Objective: To evaluate dental abnormalities and dental maturity in permanent dentition of childhood cancer survivors (CCS) and to compare them with healthy individuals. r> Study design: A retrospective, case-control study, with convenience sampling, evaluated 111 panoramic radiographs (PR) of CCS compared to 111 PR of healthy individuals matched for age and gender. Dental anomalies were
associated with age of cancer diagnosis and type of antineoplastic treatment.
Dental maturity was assessed using the Demirjian method.
Results: A higher prevalence of microdontia, hypodontia and dental root anomalies were present in CCS when compared to healthy individuals (p < 0.05). CCS were the only individuals with 10 or >10 dental anomalies when compared to healthy individuals. Microdontia was the only dental anomaly associated with an age of cancer diagnosis younger than 71 months of age (p < 0.05). Impacted teeth were associated with CCS bryophytes underwent multimodal cancer treatment (p < 0.001). Dental maturity did not present a significant statistical difference between CCS and healthy individuals (p > 0.05).
Conclusions: The CCS had a higher prevalence of dental anomalies without dental maturity alteration when compared to healthy individuals. Age of cancer diagnosis and type of treatment can influence the prevalence of some dental abnormalities.
Keywords: Chemotherapy, radiotherapy, children, dental abnormalities, dental maturity.
