The aim of this study was to evaluate and compare histologically the pattern of distribution of platelet and leukocyte concentration, quality of fibrin network, and the aggregation of platelets in the three zones of modified advanced platelet-rich fibrin (A-PRF) buffy coat among uncontrolled type 2 diabetic patients, tobacco smokers, and healthy individuals with chronic periodontitis.
In this cross-sectional cytology study, 180 generalized chronic periodontitis patients (46-55 years) were enrolled - Group 1 (control group): 60 systemically healthy participants, Group 2 (test group): 60 heavy tobacco smokers, and Group 3 (test group): 60 uncontrolled type 2 diabetic patients. Fifteen milliliters of blood was drawn from all study participants. Modified A- PRF membrane was prepared and then processed histologically.
The distribution pattern of platelet and leukocyte concentration in modified (A-PRF) gradually declines from the serum to the red blood cell (RBC) end of a clot in all groups. We have assessed that the serum and middle end of modified (A-PRF) membrane had an increasingly moderate distribution of platelets and leukocytes in both type 2 diabetics and tobacco smokers. RBC end had more of sparse distribution in all the three groups. Healthy individuals exhibited 95% of reversible pattern, whereas tobacco smokers had 78.33% and uncontrolled type 2 diabetic patients had 93.33% of irreversible aggregation pattern of platelets. Loose fibrin network pattern was seen in all the three groups. These observations conclude that tobacco smokers had a high percentage of loose fibrin network with sparse distribution of cells. Males showed more loose fibrin network pattern of modified (A-PRF) membrane than compared to females.
In the present study, it can be concluded that the application of modified (A-PRF) may provide enhanced periodontal healing in uncontrolled type 2 diabetic patients and tobacco smokers; furthermore, females may have better regenerative capacity compared to males.
本研究旨在对未控制的2型糖尿病患者、吸烟者和患有慢性牙周炎的健康个体中改良的高级富血小板纤维蛋白(A-PRF)血沉棕黄层三个区域内血小板和白细胞浓度的分布模式、纤维蛋白网络质量以及血小板聚集情况进行组织学评估和比较。
在这项横断面细胞学研究中,招募了180名广泛性慢性牙周炎患者(46 - 55岁)——第1组(对照组):60名全身健康参与者,第2组(试验组):60名重度吸烟者,第3组(试验组):60名未控制的2型糖尿病患者。从所有研究参与者中抽取15毫升血液。制备改良的A-PRF膜,然后进行组织学处理。
在所有组中,改良(A-PRF)中血小板和白细胞浓度的分布模式从凝块的血清端到红细胞(RBC)端逐渐下降。我们评估发现,改良(A-PRF)膜的血清端和中间端在2型糖尿病患者和吸烟者中血小板和白细胞的分布越来越适中。RBC端在所有三组中分布更为稀疏。健康个体表现出95%的可逆模式,而吸烟者有78.33%,未控制的2型糖尿病患者有93.33%的血小板不可逆聚集模式。在所有三组中均观察到松散的纤维蛋白网络模式。这些观察结果表明,吸烟者中松散纤维蛋白网络的比例较高,细胞分布稀疏。男性改良(A-PRF)膜的松散纤维蛋白网络模式比女性更多。
在本研究中,可以得出结论,改良(A-PRF)的应用可能会促进未控制的2型糖尿病患者和吸烟者的牙周愈合;此外,女性可能比男性具有更好的再生能力。
