Resumo Os novos materiais restauradores em desenvolvimento devem evitar danos aos tecidos dentários. Portanto, o objetivo deste estudo foi avaliar a biocompatibilidade de uma marca comercial de cimento de ionômero de vidro convencional (CIV) modificado com microfibras de celulose (CIV+MC) ou nanocrista...

Reference values for selected ophthalmic tests of the blue-and-yellow macaw (Ara ararauna)

Pesqui. vet. bras; 37 (4), 2017
The aim of this study was to establish reference values for selected ophthalmic diagnostic tests in healthy blue-and-yellow macaws. We investigated a total of 35 adult macaws (70 eyes) of undetermined sex and with an average weight of 1 kg, who were living in captivity in the Federal District, Brazil. Te...

Discoloration and force degradation of orthodontic elastomeric ligatures

ABSTRACT OBJECTIVE: The aim of the present study was to evaluate color changes and force degradation of orthodontic elastomeric ligatures in different stretching patterns during a 8-weeks period. METHODS: Two elastomers with the minimum and two with the maximum color changing, and gray elastomers of t...

Six-month bracket failure rate with a flowable composite: A split-mouth randomized controlled trial

ABSTRACT INTRODUCTION: The use of flowable composites as an orthodontic bonding adhesive merits great attention because of their adequate bond strength, ease of clinical handling and reduced number of steps in bonding. OBJECTIVE: The aim of this Randomized Controlled Trial was to comparatively evaluat...

Densitometric response in postmenopausal osteoporosis treated with strontium ranelate or denosumab

Actual. osteol; 13 (1), 2017
Tanto el ranelato de estroncio (RSr) como el denosumab (Dmab) son eficaces en el tratamiento de la osteoporosis (OP) posmenopáusica (PM). El efecto de cada fármaco por separado sobre la densidad mineral ósea (DMO) ha sido estudiado recientemente. Con ambas drogas se observó, al año de tratamiento, u...

Influence of β-tricalcium phosphate of different geometric shape on the morphology of regeneration of experimental defect of compact bone tissue

Actual. osteol; 13 (1), 2017
Purpose: to compare the healing process of a defect of compact bone tissue after the implantation of osteoplastic materials based on β-tricalcium phosphate (“ChronOS™” and “Calc-i-oss®”), which differ by manufacturer, geometrical shape and microscopic structure. Methods: the experiment was pe...

Investigation on the biological effect of fluorine present on the surface of titanium implants: analysis of the reaction fluoride-titanium oxide

Actual. osteol; 13 (1), 2017
The aim of this work was to investigate the state of fluoride at the surface of fluoridemodified titanium implants, and to provide information to support or discard the hypothesis that fluoride ion participates in the osseointegration of implants. Titanium is coated with a 2-10 nm thick layer of stable a...

Osseointegration of titanium implants anodized with and without fluoride in the electrolyte: a study in rats

Actual. osteol; 13 (1), 2017
Based on the hypothesis that fluoride acts as a bone anabolic agent, the aim of this study was to measure in rats the osseointegration of implants (grade II titanium wire, 1 mm diameter, 4 mm long) submitted to anodic oxidation in 2 M phosphoric acid solution (control implants) or b) in 2 M phosphoric ac...
