Preparation of root canal systems includes both enlargement and shaping of the complex endodontic space together with its disinfection. A variety of instruments and techniques have been developed and described for this critical stage of root canal treatment. Although many reports on root canal preparation can be found in the literature, definitive scientific evidence on the quality and clinical...

The endodontic triad comprises of cleaning and shaping, disinfection and obturation. Success of root canal therapy is majorly achieved by proper cleaning and shaping. However, elimination of bacterial contaminants as well as necrotic debris of the canals requires the adjunctive use of irrigants. To achieve a satisfactory biological and mechanical preparation proper selection of endodontic instr...

AIM To determine the antimicrobial effect of water extracts of leaves of Annona muricata and Simarouba glauca on Enterococcus faecalis using agar diffusion method. MATERIALS AND METHODS Dried leaves of A. muricata and S. glauca were powdered and extracted in a soxhlet apparatus. Enterococcus faecalis was grown overnight in Trypticase soy agar plates. About 10 μl of each extract was placed on ...

The aim of this review is to give a survey of the use of high-power lasers for root canal cleaning and disinfection. There are two approaches: the first using a fiber in a dry root canal and exposing the root canal wall to the laser light with a spiral motion, and the other using the fiber in irrigant in the root canal or at the orifice. The laser-target interaction is different: a direct expos...

Background: Disinfection and sterilization of obturating materials in the root canal is necessary for the successful root canal therapy. Various disinfectants have been used to sterilize and disinfect gutta‐ percha including sodium hypochlorite (NaOCl), chlorohexidine (CHx), etc. . Effectiveness of peracetic acid over NaOCl is documented in literature, but no study to date has shown the effect ...

OBJECTIVES To evaluate clinically and radio graphically, the healing following nonsurgical treatment of periapical lesions when Photo Activated Disinfection(PAD), triple antibiotic paste and calcium hydroxide was used as root canal disinfectant. MATERIAL AND METHODS Sixty patients (20 for PAD, 20 for triple antibiotic paste, 20 for calcium hydroxide) with periapical lesions in the maxillary a...

Introduction As the root canal system considered to be complex and unpredictable, using root canal irrigants and medicaments are essential in order to enhance the disinfection of the canal. Sodium hypochlorite is the most common irrigant in endodontics. Despite its excellent antimicrobial activity and tissue solubility, sodium hypochlorite lacks some important properties such as substantivity a...

Endodontic posttreatment pain remains to be a significant problem facing the dental profession. Antibacterial intracanal dressing has been advocated to eliminate remaining bacteria after chemomechanical preparation.1 Various intracanal medicaments are advocated to eliminate bacteria and prevent multiplication of bacteria between the appointments. Calcium hydroxide (CH) has been the most commonl...

Figure 1b: A 10-year post-treatment radiograph reveals excellent healing and confirms the importance of treating root canal systems. Introduction There are enormous differences in opinion regarding the potential to 3-dimensionally clean a root canal system. Elimination of pulpal tissue, bacteria (when present), and their related breakdown products is directly influenced by a series of procedura...
