ABSTRACT
BACKGROUND: The Cone Beam Computed Tomography (CBCT) is currently being used as the most common diagnostic method to evaluate the bone density of the maxilla and the mandible for planning dental implant. Aim: The aim of the study is to check the quantitative alveolar bone density in complete or partial edentulous and dentulous male and female patients among Riyadh sample population in Saudi Arabia. MATERIALS AND METHODS: The study involved a cross-sectional analysis of 231 consecutive CBCT images of 231 different patients (115 males and 116 females). The scans were of Saudi National patients who were partially or completely edentulous without any bone infections in the maxilla and the mandible. The findings are presented as descriptive statistics and inferential statistics: student -t-test for two group means, ANOVA for three groups, Post-hoc LSD test for multiple comparisons, Levene statistics for testing the homogeneity of variances and a statistical significance at 5% level. RESULTS: Comparison of mean alveolar bone density in maxillae of dentulous male smokers showed a statistically significant difference for bucco-cortical plate and cancellous bone among different regions. In dentulous male nonsmokers, no significant difference was observed for maxillary regions, while in mandibular areas, a statistically significant difference was seen for buccal cortex, palatal cortex, and cancellous bone among different regions. While studying the scans of female dentulous patients, a statistically significant difference was observed in alveolar bone density for all the areas. CONCLUSION: Evaluation of bone density is an important step in treatment planning and this study was aimed to provide insight into bone density patterns of population in Riyadh, Saudi Arabia. Further similar studies in different populations can help in planning for more efficient treatment outcomes.

This study investigated medical students' study habits and perceptions of learning difficulties during their first year of study. A specially-designed questionnaire was answered by 165 second-year medical and medical science students at Umm Alqura University in Saudi Arabia. Out of the 7 difficulties listed in the questionnaire, students ranked peer competition first, followed by poor English language skills. Male students ranked peer competition as the top difficulty whereas females ranked it fourth. A majority of students were dissatisfied with the passive, lecture-based method of teaching and wanted the English language curriculum to be improved by more emphasis on conversation skills. Early introduction of the concept of active learning and effective studying habits is needed.
ABSTRACT
To determine knowledge and skills competencies in internal medicine for the undergraduate curriculum in Saudi Arabia, competencies were identified based on group work utilizing common textbooks. The Delphi Technique was used as a consensus method to determine and prioritize competencies in internal medicine. A group of 20 clinicians rated the identified competencies from 0-3 (0: no need to know, 1: interesting to know, 2: should know and 3: must know). After formulating the results, a second Delphi round was conducted with 5 experts in internal medicine. A total of 1513 knowledge competencies and 189 skills competencies were determined and prioritized. The competencies corresponded to the 12 systems in internal medicine. All competencies rated 2.2-3.0 were produced separately and considered core competencies for the undergraduate internal medicine curriculum. Determining and prioritizing competencies should influence the curriculum reform process.
