The aim of this study was to evaluate, histopathologically, the effectiveness of mechanical preparation of root canals using different irrigating solutions in dog teeth filled with LPS after pulpectomy. A total of 120 root canals of 6 mongrel dogs were filled with a solution of LPS after pulpectomy. The irrigating solutions used were saline, 1, 2.5, and 5% sodium hypochlorite, and 2% chlorhexid...

Aim: To evaluate the effectiveness of four different irrigation regimes on removal of smear layer and smear plugs at the tubular apertures in the middle and apical thirds of the root canals by using Scanning Electron Microscopy(SEM). Settings and Design: In vitro material science study. Materials and methods: Twenty human mandibular first premolars were used for this study. The teeth were divid...

The in vitro reduction of the bacterial population in the root canal by the mechanical action of instrumentation and irrigation was evaluated. Root canals inoculated with a Enterococcus faecalis suspension were instrumented using hand Nitiflex files, Greater Taper (GT) files, and Profile 0.06 taper Series 29 rotary instruments. Irrigation was performed using sterile saline solution. Root canals...

AIMS A study was done to evaluate the antimicrobial efficacy of sodium hypochlorite (NaOCl) and photoactivated disinfection (PAD) on Enterococcus faecalis. SETTINGS AND DESIGN Random sampling, in-vitro study. SUBJECTS AND METHODS Access opening and biomechanical preparation were performed on fifty freshly extracted mandibular second premolars. The specimens were sterilized; 15 μm of E. faec...

his study aimed at evaluating the influence of EDTA, Nd:YAG laser and the combination of both for filling of artificial lateral root canals. Forty-five human mandibular premolars were employed, on which three artificial lateral root canals were prepared by means of a reamer with a similar diameter to a K file #15. The teeth were instrumented through the stepback technique employing Gates Glidde...

The operating quality of reclamation drainage and irrigation systems depends on the condition their main elements. elements are canals with various profiles, ranging from rectangular to parabolic. most widespread in land a trapezoidal profile. At same time, it is possible note that natural production characteristics quite diverse, this issue especially relevant for geometric parameters canals. ...

according to the current challenges toward low water use efficiency in agriculture, paying attention to the role of public participation in order to improve irrigation efficiency and effectiveness with useful methods and tools is essential. hence, approaches such as participatory irrigation management has been proposed and applied. after the primary investigation in this study, experiences of i...

Aim: To compare the efficiency of sonic irrigation, passive ultrasonic and conventional syringe irrigation (CI) in removing pure injectable calcium hydroxide (CH) from root canals mandibular second premolars by measuring probable microleakage residual CH particles canal obturation using computerized liquid filtration (CLF). Materials Methods: Eighty instrumented were categorized into three expe...

Burkina Faso is an agricultural and landlocked country whose agriculture dependent on climatic hazards. Irrigated therefore appears as alternative to secure, intensify sustainably increase production. However, irrigation systems in suffer from numerous technical, organizational, land structural problems, which strongly undermine their performance. This the case of irrigated perimeter Karfiguéla...

BACKGROUND The success of endodontic treatment depends on a few crucial factors. One of these factors is the complete chemomechanic preparation of root canal against various bacteria. In particular, the effect of resistant bacteria may cause intense pain with flare-up and formation of periapical lesions. Therefore, the strong effect of irrigants plays an important role in terms of the complete ...
