Sažetak
Hypodontia is characterized by the congenital absence of one or more teeth. It is one of the most common developmental anomalies. In the permanent dentition, the most frequently missing teeth are third molars, second premolars, upper lateral incisors and lower central incisors. Agenesis of permanent canines is extremely rare. According to the literature, the prevalence of permanent canine agenesis varies between 0.01% and 0.86% and is more common in the maxilla than the mandible. Studies have shown that females are more affected by this congenital anomaly than males. A case of canine agenesis was observed in an 11 year old Croatian girl who came to the School of Dental Medicine for a dental exam because of diastema mediana. The patient had neither systemic diseases nor hereditary disorders which could potentially influence tooth formation or eruption. An intraoral examination revealed a mixed dentition and a persistent frenulum tectolabiale. An orthopantomograph showed agenesis of the maxillary permanent canines and permanent second molars at a stage of gingival emergence. The first signs of crypt formation were visible only for the right mandibular third molar. A family history of congenitally missing teeth was negative. After the patient underwent a frenulectomy, she had a regular check-up at age 17. At this time, the patient still had retained primary canines. Diastema mediana was present but reduced to 0.5 mm. A control orthopantomograph revealed the presence of all four third molars germs. This unusual case of isolated maxillary canine agenesis in a female patient along with earlier research that found this anomaly to be twice as common in females indicates canine hypodontia may represent a sexually dimorphic characteristic of the human dentition.
