Prevalence of Orthodontic Malocclusion and Evaluation Criteria in 7 Geographic Regions of Turkey

Abstract

The aim of this study was to identify the prevalence of malocclusion and orthodontic evaluation criteria in Turkey and determine differences among the 7 regions. Materials and Method: In our research, extra-and intraoral examination of 1023 randomly selected persons from rural and central parts of different regions (500 female subjects and 523 male subjects; mean age = 13.10 6 3.11) were performed. To analyze the data, descriptive statistical methods (mean value, prevalence ratio, standard deviation) were carried out. The significance of regional differences of the evaluation criteria and gender distributions were assessed by means of a v 2 test. Results: Comparison of the classification of malocclusion, crossbite, chin deviation asymmetry, smile line, cleft lip and palate, and profile among the regions showed significant differences (p , 0.05). Class I, II, and III malocclusion was most frequently noted in the Marmara, Aegean, and Central Anatolia regions, respectively. Crossbite was found more frequently on the posterior side (27,4%). Of those with a high smile line, 29.1% were found in the Aegean region. Persons with cleft lip and palate were more frequently identified in the Black Sea, Southeastern Anatolia, and Aegean regions. Midline diastema (6.5%) and openbite (2.9%) in the study group showed no differences between gender and the 7 regions (p. 0.05). Conclusion: Malocclusion and all orthodontic evaluation criteria except midline diastema (p , 0.05) and openbite (p , 0.01) demonstrated statistically significant differences among the 7 regions of Turkey. As a result, we suggest that the distribution of orthodontic anomalies in the different geographic areas should be examined separately to give a more accurate picture of the actual occurrence rate and, therefore, contribute to the development of targeted health policies.

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

“…The included studies had diverse age groups ranging from 0 to 38 years old with a total sample size of 13,271 participants. Most of the studies were conducted only on permanent dentition (Akbulut, 2020 ; Başçiftçi et al, 2002 ; Celikoglu et al, 2010 ; Gelgör et al, 2007 ; Nur et al, 2014 ; Sayin & Türkkahraman, 2004 ; Ugur, 1998 ; Uzuner et al, 2015 ). However, a few of the studies recruited their sample from universities and dental (nonorthodontic) clinics.…”

“…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 .…”

“…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 ).…”

Prevalence and management of natal/neonatal teeth in cleft lip and palate patients

“…[6,7] Cleft lip and palate (CLP) is a common congenital malformation. [8,9] The treatment of patients with CLP teeth emerge after birth (neonatal teeth); the intraoral plate may not fit and modifications of the plate may be required. In some cases, the therapy has to stop and postpone until the teeth has extracted.…”

Clear double layer Bioplast feeding plate for neonates with cleft palate

“…[1] The incidence is approximately 0.6% and more frequently recorded in Black Sea, South Eastern Anatolia, and Aegean region of Turkey. [2] CLP has a complex genetic and environmental etiology associated with dental anomalies. [3,4] Infants with CLP have esthetic and functional problems.…”
