在移除固定的正畸矫治器后进行牙釉质清理时，空气中会产生微粒。空气动力学直径小于2.5微米的颗粒，即PM2.5，可以到达肺泡。本实验的目的是定性地确定在正畸治疗结束时牙釉质清理过程中是否会产生这些颗粒。收集颗粒并在扫描电子显微镜下检查。颗粒的空气动力学直径约为2至30微米。x射线分析不仅证实了黏合剂成分的存在，还证实了牙柄和牙釉质中的钨。综上所述，正畸治疗完成后，牙釉质清理过程中会产生可吸入颗粒。需要进一步的研究来确定这些颗粒的临床意义，如何最大限度地减少它们的产生，以及是否会产生更小的、细小的或超细的颗粒。
Airborne particles can be produced during enamel cleanup after the removal of fixed orthodontic appliances. Particles with an aerodynamic diameter of less than 2.5 mum, known as PM2.5, can reach the alveoli of the lungs. The aim of this experiment was to qualitatively determine whether such particles are produced during enamel cleanup at the end of orthodontic treatment. Particles were collected and examined under a scanning electron microscope. Aerodynamic diameters of the particles ranged from approximately 2 to 30 mum. X-ray analysis confirmed not only the presence of components of the adhesives being removed, but also tungsten from the bur and tooth enamel. In conclusion, inhalable particles can be produced during enamel cleanup at the completion of orthodontic treatment. Further investigation is required to determine the clinical significance of such particles, how their production can be minimized, and whether even smaller, fine or ultrafine, particles are produced.
