In this study we tested whether a final irrigation step with saline solution or 80% ethanol improved root canal sealabilty by two popular sealers, an epoxy resin (AH Plus) and a hydraulic calcium silicate cement-based product (BioRoot RCS). Root canals in extracted single-rooted human teeth were instrumented and filled with a matched gutta-percha cone and sealer. During instrumentation and prior to root filling, sealer-specific irrigation protocols were applied. These involved a combined sodium hypochlorite/1-hydroxyethylidene-1,1-diphosphonic acid application, which was followed by irrigation with ethylenediaminetetraacetic acid (EDTA) for AH Plus. Protocols were followed by a 5-ml ultimate rinse with saline solution or 80% ethanol. No such final rinse was the control (N = 9). Canals were then dried with matched paper points. One week after root filling and storage of the teeth at 37°C in a humid environment, Rhodamine B was used to trace leakage. Two-way ANOVA revealed that the type of sealer had a significant (P < 0.05) impact on apical dye penetration while the final rinse did not (P > 0.05). AH Plus provided the slightly better seal (P < 0.05). Leakage occurred between the sealer and the dentin with AH Plus, and between the sealer-to-dentin as well as the sealer-to-gutta-percha interface with BioRoot RCS. In summary and under current conditions, there was no benefit from applying saline or ethanol as an ultimate rinsing solution prior to drying the canal with matched paper points.","PeriodicalId":38153,"journal":{"name":"Swiss dental journal","volume":"134 4","pages":"1-13"},"PeriodicalIF":0.0,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142297534","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}

With its ability to simultaneously visualize soft and hard tissues, MRI has the potential to become an innovative method for accurate diagnosis and planning of dental implants. Dental MRI is already a valuable and useful complement to conventional X-ray imaging techniques and could further minimize the risks of surgery by optimizing existing treatment protocols. Considering current efforts in dentistry to reduce radiation exposure and take a further step toward personalized oral diagnostics that consider patient-specific factors, this article reviews the capabilities of dentomaxillofacial MR imaging in implant surgery. It highlights the various applications of MRI in dental implant surgery and evaluates both the benefits and the clinical challenges. Overall, considering the specific indications and limitations of MR sequences, dental MRI represents a further significant advance in individualized treatment planning in dentistry. It allows consideration of parameters not visualized by conventional imaging techniques and is particularly useful for evaluating surgically relevant parameters, especially those related to soft tissue.","PeriodicalId":38153,"journal":{"name":"Swiss dental journal","volume":"134 3","pages":"100-112"},"PeriodicalIF":0.0,"publicationDate":"2024-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141976901","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}

Tooth loss, regarded as an organ failure, is a core dispute in our profession, as it more often than not does not happen spon-taneously but is influenced by the dentist's treatment plan. Despite the prosthetic possibili-ties of tooth replacement, efforts should be made to preserve as many teeth as possible. Decisions between tooth preservation and extraction are complex and have far-reaching consequences. This article discusses this problem using a clinical case study of a 43-year-old female patient with pronounced localized periodontitis. After a comprehensive diagnosis and treatment planning, a daring regenerative therapy was carried out to try to preserve the tooth. The case shows that even seemingly hopeless teeth can be successfully treated syn-chronously using modern therapeutic approaches. Initial literature data supports the possi-bility of preserving severely compromised teeth in the long term in compliant patients. An integrative treatment approach based on individual patient factors and modern regenerative techniques may well be a viable alternative to tooth extraction and prosthetic restoration, albeit not inexpensive and uncomplicated. This communication emphasizes the need for precise diagnostics, a comprehensive treatment plan, and honest communication with pa-tients about the prospects of success and possible risks, and highlights the strengths of con-sistent tooth preservation.","PeriodicalId":38153,"journal":{"name":"Swiss dental journal","volume":"134 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141898499","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}

Instrumental texture analysis was uti-lized to assess the consistency and compressive strength of AU and GC during a 7-min chewing period. Subsequently, stimulated salivary flow rate (sSFR) was evaluated in healthy subjects using AU and GC over a 7-minute period. The compressive strengths from the pre-liminary test were compared over time with the sialometry data. Eighty-one test subjects, comprising 33 men and 48 women, participated. Over the 7-min measurement period, dif-ferences were observed in the total amount of saliva accumulated per minute. Direct com-parison of AU and GC revealed that regardless of age and gender, the amount of saliva formed after 1 min was 0.63 times less with AU than with GC (95% CI: 0.56 - 0.70; P < 0.001). The accumulated saliva volume with AU was also significantly lower than that with GC in the first 4 min (P = 0.016). However, from minute 5 onwards, the two products no longer showed statistical differences in the total amount of saliva. Comparison of the com-pressive strength of AU and GC showed that the values after 1 and 2 min were significantly higher for AU than for GC (P < 0.05); for all other time points, the compressive strength was higher for GC. In the mixed-effects model after log-transformation of compressive strength and saliva volume, GC exhibited decreasing saliva volumes with increasing compressive strength (P <0.001). Conversely, the opposite was observed for AU (P = 0.019). The study suggests that the consistency or compressive strength of paraffin wax chewing gums from different manufacturers could impact sSFR.","PeriodicalId":38153,"journal":{"name":"Swiss dental journal","volume":"134 3","pages":"18-34"},"PeriodicalIF":0.0,"publicationDate":"2024-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141306951","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}
