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. Keywords: Mandibular angle fractures, mandibular third molars, relative risk. ÖZET Bu makalenin amacı, mandibular 3. molar dişe sahip olan ve olmayan bireylerde mandibula angulus kırığı oluşma riskinin belirlenmesidir. Bu amaçla, “mandibular third molars” ve “angle fractures” anahtar kelimeleri kullanılarak PUBMED/MEDLINE veri tabanında literatür taraması gerçekleştirildi. Birbirine benzer istatiksel analiz yapmış ve mandibula angulus kırıkları ile beraber kontrol grubu olarak kabul edilebilecek şekilde diğer mandibula kırıklarını çalışmalarına dâhil etmiş 9 adet makaleden elde edilen veriler istatiksel olarak değerlendirildi. Bu makalelerdeki retrospektif kohort çalışmadaki vaka sayısı 6466 ve mandibula angulus kırığı sayısı 1769’idi. Çalışmalardaki rölatif risk değerleri, 1,2 ile 3,6 arasında hesaplandı. Ayrıca rölatif risk ortalamasının 2,14 olduğu belirlendi  (%95 güven aralığı 1,92–2,39). Sonuç olarak mandibular 3. molar dişe sahip olan bireylerin olmayanlara göre ortalama 2 kat daha fazla mandibula angulus kırığı oluşma riskine sahip oldukları bulundu.
