Triple antibiotic paste in the treatment of a necrotic primary molar

Abstract

This paper reports a case of an eight-year-old male who presented with a primary molar which had previously undergone a pulpotomy. Subsequently pulpal necrosis, internal resorption and mobility of the tooth occurred, complicating the case. A repeat pulpotomy was performed together with the use of triple-antibiotic paste (TAP). At the 10-month follow-up no clinical signs of disease were found. Complete healing of the furcal radiolucency was demonstrated, with bony infill, no mobility and resolution of the previous widening of the periodontal ligament. It appears that TAP may be a viable treatment modality to enable retention of necrotic primary teeth with a poor prognosis.
