The present study aims to determine the impact of toothpaste abrasiveness (REA-value) and brushing force on enamel wear after erosion. 140 enamel samples from bovine teeth were divided into seven groups (N = 20). Each group was assigned a different toothpaste with varying levels of abrasiveness (groups 1+2: Candida Parodin (REA 2), groups 3+4: Candida Multicare (REA 9), and groups 5+6: Candida White Micro Crystals (REA 19)). The samples were first exposed to a citric acid solution (pH 2.60; 2 min) to simulate an erosive attack and then subjected to brushing with the assigned toothpaste using an automatic brushing machine at 1- and 2-N brushing force. Samples of group 7 were left unbrushed and served as the control group. The erosive/abrasive cycling was repeated 10 times. Enamel wear was measured profilometrically. Higher erosive/abrasive wear was observed in all toothpaste groups compared to the control. In all toothpaste groups, erosive/abrasive wear was significantly higher at 2-N brushing force than 1 N (P < 0.05). At 1-N and 2-N force, Candida Parodin showed lower enamel wear than Candida Multicare and Candida White Micro Crystals. The results showed that toothpastes with higher REA values result in greater abrasion of eroded enamel, but only up to a certain value. Eroded tooth structure is more prone to abrasion at higher contact pressure, but REA value has a greater influence. Patients with erosion should use toothpaste with low REA value and avoid excessive contact pressure.","PeriodicalId":38153,"journal":{"name":"Swiss dental journal","volume":"135 2","pages":"27-36"},"PeriodicalIF":0.0,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144020322","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 total of 18.5% had an underlying medical condition and 84.0% had a migration background. Children of migrant parents had significantly lower German proficiency than those of Swiss nationals (p < 0.05). Lower household incomes were predominantly observed in families with a migration background. Parental awareness of oral health varied with 58.8% unaware of whether their child's toothpaste contained fluoride. Children of Swiss parents were more likely to begin brushing their teeth at 6-8 months, whereas children with a migration background tended to start later (p < 0.05). High sugar consumption was prevalent, with 40.7% of children consuming sweets daily. Dental anxiety was reported in 60.7% of children, particularly in older age groups (p < 0.05).

They are frequently missed due to their asymptomatic progression. Three-dimensional imaging and increased awareness within the dental community have likely contributed to the observed rise in ECR prevalence over the recent years. While the exact etiology of ECR remains unclear, numerous risk factors have been identified, encompassing both physical and chemical factors. However, idiopathic cases have also been documented. Literature highlights the propensity of ECRs to occur in anterior teeth and molars, often linked to prior orthodontic treatments and picked up by bitewing or periapical radiographs. However, in cases involving canines, early diagnosis is frequently missed, and lesions are typically discovered at a later stage only, when clinical signs and symptoms manifest. We present several cases in this narrative review, including a case report on a 59-year-old patient presenting with an ECR in the maxillary left canine (tooth 23), decades after orthodontic treatment. The lesion was successfully managed using a combination of endodontic and surgical treatment. Despite the advanced stage of resorption, the tooth was preserved. Given ECR's slow progression and frequent late clinical detection, additional radiographic monitoring of front and canine teeth can be recommended for patients with predisposing factors, such as a history of orthodontic treatment or trauma. This proactive approach can facilitate earlier diagnosis and timely intervention, improving outcomes for affected teeth.","PeriodicalId":38153,"journal":{"name":"Swiss dental journal","volume":"135 1","pages":"175-187"},"PeriodicalIF":0.0,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143659135","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}

This study aims to review and evaluate the available evidence specifically on the survival and success rates of immature autotransplanted third molars and to identify prognostic factors that influence these outcomes. A comprehensive search was conducted in the Elsevier Journals (ScienceDirect), MEDLINE (PubMed), and Dentistry & Oral Sciences Source (EBSCOhost) databases up to May 2024. Risk of bias within studies was asse ssed with the CASP guidelines. Nine studies met the inclusion criteria for qualitative and quantitative analysis. The pooled survival rate was consistently high across studies, estimated at 91.867% (95% CI: 85.058% to 96.741%), while the success rate, though slightly lower, remained substantial at 90.162% (95% CI: 79.813% to 97.067%). Key prognostic factors identified include the developmental stage of the donor teeth (Moorrees stages from R ¼ to Rc), showing enhanced success due to better potential for pulp revascularization and continued root growth. Additionally, innovative techniques, including advanced methods like computer-aided rapid prototyping (CARP) and platelet-rich plasma (PRP), were found to positively impact healing and integration. Fixation methods also played a role, as excessive rigid fixation was linked to higher rates of ankylosis and inflammatory root resorption. Future research should prioritize recipient site and donor tooth characteristics, standardized success criteria, extended follow-up periods, and refined treatment protocols to enhance predictability and long-term outcomes in teeth autotransplantation.","PeriodicalId":38153,"journal":{"name":"Swiss dental journal","volume":"135 1","pages":"145-174"},"PeriodicalIF":0.0,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143606561","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}

It included the PubMed, Livivo, Directory of Open Access Journals, and ScienceDirect databases, the Cochrane Central Register of Controlled Trials, ClinicalTrials.gov and the International Clinical Trials Registry Platform, as well as grey literature databases and ResearchGate, further supplemented by the references of the included study articles. In accordance with the predefined inclusion and exclusion criteria, a total of 92 experimental study articles were included in the review, focusing the optical, mechanical, chemical, and biological material properties, but also regarding the surface characteristics and the interface between the restoration and the tooth structure. Given the considerable heterogeneity and in vitro design of the included study articles, it can be demonstrated that Coca-Cola has an effect on the materials under consideration. However, the extent of this influence is highly dependent on the specific restorative materials and the methodology used. The determining factors are accumulated contact time and frequency of exposure, and these factors therefore serve as a critical starting point for preventive measures.","PeriodicalId":38153,"journal":{"name":"Swiss dental journal","volume":"135 1","pages":"38-128"},"PeriodicalIF":0.0,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143013322","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}
