Enamel is continuously affected by the process of wear Although

Enamel is continuously affected by the process of wear. Although the tooth wear is recognized the physiological and irreversible this website phenomenon, there are individuals in whom this process of wear

occurs dramatically faster and, if not treated, may lead to the complete destruction of stomatognathic system [22]. The cause of this acceleration of tooth wear is multifactorial as it is generally a combination of abrasion, attrition, and erosion. [23]. Thus, the processes of local demineralization and remineralization reflecting the erosion-attrition or erosion-abrasion play the key role in the clinical picture of wear [24–27]. As underlying mechanisms seem unclear in this condition, it is worth evaluating associations between tooth wear, skeletal status, and potential pathogenic pathways, focused on enamel composition. The effects of microelements such as zinc and copper on tooth demineralization and remineralization

have been previously described [28, 29]. Zinc has been reported to reduce enamel solubility [29, 30]. It has been also suggested that zinc is incorporated into enamel during remineralization in situ despite a moderate level of an increase in zinc concentration [31]. Brookes et al. have further demonstrated that copper has a direct protective effect on the dissolution of enamel in acidic environment, being a major driving force for both caries and erosion [32]. By contrast, Koulourides VX-770 order observed an inhibition of enamel remineralization by Cu, presumably due to ionic interaction with the active enamel surface following demineralization [33]. Beyond an evident significance of calcium-phosphate in bone turnover, the role of micronutrients and elements, i.e., iron, magnesium, manganese, selenium, zinc, and copper is also well known in bone metabolism [34–38]. Trace elements, in particular zinc and copper, are actively participating in enzymatic systems responsible for bone matrix turnover [39]. Zinc is a constituent of approximately PD184352 (CI-1040) 300 enzymes, including

those essential for bone metabolism (bone alkaline phosphate) [40]. Copper is another trace element involved in bone metabolism as a cofactor of lysyl oxidase, one of the principal enzymes participating in collagen cross-linking. Animal studies suggest that Cu deficiency is associated with reduced bone strength and deterioration of bone quality leading to osteoporotic lesions [41]. Considering that enamel represents similar features, qualities, and mineralized components to bone tissues, we aimed to investigate possible associations between enamel mineral composition and BMD in adult patients with tooth wear. We hypothesized that both systemic bone loss (lower BMD) and excessive abrasion of dental enamel coincided in www.selleckchem.com/products/Fedratinib-SAR302503-TG101348.html subjects with severe tooth wear. Patients and methods Participants In this cross-sectional observational study, 50 participants (16 women, 34 men) aged 47.5 ± 5 years with advanced tooth wear were included.
