The responsibility of the education is mainly devoted to the organizations usually the Dental authorities, Universities and Dental National associations. Moreover the Speaker is the central person in charge of.the transmission of the knowledge and the skill. Therefore a proper evaluation is an imperative necessity. Generally the use of questionnaire is utilized in order to ascertain the satisfaction of the Dentists of the Lectures. In this three year survey an attempt to set up Speaker Guidelines was launched.

As factors (a) and (b) are constants, the only variable factor is the drilling technique(c). Since the quality of the bone varies (type D1-4), the clinician would like to have the ability to influence the amount of drilled bone. In addition, the clinician wants absolute accuracy & control in location and direction of the drill--in the minimizing of error and the ability to see it and correct it. These elements can be achieved by a system which includes trephine drills and leading pins. This article suggests a drilling technique developed for the purpose of placing dental implants.

The specific properties achievable with diverse chemical combinations provide for a wide range of implications in many industrial fields. Materials designed for medical use must not only efficiently serve the purpose of their use, but also be biocompatible to the tissues they contact and the body as a whole. Dental composites and their components have been studied intensely to assess their potential local and systemic side effects, to establish biocompatibility, in order to receive the proper conformation allowing their safe clinical use. The purpose of the following paper is to summarize several aspects of research focused on determining cytotoxicity, genotoxicity, carcinogenicity, hypersensitivity, and microbial effects of composite components, in order to ascertain in fact how biocompatible dental composite materials are. Research shows that several chemical components may be released from different types of composites, and are able to cause toxic, allergic, mutagenic and other biological effects. However, because of the small amounts applied and the unique conditions in the oral cavity, the clinical relevance of these findings is questionable. Nevertheless, caution should be taken when using these materials, to avoid possible negative outcomes. Future studies should focus on targeting most toxic components and finding biocompatible alternatives and development of materials with high polymerization efficiency in order to reduce the amount of leachable components.</p>","PeriodicalId":82453,"journal":{"name":"Refu'at ha-peh veha-shinayim (1993)","volume":"32 1","pages":"21-9, 60"},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33028642","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}

It is employed in many different academic disciplines most particularly in the social sciences and humanities, however recently more and more qualitative research is being conducted under the medical sciences including dentistry and orthodontics. This is due to its nature of in-depth investigation, which can provide answers to questions that cannot be satisfactorily answered using quantitative methods alone. The aims of this article are to discuss the characteristics of qualitative research, to review the orthodontic English literature, and to highlight the advantages of qualitative research in orthodontics. The literature review yielded several important conclusions regarding qualitative research in orthodontics: 1. most of the qualitative research done in orthodontics chose to use semi structured in-depth interviews for data collection; 2. qualitative research highlights aspects that are very important, and sometimes crucial to everyday practice and long term treatment; 3. there is a lack of qualitative studies in the field of orthodontics. Taking into account the nature of the orthodontic treatment, which is a prolonged one, demanding of a good orthodontist-patient rapport, and a wide perspective on behalf of the clinician, filling the gap in the discipline through conducting more qualitative studies aimed at understanding the point of view of the patient, as well as that of the clinician, may be beneficial for the improvement of the treatment.</p>","PeriodicalId":82453,"journal":{"name":"Refu'at ha-peh veha-shinayim (1993)","volume":"32 1","pages":"30-6, 61"},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33028643","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}

Regeneration of the lost bone is crucial for the patient rehabilitation of function, phonetics and aesthetics. The surgical techniques for jaw-bone augmentation include: distraction osteogenesis, bone blocks (autologic/allogenic or xenogenic) and guided bone regeneration (GBR). These techniques have low predictability and high morbidity. As an alternative to the classical surgical approaches, in recent years, there have been developments in the field of tissue engineering which integrates the use of different scaffolds, growth factors and stem cells. This method aims to induce bone augmentation of large defects essentially mimicking biological processes that occure during craniofacial development. This article will review recent studies and a future outlook for the use of adult mesenchymal stem cells (MSC) and endothelial progenitor cells (EPC)--in order to induce bone augmentation in cases of severe bone resorption.
