Bisphosphonate-associated osteonecrosis of the jaws (BP-ONJ) is a side effect primarily in patients receiving highly potent nitrogen-containing bisphosphonates. The exact etiopathology is unknown. In addition to reduced bone remodeling, there may also be an impact on soft tissues. The impact of nitrogen- (ibandronate, pamidronate, zoledronate) and ...

Objective: Our objective was to verify whether prenatal maternal periodontitis is a risk factor for the development of central nervous system disorders in rats. Methods: Periodontitis was induced by placing a ligature around the upper and lower first molars in 9 female Wistar rats (experimental group); 9 rats were left unligated (control group). Th...

ObjectivePeriodontitis involves periodontal tissue destruction and is associated with chronic inflammation and ageing. Periodontitis has recently been recognised as a risk factor for Alzheimer's disease (AD). We showed upregulation of molecules in the AD pathway including amyloid beta (A4) precursor protein (APP), a key gene in AD, interleukin-1 be...

BackgroundWe reported previously that hypoxia inducible factor (HIF)-1α was not degraded under normoxic condition with transforming growth factor (TGF)-β1 stimulation in human periodontal ligament (PDL) cells; however, the role of HIF-1α has been unclear. Recently, HIF-1α, working together with TGF-β1, has been reported to promote extracellular mat...

ObjectiveNasal obstruction during growth changes craniofacial morphology and function. However, the etiological mechanisms of these changes are unknown. The aim of the present study was to investigate the effects of nasal obstruction during growth on the maturation of the jaw-opening reflex (JOR) using an electrophysiological technique. We focused ...

ObjectiveOur aim was to study the effect of high temperature (39°C) corresponding to fever on the development of enamel in cultured mouse molars. DesignFor morphological studies mandibular molar blocks from E18 mice were cultured for 11 days. After three days at 37°C the teeth were exposed to 39°C for three or five days and returned to 37°C. At the...

BackgroundOral administration of probiotics is known to modulate cytokines profile not only locally, but also systemically. Four strains of Lactobacillus salivarius, LDR0723, BNL1059, RGS1746 and CRL1528, were evaluated for their ability to modulate release of pro- and anti-inflammatory cytokines.FindingsStrains were assessed for effects on product...

ObjectiveOral lichen planus (OLP) is a disease of the oral mucosa of unknown cause producing lesions with an intense band-like inflammatory infiltrate of T cells to the subepithelium and keratinocyte cell death. We performed gene expression analysis of the oral epithelium of lesions in subjects with OLP and its sister disease, oral lichenoid reacti...

ObjectiveAldehydes and reactive nitrogen species (RNS) are important chemically active agents in cigarette smoke (CS). Salivary lactate dehydrogenase (LDH) originates predominantly from oral epithelium and was identified as an oral state marker. Its activity in saliva decreases after CS exposure. The aims of the current study were to identify the s...

ObjectiveHuman pulpal blood flow (PBF) signals as measured by laser Doppler flowmeter (LDF) decrease with age. Although this decrease is considered to be due in part to slow blood flow, information regarding this velocity in humans has been lacking. The aims of the present study were to estimate the blood flow velocity in human dental pulp and to e...
