Abstract
BACKGROUND Developing efficient bonding techniques for orthodontic brackets and all-ceramic materials continues to pose a clinical difficulty. This study aimed to evaluate the shear bond strengths (SBS) of metal and ceramic brackets to various all-ceramic CAD-CAM materials, such as lithium disilicate CAD (LDS-CAD), polymer-infiltrated ceramic (PIC), zirconia-reinforced lithium silicate glass ceramic (ZLS), and 5YTZP zirconia after different surface treatments and thermal cycling. MATERIALS AND METHODS The samples were divided into two groups to be bonded with ceramic and metal lower incisor brackets. Each group was subdivided into a control group devoid of any surface treatment, 10% HF acid (HFA) etching, ceramic etch & prime (MEP), Al2O3 air abrasion, and medium grit diamond bur roughening. After surface treatment, brackets were bonded with composite resin cement, thermal cycled, and tested for shear bond strength. The failed surfaces were evaluated with a digital microscope to analyse the type of failure. The data were statistically analysed using a one-way ANOVA and Tukey HSD tests at p < 0.05. RESULTS The highest mean bond strengths were found with HFA etching in LDS-CAD (13.17 ± 0.26 MPa) and ZLS (12.85 0.52 MPa). Diamond bur recorded the lowest mean bond strength roughening across all the ceramic groups. There were significant differences in mean shear bond values per surface treatment (p < 0.001) and ceramic materials. CONCLUSION Among the surface treatment protocols evaluated, HFA etching and MEP surface treatment resulted in enhanced bond strength of both ceramic and metal brackets to CAD-CAM all ceramic materials.

Abstract
BACKGROUND A dental dam is a protective sheet with an aperture and is used to prevent the spread of infection during dental procedures. This study aimed to use a 2-part online questionnaire to evaluate the attitudes and use of rubber dental dams by 300 Saudi dental interns, general dental practitioners, residents, specialists, and consultants in prosthodontics, endodontics, and restorative dentistry. MATERIAL AND METHODS The 17-item validated questionnaire consisted of 5 questions on demographics, 2 on knowledge, 6 on attitudes, and 4 on perceptions. It was distributed through Google Forms. The chi-square test was used to determine the associations between the study variables and perception questions. RESULTS A total of 41.67% participants were specialists/consultants, among which 59.2% were in the prosthodontics specialty, 12.8% in endodontics, and 28% in restorative dentistry. Most participants (84.67%) stated the necessity of using rubber dams during post and core procedures. A total of 53.67% had received enough training for using rubber dams during their undergraduate/residency education. The majority of participants (41%) also preferred using rubber dams during the prefabricated post and core procedures, and 28.33% stated that the remaining tooth structure was one of the major reasons for not using rubber dams during the post and core procedures. CONCLUSIONS Workshops and hands-on training should be conducted among dental graduates to instill a positive attitude regarding the use of rubber dams.

Abstract
OBJECTIVE Adverse drug reactions (ADRs) are widespread worldwide, and their intervention is critical to patient safety and healthcare quality. Pharmacists are essential in monitoring and reporting ADRs, directly influencing patient care. This study aimed to examine the prevalence of ADRs among pharmacists and their knowledge regarding ADRs, including the factors affecting ADR reporting. SUBJECTS AND METHODS From September 2021 to November 2021, a cross-sectional survey among pharmacists in the Asir area of Saudi Arabia was planned. This study involved contacting 97 pharmacists using a cluster sampling method. The study's goals were met using a 25-item self-administered questionnaire. Data analysis was done using SPSS version 25 (IBM Corp., Armonk, NY, USA). RESULTS Ninety-seven pharmacists (male 53.6% and female 46.4%) completed the survey. More than three-fourths of the participants (78.4%) know the ADR reporting system. The survey was completed by 97 pharmacists (male 53.6% and female 46.4%). More than three-quarters of the participants (78.4%) were aware of the ADR reporting system, and the majority (70.8%) were aware that it is done using an online system. Still, only 56.7% knew that the Saudi FDA is the regulatory agency collecting ADR data in Saudi Arabia. Furthermore, 73.2% cited stress in the workplace as a critical deterrent to reporting. Most respondents (76.3%) had an unfavorable attitude about reporting ADRs. CONCLUSIONS Pharmacists understand ADR reporting, but most lack the mentality to report the incidents. As a result, comprehensive and ongoing training for pharmacists is required to raise awareness of the need for ADR reporting.

Abstract
BACKGROUND This systematic review aimed to identify and evaluate publications using the Dundee Ready Educational Environment Measure (DREEM) and its domains, genders, and educational level (EL) to monitor the education environment in medical colleges (MCs), applied medical science colleges (AMSCs), and dental colleges (DCs) in Saudi Arabia (SA). MATERIAL AND METHODS A literature search was performed using PubMed, ScienceDirect, Scopus, Wiley Library, and Web of Science database keywords and medical, applied medical science, dental colleges headings, followed by a summary and analysis of results. We included all related studies that used DREEM as a tool and were published up to 2022. The following information was extracted from the included studies: researcher's name(s), publication year, overall DREEM, domain, gender, and educational levels. RESULTS Among the 40 studies included in this review, 25 papers were conducted in medical colleges, 5 in applied medical science, and 10 in dental colleges. Overall, DREEM scores among all involved colleges were "more positive than negative," with scores between 101 and 150. In relation to the 5 domains of DREEM, the percentages of medical colleges ranged from 75% to 88% for all domains, whereas it was higher in dental (80% to 90%) in most domains, but considerably lower for applied medical science (50% to 75%). Females had higher DREEM values in dental than medical and applied medical science colleges, whereas educational levels were higher in applied medical science colleges. CONCLUSIONS Overall, DREEM scores were more positive than negative and moved in the correct direction among all involved colleges, with varying degrees of significance between genders and educational levels.

Abstract
OBJECTIVE The aim of this study was to compare the periapical status of different teeth by using the Periapical (Pa) and the cone beam computed tomography (CBCT) radiographs. PATIENTS AND METHODS Pa and CBCT radiographs were obtained from the patients who required Endodontic treatment. The absence and presence of periapical lesions were investigated using both Pa and CBCT radiographs. Periodontal conditions other than periapical lesions were also observed by using both radiographs and recorded. Cohen's Kappa analysis was performed to observe the inter-rater and intra-rater reliability. Descriptive statistics including frequency and percentages of presence and absence of periapical lesions were analyzed. Independent t-test was conducted to compare the Pa and CBCT for the detection of periapical lesions. Chi-square test was used to investigate the distribution of gender and periapical lesions by both radiographs. RESULTS A total of 204 teeth from 72 patients (29 female and 43 male) were assessed via CBCT and Pa radiographs. Inter-observer and intra-observer reliability showed the absolute level of agreement. T-test showed there is significant difference between Pa and CBCT radiographs regarding detecting periapical lesions. Chi-square test showed no significant differences between the gender and apical pathosis. CONCLUSIONS CBCT is more reliable to detect periapical lesions compared to the Pa radiographs.

Abstract
OBJECTIVE Understanding the labial alveolar bone thickness (ABT) and buccolingual teeth angulation may reduce the complication that might arise during or post-operative treatment. The operator could determine the precise method to ensure long-term treatment success. This study aimed to evaluate the ABT with buccolingual upper incisor teeth angulation based on the maxillary plane by using the cone-beam computed tomography (CBCT). MATERIALS AND METHODS A total of 371 CBCT radiographs were initially assessed and 100 CBCT radiographs were included. On the maxillary incisors, the labial alveolar bone thickness is evaluated at three points (Point A: Four mm below from CEJ, Point B: Midpoint from the labial alveolar-palatal alveolar crest plane and root apex. Point C: Root Apex of the tooth). The distance from these points to labial alveolar bone was measured for the ABT. Moreover, buccolingual angulation of the tooth was measured by the angle formed by the maxillary plane and the long axis of the tooth. RESULTS There is no significant difference observed between genders in the labial alveolar bone thickness. The labial alveolar bone thickness grew gradually from the cementoenamel junction (CEJ) level to the apical level. Moreover, there was a statistically significant positive correlation observed between labial alveolar bone thickness at the apical level (Point C) and angulation (p<0.05). CONCLUSIONS The labial bone thickness was less than 2 mm in the majority of cases at the three points among maxillary incisors. In addition, there is a correlation between buccolingual angulation of the maxillary incisors and labial alveolar bone thickness.

Abstract
OBJECTIVE Breast cancer is the most common malignancy in Kingdom of Saudi Arabia (KSA) and an increasing burden in terms of incidence, morbidity and mortality. It accounts for about 28.7% of all new cancers in women. In 2015, the Saudi cancer registry shows that breast cancer was graded first among women and it accounts for 16.7% of all cancers reported among Saudi nationals. This study was designed to assess breast cancer screening knowledge and practices among women in the Asir region, Kingdom of Saudi Arabia. MATERIALS AND METHODS A cross-sectional study recruiting 1,021 female participants was performed. The variables included breast cancer knowledge, socio-demographic features, breast self-examination knowledge and practice. Descriptive statistics was used to compare and analyze the collected data while chi-square test was used to check the statistical significance among the selected variables. Saudi married women from Asir region were the participants of this cross-sectional study. RESULTS Our findings suggested that participants had a satisfactory level of knowledge about breast self-examination and mammograms at a rate of > 90% and 44.76% respectively. Over 90% of participants had good breast self-exam knowledge, however, only 6.37% was always performed breast self-examination. Similarly, nearly 40% of participants performed mammograms, while 40.5% were unaware. Leaflets and doctors were the primary sources of information for participants regarding the information of breast cancer screening. CONCLUSIONS Breast self-examination is a crucial approach to the timely detection of breast cancer and is subsequently critical for effective treatment. From the findings of this study we concluded that most women in the Asir region have a good awareness of breast cancer screening methods. However, either screening of self-examination or mammogram for breast cancer was not carried out thoroughly and regularly. This means that we must continue to emphasize the importance of primary health care in the earliest stages of breast cancer.

Abstract
OBJECTIVE Cardiovascular disease (CVD) is the most common non-communicable disease and the leading cause of death worldwide. To reduce the global burden of CVD and related morbidity and mortality, early prediction of CVD risk is essential. Various tools are available to access the risk of cardiovascular disorders. In the present study, we evaluated four risk score calculators associated to CVD for superiority and most reliable CVD prognosis parameters. PATIENTS AND METHODS In the present prospective study, we investigated the probability of CVD in 150 individuals, including both men and women, using four different cardiovascular risk assessment estimators (Framingham Risk Score [FRS] Calculator, Q-RISK calculator, Reynolds score calculator, and atherosclerotic cardiovascular disease (ASCVD) risk calculator) and evaluated how closely they were related to 16 selected parameters. The four risk estimators shared several common parameters, such as age, smoking status, and blood pressure; however, each of them also used some unique parameters. We used statistical analysis to reduce the number of parameters necessary to predict CVD. RESULTS Statistical analysis revealed a significant correlation between the main factors responsible for CVD risk. The analysis revealed that out of the four risk calculators tested, the FRS calculator was superior to the others because it showed more significant corroboration with statistical tools and could better predict the most important prognostic factors in CVD. CONCLUSIONS In all four risk estimators, the parameters that affected risk most significantly and conferred the most reliable CVD prognosis were age, weight, total cholesterol, and hemoglobin levels. With that FRS calculator was superior to the others.

Abstract
Background Temporary stage in crowns and bridgework plays an important role in the success and failure of the final restorations. Lack of marginal seal of the temporary restorations can lead to further complications. Recently, digital dentistry has been improved in terms of marginal integrity. Aims The aim of this study was to evaluate and compare the marginal leakage between CAD/CAM and conventionally made Polymethyl methacrylate (PMMA) interim crowns cemented with different temporary luting cements. Materials and Methods Sixty resin dies of a maxillary right first premolar were prepared according to the protocol of the tooth preparation for all-ceramic crown. Interim crowns were then fabricated and assigned to two main groups according to the fabrication technique (CAD/CAM technique and conventional technique). Furthermore, the samples were sub-grouped (n = 10) according to the type of the luting cements: Zinc oxide eugenol (RelyX temp E), Zinc oxide non-eugenol (RelyX temp NE), and Zinc polycarboxylate cement (pentron). The specimens were then subjected to thermocycling at 5°C and 55°CC for 30 sec and transfer time of 15 seconds for 1500 cycles. After that, the specimens were immersed in a 2% methylene blue solution for 24 hours. The cemented specimens were sectioned buccolingually and the amount of marginal leakage was evaluated under digital microscope at magnification 50x. The scores of dye penetration were recorded and analyzed using one-way ANOVA at P < 0.05 for all tests. Results For the fabrication technique, CAD/CAM-made interim crowns had significantly better performance in terms of lower microleakage in comparison to conventionally built interim crowns (P < 0.001). Overall, Zinc Oxide non-eugenol also showed significantly least microleakage as a luting cement then Zinc Oxide Eugenol and the most microleakage was found with Zinc Polycarboxylate regardless of the fabrication method. Conclusion Interim crowns fabricated by CAD-CAM system are better suited for temporization. Zinc-oxide non-eugenol cements showed the least amount of microleakage in both types of crown.

Abstract
Major depression disorder (MDD) is an extremely prevalent disorder and is expected to be the second leading cause of disease burden by 2020 according to the World Health Organisation (WHO). Moreover, this disease burden is predicted to rise in the next 20 years. Antidepressant medications are vital in the therapy of major depression. However, approximately 30-60% of patients treated with current antidepressant drugs fail to attain remission of depressive symptoms leading to drug resistance. Such patients account for a disproportionately great burden of disease, as supported by cost, augmented disability, and suicidal incidents. Antidepressants resistance remains to challenge mental health care professionals, and more relevant research relating newer medications is necessitated to enhance the quality of life of patients with depression. Enhancement in response rates continues the major challenge in antidepressant research, thus a wealth of potentials still exists concerning the antidepressant resistance for the management of major depression. However, the mechanisms causing resistance to antidepressant treatment remain unknown. Hence, clinical and basic research in understanding the fundamental mechanism of antidepressant resistance should remain a key priority. One potential source accounting for these differences in treatment outcome is genetic variations. The pharmacological mechanisms behind antidepressant response are only partly known but genetic factors play a significant role. Future research of risk factors should assist to advance the understanding of the mechanisms underlying drug resistance in mood disorders and contribute to progress their therapeutic management. Thus, psychiatrists could rely on more effective approaches to treat depressive episodes, reducing the incidence of further drug resistance. This review critically summarises the author's view on many aspects of treatment resistance, specific genetic biomarkers, potential strategies and clinical relevance from both clinical and preclinical studies in drug resistance to antidepressant therapies. Finally, this will allow us to suggest possible recommendations and innovative treatment strategies to improve therapeutic outcomes in managing antidepressant resistance.
