Background: Early detection of peri-implant bone defects can improve long-term durability of dental implants. By the advances in cone-beam computed tomography (CBCT) scanners and introduction of new algorithms, it is important to find the most efficient protocol for detection of bone defects. This study aimed to assess the efficacy of metal artifact reduction (MAR) and advanced noise reduction (ANR) algorithms for detection of peri-implant bone defects.

The structural and antibacterial properties and viability of the samples were systematically investigated. The results of the Rietveld refinement indicated that both samples exhibited a single phase with cubic structure and space group Fm-3m.

Designed for immediate drug release from microneedles (MNs) and sustained release from microcapsules (MCs), this system utilizes lidocaine hydrochloride as the model drug. The fabrication process involved casting the hydrogel into MN molds, with MCs embedded in the backing layer, establishing a dual-release mechanism.

- This study explored how the size of BaTiO ceramics affects their piezoelectric properties using molecular dynamics simulations, confirming thermal and potential energy equilibrium at 300 K within 10 ns.
- As the ceramic size increased, both the mean square displacement and diffusion coefficients decreased, indicating a more uniform microstructure with reduced ion mobility due to fewer defects.
- The findings revealed that larger BaTiO samples showed enhanced polarization values, while the increased stress from better domain alignment limited the mobility of the domain walls, emphasizing the importance of size and microstructure in optimizing ferroelectric materials for electronic applications.
