Factors affecting apically extrusion debris during root canal treatment -A literature review

Nano Science and Root Canal Therapy: A Literature Review

Nano science and nanotechnology have revolutionized all aspects in the endodontic field. The aim of the present study was to describe the application of nanotechnology in endodontics by reviewing the literature.The application of nanomaterials, with a smaller size, for surface modification has reduced the incidence of failure in the rotary nickel-titanium files. Nanoparticles with the ability o...

Factors affecting outcome of non-surgical root canal treatment

Retreatment versus initial root canal treatment: factors affecting posttreatment pain.

OBJECTIVE The purpose of this study was to determine the factors associated with posttreatment pain in patients receiving root canal retreatment (RCR) and in those receiving initial root canal treatment (IRCT). STUDY DESIGN Eighty four patients scheduled for RCR or IRCT completed questionnaires on pretreatment pain levels (Visual Analogue Scale, 0-100) and demographic data. Diagnosis and orig...

Reciproc versus Twisted file for root canal filling removal: assessment of apically extruded debris

PURPOSE The aim of this study was to evaluate the amount of apically extruded debris during endodontic retreatment with different file systems. MATERIALS AND METHODS Sixty extracted human mandibular premolar teeth were used in this study. Root canals of the teeth were instrumented and filled before being randomly assigned to three groups. Guttapercha was removed using the Reciproc system, the...

In Vitro Comparison of Apically Extruded Debris during Root Canal Preparation of Mandibular Premolars with Manual and Rotary Instruments.

Background and aims. During root canal preparation, debris extruded beyond the apical foramen may result in periapical inflammation and postoperative pain. To date no root canal preparation method has been developed that extrudes no periapical debris. The purpose of this study was to identify a system leading to minimal extrusion of debris from the apical foramen. The study was conducted to com...
