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.

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.

Background: Management of partially edentulous patients with hard and soft tissue undercuts is complicated, and the use of flexible dentures for these cases offers dual advantages of aesthetics and flexibility. However, research shows a varying preference for flexible dentures among general dental practitioners, prosthodontists, and other dental specialties. Objectives: The aim of this study was to survey the attitude and awareness of a sample of Libyan dental clinicians towards advantages, disadvantages, indications, and contraindications of flexible dentures. Material and methods: A descriptive cross-sectional study was conducted among 250 dentists currently practicing in different cities of Libya. Only 218 dentists responded. Using Google form software, a self-administrable e-questionnaire consisting of thirty-one multiple choice questions with "yes," "no" or "not sure" answers encompassing major aspects of flexible dentures was conducted through an online survey. Results: Out of 250 Libyan dentists to whom the questionnaire was sent, only 218 dentists responded and our results revealed that the respondents were females more than males with a ratio (2:1) and more than half of them were of age group (35-60 years) work in governmental dental practice with more than ten years of experience and 34.9% of them prefer and often offer flexible dentures to their patients. The majority of respondents with a long-term success of the flexible denture were prosthodontists who had more than ten years of experience with a correct response rate of more than 50% of questions that reflected their attitude and knowledge. Conclusions: Despite the fact that flexible dentures are not taught in Libyan universities of dentistry, about more than one-third of respondents prefer and recommend this treatment to their patients, and the long-term success of these prostheses was dependent on clinicians' education and their clinical experience.
