초록
Regenerative endodontic treatment has the potential to heal a necrotic pulp, which can affect root developmentin immature teeth. However, several drawbacks and unfavorable outcomes are associated with regenerativeendodontic treatment, of which the most significant is coronal discoloration due to the presence of minocycline intriple antibiotic paste and mineral trioxide aggregate (MTA). To prevent tooth discoloration following pulp treatment, the modified triple antibiotics (ciprofloxacin,metronidazole, clindamycin) were used as canal disinfectants and Retro MTA, a ZrO2-containing calciumaluminate cement, was used to seal the canal. Following access cavity acquisition, the canal was copiouslyirrigated with 2.5% sodium hypochlorite. A modified triple antibiotic paste was then applied to the canal. Oncethe tooth was asymptomatic (after between 3 and 8 weeks), Retro MTA was carefully placed over the blood clotor a collagen plug. Follow-up radiographs revealed normal periodontal ligament space and root development. Intwo cases, successful regenerative endodontic treatment of the infected immature tooth, without discoloration,was achieved with disinfection using modified triple antibiotics and Retro MTA sealing.
Abstract
