This review was registered on the OSF platform (https://doi.org/10.17605/OSF.IO/QC7VU) and followed PRISMA guidelines. Databases included PubMed, SCOPUS, Web of Science, EMBASE, Lilacs, LIVIVO, and gray literature. Eligibility criteria included in vitro studies using human dentin, which assessed bond strength through microtensile tests after applying mussel-inspired primers. Exclusion criteria were studies evaluating bond strength to enamel, animal dentin, and ceramics, those not using the microtensile test, or those conducting immediate evaluation only. The RoBDEMAT tool was used for risk-of-bias analysis. Two independent reviewers screened 5522 articles, and seven were selected. The studies showed a similar risk of bias performance, with insufficient reporting of different parameters, while not presenting significant publication bias. Meta-analysis revealed significantly higher bond strength in specimens treated with mussel-inspired monomers after thermocycling. Across studies, no substantial reduction in heterogeneity was observed using the leave-one-out method. Mussel-inspired monomers incorporated into the dentin adhesive procedure can enhance bond strength, mainly through their catecholic groups, highlighting their potential in adhesive dentistry. However, drawbacks such as oxidative potential and effects on the degree of conversion may limit their widespread application.","PeriodicalId":11983,"journal":{"name":"European Journal of Oral Sciences","volume":"133 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/eos.70011","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143992453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This trend persisted throughout most days of the experiment, with a peak release observed on day 7. Autoclave sterilization had a significant impact on ion release, raising potential concerns regarding the material's biocompatibility.

The aligners were subjected to hydrolysis under various reaction conditions, including different concentrations of sodium hydroxide (NaOH), temperature, reaction time, ethanol-to-water mass ratio, and stirring rate. After the reaction, the organic components were isolated using thin-layer chromatography (TLC) plates, and their structure was characterized by 1H-NMR spectroscopy and mass spectrometry. The degradation product was identified as 4,4′-methylenedianiline (MDA). The optimal reaction conditions for achieving the maximum degradation yield of MDA were determined to be stirring at 300 rpm at 130°C in a solution containing 5 wt% NaOH and a 1:1 mass ratio of ethanol to water for 24 h. This method demonstrates that clear aligners can be effectively recycled through alkaline hydrolysis, supporting global efforts to reduce environmental emissions.","PeriodicalId":11983,"journal":{"name":"European Journal of Oral Sciences","volume":"133 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143988022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each group was further divided into two subgroups: as-manufactured and porcelain-fired specimens. The microstructure was analyzed using x-ray diffraction (XRD) and scanning electron microscopy with energy-dispersive x-ray spectroscopy (SEM/EDX). Ten Co-Cr frameworks per manufacturing technique were fabricated, with marginal and internal discrepancies measured using micro-CT before and after the firing cycles. The results were analyzed by two-way ANOVA and Tukey multiple-comparison tests. The results showed a mixed microstructure of γ-fcc and ε-hcp cobalt-based phases, with porcelain firings increasing ε-Co content, especially in group C. The C specimens exhibited distribution of small pores, while no pores/defects were found in the SLM group. The SLM group, although not at a statistically significant level, showed reduced marginal and internal discrepancy values after firings. In the same behavior pattern, the C group exhibited statistically significantly lower discrepancy values. Ultimately, all subgroups demonstrated clinically acceptable marginal adaptation, but the SLM frameworks exhibited superior marginal and internal fit which remained unaffected by the firing cycles.","PeriodicalId":11983,"journal":{"name":"European Journal of Oral Sciences","volume":"133 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/eos.70009","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143647757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review aims to provide an up-to-date clinical and biological summary of dental black stain of bacterial origin. Black stain is esthetically unwelcome to patients, and clinicians frequently attempt its removal. Dental black plaque has a prevalence rate of 2.4%–20% affecting both genders equally and may appear throughout the lifetime. Most studies investigating the microflora of black stain reveal that Actinomyces spp. are the most abundant species found. Most authors have found a correlation between black stain and a low caries incidence. Interestingly, individuals with black stain demonstrate higher salivary concentrations of iron, sodium, copper, and calcium/phosphate, higher pH, and lower salivary flow. Standard treatment involves repeated professional ultrasonic cleaning. Alternative treatments include photo-dynamic therapy, application of virgin coconut oil, peroxide therapy, lactoferrin, or oral probiotics. Our best interpretation of the causes implicates the involvement of oral bacteria, resulting in the deposition of iron ions in patients with altered salivary composition. The use of any treatments should be balanced against potential damage to the teeth as a result of the therapy.","PeriodicalId":11983,"journal":{"name":"European Journal of Oral Sciences","volume":"133 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143491396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, we established a cell lineage of OLAB suitable for the analyses of protein expression. We used immunohistochemistry to determine protein expression patterns in vivo. OLAB were treated during culture with zoledronate or denosumab and analyzed by immunocytochemistry and western blotting. Collagen 1 was decreased in vivo in patients with MRONJ and in vitro by denosumab. Zoledronate reduced the level of RUNX2 in vitro. However, RANKL was not significantly affected by zoledronate or denosumab. The results of the present study will help us elucidate the cellular mechanisms of MRONJ. Although culture of OLAB with zoledronate and denosumab significantly altered the protein expression patterns, future research is needed to examine the effects of bone scaffolds, biofilms, and additional cell types mimicking in vivo conditions.","PeriodicalId":11983,"journal":{"name":"European Journal of Oral Sciences","volume":"133 2","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/eos.70003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143457393","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
