AIM: To study the incidence of coronoid foramen and accessory lateral canal in the opg with normal digital techniques. MATERIALS AND METHODS: Randomly selected 100 opgs of all age groups were collected from the department of radiology in a private dental college and hospital and examined for bilateral coronoid foramen, confirmed patients were advised for CT. RESULTS: There were no bilateral coronoid foramen were not found with normal digital opg protocols. DISCUSSION: Thereby, the possible hypothesis as understood from the exhaustive comparative morphology and the available literature by the author suggests, that the variation is a possible reflection of what is found in other mammals, one such hypothesis is the phylogenetic correlation. CONCLUSION: From this study it is evident that there is no incidence of bilateral coronoid foramen in the digital opg.
