C-reactive protein (CRP) is an acute phase reactant and has been proved to be a significant predictor of future cardiovascular events. Recent studies have demonstrated a correlation between periodontitis and elevated CRP levels. However, comparison between the levels of CRP in two main forms of periodontitis is ambiguous. This study aims at determining and comparing the relative levels of serum CRP in aggressive and chronic periodontitis patients.
A total of 240 systemically healthy subjects were divided into three groups of 80 based on having generalized aggressive periodontitis, chronic generalized periodontitis and non-periodontitis (NP; controls). Venous blood samples were collected for quantitative CRP analysis using turbidimetric immunoassay.
Mean CRP levels were significantly greater in both generalized aggressive periodontitis (7.49±2.31 mg/l) and chronic generalized periodontitis (4.88±1.80 mg/l) groups as compared to NP (0.68±0.23 mg/l) controls. Moreover, CRP levels were significantly higher in aggressive periodontitis as compared to chronic periodontitis patients. Also, CRP levels positively correlated with the amount of periodontal destruction as measured by probing depth and clinical attachment loss for both chronic generalized periodontitis and generalized aggressive periodontitis.
Findings of the present study indicated that periodontitis should be of particular concern in younger individuals, where elevated levels of CRP may contribute to early or more rapid cardiovascular disease in susceptible patients. Thus, further research should be carried out at a community level to ascertain these findings.
C反应蛋白(CRP)是一种急性期反应物,已被证明是未来心血管事件的重要预测指标。最近的研究表明牙周炎与CRP水平升高之间存在关联。然而,两种主要形式的牙周炎中CRP水平的比较尚不明确。本研究旨在测定和比较侵袭性牙周炎和慢性牙周炎患者血清CRP的相对水平。
总共240名全身健康的受试者根据是否患有广泛型侵袭性牙周炎、慢性广泛型牙周炎和非牙周炎(NP;对照组)分为三组,每组80人。采集静脉血样,采用比浊免疫分析法进行CRP定量分析。
与NP(0.68±0.23mg/l)对照组相比,广泛型侵袭性牙周炎组(7.49±2.31mg/l)和慢性广泛型牙周炎组(4.88±1.80mg/l)的平均CRP水平均显著更高。此外,侵袭性牙周炎患者的CRP水平显著高于慢性牙周炎患者。而且,对于慢性广泛型牙周炎和广泛型侵袭性牙周炎,CRP水平与通过探诊深度和临床附着丧失测量的牙周破坏量呈正相关。
本研究结果表明,牙周炎在年轻人中应特别引起关注,在易感患者中,CRP水平升高可能导致早期或更快速的心血管疾病。因此,应在社区层面开展进一步研究以确定这些发现。
