J Dent:种植体周围炎植体邻近天然牙的牙周状态如何?

2018-02-03 MedSci MedSci原创

本研究旨在评估种植体周围炎与邻牙牙周健康的关系,以及伴或不伴有种植体周围炎的植体邻牙及对侧牙牙周状态与种植体周围炎的关系。 在这个横断面研究中,研究人员检查了53名有现有牙种植体和慢性牙周炎的受试者。将70颗种植体分为种植体周围炎组(n = 42)和健康/粘膜炎组(n = 28)。在种植体周围的6个位点以及与这些种植体相邻和对侧的牙齿的6个位点测量牙周和种植体周围的状态,包括探测深度(PD)、临床

本研究旨在评估种植体周围炎与邻牙牙周健康的关系,以及伴或不伴有种植体周围炎的植体邻牙及对侧牙牙周状态与种植体周围炎的关系。

在这个横断面研究中,研究人员检查了53名有现有牙种植体和慢性牙周炎的受试者。将70颗种植体分为种植体周围炎组(n = 42)和健康/粘膜炎组(n = 28)。在种植体周围的6个位点以及与这些种植体相邻和对侧的牙齿的6个位点测量牙周和种植体周围的状态,包括探测深度(PD)、临床附着水平(CAL)和牙龈退缩(GR)。在70个牙齿/种植体的总共560个部位中,检查了牙齿近侧和远侧部位(根据植入物)的牙周状态与植入物状态(有/无种植体周围炎)之间的关联。

结果显示,与邻近和对侧牙齿的远离部位以及对侧牙齿的邻近部位相比,种植体周围炎植体邻近部位的平均PD(5.01±1.69,4.42±1.8,3.55±0.88和3.71±1.07mm,p <0.001)和CAL(6.02±2.36,4.89±2.04,4.35±1.11和4.35±1.5mm,p <0.001)差异明显。使用广义估计方程(GEE),种植体周围炎(β= 1.041mm,置信区间= 0.646-1.435,p <0.001;β= 0.857mm,置信区间= 0.279-1.434,p <0.004)和牙位置(β= 0.65mm,置信区间= 0.4-0.9,p <0.001;β= 0.682mm,置信区间= 0.34-1.024,p <0.001)与牙齿的PD值和CAL值明显相关。此外,检查部位(即牙齿的近端和远端部位)与CAL(β= 0.304mm,置信区间= 0.019-0.588,p = 0.036)和GR(β= 0.136mm,置信区间= 0.02-0.252,p = 0.022)明显相关。

综上所述,该研究结果表明,种植体周围炎、牙齿位置和检查部位与余牙的牙周参数明显相关。
