No full textAbstractTooth loss adversely affects patients’ quality of life and causes inevitable changes in the mandibular morphology. Polymethyl methacrylate (PMMA) is the most frequently used material of removable dentures. Denture stomatitis (DS) is a common clinical finding among denture wearers, particularly patients with debilitating diseases. Several fillers and nanofillers have been used to improve the physical, mechanical, antifungal, and antimicrobial properties of PMMA.The aim of the present retrospective cross-sectional study was to determine the prevalence of tooth loss and the commonly used prosthetic constructions in 479 adult patients at the Department of Substitutive Dental Sciences (SDS), College of Dentistry, University of Dammam, currently Imam Abdulrahman Bin Faisal University, Dammam. The influence of tooth loss on mandibular morphology was studied by using cone-beam computed tomographic (CBCT) scans of 101 patients. The effect of addition of thymoquinone (TQ) and nanodiamonds (NDs) to PMMA on the flexural and surface properties of PPMA and their antifungal influence was tested through in vitro studies.Edentulousness was recorded in 6%, a single edentulous arch in 8%, and partial edentulousness in 74% of the patients. Age and diabetes were significantly associated with edentulousness. Males had a significantly higher number of missing teeth compared to females. Kennedy class III was most common in the upper and lower jaw and was treated more often with fixed partial denture (FPD) than with removable partial denture (RPD). Larger gonial angle (GA) of the mandible was found in edentulous patients, in females and in older compared to dentate patients, males and younger patients. The addition of TQ to PMMA at low concentration did not significantly change the flexural strength, elastic modulus or surface properties of PMMA. The addition of NDs to PMMA significantly reduced surface roughness and the Candida albicans (C. albicans) count.Edentulousness increased in old age and caused changes in mandibular morphology. TQ addition at low concentration did not change the flexural and surface properties of PMMA. NDs decreased the surface roughness of PMMA and Candida albicans adhesion, which could help in the prevention of denture stomatitis.Original papersOriginal papers are not included in the electronic version of the dissertation.Fouda, S.

Service Quality in the Finnish Health Care System and Patients’ Decisions
No full textCustomer service is considered an important part of any organization and one which has a direct effect on the organization income and customer satisfaction toward organization efficiency. The value of organization services could change customer attitude. Each customer has his/her expec-tations and customer services could lead to memorable experiences, positive or negative ones and change customer perception towards what the organization offers. The customer or to be more specific healthcare patient, patient satisfaction is related to sharing in the decision making for treatment, care evaluation and cost reduction. The quality of health care services is of utmost importance to society and through research knowledge can be acquired about the importance of quality, concepts and its role in health care development and recommendations can be made to help in its improvement.
In this research the author examines the Finnish healthcare system provision and policy. Research is conducted on client types, preferences and rights, and an understanding of the client’s attitude towards healthcare services and factors affecting their decisions is desired. The author aims to investigate how much the quality of customer service in the Finnish healthcare system could affect customers decisions. Does the experience of challenges in customer services direct custom-er/patient from public healthcare services to private ones or vice versa? The purpose of the thesis project to offer guidance for healthcare professionals to improve the management of the healthcare system. Guidance includes the area which are valued by customers, the painful and joyful moments during the customer journey.
The author’s objectives during the research concern knowledge discovery; to know how much health care facilities put the quality factor in consideration, to be aware health care problems, to understand the different kinds of behaviors from the perspectives of professionals or clients, to summarize the most important elements which should be in any health organization to achieve a high level of quality and to decrease the gape between our needs and what are already offered by the health care

Specific attention is given to the effect of fiber, filler, and nanofiller addition on poly(methyl methacrylate) (PMMA) properties. The review is based on scientific reviews, papers, and abstracts, as well as studies concerning the effect of additives, fibers, fillers, and reinforcement materials on PMMA, published between 1974 and 2016. Many studies have reported improvement of PMMA denture base material with the addition of fillers, fibers, nanofiller, and hybrid reinforcement. However, most of the studies were limited to in vitro investigations without bioactivity and clinical implications. Considering the findings of the review, there is no ideal denture base material, but the properties of PMMA could be improved with some modifications, especially with silanized nanoparticle addition and a hybrid reinforcement system. Keywords: denture base, PMMA, reinforcement, nanoparticles, fibers, filler

Immunization Status in Childhood Cancer Survivors: A Hidden Risk Which Could be Prevented
No full textBackgroundA limited number of studies have examined the vaccine-specific antibody status of children with cancer. There are disagreements over the guidelines for postcancer immunization strategy.MethodsOur study was an observational, cross-sectional retrospective review of data collected on children who were seen in the outpatient clinic at King Abdullah Medical City, Oncology Center, Jeddah, the Kingdom of Saudi Arabia. Our aim was to evaluate the seropositive status to vaccine-preventable diseases: measles, mumps, rubella, diphtheria, tetanus, polio, and Haemophilus influenzae type B (HIB) in childhood cancer survivors at our center in order to plan future vaccination for these children and establish a simple revaccination schedule.ResultsForty-seven patients (21 boys and 26 girls) were included in the study. Age at the time of cancer diagnosis (mean±standard deviation) was 5.68±3.79 years and age at test sampling was 10.68±3.79 years. Acute leukemia was the most common cancer (49% of patients), followed by lymphoma (28%), brain tumors (13%), and solid tumors (10%). Treatment intensities (according to the Treatment Intensity Rating Scale, version 3.0; ITR-3) were 2, 3, and 4 for 26 patients (55%), 20 patients (43%), and one patient (2.1%), respectively. We found that 93% of our patients were considered seronegative (unprotected) for at least one vaccine-preventable disease. The seronegative rates for measles, mumps, rubella, diphtheria, tetanus, polio, and HIB were 46.8%, 36.2%, 36.2%, 46.8%, 61.7%, 17.1%, and 42.6%, respectively. Criteria including age at diagnosis, age at sampling, type of malignancy, and treatment intensity were not significantly different between seropositive and seronegative patients.ConclusionSeronegative rates for vaccine-preventable diseases were very high in childhood cancer survivors, which represented a subpopulation of high-risk patients who could benefit from revaccination. We suggest a universal revaccination approach for all childhood cancer survivors, which is easily applicable and of low cost

Hypovitamininosis D in Childhood Cancer Survivors: Importance of Vitamin D Supplementation and Measurement Over Different Points of Time
No full textNature Influences on Architecture Interior Designs
No full textAbstractConcept is on the most important and primary elements during the design process. Through the history, nature has been always a source of inspiration for the human begin in different aspects of their life. Architecture interiors as one of the remarkable features in every society cannot be separated from nature. Nowadays architects and interior designers are constructing buildings without having a specific target or goal which decreases the value of the buildings. Various designers have been using concepts inspired from nature but still there are some missing parts in one of their forms, function, or structure. Therefore, the best solution for the architects and designers to increase the optimization in their design works is looking at the nature in every aspect deeper and try to apply them in their conceptual design of their project which is the heart of the design process while other architects have neglected concepts of nature despite that the surrounding environment and nature always influences human perception. The aim of this research is to understand the relationship between nature and human perception and the role that nature plays in architectural interiors to achieve buildings integrated with the surrounding environment. Also it draws attention of architects to nature and inspiration from nature in different perspectives. This paper presents projects having different concepts in architectural and interior design to make guidelines for designing buildings integrated with nature through example analysis. This paper concludes the importance of making a complete integration between the building exterior, interior and the surrounding nature by using a clear natural concept from the surrounding environment to be solving the design problems
Contestation and Consensus over Davutoğlu’s Conception of Turkish Regional Power Role in the Middle East (2002-2016)
No full textIn light of ebbs and flows in Turkish foreign policy in the Middle East, this study examines intra-elite disagreement and consensus over former Turkish Minister of Foreign Affairs and Prime Minister Ahmet Davutoğlu’s conception of regional power role since 2002 until 2016. While National Role Conception (NRC) literature has discounted intra-elite disagreements and variations, this study unravels contestations over Turkish regional power role within the AKP leadership and disagreements among the state bureaucracy, the opposition, and civil society from 2002 until Davutoğlu’s resignation in 2016. Building on factors of national role analysis, this study argues that Davutoğlu’s conception of regional power role in the Middle East has manifested elements of contestation and consensus across domestic actors due to variations in ideas, ideology, identity, and structure-agents interactions. This finding dwells on the triangulation of three research methods used in analyzing politicians, bureaucrats, and activists’ statements, declarations, and publications and tracking nuances of consensus and contestation over Turkish regional power role. It also relies on an extensive fieldwork study conducted by the author with Turkish officials in the AKP, opposition parties, and civil society from 2010 until 2015
