• The purpose of this research was to study the pathological signs observed in temporary molars that had undergone pulpotomy.

  Materials and methods. 79 intraoral radiographs of molars that had undergone pulpotomy were evaluated. Internal and external resorption patterns and the presence of radiolucent lesions in the furcation were studied.

  Results. Pathological internal radicular reabsorption was observed in 43% of temporarymolars and pathological external radicularresorptionwas observed in 34.2% of the sample. The radiolucent lesions of the radicular furcation were present in 39.1% of temporary molars.

  Conclusions. Themost commonradiographic manifestationwas pathological internalroot resorption. However, this radiographic failuremay be considered only a secondary effect if it is not accompanied by clinical manifestations and does not compromise tooth function before physiological exfoliation.
