This study was primarily conducted to investigate the prevalence of imported malaria in a sample of foreign workers (n-1038) in Tripoli during the period from May 2006 to June 2007. A comprehensive review of malaria epidemiology in Libya in the last two decades was also given. All samples were tested serologically using Malaria Rapid Diagnostic test and then examined using blood film technique. Results showed that only 10 samples (1%) were tested positive for both malaria rapid diagnostic test and blood film. Nine of those infected were identified as Plasmodium falciparum and one as Plasmodium vivax. This study confirms that the prevalence of malaria in legal foreign workers is low and the risk of re-introducing or transmitting malaria in the northern areas of the country is remote. It also gives no good reason for including malaria test among those requested for issuing health certificates to foreign workers. The use of malaria Rapid Diagnostic test for malaria detection in this study was proved to be practical and reliable. Although, the situation of imported malaria in Libya imposes no immediate threat to re-emerging of malaria in the country however, continuous surveillance and monitoring particularly to the southern regions and populations have to be taken in a great consideration. An updated new map of malaria vectors distribution in Libya is urgently needed to be able to outline areas of high risk of malaria transmission.

Abstract Back ground: Full coverage porcelain fused to metal crowns (PFM) is commonly recommended for restoration of extensively damaged teeth. Ability of the dentist to adequately prepare teeth is necessary to achieve a proper success and longevity of these restoration. Aims: This study aimed to determine the degree of axial taper and total occlusal convergence angles (TOC) for Porcelain Fused To Metal crowns (PFM) prepared with clinically practiced values, that carried out by dental practitioners in Tripoli center, Libya. Materials and Methods: It was a descriptive, cross-sectional study design and held at Alzendah private dental laboratory, Tripoli Libya. A convenience sample (40) models of Porcelain Fused To Metal Crowns (PFM) preparations carried out by private dental practitioners were scanned by employing a 3D model scanner (Ceramill Map300, Amanngirrbach, Austria). Evaluation of the total occlusal convergence (TOC), bucco-lingual and mesio-distal convergence angles of each abutment tooth was proceeded using B&B dental software (Guide system, B&B, Italy). The degree of taper was measured on the axial walls of each crown preparation and the bucco-lingual and mesio-distal convergence angles subsequently calculated. Results: A total of 40 casts having crown preparations (15 anterior, 25 posterior). The mean convergence angles mesio-distally for all preparations was 40.29° (sd 21.8°), and for the bucco-lingual was 29.92° (sd 9.3°), with mean of TOC was 35.10°. In anterior preparations, the mean bucco-lingual convergence angle was 42.32° (sd 12.2°) compared to 24.52° (sd 15.5°) for posterior preparations (p

Abstract Introduction: Provisional restoration is an important part of fixed prosthodontics. It must provide pulp protection, positional stability, occlusion maintenance , and space preservation. There are two methods for provisional restoration fabrication; direct and indirect techniques. Aim: the study aims to identify the most preferred technique of fabricating provisional fixed restorations according to different parameters and situations and to highlight the advantages and disadvantages of each technique, by specialist dentists practicing in different dental clinics in Tripoli. Methodology: In this study, 120 closed ended questionnaires were distributed to specialist dentists in dental fixed restoration among different private dental clinics in Tripoli/Libya to find out which technique they prefer to apply in their clinics. Results: This study has revealed that dentists prefer the direct technique for the anterior area and single unit and up to 3-4 units fixed partial denture. While indirect technique was more commonly used by dentists in cases of multi-units and posterior teeth. In addition, it has a higher success rate and does not cause pulpal and gingival irritation.
