Objectives: This study aimed to compare the marginal adaptation of a cold ceramic (CC) sealer with the single-cone obturation technique with that of an AH-26 sealer with the lateral compaction technique in single-canal teeth.
Materials And Methods: In this in vitro experimental study, the root canals of 24 extracted single-rooted single-canal teeth were instrumented to F3 files by the crown-down technique and randomly assigned to 2 groups (n = 12). The root canals were obturated with a CC sealer and single-cone obturation technique with 4% gutta-percha in group 1 and with an AH-26 sealer and lateral compaction technique with 2% gutta-percha in group 2.

Materials and devices that harvest acoustic energy can enable autonomous powering of microdevices and wireless sensors. However, traditional acoustic energy harvesters rely on brittle piezoceramics, which have restricted their use in wearable electronic devices. To address these limitations, this study involves the fabrication of acoustic harvesters using electrospinning of the piezoelectric polymer PVDF-TrFE onto fabric-based electrodes.

- * A new fabrication technique has been developed to create flexible and stretchable piezoelectric fibers using a hybrid nanocomposite that can convert physical movements into electrical energy, offering high output voltage and power density.
- * Testing of the nanocomposite fibers shows they are non-toxic and compatible with human cells, making them promising candidates for smart biomedical devices and scaffolding in tissue engineering.
Background: To provide a continuous seal of the root canal, root-filling material should bond to the root canal dentin, ensuring the integrity of both the root-filling material and dentin remains in a static and functional state. The present study assessed the push-out bond strength of mineral trioxide aggregate (MTA) and cold ceramic (CC).
Materials And Methods: In this laboratory trial study, 20 single-rooted, extracted human teeth without caries and cracks were selected.
