Nicotiana glauca belonging to the family Solanaceae is an exotic perinnial bushy species that recently has invaded the mountainous areas of Al-Baha region at the south-west of Saudi Arabia, causing degredation to soil and vegetation composition of those mountains. Accordingly, this plant must be either removed or exploited as a source of useful products such as medicines as it has been proven to contain many effective compounds with therapeutic properties. Thus, the current study aimd to screening N. glauca preliminary phytoconsitiuents and its anticmicrobial activity. Results showed that varying amounts of alkaloids, steroid, tannins, flavonoid, were present in the extracts of N. glauca leaves, stems and flowers. Saponins were present only in the flowers extract. However, all previuos bioactive compounds were absent in the roots except alkaloids, therefore, roots posses lesser amount of the phytoconstituents compared to the other parts of the plants. Leaves extracts inhibited the growth of E. coli (16.3 ± 0.71 mm) and also inhibited the growth of S. aureus (11.0 ± 0.23 mm), while, the flower extracts also inhibited the growth of E. coli (6.7 ± 0.65 mm), and also inhibited the growth of S. aureus (15.8 ± 0.52 mm). This result coincide with the previous results of the screening of N, glauca phytochemicals where the highest amounts found in leaves and flowers extracts. The inhibition zone of the antibiotic gentamycin (reference control) were 32 mm in S. aureus and 38 mm in E. coli. The inhibition zone of gentamycin (reference control) were 32 mm in S. aureus and 38 mm in E. coli. The minimum inhibitory concentration (MIC) of ethyl acetate was ranged (1.5–2 mg/ml). The lower MIC is an indication of high effectiveness of extract. Therefore, such bioactive property would support the idea that removing N. glauca from the mountainous areas of Al-Baha, Saudi Arabia, is not the only solution, but the plant can be exploited as a beneficial source of medicinal and economic purposes such as; antibacterial, antifungal and insecticidal, however, further comprehensive exploration is recommended to confirm such propreties.

Statement of problem: Prosthodontics has received significant attention both in research and practice. However, limited research examines its prevalence and how effective it is. Purpose: The purpose of this clinical study is to examine the prevalence of prosthodontics and its associated complications Material and methods: A sample of 1005 individuals derived from the general Saudi Arabia was used in this study. Data was collected using a questionnaire. The data collected was analyzed using SPSS. Results: There is a generally low prevalence of prosthodontics in Saudi Arabia. The common type of prosthodontics used is the fixed prosthodontics. Majority of those who have done prosthodontics didnt suffer any associated complications. However, for those who depicted complications, the common one was caries. Other complications include root fracture and porcelain veneer fracture. Conclusion: Prosthodontics is not widely used. On the other hand, it is not 100% effective in treating oral health problems. Clinical implications: There is need to develop better ways of dealing with poor oral health and patients need to be examined well to determine the underlying risk factors before prosthodontics is carried out.

Background: Hypertension is common in Saudi Arabia, and its prevalence is rising, yet it remains inadequately controlled. Few studies could characterize the epidemiology and management of hypertension across many heterogeneous subgroups. Therefore, the present study aimed to estimate the proportion of adults with hypertension who have been screened and to determine the status of hypertension awareness of the general adult population in Saudi Arabia. Methodology: This was a cross-sectional study conducted among 1,000 adults who were 18-year old and above, during a period of 3 months (May to August 2019) to explore the awareness regarding risk factors, management, preventions of hypertension complications among the Saudi population. Data were collected by a previously standardized structured questionnaire with closed-end questions. Results: Out of the total participants, more than half were males (57.4%) and most of them (81%) resided in the urban areas. The results indicate a higher level of hypertension awareness among males and rural participants. Conclusion: A higher prevalence of hypertension among males was reported, who were young adults less than 35-year old, having normal body mass index, and were urban residents. The awareness level was higher among males and rural participants than females and urban ones.
