Teeth And Root Canals Segmentation Using ZXYFormer With Uncertainty Guidance And Weight Transfer [PDF]
arXiv, 2023 This study attempts to segment teeth and root-canals simultaneously from CBCT images, but there are very challenging problems in this process. First, the clinical CBCT image data is very large (e.g., 672 *688 * 688), and the use of downsampling operation will lose useful information about teeth and root canals.

Quantitative microleakage analysis of root canal filling materials in single‐rooted canals
Scanning, 2015 SummaryThe purpose of this study was to analyze the sealing ability of different root canal filling materials over a 6‐week period using a glucose penetration model. Forty‐six recently extracted human premolars were used in this study. The root canals were enlarged to 40/0.06. Prepared canals were randomly assigned into four groups (n = 10) as follows:

AGMB-Transformer: Anatomy-Guided Multi-Branch Transformer Network for Automated Evaluation of Root Canal Therapy [PDF]
arXiv, 2021 Accurate evaluation of the treatment result on X-ray images is a significant and challenging step in root canal therapy since the incorrect interpretation of the therapy results will hamper timely follow-up which is crucial to the patients' treatment outcome. Nowadays, the evaluation is performed in a manual manner, which is time-consuming, subjective,

Developments in ROOT I/O and trees [PDF]
J.Phys.Conf.Ser.119:042006,2008, 2009 For the last several months the main focus of development in the ROOT I/O package has been code consolidation and performance improvements. Access to remote files is affected both by bandwidth and latency. We introduced a pre-fetch mechanism to minimize the number of transactions between client and server and hence reducing the effect of latency.

Histopathological evaluation of root canal filling materials for primary teeth [PDF]
Brazilian Dental Journal, 2010 This study aimed to assess the response of apical and periapical tissues of dogs' teeth after root canal filling with different materials. Forty roots from dogs' premolars were prepared biomechanically and assigned to 4 groups filled with: Group I: commercial calcium hydroxide and polyethylene glycol-based paste (Calen®) thickened with zinc oxide ...

Optimizing the vertebrate vestibular semicircular canal: could we balance any better? [PDF]
, 2004 The fluid-filled semicircular canals (SCCs) of the vestibular system are used by all vertebrates to sense angular rotation. Despite masses spanning seven decades, all mammalian SCCs are nearly the same size. We propose that the SCC represents a sensory organ that evolution has `optimally designed'. Four geometric parameters are used to characterize the

Field canalization using anisotropic 2D plasmonics [PDF]
arXiv, 2021 Optical devices capable of suppressing diffraction nature of light are of great technological importance to many nanophotonic applications. One important technique to achieve diffractionless optics is to exploit field canalization effect. However, current technological platforms based on metamaterial structures typically suffer from strict loss ...

HL-LHC Analysis With ROOT [PDF]
arXiv, 2022 ROOT is high energy physics' software for storing and mining data in a statistically sound way, to publish results with scientific graphics. It is evolving since 25 years, now providing the storage format for more than one exabyte of data; virtually all high energy physics experiments use ROOT. With another significant increase in the amount of data to
