Multiple Tooth Agenesis in Non-syndromic Patient: A Rare Case Report

A 13-year-old female patient came in May 2011 to the Dental Clinics of the Universidad de La Frontera (Temuco, Chile) reporting absence of some teeth. Through a digital panoramic radiograph the existence of multiple agenesis of permanent dentition was revealed. In the radiograph agenesis of tooth 1.4, 1.5, 1.7, 2.5, 2.7, 3.4, 3.5, 4.5 was identified, with a small dimension of maxilla. Also, a slight condylar asymmetry with a small size and a slight stylohyoid ligament ossification was noted in the left side. After this, a foot radiograph was taken to determine if the condition had a relation with an osteopetrosis; however, normal findings were noted. During anamnesis the patient reported she had no trauma history, previous tooth extraction, orthodontic treatment or complications during pregnancy or birth. The patient´s mother informed that there was no history of syndromic or systemic disease.

At general examination no alterations or systemic diseases were identified, with facial symmetry, no palpable lymph nodes and both jaws were normal. Clinically, in the intraoral examination no caries and the absence of the same teeth were observed with tooth rotation of 1.3, 2.3 and 4.3. No presence of periodontal disease was noted.
