Precancerous lesions of the mouth. 口腔癌前病变。

{"title":"Precancerous lesions of the mouth.","authors":"L M Abbey","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Leukoplakia is the only important precancerous lesion of the mouth. The epidemiology of oral leukoplakia has been well established in white adults in the United States. There is a hole in the epidemiologic literature, however, on leukoplakia in American minority populations. Recent literature has begun to address the issue of the pathophysiology of leukoplakia, its causes and treatment, and predicting its malignant transformation. Computerized image analysis, retinoid compounds, beta-carotene, and laser surgery are contributing to advances in these lines of research. Though leukoplakia is often seen in patients who use smokeless tobacco products, it is usually benign and reversible if use of the tobacco product is discontinued. The direction of current research in leukoplakia studies eventually should lead to an understanding of the nature and cure of this ubiquitous lesion.</p>","PeriodicalId":10853,"journal":{"name":"Current opinion in dentistry","volume":"1 6","pages":"773-6"},"PeriodicalIF":0.0,"publicationDate":"1991-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12969439","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}

Cell adhesion molecules in oral mucosa. 口腔黏膜细胞黏附分子。
Current opinion in dentistry Pub Date : 1991-12-01

{"title":"Cell adhesion molecules in oral mucosa.","authors":"E Dabelsteen","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>The way in which cells communicate with each other is fundamentally important for developing and maintaining normal tissue structure and function. In order to get a better understanding of cell adhesion, researchers have long been trying to identify and characterize chemical structures at the cell surface that might participate in, or mediate, cell-cell and cell-matrix adhesion. During the last decade, this has led to the identification of a number of cell-surface adhesion proteins and their ligands, which may be either proteins or carbohydrates. The LEC cell-adhesion molecule family is a group of cell-adhesion molecules with a lectinlike domain. They bind to carbohydrate structures, some of which have been identified on dendritic cells in oral epithelium. LEC cell-adhesion molecules are found on endothelial cells during inflammation and may, in such situations, be involved in the recruiting of dendritic and other inflammatory cells, thereby playing a role in the regulation of inflammatory reactions in the oral mucosa. The integrin family is another group of cell-surface adhesion molecules recently identified in oral mucosa that participate in cell-matrix and cell-cell adhesion in many important processes including wound healing, immunodefense mechanisms, and oncogenic transformation. Knowledge of the distribution of cell-adhesion molecules and their ligands and of the mechanism that controls their expression is, therefore, of great importance in understanding of the development of disease in the oral mucosa.</p>","PeriodicalId":10853,"journal":{"name":"Current opinion in dentistry","volume":"1 6","pages":"802-8"},"PeriodicalIF":0.0,"publicationDate":"1991-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12969443","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}

Molecular mechanisms in dental hard tissue mineralization. 牙硬组织矿化的分子机制。

{"title":"Molecular mechanisms in dental hard tissue mineralization.","authors":"H Limeback","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>During the period covered by this issue, over 500 papers were published in the area of biology of dental hard tissues. This review is limited to publications that focus on the organic matrix components believed to be important in the formation of dentin, cementum, and enamel. The advances made in this area for the collagen-based dental hard tissues (dentin and cementum) have been primarily in the isolation and partial characterization of the noncollagenous proteins such as proteoglycans, phosphoproteins, and proteins normally found in bone. These proteins are being studied because of their potential role for directing hydroxyapatite nucleation or crystal growth. The progress made in the enamel field has been primarily in the area of molecular biology. Enamel is quite different physically from dentin and cementum because it is formed from a noncollagenous matrix (mostly amelogenin), which is almost completely removed and replaced with hydroxyapatite. Serum proteins have now been found in all dental hard tissues including enamel. Opinions on the clinical significance of these advances are provided.</p>","PeriodicalId":10853,"journal":{"name":"Current opinion in dentistry","volume":"1 6","pages":"826-35"},"PeriodicalIF":0.0,"publicationDate":"1991-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12832205","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}

{"title":"Bone and biologically compatible materials in dentistry.","authors":"I Binderman","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>This review focuses on compatible materials that are either implanted in bone tissue to serve as prosthetic devices or used as bone substitutes. It attempts to evaluate the significance of studies of combined osteoconductive materials with osteoinductive factors, like demineralized bone or its purified components, and osteogenic cells. It is important to note that the term osseointegration, which is still widely used by clinicians to indicate the bioactivity of implants in bone healing, is not substantiated by any controlled basic study.
