Periodontitis is a common oral disease mainly caused by bacterial infection and inflammation of the gingiva. In the prevention or treatment of periodontitis, anti-bacterial agents are used to inhibit pathogen growth, despite increasing levels of bacterial resistance. (SM) seed oil has proven anti-bacterial and anti-inflammation properties. However, the possibility of using this plant to prevent or treat periodontitis has not been reported previously. The aim of this study was to evaluate the effects of SM oil on experimental periodontitis in rats by using micro-CT and microbiota analysis. The distance between cementoenamel junction (CEJ) and alveolar bone crest (ABC) on the sagittal micro-CT slide showed that total bone loss (TBL) was significantly lower in CEJ-ABC distances between SM oil and SM oil-free groups on Day 14. Histology data also showed less alveolar bone resorption, a result consistent result with micro-CT imaging. The microbiota analyzed at phylum and class levels were compared between the SM oil and SM oil-free groups on Day 7 and Day 14. At the phylum level, , , , and were the dominant bacterium. in box plot analysis was significantly less in the SM oil group than in the SM oil-free group on Day 7. At the class level, , , , , and were the dominant bacteria. The bacteria composition proportion of , and could be seen in the SM oil group significantly less than in t SM oil-free group on Day 7. Overall, the present results show that topical application of SM oil can reduce bone resorption and change bacteria composition in the ligature-induced periodontitis model. According to these results, it is reasonable to suggest SM oil as a potential material for preventing oral disease.
牙周炎是一种常见的口腔疾病,主要由细菌感染和牙龈炎症引起。在预防或治疗牙周炎时,使用抗菌剂来抑制病原体的生长,但随着细菌耐药性的增加,效果并不理想。(SM)籽油具有良好的抗菌和抗炎特性。然而,以前没有报道过将这种植物用于预防或治疗牙周炎的可能性。本研究旨在通过微 CT 和微生物组分析评估 SM 油对实验性牙周炎大鼠的影响。矢状位微 CT 切片上釉牙骨质界 (CEJ)和牙槽嵴顶 (ABC)之间的距离显示,SM 油组的总骨损失 (TBL)在第 14 天明显低于 SM 油组和 SM 油组。组织学数据也显示出较少的牙槽骨吸收,这与微 CT 成像结果一致。在第 7 天和第 14 天比较了 SM 油组和 SM 油组之间的微生物群落在门和纲水平上的差异。在门水平上,、、、和 是优势菌。在 SM 油组中,在第 7 天明显少于 SM 油组。在纲水平上,、、、、和 是优势菌。在第 7 天,SM 油组中 、 和 的细菌组成比例明显低于 SM 油组。总的来说,这些结果表明,局部应用 SM 油可以减少骨吸收并改变结扎诱导的牙周炎模型中的细菌组成。根据这些结果,有理由认为 SM 油是一种预防口腔疾病的潜在物质。
