The data obtained from the survey were then subjected to a comparative statistical analysis. The inter-group statistical comparison of the distribution of categorical variables was tested using the chi square test or the Fisher's exact probability test if more than 20% of the cells had an expected frequency of less than 5. The p-values > 0.05 were considered statistically significant. The data were statistically analyzed using Statistical Package for Social Sciences (SPSS version 22.0, IBM Corporation, USA) for MS Windows.Results: The response rate was 83.3% for G1 and 63.33% for G2. Of the participants in G2, 39.5% had 1– 5 years' clinical experience (the participants in G1 had no clinical experience). The number of endodontic emergency patients seen per day was significantly higher in G1 (88% and 63.2% of the participants in G1 and G2, respectively, were seeing 0– 3 endodontic emergency patients per day). There was an insignificant difference between G1 and G2 in awareness of the existence of antibiotic prescription guidelines in endodontic therapy (57.9% and 56.0%, respectively; p > 0.05). There was also an insignificant difference between the groups in the rate of antibiotic prescription for endodontic problems, with 84% of the G1 participants and 86.8% of the G2 participants prescribing antibiotics only for limited patients. In the analysis of the clinical-vignette items (Q11– 16), it was found that the rate of antibiotic prescription did not significantly differ between G1 and G2 (p > 0.05). No significant difference was found in the rate of antibiotic prescription for symptomatic reversible pulpitis, symptomatic irreversible pulpitis, and chronic apical periodontitis cases (p > 0.05). In contrast, the rate of antibiotic prescription for the symptomatic apical periodontitis, acute apical abscess, and systemic complications cases differed significantly (8% for G1 and 18.4% for G2, 54% for G1 and 76.3% for G2, and 98% for G1 and 73.7% for G2, respectively).Conclusion: No significant difference in the rate of antibiotic prescription was found between the DIs and GDPs in this study. However, both groups showed an inappropriate rate of antibiotic prescription for some endodontic conditions. Further and more extensive studies involving a wider geographical region and different colleges of dentistry in Saudi Arabia are recommended.Keywords: antibiotic in endodontics, antibiotic prescription, antibiotic over-use, antibiotics

PurposeBased on the intellectual capital (IC) theory and the resource-based view (RBV), the paper seeks to elucidate the direct and indirect relationships between IC and competitive advantage in small and medium enterprises (SMEs). Therewithal, besides examining the mediating role of innovation capabilities in the IC-competitiveness link, it scrutinizes the moderating effect of entrepreneurial orientation in causing IC to boost competitiveness in SMEs through flourishing innovation capabilities.Design/methodology/approachData were collected from 206 participants working in SMEs operating in the Kingdom of Saudi Arabia with the help of a structured questionnaire distributed through LinkedIn. Partial least square (PLS)-based structural equation modeling (SEM) using SmartPLS 4.0 has been performed to calibrate the auxiliary and structural models.FindingsBased on the empirical analysis, IC significantly and directly enhances the competitive advantages of SMEs. Additionally, innovative capability has been found to be a complementary partial mediating condition in enabling IC to foster competitiveness in SMEs. Furthermore, the moderated mediation analysis reveals that innovation capabilities strongly mediate the association between IC and competitiveness in SMEs, characterizing higher entrepreneurial orientation.Research limitations/implicationsThe study provides significant insights to academicians and practitioners seeking to comprehend or configure interactions among IC, innovation capabilities, and entrepreneurial orientation in maturing competitiveness among SMEs, especially in emerging economies. Furthermore, the study provides a valuable integrative perspective on SMEs' competitiveness by involving three voguish constituents of contemporary scholarly discourse grounded into the leading underpinning theoretical perspectives, such as IC theory, RBV, and entrepreneurship theory.Originality/valueThe uniqueness of this model lies in its rich theory-laden conceptualization and explanation that could extend theoretical debate and managerial action to the next levels.

BACKGROUND: Colorectal cancer (CRC) incidence and related mortalities have been steadily increasing in KSA over the past 20 years. CRC in the Kingdom of Saudi Arabia (KSA) population presents in younger ages and in more advanced disease states as compared to other countries. This study was aimed to determine factors (demographic, habitual, environmental, nutritional, and genetic) associated with CRC in Riyadh, KSA. MATERIALS AND METHODS: A matched case-control study conducted in the major hospitals in Riyadh (King Khalid university Hospital, King Faisal Specialist Hospital, Riyadh Military Hospital, Security Force Hospital, King Fahd Medical City). Here most of CRC cases are managed. The cases (n = 121) group included all recently diagnosed and pathologically confirmed Saudi cases of CRC identified during the period 1(st) of January 2017 till 31(st) of December 2018 who agreed to participate and fulfilled the inclusion criteria. A similar number of controls attending the study settings were selected consecutively from the clinics where cases were managed and matched on a 1:1 basis with cases based on age (+/-3 years) and gender. Data were collected using a structured questionnaire. Conditional logistic regression models were fitted to determine factors associated with risk of CRC. RESULT: This study included similar number of males and females in both groups: males 69 (57%) and females 52 (43%) in each group (Chi-square test P = 1.0). The mean (S.D) age in the cases group was 53.6 (S.D = 12.9) and 53.3 (S.D = 12.9) in the controls group (Student test P = 0.86). In the final multivariate conditional logistic regression model, variables independently associated with risk of colorectal cancer were body mass index (OR = 0.93; 95% CI 0.87–0.98; P = 0.011) employment status (inverse relation: OR = 0.33; 95% CI 0.14–0.77; P = 0.010), colon polyps (OR = 4.09; 95% CI 1.06–15.82; P = 0.041), and constipation (OR = 4.98; 95% CI 1.91–15.99; P = 0.001). CONCLUSION: Factors associated with CRC in the major referral hospitals ...
