canal system after therapy (RCT). The purpose of this study was to explore metronidazole (MTR)- and chlorhexidine (CHX)-loaded hydrogels as potential application intracanal medicaments for disinfection. Ultraviolet cross-linked (gGels) were synthesized by GelMA solution photoinitiator, which loaded with MTR (MTR@gGels) CHX (CHX@gGels). gGels, MTR@gGels CHX...

OBJECTIVE Up to 90% of the flora of an infected root canal consists of obligate anaerobic bacteria. However, most studies have centred on microaerophiles. This quantitative assay investigated the antibacterial effects against Fusobacterium nucleatum and Parvimonas micra of gutta-percha (GP) points containing either calcium hydroxide (Ca(OH)(2)) or chlorhexidine (CHX) compared to those of conven...

BACKGROUND Several medicaments have been used to devitalize remaining pulp or maintain pulp vitality and promote healing. Based on pulpal biocompatibility and good sealing ability, a growing interest in more biocompatible materials promotes mineral trioxide aggregate (MTA) as an alternative to traditional medicaments. Uniquely, MTA can preserve pulpal health predictably and promote healing with...

BACKGROUND: General dental practitioners provide the majority of endodontic treatment in Jordan. The aim of this study was to gather information on the methods, materials and attitudes employed in root canal treatment by dentists in North Jordan, in order to evaluate and improve the quality of current practice. METHODS: A questionnaire was posted to all registered general dental practitioners w...

Complete debridement and thorough disinfection of infected root canals are considered mandatory for the success of root canal treatment. However, canal preparation and irrigation are not always effective in eliminating total microflora from the root canal system. Traditionally, calcium hydroxide has proven to be an excellent intracanal medicament for infected root canals. However, it is known t...

BACKGROUND AND AIM Comparison of different irrigation and agitation methods for the removal of two types of calcium hydroxide medicaments from the root canal walls. METHODS Fifty extracted single rooted teeth were selected for this study. After decoronation, the root canals of these teeth were prepared to the size F3 (30 no.) using rotary ProTaper file system. These samples were randomly divi...

introduction: leakage of the root canal system is an importent consideration when placing an intracanal medicament. the aim of this in vitro study was to compare the effect of calcium hydroxide and 1% chlorhexidine gel as intracanal medicaments on tooth apical seal. materials and methods: seventy extracted, single-rooted maxillary anterior teeth were divided into the three experimental groups (...

Restorative dentistry involves use of various intracoronal and intracanal medicaments. Commonly used endodontic medicaments include paraformaldehyde, sodium hypochlorite and hydrogen peroxide. These agents are caustic and in higher and in inappropriate concentrations can cause immediate damage to the surrounding hard and/or soft tissues. Proper knowledge of such agents and careful use of such i...
