PURPOSE To compare the genoprotective and radioprotective effect of carnosol (COL) against damage induced by ionizing radiation with similar effects produced by different antioxidant compounds. METHODS The genoprotective effect was studied by means of the micronucleus test for antimutagenic activity in which the reduction in the frequency of micronuclei(More)
OBJECTIVES To determine if canting of the occlusal plane influences esthetic evaluation of the smile among orthodontists, dentists and laypersons. STUDY DESIGN A frontal photo of a smile with 0 occlusal plane canting in relation to the bipupillary plane was modified using Adobe Photoshop C3 (Adobe Systems Inc, San José, California) to generate two images(More)
INTRODUCTION Zoledronic acid (Z) is a bisphosphonate used in hypercalcaemia-related cancer, in complications for bone metastasis and in postmenopausal osteoporosis and it has been related to osteoradionecrosis, especially when associated with radiation to the head and neck structures. OBJECTIVES To determine the radiosensitization capacity of zoledronic(More)
BACKGROUND Rosmarinic acid is an ester of caffeic acid with interesting biological activities including antioxidant effects and scavenging of oxygen-free radicals. AIM To determine the potentially paradoxical effect of rosmarinic acid, typically being radioprotective when applied to non-tumorous cells, yet conversely displaying a sensitizing action when(More)
OBJECTIVE To determine the in vitro toxicity of different concentrations of sevoflurane in cells exposed to X-ray. METHODS The genotoxic effects of sevofluorane were studied by means of the micronucleus test in cytokinesis-blocked cells of irradiated human lymphocytes. Subsequently, its cytotoxic effects on PNT2 (normal prostate) cells was determined(More)
BACKGROUND Zoledronic acid is used in the treatment of cancer-related diseases, although its use has been associated with avascular osteonecrosis. AIMS To determine the possible protective effect of a range of antioxidant substances against the inhibition of human prostate epithelial cell growth (PNT2) and transgenic adenocarcinoma mouse prostate tumour(More)
BACKGROUND To determine the toxicity of aqueous dilutions of a universal self-priming dental adhesive (DA) and comparing these with those elicited by exposure to ionizing radiation (IR), Zoledronic acid (Z) treatment and the synergic effects of the combined treatment with IR+Z. MATERIAL AND METHODS The genotoxic effect of DA was determined by the increase(More)
BACKGROUND Bisphosphonates are used in cancer-related hypercalcaemia, in complications of bone metastasis and in postmenopausal osteoporosis, and have often been associated with adverse complications. AIM To determine the protective effect of apigenin against growth inhibition of normal epithelial human prostatic (PNT2), transgenic adenocarcinoma of mouse(More)
A total of 34 044 official quality assurance reports in dental radiodiagnostic surgery from 16 regions of Spain, compiled from 2002 to 2014, were studied in order to determine the progress of diagnostic reference levels (DRLs) for obtaining diagnostic images under normal conditions for clinical practice in Spanish dental clinics. A DRL of 2.8 mGy was set in(More)
