Evaluating and Improving the Assessment and Consistency of Feedback within the Clinical Skills Laboratory at Dundee Dental School

Conservative and fixed prosthodontic concepts and techniques are introduced to second and third year dental students through participation in a clinical skills laboratory courses at Dundee Dental School. These courses contain a didactic portion during which learn the theoretical aspects of conservation and fixed prosthodontics. Throughout the UK, students rely on different interpretations by different Dental Schools of conservation and fixed prosthodontic methods multiple for application, reinforcement and enhancement of theoretical principles during a simultaneous laboratory portion of the courses. School examiners teaching the courses are expected to provide consistent formative and summative feedback of the student performance. Low reliability of examiners may lead to student confusion and frustration (Haj-Ali and Feil, 2006). Therefore, the maxim “Assessment drives learning”(Miller, 1990, Wass et al., 2001, Manogue et al., 2011, Norcini et al., 2011, Vander Vleuten et al., 2012), can be used to understand the problem provide at least a partial solution. In summary, student learning to determine the clear nature of the problem, analyse the problem in detail and the skills to solve the problem, are essential to motivate the student to learn. This thesis is focused on the assessment and feedback of student performance in order to identify the most common problem. In further chapters, clarification and further definition the problem will be reported clearly. Then, researcher will conclude whether or not the problem can ultimately be solved. If the problem is defined poorly or not completely understood, it is much more difficult to solve than a problem …

A to Z instruments and Equipments for fixed prosthodontics

This book was designed to provide dental students an overview about the instruments which used in fixed Prosthodontics. It is useful as a revision and reference tool. It is also prepared to be easy to read for dental students and general dental practitioner. The book aimed to enhance the knowledge and understanding the application of the instruments and equipment used to make crowns and bridges from the beginning of the diagnosis stage till the delivery of final restoration. Dental practitioner must have a thorough background about the knowledge and function of each instrument to be used in fabrication of a fixed partial denture as a first step in the patient treatment.

Perspective and practice of root caries management: A multicountry study – Part II: A deeper dive into risk factors

Background: The potential of an improved understanding to prevent and treat a complex oral condition such as root caries is important, given its correlation with multiple factors and the uncertainty surrounding the approach/material of choice. Deeper insights into risk factors may improve the quality of treatment and reduce the formation of root surface caries. Aim: The present work aims to gain knowledge about dentists' opinions and experiences on assessing the risk factor related to the development of root caries and to help identify any overlooked factors that may contribute to less efficacious clinical outcomes. Methodology: A questionnaire related to root surface caries was distributed among practicing dentists in nine different countries, namely the United Kingdom, Libya, Jordan, Saudi Arabia, Egypt, Brazil, India, Malaysia, and Iraq. Questionnaire responses were analyzed, and the results were compared among the groups. Results: Dentists around the world ranked the oral hygiene status of patients as the most important factor in the development of root surface caries. Patients with poor oral hygiene, active periodontal disease, reduced salivary flow, and gingival recession are perceived to have a higher risk of developing new root surface caries. There is a greater focus on prevention in the UK and greater levels of untreated dental disease in other countries, especially those recovering from civil wars. Conclusion: This work identified some overlooked factors that may have contributed to the less efficacious clinical outcomes reported in the literature. It is hoped that this deep dive into risk factors coupled with the findings presented in Part I of this study will be used as a basis for a more comprehensive investigation into the management of patients with root surface caries.

Perspective and practice of root caries management: a multicountry study – Part I

Every effort needs to be made to better understand the current state of practice and trends relating to root caries management which will be of benefit to dentists universally in the practice of dentistry. Aim: This article presents a multicountry questionnaire survey of the current state of practice in the management of root caries among dentists in nine different countries to get a wider range of opinions and perspectives. Methodology: A questionnaire related to root surface caries was distributed among practicing dentists in nine different countries, namely the United Kingdom, Libya, Jordan, Saudi Arabia, Egypt, Brazil, India, Malaysia, and Iraq. Questionnaire responses were analyzed, and the results were compared among groups. Results: The results showed statistically significant differences among dentists in most questionnaire aspects. Bleeding is the greatest obstacle facing dentists when restoring root surface lesions. Reported survival rates reflect uncertainty about the material and/or approach of choice in the management of root surface caries. Conclusion: This questionnaire survey revealed the current status of management of root surface caries in clinical practice in various countries. Substantial attention is required to bridge the knowledge gap and address the current void of uncertainty as relates to root caries management by providing a common ground for communication between dentists from all around the globe. In all, this work found a degree of consensus at the international level on what appears to work well among the dental practices surveyed and identified several issues with existing approaches that need to be addressed in future studies.

Comparison between Unstructured oral examination "UOE" and Objective Structured oral examination "OSOE" in department of fixed prosthodontics/dental faculty university of Tripoli

Aim: the aim of this study was to compare reliability of two different oral exam examinations commonly used alternatively in Dental school of Tripoli university (Objective Structured Oral Exam, and Unstructured Practical Oral exam.).Methodology: The method that has been adapted in this study were clinical and self-structured questioner, and statistically a descriptive and inferential statistical analyses was used, the relative variation,Pearson's correlation test, and "ICC" i.e. Interclass Correlation Coefficient respectively...i.e. quantitative, descriptive correlation study, Result: the inferential statistical analyses yielded a “coefficient of variation” value for R1U and R2U and for R1S and R2S as (28.455, 34.930) and (10.870, 16.028) respectively. Cronbach's alpha reliability was found (0.455) for R1U and R2U raters and (0.951) and was (0.463)R1U and R2U, and for R1S and R2S was significant (P0.001) with value of (0.951 which rated excellent). Bivariate correlation was significant and with value of (0.906test for Structured oral exam, and was not significant with value of (0.054) for unstructured oral. Conclusion: We concluded that the Structured oral exams is more reliable than unstructured oral exam.

CLINICAL EVALUATION OF FAILURE RATE OF CROWN AND FIXED PARTIAL DENTURE IN TRIPOLI CENTRAL DENTAL CLINIC

ABSTRACT The aim of this denture study was to document the failure rate and length of service of crown and fixed partial bridge (FPD) in Tripoli Central Dental Clinic- Libya. Also the number of retainers, pontics, and the types of restoration were recorded. By examining 78 patients with 306 crown and bridge unites from the Tripoli Central Dental Clinic and collecting data related to the bridge area the data collated were subjected to descriptive analysis. The result of the study revealed that the pain was the most frequent complication observed on 36% of all the patients while aesthetic was the lowest with less than 2% of the patients.
