Fluid and ion secretion from the submandibular gland (SMG) is mainly regulated by parasympathetic nerves. This study evaluated the effect of parasympathectomy on salivary secretion from normal and irradiated rat SMGs from 1 to 24 wk after denervation. Although stimulated salivary secretion was significantly lower in denervated SMGs compared with contralateral self-controls, the resting salivary flow rates were markedly higher in the denervated SMGs at 1, 12, and 24 wk after denervation. The levels of muscarinic acetylcholine M1 and M3 receptors, as well as of aquaporin 5, were up-regulated...

The objective of this study was to develop a viable and reliable technique of delivering viral vectors to rat trigeminal ganglia. Adult Sprague-Dawley rats (200-300 g) were used, and lentiviral vectors containing enhanced green fluorescence protein and calcitonin gene-related peptide short hairpin RNA (shRNA) were generated. Following general anesthesia, viral vectors were delivered to rat trigeminal ganglia using the technique described in this study. Both X-ray and micro-computed tomography (micro-CT) were employed to verify the position of the needles when injecting the vectors...

The purpose of this study was to examine the effect of mold diameter on depth of cure of a resin-based composite material for varying amounts of irradiation. A resin-based composite was light-cured for 10-80 s in stainless-steel molds of either 6 mm or 4 mm in diameter and then dark-stored for 24 h. Specimens were then scraped back and the length of the cured specimens was measured to provide depth of cure (DSB ). Radiant exposure to each of the mold diameters was determined by measuring the power. The DSB values using the 4-mm molds were lower than those of the 6-mm molds...

While the time trends in oral health are favourable, differences still persist in dental status and in prosthetic dental restorations (PDR) between population subgroups. This study aimed to identify changes in oral health in Switzerland over two decades and to describe their relationship to sociodemographic factors in 2012. Swiss Health Surveys were conducted in 1992, 2002, and 2012. The mean number of missing teeth and the prevalence of PDR were calculated at each time point. Logistic regression analysis was performed to assess associations between the prevalence of PDR and sociodemographic factors...

Bradykinin is an important peptide modulator that affects the function of neurons and immune cells. However, there is no evidence of the bradykinin receptors and their functions in human salivary glands. Here we have identified and characterized bradykinin receptors on human submandibular gland cells. Both bradykinin B1 and B2 receptors are expressed on human submandibular gland cells, A253 cells, and HSG cells. Bradykinin increased the intracellular Ca(2+) concentration ([Ca(2+) ]i ) in a concentration-dependent manner...

The aims of this study were to determine whether: (i) the jaw motor system develops a new pattern of jaw movement and/or jaw-muscle activity after resolution of an acute episode of jaw-muscle pain; and (ii) if jaw-muscle activity and jaw-movement features change progressively with repetition of a chewing sequence. Jaw movement and jaw muscle (masseter, anterior temporalis, and digastric) activity were recorded during free and rate-standardized chewing in eight asymptomatic participants (pain infusion group), before and at three time blocks up to 45 min after a single 0...

The biomimetic remineralization of apatite-depleted dentin is a potential method for enhancing the durability of resin-dentin bonding. To advance this strategy from its initial proof-of-concept design, we sought to investigate the characteristics of polyacrylic acid (PAA) adsorption to desorption from type I collagen and to test the mineralization ability of PAA-bound collagen. Portland cement and β-tricalcium phosphate (β-TCP) were homogenized with a hydrophilic resin blend to produce experimental resins...

Immunosuppressive agents have been recognized as a factor affecting bone metabolism. The aim of the present study was to evaluate the influence of FK-506 administration on the healing of bone around titanium implants. Thirty-two male mice were randomly allocated to two groups: the FK-506 group (n = 16 mice), which received subcutaneous administration of FK-506 (1 mg kg(-1) d(-1) ); and the control group (n = 16 mice), which received saline solution by the same route of administration. After 2 wk, one titanium implant with sandblasted/acid-etched surface was placed in the femur...

This study evaluated the stability of resin-dentin interfaces treated with glutaraldehyde-containing agents, and assessed collagen degradation in dentin matrices treated with Gluma. Microtensile bond strength (μTBS) was evaluated 24 h and 6 months after treatment with three desensitizers (Gluma Desensitizer, Gluma Desensitizer Power Gel, and MicroPrime G) and two etch-and-rinse adhesives (Comfort Bond & Desensitizer and iBond TE). Demineralized beams of human dentin were treated with water or Gluma, and the degradation of collagen in these beams was assessed by quantification of the dry mass loss and of the amount of hydroxyproline released from hydrolyzed specimens after 1 or 4 wk...

Latent-transforming growth factor beta-binding protein 3 (LTBP-3) is important for craniofacial morphogenesis and hard tissue mineralization, as it is essential for activation of transforming growth factor-β (TGF-β). To investigate the role of LTBP-3 in tooth formation we performed micro-computed tomography (micro-CT), histology, and scanning electron microscopy analyses of adult Ltbp3-/- mice. The Ltbp3-/- mutants presented with unique craniofacial malformations and reductions in enamel formation that began at the matrix formation stage...

The aim of this study was to elucidate the relationship between the gustatory function and average number of taste buds per fungiform papilla (FP) in humans. Systemically healthy volunteers (n = 211), pre-operative patients with chronic otitis media (n = 79), and postoperative patients, with or without a chorda tympani nerve (CTN) severed during middle ear surgery (n = 63), were included. Confocal laser scanning microscopy was employed to observe fungiform taste buds because it allows many FP to be observed non-invasively in a short period of time...

Children with untreated coeliac disease (CD) may develop enamel defects. Moreover, children with untreated CD have increased serum levels of gliadin reactive IgG, which may cross-react to amelogenin. The aim of this study was to investigate reactivity of anti-gliadin IgA and IgG to amelogenin in children with untreated CD. Blood samples from patients with CD (n = 75) and from disease controls (n = 24) were analysed for IgA and IgG reactivities to amelogenin (Emdogain) and to gliadin by ELISA. Whereas children with CD had statistically significantly higher serum levels of anti-amelogenin IgA, only those with the most severe CD (Marsh 3c) had significantly higher anti-amelogenin IgG immune reactivity than the disease controls...

Normal jaw opening-closing involves simultaneous jaw and head-neck movements. We previously showed that, in men, integrated jaw-neck movements during jaw function are altered by induced masseter muscle pain. The aim of this study was to investigate possible sex-related differences in integrated jaw-neck movements following experimental masseter muscle pain. We evaluated head-neck and jaw movements in 22 healthy women and 16 healthy men in a jaw opening-closing task. The participants performed one control trial and one trial with masseter muscle pain induced by injection of hypertonic saline...

Patients with cardiac implantable electrical devices should take special precautions when exposed to electromagnetic fields. Proximity to equipment used in clinical dentistry may cause interference. This study evaluated in vitro the risks associated with different types/makes of cardiac devices and types of dental equipment. Six electronic dental tools were tested on three implantable cardioverter defibrillators and three pacemakers made by different manufacturers. Overall, the risk of interference with the pacemakers was 37% lower than with the implantable cardioverter defibrillators...
