The aim of this study was to evaluate the effect of cemented bands and enamel bonded attachments on the gingival health of second molars. In 23 patients the right upper and lower second molars were banded, while the left upper and lower second molars were bonded. The plaque index, the gingival index, and pocket depths were greater and statistically significant on the right side, indicative of increased inflammatory activity where bands were cemented. Once the appliances were removed, both areas returned to pretreatment levels.
本研究的目的是评估黏固带环和釉质黏接附件对第二磨牙牙龈健康的影响。在23例患者中，右上和右下第二磨牙使用带环，而左上和左下第二磨牙使用黏接附件。右侧的菌斑指数、牙龈指数和牙周袋深度更高且具有统计学意义，表明在黏固带环的部位炎症活动增加。一旦去除矫治器，两个部位均恢复到治疗前水平。
