Abstract

Introduction: Rete ridges are epithelial extensions toward the underlying connective tissue in skinand mucous membranes. Given the advances in tissue engineering in recent years, rete ridges have become the center of attention. Therefore, the aim of the presentstudy was to evaluate the shape of rete ridges (RR) in different Oral mucosal lesionsfor possible histological differential diagnosis and their possible relation withinflammation for better understanding of their histogenesis. Materials& Methods: This retrospective, descriptive, analytical study was performed on 154 oral lesionsclassified as epithelial (E), connective tissue (Ct) and mucocutaneous (Mc) lesions. RRs were evaluated under a light microscope at ×100 as flat or hyperplastic. Inflammation at Epithelium‒ connective tissue interface was evaluated in 5 consecutivehigh-power fields (×400). Data were analyzed with chi-squared test (α = 0. 05). Results: In 87%, 80% and 58% of Ct, E and Mc lesions, hyperplastic RRs were seen, respectively (p value < 0. 001). RR forms Mc lesions were significantly different fromthe two other groups (p value < 0. 001). However, no statistically significant differencewas observed in RRs between E and CT lesions (p value = 0. 48). Hyperplastic RRs inreactive Ct lesions was seen more frequently than other Ct lesions; however, Inflammation in different intensities was not related to RR shape (p value < 0. 05). Conclusion: The results of the present study showed that rete ridges in Oral mucosal lesions werehyperplastic predominantly, indicating that Inflammation is not the reason for thehyperplastic nature of rete ridges. Further studies are recommended.
