Mandibular ü üncü molarlar n angulus k r olu umu üzerine etkisi

The purpose of this study was to estimate the relative risk of mandibular angle fractures among people with a lower third molar compared with those without a lower third molar. For this purpose, database research was performed on a whole PUBMED/MEDLINE by using key words “mandibular third molars” and “angle fractures”. The data obtained from 9 articles that had a similar statistical analysis; and that included mandibular angle fractures and other mandibular fractures as a control group were evaluated statistically. In these 9 retrospective cohort studies, the sum of cases was 6466 and the sum of mandibular angle fractures was 1769. The analysis of articles shows a relative risk for a mandibula to fracture, comparing patients with and without third molars, ranging from 1,2 to 3.6. The estimated relative risk across the 9 studies was 2.14 (95% CI 1.92–2.39). The results obtained in this study suggest that the presence of lower third molar may double risk of an angle fracture of the mandible.

ZET Bu makalenin amac , mandibular 3. molar di e sahip olan ve olmayan bireylerde mandibula angulus k r olu ma riskinin belirlenmesidir. Bu ama la, “mandibular third molars” ve “angle fractures” anahtar kelimeleri kullan larak PUBMED/MEDLINE veri taban nda literatür taramas ger ekle tirildi. Birbirine benzer istatiksel analiz yapm ve mandibula angulus k r klar ile beraber kontrol grubu olarak kabul edilebilecek ekilde di er mandibula k r klar n al malar na dahil etmi 9 adet makaleden elde edilen veriler istatiksel olarak de erlendirildi. Bu makalelerdeki retrospektif kohort al madaki vaka say s 6466 ve mandibula angulus k r say s 1769’idi. al malardaki r latif risk de erleri, 1,2 ile 3,6 aras nda hesapland . Ayr ca r latif risk ortalamas n n 2,14 oldu u belirlendi (%95 güven aral 1,92–2,39). Sonu olarak mandibular 3. molar di e sahip olan bireylerin olmayanlara g re ortalama 2 kat daha fazla mandibula angulus k r olu ma riskine sahip olduklar bulundu.
