INTRODUCTION This study aimed to compare the efficacy of MTAD, Glyde and EDTA in removing the post-preparation smear layer and debris produced in apical third of curved molar root canals. MATERIALS AND METHODS Forty extracted human maxillary first molars with curved mesiobuccal canals (30˚-35˚), similar root lengths and morphologies were divided into 3 experimental groups (n=12) and one contr...

INTRODUCTION To compare the cleaning effectiveness of K3 and Race NiTi rotary systems with K-Flexo file instruments during the preparation of curved canals in extracted human teeth. MATERIALS AND METHODS A total of 50 root canals of mandibular and maxillary molars with curvatures ranging between 25º and 35 º were divided in three groups of 15 each and 5 as negative control groups. Canals were...

BACKGROUND AND OBJECTIVES Previous research has examined patients' attitudes toward use of exam room computers by physicians. Our objective was to determine patient attitudes toward physicians' exam room use of new tablet computers. METHODS A random sample of 96 patients was interviewed immediately following a visit to a physician at an outpatient family medicine clinic at a large academic me...

INTRODUCTION This study compared the cleaning efficiency of Mtwo, Race and Medin Nickel-Titanium (NiTi) rotary instruments. MATERIALS AND METHODS Sixty mandibular molar mesial roots were selected with angle curvatures between 25-35 degrees and divided into three groups; each containing 20 teeth. Canals were prepared with the rotary files and irrigated with 2.5% NaOCl solution after each instr...

This paper presents selected results from the Administrative Records Experiment in 2000 (AREX 2000). AREX 2000 used administrative records to enumerate the population in two test sites and compared the results to Census 2000. The test sites included two Maryland and three Colorado counties that offered distinct challenges to the enumeration process. The Outcomes Evaluation assessed two enumerat...

INTRODUCTION AND OBJECTIVE The aim of this study was to evaluate the ability of root canal cleaning of the RaCe rotary instrumentation system (FKG Dentaire - La-Cheaux-de Fonds - Switzerland), compared to manual filing with Stainless Steel K-files (Maillefer Instruments - Ballaigues - Switzerland). MATERIAL AND METHOD Twenty extracted human teeth (maxillary molars) were selected and their pul...

the fungal disease, ascochyta blight, caused by ascochyta rabiei is a major yield limiting factor of chickpea (cicer arietinum l.) in many countries, including iran. identification of resistance sources against races or pathotypes of the fungus causing this disease is required for breeding resistant chickpea cultivars. reaction of six selected genotypes of iranian chickpea collection was evalua...
