Oncological diseases in childhood cause severe pathological alterations of a series of organs and systems, particularly as a consequence of the systemic chemotherapy administered. The purpose of the present communication was to analyze the pathological findings of dental status in children with oncological diseases and in clinically healthy children. The dental status of 15 children, 10 boys and 5 girls at a mean age of 10,67 ±4,03 years (range, 5 to 17 years) with acute leukemia or solid malignant tumors hospitalized in St. Marina University Hospital of Varna in 2017 as well as of 16 clinically healthy children, 10 boys and 6 girls at a mean age of 10,18±3,68 years (range, 5 to 17 years) was examined. Between one and seven decayed, missing or filled teeth were diagnosed in 14 children with malignant diseases but between one and eight lesioned teeth - in 9 clinically healthy children. The difference concerning the mean values of DMFT/dmf-t indexes between the patients and controls was not statistically significant (t=1,59; p>0,10). The necessity to monitor the dental status in the children with oncological diseases who undergo antineoplastic chemotherapy was emphasized.
