THE CHANGES IN THE ORAL MUCOSA CAUSED BY CONTACT WITH RESTORATIVE MATERIALS (Abstract): The clinical interpretation of mucosal changes upon contact with restorative materials still raises many questions, mainly due to the questionable biological qualities of these materials. Material and method: The study sample comprised 32 cases. The morpho-pathological examination involved analyzing the structural composition of mucosal material obtained from the oral mucosa. The biopsy fragments were processed for standard microscopic examination. Results and discussion: The number of cellular layers in the spinous layer was altered, with flattened cells and small intercellular spaces, often observed in long-standing restorations that compress the underlying mucosa. The histopathological image of the mucosa in contact with non-precious metal alloys veneered with ceramic showed minimal changes in both the epithelium and the connective tissue. Traumatic factors led to alterations in epithelial keratinization (parakeratinization, hyperkeratinization), resulting in thickening or, conversely, thinning of the epithelium. Conclusions: The anatomopathological examination highlighted morphological aspects characteristic of the etiological factor.
