Dental computed tomography (CT) has become a common tool when carrying out dental implants, yet there is little information available on its associated @entity5 risk. The objective of this study was to estimate the lifetime-attributable risk (LAR) of @entity5 incidence that is associated with the radiation dose from dental CT scans and to evaluate the effect of scan position, sex, and age on the @entity5 risk. This retrospective cohort study involved 505 @entity1 who underwent CT scans. The mean effective doses for male and female @entity1 in the maxilla group were 408 and 389   Sv (P = 0.055), respectively, whereas the mean effective doses for male and female @entity1 in the mandible groups were 475 and 450   Sv (P < 0.001), respectively. The LAR for @entity5 incidence after mandible CT scanning varied from 1 in 16,196 for a 30-y-old @entity1 to 1 in 114,680 for a 70-y-old @entity1 . The organ-specific @entity5 risks for @entity259 , other @entity5 , @entity1778 , and @entity2 account for 99% of the LAR. Among @entity1 of all ages, the estimated LAR of a mandible scan was higher than that of a maxilla scan. Furthermore, the LAR for female @entity259 had a peak before age 45 y. The risk for a @entity1 aged 30 y is roughly 8 times higher than that of a @entity1 aged 50 y. After undergoing a dental CT scan, the possible @entity5 risks related to sex and age across various different anatomical regions are not similar. The greatest risk due to a dental CT scan is for a mandible scan when the @entity1 is younger than 45 y. Given the limits of the sample size, machine parameters, and the retrospective nature of this study, the results need to be interpreted within the context of this @entity1 population. Future studies will be of value to corroborate these findings.
