BACKGROUND/PURPOSE: Curcumin has anti-inflammatory impacts and was suggested as an inflammatory disease therapy. This study aimed to investigate the implications of curcumin gel on experimental periodontitis (EPD) and alveolar bone loss in rats.
In this study, twenty-four male Wistar rats were divided equally into four groups: negative control (with no EPD); positive control (EPD induced around lower centrals without treatment); control-treated group: EPD treated with chlorhexidine; and test EPD group treated with curcumin. After 30 days, the serum concentrations of RANKL and IL-1β were measured via ELISA. All animals were sacrificed, and mandibular central incisors with the periodontium were removed. The lingual probing depth and radiographical alveolar bone loss were measured, then samples processed for routine preparation of H&E stained sections and histologically assessed for counting inflammatory cells, osteoclasts, and PDL width.
A significant decrease in the inflammatory cells infiltration, probing depth, and osteoclast numbers with the improvement of PDL associated with a reduction in RANKL and IL-1β serum concentration were seen in both EPD treated groups.
Curcumin is as effective as chlorhexidine in treating experimental periodontitis in rats. It was demonstrated to stop bone destruction related to periodontitis by regulating the RANKL and IL-1β markers level in the blood.
背景/目的:姜黄素具有抗炎作用,被提议用于治疗炎症性疾病。本研究旨在探讨姜黄素凝胶对大鼠实验性牙周炎(EPD)和牙槽骨吸收的影响。
在本研究中,24只雄性Wistar大鼠被平均分为四组:阴性对照组(无EPD);阳性对照组(在下颌中切牙周围诱导EPD但不治疗);对照治疗组:用氯己定治疗EPD;测试EPD组用姜黄素治疗。30天后,通过酶联免疫吸附测定法(ELISA)测量血清中核因子κB受体活化因子配体(RANKL)和白细胞介素-1β(IL-1β)的浓度。处死所有动物,取下带有牙周组织的下颌中切牙。测量舌侧探诊深度和影像学牙槽骨吸收情况,然后对样本进行常规苏木精-伊红(H&E)染色切片制备,并进行组织学评估,以计数炎症细胞、破骨细胞和牙周膜宽度。
在两个EPD治疗组中,均观察到炎症细胞浸润、探诊深度和破骨细胞数量显著减少,同时牙周膜有所改善,且RANKL和IL-1β血清浓度降低。
姜黄素在治疗大鼠实验性牙周炎方面与氯己定一样有效。已证明它可通过调节血液中的RANKL和IL-1β标志物水平来阻止与牙周炎相关的骨质破坏。
