Abstract

AIM

To evaluate the correlation between standard clinical findings, radiographic (OPT) and magnetic resonance imaging (MRI) as well as to assess whether MRI is capable of providing additional information related to the severity and extent of periodontal disease.

METHODS

42 patients with generalized periodontitis received pre-interventional MRI scans. These were compared to MR images of a periodontal healthy control group (n = 34). The extent of the osseous oedema, detected by MRI, was set in correlation with clinical periodontitis-associated findings.

RESULTS

A highly significant correlation between bone oedema and clinical testings such as probing depth (p < 0.0001) and bleeding on probing (p < 0.0001) was revealed. The oedema exceeded the extent of demineralized bone. Patients with a positive BOP test showed a 2.51-fold increase in risk of already having a bone oedema around the respective tooth even if probing depth was ≤3 mm (logistic binary regression analysis, OR 2.51; 95% CI: 1.54-4.11; p < 0.0001).

CONCLUSION

MRI findings correlated with standard clinical findings, and MRI was able to depict intraosseous changes before any osseous defect had occurred.

摘要

目的

评估标准临床发现、影像学（OPT）和磁共振成像（MRI）之间的相关性，并评估 MRI 是否能够提供与牙周病严重程度和范围相关的额外信息。

方法

42 例广泛性牙周炎患者接受了术前 MRI 扫描。将这些与牙周健康对照组的 MRI 图像（n=34）进行比较。通过 MRI 检测到的骨水肿程度与临床牙周炎相关发现相关联。

结果

MRI 检测到的骨水肿与临床检查（如探诊深度（p<0.0001）和探诊出血（p<0.0001））之间存在高度显著相关性。水肿超过脱矿骨的范围。BOP 测试阳性的患者即使探诊深度≤3mm，其相应牙齿周围也有骨水肿的风险增加 2.51 倍（逻辑二元回归分析，OR 2.51；95%CI：1.54-4.11；p<0.0001）。
