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...
INTRODUCTION Irrigants play an essential role in the successful debridement and disinfection of pulp space. Various combination of irrigants used during root canal treatment enhance their efficacy, but some form precipitates which affects the diffusion of intracanal medicaments and the seal of the obturated root canal. AIM To evaluate the combination of various irrigants whether it forms the ...
Background and Aim: During root canal therapy, it is necessary to remove as many bacteria as possible from the root canal. The use of medicaments is recommended to reduce the microbial population prior to root filling. Calcium hydroxide pastes have been used because of their antibacterial effects and the ability of tissue dissolving. The aim of this study was to evaluate the effect of calcium h...
The antibacterial activity of β-lactam derived polycyclic fused pyrrolidine/pyrrolizidine derivatives synthesized by 1, 3-dipolar cycloaddition reaction was evaluated against microbes involved in dental infection. Fifteen compounds were screened; among them compound 3 showed efficient antibacterial activity in an ex vivo dentinal tubule model and in vivo mice infectious model. In silico docking...
apical extrusion of debris and irrigants during cleaning and shaping of the root canal is one of the main causes of periapical inflammation and postoperative flare-ups. the purpose of this study was to quantitatively measure the amount of debris and irrigants extruded apically in single rooted canals using two reciprocating and one rotary single file nickel-titanium instrumentation systems.sixt...
introduction: disinfection and subsequent obturation of the root canal space require adequate mechanical enlargement of the canals. the purpose of this in vitro study was to compare the shaping ability of mtwo, race and medin rotary instruments during the preparation of curved root canals. materials and methods: sixty mesiobuccal root canals of mandibular molars with severe curvatures between 2...
Microbial biofilm is defined as a sessile multicellular microbial community characterized by cells that are firmly attached to a surface and enmeshed in a self-produced matrix of extracellular polymeric substances. Biofilms play a very important role in pulp and periradicular pathosis. The aim of this article was to review the role of endodontic biofilms and the effects of root canal irrigants,...
introduction: the aim of the present in vitro study was to evaluate the disinfection ability of 980-nm diode laser in comparison with sodium hypochlorite (naocl) as a common root canal irrigant in canals infected with enterococcus faecalis ( e. faecalis ). methods and materials: the root canals of 18 extracted single-rooted premolars were prepared by rotary system. after decoronation, the roots...
