Materials and\nMethod: Discs (\u00f86 mm x 2 mm) of suprananofilled resin composite (Palfique LX5\/Tokuyama) and\nnanohybrid resin (Empress Direct\/Ivoclar Vivadent) were fabricated. They were divided into groups\n(n=10), and manipulated with different spatulas: non-manipulated (control), metal spatulas (Almore\nMillennium\/ Golgran, Almore #3\/ Quinelato, LM Arte Modella\/ Quinelato), or plastic spatulas (Jon).\nManipulation involved lightly pressing the spatula 50 times against the resin composite on waterproof\npaper. Color was analyzed at three time points: immediately, after finishing and polishing, and after\n24-hour immersion in distilled water, with CIELab* parameters, \u0394Eab, \u0394E00, and \u0394WID. Spatulas\nand resins were submitted to micromorphological and energy-dispersive X-ray spectroscopic (EDS)\nanalysis. Generalized linear models or Kruskal-Wallis and Dunn tests (\u03b1=5%) were applied. Results:\nResin color changed after manipulation with a metal spatula, but there was no significant difference\nin \u0394Eab and \u0394E00 for the resin composites according to the spatula (p&gt;0.05). The suprananofilled resin\nvaried more than the nanohybrid resin over time (p&lt;0.05). Abrasive wear was observed on the spatulas\nafter manipulating the resin composites, with greater wear for the spatulas used with suprananofilled\nresin. EDS showed different spatula and resin composite compositions. Conclusions: Metal spatulas\ninfluenced resin composite color stability, with greater color change for suprananofilled resin. The\nspatulas exhibited abrasive wear, attributable to the difference in hardness between the spatulas and\nthe resin composites.<\/jats:p>","DOI":"10.54589\/aol.37\/3\/270","type":"journal-article","created":{"date-parts":[[2025,3,2]],"date-time":"2025-03-02T16:07:01Z","timestamp":1740931621000},"page":"270-282","source":"Crossref","is-referenced-by-count":0,"title":["Resin composite color change by spatula manipulation, effects on surface and color stability"],"prefix":"10.54589","volume":"37","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-0434-603X","authenticated-orcid":false,"given":"Samara R","family":"dos Santos Franco","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-6286-8783","authenticated-orcid":false,"given":"Jorge E","family":"da Silva Junior","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8226-3100","authenticated-orcid":false,"given":"Waldemir F","family":"Vieira Junior","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2877-6797","authenticated-orcid":false,"given":"Fabiana","family":"Mantovani Gomes Fran\u00e7a","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0078-9895","authenticated-orcid":false,"given":"Cecilia","family":"Pedroso Turssi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5345-5776","authenticated-orcid":false,"given":"Roberta","family":"Tarkany Basting","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"31696","published-online":{"date-parts":[[2024]]},"container-title":["Acta Odontol\u00f3gica Latinoamericana"],"original-title":[],"deposited":{"date-parts":[[2025,3,2]],"date-time":"2025-03-02T16:07:15Z","timestamp":1740931635000},"score":1,"resource":{"primary":{"URL":"https:\/\/actaodontologicalat.com\/wp-content\/uploads\/2025\/02\/aol_2024_37_3_270.pdf"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024]]},"references-count":0,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2024]]}},"URL":"https:\/\/doi.org\/10.54589\/aol.37\/3\/270","relation":{},"ISSN":["1852-4834"],"issn-type":[{"value":"1852-4834","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024]]}}}
