PREFACEOdontogenic lesions are a variety of lesions with potential shared aetiologies but various therapeutic approaches. The odontogenic lesions ameloblastoma, dentigerous cyst, and odontogenic keratocyst are prone to malignant transformation or local invasion. Uncertain molecular mechanisms underlie the emergence of these lesions. Oncogenes or tumour suppressor genes may be dysregulated in certain lesions, according to some studies. P53 gene down-regulation has been documented in AB, DC, and OKC. A number of long non-coding RNAs, including KIAA0125 and ENST00000512916, have also been...
