The present study aims to evaluate the cytotoxicity, physiochemical, optical, and rheological properties of carbon quantum dots (CQDs) impregnated glass ionomer cement (GIC). Surface passivated fluorescent CQDs were synthesized using citric acid via thermal decomposition and blended with GIC. Characterization studies and rheological measurements were made to evaluate their performance. 3D-printed dental implant models cemented with GIC and GIC-CQD were compared to analyze excess cement residues. MTT assay was performed with human dental pulp stem cells (hDPSCs) and statistically analyzed using ANOVA and Tukey\u2019s test. CQDs with a particle dimension of \u223c2 nm were synthesized. The amorphous property of GIC-CQD was confirmed through XRD. The fluorescence properties of GIC-CQD showed three times higher emission intensity than conventional GIC. GIC-CQD attained maturation with a setting time extended by 64 s than GIC. Cement residue of size 2 mm was detected with a UV light excitation at a distance between 5 to 10 cm. Biocompatibility at 0.125 mg ml<jats:sup>\u22121<\/jats:sup> dilution concentrations of GIC-CQD showed viability greater than 80% to hDPSCs. For the first time, we report that CQDs-impregnated GIC is a unique and cost-effective strategy for in-situ detection of excess cement rapidly using a hand-held device. A novel in-situ rapid detection method enables the dentist to identify residual cement of size less than 2 mm during the implantation. Therefore, GIC-CQD would replace conventional GIC and help in the prevention of peri-implant diseases.<\/jats:p>","DOI":"10.1088\/1748-605x\/ad407b","type":"journal-article","created":{"date-parts":[[2024,4,18]],"date-time":"2024-04-18T22:30:08Z","timestamp":1713479408000},"page":"035040","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":9,"title":["Performance evaluation of carbon quantum dots impregnated glass ionomer cement to avoid peri-implant disease"],"prefix":"10.1088","volume":"19","author":[{"given":"Febina","family":"Josephraj","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ashwin","family":"Kumar N","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vidyashree","family":"Nandini V","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sujatha","family":"S","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8895-1091","authenticated-orcid":true,"given":"Varshini","family":"Karthik","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"266","published-online":{"date-parts":[[2024,4,29]]},"reference":[{"key":"bmmad407bbib1","doi-asserted-by":"publisher","first-page":"9","DOI":"10.3390\/mps5010009","article-title":"A systematic review of cementation techniques to minimize cement excess in cement-retained implant restorations","volume":"5","author":"Reda","year":"2022","journal-title":"Methods Protoc."},{"key":"bmmad407bbib2","first-page":"787","article-title":"A 10-year retrospective comparative human study on screw-retained versus cemented dental implant abutments","volume":"33","author":"Sinjari","year":"2019","journal-title":"J.
