Objectives: The present study aims to identify radiographic methods revealing data that are most representative for the true peri-implant bone as assessed by histology. Materials and methods: Eighty implants were placed in 10 minipigs. To assess matching between different image modalities, measurements conducted on intra-oral digital radiographs (IO), cone beam computer tomography (CBCT) histological images correlated using Spearman's correlation. Paired tests (Wilcoxon test) used determine...
To investigate voids in different root canal sealers using micro-CT and nano-CT, to explore the feasibility of nano-CT for quantitative analysis sealer filling quality.
The purpose of this study was to analyze the ability multiple compounds seal dental tubules using scanning electron microscopy (SEM) and micro-computed tomogra-phy (micro-CT).Twenty-four single-root human mandibular premolars were selected instrumented with nickel-titanium rotary file final size #40/06. They then randomly allocated into 2 groups, all samples filled single cone gutta-percha (#40/06) one tested sealers (AH Plus EndoSequence BC sealers). All specimens scanned micro-CT three...
Article abstract-We investigated the mechanisms of muscle fatigue in ALS. In muscles ALS patients and healthy control subjects, we examined (1) using measurements force, (2) energy metabolism phosphorus-31 magnetic resonance spectroscopy, (3) activation neurophysiologic measures MRI. During 25 minutes intermittent isometric exercise tibialis anterior muscle, both maximum voluntary tetanic force declined more than controls, indicating greater fatigability There was a similar decline...
Early detection of marginal bone loss is vital for treatment planning and prognosis teeth implant. This study was conducted to assess diagnostic accuracy CBCT compared intra-oral (IO) radiography detection, classification, measurement peri-implant defects in an animal model.Fifty-four mandible blocks with implants were harvested from nine male health adult beagle dogs acquisition IO, micro-CT images all samples. Peri-implant 16 samples diagnosed using classified into 3 defect categories:...
While several materials and techniques have been used to assess the quality of root canal fillings in micro-CT images, lack standardization scanning protocols has produced conflicting results. Hence, aim this study was determine a cutoff voxel size value for assessment filling voids nano-CT images. Twenty freshly extracted mandibular central incisors were used. Root canals prepared with nickel titanium files an ISO 40/0.06 taper then filled single cone (40/0.06 taper) AH Plus sealer. The...
Background and purpose The aim was to investigate whether abnormal TTTTA TTTCA repeat expansions in introns of SAMD12 , TNRC 6A RAPGEF 2 are involved the pathogenesis familial cortical myoclonic tremor with epilepsy ( FCMTE ). Methods Five families diagnosed were included current genetic analysis. Whole‐exome sequencing performed selected patients each family. examined by repeat‐primed polymerase chain reaction. clinical features elicited as defined common mechanism 14 patients. Results...
Although neurophysiological and psychophysical proof of osseoperception is accumulating, histomorphometric evidence for the neural mechanisms functional compensation following immediate delayed implant loading still lacking. For this randomized split-mouth study, six mongrel dogs randomly received one four treatment protocols at 36 implant-recipient sites over 16 weeks (third maxillary incisor, third fourth mandibular premolar): placement (IIP+IL); (DIP+DL); (DIP+IL); natural extraction...
Near-stoichiometric lithium tantalate (NSLT) wafers with different Li contents were prepared by vapour transfer equilibrium (VTE) method and fabricated into surface acoustic wave filters. The temperature coefficient of frequency, insertion loss, bandwidth the filters tested using a special chip test bench network analyzer. results show that frequency shows trend first decreasing then increasing increase in content, stability is best when content 49.75%. It also found filter from NSLT has...
Lithium tantalate crystals, as a type of pyroelectric material, stand out from many other materials due to the advantages high Curie temperature, large coefficient, figure merits, and environmental friendliness. Due effect caused by their spontaneous polarization, lithium crystals have broad application prospects in wide spectral bandwidth uncooled detectors. This article reviews properties evaluates methods for properties, modulating detectors applications. The thin films, doped near...
Cone-beam computed tomography (CBCT) has been recently used to analyse trabecular bone structure around dental implants. To validate the use of CBCT for three-dimensional (3D) peri-implant morphometry by comparing it two-dimensional (2D) histology, 36 alveolar samples (with implants n=27 vs. without n=9) from six mongrel dogs, were scanned ex vivo using a high-resolution (80 µm) CBCT. After scanning, all decalcified and then sectioned into thin histological sections (∼6 μm) obtain high...
To evaluate the peri-implant trabecular bone volume and architecture changes with 6-month follow-up after local application of platelet-rich plasma (PRP) platelet-poor (PPP) using high-resolution micro-CT.Seventy-two dental implants were placed into healed mandibular sites 9 beagle dogs. Implants randomly divided 4 groups following a split-mouth design: control I; II; PPP; PRP. Primary secondary stabilities assessed resonance frequency analyses. At 1, 3, 6 months implant loading, structural...
Abstract Purpose To develop a method for characterizing trabecular bone microarchitecture using cone beam computed tomography ( CBCT ) and to evaluate changes after rehabilitation immediate versus delayed implant protocols. Materials Methods Six mongrel dogs randomly received 27 titanium implants in the maxillary incisor or mandibular premolar areas, following one of four protocols: (1) normal extraction socket healing; (2) placement loading; (3) (4) loading. The animals were euthanized at 8...
