Methods: A total number of 160 samples were prepared using four types of resin-based materials\u2014Group A (n = 40): flowable composite, Group B (n = 40): heavy-flow composite, Group C (n = 40): resin-based sealant and Group D (n = 40): nano-hybrid composite. Then, the samples were distributed into four subgroups according to the submersion solution: a (n = 10): artificial saliva, b (n = 10): coffee, c (n = 10): cola and d (n = 10): red wine. The Vickers microhardness, Young\u2019s modulus of elasticity and scratch resistance were assessed using a CETR UMT-2 tribometer. Results: The obtained results showed that 14-day submersion of the resin-based materials in coffee, cola and red wine solutions significantly (p &lt; 0.05) decreased the microhardness values (VHN), Young\u2019s modulus of elasticity and scratch resistance. Fourteen days of storage in coffee decreased the microhardness values of flow resin from 117.5 to 81.59 VHN (p &lt; 0.001) whereas the values of the nanohybrid resin decreased from 125.5 to 89.4 (p &lt; 0.001). The elasticity modulus of the heavy flow resin showed a decline from 15.57 to 10.50 GPa after 14 days\u2019 submersion in coffee (p &lt; 0.001), and from 21.29 to 13.10 GPa for the nanohybrid resin after immersion in cola (p &lt; 0.001). For the scratch test, the resin-based sealant showed a significant decrease after 14 days of storage in coffee, from 0.34 to 0.02 units. Conclusions: The submersion of conventional nanohybrid, flowable, heavy-flow composite resins and resin-based sealants in coffee, cola and red wine solutions changes the mechanical properties (Young\u2019s modulus of elasticity, Vickers microhardness and scratch resistance). The most resistant resin-based material to acid attack was the conventional nanohybrid composite resin, followed by heavy flow resin, flowable resin and resin-based sealant.<\/jats:p>","DOI":"10.3390\/dj13010004","type":"journal-article","created":{"date-parts":[[2024,12,25]],"date-time":"2024-12-25T19:29:52Z","timestamp":1735154992000},"page":"4","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Evaluation of the Mechanical Properties of Different Dental Resin-Based Materials After Submersion in Acidic Beverages"],"prefix":"10.3390","volume":"13","author":[{"given":"R\u0103zvan Constantin","family":"Br\u00e2nzan","sequence":"first","affiliation":[{"name":"Faculty of Dental Medicine, Grigore T.
