Evaluación del daño genotóxico asociado a la presencia de la aparatología ortodóncica fija gemelar y de autoligado metálica en pacientes atendidos en la clínica de ortodoncia de la Universidad Cooperativa de Colombia -campus Pasto

Resumen

Fixed orthodontic appliances are made up of different attachments such as archwires, brackets, tubes, bands, springs, metal ligatures, among others, made with various metal alloys, which, due to the average time of appliance use, interact with oral tissues. including gum and oral mucosa. Of the chemical constituents of dental alloys, the use of nickel is very wide and varied in orthodontic accessories, ranging from brackets and bands to tubes and archwires, being in some cases used during all orthodontic treatment and the numerous techniques offered to the dentist. patient. Orthodontic appliances contain a variety of metal alloys that can remain in the mouth for several years, whose interaction with the oral environment has been the subject of many debates. The oral environment, due to its enzymatic, thermal, microbiological and chemical characteristics, can generate the degradation of the metals of which orthodontic devices are composed as a consequence of chemical reactions.
