Knowledge and Attitudes of Undergraduate Dental Students Toward Conventional and Digital Workflows in Maxillofacial Prosthetics: A Cross-Sectional Survey

Background: Digital technologies are increasingly transforming the field of maxillofacial prosthetics; however, the extent to which undergraduate dental education has adapted to these developments remains unclear. Evaluating dental students’ knowledge and attitudes toward conventional and digital workflows is essential for identifying potential educational gaps.Methods: A cross-sectional questionnaire-based survey was conducted among 201 undergraduate dental students (99 fourth-year and 102 fifth-year) receiving clinical prosthodontic training. Data were collected using a 24-item structured questionnaire distributed online. Knowledge and attitudes were assessed using a 12-item Likert-type scale. Descriptive statistics were calculated, and comparisons between groups were performed using the Mann–Whitney U test and Chi-square test, where appropriate (α = 0.05).Results: Fourth-year students demonstrated significantly higher total knowledge and attitude scores than fifth-year students (p = 0.012). They also reported greater clinical exposure to maxillofacial cases and higher involvement in impression procedures (p = 0.018 and p = 0.036). Conversely, fifth-year students showed significantly higher self-reported knowledge regarding the operating principles of digital scanners (p = 0.002). Fourth-year students expressed stronger confidence in the accuracy and time-saving advantages of digital technologies (p < 0.001 and p = 0.001). Despite positive attitudes toward digitalization, awareness of specialized digital software such as craniofacial CAD and digital imaging platforms remained low among both groups.Conclusions: Although dental students demonstrate positive attitudes toward digital technologies in maxillofacial prosthetics, gaps remain between theoretical awareness and practical knowledge. Integrating structured digital workflow training into undergraduate dental curricula may help improve clinical competence and better prepare future clinicians for digitally driven maxillofacial rehabilitation.Keywords: Maxillofacial prosthetics, digital dentistry, dental education, dental students, digital workflow

In vitro evaluation of aligner attachment bond strength on enamel, composite, and lithium disilicate surfaces using different resin composites

The aim of this study was to evaluate the shear bond strength (SBS) of aligner attachments bonded to enamel, composite-restored, and lithium disilicate glass-ceramic surfaces using flowable and high-viscosity resin composites. Ninety extracted premolars were divided into three groups (n = 30) according to surface type: enamel (Group 1), composite resin restoration (Group 2), and lithium disilicate glass-ceramic (Group 3). Groups 1 and 2 were etched with 37% phosphoric acid, while Group 3 was etched with 9.6% hydrofluoric acid. A universal adhesive was applied to all specimens. Each group was divided into two subgroups based on composite type (flowable or high-viscosity universal; n = 15). SBS and adhesive remnant index (ARI) were evaluated. One-way ANOVA, Student’s t-test, and Fisher Freeman Halton test were used for statistical analyses (p < 0.05). The highest SBS were obtained in Group 1 bonded with high-viscosity universal composite attachments (mean (± SD), 19.6 (± 6.7 MPa)), and the lowest were obtained in Group 2 bonded with flowable composite attachments (mean (± SD), 7.3 (± 1.8 MPa)). Comparison of three groups within themselves according to the composite resin factor, the mean SBS of Group 2 for high-viscosity universal resin was higher than for flowable resin (p < 0.001). ARI scores did not show a significant correlation with either tooth surface or composite resin type. High-viscosity resin composite provides more reliable bond strength than flowable composite when bonding aligner attachments to composite-restored surfaces. Both composite types demonstrated clinically acceptable bond strength on enamel and lithium disilicate surfaces.
