This study evaluated the presence of residual root canal filling material after retreatment using micro-computed tomography (micro-CT).Extracted human teeth (single- and double-rooted, n = 21/each; C-shaped, 15) were prepared with ProFile randomly assigned to three subgroups for obturation gutta-percha different sealers (EndoSeal MTA, EndoSequence BC sealer, AH Plus). After 10 days, was removed canals instrumented one size up from previous master apical file size. The scanned micro-CT before...
The objective of this study was to evaluate the association between overweight, obesity and incidence advanced dental caries in South Korean adults, using alternate measures. participants included 376,077 people aged 20 years older who had health examination at least one time 2005 2008. This evaluation is based on a change body mass index (BMI) category, for 10 years, nationally representative data resource available from National Health Insurance System. Instead decayed, missing, filled...
Summary The purpose of this study was to analyze the sealing ability different root canal filling materials over a 6‐week period using glucose penetration model. Forty‐six recently extracted human premolars were used in study. canals enlarged 40/0.06. Prepared randomly assigned into four groups (n = 10) as follows: Group 1, Gutta‐Percha (GP)/AH Plus with cold lateral compaction; 2, GP/AH continuous wave 3, RealSeal SE obturation system; and 4, OrthoMTA. remaining specimens positive negative...
This study introduces a hybrid model that combines physics and machine learning (ML) models to describe the behaviour of variable refrigerant flow (VRF) systems. The standalone ML was developed with identical data conditions for comparison between models. A Bayesian neural network (BNN) used both models, predictive abilities uncertainties were investigated. For experimental dataset, performances similar. example, performance showed mean absolute error 0.73 0.78 kW, respectively. However,...
This study investigated the retreatability of EndoSeal MTA (Maruch, Wonju, Korea) according to presence or absence a canal isthmus and additional use passive ultrasonic irrigation (PUI) through microcomputed tomography (micro-CT) imaging. An epoxy resin sealer (AH Plus (Dentsply DeTrey, Konstanz, Germany)) was used as reference for comparison. Forty-five artificial mandibular molars (TRUETOOTH #19, DELABS, Santa Barbara, CA) with mesial an distal without were obturated using gutta-percha one...
엔진의 출력증대와 이에 따른 변속기의 크기 증가 등으로 인한 회전체의 관성증가로 변속성능은 악조건이 되고 있다. 따라서, 이를 해결하기 위하여 내마모성이 높은 마찰소재의 개발이 요구된다. 디젤차량 수동변속기용 싱크로나이저 링에 요구되는 마찰특성에 적합한 소재를 개발하고, 대한 접합 특성을 평가하였다. 즉, 철합금 모재와 동합금계 마찰재를 접합하는 공정을 접합층에 대하여 BSE분석, EDX분석을 수행하여 접합특성을 평가하였으며, 해당 시험편에 전단강도를
‐ Abstract Study Design : The relationships between aorta and thoracic vertebrae were analyzed by using MR images. Objectives purpose of this study was to provide information upon the aortic passage prevent vascular complications during anterior posterior instrumentations for various spinal disorders traumas. Summary Background Data: A number morphometric investigations have been performed on vertebrae, but anatomical relationship vertebral body has not analyzed. Methods images 32 patients...
