The relation between salivary flow rate and salivary constituents suggests that this variation might have a secondary effect on the measures of inorganic ions and buffering capacity. A fluctuation independent of salivary flow rate ... http://dentistrywatch.com/intra-individual-variation-repeated-measures/ There are no comprehensive data on the expected range of measurements for the spacing of short-period lines in ground sections of human dentine, or for that of other animals, at precise locations within the teeth. Kawasaki et al. (1980)found that concentric calcospheritic lines were 1.7 to 2.0 ?m apart in demineralized ... http://dentistrywatch.com/short-period-lines-in-human-dentine/ Oral candidosis is a common opportunistic infection in elderly denture wearers. For instance, 60% of denture wearers over the age of 60 years in Denmark suffer from Candida-associated denture stomatitis. Although these superficial infections are the most prevalent form of the disease, systemic candidal infections are increasingly seen particularly in ... http://dentistrywatch.com/antifungal-agents-dissolved-in-distilled-water/ The periodontal ligament is a dense connective tissue between the root cementum and the alveolar bone that anchors the tooth and maintains the structural integrity of these mineralized tissues. Fibroblasts in the periodontal ligament, the major cell type, are regarded as multipotential, or form a heterogeneous population that can differentiate ... http://dentistrywatch.com/periodontal-ligament-and-mechanical-stress/ Host–tumor interactions lead to a non-specific inflammatory response mediated in part by the chronic production and release of pro-inflammatory cytokines, including IFN-?, interleukins, and tumor necrosis factor. Cytokines are critical for tumor regression. IFN-? is a cofactor in the activation of macrophages, which kill tumor cells, and also enhances cytotoxicity ... http://dentistrywatch.com/cell-line-of-arachidonic-acid/ Elephants are characterized by a highly pneumatic skull with a premaxilla that descends vertically, bearing the roots of the paired tusks, which represent enormously enlarged maxillary incisors. The growth of the tusk is continuous throughout life and its size at any age is dependent on the sex of the animal, ... http://dentistrywatch.com/cementum%e2%80%93ivory-junction-dark-bands-of-the-tusk/ ?-Adrenergic stimulation of the rat parotid gland induces exocytotic amylase secretion from the acinar cells through a cAMP-mediated pathway involving cAMP-dependent protein kinase. During a search of endogenous protein substrates for the kinase, we observed that ?-adrenergic stimulation induces not only phosphorylation of several endogenous proteins but also dephosphorylation of ... http://dentistrywatch.com/2-mercaptoethanol-amino-acid-derived-from-proteins/ The flow of blood through the pulp of mandibular canines in cats and dogs is reduced when the inferior alveolar nerve supplying these teeth is stimulated electrically through bipolar electrodes. This diminution in blood flow following electrical stimulation is inhibited in the presence of the -receptor antagonist phentolamine, which implies ... http://dentistrywatch.com/dental-pulp-sympathetic-nerves-in-human/ Dental calculus or tartar used to be regarded as the most common cause of periodontal disease but it is now recognized that it is probably of secondary importance in the development and progression of the disease and that bacterial irritants in dental plaque are more directly implicated. Calculus may be ... http://dentistrywatch.com/calculus-deposition-of-periodontal-disease-of-teeth/
