摘要
目的:了解镍铬合金烤瓷冠对牙周组织的影响。方法:选择临床病例24例,共29颗镍铬合金烤瓷冠修复的上颌前磨牙,以患牙的对侧同名健康牙为对照牙,在烤瓷冠戴入6-9个月后复诊,进行牙周临床检查,分别吸取患牙及对照牙的龈沟液并定量,在实验室对龈沟液中的白细胞介素-1β(IL-1β)和天门冬氨酸转氨酶(AST)进行分析。结果:符合临床合格要求的镍铬合金烤瓷冠修复后,患牙的菌斑指数、龈沟液量没有明显改变,但探诊深度、龈沟内出血指数、龈沟液内IL-1β、AST水平增高。结论:临床合格的镍铬合金烤瓷冠对患牙的牙周组织有一定的不良影响。
Objective： To detect the effects of Ni-Cr based Porcelain-fused-to-metal（PFM）crown on the periodontal tissue. Methods： 29 maxillary incisors in 24 patients with Ni-Cr based PFM crowns were included in this study with contralateral homonymy natural teeth as control teeth. The patients were followed up 6 to 9 months after crowns placement. The gingival crevicular fluid （GCF） samples were collected and weighed. Then the clinical parameters such as plaque index （PLI）. probing depth （PD） and sulcus bleeding index （SBI） were recorded for the test and control groups. IL-1β and AST levels of GCF were analysed. Results： After the placement of Ni-Cr based PFM which was clinically accepted, although the changes of GCF volume and PLI were insignificant, the concentration of IL-1β AST. PD and SBI increased. Conclusion： Ni-Cr based PFM crowns which clinically accepted have negative influences on periodontal tissue.
