Even with improved systems of working length measurement, different readings may be recorded in different electrolytes present in the canal. The purpose of this in vivo/ex vivo comparative study was to determine the accuracy in measuring the working length of root canal using Direct Digital Radiographic Method (Radiovisiography or RVG) and ProPex electronic apex locator in the presence of three different irrigating solutions: 0.9% normal saline, 2% chlorhexidine, 3% NaOCl solutions. Forty single-rooted human teeth scheduled for extraction with mature apices were selected for this study. Measurements were performed by using RVG and ProPex in the presence of irrigating solutions. After extraction of the teeth, light microscope was used to confirm visually the relationship of the tip of the endodontic file to the apical foramen, and actual lengths were determined by reducing 0.5 mm from this...

There are surgical and nonsurgical methods to treat such cases. Ideally, a nonsurgical method should initially be done especially in cases where lesions are in close proximity to important anatomical landmarks. The success of the nonsurgical endodontic treatment method is based on appropriate cleaning, shaping, asepsis and filling of the root canal. Studies have reported a success rate of up to 85 % after endodontic treatment of teeth with periapical lesions. Various methods can be used in the nonsurgical treatment: Decompression technique, Aspiration-Irrigation technique, Method using calcium hydroxide, Lesion Sterilization and repair therapy and the Apexum procedure. Monitoring the healing of periapical lesions is essential through periodic follow-up examination. Key words: Cyst, decompression, healing, LSTR therapy, heali...

Past efforts have been aimed at eliminating the bacterial challenge and creating an environment conducive to the placement of a root canal filling. The infection of the root canal system is considered to be polymicrobial infection, consisting of both aerobic and anaerobic bacteria. Because of the complexity of the root canal infection, it is unlikely that any single antibiotic could result in effective sterilization of the canal. A combination of antibiotic drugs (metronidazole, ciprofloxacin and minocycline) is used to eliminate target bacteria, which are possible sources of endodontic lesions. Two case reports describe the nonsurgical endodontic treatment of teeth with large periradicular lesions. During treatment procedure, 2.5% sodium hypochlorite was used for irrigation and a combination of antibiotic drugs was used for the int...

Materials and Methods: An epidemiological survey was conducted to assess oral hygiene status and prevalence of dental caries among 3-14 years old specially abled children attending various special schools for specially abled in Mathura district, India. A total of 200 children which included 95 female and 105 male students were examined. According to nature o f handicap, they were divided into following groups: (1) Deaf and Dumb (2) Mentally retarded(MR) (3 Down’s syndrome group (4) Learning disability (LD) and (5) Complex group (children wit h more than one handicapping condition/disability).A survey profoma prepared wit h the help of WHO oral health assessment form (1997) was used, Oral hygiene status was assessed u sing OHI-Simplified given by (Greene and Vermilion 1964) and dental caries was...

The treatment requires high patient compliance, multiple appointments extending over a long period of time and relatively high pH of the material that compromise the strength of the root dentin. 2

The statistical analysis was performed by one-way ANOVA test and Tukey-HSD post hoc procedure. P < 0.05 was considered as significant.Results:No significant difference was found between overall mean electronic working length and digital radiographic length; however, prediction error (P < 0.05) was significant with respect to different irrigants. Among the irrigating solutions, chlorhexidine gluconate had the smallest distance to the actual lengths, whereas NaOCl had the greatest.Conclusion:Electronic apex locator ProPex yielded best result in the presence of chlorhexidine, whereas the largest error was demonstrated with NaOCl indicating that higher electroconductive irrigating solutions affect the precision of multi-frequency apex locators.
