Therefore, the use of removable dental prostheses (RDPs) is expected to decline over time. This study aims to evaluate the expected decrease in the production of RDPs in Swiss dental laboratories over the past decade. From 2012 to 2022, two indicators of prostheses production were examined: the number of dental laboratories (DL) and dental technicians in Switzerland, and the import and sale rates of denture teeth. 85 DL participated in a survey and indicated their perception regarding market trends. Finally, in-depth data collection was conducted in 16 DL in French-speaking Switzerland to gather the production of various types of RDPs over the last ten years. Over the observation period, the number of DL significantly decreased (p<0.05), while the decrease in dental technicians was less pronounced. The overall quantity of prosthetic teeth imported into Switzerland or sold by Curaden AG witnessed a significant decline (p<0.05). Survey findings revealed inconsistent perspectives from the respondents on the profession's development, despite a tendency suggesting a decline in complete prostheses and an increase in partial or hybrid removable prostheses (p<0.01). Except for a decline in the number of chrome-cast partial prosthesis manufactured (p=0.04), no clear trend was observed in the 16 DL. Despite lower import rates of denture teeth and a perceived shift in denture type, the overall production of RDPs seems to remain substantial.","PeriodicalId":38153,"journal":{"name":"Swiss dental journal","volume":"135 1","pages":"1-22"},"PeriodicalIF":0.0,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142972522","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}

Despite the numerous advantages of this radiation-free, non-invasive procedure for soft tissue diagnostics in the head and neck region, its imaging capabilities for hard tissue, such as bones and teeth, have thus far remained limited in comparison to conventional X-ray technology. In recent years, however, technological advances have led to a notable enhancement in the image quality and the range of applications of dental MRI. This article presents a comprehensive review of the current literature on the utilization of dental MRI for dentomaxillofacial conditions. The article focusses on novel MRI protocols that have been specifically developed to address the inherent challenges associated with imaging the head and neck region. It also considers the latest technological advances, including innovative coils and the use of low and high-field MR systems. The practical case studies are from the fields of conservative dentistry, prosthodontics, orthodontics, oral surgery, and maxillofacial surgery, demonstrating the theoretical concepts and emphasizing the clinical advantages of dental MRI. In conclusion, dental MRI can be a valuable complement to and, in certain cases, a true alternative to X-ray-based procedures.","PeriodicalId":38153,"journal":{"name":"Swiss dental journal","volume":"134 4","pages":"116-150"},"PeriodicalIF":0.0,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142839930","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}

Technique evolved and indications clarified since then and since the Swiss consensus guidelines regarding CBCT were published in 2014 and 2015. Therefore, the Swiss association of dentomaxillofacial radiology decided to initiate the process of updating these guidelines by forming a consensus group divided into a core group responsible for the whole process and an approval group responsible for specific clinical matters. The manuscript outlines the revised guidelines in a practical way and is divided along the different specialties and clinical fields of dentistry. In result the guidelines are updated regarding reconstructive dentistry, orthodontics, geriatric dentistry, temporomandibular joint disorders, maxillofacial traumatology, benign and malignant tumors, assessment and detection of dental foci and endodontic infections and apical surgery. Overall, it can be stated that CBCT is utilized more consistently and somewhat broader than ten years ago. Today CBCT is well established and has proven benefits if indicated and analyzed precisely. Therefore, it might very well become more and more standard in dental radiology.","PeriodicalId":38153,"journal":{"name":"Swiss dental journal","volume":"134 4","pages":"86-115"},"PeriodicalIF":0.0,"publicationDate":"2024-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142773313","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}

A systematic search was conducted using all relevant databases up to April 5, 2024. The inclusion criteria were as follows: a) human participants, b) a sample size of at least five autotransplanted teeth, c) molar or premolar transplants, d) English language use, and e) at least 1 year of follow-up. The following parameters were assessed: probing pocket depth, recession, tooth mobility, ankylosis, bone level, and tooth loss. Our search identified 466 records, and after our selection process, 25 articles were suitable for analysis, with a total of 3732 teeth (569 premolars and 350 molars) with a mean follow-up duration of 6.1 years. The 10-year survival rate of autologous tooth transplants ranged from 33.8% to 100%, and the mean complication rates of root resorption and ankylosis were 8.9% (13 studies) and 14.0% (10 studies), respectively. Periodontal complications such as periradicular radiolucency, periodontal defects, and attachment loss occurred in less than 10% of patients. The premolars exhibited superior clinical and radiological outcomes compared with the molars. In conclusion, the survival rate and periodontal status after autologous tooth transplantation (ATT) of premolars and molars were consistent with those of traditional dental implants. Therefore, autotransplantation may be considered in cases where dental implants are indicated. As specific reports on periodontal complications are scarce, further research is warranted to identify the specific factors associated with periodontal complications in autologous transplant recipients.","PeriodicalId":38153,"journal":{"name":"Swiss dental journal","volume":"134 4","pages":"54-71"},"PeriodicalIF":0.0,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142583464","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}

Accurate diagnosis is crucial for identifying the underlying cause and determining appropriate treatment. Diagnostic procedures include clinical examination, ultrasound, fine needle aspiration, biopsy, and imaging techniques. While conventional imaging methods such as X-ray and computed tomography (CT) have proven useful, they exhibit limitations in sensitivity and specificity, especially for soft tissue structures. Magnetic resonance imaging (MRI) provides superior soft tissue contrast, offering additional critical information for differential diagnosis. This article presents a case study of a 29-year-old male with a cervical mass. Advanced dental MRI protocols, including DESS, SPACE-SPAIR, and SPACE-STIR sequences, have significantly enhanced the imaging capabilities of the den-tomaxillofacial region, enabling the generation of high-resolution images of both hard and soft tissues. Especially, MR OPGs have demonstrated the capacity to identify early signs of potential pathology.

They exhibit a wide spectrum of characteristics, ranging from benign, noninvasive lesions to malignant tumors, which collectively present a diagnostic challenge. A 67-year-old patient presented with an incidental finding of induration on the right cheek during dental hygiene. The intraoral examination revealed a soft, non-tender swelling measuring 20 mm in diameter. The sensitivity and percussion tests for the teeth in the fourth quadrant yielded unremarkable results. Panoramic radiography (OPG) revealed tip-ping of the premolars and an unclear apical finding in region 44. Cone-beam computed tomography (CBCT) revealed a sharply defined, lobulated hypodense lesion in the right buccal area. To clarify the diagnosis and optimize perioperative management, a 3 Tesla dental magnetic resonance imaging (MRI) scan was performed. This identified a 23×6×23 mm lipoma along the right mandibular ramus, causing detachment of the buccinator and de-pressor anguli oris muscles. A cinematic rendering reconstruction derived from the MRI data facilitated enhanced visualization for preoperative planning. The surgical excision was performed under local anesthesia, resulting in the successful removal of the neoplasm while preserving the mental nerve and submandibular gland. Histo-pathology confirmed the presence of a lobulated mature cell lipoma. The patient exhibited no complications during the removal of the sutures, with complete wound healing and no recurrence observed.

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}
