Impacted tooth is one that has not fully or partially erupted and is “retained” in its eruption, remaining in the bone in the wrong position against another tooth, bone, or soft tissue, so that further eruption is unlikely. This condition is most common in third molars and is thought to be found in about 73% of young adults in Europe. Dentigerous cyst is the second most common odontogenic cyst and represents about 20-24% of all odontogenic cysts of the jaws. These cysts usually remain asymptomatic and rarely reach large sizes and displace the associated tooth. In our article we present four cases of impacted third molars with atypical localization and concomitant large dentigerous cysts. A brief review of the literature with similar findings is presented, as well as the different approaches to the treatment of these cases. For more information click here.
