Zinc Oxide-Eugenol paste retained in gingival mucosa after primary teeth pulpectomy

ABSTRACT

Aim

Long-term follow-up evaluations of pulpectomy in primary teeth have revealed retention of ZOE filling
particles in the periapical area even after root resorption. CASE REPORT: This paper reports a case of a child submitted to
pulpectomy with ZOE paste in primary teeth. After 28 months, the filling particles remained, having migrated to the alveolar
bone from the gingival vestibular mucosa during permanent dentition eruption. Aesthetics required periodontal surgical
removal of the paste particles. Primary teeth submitted to pulpectomy should be evaluated carefully both clinically and
radiographically to verify radicular and ZOE filling paste resorption. The consequences of retained particles during
permanent dentition eruption are unknown.
