Abstract

Introduction: Traumatized immature permanent teeth can cause pulp necrosis, leading to imperfect root formation, and thus resulting an open apex. The apical opening of the immature teeth is mostly large and thus may lead to difficulties in performing a root filling. In such cases, apexification is mandatory before doing root canal treatment. The aim of this case report was to inform that apexification and direct veneer was suitable to treat Ellis class IV fracture with necrotic pulpCase Report: 21-year-old female came to the Dental Conservation Clinic RSGM Prof. Soedomo Faculty of Dentistry UGM with chief complaint of right central incisive maxilla fracture and tooth discoloration. Radiographic examination showed an open apex of tooth 11 with a diffuse apical radiolucent area. Root canal treatment and apexification were carried out using circumferential technique and Mineral Trioxide Aggregate (MTA). Vertical warm obturation was performed, followed by intra coronal bleaching in the next visit. Final restoration was carried out using direct composite veneer. Post treatment radiographic showed a 1 mm diameter of radiolucent area at the apex in a good healing process.Conclusion: Apexification using MTA can be used to treat an open apex tooth. 1Student of Specialist Programme in Conservative Dentistry, Dentistry Faculty, Gadjah Mada University 2Department of Conservative Dentistry, Dentistry Faculty, Gadjah Mada University

Abstract

Background: One crucial function of root canal irrigation is eliminating smear layer, thus increasing apical sealing ability of endodontic sealers. This study was conducted to compare the effect of final irrigation using 17% EDTA, novel silver citrate, and 0.2% chitosan nanoparticles agitated manually, sonically, and ultrasonically on apical sealing ability of bioceramic sealers in the apical third.Method: Forty-five mandibular premolars were prepared and randomly divided into three experimental groups (n=15). Group 1 used 17% EDTA as the final irrigation, group 2 used novel silver citrate, and group 3 used 0.2% nanoparticle chitosan. Each group was divided into three subgroups (n=5), with subgroup A was using manual agitation, subgroup B using sonic, and subgroup C using ultrasonic. All teeth were obturated using single cone and bioceramic sealers. Observations were made using 120x magnification SEM. The sealer's apical sealing ability was measured by comparing cross-sectional area of obturation area with cross-sectional area of preparation area in the apical third.Result: Results of two-way ANOVA showed that there was a significant difference in final irrigation material (p<0.05), but there was no significant difference in technique and interaction of final irrigation material and technique (p>0.05).Conclusion: Irrigation materials affected the apical sealing ability of bioceramic sealers in the apical third, and 0.2% chitosan nanoparticles produced the highest apical sealing ability than other groups. There is no difference in effect of final irrigation technique and the interaction of materials and final irrigation technique on apical sealing ability of bioceramic sealers in the apical third.
