Before table 4-19 modeling, after modeling, treat 1 month, the level change of inflammatory factor in level in gingival sulcus fluid after 3 months
(3) histology and Immunohistochemical detection result: Microscopic observation after treating 1 month, even mending sustained-release gel group can See that bone matrix is formed, bone Mineral nodules, but also show a small amount of osteoclast and be present in bone lacuna;Pike change group, Lan Ranqu At inflammatory cell place, alleviate than inflammation with after matched group and modeling, but have no the formation of bone matrix;Blank gel group is visible Substantial amounts of inflammatory cell infiltration, periodontal membrane fiber arrangement disorder, alveolar bone has destruction in various degree, and osteoclast is positioned at bone and inhales Receive in lacuna (Figure 16).
Microscopic observation after local treatment 3 months, even mends sustained-release gel group thickness of periodontal membrane uniform, have more bone matrix and Bone Mineral nodules is formed, and has no that obvious osteoclast exists;Pike change group inflammation alleviates after relatively treating one month, rarely seen epithelium Slightly hypertrophy, inflammatory cell significantly reduces, but has not yet to see obvious new bone formation;Seen from Blank gel group furcation area significantly Cranial defect, periodontal membrane forfeiture, epithelial proliferation, elongation, substantial amounts of inflammatory cell infiltration.
After local is treated 1 month, IL-8, IL-1 β and PGE2 level all reduces with comparing after modeling, has significant difference (P < 0.05), there is significant difference with matched group than pike change group, even benefit sustained-release gel group, minimum with pike change level, group is described Beautiful anti-inflammatory effects difficult to understand is best, secondly for even mending sustained-release gel group.After local treatment 3 months, even mend sustained-release gel group and pike change Between group, difference is inconspicuous, not statistically significant, and the same pike change of long-term anti-inflammatory effects of sustained-release gel group is mended by the company of explanation.TNF-α、 IL-1 β, IL-8 immunohistochemical staining result becomes strong positive to express after showing modeling, after local is treated 1 month, respectively uses after 3 months Medicine group compares expression and reduces with matched group, the most weak even to mend the expression of sustained-release gel group.
