The effect of silver nanoparticles on composite shear bond strength to dentin with different adhesion protocols

J. appl. oral sci; 25 (4), 2017
Abstract In Dentistry, restorative materials and oral bacteria are believed to be responsible for restoration failure. To make long-lasting restorations, antibacterial agents should be made. Inorganic nanoparticles and their nano composites are applied as good antibacterial agents. Objective The purpos...

Mechanical properties, water sorption characteristics, and compound release of grape seed extract-incorporated resins

J. appl. oral sci; 25 (4), 2017
Abstract Objective This study evaluated the effect of grape seed extract (GSE) incorporation on the mechanical properties, water sorption, solubility, and GSE release from the experimental adhesive resins. Material and Methods An experimental comonomer mixture, consisting of 40% Bis-GMA, 30% Bis MP, ...

Two-point discrimination values vary depending on test site, sex and test modality in the orofacial region: a preliminary study

J. appl. oral sci; 25 (4), 2017
Abstract The two-point discrimination (TPD) test is one of the most commonly used neurosensory tests to assess mechanoperception in the clinical settings. While there have been numerous studies of functional sensibility of the hand using TPD test, there have been relatively not enough reports on TPD in t...

Effect of photodynamic therapy and non-thermal plasma on root canal filling: analysis of adhesion and sealer penetration

J. appl. oral sci; 25 (4), 2017
Abstract Objective The aim of this study was to evaluate the effect of photodynamic therapy (PDT) and non-thermal plasma (NTP) on adhesion and sealer penetration in root canals. Material and Methods Sixty single-rooted premolars were used. The teeth were prepared using a crown-down technique. NaOCl a...

Bacterial endotoxin adhesion to different types of orthodontic adhesives

J. appl. oral sci; 25 (4), 2017
Abstract Bacterial endotoxin (LPS) adhesion to orthodontic brackets is a known contributing factor to inflammation of the adjacent gingival tissues. Objective The aim of this study was to assess whether LPS adheres to orthodontic adhesive systems, comparing two commercial brands. Material and Methods ...

Treatment of experimental periodontal disease by laser therapy in simvastatin-modified rats

J. appl. oral sci; 25 (4), 2017
Abstract Low intensity laser can be used as a promising alternative in the treatment of periodontal disease. Objective The aim of this study was to evaluate low-level laser therapy (LLLT) as an adjuvant treatment for scaling and root planing (SRP) for the treatment of induced periodontitis in simvastat...

Does laser diode irradiation improve the degree of conversion of simplified dentin bonding systems?

J. appl. oral sci; 25 (4), 2017
Abstract Simplified dentin-bonding systems are clinically employed for most adhesive procedures, and they are prone to hydrolytic degradation. Objective This study aimed to investigate the effect of laser diode irradiation on the degree of conversion (DC), water sorption (WS), and water solubility (WSB...

ABSTRACT BACKGROUND: Due to several factors, such as gastrointestinal's diseases and difficulty in feeding, children with Spastic Quadriplegic Cerebral Palsy tend to present nutritional deficits. OBJECTIVE: To assess the nutritional status of pediatric patients with Spastic Quadriplegic Cerebral Palsy ...

Cranio-vertebral transition assessment by magnetic resonance imaging in a sample of a northeast Brazilian population

Arq. neuropsiquiatr; 75 (7), 2017
ABSTRACT Platybasia and basilar invagination are important alterations of the cranial-vertebral transition. Neuroimaging-based platybasia parameters include the Welcker basal angle, distance between the apex of the odontoid and Chamberlain's line, and the clivus-canal angle. This study aimed to measure a...

Referencias argentinas para la evaluación de proporciones corporales desde el nacimiento hasta los 17 años

Arch. argent. pediatr; 115 (3), 2017
Introducción. La alteración de las proporciones corporales puede ser indicativa de enfermedad esquelética, por lo cual su detección resulta de gran utilidad clínica. Objetivos. Estimar los centilos de los índices perímetro cefálico/estatura (PC/E) y estatura sentada/estatura (ES/E), y evaluar su ...
