The purpose of this study was to evaluate the effectiveness of various chemical disinfectants in decontamination of gutta-percha (GP) cones contaminated with Bacillus subtilis spores. Sodium hypochlorite solution (4%), glutaraldehyde solution (2%), povidone-iodine solution (5%), and savlon solutions were compared for effectiveness in sterilizing gutta-percha cones contaminated with Bacillus sub...

To the Editor—We read with great interest the articles by Noorani et al in the British Journal of Surgery and by Lee et al in Infection Control and Hospital Epidemiology. The authors have published almost simultaneously two systematic reviews of what is described as comparisons of chlorhexidine versus povidone-iodine for preoperative skin antisepsis. On the basis of their analyses, the authors ...

Background and Aim: Bacterial colonization occurs following contamination of impression materials with blood and saliva. However, not all disinfecting agents are compatible with the impression materials and may cause changes in the resultant casts. The purpose of this study was to assess the impact of various immersion time of addi-tion silicon impressions in different disinfecting solutions on...

Materials and Methods: The subjects were 36 systemically healthy, non-smoking patients (34-66 years old). All patients presented moderate-to-advanced chronic periodontitis and had at least 5 teeth and 2 pocket sites with probing depth ≥ 5 mm in each quadrant and bone loss. Then, they were randomly distributed to 3 different groups. 1. conventional quadrant-wise mechanical debridement (QMD): sup...

No data exists on the activity of biocides (antiseptics and disinfectants) on Rhinosporidium seeberi that causes rhinosporidiosis in humans and animals. On account of the inability to culture R. seeberi, in vitro, dyes were used to assess the morphological integrity and viability of biocide-treated endospores that are considered to be the infective stage of this pathogen. Evan's Blue (EvB) iden...

background and objectives: hand hygiene is a crucial measure for preventing healthcare-related infections. surgical scrub is an important factor in the safety and success of a surgical operation. the aim of this study was to comparatively evaluate effectiveness of some conventional surgical antiseptic solutions, and to identify the most effective one. methods: effectiveness of alcohol-based sol...

For author affiliations and current addresses, see end of text. C of blood cultures is common because microflora are usually present on the skin. The misinformation that results from contamination of blood cultures may have deleterious consequences. Therefore, it is important that blood cultures be collected by using a procedure that minimizes contamination (1). In general, preparation of the s...

To the Editors:Your concerns regarding the recently published study, ‘‘A randomized trial that compared povidone iodine and chlorhexidine as antiseptics for vaginal hysterectomy,’’ are appreciated. First, by way of clarification, the literature search to which you refer did retrieve studies in which vaginal chlorhexidine had been used. In fact, we found 3 studies (including a total of more than...

AIM to investigate the effectiveness of 10% povidone-iodine after a 30-second or 2-minute drying time on microbial count reduction at the point of a Peripheral Intravascular Catheter (PIC) insertion. A quasi-experimental design was adopted. In total, 53 patients were enrolled, 25 were exposed to a 2-m drying time and 28 to a 30-s drying time. From the preliminary results of this study, no diffe...
