Benefits of Microwave-Assisted Heat Treatment for Sintered Diopside Glass-Ceramics.

Sinter-crystallization is a specific method of producing glass-ceramics that allows the manufacture of complexly shaped products, composites and solder. However, it usually is limited when the glass powders used are characterized by a high crystallization trend. This study proposes a new opportunity to improve the sinter-crystallization and demonstrates the benefits of microwave processing using diopside (CaMg(SiO)) glass-ceramics with an enhanced crystallinity of ~70%.

Laser-assisted Root Canal Filling Removal of Lower Incisors - A Micro-CT Study.

Aim: To compare the efficiency of root canal filling removal from oval-shaped root canals with high-energy Er:YAG laser and additional instrumentation with a rotary Ni-Ti XP-Endo Finisher R system.

Materials And Methods: The study was accomplished on 12 freshly extracted single-rooted mandibular incisors with one straight oval-shaped root canal, shaped with XP-Endo Shaper 30/.04 and obturated by using the warm vertical condensation technique subjected to further endodontic orthograde retreatment.

Micro-CT Study on the Supplementary Effect of XP-Endo Finisher R after Endodontic Retreatment with Mtwo-R.

Background: During the course of a non-surgical orthograde endodontic retreatment, supplementary instrumentation is usually required for better removal of root canal filling material.

Aim: The aim of this study was to assess the effectiveness of XP-Endo Finisher R in endodontic retreatment of oval root canals.

Materials And Methods: The study was performed on extracted mandibular incisors preliminary cut at the cementoenamel junction.
