Periodontal status was retrospectively assessed based on the radiographically visible alveolar bone loss (%). Staging and grading of periodontal disease according to the 2017 classification for periodontal disease was performed. Various general and periodontal parame­ters, medications, and diagnoses of systemic diseases in association with periodontal diseases were analyzed as potential risk factors for bone loss. Statistical analysis was performed using Pearson correlations, Wilcoxon rank-sum tests, Kruskal-Wallis tests, and multiple linear regressions (p < 0.05).\r\nResults: Periapical radiographs were available from 199 patients (86 females; age: 41.1 ± 15.0 years). Based on a distance from the cemento-enamel junction to the marginal bone level exceeding 2 mm, 174 (87.4 %) patients were diagnosed with periodontitis (22.4 ± 20.6 % bone loss). Most periodontitis patients were classified as stage I (39.7 %), followed by stage II (29.1 %), stage III (14.1 %), and stage IV (4.5 %). Generalized periodontitis was most frequently observed in stage I patients (p ≤ 0.047). Significant predictors of % bone loss were age (β = 0.65; 95%-CI: 0.40–0.89; p < 0.001), intellectual disability (β = 11.87; 95%-CI: 1.21–22.52; p = 0.029), and smoking/nicotine dependence (β = 17.29; 95%-CI: 3.42–31.16; p = 0.015).\r\nConclusion: Periodontal disease is common in German patients with disabilities.

In half of the groups, sand-blasting, silica coating, and hydrofluoric acid etching was followed by the use of a universal primer. If the universal adhesive was applied in ER, contamination was performed either before or after phosphoric acid etching. If the universal adhesive was applied in SE, bonding was performed after contamination. In the control groups, no contamination was simulated. Shear bond strength (SBS) and failure modes of composite buildups were determined after thermal cycling (10,000 cycles, 5°C-55°C). Statistical analysis was performed using analyses of variance, Weibull statistics, and χ2 tests (p<0.05).\r\nResults: In ER, sandblasting and silica coating significantly reduced SBS (control: enamel =25.7±4.2 MPa; dentin = 22.0±5.3 MPa) only when performed after phosphoric acid etching. Contamination with hydrofluoric acid impaired SBS on enamel but not on dentin. The self-etching ceramic primer reduced SBS, but not significantly.

It was sent to all dental schools in Germany (n = 30). Whenever possible, data were compared to previous studies conducted in 2000 and 2009. Statistical analysis was performed using Fisher's exact tests (p < 0.05).\r\nResults: Twenty-nine schools responded to the survey - a response rate of 97%. All respondents indicated positive experiences with the repair of restorations. The teaching of repairs in 2018 (90%) was found to be comparable to the findings from the 2009 survey (88%, p = 1.000), but significantly increased since the 2000 survey (50%, p = 0.006). Main reasons reported for teaching repairs are tooth substance preservation (97%) and reduction of pulpal damage (79%). Main clinical indications are marginal defects and secondary caries. When performing repairs, almost all dental schools were found to teach both mechanical and adhesive substrate surface conditioning. Marked variation was observed in the method of mechanical surface treatment, with air abrasion having gained widespread popularity. The average expected longevity of repairs was 7.4 ± 3.0 years.\r\nConclusions: The teaching of the repair of resin composite restorations is widespread in dental schools in Germany. Aspects of this teaching were found to be more consistent between dental schools than in previous surveys, albeit variation in operative techniques still exists.\r\nClinical significance: Graduates from dental schools in Germany may be found to be well equipped with the knowledge and skills to perform repairs of defective resin based composite restorations in clinical practice."],["dc.identifier.doi","10.1016/j.jdent.2018.06.008"],["dc.identifier.pmid","29933003"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/65689"],["dc.language.iso","en"],["dc.relation.issn","0300-5712"],["dc.relation.orgunit","Poliklinik für Präventive Zahnmedizin, Parodontologie und Kariologie"],["dc.subject.gro","Minimally invasive dentistry"],["dc.subject.gro","Restoration repair"],["dc.subject.gro","Teaching"],["dc.title","Contemporary teaching of restoration repair at dental schools in Germany – Close to universality and consistency"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]
