AB  - Objectives: To evaluate the effects of enhanced personal protective equipment (Enhanced_PPE) on student-operator's experience and restorative procedure. Methods: Student-operators (N = 29 Year 3 dental students) performed Class II composite restorations (SimpliShade, Kerr) in typodont upper molars (OneDental) equipped with N95 respirators, full-face shields, disposable headwear and gowns (Enhanced_PPE) or surgical masks, protective glasses/goggles and non-disposable gowns (Standard_PPE) 2 weeks later. Cavity dimensions were measured on cone beam computed tomography images. The quality of composite restorations was assessed using selected FDI criteria and Vickers hardness. A questionnaire assessed the operators' discomfort, anxiety, confidence, ability to perform, and procedure outcome. Data were analyzed using paired t-test and McNemar test (alpha = 0.05). Results: Student-operators experienced greater discomfort and anxiety, reduced confidence and ability to perform, and rated the procedure as less satisfactory with Enhanced_PPE (p < 0.05). Differences in proximal box width were marginally significant (Enhanced_PPE 1.8 ± 0.4 mm, Standard_PPE 1.6 ± 0.3 mm) (p = 0.047). Other cavity dimensions were similar between groups (p > 0.05) as were restorations regarding surface luster, anatomical form, marginal adaptation, proximal contour, and contact (p > 0.05). There were no differences in the hardness of composite restorations (top p = 0.349, bottom p = 0.334). Conclusions: Enhanced_PPE led to student-operator discomfort, anxiety, and reduced confidence, but did not impact the quality of Class II preparation and composite restorations versus Standard_PPE.

AB  - Objectives. To evaluate optical properties (color and translucency) of 'sandwich' restorations of resin-based composites and esthetically unfavorable dentin restoratives. Methods. Cylindrical 'dentin' specimens (8 mm in diameter and 2 mm thick, N = 5/group) were prepared using EverX Posterior (GC), Biodentine (Septodont), experimental hydroxyapatite (HAP) or conventional composites (Gradia Direct Posterior, GC; Filtek Z250 and Filtek Z500, 3M ESPE). Capping 'enamel' layers were prepared using composites (Gradia Direct Posterior, Filtek Z250 or Z550) of Al or A3 shade and the following thickness: 0.6, 1 or 2 mm. Color (Delta E) and translucency parameter (TP) were determined using a spectrophotometer (VITA Easyshade Advance 4.0, VITA Zahnfabrik). Data were statistically analyzed using analysis of variance with Tukey's post-hoc tests (alpha = 0.05). Results. TP was greatly affected by layer thickness, whilst Delta E depended on shade and layer thickness of the capping composite. HAP and Biodentine showed significantly lower TP and higher Delta E (deviation from 'ideal white') than composites (p  lt  0.05). Greater TP was seen in EverX_composite groups than in corresponding control groups of the same shade and thickness. TP of composites combined with Biodentine or HAP was below 2, lower than the corresponding control groups (p  lt  0.05). Within-group differences of Delta E were greatest in HAP_composite groups. EverX_Gradia and EverX_FiltekZ250 combinations showed the most comparable Delta E with the control groups. Significance. A 2 mm thick layer of composite covering dentin restoratives with unfavorable esthetics is recommended for a final 'sandwich' restoration that is esthetically comparable to a conventional, mono-composite control restoration.
