Objective: 

Rhabdomyosarcoma is a malignant neoplasm of primitive mesenchyme exhibiting skeletal muscle differentiation. It is the most common soft tissue sarcoma in children. Head and neck region is the most frequently affected area by rhabdomyosarcoma. Radiotherapy and chemotherapy, the treatment method of rhabdomyosarcoma, affects the development of teeth and root formation. In this study, tooth development and root formation anomalies in 2 rhabdomyosarcoma cases are presented.

Methods: 

The 2 cases were a 20-year-old-boy and a 16-year-old-boy who both underwent radiotherapy and chemotherapy because of rhabdomyosarcoma in their head and neck area appealed to our clinic for dental treatments. The patients were 6 and 10 years old respectively when they underwent radiotherapy and chemotherapy. Root genesis anomaly and rhizomicry due to the radiotherapy and chemotherapy were determined with intraoral and extraoral radiological examinations.

Results: 

Dental treatments of the patients were planned with conservative aspects. Strict oral hygiene was ordered to the patients because of the poor conditions of their teeth roots. They were also invited for 6 month routine control and oral hygiene follow-ups.

Conclusions: 

In conclusion, tooth development and root formation abnormalities generated by radiotherapy and chemotherapy; their radiologic appearances seen in rhabdomyosarcoma are emphasized in this study.
