Abstract: Background. There is lack of data related to dental occlusion among children cured from cancer. The aim of our study was to compare the prevalence of malocclusion in cancer survivors and in healthy peers. Methods. A cross-sectional study was conducted on 225 children aged between 4 and 18 years, including 75 cancer survivors, and 150 sex and age-matched controls. All patients were orthodontically examined and malocclusion traits were recorded. In the cancer group, 75 panoramic radiographs were used to evaluate the prevalence of dental anomalies and dental age using the Demirjian scale. Data were analyzed by univariate statistical analysis with p -values p < 0.05 considered as statistically significant. Results. Malocclusion was found in 49 (65.33%) cancer survivors and 99 (65.56%) controls ( p > 0.05). The cancer group demonstrated significantly higher likelihood of crossbite ( p < 0.01) and malalignment of teeth ( p = 0.031). The healthy controls were more likely to demonstrate open bite ( p = 0.038). Cancer patients with posterior crossbite ( p = 0.023) or dental malalignment had a more advanced dental age ( p = 0.022). Survivors with crossbite had more teeth with short roots ( p = 0.016). Those who were older when they started their cancer therapy were more likely to suffer from tooth disturbances ( p = 0.019). Conclusion. Oncological treatment can alter the development of occlusion in cancer patients.
