Various surface treatments and bonding protocols have been proposed to enhance adhesion between denture teeth and denture base; however, reliable bonding between three-dimensional (3D)-printed denture teeth and denture bases remains a challenge, and evidence regarding the influence of bonding strategies and surface treatment protocols is limited.</p><p><strong>Methods: </strong>3D-printed tooth-colored and denture base specimens (n = 72) were fabricated and allocated into 3 bonding agent groups (n = 24); in each group, the tooth-colored specimens were subdivided into two subgroups. In subgroup A, the undersurface of the tooth-colored specimens was air-abraded, while in subgroup B, it remained untreated. The bonding agent in the first group was 3D printing denture base liquid resin; in the second group, a universal adhesive; and in the third group, a resin cement. All the specimens were subjected to thermocycling for 5000 cycles, after which shear bond strength was evaluated using a universal testing machine. The mode of failure was evaluated under a stereomicroscope. Two-way analysis of variance was used to assess the effect of the bonding agents, surface treatment, and their interactions. Pairwise comparisons were performed utilizing pairwise t-tests with Bonferroni correction. Failure mode distributions were evaluated using the Fisher's exact test.</p><p><strong>Results: </strong>The null hypothesis was partially rejected. Two-way ANOVA revealed significant main effects of bonding agent (P < 0.001); neither surface treatment (P = 0.881) nor the bonding agent-surface treatment interaction (P = 0.146) reached statistical significance. The highest shear bond strength was reported in the liquid resin subgroups 9.04 ± 2.27 and 8.39 ± 2.12, and the lowest shear bond strength was in the resin cement subgroups 5.12 ± 1.75 and 4.27 ± 1.46. Airborne-particle abrasion had no significant effect within any individual bonding agent (P = 0.438, P = 0.130, P = 0.315, respectively).

This substudy evaluates if Dental PCC@Home will promote oral health, participation, and self-determination among older adults living with complex care needs.</p><p><strong>Methods: </strong>Dental PCC@Home is embedded within the parent GAPA cluster randomised controlled trial. Decisions about dental care are guided by a patient decision aid and discussion of needs expressed by the older adult or identified by care staff. Participation in the substudy is voluntary. Eligible intervention-group participants are offered a patient decision aid to support decisions about whether and how to receive dental care, followed by one of four pathways: online dental consultation, mobile home dental care, a dental clinic visit, or declining dental care. Eligible control-group participants receive standard care. Oral health and quality-of-life assessments are conducted at baseline and at six and twelve months; cognitive function is assessed at baseline only. Co-primary outcomes are changes in oral health status (ROAG) and oral health-related quality of life (GOHAI) from baseline to twelve months. General health-related quality of life (EQ-5D-5 L) is a secondary outcome. Quantitative analyses will account for clustering and repeated measurements. Semi-structured interviews with older adults, significant others, and care staff will explore experiences of care, decision-making, and implementation and will be analysed using qualitative content analysis.</p><p><strong>Discussion: </strong>This project will generate evidence on a new cross-organisational model designed to improve access to oral health care for frail older adults living at home. By integrating dental care into existing care processes and offering flexible care pathways, the model has the potential to strengthen autonomy, reduce inequalities, promote health and, when indicated, address oral diseases earlier in home care. The findings may inform future practice, policy development, and person-centred approaches to oral health in ageing populations.</p><p><strong>Trial registration: </strong>ClinicalTrials.gov NCT06310798.
