INTRODUCTION Although it is apparent that teeth become more susceptible to fracture after root canal treatment, the contributing factors for this are not completely established. The purpose of this study was to determine whether there are changes in nanomechanical properties of dentin in root canal-treated teeth compared with non-root canal-treated control teeth. METHODS Atomic force microsco...

Procedure Following nonsurgical root canal treatment, a post space is created in the root canal by careful removal of the coronal canal obturating material. A sufficient amount of material must be retained in the apical portion of the canal to maintain an adequate apical seal. A custom or proprietary post is fitted and cemented into the root canal for core retention. The post should be passivel...

The success of the endodontic treatment depends on the removal of vital or necrotic pulp tissue and minimizing the amount of pathological debris from the complex root canal system. Root canal irrigation seems to be undeniably important during biomechanical preparation, particularly because, during mechanical instrumentation, approximately 35-40% of the root canal surface remained unchanged (1)....

Microbiota are found in highly organized and complex entities, known as biofilms, the characteristics of which are fundamentally different from microbes in planktonic suspensions. Root canal infections are biofilm mediated. The complexity and variability of the root canal system, together with the multi-species nature of biofilms, make disinfection of this system extremely challenging. Microbia...

BACKGROUND Root canal preparation using rotary nickel-titanium instruments has been reported to be superior to hand instrumentation in terms of root canal shape, centring and frequency of procedural errors. The purpose of this study was to evaluate canal preparations using a sequential silicone impression technique to assess root canal morphology. METHODS Pre-operative canal impressions were ...

AIM The purpose of this study was to test a new root canal sealer (Epiphany) and 5 other root canal sealers (Diaket, Endomethasone, AH 26, Sealapex, Sultan) for their antimicrobial effect on Enterococcus faecalis. MATERIALS AND METHODS The antimicrobial effect of 6 root canal sealers was tested by the agar diffusion method. The freshly mixed sealers were placed in prepared wells of agar plate...

Mandibular premolars are known for their aberrant root canal variations. This is because, they are highly unpredictable and often present with a wide variety of morphological variations. Slowey et al. reported that these root canal aberrations in mandibular premolars present an endodontic challenge to the dental practitioners.Hence, these teeth may require skillful and careful root canal prepar...

Successful root canal therapy requires a thorough knowledge of root anatomy and root canal morphology which may be quiet variable. The significance of internal root canal morphology has been emphasized by studies demonstrating that variations in canal morphology may affect the endodontic outcome. Consequently, in treating each tooth the clinician must assume that complex anatomy occurs often en...

BACKGROUND The aim of the study was to identify the number of root canals and examine root canal morphology of permanent mandibular incisors in an Indian sub-population of Pune, Maharashtra, India using cone-beam computed tomography (CBCT). MATERIAL/METHODS This study was conducted at Elite CBCT & Dental Diagnostics, Pune. One hundred mandibular incisors were evaluated for the number of root,...

a detailed knowledge of root canal anatomy is a prerequisite for successful endodontic treatment. such information is highly dependent upon the ethnicity of the population of interest. lack of sufficient national information concerning internal anatomy can lead clinicians to increase their rate of treatment success. the aim of this study was to evaluate external root morphology and root canal a...
