objective: etching of enamel and dentin is an important step in restoration of teeth with composite resin ensuring the retention of restoration and decreasing microleakage. this in vitro study sought to compare the effects of kimiya and etch-rite acid etchants on the microleakage of composite restorations.   methods: this experimental study was conducted on 30 sound human molar teeth. class v c...

PURPOSE To investigate the clinical significance of gallbladder (GB) wall thickening frequently observed in patients with acute hepatitis A. METHODS A total of 328 consecutive patients who were diagnosed with acute hepatitis A and underwent abdominal ultrasonography were enrolled retrospectively. Patients were divided into two groups: GB wall thickening (≥3 mm, group A) and no thickening (gro...

hepatomegaly, decrease in the liver paranchymal echo and increase in the gallbladder wall thickness has been shown in acute viral hepatitis. the present study was done to determine sonographic changes in acute viral hepatitis. we performed liver and bile ducts sonography and specific tests on 42 patients (mean age: 31.5 and 61% male) with acute viral hepatitis. gallbladder wall thickness was se...

purpose: to evaluate the efficacy of riboflavin administration and ultraviolet a (uva) cross-linking on advanced symptomatic bullous keratopathy (bk). methods: 10 patients with symptomatic pseudophakic bullous keratopathy (pbk) were included. slit-lamp examination, visual acuity, foreign body sensation (fbs) and corneal thickness as measured by pentacam, were performed before corneal cross-link...

background: there are two kinds of ascites, cirrhotic and malignant. the conventional diagnostic method to differentiate them is paracentesis. this is an invasive and time consuming method. however, ultrasonography is an easy and available method to provide valuable results in a short period of time. the aim of this study was to evaluate gallbladder wall thickness in differentiating cirrhotic a...
