Trace element distribution in human teeth by x-ray fluorescence spectrometry and multivariate statistical analysis [PDF]

open access: yesarXiv, 2014
X-ray fluorescence spectrometry (XRFS) was used as a multielement method of evaluation of individual whole human tooth or tooth tissues for their amounts of trace elements. Measurements were carried out on human enamel, dentine, and dental cementum, and some differences in tooth matrix composition were noted.

Microtensile bond strength of resin-dentin bonds following application of a chemical collagen cross-linker using different dentin bonding systems [PDF]

open access: yes, 2015
Introduction: The stabilization of dentinal collagen fibers against enzymatic degradation by the use of biocompatible cross-linker agents is of clinical importance for effective dentin bonding to surpass the test of time.

Influence of desensitizing agents on the microshear bond strength of adhesive systems to dentin. [PDF]

open access: yesActa odontologica latinoamericana : AOL, 2009
The aim of this study was to evaluate the effect of desensitizing agents on the micro-shear bond strength of adhesive systems to dentin. Forty bovine teeth were divided into 8 groups (n=5): G1--Single Bond (SB); G2--GH.F + SB; G3-- Desensibilize + SB; G4--essensiv + SB; G5 --ingle Bond 2 (SB2); G6--H.E + SB2; G7--esensibilize + SB2; G8--Dessensiv + SB2.

Bitewing Radiography Semantic Segmentation Base on Conditional Generative Adversarial Nets [PDF]

open access: yesarXiv, 2018
Currently, Segmentation of bitewing radiograpy images is a very challenging task. The focus of the study is to segment it into caries, enamel, dentin, pulp, crowns, restoration and root canal treatments. The main method of semantic segmentation of bitewing radiograpy images at this stage is the U-shaped deep convolution neural network, but its accuracy

Hipersensibilidade dentinária: uma abordagem contemporânea [PDF]

open access: yes, 2017
A hipersensibilidade dentinária é caracterizada pela perda de esmalte e de cemento na região cervical dos dentes e consequente exposição dos túbulos dentinários que levam a uma condição dolorosa e de desconforto pelo aparecimento de dor aguda, de curta ...

Using deceased-donor kidneys to initiate chains of living donor kidney paired donations: algorithms and experimentation [PDF]

open access: yesarXiv, 2018
We design a flexible algorithm that exploits deceased donor kidneys to initiate chains of living donor kidney paired donations, combining deceased and living donor allocation mechanisms to improve the quantity and quality of kidney transplants. The advantages of this approach have been measured using retrospective data on the pool of donor/recipient ...

Anti-adversarial Learning: Desensitizing Prompts for Large Language Models [PDF]

open access: yesarXiv
With the widespread use of LLMs, preserving privacy in user prompts has become crucial, as prompts risk exposing privacy and sensitive data to the cloud LLMs. Traditional techniques like homomorphic encryption, secure multi-party computation, and federated learning face challenges due to heavy computational costs and user participation requirements ...
