OBJECTIVES To retrospectively assess the periodontal conditions of teeth adjacent to and contralateral to implants presenting with or without peri-implantitis, following non-surgical periodontal and peri-implant mechanical therapy. MATERIALS AND METHODS One hundred and one patients with existing dental implants and chronic periodontitis, who underwent non-surgical periodontal and peri-implant mechanical therapy, were included. The periodontal clinical probing depth (PPD), gingival recession (GR), and bleeding on probing (BOP) were recorded at six sites around the adjacent (Adj-) teeth and the contralateral (CL-) teeth relative to the implant. The potential factors influencing the periodontal conditions of 316 teeth were analyzed by multivariate linear regression models with generalized estimating equation methods and α = .05. RESULTS The PPD of Adj-teeth was significantly different from that of CL-teeth before and after non-surgical therapy when the implant was diagnosed with peri-implantitis (PI) (p < .05). The PPD of teeth was shown to be affected by neighboring implants diagnosed with peri-implantitis (β = .825 mm, p < .001), teeth adjacent to implants (β = .245 mm, p = .004), a molar tooth type (β = .435 mm, p = .019), and non-surgical therapy (β = -.522 mm, p < .001). CONCLUSIONS Relatively compromised periodontal conditions at Adj-teeth after non-surgical PI therapy were detected. Therefore, clinicians should be aware that non-surgical therapy may be less successful at teeth adjacent to implants with PI.

牙周炎治疗患者非手术治疗后伴或不伴种植体周围炎的种植牙附近牙齿的牙周状况：一项回顾性研究。


目的 回顾性评估非手术牙周和种植体周围机械治疗后伴或不伴种植体周围炎的种植体附近和对侧牙齿的牙周状况。材料和方法 纳入 101 例接受非手术牙周和种植体周围机械治疗的现有种植牙和慢性牙周炎患者。牙周临床探诊深度 （PPD） 、牙龈萎缩 （GR） 和探诊出血 （BOP） 记录在相邻 （Adj-） 牙齿和对侧 （CL-） 牙齿相对于种植体的 6 个部位。采用广义估计方程法和多变量线性回归模型分析影响 316 颗牙齿牙周状况的潜在因素，α = .05。结果 当种植体被诊断为种植体周围炎 （PI） 时，Adj 牙的 PPD 与非手术治疗前后的 CL 牙的 PPD 显着不同 （p < .05）。牙齿的 PPD 显示受诊断为种植体周围炎的邻近种植体 （β = .825 mm， p < .001）、与种植体相邻的牙齿 （β = .245 mm， p = .004）、磨牙类型 （β = .435 mm， p = .019） 和非手术治疗 （β = -.522 mm， p < .001） 的影响。结论 在非手术 PI 治疗后检测到 Adj 牙的牙周病相对受损。因此，临床医生应该意识到，非手术治疗对 PI 种植体附近的牙齿可能不太成功。
