    Abstract The aim of this study was to reduce discrepancies between students and instructors in a preclinical dental course by employing structured peer feedback based on a detailed evaluation sheet. In a crossover study of dental students (n = 32), which compared peer feedback using an evaluation sheet (test) with the traditional method (control), participants completed tasks involving cavity and partial crown preparation. The practical tasks were scored numerically on a scale ranging from one (excellent) to six (failure). The amount of feedback provided by the instructor was also recorded. Statistical analysis was conducted using Wilcoxon signed-rank tests (p < 0.05). Regarding cavity preparation, no statistically significant difference was observed (median (25th-75th percentile)) between the grades received by the test (2.00 (1.50-3.00)) and control groups (2.25 (2.00-3.00)). However, the grades pertaining to partial crown preparation exhibited a statistically significant difference between the test (2.25 (2.00-2.50)) and control (2.50 (2.00-3.00)) groups. LimeSurvey and five-finger feedback were used to assess satisfaction with the new method, revealing that most students found the evaluation sheet and peer feedback to be effective. Within the limitations of this study, structured peer feedback using the evaluation sheet positively impacted grades pertaining to partial crown preparation, requiring less instructor feedback.

    Abstract The aim of this in-vitro study is to compare the prophylaxis powder Airflow® Plus to a conventional prophylaxis paste with regards to surface abrasion and roughness on four different restorative materials. A total of 80 samples were fabricated, including 20 of each investigated material. Among those were a nanocomposite (Ceram X Spectra™ ST, Dentsply), a glass ionomer cement (Ketac Fill™, 3M™), a cast metal alloy (Bio Maingold SG®, Heraeus Kulzer) and a ceramic (HeraCeram® Saphir, Heraeus Kulzer). Of each material, all samples were equally divided into two groups. Samples in one group were treated with AirFlow® Plus using the AirFlow® Prophylaxis Master (EMS, Switzerland) (Group AF) and the ones in the other group with Prophy Paste (Cleanic™, Kerr, Austria) (Group CL) on a rubber cup. Applied force amounted to 1.5 N at 2000 rpm. Under controlled reproduceable conditions, a 10-year interval with 4 application per year, a total of 200 seconds, was simulated. Size of each sample amounted to 6 mm in diameter and 2 mm in height. Half side of each sample were treated. While comparing the treated and untreated area of each sample, surface abrasion and roughness were measured using an optical 3D system. Roughness was measured based on the arithmetic roughness average of the surface (Ra) and root mean square of the surface roughness (Rq). The statistical evaluation of the data was carried out using the non-parametric Mann-Whitney-U-test, Wilcoxon-test and the Kruskal-Wallis test for group comparisons. In conclusion, the use of the rubber cup with Prophy Paste caused a significantly higher abrasion on composite, ceramic and gold compared to the AirFlow® Plus powder (p < 0.05). In group AF, the significant highest values for Ra were determined on GIC, followed by composite, gold and then ceramic in intragroup comparison. Ra on GIC was significantly higher in group AF (p < 0.05).

    Abstract Preventing biofilm-related risks such as gingivitis and white spot lesions during orthodontic treatments is very challenging. The cleaning efficiencies of AirFloss Ultra and I-Prox P sulcus brushes were evaluated using an orthodontic phantom model. After attaching brackets onto black-coated maxillary KaVo teeth, a plaque substitute was applied. The evaluated tooth surfaces were divided into two areas. Cleaning was performed with an AirFloss Ultra with two (A-2) or four (A-4) sprays or an I-Prox P for two (I-2) or four (I-4) seconds. Images before and after cleaning were digitally subtracted, and the percentage of fully cleaned surfaces was determined (Adobe Photoshop CS5, ImageJ). Statistical analysis was performed by ANOVA and post hoc tests with Bonferroni correction (SPSS 25, p < 0.05). The mean values of total cleaning efficacy were 26.87% for I-2, 43.73% for I-4, 34.93%, for A-2 and 56.78% for A-4. The efficacy was significantly higher for A-4 than for A-2, I-4, and I-2. There were significant differences between the four groups. Repeated cleaning led to an improved result. Within the study limitations, the AirFloss Ultra with four sprays proved to be more efficient than the sulcus brush I-Prox P for cleaning.
