RESUMO
AIMS AND OBJECTIVES: The aim of this study was to evaluate the faculty members' attitude toward establishing a business center in the College of Dentistry, King Saud University, Riyadh, Saudi Arabia. MATERIALS AND METHODS: A structured questionnaire comprised three sections: demographic variables such as gender and age, questions regarding the faculty's attitude toward a dental college business center, and a comparison between a business center and private clinics. Statistical analysis was performed to compare the groups with scale response variable; independent t-test, analysis of variance, and factor analysis were also conducted. RESULTS: The study results show that 43 respondents were men and 26 were women. Twenty respondents were ranked in the position of assistant professor, whereas 38 were ranked as associate professors, and 11 as professors. In total, 88.5% of female faculty members supported the idea of establishing a business center at the dental college, whereas 65% of male faculty members supported the same idea. There is a statistically significant difference among them (P < 0.05). The factor analysis extracted three factors named as "treatment accessibility," "treatment effectiveness," and "treatment cost." The factor loading ranges from 0.652 to 0.867, and altogether they explain 79% of the total data variance. CONCLUSION: Our study proved that 65.1% of male and 88.5% of female dental faculty of the college supported the idea of establishing a business center at the dental college as funding is needed to invest in dental education and research programs in order to formulate the next generation of practitioners to serve the population. This study will add to the progress of establishing a business center in dental education and provides the patient with a treatment accessibility and effectiveness in a low-cost budget.
RESUMO
The aim of the study was to evaluate the effect of diode laser as a phototherapy on surface treatment of fiber post and its bond strength to resin core build-up material. In this in-vitro study fifty fiber post of 1 mm tip-diameter and 20 mm length were used. The posts were mounted and randomly divided into 5 groups (n = 10) according to different surface treatment methods i.e. Group 1: Control, Group 2: Application of 37% Phosphoric Acid, Group 3: Treated with 40% H2O2, Group 4: Sandblasted with 50 µm aluminium oxide particles and Group 5: treated with diode laser. In all specimens including control, a cylinder of resin composite around the fiber post was made. All Specimens were mounted in a universal testing machine. Push-out test was performed and bond strengths were calculated. Using analysis of variance (ANOVA) and post hoc Tukey multiple comparisons test, means of push out bond strength were compared among the study groups. The highest bond strength was shown among Sandblasted [50 µm, Aluminium Oxide (Al2O3)] group [139.86] and the lowest push-out bond strength was observed in Control specimens [75.73]. The bond strength values of fiber post treated with Diode laser [100.81] and 40% H2O2 [105.64] were comparable.
