Management of sodium hypochlorite extrusion beyond the root apex during root canal treatment: a case report.

Sodium hypochlorite (NaOCl) is most commonly used as an irrigating solution in endodontic practice. This paper describes an incident of sodium hypochlorite extrusion past the apex (SHEPA) of the UR3. Management of the condition resulted in hospitalisation of the patient, and intravenous antibiotic and steroid therapy.

Comparison of the efficacy of maleic acid and ethylenediaminetetraacetic acid in smear layer removal from instrumented human root canal: a scanning electron microscopic study.

Introduction: The aim of this study was to assess, by scanning electron microscopic (SEM) analysis, the ability of 17% EDTA and 7% maleic acid in the removal of the smear layer from the human root canal system.

Methods: Eighty single-rooted human anterior teeth were subjected to standardized root canal instrumentation (step-back technique) and were irrigated with 2.5% NaOCl after each instrument.

Clinical and microbiological profile of nosocomial infections in the pediatric intensive care unit (PICU).

This study was conducted in PICU of a teaching hospital to estimate the incidence of nosocomial infections, establish the clinical and bacteriological profile and identify probable exogenous source from the environment and personnel. 95 suspected cases of nosocomial infections were studied prospectively, identified as per the guidelines laid down by CDC. The rate of nosocomial infections was 27.
