The integration of internationalization within higher education has gained attention in both international and local programs, which allows the enrichment of the institutional quality. Previous literature reveals multidimensional considerations to determine the level of internationalization, considered as pre-existing performance indicators, including: (1) ‘Curriculum and academic offerings’; (2) ‘Collaboration and partnership’; (3) ‘Student and academic staff mobility’; (4) ‘Institutional policy’; (5) ‘Resources’; (6) ‘Campus life’; and (7) ‘Performance review and accountability’. This study aimed to investigate the impact of performance indicators of internationalization on academic performance and extracurricular activities among dental students. A validated online self-administered questionnaire was distributed to dental undergraduates. The data from 93 students (response rate: 96.86%) were analyzed using descriptive statistics and simple linear regressions. The findings demonstrated that all performance indicators appeared to have significant impact on self-perceived participations of extracurricular activities (p < 0.05), while only ‘Collaboration and partnership’ (p = 0.016), ‘Student and academic staff mobility’ (p = 0.009), ‘Institutional policy’ (p = 0.008), and ‘Campus life’ (p = 0.005) significantly affected actual participations. None of them appeared to be significant predictors for actual and self-perceived academic performance (p > 0.05). The statistical model constructed in this research can be utilized as a conceptual framework in the future establishment of internationalization among dental schools.

Topical anesthetics are commonly used to minimize pain and anxiety during dental procedures. Research is scarce on the influence of topical anesthetics on bond strength. Thus, this research evaluated the effect of dentin contamination by topical anesthetic solution and gel on the micro-shear bond strengths of etch-and-rinse and self-etch bonding systems. Ninety transversally hemi-sectioned dentin discs were prepared and randomly assigned to three groups: no contamination (control group), contamination with topical anesthetic solution (Xylonor spray, Septodont), and contamination with topical anesthetic gel (Xylonor gel, Septodont). Each contamination group was subdivided into two subgroups (n = 15) based on whether the adhesive system was etch-and-rinse (Optibond Solo Plus, Kerr) or self-etch (Optibond XTR, Kerr). Tygon tubes with resin composite (Filtek Z350 XT, 3M ESPE) were placed on each surface and light cured. After 24 h, a universal testing machine was used to measure micro-shear bond strength (MPa). Furthermore, nine additional specimens of non-contaminated and contaminated dentin were prepared and scanned by a scanning electron microscope. The data of micro-shear bond strength were analyzed using two-way ANOVA, and narrative analysis was used to qualitatively interpret visual data of the micro-morphology of dentin from the scanning electron microscope. No significant differences in micro-shear bond strength among different contamination groups and adhesive systems were found (p > 0.05). The results are supported by micro-morphology of the treated dentin surfaces and modes of failure, as the micro-morphology was similar among contamination and control groups. There was no significant impact of topical anesthetic forms and dentin bonding systems on the micro-shear bond strength, which was supported by the micro-morphology from a scanning electron microscope.
