Treatment of chemical bums requires rapid dilution of the chemical, decreasing eye exposure to the toxic material. Prolonged exposure to the chemicals can lead to decreased visual acuity, and even loss of the eye (Pfister, 1983). ffighly caustic compounds can be found in industry and agriculture, as well as at home (Duane, 1981). Alkalies are usually more damaging than acids, due to rapid penet...

We studied the effects of intraocular irrigating solutions on the 30Hz flicker electroretinogram (ERG) during extracapsular cataract surgery in 45 eyes of 35 patients. The effects of two commercially available irrigating solutions. S-MA2 (Opeguard MA) and DE-057 (BSS Plus) were compared. After irrigation and aspiration (I/A) of the residual cortex with S-MA2, ERG amplitude increased to 111.2 +/...

PURPOSE To evaluate the influence of irrigation of the anterior chamber with heparin sodium on postoperative inflammation after pediatric cataract surgery. SETTING Kartal Training and Research Hospital, First Eye Clinic, Istanbul, Turkey. DESIGN Randomized prospective double-blind study. METHODS Fourteen consecutive eyes from 14 patients aged 8.9 +/- 5.9 years, (range 3-18 years) (group 1...

solutions with a new experimental chelating solution in infected dentin tubes. Twenty-five specimens were randomly assigned to each of the irrigating solutions. Twenty specimens were used as negative and positive controls. After 21 days of contamination with E. faecalis, the irrigating solutions MTAD, QMiX and Tetraclean NA were delivered into each infected root canal. The solutions were remove...

The objective of this study was to evaluate the influence of irrigants on the antimicrobial potential of calcium hydroxide paste in dogs' teeth with apical periodontitis. Forty-eight premolar teeth of adult mongrel dogs had their root canals opened to the oral environment for 6 months. The root canals were prepared and treated with different irrigating solutions and intracanal medicaments, acco...

Root canal irrigants play a significant role in the elimination of microorganisms, tissue dissolution, and the removal of debris and smear layer. Sodium hypochloride is the most commonly used endodontic irrigant, despite limitations. None of the presently available root canal irrigants satisfy the requirements of ideal root canal irrigant. Newer root canal irrigants are studied for potential re...

OBJECTIVE The purpose of this study was to evaluate by scanning electron microscopy (SEM) the removal of smear layer from the middle and apical root thirds after use of different irrigating solutions. MATERIAL AND METHODS Forty roots of permanent human teeth had their canals instrumented and were randomly assigned to 4 groups (n=10), according to the irrigating solution: apple vinegar (group ...

INTRODUCTION Root canal disinfection is an important step in regenerative endodontic treatments. An ideal irrigating solution must have high antimicrobial activity and minimum cytotoxicity. This study sought to assess the effect of some irrigating solutions on stem cells from the human apical papilla (SCAP) after different periods of exposure. METHODS AND MATERIALS Stem cells were isolated fr...

AIM To evaluate the cytotoxicity of 15% citric acid, 5% phosphoric acid and 2.5% NaOCl on cultured fibroblasts using MTT colorimetric assay. METHODOLOGY Irrigating solutions of 5% phosphoric acid, 15% citric acid, and 2.5% NaOCl, diluted at 0.1% and 0.5%, were applied to cell cultures of 3T3L1 fibroblasts. The cell viability was determined by means of MTT colorimetric assay after a period of ...

The aim of this study was to evaluate the influence of irrigating solutions commonly used during endodontic treatment on the push-out bond strength of intrarradicular fiber posts to dentin. Thirty single rooted teeth were divided into 3 groups according to the solution used during instrumentation: G1, NaOCL 5.25%; G2, 2% chlorhexidine; G3, distilled water. The root canals were prepared and obtu...
