背景:种植体周围炎(PI)是一种常见的炎症性疾病,其特征是支持骨的进行性丧失。并非所有具有公认危险因素的患者都会发生PI。这项研究的目的是评估使用巴斯克地区(西班牙)牙科植入物治疗的人群中炎症和骨代谢相关蛋白的单核苷酸多态性(SNP)的存在。
方法:我们包括80例诊断为PI的患者和81例无PI的患者。91名女性和70名男性,平均年龄60.90岁.BMP-4、BRINP3、CD14、FGF-3、FGF-10、GBP-1、IL-1α、IL-1β,IL-10,LTF,选择OPG和RANKL蛋白。我们使用IBMSPSS®v.28统计软件进行了单变量和双变量分析。
结果:SNPsGBP1rs7911(p=0.041)和BRINP3rs1935881(p=0.012)的存在在PI患者中更为常见。吸烟(>10μg/天)的PI患者显示出更高的OPGrs2073617SNP存在(p=0.034)。此外,BMP-4rs17563(p=0.018)和FGF-3rs1893047(p=0.014)SNP在PI和II型糖尿病患者中更为常见。
结论:我们的研究结果表明,牙种植体骨整合的改变可能有利于PI,基于来自巴斯克地区(西班牙)的患者对植入物周围感染的异常免疫反应。
BACKGROUND: Peri-implantitis (PI) is a frequent inflammatory disorder characterised by progressive loss of the supporting bone. Not all patients with recognised risk factors develop PI. The aim of this study is to evaluate the presence of single nucleotide polymorphisms (SNP) of inflammatory and bone metabolism related proteins in a population treated with dental implants from the Basque Country (Spain).
METHODS: We included 80 patients with diagnosis of PI and 81 patients without PI, 91 women and 70 men, with a mean age of 60.90 years. SNPs of BMP-4, BRINP3, CD14, FGF-3, FGF-10, GBP-1, IL-1α, IL-1β, IL-10, LTF, OPG and RANKL proteins were selected. We performed a univariate and bivariate analysis using IBM SPSS® v.28 statistical software.
RESULTS: Presence of SNPs GBP1 rs7911 (p = 0.041) and BRINP3 rs1935881 (p = 0.012) was significantly more common in patients with PI. Patients with PI who smoked (> 10 cig/day) showed a higher presence of OPG rs2073617 SNP (p = 0.034). Also, BMP-4 rs17563 (p = 0.018) and FGF-3 rs1893047 (p = 0.014) SNPs were more frequent in patients with PI and Type II diabetes mellitus.
CONCLUSIONS: Our findings suggest that PI could be favoured by an alteration in the osseointegration of dental implants, based on an abnormal immunological response to peri-implant infection in patients from the Basque Country (Spain).
