Odontogenic<unk>  Dental panoramic radiograph showing dentigerous<unk> associated with an impacted lower right wisdom tooth in the right mandible (arrowed, appears on the lower left of the image). Relative incidence of odontogenic<unk> . Odontogenic<unk>  have histologic origins in the cells of the dental structures. Some are inflammatory while others are developmental. * Radicular<unk> is the most common (up to two thirds of all<unk> . This inflammatory<unk> originated from a reaction to dental pulp necrosis. * Dentigerous<unk>  the second most prevalent<unk>  is associated with the crown of non-erupted tooth. * Odontogenic keratocyst This lesion may be associated with the Nevoid basal cell carcinoma syndrome. * Buccal bifurcation<unk> which appears in the buccal bifurcation region of the mandibular first molars in the second half of the first decade of life. *Eruption<unk>  a small<unk> in the gingiva as a tooth erupts, forming from the degenerating dental follicle *Primordial<unk>  previous thought to be a unique entity. Most primordial<unk>  have proven to be Keratocystic odontogenic tumors *Orthokeratinized odontogenic<unk>  a variant of the Keratocystic odontogenic tumor *Gingival<unk> of the newborn; an inclusion<unk> from remnants of the dental lamina on a newborn gingiva *Gingival<unk> of the adult; a soft tissue variant of the lateral periodontal<unk> *Lateral periodontal<unk>  a non-inflammatory<unk> (vs a radicular<unk>  on the side of a tooth derived from remanents of the dental lamina *Calcifying odontogenic<unk>  a rare lesion with<unk> c and neoplastic features and significant diversity in presentation, histology and prognosis *Glandular odontogenic<unk> <unk> with respiratory like epithelial lining and the potential for recurrence with characteristics similar to a central variant of low-grade mucoepidermoid carcinoma Developmental/ Non-odontogenic<unk>  There are several development<unk>  of the head and neck most of which form in the soft tissues rather than the bone. There are also several<unk> , previously thought to arise from epithelial remanents trapped in embryonic lines of fusion, most of which are now believed to be odontogenic in origin or have an unknown cause. Their names are included for the sake of completeness. Developmental<unk>  *Nasopalatine duct<unk>  the most common development jaw<unk>  appears only in the mid-line of the maxilla. Developmental<unk>  of the soft tissues around the jaws *Palatal<unk>  of the newborn (Epstein's pearls) *Nasolabial<unk> (nasoalveolar<unk>  *Epidermoid<unk> of the skin *Dermoid<unk> *Thyroglossal duct<unk> *Branchial cleft<unk> (Cervical lymphoepitelial<unk>  *Oral lymphoepithelial<unk> Developmental<unk>  of questionable cause *Globulomaxillary<unk> *Median palatal<unk> *Median mandibular<unk>
