Odontogenic tumors (OT) arise from remnants of the embryonic tissues destined to develop into teeth and associated structures. They originate from remnants of odontogenic epithelium (rests of Malassez and rests of Serres located within the periodontal ligament stroma and gingiva, respectively), odontogenic mesenchyme, or a combination of the cellular elements that comprise the tooth-forming apparatus. Clinical behavior ranges from hamartoma-like proliferations to benign and invasive neoplasms.

Reactive lesions are non-neoplastic gingival enlargements that are commonly grouped under the previously noted nondescript classification of epulides. The term ‘epulis’ (singular) has no specific histopathologic connotation and is a clinical designation for any localized, exophytic swelling on the gingiva. Reactive lesions include focal fibrous hyperplasia, pyogenic granuloma, peripheral giant cell granuloma and reactive exostosis. Marginal excision of these lesions, without inclusion of adjacent normal tissue, is generally sufficient, as local recurrence is uncommon.
