Introduction: Odontomas are tumors of odontogenic origin. They represent on average 70% of all odontogenic tumors found. Early diagnosis and treatment prevent the loss of tissue element, tooth impaction, bone malformations, and displacement of bone structures, differentiating their types through panoramic radiographic images. Objective: To carry out a concise systematic review of the characteristics of odontomas, differentiating their types through panoramic radiographic images. Methods: The research was carried out from May 2021 to June 2021 and developed based on Scopus, PubMed, Science Direct, Scielo, and Google Scholar, following the Systematic Review-PRISMA rules. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results: A total of 84 articles were found. A total of 36 articles were evaluated in full and 17 were included and evaluated in the present study. A total of 3 Studies with a High Risk of Bias and 1 Study with Uncertain Risk. Radiographic examination is extremely important for the study and diagnosis of odontomas. Odontomas present a characteristic radiographic appearance. In complex odontomas, radiopacity is not specifically determined, showing itself as an irregular and disorganized mass surrounded by a narrow radiolucent zone. In the composite type, the radiographic image is pathognomonic. In the radiopaque image, dozens of denticles simulate small teeth surrounded by a thin radiolucent area. Composite odontoma, on the other hand, consists of the same calcified structures arranged in an orderly and related manner, similar to normal teeth contained in a fibrous capsule. The differential diagnosis of complex odontoma includes osteomas and condensing osteitis. Conclusion: Radiographic and/or tomographic examination is the best way to obtain an accurate diagnosis, precisely delimiting the lesion and nearby and involved structures.
