one of the main factors that affect the success of the cast crown is the accuracy of the internal and marginal fit, a well-fitting crown reduces the chance for recurrent caries and periodontal disease, whereas the space between a poorly-fitting crown and tooth preparation enables accumulation of bacterial plaque, the use of paint- on die spacing technique to produce the cement gap and subsequently to improve the seating of the cast crowns has become quite popular in the recent years. The purpose of the study is to compare the marginal gap and the internal fit produced by two paint-on die spacing materials (Manicure and paint on die spacer ). Twenty four identical stone dies were made, 12 were coated with paint- on die spacer material, and 12 were coated with nail varnish material, the dies coated with die spacer were divided into three groups (DA,DB,DC), and the dies coated with nail varnish were also divided into three groups (VA,VB,VC), groups DA and VA were coated with one layer, DB and VB were coated with two layers, DC and VC were coated with three layers, for both groups wax patterns were made and casted using the lost waxing technique and all steps were standardized, impression replicas of the casted crowns were made and sectioned by means of the impression replica technique, measurements were taken using Scanning Electron Microscope, from 4 points (marginal gap, mid-axial, axio-occlusal and mid-occlusal). There was no statistical significant difference in accuracy between crowns fabricated on die spacer coated dies and crowns fabricated on nail varnish coated dies. with the crowns fabricated on die spacer coated dies being slightly more accurate.

More Abstract This work shares Libyan experiences with medical education accreditation, as well as the challenges that the system faced in meeting the criteria of the World Federation of Medical Education (WFME). WFME, which was founded in 1972, is an international organization concerned with the education and training of medical doctors. WFME was initiated on the initiative of the WHO and the World Medical Association (WMA) with the goal of reviewing bodies that accredit basic medical education. The worldwide task force on accreditation in medical education was founded in 2004 by WHO and the WFME. In the same year, 26 members from 23 countries representing all six WHO–WFME regions assembled to discuss how WHO and WFME could assist in the establishment of long-term accrediting systems to ensure high-quality medical education. By 2024, all candidates must obtain a graduation certificate from a program certified by an entity that meets WFME or other international requirements for an accrediting system, according to the Educational Commission for Foreign Medical Graduates. Thereafter, accreditation for all health training programs by 2020 was indorsed as part of the WHO’s Worldwide Strategy on human resources for health: workforce 2030 and was recommended by the WMA. In response to these regulations, the NCQAA has started to prepare “the National Standards Manual for Basic Medical Education” and further connect with all Libyan medical faculties to comply with these criteria, while linking with the WFME. This is based on the WHO endorsement that all countries to apply accreditation mechanisms for health training institutions by 2020. Now it is a time to call for a rigorous auditing system in addition to assessment mechanisms in order to warrant ongoing quality control, and the quality control agency should be self-governing of external encouragement and have only an academic agenda. Finally, all medical schools that have decided to be recognized by the WFME, must have strengthened their ability to face challenges and start adapting these regulations and standards. The construction of networks, alliances, and associations between Libyan medical faculties are encouraged as an efficient approach for implementing and obtaining this accreditation.

طالما أن الفرد والمجتمع متلازمان ولا ينفصلان، فإنه يجب تنظيم العلاقة بين سلطة الدولة وحريات الأفراد وبما أن ،في المجتمع الدستور يمثل وسيلة الحكم الديمقراطي في المجتمعات المتقدمة، فعليه تقع مهمة تنظيم هذه العلاقة تحيل كونه يس تصور مجتمع بشري بدون تشريع، فالرابطة الاجتماعية هي رابطة قانونية قبل كل شيء وحيث يكون المجتمع يكون القانون. وفي الواقع، لا تكون حماية ممارسة الحريات العامة دائما وفي كل مكان بنفس الطريقة، حتى داخل الدولة كما أن ال ،الواحدة حلول تختلف تبعا للحريات المعنية، أي تبعا للنشاط الإنساني المعني، وأنماط تنظيمها لا يقع دائما على ذات المستوى ، وإنما يتغير تبعا للحالات العادية التي يكون فيها المجتمع والظروف الاستثنائية التي تمر .بها البلاد لذلك فإن أساليب تنظيم الحرية ليست واحدة فقد تكون عن طريق الدستور أو القانون كما قد تكون عن طريق القرارات الإدارية التنظيمية .
