Case series on two-stage disinfection in regenerative endodontics on permanent mandibular molar with blunderbuss canal

Abstract

Background: Revascularization is a promising approach as it promotes root end closure forming healthy, thick root dentin at the apex which provides clinical and radiographic success due to the elimination of bacteria and disinfection of the canal which gives a 100% sterile environment to receive SCAP. Aim: To examine the effect of a regenerative endodontic procedure on immature necrotic teeth with apical periodontitis Method: An 8-year-old medically fit boy was referred to the department with a lingering type of pain in the immature permanent mandibular first right molar. Bleeding was induced in the root canals at the third appointment. The blood clots (scaffolds) were covered with MTA, and the tooth was restored with a composite filling. Recall sessions were scheduled after one month and 3 months, when the tooth appeared asymptomatic clinically and radiographically, with considerable periapical healing. Conclusion: An immature multirooted tooth with necrotic pulps and periapical radiolucency was managed with evident clinical and radiographic success, wherein non-setting calcium hydroxide paste and triple antibiotic paste were used sequentially to guarantee complete canal disinfection.
