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.

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

Aims: This study assessed the pattern and adequacy of information given to consumers on over-the-counter medications dispensed in community pharmacies in Tripoli, Libya, and compared the performance of pharmacists and non-pharmacists. Methods: This was a cross-sectional survey of private community pharmacies conducted in 2018 . Trained simulated patients were used to collect data on over-the-counter medications dispensed for hypothetical common cold symptoms and the information given by the pharmacy staff on the medication. This information included: name and the strength of the medication, indication for use, duration of use, dosage, how often to take the medicine, timing (before/after/with food), storage, expiry date, and side-effects of the medicine. Time taken to deliver the information was recorded. The adequacy of information provided by the pharmacists and non-pharmacists was compared. Results: A total of 169 pharmacists were surveyed. There were no significant differences between pharmacists and non-pharmacists in information given on the dispensed medications, except for information on taking the medication with food or not (84.5% of pharmacists gave this information versus 57.1% of non-pharmacists; P = 0.001) and on potential side-effects (39.4% of pharmacists versus 20.3% of non-pharmacists; P = 0.014). Significantly more pharmacists (85.9%) than non-pharmacists (61.2%) provided the medication-related information in less than 1 minute (P = 0.001). Conclusion: The inadequate information on medications provided by pharmacists is a concern for patient safety. Health regulatory organizations need to promote safe medication practices.
