本研究旨在探究革兰氏阴性肠杆菌和假单胞菌与粘膜炎和种植体周围炎之间的关联,种植体为粘接和螺钉固位。

纳入接受种植治疗,并被诊断为种植体周围粘膜炎和/或种植体周围炎的患者。此外,研究人员还探究了来自种植体两个相邻牙齿的龈沟重的微生物群。使用基质辅助激光解吸/电离飞行时间质谱法鉴定微生物。

在31名患者中评估了总共52颗粘接固位和51颗螺钉固位的种植体。粘接固定的修复体中,革兰氏阴性肠杆/假单胞菌的存在明显更高(P = .01)。以种植体为单位研究时,校正可能的混杂因素后,革兰氏阴性肠杆/假单胞菌的存在与粘接固定修复体相关(优势比[OR] = 3.7; 95%CI,1.4-10; P =0.01);此外,种植体周围炎在多变量模型中具有统计学意义(P = .008)。以患者作为分析单位时,种植体周围炎与粘接固定修复体相关(OR = 9.4; 95%CI,2-46; P = .006);校正潜在的混杂因素后,这种统计学上的显著关联仍然存在(OR = 6.8; 95%CI,1.3-37; P = .02)。

总之,该研究结果表明,革兰氏阴性肠杆/假单胞菌的存在与粘接固定修复有关;此外,种植体周围炎与粘接固定种植体有关。
