Prevalence of dental agenesis in patients submitted to orthodontic treatment: A radiographic study
Journal Title: Revista Uningá - Year 2021, Vol 58, Issue 1
Abstract
The most common developmental dental anomaly in human dentition is the dental agenesis which can happen in the deciduous and permanent dentitions. The most affected teeth by the agenesis are the third molars, premolars and upper lateral incisors. It is commonly associated with other types of anomalies such as microdontia, ectopias and delayed dental development. Therefore, the dental surgeon must pay attention to the development of other anomalies so that the diagnosis and orthodontic interception can happen in the appropriate moment. An evaluation of panoramic radiographs and medical records of 50 patients, randomly selected, aged between 6 and 20 years, of both genders, excluding syndromic patients, who sought orthodontic treatment in the Postgraduate Course in Orthodontics at Volta Redonda University Center, was carried out. The objective of this observational study was to evaluate the presence of agenesis of some permanent dental element, excluding the third molars, to identify the most affected teeth, as well as the association with other dental anomalies. Evaluating the results, it was observed that 9 patients had dental agenesis (18%), with a higher prevalence in females (55.6%). The most affected teeth were the upper lateral incisors, followed by the lower second premolars and second upper premolars. The presence of other dental anomalies associated with agenesis was identified in 4 patients (44.4%), with a predominance in females (75%), which were the delayed tooth development, conoid shape, ectopia in positioning and root laceration. It was concluded that in the studied sample there was a high prevalence of dental agenesis, having as reference other studies with orthodontic patients.
