Background The aim of the present study was to assess the current adoption of cone beam computed tomography ( CBCT ) and panoramic radiography ( PR ) machines across Australia. Methods Information regarding registered CBCT and PR machines was obtained from radiation regulators across Australia. The number of X‐ray machines was correlated with the population size, the number of dentists, and the gross state product ( GSP ) per capita, to determine the best fitting regression model(s). Results In 2014, there were 232 CBCT and 1681 PR machines registered in Australia. Based on absolute counts, Queensland had the largest number of CBCT and PR machines whereas the Northern Territory had the smallest number. However, when based on accessibility in terms of the population size and the number of dentists, the Australian Capital Territory had the most CBCT machines and Western Australia had the most PR machines. The number of X‐ray machines correlated strongly with both the population size and the number of dentists, but not with the GSP per capita. Conclusions In 2014, the ratio of PR to CBCT machines was approximately 7:1. Projected increases in either the population size or the number of dentists could positively impact on the adoption of PR and CBCT machines in Australia.
