Resumen
Los dientes que reciben tratamiento de ortodoncia se someten a una serie de procedimientos que implican modificación de la estructura del esmalte dental, la adhesión y descementación de brackets implican maniobras que afectan esta estructura, se ha reportado que al descementar brackets, en el esmalte dental se pueden producir grietas o fracturas las cuales son evidentes al microscopio, sin embargo los procesos de limpieza dental como retiro de resina residual también implican algún tipo de daño en la estructura del esmalte. El presente trabajo busca reparar los daños en el esmalte como grietas o fisuras que se presentan posterior a la descementación de brackets metálicos, aplicando una sustancia remineralizante (SR) sobre la superficie vestibular de premolares extraídos por motivos ortodónticos, se tomaron imágenes iniciales posterior a la descementación de brackets y retiro de resina residual, la sustancia fue aplicada durante 3 horas y media, los dientes se lavaron y posteriormente se observaron al microscopio electrónico de barrido (SEM) para evaluar la reparación de grietas previamente establecidas. Además se realizó el análisis de composición química por energía dispersiva de rayos X (EDAX) en los dientes posterior a la aplicación de la SR. Los resultados muestran evidente reparación de algunas grietas, en las cuales se observó reducción en su grosor y tamaño.
Abstract. Teeth that receive orthodontia treatment are subject to a series of procedures that implicate the modification of the tooth enamel structure. The attachment and de-cementation of braces imply maneuvers that affect this structure. lt has been reported that while de-cementing brackets, cracks o fractures can be produced in the tooth enamel which are visible under a microscope. Nevertheless, the processes of dental cleansing and resin withdrawal also bring upon some sort of damage to the enamel structure. The current work seeks to repair damage in the enamel such as cracks or fissures that present themselves after the de-cementation of metallic brackets, applying a re-mineralizing substance (RS) over the vestibular surface of premolars extracted for orthodontia reasons. Initial images were taken following the removal of the residual resin. The substance was applied for 3.5 hours and the teeth were washed. Afterwards, these were observed under an electronic microscope (SEM type) to evaluate the repair of previously established cracks. Furthermore, a chemical composition analysis by X-Ray dispersive energy (EDAX) was performed on the teeth after the application of the RS. The results show evident repair of some cracks that displayed reduction of thickness and size.
