Bacterial pathogens in dental plaque are necessary for the development of periodontitis but this etiology alone does not explain all its clinicopathologic features. Researchers have proven the role of certain viruses like herpes virus in periodontal disease which implies that other viral agents like human papilloma virus may also be involved.
This cross-sectional study was conducted to determine the proportion of patients with human papilloma virus (HPV-16) in marginal periodontium by analyzing DNA from the gingival tissue sample and to understand its association with periodontitis.
102 systemically healthy patients between the age group of 15 and 70 years reporting to the Department of Periodontology who required surgical intervention (flap surgery for patients with periodontitis and crown lengthening for healthy patients) with internal bevel gingivectomy were selected.
After scaling and root planning, gingival tissue was collected during the respective surgical procedure. DNA was isolated and amplified using specific primers for HPV-16 by polymerase chain reaction (PCR). The amplified products were checked by agarose gel electrophoresis.
No HPV DNA was detected in the 102 samples analyzed.
Marginal periodontium does not contain HPV in this study population and hence there was no association between HPV and periodontitis.
牙菌斑中的细菌病原体是牙周炎发展所必需的,但仅这种病因并不能解释其所有的临床病理特征。研究人员已经证实某些病毒(如疱疹病毒)在牙周疾病中的作用,这意味着其他病毒病原体(如人乳头瘤病毒)也可能参与其中。
本横断面研究旨在通过分析牙龈组织样本中的DNA来确定边缘性牙周组织中人乳头瘤病毒(HPV - 16)阳性患者的比例,并了解其与牙周炎的关联。
选取102例年龄在15至70岁之间、全身健康、到牙周病科就诊且需要进行手术干预(牙周炎患者行翻瓣手术,健康患者行牙冠延长术)并采用内斜切口牙龈切除术的患者。
在进行洁治和根面平整后,于相应手术过程中采集牙龈组织。通过聚合酶链反应(PCR)使用针对HPV - 16的特异性引物分离并扩增DNA。扩增产物通过琼脂糖凝胶电泳进行检测。
在分析的102个样本中未检测到HPV DNA。
在本研究人群中,边缘性牙周组织不含HPV,因此HPV与牙周炎之间无关联。
