Cytomorphometry is the analysis of the morphometry of exfoliated cells. Studies on exfoliated gingival epithelial cells in chronic periodontitis were not evident on the literature search. In the backdrop of this information, we were inspired to conduct a cytomorphometric study.
The aim of the study is to correlate the nuclear area (NA), cytoplasm area (CA), and the nuclear: cytoplasm ratio (N/C) in the gingival cells of healthy individuals, patients with chronic periodontitis, and chronic periodontitis patients who are tobacco chewers.
Ninety subjects, aged 35-45 years, were categorized into three equal groups of 30 each. Group I had individuals with healthy gingiva, Group II patients with chronic periodontitis without any deleterious habits, while Group III patients with chronic periodontitis and tobacco chewing habit. Exfoliated gingival cells were stained with Papanicolaou stain. Analysis of cells was done using binocular light microscope under ×40 and i-progress image analyzer software.
There was statistically significant increase in CA in all the groups, but NA and N/C ratio did not show any statistical significant difference. When Group II was compared with Group III, we found significant correlation of CA with pocket probing depth and clinical attachment loss (CAL) in Group II. Similarly, we also found a correlation of CA and N/C with pocket depth and CA with CAL in Group III.
The results suggest that molecular level changes occur in the cells. Cytomorphometry can be used to analyze the cellular changes in chronic periodontitis patients even before clinical signs manifest. Hence, it can be used as an investigative tool.
细胞形态计量学是对脱落细胞的形态测量进行分析。在文献检索中未发现关于慢性牙周炎患者脱落牙龈上皮细胞的研究。基于此信息,我们受到启发开展了一项细胞形态计量学研究。
本研究的目的是比较健康个体、慢性牙周炎患者以及有咀嚼烟草习惯的慢性牙周炎患者牙龈细胞中的核面积(NA)、细胞质面积(CA)和核质比(N/C)。
90名年龄在35 - 45岁的受试者被平均分为三组,每组30人。第一组为牙龈健康个体,第二组为无任何有害习惯的慢性牙周炎患者,第三组为有咀嚼烟草习惯的慢性牙周炎患者。脱落的牙龈细胞用巴氏染色法染色。使用双目光学显微镜在×40倍下及i - progress图像分析软件对细胞进行分析。
所有组的CA均有统计学意义的增加,但NA和N/C比值未显示出任何统计学显著差异。将第二组与第三组进行比较时,我们发现第二组中CA与牙周袋探诊深度和临床附着丧失(CAL)存在显著相关性。同样,我们在第三组中也发现CA和N/C与牙周袋深度以及CA与CAL之间存在相关性。
结果表明细胞发生了分子水平的变化。细胞形态计量学可用于在慢性牙周炎患者临床症状出现之前分析细胞变化。因此,它可作为一种研究工具。
