Analysis of results obtained in Regenerative Endodontic procedures
Objectives: To evaluate the clinical and radiographic course of young permanent teeth diagnosed with pulp necrosis treated with regenerative endodontic procedures (REPs).
Methods: An experimental design, approved by the Ethics Committee of the FOUBA N° 009/2017. Inclusion criteria: Young permanent teeth diagnosed with pulp necrosis in systemically healthy children aged 6 to 14, who completed the treatment and attended the controls at the Department of Dentistry for Children between March 2017 and July 2021, who gave their assent and whose caregivers signed their informed consent for participation in the study. They were treated according to the REP protocol. 1st session: Anesthesia, total isolation, opening, rinsing with sodium hypochlorite 1.5% 20 ml and 17% EDTA 20 ml. Drying with sterile paper cones, placement of pure calcium hydroxide and propylene glycol paste, and Cavit-glass ionomer cement double coronal sealing. 2nd session: Anesthesia without a vasoconstrictor, total isolation, reopening, rinsing with 20 ml of EDTA, drying with sterile paper cones and passing a fine file through the apical foramen to form the clot. Sealing of the cervical third with added mineral trioxide. Intermediate coronary restoration with resin-modified glass ionomer cement (IVR). Clinical and radiographic follow up was performed at 3, 6, 12, 18, 24, 36 and 48 months, considering clinical failure the presence of pain or swelling in the area and radiographic failure the persistence of apical radiolucency.
Results: The sample comprised 17 teeth, 11 of which were incisors, 5 were premolars and 1 was a molar. Mean age was 9.88 ± 2.23 years. Clinical and radiographic treatment success was 64.70% at 3 and 6 months, and was found to increase to 100% at 12, 18 and 24 months follow up; no significant differences were observed between both types of teeth. Follow up performed at 3 years to 9 patients and at 4 years to 8 patients demonstrated that the success of the primary goal had been maintained.
Conclusions: Although the results of the treatments with the REP protocol are satisfactory in the established time, further studies with larger samples and long-term time points are required.
