RESUMEN

OBJECTIVES@#To compare the effects of different irradiators on the establishment of osteoradionecrosis of jaw model (ORNJ) to explore an ideal modeling method.@*METHODS@#A total of 33 adult SD rats were included and randomly divided into three groups according to the radiation equipment, namely, the blank control (CN, 3 rats), group A (linear accelerator irradiation, 15 rats), and group B (small-animal irradiator irradiation, 15 rats). Groups A and B were irradiated with daily fractions of 7, 8, and 9 Gy for 5 days and further divided into three subgroups as follows: group A@*RESULTS@#At 3 weeks after dental extractions, complete gingival healing was found in the regions of dental extractions in groups A@*CONCLUSIONS@#Small-animal irradiator irradiation is an ideal device for establishing ORNJ model.
