This study aimed to assess the effectiveness of the treatment with alpha-terpineol (αTPN) complexed with beta-cyclodextrin (βCD) on oral, blood, and hepatic parameters in ligature-induced periodontitis.
Forty female rats were distributed among the following groups: control (vehicle solution), periodontitis (ligature + vehicle solution), 5 mg/kg of αTPN-βCD (ligature), and 25 mg/kg of αTPN-βCD (ligature). Compounds were administered daily via intraperitoneal injection over a 20-day period. Periodontitis was induced with the bilateral insertion of ligatures around the first lower molars of each rat. Oral parameters, as well as blood biomarkers, were measured: histopathological assessment of the hepatic tissue was carried out using light and transmission electron microscopy.
The treatment with αTPN-βCD significantly improved several oral parameters and blood biomarkers in comparison with rats with periodontitis. In addition, the treatment with αTPN-βCD significantly ameliorated the steatosis score and reduced the number of lipid droplets and the amount of foamy cytoplasm in the hepatocytes of rats with periodontitis.
The results obtained suggest that the treatment with αTPN-βCD improves several oral and blood parameters in rats with experimental periodontitis. In addition, hepatic alterations caused by periodontitis were ameliorated in the rats treated with αTPN-βCD.
本研究旨在评估α-松油醇(αTPN)与β-环糊精(βCD)复合物治疗结扎诱导牙周炎的口腔、血液和肝脏参数的效果。
40 只雌性大鼠分为以下几组:对照组(载剂溶液)、牙周炎组(结扎+载剂溶液)、5mg/kg αTPN-βCD 组(结扎)和 25mg/kg αTPN-βCD 组(结扎)。复合物通过腹腔注射,每日一次,共 20 天。通过在每只大鼠的第一下磨牙周围插入双侧结扎线来诱导牙周炎。测量口腔参数和血液生物标志物:使用光镜和透射电镜对肝组织进行组织病理学评估。
与牙周炎大鼠相比,αTPN-βCD 治疗显著改善了多项口腔参数和血液生物标志物。此外,αTPN-βCD 治疗显著改善了牙周炎大鼠的脂肪变性评分,并减少了肝细胞中的脂滴数量和泡沫细胞质含量。
研究结果表明,αTPN-βCD 治疗可改善实验性牙周炎大鼠的多项口腔和血液参数。此外,αTPN-βCD 治疗还改善了牙周炎大鼠的肝脏改变。
