Malocclusion prevalence and orthodontic treatment need in central Anatolian adolescents compared to European and other nations' adolescents

Abstract

Objective: To determine the prevalence of malocclusion and orthodontic treatment need in a large sample of Central Anatolian adolescents and compare them with European-other nations' adolescents. Methods: The sample included 1125 boys and 1204 girls aged between 12 and 16 years with no previous orthodontic treatment history. Occlusal variables examined were molar relationship, overjet, overbite, crowding, midline diastema, posterior crossbite, and scissors bite. The dental health (DHC) and aesthetic components (AC) of the Index of Orthodontic Treatment Need (IOTN) were used as an assessment measure of the need for orthodontic treatment for the total sample. Results: The results indicated a high prevalence of Class I (34.9%) and Class II, Division 1 malocclusions (40.0%). Moreover, increased (18%) and reduced bites (14.%), and increased (25.1%) and reversed overjet (10.%) were present in the sample. Conclusion: Using the DHC of the IOTN, the proportion of subjects estimated to have great and very great treatment need (grades 4 and 5) was 28.%. However, only 16.7% of individuals were in need (grades 8-10) of orthodontic treatment according to the AC.

Evaluation of the Relationship Between Malocclusion and the Periodontal Health, Caries, Socio-economic Status of Children

“…In our study, according to Angle's classification, 55.1% of children had class 1 malocclusion; this result was similar to that of a study performed with 100 children (10-12 years of age) in Turkey (21). However, recent studies have shown that the most common malocclusion in adolescents is class 2 malocclusion in Turkey (22)(23)(24)(25). Nevertheless, when the literature review was done, data on the prevalence of malocclusion are limited (26)(27)(28).…”

“…Malocclusions are the third most prevalent alterations with the third greatest psychosocial impact (9) . According to Bilgic (2014), almost a third of the population evaluated have a very great need of orthodontic treatment (10) . In addition, a study conducted in Chile found that 96.2% of students examined had some kind of malocclusion (9) .…”

Prevalencia de Anomalías Dentomaxilares y Necesidad de Tratamiento en Adolescentes

“…Las ADM constituyen un problema de salud pública ya que junto a caries y enfermedades gingivales/periodontales son las patologías orales más prevalentes tanto en Chile como en el resto del mundo (Bellot-Arcis et al, 2012;Bilgic et al, 2015). Los estudios realizados en nuestro país entregan prevalencias de ADM de 32,4 % en niños y 60 % en adolescentes a nivel regional (Bellot-Arcis et al).…”

“…La etiología es multifactorial, existiendo predisponentes de carácter sistémico, hereditario y congénito. También existen factores locales tales como pérdida prematura de dientes temporales por trauma o caries, restauraciones inadecuadas, malos hábitos y otros (Ahsan et al, 2013).Las ADM constituyen un problema de salud pública ya que junto a caries y enfermedades gingivales/periodontales son las patologías orales más prevalentes tanto en Chile como en el resto del mundo (Bellot-Arcis et al, 2012;Bilgic et al, 2015).
