Abstract

Objective: Hormone replacement therapy (HRT) is a commonly used strategy for treating menopausal symptoms, while its relation with periodontitis remains unclear. This study aimed to explore the potential effects of HRT on periodontitis, mainly in aspects of bone loss and inflammation.

Methods: The alveolar bone height (ABH), alveolar bone thickness (ABT), and bone mineral density (BMD) were measured in menopausal women with periodontitis who had received HRT or had not received HRT by cone beam computed tomography. Based on a rat model of periodontitis, the alveolar bone loss was evaluated by micro-computed tomography and bone-related biochemical markers. The expression/levels of inflammatory markers were measured to reflect periodontal inflammation.

Results: Although the differences were not all significant in each premolars/molars, the mesial/distal ABH and buccal/lingual ABT were lower, and the mesial/distal BMD was higher in patients in the HRT group than those in the control group. In a rat model of periodontitis, the alveolar bone loss was relieved by HRT. Additionally, HRT significantly weakened the elevation of inflammatory markers, including TNF-α, IL-1β, and IL-6 in periodontitis rats.

Conclusions: HRT contributes to the remission of periodontitis by inhibiting alveolar bone loss and inflammation.

激素替代疗法通过抑制牙槽骨流失和炎症缓解牙周炎

目的：激素替代疗法（HRT）是治疗更年期症状的常用方法，但它与牙周炎的关系仍不清楚。本研究旨在探讨激素替代疗法对牙周炎的潜在影响，主要是在骨质流失和炎症方面：方法：通过锥形束计算机断层扫描测量了接受过或未接受过 HRT 的绝经期女性牙周炎患者的牙槽骨高度（ABH）、牙槽骨厚度（ABT）和骨矿物质密度（BMD）。在大鼠牙周炎模型的基础上，通过微型计算机断层扫描和骨相关生化标记物对牙槽骨损失进行了评估。测量了反映牙周炎症的炎症标志物的表达/水平：结果：虽然各前磨牙/臼齿的差异并不显著，但与对照组相比，HRT 组患者的中/远端 ABH 和颊/舌 ABT 更低，而中/远端 BMD 更高。在牙周炎大鼠模型中，HRT 可缓解牙槽骨流失。此外，HRT还能明显减弱牙周炎大鼠体内TNF-α、IL-1β和IL-6等炎症指标的升高：结论：通过抑制牙槽骨流失和炎症，HRT 有助于缓解牙周炎。

期刊介绍： Oral Diseases is a multidisciplinary and international journal with a focus on head and neck disorders, edited by leaders in the field, Professor Giovanni Lodi (Editor-in-Chief, Milan, Italy), Professor Stefano Petti (Deputy Editor, Rome, Italy) and Associate Professor Gulshan Sunavala-Dossabhoy (Deputy Editor, Shreveport, LA, USA). The journal is pre-eminent in oral medicine. Oral Diseases specifically strives to link often-isolated areas of dentistry and medicine through broad-based scholarship that includes well-designed and controlled clinical research, analytical epidemiology, and the translation of basic science in pre-clinical studies. The journal typically publishes articles relevant to many related medical specialties including especially dermatology, gastroenterology, hematology, immunology, infectious diseases, neuropsychiatry, oncology and otolaryngology. The essential requirement is that all submitted research is hypothesis-driven, with significant positive and negative results both welcomed. Equal publication emphasis is placed on etiology, pathogenesis, diagnosis, prevention and treatment.
