There is scant scientific data about the biocompatibility of root canal filling materials of various chemistry on the periapical area. This study aimed to investigate the effects of different root canal sealers and their eluates on human alveolar osteoblasts in terms of cell proliferation, adhesion, morphology and gene expression in vitro. Five endodontic sealers (AH Plus®, Apexit®, Tubli-Seal®, Real Seal SE®, EndoRez®) and one gutta-percha obturation material (BeeFill®) were tested. Human alveolar osteoblasts derived from 3 different donors following incubation with sealer eluates after 24 h and 72 h were investigated by means of qPCR (gene expression). Morphological reactions of the alveolar osteoblasts were measured by culturing the cells for 3 d, and 7 d and 14 d, respectively, followed by scanning electron microscopy (morphology, adhesion) and fluorescence imaging of the actin cytoskeleton (morphology, proliferation). A repeated measures analysis was performed and p-values were adjusted by Tukey. While all sealers influenced the cell morphology and the expression of genes associated with apoptosis (Casp3), proliferation (histone H3), and inflammation (interleukin-6 and matrix metalloproteinases 1 and 3), mainly AH Plus® and Apexit® yielded a regular actin cytoskeleton and beneficial gene expression patterns. Regarding cell adhesion, only AH Plus® supported proper anchorage for alveolar osteoblasts. Our results provide evidence for the biocompatibility of epoxy resin-based endodontic sealers, i.e. AH Plus®, while other sealers proved cytotoxic for alveolar osteoblasts. Further studies are needed for understanding the bone cell reactions after endodontic treatment and the clinical decision-making regarding the sealer of choice for root canal fillings.","PeriodicalId":38153,"journal":{"name":"Swiss dental journal","volume":"132 9","pages":"586-597"},"PeriodicalIF":0.0,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141200985","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Twenty extracted human maxillary premolars were randomly divided into 2 groups according to the dentin sealing technique (n=10). A standardized mesio-occlusal-distal cavity was prepared with reduction of the palatal cusp. The dentin surfaces of the IDS group were immediately sealed after finishing the preparation (before taking impressions, temporization, and 14-day storage at 37°C) using a bonding system (ALL-BOND 3®, ALL-BOND 3® RESIN) and flowable composite (Te-Econom Flow). Impressions were made and temporary restorations were fabricated using PRO-V FILL®. The wax patterns were milled and the onlays were fabricated by heat-pressing technique (IPS e.max Press). After bonding the final restorations with resin cement (Variolink N), the specimens were thermocycled. Fracture strength was measured using a universal testing machine (Testometric M350-10KN) at 1 mm/min until failure occurred. Student's t-test was used to evaluate the results of the fracture strength test. The failure mode was examined using a stereomicroscope. The mean fracture strength in the IDS group (1335 ± 335 N) was statistically significantly higher than that for the DDS group (931 ± 274 N) (p < 0.05). Fracture of the restoration with a small portion of the tooth was the most frequent mode of failure. Within the limitation of this in vitro study, there was an improvement in the fracture strength of ceramic onlays with the use of IDS. However, the ceramic onlays were strong enough to withstand the physiological mastication force in both groups.","PeriodicalId":38153,"journal":{"name":"Swiss dental journal","volume":"132 7-8","pages":"482-489"},"PeriodicalIF":0.0,"publicationDate":"2022-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141201013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Assessment of blood in saliva may improve diagnostics, serve as an outcome measure in clinical trials and support patient education through point-of-care tests. This work analyzed salivary heme using a rapid test format and separately using a lateral flow immunoassay assay [LF] for chair-side implementation. Clinical examinations stratified adult subjects into healthy, gingivitis or periodontitis groups at baseline. Healthy subjects presented no periodontal pockets and whole mouth gingivitis scores of less than 1.0. Gingivitis subjects registered gingival index scores greater than 1.0. Included in the periodontal disease group were subjects with periodontal pockets greater than 4 mm. The rapid test is based on the peroxidase activity salivary heme converting a colourless probe to a coloured compound for spectrophotometric analysis. For the LF assay, saliva was placed in the test window of the device with reactions scored after room temperature incubation. Average salivary heme concentrations in the healthy, gingivitis and periodontal disease groups were 27, 201 and 326 nM respectively, by the rapid test, representing significant differences by analysis of variance and Tukey's-multiple comparison tests (p<0.05). Similarly, results in the LF assay demonstrated increasing band intensity from the healthy to the periodontal disease groups and was quantifiable by image analysis. This pilot study emphasizes the potential efficacy of rapid heme measurement in investigations of oral health.","PeriodicalId":38153,"journal":{"name":"Swiss dental journal","volume":"132 7-8","pages":"490-497"},"PeriodicalIF":0.0,"publicationDate":"2022-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141200946","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the aim of this study was to evaluate the impact of a single information session with OHI on both the knowledge about the consequences of lacking oral hygiene and the likelihood of implementing these instructions in unaccompanied adolescent asylum seekers living in Switzerland. Before and after a single information session with OHI, adolescent asylum seekers in two asylum centres (Menziken and Suhr, AG) were surveyed with written questionnaires. During the event, the consequences of lacking oral hygiene on oral health were explained and the Bass brushing technique was instructed and practised. The present analysis included 30 male asylum seekers aged 15-18. In total, 90% (n=27) cleaned their teeth daily and 70% (n=13) had received previous OHI at their school (19.1%) or a doctor's office (9.5%) in their country of origin or in Switzerland (19.1%), respectively. Following the event, 90% (n=27) stated they had learned something new and 93.3% (n=28) wanted to implement the instructions in their daily routine. While 63.3% (n=19) of the respondents knew the consequences of lacking oral hygiene on oral health before the event, this value increased to 96.7% (n=29) reaching statistical significance (p=0.0039). In conclusion, the results of the present study suggest that the implementation of a single information session with OHI in asylum centres may improve the level of knowledge in adolescent asylum seekers and their oral health.","PeriodicalId":38153,"journal":{"name":"Swiss dental journal","volume":"132 ","pages":"404-413"},"PeriodicalIF":0.0,"publicationDate":"2022-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141200994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
