Methods: VR software for panoramic anatomy was developed. Sixty-nine firstyear dental students were divided into a control group (lecture-based) and an experimental group (VR) to learn panoramic radiographic anatomy. Both groups were then tested on knowledge via a 20-question quiz. Student feedback on VR experience was collected via an online survey. Results: There was a statistically significant difference between lecture-based and VR students in the correct identification of anatomical landmarks. Lecturebased students scored higher in identifying the ear lobe, hyoid bone, condylar neck, and external oblique ridge, whereas VR students scored higher in identifying zygoma (Chi-squared test, p < 0.005). The VR group reported high evaluation on all perception items of the online feedback survey on their experience (Student t-test, p < 0.005). Conclusions: Lecture-based students generally showed better performance in panoramic radiographic anatomy. Several structures were not correctly identified in both groups of novice students. The positive feedback of VR experience encourages future implementation in education to augment conventional methods of radiographic anatomy in dentistry with considerations to repeated exposures throughout undergraduate dental education.

This survey aimed to investigate attitudes and current practice of dentists in Riyadh, Saudi Arabia regarding chair-side CAD/CAM technology. An online questionnaire was prepared and sent to a convenience sample of dentists in Riyadh. Questions related to practice aspects of chair-side CAD/CAM system, attitudes and training were presented. A total of 114 questionnaires were completed (77.6% response rate). Study population comprised dentists of a wide range of clinical experience who are working in the various regions of Riyadh city, Saudi Arabia. Of the participants, 27.2% indicated the presence of a chair-side CAD/CAM system at their current workplace and 57% used the chair-side CAD/CAM in the fabrication of dental crowns. The vast majority of participants (81%) believe that the overall quality of chair-side CAD/CAM restorations is at least as good as th...

The objective of this study is to detect the antibacterial activities of aqueous and methanolic extracts of Areca catechu against Escherichia coli and Staphylococcus aureus.Manystudies showed different antibacterial activity, depending on the Areca catechu extracts method, concentration, and the bacterium under test. The aqueous and methanolic extracts were added to growth medium of Escherichia coli or Staphylococcus aureus. The antibacterial activities of the attained fractions were assessed using agar-well diffusion test. In this study we have observed that the Methanolic extract inhibited the growth of Escherichia coli or S...

It arises most commonly among HIV-infected individuals. We present an intra-oral KS in an 80-year-old Saudi male patient, who is HIV-seronegative, nonimmunosuppressed, and with no history of organ transplantation. The patient was treated with fractionated radiation therapy, and had no recurrence in the 48 months of follow-up. The clinical disease, histologic features, and treatment modality used, as well as the relative literature are presented in this paper.

In this cross-sectional study, a questionnaire was administered to dental students and recent graduates of Ajman University (n = 132). Completed questionnaires were received from 84 (63.6%) females and 48 (36.4%) males which included fifth-year students (n = 80), interns (n = 39), and dental practitioners (n = 13). This questionnaire was designed to assess the respondent’s ability to detect and recognize different types of oral lesions, as well as their knowledge of oral cancer appearance and malignancy potential. The overall accuracy of diagnosis was 46%. The participants correctly identified normal variations, benign tumors, malignant tumors, and premalignant lesions at rates of 60.3%, 31.0%, 55.7%, and 33.4%, respectively. There was no significant difference between the two genders in their a...

With the exception of the link between Helicobacter pylori and stomach cancer, other supposed links have been ignored. A wide range of bacteria and other non-virus microbes, including fungi, have been implicated over the years in oncogenesis, as well as the ability to induce inflammation, which may cause cancer. It seems that there is no single "cancer germ," as most bacteria can apparently induce cancer. Here, the role of bacteria and other non-virus microorganisms and oral cancers will be discussed. By ignoring bacteria as a causal agent of cancer, we set back our understanding of this crucially important disease and, as a result, have hindered the development of potential cures.

In many developed countries, KD has replaced rheumatic heart disease as the leading cause of acquired heart disease in children. Among the classical criteria for a diagnosis of KD are oral manifestations such as strawberry tongue, erythematous cracked lip, and oropharyngeal mucositis. We report the case of a 24-year-old Saudi female with a history of Kawasaki disease who presented to our oral medicine clinic with recurrent painless swelling of the upper lip. As lip swelling has not previously been reported as an oral manifestation of KD, this case represents a novel presentation of recurrent Kawasaki disease in an adult female.

In Saudi Arabia, there is a lack of nation-wide epidemiological studies characterizing oral malignancies. Objective: To describe the demographic, clinical and histopathological pattern of the oral cancer cases obtained from the archives of College of Dentistry-King Saud University. Methodology: Data were collected from the histopathology laboratory archives of College of Dentistry, King Saud University over a period of 21 years (from 1989 to 2010) in regard to clinical and histopathological data. Data were recorded and statistically analyzed. Results: Sixty cases of oral squamous cell carcinoma were reported, representing 1.85% of a total of 3,233 cases accessioned. The mean age was (50 years) with 1.6:1 male to female ratio. The tongue represented 30% of the cases. Alveolus and gingiva (...

Perhaps the obvious answer is that, someone else would have discovered penicillin during the 1930s and the Oxford group, would still have purified it sometime in the early 1940s Here, however, in this counterfactual account of the penicillin story, it is argued that without Fleming, penicillin might still be undiscovered and the antibiotic age would never have dawned. As a result, many of the recent developments in medicine, such as organ transplantation, might have been delayed or, at best, made more hazardous. Penicillin might have come onto the scene a few years later but, had Fleming overlooked the discovery, it seems certain that penicillin would not have saved countless Allied lives, during and after D-Day. Instead of having enjoyed fifty and more years of the antibiotic age, it is argued here, that we would have had to rely upon highly developed sulfonamides, so-called "supasulfas", and other chemically-derived antibacterial drugs. Indeed, it might be the case that, even well into this new millennium, the antibiotic age has yet to dawn, and medicine is still waiting for someone to chance upon penicillin.

However, there seems to be either deficiency in knowledge or little intention by general dental practitioners to adopt these principles. The aim of this study was to assess the knowledge and attitude among general dental practitioners towards minimally invasive dentistry in Riyadh and AlKharj cities of Saudi Arabia. Self-administered structured questionnaires were handed to general dental practitioners (GDPs) in the cities of Riyadh and AlKharj in Saudi Arabia. Several questions, including Likert-type scale response categories (1-5), were used. The questions assessed the respondents&amp;amp;amp;amp;amp;#39; levels of agreement regarding diagnostic, preventive and restorative techniques such as use of caries risk assessment, use of high fluoride tooth paste, Atraumatic Restorative Treatment and tunnel preparations. Out of 200 respondents, 161 GDPs with overall response rate of 80.5% completed the questionnaires. The GDPs showed significantly different approach with regards to the use of sharp explorer for caries detection (p = 0.014). Almost 60% of the participants had received no special education regarding minimally invasive procedures. Moreover, GDPs who had received MID training showed significantly better knowledge and attitude in adopting minimally invasive techniques for both diagnosis and treatment of dental caries. Although GDPs possess knowledge about the benefits of MID; however, study showed deficiencies in their attitudes towards caries detection methods and application of minimally invasive dentistry procedures.
