This report details a case of 8-year-old girl showing failure of odontogenesis after
chemo-radiation therapy for the rhabdomyosarcoma at the age of 4.
The observed results were as follows :
1. Past history revealed that she had received for a total radiation dose of 4430cGy, 29
fractions in 6 weeks and chemotherapy with vincristine, actinomycin D and cytoxan,
followed as maintenance phase for 2 years.
2. The patient was symptom-free and appointed for the treatment of multiple dental
caries.
3. Oral examination showed hypoplastic enamel on whole erupted permanent teeth and
showed retarded eruption.
4. Conventional radiograms showed failure of root development including abrupt
cessation of root formation and root agenesis. and microdontia, missing teeth. irregular
enamel, dislocation of the impacted teeth. Additional finding showed good healing bone
pattern on the left mandibular ramus and angle area.
5. Cephalometric analysis revealed failure of bite raising due to incomplete eruption of
all the first molars and made it possible to suspect entrapped mandibular growth and
then Class ¥± tendency growth.
6. There was correlation between the time of chemo-radiation therapy and the damage
of the teeth.
