Gamma radiation increases the risk of radiation-related root dental caries

The association between radiation exposure and dental caries has been widely discussed. Several factors contribute to dentition breakdown and radiation-related caries (RRC) development but this condition has previously been associated to be an indirect effect due to radiation-induced salivary gland damage [1,2]. It is well known that radiotherapy of head-and-neck induces damage to the salivary glands, which means that patients with chronic hyposalivation are at high-risk for RRC development and progression [3].
