BACKGROUND: The oral mucosa is relatively vulnerable to pathological processes, and is often affected by autoimmune and malignant diseases. The oral epithelium is normally non-homogeneous, and joins to the connective tissue through interlocking of its downward projections in the form of papillae.
OBJECTIVE: This study aims to conduct a histomorphometric study of the epithelial papillae in patients with oral lichen planus (OLP).
MATERIAL AND METHOD: This study was based on 100 cheek mucosa biopsies from patients with OLP (66 white reticular and 34 atrophic-erosive) (13 males and 87 females, with a mean age of 54.95 +/- 13.64 years). A histological and morphometric evaluation was made, based on imaging analysis with MIP software 4.5 for studying the papillary structure in the patients with OLP.
RESULTS: The mean epithelial thickness was 227.5 +/- 78.5 microm. The different papillary measures--BLS (distance from basal layer to epithelial surface), DPS (distance from dermal papilla top to epithelial surface), DPW (dermal papilla width), and DPD (interdermal papilla distance between two papillae)--yielded no statistically significant differences with respect to age, sex, smoking and clinical form. However, a significant correlation was observed in relation to papilla width and inflammatory infiltrate (P = 0.031).
CONCLUSIONS: The application of this imaging system is useful for measuring variations in epithelial papillary architecture.
