Acute lymphoblastic leukemia: dental health of children in maintenance therapy.

The dental health of 41 children aged 4-16 years who were in maintenance therapy from acute lymphoblastic leukemia (ALL) was examined in relation to the period of time in maintenance. There was no significant difference in dental experience and salivary flow rate between the control group and patients with leukemia. Performed treatment index (PTI) and required treatment index (RTI) scores reflected that children, who were in maintenance therapy had insufficient dental care and needed more dental treatments. A statistically significant difference in salivary pH was found between the children, who were in maintenance therapy for 12-24 months and less than 12 months and also the control group; but the pH scores of all groups were observed in normal limits.
