Eight CRs of three sizes were tested: Large (6.5 mm diameter, 1.5 mm thickness), Medium (2.0 mm diameter, 1.5 mm thickness), and Small (1.5 mm diameter, 0.5 mm thickness). Cytotoxicity was assessed by cell counting on immortalized and primary PDL cell lines. CRs containing Surface pre-reacted glass ionomer filler showed significant size-dependent cytotoxicity, with larger specimens exhibiting higher ion release of BO33-, Sr2+, SiO32-, and F-, which correlated with adverse effects. Smaller specimens with reduced ion release had lower cytotoxicity and sometimes promoted cell proliferation. These results emphasize the role of material composition and ion release in the biocompatibility of CR for subgingival restorations. Optimizing specimen size and controlling ion release could mitigate adverse effects, suggesting further research to balance therapeutic benefits and risks in periodontal tissues.","PeriodicalId":11065,"journal":{"name":"Dental materials journal","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144575019","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}

Tooth-brushing abrasion tests were conducted to investigate the durability of the agents. Computer-aided design/computer-aided manufacturing (CAD-CAM) composite-resin blocks were used, and the surface was polished with #2000 SiC paper before the agent application. Four different shade agents were applied to the blocks, treated the surface no/with sandblasting. Tooth-brush abrasion tests were carried out for 20,000 cycles at a frequency of 2 Hz with 2.0 N of brushing force. Surface roughness, gloss, contact angle, and color differences were obtained. The number of repetitions was set to ten. It was found that a significant increase in surface roughness and decreases in gloss and water contact angle by tooth brushing tests were clarified. However, the color change by brushing was not significantly large. The color difference before and after applying agents and surface roughness differed in the shade differences in the agents.","PeriodicalId":11065,"journal":{"name":"Dental materials journal","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144575018","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}

AsAP-loaded PLGA/PCL (50:50) MSs (AsAP-MSs) were prepared using a water-in-oil-in-water emulsion evaporation. β-GP-loaded PLGA/PCL MSs (β-GP-MS) were prepared similarly while β-GP was directly added in oil. The oil phase dichloromethane was evaporated producing pores in MSs. MSs were characterized by physical techniques such as Fourier transform infrared spectroscopy (FTIR). The drug encapsulation efficiency (E.E.) was evaluated by spectrophotometer after water-extracting. The drug releases into supernatant were analyzed after incubating in 2-[4-(2-hydroxyethyl)piperazin-1-yl]ethanesulfonic acid (HEPES)-NaCl buffer at 37°C for 36 days. E.E. was 89% for AsAP and 67% for β-GP, and AsAp was released immediately while β-GP was continuously released. OCP was hydrolyzed to hydroxyapatite, affecting β-GP release.

We developed the gelatin particles releasing inorganic phosphate (Pi) ions as a model to change the local Pi ion concentration around OCP in the OCP/gelatin composite materials. Spectroscopic and chemical analyses indicated that Pi ion released around 2 mmol/L from gelatin particles promoted OCP hydrolysis, although excessive Pi ion release up to around 3 mmol/L suppressed the hydrolysis. The formation of tartrate-resistant acid phosphatase (TRAP)-positive multinuclear cells was increased by the OCP hydrolysis promotion via modulately higher Pi release Pi ion release. However, OCP hydrolysis suppression by excessive Pi ion release decreased the formation of TRAP-positive cells. The present study suggests that the chemical environment induced by OCP hydrolysis under a suitable Pi ion concentration could be associated with promoting osteoclast formation.","PeriodicalId":11065,"journal":{"name":"Dental materials journal","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144274400","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}
