Adverse effects of ultrasonic instrumentation and air polishing on dental restorations: a systematic review of laboratory studies. J Esthet Restor Dent 2025; https://doi.org/10.1111/jerd.13428 . A systematic review of the literature was conducted, assessing the potential for adverse effects on surface roughness and marginal integrity with use of ultrasonic instrumentation and air polishing on variety of dental restorations. With the aim to guide clinical practice to aid mitigation of adverse effects. Five databases: Cochrane Library, OpenGrey through DANS, PubMed, Scopus, and Web of Science, and supplemental manual searches were used to identify relevant literature. The review adhered to the PRISMA guidelines. Publications were included between 1978 and 2022. Population: dental restorations or restorative biomaterials in vitro. Intervention: ultrasonic instrumentation and/or air polishing. Comparison: no debridement procedure or paste polishing. Outcome: surface roughness and/or marginal quality. Forty-two laboratory studies were included in the final analysis. The studies evaluated data to answer the following research question: In specimens made of or featuring dental restorations or restorative biomaterials, how does the use of ultrasonic instrumentation and/or air polishing, compared with no debridement procedure or paste polishing, affect the surface roughness and/or marginal quality? Data extracted included: author(s) and year, laboratory studies, biomaterials evaluated, specimen quantity, specimen geometry, grouping methodology, types of ultrasonic and/or air polishing devices used, air polishing powders, device operational settings, application type and duration of ultrasonic and/or air polishing, assessments of surface roughness and marginal quality, and the observed effects on both surface roughness and marginal quality. Biomaterial assessed included: porcelain fused to metal (PFM), zirconia (ZrO2), lithium disilicate (LDS), polymer-infiltrated ceramic network material (PICN), fine-structure felspathic ceramic (FSFC), gold alloy, amalgam, resin-modified glass ionomer cements (RMGIC), conventional and flowable resin-based composite (RBC), and silorane-based RBCs restorations. Studies measured surface roughness via contact profilometry, scanning electron microscopy, and atomic force microscopy. Ra was used as a parameter for surface roughness. Stereomicroscopy and confocal laser microscopy were used to assess marginal quality. Risk of bias was assessed using the RoBDEMAT tool. Ultrasonic instrumentation and air polishing both negatively impacted surface roughness. Air polishing with sodium bicarbonate and calcium carbonate powders had a significantly greater effect on surface roughness, compared with erythritol and glycine powders. The surface roughness for RBCs and RMGICs were the most affected by ultrasonic instrumentation.

Influence of glass ionomer-based luting cements on the clinical success of zirconia crowns: randomized clinical trial. Oper Dent 2025; 50: 144–156. This 24-month prospective, split-mouth randomised clinical trial compared the performance of conventional glass ionomer cement (GIC) and resin-modified glass ionomer cement (RMGIC) for luting full-coverage ceramic-fused-to-zirconia crowns. Thirty participants were enrolled; 27 attended the 12-month review and 24 were assessed at the 24-month follow-up. Inclusion criteria included adults who needed two anterior or two posterior crowns. Silicone impressions were used to fabricate casts, which were scanned for CAD/CAM milling of zirconia copings. Clinical outcomes were assessed at 7 days, 12 months, and 24 months by calibrated, blinded examiners. The primary outcome was crown retention; whilst secondary outcomes included fracture, wear, pulpal response, patient satisfaction, plaque and bleeding indices, and marginal integrity. Assessments followed modified USPHS and FDI criteria. An intention-to-treat analysis using last observation carried forward was applied. Fisher’s Exact test compared anterior and posterior outcomes, while Kaplan–Meier estimates and log-rank tests were used to evaluate restoration survival (p < 0.05). Success rates recorded were 93.3% for GIC and 100% for RMGIC. For anterior crowns, GIC success declined to 83.3% at two years, while RMGIC maintained a 100% success rate throughout. Posterior crowns showed 100% success in both groups, with no loss of retention or secondary caries recorded. Both GIC and RMGIC demonstrated favourable short-term outcomes. However, anterior crowns cemented with GIC were more prone to failure, suggesting that crown location should inform cement selection. Optimising luting agent choice may improve long-term clinical success.","PeriodicalId":12234,"journal":{"name":"Evidence-based dentistry","volume":"26 3","pages":"130-131"},"PeriodicalIF":2.3,"publicationDate":"2025-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41432-025-01172-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144247209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Articles were screened based on their investigation of the effect of MSDP on the development of dental conditions in offspring. Methodological quality was assessed using the Newcastle Ottawa Scale (NOS), while the quality of evidence was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach. A total of 17 articles were included in this review, focusing on the primary dental developmental outcomes: molar incisor hypomineralisation (MIH), enamel defects (other than MIH), missing teeth, dental eruption, and short root anomaly. Due to high levels of heterogeneity among the studies, meta-analysis was not performed. The majority of studies demonstrated good methodological quality (n = 10), with three assessed as fair and four as poor. The quality of evidence was categorised, with three outcomes receiving a low quality of evidence classification, and tooth eruption and short root anomaly being classed as very low quality. Statistically significant associations between MSDP and each dental outcome had varied results across studies. Most studies concluded an association between MSDP and conditions such as enamel defects (other than MIH), missing teeth, and short root anomaly. Some studies found associations with MIH, while the majority found no link between MSDP and tooth eruption in offspring. This review suggests a potential association between MSDP and dental development conditions in offspring. However, due to the low quality of evidence and inconsistencies in findings across observational studies, a definitive association cannot be drawn. Further, novel and high-quality research is needed to understand the impact MSDP on dental development in offspring.","PeriodicalId":12234,"journal":{"name":"Evidence-based dentistry","volume":"26 3","pages":"157-157"},"PeriodicalIF":2.3,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41432-025-01168-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144173246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
