Tissue Sample Collection and Analysis: Buccal mucosal biopsies were obtained from both OSMF patients and controls. The tissue copper concentrations were quantified using mass absorption spectrometry (MAS). Additionally, energy-dispersive X-ray microanalysis (EDX) was employed to identify the presence and distribution of copper in the tissue.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Statistical Analysis:<\/jats:title>\n                    <jats:p>\n                      Statistical comparisons were performed using appropriate methods, with a\n                      <jats:italic toggle=\"yes\">P-<\/jats:italic>\n                      value of less than 0.05 considered statistically significant.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      MAS analysis revealed that the mean tissue copper level was 6.2 \u00b1 3.1 micrograms per gram (\u03bcg\/g) in OSMF specimens (\n                      <jats:italic toggle=\"yes\">n<\/jats:italic>\n                      = 30), slightly higher than the 4.5 \u00b1 2.0 \u03bcg\/g in the nonareca chewing controls (\n                      <jats:italic toggle=\"yes\">n<\/jats:italic>\n                      = 30) (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.1).
