Surface roughness changes were material\u2010dependent, with feldspathic ceramics most affected and zirconia most stable. Microhardness generally decreased across ceramics. Fracture strength remained mostly unchanged, except for occasional reductions. Polymer\u2010infiltrated ceramics and zirconia showed the greatest color stability. Specimen shapes and dimensions varied across studies, reflecting differences in study aims and testing protocols. Most studies showed appropriate outcome reporting, statistical analysis, and test standardization (&gt;90%). However, operator blinding, when applicable, was not reported in any of the included studies. Randomization (&gt; 87%) and sample size calculation (50%) were also frequently missing.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Surface, mechanical, and optical properties of ceramics were affected by acid exposure, varying by material.
