The aim of the study was to assess changes in Transforming Growth Factor- β1 (TGF-β1) levels in gingival crevicular fluid (GCF) and examine correlation of TGF-β1 levels and periodontal parameters: probing pocket depth (PPD) and clinical attachment level (CAL) in sites with chronic periodontitis at various time intervals before and after periodontal surgery.
The effects of non-surgical and surgical therapy on periodontal parameters and GCF TGF-β1 levels in 18 sites affected with chronic periodontitis were assessed upto 6 weeks post conventional flap surgery. GCF was collected and PPD, CAL recorded at Baseline. GCF was collected and PPD, CAL recorded at Pre-surgery and flap surgery performed. GCF was collected from all sites at Two Weeks Post-surgery. GCF was collected and PPD, CAL recorded at Six Weeks Post-surgery. The concentration of TGF-β1 in GCF was determined using a human TGF-β1 enzyme immunometric assay kit.
Mean TGF-β1 concentrations were significantly reduced at Pre-surgery, at Two Weeks Post-surgery and at Six Weeks Post-surgery (p<0.05) when compared to Baseline TGF-β1 values. There was a statistically significant reduction in PPD and gain in CAL following non-surgical and surgical therapy when compared to baseline (p<0.05).
RESULTS indicate that TGF-β1 may play a role in the pathogenesis and diagnosis of periodontal disease and could be considered as a disease predictive biomarker.
本研究的目的是评估龈沟液(GCF)中转化生长因子-β1(TGF-β1)水平的变化,并研究TGF-β1水平与牙周参数之间的相关性,这些参数包括慢性牙周炎患者在牙周手术前后不同时间间隔的探诊深度(PPD)和临床附着水平(CAL)。
评估18个慢性牙周炎患牙部位在常规翻瓣手术后6周内非手术和手术治疗对牙周参数及GCF中TGF-β1水平的影响。在基线时收集GCF并记录PPD、CAL。在术前收集GCF并记录PPD、CAL,然后进行翻瓣手术。在术后两周从所有部位收集GCF。在术后六周收集GCF并记录PPD、CAL。使用人TGF-β1酶免疫分析试剂盒测定GCF中TGF-β1的浓度。
与基线TGF-β1值相比,术前、术后两周和术后六周时TGF-β1的平均浓度显著降低(p<0.05)。与基线相比,非手术和手术治疗后PPD有统计学显著降低,CAL有增加(p<0.05)。
结果表明,TGF-β1可能在牙周疾病的发病机制和诊断中起作用,可被视为一种疾病预测生物标志物。
