The mandibular second bicuspid is sometimes missing. Next to the third molar, this tooth is most frequently missing in the human dentition.
The patient was a 3 years 11 months old male at the first visit. The chief complaint was the caries treatment. All the cavities were treated and the patient was sent to recall system at our department.
The rootcanal of the right lower primary molar was infected due to caries after 3 years. The mandibular second bicuspid was missing according to radiographic examination. This tooth needed to be treated endodontically. The endodontic treatment was successful.
The patient came to our department suddenly after 9 years and 5 months, because this tooth moved extremely. Radiographic examination revealed the development of second bicuspid crown.
This paper deals with the difficulty of the diagnosis in the patient whose mandibular second bicuspid was considered to be missing.
