Amitriptyline is a tricyclic antidepressant drug accustomed to treat depressive disorders. It recorded many side effects on different tissues.
To investigate reaction of Albino rats' periodontium after oral administration of Amitriptyline histologically and radiographically.
Fourteen adult male albino rats (150-200 g) were divided into two groups, control and experimental. Rats of experimental group received 10 mg⁄kg⁄day of Amitriptyline hydrochloride by oral gavage for four weeks. Mandibles were prepared for hematoxylin and eosin (H&E) and anti-osteopontin (Anti-OPN) immunohistochemistry staining. Bone mineral density was measured in mandibular alveolar bone. Statistical analysis for Anti-OPN and relative Hounsfield unit value (HU value) was performed using independent-samples -test.
Gingiva of experimental group showed epithelial degeneration with pyknotic nuclei and disintegration in lamina propria. Areas of separation in alveolar bone and degeneration of some regions in cementum were seen with apparent increase in periodontal ligament (PDL) thickness and its detachment from bone and cementum at some regions. Immunohistochemical examination of experimental group showed apparently increased immunopositivity in gingiva, cementocytes, osteocytes, cementum, bone matrices, fibroblasts and PDL fibers when compared to control group. Statistical analysis revealed insignificant difference of Anti-OPN area% in gingiva between both studied groups. While there was statistical significant increase of Anti-OPN area% in the other periodontium tissues and high statistical significant decrease of relative HU value in experimental group when compared to control.
Amitriptyline has destructive effect on periodontal tissues and statistically increases the expression of Anti-OPN in all periodontal tissues except gingiva and decreases bone mineral density.
阿米替林是一种用于治疗抑郁症的三环类抗抑郁药。它对不同组织有许多副作用。
通过组织学和影像学研究白化大鼠口服阿米替林后牙周组织的反应。
将14只成年雄性白化大鼠（150 - 200克）分为两组，即对照组和实验组。实验组大鼠通过口服灌胃给予10毫克/千克/天的盐酸阿米替林，持续四周。制备下颌骨用于苏木精和伊红（H&E）染色以及抗骨桥蛋白（Anti - OPN）免疫组织化学染色。测量下颌牙槽骨的骨密度。使用独立样本t检验对Anti - OPN和相对亨氏单位值（HU值）进行统计分析。
实验组牙龈显示上皮变性，细胞核固缩，固有层崩解。可见牙槽骨分离区域以及牙骨质某些区域的变性，牙周膜（PDL）厚度明显增加，且在某些区域与骨和牙骨质分离。实验组的免疫组织化学检查显示，与对照组相比，牙龈、牙骨质细胞、骨细胞、牙骨质、骨基质、成纤维细胞和PDL纤维中的免疫阳性明显增加。统计分析显示，研究的两组之间牙龈中Anti - OPN面积百分比无显著差异。而与对照组相比，实验组其他牙周组织中Anti - OPN面积百分比有统计学显著增加，相对HU值有高度统计学显著降低。
阿米替林对牙周组织有破坏作用，在统计学上增加除牙龈外所有牙周组织中Anti - OPN的表达，并降低骨密度。
