Title of Thesis: In Vivo Evaluation of Contemporary Endodontic Antimicrobial Procedures Peter Bellingham, Master of Science, 2011 Thesis Directed by: Dr. Ashraf F. Fouad, Professor and Chairman, Director of Postgraduate Endodontics, University of Maryland School of Dentistry Introduction: Clinical assessment of the efficacy of novel root canal disinfection protocols is an important focus in end...

AIM To evaluate whether passive ultrasonic irrigation (PUI) of 2.5% NaOCl would dissolve necrotic pulp tissue from simulated accessory root canals (SACs) better than passive placement of the irrigant, when temperature was equilibrated between the two treatments. METHODOLOGY Transparent root canal models (n = 6) were made from epoxy resin. SACs of 0.2 mm diameter were placed at defined angles ...

BACKGROUND The present study aimed to evaluate the intracanal bacterial reduction promoted by chemomechanical preparation using three different herbal extracts named Ocimum sanctum (OS), Cinnamomum zeylanicum (CZ), Syzygium aromaticum (SA) against Enterococcus faecalis. MATERIAL AND METHODS Root canals from extracted teeth were contaminated with Enterococcus faecalis ATCC 29212 for 7 days and...

introduction : the aim of this study is to evaluate the effect of a newly introduced nanosilver based irrigant on dentin roughness in comparison with three commonly used root canal irrigants. material and methods : irrigants tested were: naocl 5.25%, edta 17%, chx 2% and newly introduced imidazolium-based silver nanoparticle (im agnp) irrigant at 5.8×10 -8 mol/l. distilled water was used as con...

IntroductionThe aim of this study is to report the management of large periapical lesion using triple antibiotic paste as an alternative intra-canal medicament in nonsurgical endodontic treatment. Case reportan 11 year old male patient with large periapical lesion in mandibular anterior region, treated using conservative non-surgical endodontic treatment. Calcium hydroxide-iodoform paste (Vitap...

PURPOSE The aim of this study was to evaluate the cytotoxic effect of a novel nano-silver particle (25.2±6.5 nm) endodontic irrigant (0.2 mM) and compare it with 3% sodium hypochlorite. MATERIALS AND METHODS Two cell types, mouse fibroblast National Institutes of Health 3T3 (NIH 3T3) and primary human periodontal ligament stem cell (hPDLSCs) were used in a test for the effect of direct and in...

Microorganisms play a major role in the initiation and perpetuation of pulpal and periapical disease. In order to predictably achieve a bacteria-free root canal system, it is necessary to use intracanal medicaments. Calcium hydroxide [Ca(OH)(2)] is the most common intracanal medicaments. It is effective against primary infections. However, its effectiveness against Enterococcus (E.) faecalis an...

Calcium hydroxide is used extensively as an intracanal medicament in endodontics for many years. It is used in various clinical situations such as to promote apexification, to repair perforation, to enhance healing of periapical lesions, to control root resorption, and to control exudation in teeth with persistent periapical inflammation. This paper presents a case report in which Ca(OH)2 was u...

Root canal treatment usually fails when treatment falls short of acceptable standards. The reason many teeth do not respond to root canal treatment is because of procedural errors that prevent the control and prevention of intracanal endodontic infection. In truth, a procedural accident often impedes or makes it impossible to accomplish appropriate intracanal procedures. Thus, there is potentia...
