Abstract

Amaç: Bu çalışmanın amacı, konjenital maksiller lateral kesici diş eksikliğinin Angle maloklüzyon sınıflarına göre görülme sıklığını değerlendirmek ve bu dental anomalinin farklı maloklüzyon tipleri ile ilişkisini incelemektir.
Gereç ve Yöntem: Bu retrospektif çalışmaya, ortodontik tedavi amacıyla başvuran ve dahil edilme kriterlerini karşılayan toplam 234 birey dâhil edilmiştir. Çalışma grubunda yer alan bireylerin yaş, cinsiyet, Angle maloklüzyon sınıflaması ve konjenital maksiller lateral kesici diş varlığı klinik kayıtlar ve radyografik incelemeler aracılığıyla değerlendirilmiştir. Konjenital maksiller lateral kesici diş eksikliği ile Angle Sınıf I, II ve III maloklüzyon grupları arasındaki ilişki Ki-kare testi ile analiz edilmiştir. İstatistiksel anlamlılık düzeyi p<0,05 olarak kabul edilmiştir.
Bulgular: Çalışmaya dâhil edilen bireylerin yaş ortalaması 14,40±3,35 yıl olup, %64,5’i kadın, %35,5’i erkektir. Konjenital maksiller lateral kesici diş eksikliğinin Angle Sınıf I, II ve III maloklüzyon grupları arasında dağılımı karşılaştırıldığında, gruplar arasında istatistiksel olarak anlamlı bir fark saptanmamıştır (χ²=1,239, p=0,538).
Sonuç: Bu çalışmanın bulguları, konjenital maksiller lateral kesici diş eksikliğinin Angle maloklüzyon sınıfları arasında anlamlı bir farklılık göstermediğini ortaya koymaktadır. Maksiller lateral kesici diş eksikliğinin, belirli bir Angle maloklüzyon sınıfına özgü bir bulgu olmaktan ziyade, farklı maloklüzyon tiplerinde benzer sıklıklarda görülebilen bir dental anomali olduğu düşünülmektedir.

Prevalence Of Congenital Maxillary Lateral Incisor Agenesis According To Angle’s Malocclusion Classification: A Retrospective Study

https://izlik.org/JA59HC46TL

Abstract

Objective: The aim of this study was to evaluate the prevalence of congenital maxillary lateral incisor agenesis according to Angle malocclusion classes and to investigate the association between this dental anomaly and different types of malocclusion.
Materials and Methods: This retrospective study included a total of 234 individuals who applied for orthodontic treatment and met the inclusion criteria. Age, sex, Angle malocclusion classification, and the presence of congenital maxillary lateral incisor agenesis were assessed using clinical records and radiographic examinations. The association between congenital maxillary lateral incisor agenesis and Angle Class I, II, and III malocclusion groups was analyzed using the chi-square test. Statistical significance was set at p<0.05.
Results: The mean age of the participants was 14.40±3.35 years; 64.5% were female and 35.5% were male. When the distribution of congenital maxillary lateral incisor agenesis among Angle Class I, II, and III malocclusion groups was compared, no statistically significant difference was found between the groups (χ²=1.239, p=0.538).
Conclusion: The findings of this study indicate that congenital maxillary lateral incisor agenesis does not differ significantly among Angle malocclusion classes. Rather than being specific to a particular malocclusion type, maxillary lateral incisor agenesis appears to be a dental anomaly that can be observed with similar frequencies across different malocclusion patterns.
