The occlusal enamel and infected dentin of the included samples were meticulously excised using a water-cooled, slow-speed device, resulting in a flat mid-coronal CAD surface. Based on the effectiveness of SL removal techniques, the samples were categorized into groups (\n                      <jats:italic toggle=\"yes\">n<\/jats:italic>\n                      = 11 each). Group 1: no treatment, Group 2: DL, Group 3: PDT-activated methylene blue (MB), Group 4: 16 ppm ozonated water, Group 5: 17% ethylenediamine tetra-acetic acid (EDTA), and Group 6: 37% phosphoric acid (PA). One pair of samples from each group was assessed under SEM following different conditioning regimes. The remaining samples underwent the application of an adhesive 7th-generation single-bottle adhesive and composite placement. All bonded samples were aged, and SBS assessment was performed via a universal testing machine, and unbonded surfaces were assessed under a stereomicroscope. A one-way analysis of variance was employed, followed by Tukey honestly significant difference (HSD) post hoc tests. Statistical significance was established at a\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      value of less than 0.05.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      The highest SL removal efficiency was observed in the PA group.
