In vitro antimicrobial efficiency of a mouthwash containing triclosan/gantrez and sodium bicarbonate
(Brazilian Oral Research, 2007-12-31) [Artigo]
Several antiseptic substances have been used as adjuncts to routine mechanical procedures of oral hygiene, based on their antimicrobial effects. The objective of this study was to assess in vitro the antimicrobial efficiency ...
Quantitative cell-cycle protein expression in oral cancer assessed by computer-assisted system
(Histology and Histopathology, 2006-07-01) [Artigo]
The knowledge of cell-cycle control has shown that the capacity of malignant growth is acquired by the stepwise accumulation of defects in specific genes regulating cell growth. Histologic diagnosis might be improved by a ...
Effect of post-polymerization heat treatments on the cytotoxicity of two denture base acrylic resins
(Journal of Applied Oral Science, 2006-08-31) [Artigo]
Introduction: Most denture base acrylic resins have polymethylmethacrylate in their composition. Several authors have discussed the polymerization process involved in converting monomer into polymer because adequate ...
Mechanical and biological characterization of resin-modified glass-ionomer cement containing doxycycline hyclate
(Archives of Oral Biology, 2012-02-01) [Artigo]
Objectives: To characterize the mechanical and biological properties of a resin-modified glass ionomer cement (RMGIC) containing doxycycline'hyclate.Methods: The antibacterial effect of RMGIC containing 1.5, 3.0 and 4.5% ...
p16INK4A immunohistochemical overexpression in premalignant and malignant oral lesions infected with human papillomavirus
(Journal of Histochemistry and Cytochemistry, 2003-10-01) [Artigo]
Human papillomavirus (HPV) is believed to promote the oncogenic process, and the correlation between viral oncoproteins and dysfunction of p16 INK4A tumor suppressor protein in oral lesions is controversial. To test the ...
Cytotoxicity of denture base resins: Effect of water bath and microwave postpolymerization heat treatments
(International Journal of Prosthodontics, 2004-05-01) [Artigo]
Purpose: This study compared the effect of two postpolymerization heat treatments on the cytotoxicity of three denture base resins on L929 cells using 3H-thymidine incorporation and MTT assays. Materials and Methods: Sample ...
Genetic polymorphism of Streptococcus mutans strains associated with incomplete caries removal
(Brazilian Journal of Oral Sciences, 2009-12-01) [Artigo]
Aim: Despite the antibacterial properties of dental materials, the survival of residual bacteria under restorations has been demonstrated after incomplete caries removal. The aim of this study was to evaluate the genetic ...
Lack of correlation between periodontitis and renal dysfunction in systemically healthy patients
(European Journal of Dentistry, 2011-01-01) [Artigo]
Objectives: The aim of this study was to assess a suggested association between periodontitis and renal insufficiency by assaying kidney disease markers. Methods: Variables used to diagnose periodontitis were: (i) probing ...
The influence of short-term diabetes mellitus and insulin therapy on alveolar bone loss in rats
(Journal of Periodontal Research, 2004-06-01) [Artigo]
Background: It is well known that the multiple direct and indirect consequences of hyperglycemia in diabetic individuals have been linked to a number of abnormal host effector mechanisms that could lead to an increased ...
On a possible dual role for the lateral septal area 5-HT1A receptor system in the regulation of water intake and urinary excretion
(Behavioural Brain Research, 2010-12-20) [Artigo]
The 5-hydroxytryptamine (5-HT)(1A) receptor system plays a prominent role in a variety of physiological functions and behavior and regulation of this responsiveness of the receptor system has been implicated in the central ...
