BACKGROUND The main reason for the failure of endodontic therapy is the incomplete knowledge about the anatomical variation of root canals. One of the most important factors that leads to the failure of root canal treatment, is missed and untreated major root canals. OBJECTIVE with respect to the complexity of mandibular incisors treatment and high prevalence of the second canal, and the poss...

STATEMENT OF PROBLEM Little peer-reviewed information is available regarding the accuracy and reproducibility of digitally fabricated casts compared to conventional nondigital methods. PURPOSE The purpose of this in vitro study was to compare the accuracy and reproducibility of a digital impression and cast fabrication with a conventional impression and cast fabrication. MATERIAL AND METHOD...

Introduction: T2 relaxation time quantification has high potential for the diagnostic work up of cartilage, especially in early osteoarthritis. T2 calculation relies on fitting data acquired at different echo times (TE) from multi-echo sequences (MES) to an exponential equation, which is assumed to reflect transverse magnetization decay. The low T2 times in articular cartilage (between 10 and 5...

the present study was an attempt to investigate varieties of cloze test and c-test as measures of reading comprehension ability. it aimed at comparing the performances of subjects on different cloze and c-test forms constructed from the same passage. to this end, five versions of cloze test and two versions of c-test were developed by applying different deletion techniques and deletion rates, a...

Pisang Raja Bulu merupakan jenis pisang yang memiliki nilai ekonomis tinggi di Indonesia, oleh karena itu perlu dilakukan penelitian tanaman toleran atau resisten terhadap cekaman lingkungan salah satunya yaitu garam. Penelitian ini bertujuan untuk mengetahui konsentrasi NaCl tertinggi pada medium tidak mempengaruhi kandungan klorofil daun planlet Bulu; dengan demikian akan diperoleh garam seca...

objective: among the various impression materials, for alginate tear strength is probably more important than the compressive strength. the tear strength is important when an impression involves a mechanical undercut and/or lacks bulk strength to resist tearing. this study evaluated tear strength of iralgin and compared it with tear strength of alginoplast. methods: in this invitro experimental...

OBJECTIVES This study determined the flexural strength of one hipped and eight presintered zirconia and evaluated the results using different estimation methods of Weibull statistics. MATERIALS AND METHODS Presintered zirconia specimens were prepared in white state and sintered according to each manufacturer's instructions. One hipped zirconia acted as the control group. The specimens were lo...
