Pulp revascularization is a viable and effective treatment for immature necrotic teeth. The purpose of this case series was to report the outcomes of pulp revascularization using an alternative cervical sealing material (composed by calcium hydroxide, 2% chlorhexidine gel, and zinc oxide), which showed an acceptable clinical and radiographic performance in further indications, such as root canal filling and root resorptions. Case report: We selected seven traumatized immature permanent maxillary central incisors with crown fracture, extrusive luxation, and pulp necrosis. For pulp revascularization, we followed four main steps: passive decontamination, three-week interappointment dressing, scaffold, and cervical sealing. The cervical sealing was carried out with the association of calcium hydroxide, 2% chlorhexidine gel, and zinc oxide in a proportion of 2:1:2. The follow-up period was 24 months. We classified pulp revascularization outcomes as complete healing, incomplete healing, or failure. All cases showed complete healing.
