To evaluate the relationship between peri-implantitis and the periodontal health of the adjacent tooth, the periodontal status of the teeth adjacent and contralateral to the implants with and without peri-implantitis.
Fifty-three subjects with existing dental implants and chronic periodontitis were examined in this cross-sectional study. Seventy implants were categorized into peri-implantitis (n = 42) and healthy/mucositis (n = 28) groups. The periodontal and peri-implant status, including probing depth (PD), clinical attachment level (CAL), and gingival recession (GR) were measured at 6 sites around the implants and the teeth adjacent and contralateral to those implants. In total 560 sites of the 70 teeth/implant sets, the association between the periodontal status at the near and away sites of the teeth (according to implant) and the implant status (without/with peri-implantitis) was examined.
A significantly different mean PD (5.01 ± 1.69, 4.42 ± 1.8, 3.55 ± 0.88, and 3.71 ± 1.07 mm, p < 0.001) and CAL (6.02 ± 2.36, 4.89 ± 2.04, 4.35 ± 1.11, and 4.35 ± 1.5 mm, p < 0.001) were noted at the near sites of the teeth adjacent to the implants with peri-implantitis when compared with the away sites of adjacent and contralateral teeth and the near sites of contralateral teeth. With generalized estimating equation (GEE), the presence of peri-implantitis (β = 1.041 mm, confidence interval = 0.646-1.435, and p < 0.001; β = 0.857 mm, confidence interval = 0.279-1.434, and p < 0.004) and tooth location (β = 0.65 mm, confidence interval = 0.4-0.9, and p < 0.001; β = 0.682 mm, confidence interval = 0.34-1.024, and p < 0.001) were significantly associated with the values of the PD and CAL of the teeth. Moreover, the factor of examining sites (i.e. near and away sites of the tooth) was significantly associated with CAL (β = 0.304 mm, confidence interval = 0.019-0.588, and p = 0.036) and GR (β = 0.136 mm, confidence interval = 0.02-0.252, and p = 0.022).
The existence of peri-implantitis, the tooth location, and the examining site are significantly associated with the periodontal measurements of the remaining teeth.
Peri-implant health is related to the periodontal health of the natural teeth close to the dental implant.
评估种植体周围炎与邻牙牙周健康的关系，以及种植体周围炎和健康/黏膜炎种植体的邻牙和对侧牙的牙周状况。
本横断面研究纳入了 53 名存在种植牙且患有慢性牙周炎的患者。70 个种植体分为种植体周围炎（n=42）和健康/黏膜炎（n=28）两组。在种植体及邻牙和对侧牙的 6 个位点测量牙周和种植体状况，包括探诊深度（PD）、临床附着水平（CAL）和牙龈退缩（GR）。在总共 70 个牙/种植体组的 560 个位点上，根据种植体检查了近远位牙齿（邻牙）的牙周状况与种植体状况（有无种植体周围炎）之间的关系。
与邻牙和对侧牙的远位相比，种植体周围炎组邻牙的近位位点的平均 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）显著更高。使用广义估计方程（GEE），种植体周围炎的存在（β=1.041mm，置信区间为 0.646-1.435，p<0.001；β=0.857mm，置信区间为 0.279-1.434，p<0.004）和牙齿位置（β=0.65mm，置信区间为 0.4-0.9，p<0.001；β=0.682mm，置信区间为 0.34-1.024，p<0.001）与牙齿 PD 和 CAL 值显著相关。此外，检查部位（即牙齿的近位和远位）这一因素与 CAL（β=0.304mm，置信区间为 0.019-0.588，p=0.036）和 GR（β=0.136mm，置信区间为 0.02-0.252，p=0.022）显著相关。
种植体周围炎的存在、牙齿位置和检查部位与剩余牙齿的牙周测量值显著相关。
种植体周围健康与种植牙附近天然牙齿的牙周健康有关。
