Description
Summary:<b>Background:</b> Epithelial integrity is important for maintenance of periodontal health. It is not fully known if non-surgical periodontal therapy is capable of recreating the epithelial barrier in its functional state. <b> Patients and Methods:</b> Sixty-five patients (31 males and 34 females) were included in the study. They were divided into group A (healthy gingiva 16 patients), group B (gingivitis 17 patients), group C (periodontitis 17 patients), and group D (post-treatment 15 patients). Gingival samples were collected and immunohistochemical study was done using E-cadherin and CD1a antibody. Statistical analysis was done using analysis of variance (ANOVA), followed by Tukey-Kramer multiple comparison test for CD1a and Tukey&#x2032;s highly significant difference (HSD) test for E-cadherin. <b> Result:</b> There was a statistically significant difference (<i>P</i> &lt; 0.001) in the expression of E-cadherin between healthy (1.846&#177;0.555), gingivitis (1.100&#177;0.994), and periodontitis group (0.700&#177;0.483). Similarly, there was a statistically significant difference (<i>P</i> &lt; 0.001) in the expression of CD1a between healthy (75.70&#177;3.09), gingivitis (42.53&#177;3.09), and periodontitis group (29.07&#177;3.08). However, the expression of E-cadherin (1.242&#177;0.653) and CD1a in post-treatment samples (52.18&#177;2.90) was lower with no statistically significant difference when compared to health. <b>Discussion: </b>The significant reduction in E-cadherin and CD1a levels in periodontal disease when compared to health could possibly be a result of invasion by the periodontopathogens and its subsequent sequel. Although, the post-treatment samples showed significant improvement when compared to disease, the reduction in E-cadherin and CD1a levels when compared to gingival health suggests that the epithelial barrier was not yet fully established in its functional state.</b>
