No obstant aix\u00f2, at\u00e8s que l&#8217;associaci\u00f3 entre totes dues condicions est\u00e0 ben documentada, la serologia del VHC ha de considerar-se part de l&#8217;estudi etiol\u00f2gic del LPO, especialment en les formes erosives o at\u00edpiques i en pacients amb factors de risc coneguts per a la infecci\u00f3.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">La cura de l&#8217;hepatitis C amb antivirals millora les lesions orals?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Les dades disponibles sobre l&#8217;evoluci\u00f3 del liquen pla oral i altres manifestacions mucoses despr\u00e9s de la curaci\u00f3 de l&#8217;hepatitis C amb AAD s\u00f3n variables.
