Abstract
The presence of unerupted teeth in close proximity to adjacent teeth can cause root resorption. The third molars and mandibular premolars are the most frequent teeth to be impacted and the relationship between impacted teeth causing root resorption of adjacent teeth has been well documented, but it is surprising how few studies have analysed the incidence of root resorption in these cases. This paper discusses two patients who have undergone molar root resorption due to adjacent unerupted impacted teeth.
