Laser irradiation during root canal treatment is efficient but in order to prevent irreversible thermal damage to dentine, cementum and other periapical structures continuous water cooling is required. The aim of this study was to ultrastructurally analyze the surface of intracanal dentine and cementum at the root apex after Er:YAG laser irradiation with and without sterile saline solution irri...

The success of root canal therapy is dependent not only on removal of infected pulp (pulpectomy) followed by root canal enlargement, but also on the pharmacological effects of intracanal medications. Various intracanal medications are used. Formaldehyde preparations such as formocresol were common in the past, but these are no longer used in Europe or the US due to the biological toxicity of fo...

OBJECTIVE The purpose of this study was to evaluate the action of sodium hypochlorite (NaOCl) associated with an intracanal medication against Candida albicans and Enterococcus faecalis inoculated in root canals. MATERIAL AND METHODS Thirty-six human single-rooted teeth with single root canals were used. The canals were contaminated with C. albicans and E. faecalis for 21 days and were then i...

BACKGROUND The aim of the present study was to evaluate the time-dependent effectiveness of the intracanal medicaments used in pulp revascularization on the dislocation resistance of mineral trioxide aggregate (MTA). METHODS One hundred ninety-two extracted human maxillary incisor teeth were sectioned apically 12 mm below and coronally 2 mm above the cemento-enamel junction. Roots were enlarg...

introduction: to assess the antibacterial effects of an iranian endemic essential oil, satureja khuzistanica jamzad (skj) when used as an intracanal antiseptic and interappointment medicament. materials and methods: antimicrobial activity and minimum inhibition concentrations (mics) of skj essential oil with and without calcium hydroxide (ch) against eleven aerobic, microaerophilic and anaerobi...

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...

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...

The antimicrobial and cytotoxic effects of Kri 1 paste, an iodoform-based primary tooth filling material, were compared with zinc oxide-eugenol (ZOE), using in vitro techniques. Antimicrobial evaluation involved measuring inhibition zones of Streptococcus faecalis on brain heart agar. Cytotoxicity evaluation involved direct cell-medicament contact experiments of 4-hr and 24-hr duration using fr...
