Endod Dent Traumatol. 1993 Apr;9(2):81-4. doi: 10.1111/j.1600-9657.1993.tb00667.x.


The precise etiology of internal resorption is unknown but it is generally believed that triggering factors are infection and persistent chronic pulpitis. A case is presented with internal resorption, which developed subsequent to extrusion of iodoform paste from the adjacent tooth into the mandibular canal. According to clinical and radiographic examinations made after 7 years, the tooth was clinically asymptomatic, vital and the internal resorption was arrested without treatment.
