Periodontitis is a common disorder that leads to the loss of both tooth and personal well-being, contributing to worsen the risk for metabolic and cardiovascular diseases. Recently, probiotics, characterized by rapid oral dispersion, have been topically used. Here, we present data of a mucoadhesive gel containing probiotics, capable of ensuring a slow release of bacteria to prevent and treat periodontitis.
An original mucoadhesive gel (AL0005) that is anhydrous and of food grade, loaded with the blend of lactobacilli and plants' dry extracts, has been assayed.
The release kinetics of the bacterial mixture in different experimental models , including simulated saliva or physiological solutions, showed a significant and stable release for 5-8 hours. In one study of a mouse model of periodontitis, a locally applied mucoadhesive gel enriched with probiotic strains improved significantly the tissue pathology when compared with vehicle-exposed mice.
Together, the results suggest that this mucoadhesive gel can be useful in the normalization of the gum bacterial flora and improvement of the tissue pathology of gum disorders.
牙周炎是一种常见疾病,会导致牙齿脱落和个人健康受损,增加代谢性疾病和心血管疾病的风险。最近,具有快速口腔分散特性的益生菌已被局部应用。在此,我们展示了一种含有益生菌的粘膜粘附凝胶的数据,该凝胶能够确保细菌缓慢释放,以预防和治疗牙周炎。
对一种原始的无水且食品级的粘膜粘附凝胶(AL0005)进行了检测,该凝胶含有乳酸菌和植物干提取物的混合物。
在不同实验模型中,包括模拟唾液或生理溶液,细菌混合物的释放动力学显示出5 - 8小时的显著且稳定的释放。在一项牙周炎小鼠模型研究中,与使用赋形剂的小鼠相比,局部应用富含益生菌菌株的粘膜粘附凝胶显著改善了组织病理学。
总之,结果表明这种粘膜粘附凝胶可用于使牙龈细菌菌群正常化,并改善牙龈疾病的组织病理学。
