It is likely that fluoride affects the remodelling processes of the skeleton as well as growth related bone formation. During bone remodelling the amount of bone and osteoid tissue is increased by alteration of the balance between resorption and formation. This finding may be accompagnied by impaired mineralization. In studies of fluoride effect on growth related bone formation a number of quantitative histologic alterations have been observed. These include reduction in epiphyseal plate thickness and changes in cellular morphology as well as a retardation of mineralization. The pathogenetic mechanisms behind the observed effects and the variation in tissue response are still unexplained. Fluoride may have a direct cellular effect causing disturbances in cell morphology and metabolism, but the effects may also involve local supracellular mechanisms as well as the general homeostasis of the individual.</p>","PeriodicalId":76577,"journal":{"name":"Tandlaegebladet","volume":"94 18","pages":"761-3"},"PeriodicalIF":0.0,"publicationDate":"1990-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13253402","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The osteosynthesis increase stability in many situations, and may reduce or eliminate the need for post-operative intermaxillary fixation, by which morbidity, hospitalization period and period of sick-leave can be reduced. In orthognathic surgery, the stability of the miniplate osteosynthesis increase the demand for precision during surgery as compared to conventional fixation with wire osteosynthesis and intermaxillary fixation.

ORN is the end stage of tissue injury induced by irradiation. The most prominent etiologic factor of ORN seems to be the effect of radiation on endothelial cells lining the vessels. These cells are, as tumor cells, highly radiosensitive, and radiation leads to a vascular damage resulting in hypoxic, hypovascular and hypocellular tissues. Wound healing in such tissues is impaired since nutritional demands of the wound, including oxygen, cannot be supplied due to the degenerative changes in the blood vessels. The paper furthermore describes the scientific basis for the use of hyperbaric oxygen therapy (HBO) in ORN. HBO increase the vascularity in the tissues injured by radiation, and thus tissue viability and healing capacity is increased reducing the risk for spontaneous or traumainduced ORN. Protocols for the treatment of patients with ORN are presented and prophylactic guidelines are described.</p>","PeriodicalId":76577,"journal":{"name":"Tandlaegebladet","volume":"94 16","pages":"669-73"},"PeriodicalIF":0.0,"publicationDate":"1990-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13283277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
