This study evaluates the healing of the rabbit temporomandibular joint (TMJ) following discectomy in four groups of animals fed a ground diet for 3 consecutive months (group 1), a ground diet for 1 month followed by 2 months of a coarse diet (group 2), a ground diet for 6 consecutive months (group 3), or a ground diet for 3 months followed by a coarse diet for 3 months (group 4), in order to evaluate the effects of changing the diet texture following discectomy. After 3 and 6 months, histologic evaluation demonstrated that 1) an early hyperplastic response in the fibrocartilage regressed in the later period regardless of diet, and 2) switching the ground diet to a hard diet caused degenerative scores to increase after both 1 and 3 months.
本研究评估了四组动物在椎间盘切除术后兔颞下颌关节（TMJ）的愈合情况。这四组动物分别连续3个月喂食磨碎的食物（第1组）、先喂食1个月磨碎的食物，然后再喂食2个月粗糙食物（第2组）、连续6个月喂食磨碎的食物（第3组）、或先喂食3个月磨碎的食物，然后再喂食3个月粗糙食物（第4组），以评估椎间盘切除术后改变食物质地的影响。3个月和6个月后，组织学评估表明：1）无论饮食如何，纤维软骨早期的增生反应在后期都会消退；2）将磨碎的食物换成硬质食物后，在1个月和3个月时退变评分均增加。
