Evaluación del esmalte dentario después de remover la resina residual posterior al descementado de brackets a través de dos tipos de sistemas

Abstract

An orthodontist should complete a patient’s treatment of oral tissues in optimal health conditions. The purpose of this study was to determine whether post treatment damage had occurred subsequent to polishing after debonding brackets. The study involved 60 extracted premolars, divided into two groups of 30, called A and B, in which high-speed tungsten-carbide bur (12-blades) were used for Group A, followed by the use of sof-lex discs, and low-speed tungsten-carbide bur (12-blades) followed by sof-lex discs were used for Group B. All teeth were examined in three stages, the first, prior to bracket placement, the second, after debonding, and the third stage, the final polishing of the enamel. The degree of damage to the enamel was determined by EDI and ARI, which were analyzed through a Microstar F1 microscope, model series OM 100 OM100F1R00008031100, as well as a PROCAM Power Supply camera, series HC220RX110110117, and through an endoDIGI software, series EN1022R0008031100 (ECLERIS). The Friedman Test, chi square, and Fisher Test was conducted to determine whether or not there were any significant differences between both groups. The following results were obtained: the use of high-speed tungsten-carbide bur had significantly increased the damage, which had in turn added to the risk of polishing damage by 2.47 over the use of low-speed tungstencarbide bur, (95% CI 1.55 to 3.94). In conclusion, the most effective polishing system is achieved with low speed tungsten-carbide bur
