ABSTRACT:
Tooth agenesis is an orthodontic abnormality affecting the number of teeth. This leads to various types of malocclusion, disturbance in the masticatory function and poor esthetics.
This survey includes 1510 orthodontic patients treated by us. Two hundred and seven (13.71%) of all of the patients have been diagnosed with tooth agenesis. One hundred thirty-seven (8.87%) of the treated patients have tooth agenesis, while 31 (2.05% of all of the patients and 23.13% of the patients with tooth agenesis) have tooth agenesis also in the third molars. In general 207 of the patients have tooth agenesis of 637 teeth. In 104 patients there are 348 absent germs of third molars. Chiefly the tooth agenesis affects one or two teeth. Fifty three patients 39.55% are with one missing tooth and 50 of them – 37.31% are with two missing teeth. It affects most often lower second premolars, followed up by the upper lateral incisors, the next group is the group of the upper second premolars. In 5 of our patients we diagnosed and treated tooth agenesis of the canines, in two of those patients the tooth agenesis of the canines was bilateral. This is a very rare problem that creates to serious occlusal dysfunctions. We found out that the ratio of distribution among the genders is at higher level for the female patients (9.70%) compared to the male patients (7.51%).
Knowing the rate of the problem among a certain nation is very important for its early diagnosis and considering the optimal treatment plan.
