Abstract
BACKGROUND: The majority of current researches focus on the influence of non-precious metal ceramic porcelain and metal ceramic porcelain on the gingival and periodontal tissue health, but few study reports the effect of pure titanium versus non-precious metals and precious metals.OBJECTIVE: To investigate the changes of gingival crevicular fluid (GCF) secretion, and the level of tumor necrosis factor-α (TNF-α) and interleu kin-6 (IL-6) in GCF during different materials of porcelain fused-to-metal crowns restoration.METHODS: Sixty patients including 80 premolar and molar teeth were involved as test teeth and divided into three groups according to the materials of porcelain fused-to-metal crowns, Co-Cr alloy group (n=28), pu re Ti alloy group (n=32) and gold-platinum alloy group (n=30). At 1 and 3 months after the restorations of crowns, the secretion amounts of GCF, the levels of TNF-α and IL-6 in GCF were detected.RESULTS AND CONCLUSION: The amounts of GCF, the levels of TNF-α and IL-6 in GCF in Co-Cr alloy group at 1 and 3 months post-restoration were remarkably higher than those before restoration (P ＜ 0.05). In Ti alloy group, the secretion of GCF and level of TNF-α were increased compared with before restoration (P ＜ 0.05), but no differences were found in IL-6 (P ＞ 0.05).At 1 and 3 months post-restoration, there was no significant difference in various indicators of gold-platinum alloy group compared with before restoration (P ＞ 0.05). The secretion of GCF, the levels of TNF-α and IL-6 in Co-Cr alloy group were higher than those in Ti alloy group and gold-platinum alloy group (P ＜ 0.05). In addition, the amount of GCF and level of TNF-α in Ti alloy group were higher than gold-platinum alloy group (P ＜ 0.05).关键词
