Abstract

The success of endodontic treatment depends on proper shaping, disinfection, and obturation of the root canals. The filling material must adequately occupy the root canal space without extending the anatomical apex. Overfilling occurs when the filling material extrudes into the periapical tissues beyond the apex, which negatively affects the long-term prognosis. Endodontic overfilling cases can be addressed through surgical treatments aimed at preserving the tooth. This case report aims to inform to highlight endodontic surgery as an effective treatment for cases of failed root canal treatment due to overfilling of the obturation material. A 27-year-old male patient came to the Dental Conservation clinic at RSGM Prof. Soedomo with a chief complaint of the left maxillary lateral incisor, which had undergone discoloration and caused discomfort during chewing. The tooth had undergone root canal treatment two years prior. Periapical radiographic examination revealed that tooth 22 had been treated with overfilling obturation material and there was widening of the periodontal membrane in the periapical area. Root canal retreatment was performed using the crown-down preparation technique, followed by single-cone obturation with a bioceramic sealer. At the subsequent visit, an apicoectomy was performed, involving flap opening, alveolar bone exposure, removal of granulation tissue, and resection of 3 mm of the tooth apex. Retrograde filling with Mineral Trioxide Aggregate (MTA) was applied, followed by bone grafting and membrane placement. The area was sutured and covered with a periodontal dressing. The final restoration was completed using direct composite resin with intracanal retention. At the one-week follow-up, the patient reported no complaints. In conclusion, apicoectomy is an effective solution for overfilling cases. This case report demonstrates that surgery combined with retreatment can preserve the tooth and restore its function.

Abstract

Introduction: The success of veneers is influenced by the cementation procedure. Preheated composite resin has been proposed as a luting material for indirect adhesive restorations because of its improved mechanical and handling properties. Composite resin bonds effectively to tooth structures using adhesive systems. This study aimed to evaluate the effect of different adhesive application techniques and types of preheated composite resin as luting materials on the shear bond strength of lithium disilicate. Methods: Twenty-eight extracted maxillary premolars were prepared on the buccal surface to expose dentin and divided into four experimental groups. Lithium disilicate discs (3 mm in diameter and 1 mm in thickness) were cemented onto the prepared surfaces according to the assigned group protocols. Group IA received preheated microhybrid composite with total-etch adhesive, IB received self-etch adhesive; IIA received preheated nanohybrid composite with total-etch adhesive, and IIB received self-etch adhesive. After cementation, the samples were immersed in artificial saliva at 37oC for 24 hours. Shear bond strength testing was conducted using a universal testing machine. Debonded samples were observed under a stereomicroscope to determine bonding failure. Data were analyzed using two-way ANOVA and post hoc LSD tests with a 95% confidence level. Results: Total-etch adhesive demonstrated higher shear bond strength (SBS) than self-etch adhesive for both composite types. The highest SBS was observed in the total-etch microhybrid group (14.03 ± 0.12 MPa), followed by the total-etch nanohybrid group (12.99 ± 0.09 MPa) and the self-etch microhybrid group (13.67 ± 0.18 MPa), while the lowest value was recorded in the self-etch nanohybrid group (10.21 ± 0.22 MPa) Conclusion: Preheated microhybrid composite resin produced higher shear bond strength with lithium disilicate than preheated nanohybrid composite resin, and the total-etch adhesive technique resulted in higher shear bond strength than the self-etch technique.
