AIM To compare the efficacy of a standard NaOCl irrigation procedure with that of Er,Cr:YSGG laser irradiation in contaminated root canals having small and large apical foramina. METHODOLOGY Forty root canals of extracted central incisor teeth with straight roots were chosen so that their apical foramina just permitted the tip of a size 20-K file to pass(More)
OBJECTIVE This study compared the antibacterial activities of two dentin bonding systems (ABF, Kuraray and Reactmer Bond, Shofu) by a conventional agar well technique and a newly designed in vitro test using tooth model. METHODS In the agar well technique, the test materials were filled in the wells of Muller Hinton agar plates inoculated with(More)
Clostridium perfringens is a gram-positive, anaerobic bacterium that causes a wide range of diseases in humans and animals. Th e purposes of this study were to determine, using the enzyme-linked immunosorbent assay (ELISA), the clostridial toxins in intestinal samples of lambs with suspected enterotoxemia; to conduct molecular typing of C. perfringens(More)
This research, which was designed and carried out as two consecutive experiments, investigated the effects of four different levels (0, 4,000, 12,000, and 24,000 IU/kg) of vitamin A supplementation on egg yield, plasma vitamin A levels, and immune responses of laying hens. Transmission of maternal immunity to their descendants was also studied. In the first(More)
OBJECTIVE The aim of this in vitro study was to evaluate antibacterial activity of a new resin based sealer, EndoREZ in comparison with 5 other sealers: AH 26, Diaket, Sultan, Apexit, and RoekoSeal. STUDY DESIGN The effect of 6 different sealers on the growth of 3 bacteria (Enterococcus faecalis, Staphylococcus aureus, and Pseudomonas aeruginosa) was(More)
This paper reports on a study of the aetiology of calf pneumonia and the clinical efficacy of florfenicol, a new antibiotic in Turkey. Twenty-seven weaned and unweaned calves (13 males and 14 females) between 1 and 16 months of age brought to the clinics of Selçuk University, Faculty of Veterinary Science. Broncho-alveolar lavage (BAL) fluid samples were(More)
The objectives of the present study were to develop a dot-immunobinding assay (DIA) and a serum agglutination test (SAT) for detection of Ornithobacterium rhinotracheale, to compare the rapid agglutination test (RAT) and the SAT, and to make a serosurvey of O. rhinotracheale exposure on turkey farms in Turkey. Antiserum against O. rhinotracheale bacterin(More)
A total of 35 Escherichia coli isolates obtained from necropsy materials of hens with septicemia in the Konya region of Turkey were examined for hemagglutination (HA), cell-surface hydrophobicity, enterotoxigenicity, and drug resistance. HA tests were performed on live cultures with human (group A), bovine, avian (chicken), and guinea pig erythrocytes with(More)
The aim of the present study was to develop an in vitro test model from human teeth to comparatively examine antibacterial effectiveness of calcium hydroxide, parachlorophenol (PCP) and camphorated parachlorophenol (CPCP) against Enterococcus faecalis in infected root canals. Cylindrical dentin specimens were prepared from freshly extracted human maxillary(More)
