The association between tumor necrosis factor-alpha (TNF-α-308G/A, -238G/A, -863C/A, -1031T/C, and -857C/T) polymorphism and either chronic (CP) or aggressive (AgP) periodontitis susceptibility was conflicting. This meta-analysis aimed to quantitatively estimate the association.A total of 52 studies involving 5519 patients and 7260 controls were identified through a search of multiple electronic databases. Odds ratios (ORs) and their 95% confidence intervals using allele, homozygous, heterozygous, dominant, and recessive genetic models were computed to assess the strength of the association.The TNF-α-308G/A polymorphism was significantly associated with decreased risks of CP (GG vs AA: OR = 0.353, P < .001; GG+GA vs AA: OR = 0.480, P < .001) and AgP (G vs A: OR = 0.651, P < .001; GG vs AA: OR = 0.306, P < .001; GG+GA vs AA: OR = 0.384, P < .001) in Asians. There were no associations between TNF-α-238G/A, -863C/A, -1031T/C, -857C/T polymorphism and susceptibility to AgP. No associations were also found between CP susceptibility and TNF-α-238G/A, -857C/T polymorphism.These findings supported that TNF-α-308G/A polymorphism might be the protective factors of CP and AgP in Asians, and TNF-α-238G/A, -863C/A, -1031T/C, -857C/T polymorphism is not linked to AgP susceptibility.
肿瘤坏死因子-α(TNF-α -308G/A、-238G/A、-863C/A、-1031T/C和-857C/T)基因多态性与慢性牙周炎(CP)或侵袭性牙周炎(AgP)易感性之间的关联存在争议。本荟萃分析旨在定量评估这种关联。通过检索多个电子数据库,共纳入52项研究,涉及5519例患者和7260例对照。计算等位基因、纯合子、杂合子、显性和隐性遗传模型的比值比(OR)及其95%置信区间,以评估关联强度。TNF-α -308G/A基因多态性与亚洲人患CP风险降低显著相关(GG与AA:OR = 0.353,P < 0.001;GG + GA与AA:OR = 0.480,P < 0.001)以及与AgP风险降低显著相关(G与A:OR = 0.651,P < 0.001;GG与AA:OR = 0.306,P < 0.001;GG + GA与AA:OR = 0.384,P < 0.001)。TNF-α -238G/A、-863C/A、-1031T/C、-857C/T基因多态性与AgP易感性之间无关联。CP易感性与TNF-α -238G/A、-857C/T基因多态性之间也未发现关联。这些发现支持TNF-α -308G/A基因多态性可能是亚洲人CP和AgP的保护因素,而TNF-α -238G/A、-863C/A、-1031T/C、-857C/T基因多态性与AgP易感性无关。
