However, evidence regarding the long-term clinical superiority of high-filled injectable composites and Er,Cr:YSGG laser-based cavity preparation remains limited. The present study aimed to compare the 1-year clinical performance of two different surface preparation protocols (Er,Cr:YSGG laser vs. conventional bur preparation with phosphoric acid etching) and two composite resin types (high-filled injectable vs. conventional paste-type) in the restoration of NCCLs. Methods: In this prospective, split-mouth, randomized controlled clinical trial, a total of 168 NCCLs in 27 patients were restored. Lesions were randomly allocated to four groups according to the combination of surface preparation (Er,Cr:YSGG laser or phosphoric acid etching) and high-filled injectable composite (G-\u00e6nial Universal Injectable) or paste-type composite (G-\u00e6nial Anterior). The same universal adhesive system was used in all cases. Clinical evaluations were performed by a blinded examiner at 1 week, 6 months, and 12 months, using the FDI World Dental Federation criteria. Results: At the 1-year follow-up, 25 patients and 150 restorations were available for evaluation, corresponding to a recall rate of 98.22%. High clinical acceptability was observed in all groups with respect to aesthetic, functional, and biological parameters. Retention was 100% in the acid-etched paste-type composite group and ranged from 94.7% to 97.4% in the remaining groups, with no statistically significant differences among groups (p &gt; 0.05). A transient increase in postoperative sensitivity was detected in the laser groups at the 1-week evaluation (p = 0.026); however, sensitivity scores declined to zero in all groups at 6 months and 1 year. Conclusions: High-filled injectable composites demonstrated 1-year clinical performance comparable to that of conventional paste-type composites in the restoration of NCCLs. Er,Cr: YSGG laser-based cavity conditioning produced outcomes similar to conventional phosphoric acid etching with respect to retention, marginal adaptation, and biological compatibility. The early increase in laser-related postoperative sensitivity was transient and did not compromise long-term clinical success. Taken together, the ease of application and favorable clinical performance of injectable composites indicate that these materials constitute a reliable alternative for the restoration of non-carious cervical lesions.<\/jats:p>","DOI":"10.3390\/jfb17020101","type":"journal-article","created":{"date-parts":[[2026,2,19]],"date-time":"2026-02-19T08:51:09Z","timestamp":1771491069000},"page":"101","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["One-Year Clinical Performance of Injectable and Paste-Type Composite Resins in Non-Carious Cervical Lesions Prepared with Er,Cr:YSGG Laser and Acid Etching: A Randomized Clinical Trial"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7494-4704","authenticated-orcid":false,"given":"Alperen","family":"De\u011firmenci","sequence":"first","affiliation":[{"name":"Department of Restorative Dentistry, Faculty of Dentistry, Van Yuzuncu Yil University, Van 65080, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1799-7161","authenticated-orcid":false,"given":"Beyza","family":"\u00dcnalan De\u011firmenci","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics, Faculty of Dentistry, Van Yuzuncu Yil University, Van 65080, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,2,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"103285","DOI":"10.1016\/j.jdent.2020.103285","article-title":"Prevalence of Noncarious Cervical Lesions Among Adults: A Systematic Review","volume":"95","author":"Teixeira","year":"2020","journal-title":"J.
