Prevalence of developmental dental anomalies in Serbian orthodontic patients

Abstract

Introduction/Objective The aim of this study was to evaluate the prevalence of developmental dental anomalies (DDA) in Serbian orthodontic patients. Methods The sample was composed of 1,001 panoramic radiographs of orthodontic patients, older than seven years, taken as a part of the initial diagnostic procedure at the Clinic of Orthodontics, School of Dental medicine in Belgrade. The DDA that could be diagnosed accurately on panoramic X-rays were documented. Descriptive analysis was used to determine prevalence and sex distribution of DDA. The Pearson χ 2 test and Fisher's exact test were used to compare number of affected teeth in males and females (level of significance was 95%). Results The prevalence of DDA in Serbian orthodontic patients was 34.8% (15.5% males and 19.3% females). Impactions were present in 16.5%, hypodontia in 12.9%, hyperdontia in 4.4%, microdontia in 2.9%, macrodontia in 1.8% and transposition in 0.8% of patients. Maxillary canines were the most frequently impacted teeth. Maxillary second molars were more prone to impaction in females (p < 0.05). Impacted incisors were more prevalent in maxilla, premolars, and second molars in mandible. The most commonly missing teeth were upper left second premolars. Mesiodens was the most frequently found supernumerary tooth. Conclusion We reported а high a rate of DDA in Serbian orthodontic patients, more in females than males. The most frequently observed DDA were impaction, tooth agenesis, hyperdontia, microdontia, macrodontia, and transposition. All investigated DDA were more frequently present in females, except hyperdontia. Current findings could offer а foundation for epidemiological studies on DDA prevalence.

Pronóstico de caninos impactados según su posición en el maxilar superior mediante diferentes análisis radiográficos

“…Son del 1 a 3% en la población general 15 . Sin embargo, en un estudio realizado en Serbia, los caninos impactados fueron los más prevalentes, con un 34,8% de anomalías dentales, y la más frecuente fue la impactación, especialmente del canino maxilar 16 . El resultado es similar al de un estudio realizado en Italia, en el que la anomalía más frecuente fue el desplazamiento de caninos en un 7,5%, en una muestra de 5000 sujetos 17 .…”

“…Al comparar la frecuencia encontrada por sexo, el doble de los casos fueron mujeres, lo que coincide con otros estudios, como el realizado en Kosovo, en el que el 64% fueron en mujeres 15 ; en Serbia, en el cual fue significativamente mayor en mujeres 16 , y también en adolescentes colombianos 22 . Pero esto podría deberse en nuestro medio a que las mujeres acuden más al odontólogo, tienen tendencia a realizarse estudios y el tratamiento correspondiente.…”

“…Quite a large number of studies on the prevalence of malocclusions in different populations were published. However, information on the prevalence of malocclusion in the Serbian population is scarce [5,59].…”

The accuracy of Belgrade Age Formula method for dental age estimation in Montenegrin children aged 10–12 years

“…The most used approaches for determining dental age are based on the sequence in which permanent teeth emergence and radiographic evaluation of the degree of the crown and roots mineralization of permanent teeth [11,12]. The variability of tooth development and emergence is influenced by gene mutations, generalized and/or localized insults [13,14].…”
