The effectiveness of three sanitizers in killing Salmonella during room temperature storage with and without contaminating feces, egg, or chicken rinse for 48 h was tested. Uncontaminated sanitizers were tested, as were 50-mL solutions of 0.035% polyhexamethylenebiguanide hydrochloride (PHMB), 0.39% (1:256) Tektrol, and 1.4% H2O2, which were contaminated with 10 mL of a feces slurry, 10 mL of m...

BACKGROUND Due to the increasing rates of oropharyngeal cancer, oral HPV infection is a significant concern. Methods for detecting oral HPVs is not standardized as there are different techniques available. We propose that use of oral rinse samples to detect for HPVs is a suitable technique within a clinic setting. Thus, our main objective is to study HPV detection in oral rinse samples. METHO...

BACKGROUND The use of electric current during application of etch-and-rinse adhesive systems has been recently introduced to decrease microleakage. This study investigated the effects of an electric field produced by an experimental device for the application of a two-step etch-and-rinse adhesive on moist dentin surface. METHODS Sixty freshly extracted human premolars were used for this study...

OBJECTIVES To test the short term clinical effectiveness of commercially available 0.07%.cetylpyridinium chloride mouth rinse in patients undergoing fixed orthodontic treatment as compared to a placebo mouth rinse and patients using toothbrush and toothpaste. METHOD Forty-five subjects for this double blind study were assigned randomly into three groups of 15 each. Gingival inflammation, plaq...

Our experiment evaluated the microleakage in resin composite restorations bonded to dental tissues with different adhesive systems. 40 class V cavities were prepared on the facial and lingual surfaces of each tooth with coronal margins in enamel and apical margins in cementum (root dentin). The teeth were restored with Z100 resin composite bonded with different adhesive systems: Scotchbond Mult...

Oral mucositis is a common morbidity induced by radiation therapy and chemo-radiotherapy for head and neck malignancies. This often results in treatment delays, premature treatment cessation and increased cost. New treatments of oral mucositis are emerging but effective remedies remain limited. Between February 2007 and May 2008, 21 patients with head and neck malignancies were treated with a s...

OBJECTIVE Calcium fluoride deposit during fluoride application. Uptake and retention of fluoride by saliva depends generally on the concentration of calcium. In this study, the effect of calcium pre-rinse on salivary fluoride concentration after a 900 ppm fluoride mouthwash was investigated. MATERIALS AND METHODS This cross-over double-blind randomized clinical trial was conducted in a girls'...

BACKGROUND Kathon CG is a commonly used cosmetic-grade preservative that contains active ingredients methylchloroisothiazolinone (MCI) and methylisothiazolinone (MI). OBJECTIVE The aim of the study was to perform a skin sensitization induction risk assessment of daily exposure to Kathon CG after use of various personal care and cosmetic products. METHODS We calculated an estimated daily con...

Sampling techniques are combined during bronchoscopy to increase the diagnostic yield for endobronchial malignant tumours. Bronchial biopsy provides the definitive histological diagnosis in most cases, but accompanying cytological procedures such as washing, brushing, needle aspiration or imprint cytology can increase diagnostic yield. In this prospective study, a different cytological techniqu...

The present study examined intraluminal events in the in vivo processing of a protein antigen by the intestine of normal and orally immunised rats. One hour after the administration of 125I-bovine serum albumin (1251-BSA) and unlabelled BSA by gavage, the majority of the radioactivity was found in the distal small intestine of control and immunised rats but there was-a difference in the distrib...
