Regenerative Endodontic Technique using a combination of Amoxicillin and Metronidazole. A review and report of two cases

The management of non vital anterior permanent teeth in children is a challenge for the clinicians. Once the tooth becomes non vital, the root development ceases, which renders the tooth weak and unable to withstand the physiological forces of mastication. This results in a high fracture rate, and therefore a poor prognosis in the medium to long term. Recently there has been a paradigm shift in the approach to this clinical problem through the use of regenerative endodontics. Despite many case reports, and a few case series that have been reported, the procedure is still shrouded in uncertainty as differing interventions have been used, though broadly based on similar principles. In the Department of Paediatric Dentistry at the Leeds Dental Institute we have used a particular regenerative endodontic technique (RET), using a mixture of two antibiotics (Amoxicillin and Metronidazole). In this paper, we aim to present the rationale for this technique and present two cases successfully treated and followed for up to two years.
