Aim: The purpose of the study is to evaluate and compare the biological and chemical-physical properties of four different root-end filling materials.

Materials And Methods: Cytotoxicity towards murine odontoblasts cells (MDPC-23) was evaluated using the Transwell insert methodology by Alamar blue test. Streptococcus salivarius, S. sanguis, and S. mutans strains were selected to evaluate the antimicrobial activity by agar disc diffusion test. Solubility was determined after 24 h and 2 months. pH values were measured after 3 and 24 h. To evaluate radiopacity, all materials were scanned on a GE Healthcare Lunar Prodigy.

Results: Excellent percentage of vitality were obtained by mineral trioxide aggregate (MTA)-based materials and Biodentine. MTA-Angelus, ProRoot MTA, and Intermediate Restorative Material (IRM) showed the highest values for the inhibition zones when tested for S. mutans, while Biodentine showed the largest inhibition zone when tested for S. sanguis. All the materials fulfilled the requirements of the International Standard 6876, demonstrating low solubility with a weight loss of less than 3%. No significant reduction in pH value was demonstrated after 24 h. ProRoot MTA and MTA-Angelus showed the highest values of radiographic density.

Conclusions: The differences showed by the root-end filling materials tested do not cover completely the ideal clinical requests.

Aim: This report highlights successful management of a rare case of a mandibular premolar with Oehler's Type IIIb Dens Invaginatus (DI) and peri-invagination periodontitis with guided intentional replantation (IR) without root canal treatment.

Methods: A 22-year-old female patient reported with discomfort and a sinus tract associated with tooth #21. Clinical examination and cone beam computed tomography revealed tooth #21 had an Oehler's Type IIIb DI with peri-invagination periodontitis.

Root-filling materials for endodontic surgery: biological and clinical aspects.

The placement of root filling materials aims to prevent the occurrence of post-treatment apical periodontitis following completion of endodontic treatment. Materials should possess properties that will not permit bacterial invasion and infection, namely excellent sealing ability and/or antibacterial properties. In root-end filling procedures or repair of root perforations, the root filling materials are placed in a particularly challenging clinical environment, as they interface with a relatively large area with the periradicular tissues.

Aim The objective of this study is to evaluate the efficacy of Guttaflow Bioseal (Coltene/Whaledent, Altstätten, Switzerland) in achieving an apical seal when utilized as a retrograde filling material in comparison to mineral trioxide aggregate (MTA). Methods Twenty single-rooted single-canaled human teeth were randomly allocated into two equal groups according to the used retrograde filling materials: Guttaflow Bioseal in group I and MTA in group II. The crowns were sectioned, and the root canals were prepared with rotary files and obturated (single cone technique with a resin-based sealer).

The absence of a barrier in an open root apex makes endodontic treatment challenging as root-filling material can easily reach the surrounding tissue. The aim of the study was to compare the apical microleakage associated with mineral trioxide aggregate (MTA), biodentine, custom-made gutta-percha with MTA plus and custom-made gutta-percha with Adseal in immature permanent teeth by dye penetration method. Apical 2 mm of 60 single-rooted mandibular premolar teeth was resected to create divergent open apices and 10 teeth each were filled with Biodentine plug, MTA plug, custom-made gutta-percha with MTA plus sealer and custom-made gutta-percha with Adseal sealer.

Article Synopsis
  • The study assesses how combining various bioactive root-end filling materials with a composite bone graft influences healing in periapical tissues following endodontic microsurgery, using a triple-blinded clinical trial design.
  • 56 patients, aged 20 to 50 with specific dental issues, were randomly divided into two main groups based on root-end filling materials (MTA vs. TotalFill) and further split into subgroups with or without bone grafts.
  • After 12 months, the results showed no significant differences in healing or success rates across the groups, with no adverse effects reported.
