  ABSTRACT: The effect of intravenous aspirin on the exocrine pancreatic secretion was investigated in a feline isolated pancreaticoduodenal preparation. The study group received a 500 mg/kg bolus dose of aspirin intravenously. Duodenal washouts were collected for six hours. The serum and perfusate aspirin content increased significantly after aspirin administration (p = 0.01). However, the pH, bicarbonate, sodium, potassium and calcium content in the duodenal outflow did not show significant changes between 0 and 6 hours. A significant difference in the perfusate calcium content was present between ASA treated and control cats starting at the end of the first hour of the experiment (p=0.005). Histopathological examination of the pancreas revealed marked erythrocyte extravasation in the ASA treated animals. It is suggested that the ASA- related increase in the calcium secretion of the pancreas should be regarded as an indication of aspirin induced pancreatic damage.

• Article: Canal length evaluation of curved canals by direct digital or conventional radiography.

  ABSTRACT: The purpose of this study was to compare the accuracy of a digital radiograph imaging system (DDR) with conventional radiography for the purpose of estimating endodontic file lengths in curved canals of mandibular molars. Sixty extracted human mandibular molars with root curvatures ranging from 5 degrees to 52 degrees were mounted in plastic blocks. Canal length was estimated by using on-screen DDR with both 2- and 3-click measurement and from conventional E-speed radiographs by using a millimeter ruler and x2 magnification. Two operators familiar with both radiographic methods performed the estimates. One-way analysis of variance and Newman-Keuls tests revealed no significant differences between the groups. Although both conventional and DDR methods of analysis overestimated the true canal length, the DDR accuracy improved as the curvature severity increased. The image quality of DDR systems has improved to the point that they can now be used for estimating canal lengths, even for curved canals, with accuracy comparable to that of conventional radiographs. However, further work remains to be done to optimize image quality.

  ABSTRACT: The aim of the study was to evaluate toothbrushing management and ability of children in relation to age and gender. The study population consisted of 75 children and were divided into three equal groups as 3-5, 6-8 and 9-11 years of age. The grip type during toothbrushing was recorded on videotape, The most preferred grip types were distal (73%) followed by power (43%) and oblique grips (29%). There were a statistically significant differences between age groups and the grip types (p < 0.0041) but no significant difference was seen between boys and girls in grip preferences (p > 0.05). The mean duration of toothbrushing was shorter in 3-5 years of age group (28 seconds) than the 6-8 and 9-11 age groups (35 and 47 seconds respectively).
