AB  - OBJECTIVES: The use of dental cone-beam CT (CBCT) has increased in recent years. 
      We aimed to calculate the organ and effective doses in dental CBCT using Monte 
      Carlo simulation (MCS) and to correlate the effective dose with the dose-length 
      product (DLP), which is a radiation dose index. METHODS: Organ and effective 
      doses were calculated by MCS using the adult male and female reference phantoms 
      of the International Commission on Radiological Protection publication 110 in a 
      half-rotation scan of the CBCT scanner Veraviewepocs 3Df. The simulations were 
      performed by setting nine protocols in combination with the field-of-view (FOV) 
      and imaging region. In addition, DLPs were calculated by MCS using the virtual CT 
      Dose Index (CTDI) and CBCT phantoms, with the same protocol. RESULTS: The 
      effective doses were 55 and 195 muSv at the minimum FOV of Phi40 x H40 mm and 
      maximum FOV of Phi 80 x H80 mm, respectively. The organs with the major 
      contribution to the effective dose were the red bone marrow (11.0‒12.8%), thyroid 
      gland (4.0‒12.7%), salivary gland (21.8‒33.2%), and remaining tissues 
      (35.1‒45.7%). Positive correlations were obtained between the effective dose and 
      calculated DLP using the CTDI and CBCT phantoms. CONCLUSIONS: Organ and effective 
      doses for each protocol of dental CBCT could be estimated using MCS. There was a 
      positive correlation between the effective dose and DLP, suggesting that DLP can 
      be used to estimate the effective dose of CBCT.
