Review Of The Literature

Summary: The purpose ofthis article is to present a review of different investigation approaches to evaluate thebiocompatibility of dental materials. A search was conducted among the investigators in this fieldin order to define the test methods applied to evaluate dental materials. The described stages foreach test are found in the literature used to evaluate the biocompatibility of different materialsused in dental practice. At the end of this review it can be concluded that compliance with researchprotocols and results obtained on biocompatibility of these studies provide confidence for the useof various dental materials. Key words: Dental materials. Biocompatiblity. Citotoxicity. Dentalpulp.

This study analyzes international historical trends in the use of different types of materials in dental practice. The author describes the chemical properties of their ingredients and the potential and observed adverse effects in patients and dental technicians resulting from clinical or occupational exposure to various metals like beryllium, used to produce metal alloys. The growing use of various products (resin cements, ionomer cements, aesthetic restorative materials, resins, endodontal cements, and others) based on the compound bisphenol-A, whose chemical structure is similar to that of estrogen. Considering the demographic and contemporary work force characteristics of those involved in dental practice in the Brazil, the study highlights the possible effect of the use of these materials in both male and female patients and all age strata, as well as in health professionals with occupational exposure to products containing bisphenol-A.

During the 20th century, both dental materials and dental technologies for the fabrication of dental prosthesis progressed remarkably. Owing to the increased demand of safety and aesthetics, 3 mol% yttria stabilized tetragonal zirconia polycrystalline has been recently introduced in prosthetic dentistry for the fabrication of crowns and fixed partial dentures, in combination with CAD/CAM technique. This greatly changed the conventional dental laboratory work which is labor-intensive and experience-dependent. This review mainly introduced the state of dental zirconia and the application of CAD/CAM technology in dentistry.

Anecdotal Information

Background: Barefoot running is slowly gaining a dedicated following. Proponents of barefoot running claim many benefits, such as improved performance and reduced injuries, whereas detractors warn of the imminent risks involved. Methods: Multiple publications were reviewed using key words. Results: A review of the literature uncovered many studies that have looked at the barefoot condition and found notable differences in gait and other parameters. These findings, along with much anecdotal information, can lead one to extrapolate that barefoot runners should have fewer injuries, better performance, or both. Several athletic shoe companies have designed running shoes that attempt to mimic the barefoot condition and, thus, garner the purported benefits of barefoot running. Conclusions: Although there is no evidence that either confirms or refutes improved performance and reduced injuries in barefoot runners, many of the claimed disadvantages to barefoot running are not supported by the literature. Nonetheless, it seems that barefoot running may be an acceptable training method for athletes and coaches who understand and can minimize the risks. (J Am Podiatr Med Assoc 101(3): 231–246, 2011)

The Relationship

ABSTRACT Introduction: Hepatocellular carcinoma is one of the most frequent types of malignant tumors in the world. There is growing evidence of the relationship between it development and obesity. The mechanism that links obesity to cancer is still not fully understood; however, it is essential to the understanding the adipose tissue in metabolic changes related to obesity and hepatocellular carcinoma. Objective: To review the influence of serum leptin levels in patients with hepatocelular carcinoma. Method: Systematic review of the literature based on the methodology of the Cochrane Institute. The search for articles was in the database: Science Direct, Scielo, Medline, Lilacs e Pubmed. The key words used were hepatocellular carcinoma, leptin, adipokine. Results: After evaluation of individual studies, were selected seven studies. The results previously studied are still inconsistent and contradictory, and leptin can be effectively involved in the occurrence and development of hepatocellular carcinoma. Conclusion: Therefore, it is necessary to develop prospective, well-designed and conducted focusing on the role and specific mechanisms of this hormone in patients with hepatocellular carcinoma, so that new correlations can be properly supported.
