Failure of eruption of permanent tooth: a case report
The present case has been reported in the International Journal of Applied and Basic Medical Research. A 16 year old female patient appeared for the evaluation and treatment with a history of retained primary teeth. The patient's medical history revealed that Her mother had an uneventful pregnancy and was delivered at 38 weeks by normal delivery.

A panoramic radiograph revealed the presence of retained primary teeth and development of few permanent teeth. At that time, an extensive evaluation showed no abnormalities in thyroid function, and calcium, phosphorus, and alkaline phosphatase levels were within the normal range for a growing age. Bone age corresponded to chronologic age.

The patient has continued to grow normally throughout childhood; for her age, she is above normal in height and weight. The general health of the patient has been excellent, with no allergies or hospitalizations. She has a male sibling with no dental problems, and there is a negative family history of dental anomalies. Physical evaluation revealed her to be a well-proportioned girl with no craniofacial, dermal, or skeletal morphologies.

She displayed age-appropriate development, and no abnormalities were noted in her hair, skin, or nails. On initial examination at 16 years of age, it was noted that 16 of her permanent teeth had erupted; these teeth displayed normal size, shape, and quality of enamel; 14 of her primary teeth are retained.

Radiographically, retained primary teeth were present, and few permanent teeth impacted. The nonerupted teeth were covered with bone and had well-circumscribed follicles. However, continued root development of the permanent teeth was noted, without progress toward the alveolar crest.

The patient was evaluated extensively at the initial visit and subsequent visits. All laboratory values were within the normal range, including parathyroid, thyroid, and growth hormone levels and calcium, phosphorus, and vitamin D levels. Bone age at 16 years corresponded to chronologic age. In the absence of any other signs, the diagnosis was primary retention of the permanent teeth.
