Prevention of tooth discoloration associated with triple antibiotics

Abstract

Regenerative endodontics has a potential to heal a partially necrotic pulp, which can be beneficial for the continued root development and strengthening of immature teeth. For this purpose, triple antibiotic mixture of ciprofloxacin, metronidazole, and minocycline was recommended as intracanal medicament in an attempt to disinfect the root canal system for revascularization of a tooth with a necrotic pulp. However, discoloration of the tooth was reported after applying this. This case shows the idea for preventing the tooth discoloration using a delivery syringe (SW-O-01, Shinwoo dental) to avoid the contact between the clinical crown and the antibiotics.

  Figure 1 Intraoral photographs. (a) Initial visit. Fracture of dens evaginatus was seen; (b) After triple antibiotics application; (c) 4 month follow-up after completion of the treatment. No discoloration was observed; (d) 1 year follow-up.

  Figure 2 Periapical radiographs. (a) Initial visit. Periapical radiolucency and dens evaginatus was seen on #35; (b) After MTA filling and resin core;. (c) 4 month follow-up. Apical radiolucency was decreased and also the apical root growing is observed; (d) 8 month follow-up. Apical dentin was thickened and continuous lamina dura is observed; (e) 1 year follow-up. Apical bone regeneration was completed and apical closure is observed. MTA, mineral trioxide aggregate.
