摘要
目的:探讨纯钛烤瓷全冠修复对患牙牙周组织的影响。方法:选择临床接受纯钛烤瓷冠修复患者38例,共40颗的上颌前磨牙,以患牙的对侧同名健康牙为对照组。在纯钛烤瓷冠修复前、修复后6个月、12个月时,分别对患牙及对照牙进行临床检查和取龈沟液(gingival crevicular fluid,GCF),进行GCF量和可溶性细胞间粘附分子-1(soluble intercellular adhesion molecule-1,sICAM-l)、肿瘤坏死因子-ɑ(tumor necrosis factor-ɑ,TNF-ɑ)水平的测定。结果:修复后12个月时,纯钛组、对照组龈沟液中sICAM-l、TNF-ɑ水平分别为63.19±21.26(ng/ml)、61.21±20.53(ng/ml)和3.40±3.23(ng/ml)、3.32±2.34(ng/ml),差异均无统计学意义(P>0.05)。结论:纯钛烤瓷全冠不会对牙周组织健康产生明显不利影响。
Objective： To investigate the effect of pure titanium PFM on the periodontal tissue health of the restored teeth.Methods： 38 patients with 40 premolars were selected and restored by pure titanium PFM with contralateral homonymy natural teeth as control teeth.GCF was collected from labial and lingual of mesial site and distal site before the tooth preparation by filter paper.At the point of 6-month,12-month after cementation,GCF were collected at the same site.The level of sICAM-l and TNF-ɑ were detected by enzyme-linked-immunoadsorbent assay（ELISA） method.Results： At the point of 12-month after cementation,the level of sICAM-l and TNF-ɑ were 63.19±21.26（ng/ml）、61.21±20.53（ng/ml）and 3.40±3.23（ng/ml）、3.32±2.34（ng/ml）,respectively,for pure titanium PFM group and control group,and no significant difference were found（P 0.05）.Conclusion： Pure titanium PFM has no bad effect on the peirodontal tissue.
