Effect of cavity preparation design and ceramic type on the stress distribution, strain and fracture resistance of CAD/CAM onlays in molars

J. appl. oral sci; 26 (), 2018
Abstract Objective This study aimed to evaluate the effect of the cavity preparation and ceramic type on the stress distribution, tooth strain, fracture resistance and fracture mode of human molar teeth restored with onlays. Material and Methods Forty-eight molars were divided into four groups (n=12)...

Immunohistochemical and mRNA expression of RANK, RANKL, OPG, TLR2 and MyD88 during apical periodontitis progression in mice

J. appl. oral sci; 26 (), 2018
Abstract Objective To evaluate and correlate, in the same research, the mRNA expression and the staining of RANK, RANKL, OPG, TLR2 and MyD88 by immunohistochemistry in the apical periodontitis (AP) progression in mice. Material and Methods AP was induced in the lower first molars of thirty-five C57BL...

Long-term microwaving of denture base materials: effects on dimensional, color and translucency stability

J. appl. oral sci; 26 (), 2018
Abstract While the combined effect of microwave irradiation with cleansing solutions on denture base materials has been investigated, the effects of only using microwave irradiation and, more importantly, in a long-term basis, was not studied yet. Objective The purpose of this study was to evaluate the...

Dental caries and bacterial load in saliva and dental biofilm of type 1 diabetics on continuous subcutaneous insulin infusion

J. appl. oral sci; 26 (), 2018
Abstract Objectives Since most of the studies evaluates diabetics on multiple daily injections therapy and continuous subcutaneous insulin infusion may help gain better metabolic control and prevent complications, the objective of this study was to evaluate the prevalence of dental caries, the unstimul...

Myofascial trigger points in patients with temporomandibular joint disc displacement with reduction: a cross-sectional study

J. appl. oral sci; 26 (), 2018
Abstract Objective The objective of this retrospective study was to evaluate the impact of myofascial trigger points (MTrPs) in patients with articular disc displacement with reduction (DDWR) and to identify which clinical variables are associated with the concomitant presence of DDWR and MTrPs. Mater...

IFN-γR2 is strongly expressed on endothelial cells of gingival tissues from patients with chronic periodontitis

J. appl. oral sci; 26 (), 2018
Abstract Chronic periodontitis (CP) is characterized by gingival inflammation and bone destruction. It has been reported that interferon-gamma (IFN-γ) levels are high in CP patients; however, the IFN-γ receptor (IFN-γR) has not been studied in gingival tissue from these patients. Objectiv...

Alterations in the stomatognathic system due to amyotrophic lateral sclerosis

J. appl. oral sci; 26 (), 2018
Abstract Objectives: To compare the molar bite force, electromyographic activity, chewing efficiency and thickness of the masseter and temporalis muscles in individuals with amyotrophic lateral sclerosis (ALS) and healthy individuals. Material and Methods: Thirty individuals enrolled in the study were ...

Successful and failed mini-implants: microbiological evaluation and quantification of bacterial endotoxin

J. appl. oral sci; 26 (), 2018
Abstract Objectives Using two groups of mini-implants (successful and failed) the objectives of this in vivo study were: to evaluate the microbial contamination by the checkerboard DNA-DNA hybridization technique and to quantify the bacterial endotoxin by the limulus amebocyte lysate assay. Material a...

Alveolar bone healing in rats: micro-CT, immunohistochemical and molecular analysis

J. appl. oral sci; 26 (), 2018
Abstract Alveolar bone healing after upper incisor extraction in rats is a classical model of preclinical studies. The underlying morphometric, cellular and molecular mechanism, however, remains imprecise in a unique study. Objectives The aim of this study was therefore to characterize the alveolar bon...

Pro-inflammatory and anti-inflammatory cytokine expression in post-treatment apical periodontitis

J. appl. oral sci; 26 (), 2018
Abstract Objective: This study evaluated the expression of pro-inflammatory (IL-1β, IL-6, IFN-γ and TNF-α) and anti-inflammatory (IL-4 and TGF-β) cytokines in apical periodontitis lesions. Correlations between these cytokines and clinical and cone-beam computed tomographic (CBCT) dat...
