Regenerative Endodontic Treatment of Necrotic Primary Molars with Missing Premolars: A Case Series

The endodontic treatment of necrotic primary teeth with missing successors presents a unique clinical challenge. The purpose of this report was to describe the clinical and radiological outcomes of regenerative endodontic treatment (revascularization) of necrotic primary molars. Four infected necrotic primary second molars with missing premolars were treated with a two-visit revascularization protocol. The crowns were restored with amalgam or acid-etch composite resin. The teeth were followed-up clinically and radiographically for 18 months. At six months, all teeth demonstrated radiographic evidence of complete periradicular healing and positive response to cold test, and remained symptomless thereafter.
