Abstract

Purpose

This research is designed to obtain a better understanding and provide more insight of this phenomenon through evaluating the prevalence of congenital absence of maxillary lateral incisors in a Syrian population.

Methods

The method involved clinical examination of 8000 school children with an equal number of males and females (age range 12–15 years) to identify students only affected by bilateral or unilateral congenital absence of maxillary lateral incisors. Agenesis was determined based on radiological evidence.

Results

The results of this study showed that the prevalence of isolated maxillary lateral incisors agenesis was 1.15%. In the sample studied, 66.3% of the patients were female and 33.7% were male (p < 0.05). Absence was bilateral in 47.8% of patients and unilateral in 52.2%. Of the unilateral cases, 48% occurred on the right side and 52% on the left side, and the contralateral maxillary incisor was found to be microdont in 43.75%, right lateral in 47.6%, and left lateral in 52.4%.

Conclusion

The results of this study allow the conclusion that the prevalence of isolated maxillary lateral incisors agenesis in a Syrian population is within the average range with regard to other populations. A significant familial component to the etiology of maxillary lateral incisors agenesis was found.

Zusammenfassug

Zielsetzung

Ziele der Studie waren ein besseres Verständnis und ein vertiefter Einblick in das Phänomen nicht angelegter lateraler oberer Schneidezähne in einem syrischen Probandenkollektiv.

Methoden

Die Methode umfasste die klinische Untersuchung von 8000 Schülerinnen und Schülern (m:w = 1:1) der Altersgruppe 12–15 Jahre, um Kinder mit isolierten uni- oder bilateral nicht angelegten oberen lateralen Inzisiven zu identifizieren. Eine Nichtanlage wurde anhand radiologischer Befunde diagnostiziert.

Ergebnisse

Die Prävalenz der isolierten Nichtanlage der oberen lateralen Inzisiven lag bei 1,15%. Im untersuchten Kollektiv waren 66,3% Patienten weiblich, 33,7% männlich (p < 0,05). Eine bilaterale Nichtanlage bestand bei 47,8% der Patienten, eine unilaterale bei 52,2%, davon 48% auf der rechten und 52% auf der linken Seite. Der kontralaterale Schneidezahn war mikrodont in 43,75% der Fälle, davon rechts bei 47,6% und links bei 52,4%.

Schlussfolgerung

Die Ergebnisse dieser Studie erlauben den Schluss, dass die Prävalenz der isolierten Nichtanlage der oberen lateralen Inzisiven in einem syrischen Kollektiv innerhalb des durchschnittlichen Bereichs anderer Populationen liegt. Hinsichtlich der Ätiologie zeigte sich eine signifikante familiäre Komponente.
