OBJECTIVE To evaluate and compare the antimicrobial efficacy of 6% Morinda citrifolia, Azadirachta indica, and 3% sodium hypochlorite (NaOCl) as root canal irrigants. MATERIALS AND METHODS Thirty nonvital maxillary anteriors were randomly assigned to one of the three groups corresponding to the irrigant to be tested; 6% Morinda citrifolia juice (MCJ) (n = 10), A. indica (n = 10) and 3% NaOCl ...

Endodontic emergencies are associated with pain and swelling which requires immediate diagnosis and treatment. The main causative factors for these emergencies are pulp and peri-radicular pathosis, traumatic injuries, procedural complications; were sodium hypochlorite accidents can occur. The impetus behind a successful root canal treatment relies on a thorough debridement of tissue remnants, b...

AIM To determine the influence of volume, irrigant and method of flushing on the removal of artificially-placed dentine debris from the apical part of root canals during passive ultrasonic irrigation. METHODOLOGY Access cavities were prepared in 15 canine teeth and their root canals instrumented to size 20, 0.10 taper. Each root was split longitudinally, forming two halves. A groove was cut i...

Background: Efforts to improve the efficacy of smear layer removal by applying irrigant activation at the final irrigation or by elevating the temperature of the irrigant have been reported. However, the combination of such activation protocols with 60°C 3% sodium hypochlorite (NaOCl) has seldom been mentioned. The aim of this study was to compare the efficacy in smear layer removal of four dif...

Abstract Background We established an in vivo intraradicular biofilm model of apical periodontitis pigs which we compared the efficacy different irrigant activation techniques for removal. Methods Twenty roots from deciduous mandibular second premolar 5 male were used. After pulpectomy, canals left open 2 weeks and then sealed 4 to enable development intracanal biofilm. The biofilms was evaluat...

OBJECTIVES The present study was conducted to compare the cleaning efficacy (debris and smear layer removal) of hand and two NiTi rotary instrumentation systems (K3 and ProTaper). MATERIALS AND METHODS Sixty single rooted human maxillary anterior teeth decoronated at the cementoenamel junction were used. All the specimens were divided into four groups of 15 teeth each, group I--ProTaper rotar...
