A Case of Completely Impacted Mandibluar Right Second Deciduous Molar With Caries

Abstract

A 6 year 10 month-old boy was refered to the Pedodontic Clinic of Hiroshima University School of Dentistry with the chief complaint of delayed eruption of the mandibular right second deciduous molar. He was born of a normal pregnancy and delivery.
Consultation with a pediatrician revealed that the child's development was normal and that he was very healthy at present.
The principal observations are as follows:
1) An impacted mandibular right second deciduous molar and incisula at gingiva on the alveloar crest of that region were found.
2) Radiographic findings showed that the roots of the mandibular right second deciduous molar were almost formed. A radiolucent lesion due to caries was found at the mesial and occlusal of the dental crown.
3) The roots of the diseased tooth were fractured at extraction. Caries were found at the mesial and occluasl of the dental crown.
