Few cases of radiation-induced damage to the teeth and jaws, have been reported in the literature. Radiation therapy plays an important role in the treatment of patients affected with head and neck cancer. In spite of its recognized benefits in the treatment of malignant tumors, radiation therapy has several side-effects in the head and neck region. This paper highlights a case report where hypoplasia of the mandible, trismus and stunted permanent teeth roots were observed in an 18-year-old patient who was diagnosed with parameningeal rhabdomyosarcoma—embryonal type group III at the age of 5 years. He had received radiation therapy of 50 Gy to the nasopharynx for about 1 year and was reviewed for a period of 11 years. Full mouth periapical radiographs and panoramic radiograph revealed hypoplasia of the mandible and generalized hypoplasia of the roots of the permanent teeth.
