Abstract

There have been infrequent case reports of bilateral root resorption in the lower second molar secondary from impacted third molar removal with bone regeneration without pain. Root resorption is commonly observed during third molar surgical impaction that affects mandibular second molars. The bone regeneration into the adjacent affected tooth is evident simply after the surgical extraction of the impacted tooth. However, there have been a few previous reports on the prognosis of the remaining resorbed tooth. Most dentists often choose to extract them when damaged if root resorption is observed. This report case involved bilateral root resorption of the lower second molar due to lower adjacent impacted third molar teeth and bone regeneration without pain sensation. After surgical extraction of bilateral lower impacted third molar teeth, the remaining teeth retained vital pulp and survived as functional teeth.
