Composite resins, particularly nanofilled composites, are widely used due to their superior mechanical and aesthetic properties. Accurate tooth color selection is crucial, and methods include visual (shade guides) and instrumental (spectrophotometers, colorimeters, and intraoral scanners). Newer biomimetic composites, such as Admira Fusion 5 and Clearfil Majesty ES-2 Universal, simplify shade selection through advanced optical technologies. A randomized clinical study involving 30 patients compared the color-matching accuracy of two biomimetic composite resins: Admira Fusion 5 (Voco) and Clearfil Majesty ES-2 Universal (Kuraray). The study utilized the Vita Easyshade spectrophotometer and the Primescan intraoral scanner. Patients were treated following standardized protocols, and shade accuracy was evaluated pre- and post-restoration using Cohen\u2019s Kappa index. Admira Fusion 5 showed higher shade-matching accuracy, with good agreement between pre- and post-restoration measurements using both instruments. Clearfil Majesty ES-2 Universal demonstrated lower reproducibility in shade matching, particularly in posterior teeth, with lower agreement in pre- and post-tests. Instrumentation Comparison: Primescan showed slightly better performance than Easyshade, but both provided comparable results. In conclusions, universal composites may not always achieve optimal shade matching in posterior teeth. Layered composites provide better color adaptability. While digital instruments enhance shade accuracy, combining them with visual methods yields the best clinical outcomes. Further research with larger sample sizes is needed to improve shade-matching techniques in aesthetic restorative dentistry.<\/jats:p>","DOI":"10.3390\/ma18122800","type":"journal-article","created":{"date-parts":[[2025,6,16]],"date-time":"2025-06-16T05:28:33Z","timestamp":1750051713000},"page":"2800","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Pilot Study of the Shade Matching of Biomimetic Composite Resins in Posterior Dental Restorations: Randomised Clinical Trial"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8333-4924","authenticated-orcid":false,"given":"Cristina","family":"Rico-Romano","sequence":"first","affiliation":[{"name":"Faculty of Dentistry, Alfonso X El Sabio University, 28691 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dina Aslimani","family":"Amar","sequence":"additional","affiliation":[{"name":"Faculty of Dentistry, Alfonso X El Sabio University, 28691 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Valentin","family":"Ducept","sequence":"additional","affiliation":[{"name":"Faculty of Dentistry, Alfonso X El Sabio University, 28691 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-7500-9072","authenticated-orcid":false,"given":"Rosa M.","family":"Vilari\u00f1o-Rodr\u00edguez","sequence":"additional","affiliation":[{"name":"Faculty of Dentistry, Alfonso X El Sabio University, 28691 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5066-3935","authenticated-orcid":false,"given":"Pablo","family":"Garrido-Mart\u00ednez","sequence":"additional","affiliation":[{"name":"Faculty of Dentistry, Alfonso X El Sabio University, 28691 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vanessa","family":"Gutierrez-Vargas","sequence":"additional","affiliation":[{"name":"Faculty of Dentistry, Alfonso X El Sabio University, 28691 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0533-9065","authenticated-orcid":false,"given":"Jes\u00fas","family":"Mena-\u00c1lvarez","sequence":"additional","affiliation":[{"name":"Faculty of Dentistry, Alfonso X El Sabio University, 28691 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,6,14]]},"reference":[{"key":"ref_1","first-page":"215","article-title":"Composite resins: Review of materials and clinical indications","volume":"11","year":"2006","journal-title":"Med.
