Background: Presence of impacted mandibular third molars in the oral cavity is most common. However, many times impacted mandibular third molars can lead to mandibular angle fracture. The purpose of this study was to know the incidence of mandibular fractures in patients with impacted mandibular third molars.
Materials and Methods: The articles for this systematic review and meta-analysis were procured from electronic databases like PubMed, Cochrane library, Embase, Medline etc. 19 articles were included in the qualitative analysis and 9 of those in meta-analysis. The risk of bias for observational studies was done with Newcastle-Ottawa Scale (NOS).
Result: All studies from 19 articles showed a significant association of impacted mandibular third molar in the incidence of mandibular angle fracture, the meta-analysis reported an overall odds ratio of 3.22 [95%CL = 1.56, 6.64].
Conclusion: This study concluded that there is a strong association between impacted mandibular third molar and incidence of mandibular fractures.
