materials and methods: eighty-four single rooted human teeth were randomly divided into 7 groups, 12 cases each, and canals were instrumented with mtwo rotary systems. 5.25% sodium hypochlorite, smear clear and 17% edta were used for irrigation of the canal during and/ or after instrumentation. after completion of instrumentation, all canals were dried with paper points and prepared to examine ...

BACKGROUND This study aimed to assess the push-out bond strength of mineral trioxide aggregate (MTA) to root canal dentin after irrigation with Smear Clear in comparison with 2.5% sodium hypochlorite (NaOCl), 2% chlorhexidine (CHX) and saline as commonly used root canal irrigants. MATERIAL AND METHODS The coronal and mid-root areas of maxillary anterior teeth were horizontally sectioned into ...

A 60-year-old postmenopausal female presented with complaints of heaviness in the abdomen associated with loss of weight and appetite. There were no urinary complaints or bleeding per vaginum. A vague mass was palpable in the lower abdomen measuring about 8x5 cm. Multiple bilateral inguinal lymph nodes were palpable. On per vaginal examination, a firm solid mass measuring 8x4 cm was felt throug...

DNA degradation (which results in a smear pattern) occurs with almost 50% of Mycobacterium abscessus strains during pulsed-field gel electrophoresis (PFGE). We assessed the potential benefit of using thiourea-containing buffer with M. abscessus by studying 69 isolates not previously typeable by PFGE (i.e., those with a smear pattern). Random (epidemiologically unrelated) isolates that were type...

INTRODUCTION Cervical cancer is one of the commonest cancers in women worldwide. Despite the existence of effective screening using Pap smear, the uptake of screening is poor. A qualitative study was undertaken using face-to-face in-depth interviews to investigate knowledge, attitudes and beliefs on cervical cancer screening of Malaysian women. METHODS In-depth interviews were conducted with ...

BACKGROUND The World Health Organization estimated in 2010 that 8.8 million new tuberculosis (TB) cases. About one-third of the world's population is infected and 10% will develop active TB disease. While cultures remain the international gold standard for diagnosing TB disease, in many other low-income countries, sputum smears remain the only and most accessible tool with which to diagnose act...

GeneXpert MTB/Rif assay for rapid diagnosis of tuberculosis and detection rifampicin resistance can reduce the time to initiation treatment. Aim. To evaluate sensitivity specificity compared with traditional methods detecting Mycobacterium (smear microscopy, culture on liquid solid media). Material methods. The results sputum tests (MBT) by bacteriological molecular genetic in 1355 patients dia...

A 49-year-old female was followed up at the gynecology clinic after conization for cervical cancer and underwent routine cervical smear, which revealed a cluster of adenocarcinoma cells. Positron emission tomography-computed tomography (PET-CT) showed increased FDG uptake around the proximal urethra. Urethroscopy showed a tumor arising from the urethral diverticulum, and it was revealed to be c...
