Distribution of sagittal occlusal relationships in different stages of dentition

Abstract

The aim of this study was to assess the distribution of sagittal occlusal relationships in different dentition periods in a Turkish sample group. In total, 1,110 patients (561 females, 549 males) aged 4.6-23 years were randomly chosen after intraoral clinical examination. The subjects were classified according to their sagittal occlusal relationships and four dentition stages -deciduous, early mixed, late mixed, and permanent dentition. The statistical significance of the occurrence of malocclusion types in dentition stages was evaluated by Chi-square and Fischer's exact tests. Class I malocclusion was observed at the highest rate in all dentition stages. Class III malocclusion was observed at the highest rate in the permanent dentition, whereas Class II malocclusion was observed at the highest rate in the late mixed dentition. The rates of Class I, II, and III malocclusions were similar in males and females. Our study reveals that the prevalence of malocclusion and need for orthodontic treatment has increased in the population towards the permanent dentition.

Prevalence of malocclusion in Turkish children and adolescents: A systematic review and meta‐analysis

“…Based on the STORB appraisal tool (Table 2 ), the majority of studies had a low risk of bias. However, one study showed a moderate risk of bias, (Akbulut, 2020 ) and two studies showed a high risk of bias (Kaygisiz et al, 2015 ; Sari et al, 2003 ).…”

“…The overall prevalence of malocclusions in the 10 studies reported the dental relations were 56% for class I, 31% for class II, and 11% for class III malocclusion (Akbulut, 2020 ; Başçiftçi et al, 2002 ; Celikoglu et al, 2010 ; Gelgör et al, 2007 ; Kaygisiz et al, 2015 ; Nur et al, 2014 ; Sari et al, 2003 ; Sayin & Türkkahraman, 2004 ; Uzuner et al, 2015 ; Yilmaz et al, 2006 ). Furthermore, the remaining 2% were allocated to normal and other types of occlusions such as class IV malocclusion (Celikoglu et al, 2010 ; Gelgör et al, 2007 ; Nur et al, 2014 ; Uzuner et al, 2015 ).…”

“…Additional information is mentioned in Table 4 . Performing the relative risk meta‐analysis demonstrated that there were no significant differences in malocclusion prevalence between the two genders (Table 5 ) (Akbulut, 2020 ; Başçiftçi et al, 2002 ; Celikoglu et al, 2010 ; Gelgör et al, 2007 ; Kaygisiz et al, 2015 ; Nur et al, 2014 ). The only study which determined the molar relation of primary dentition showed that 88% of individuals had flash terminal moral relation, 7% had a distal step, and 5% had a mesial step molar relation (Sayin & Türkkahraman, 2004 ).…”

“…Toplumumuzda Sınıf III maloklüzyonların görülme prevalansı %11.7 olarak belirtilmektedir. 1 Büyüme gelişim dönemindeki maksiller yetersizlikle karakterize Sınıf III malokluzyona sahip bireylerin tedavisinde, maksillanın ileri yönde hareketi ve maksillo-mandibular ilişkinin düzeltilmesine yönelik farklı ağız içi ankraj üniteleriyle birlikte yüz maskesi sıklıkla uygulanmaktadır. [2][3][4][5] Bionatör III, Frankel III, Sınıf III Twin-Blok, ağız içi çift plak gibi apareylerin tek başına veya yüz maskesi ile birlikte uygulanması tedavi seçenekleri arasında yer almaktadır.…”
