Article Synopsis
- - Two-dimensional materials like tin disulfide (SnS) are gaining interest due to their unique properties and effectiveness in various fabrication methods, particularly atomic layer deposition (ALD).
- - The study focuses on enhancing the quality of SnS thin films through post-annealing methods while examining the effects of different hydrogen sulfide concentrations (4.00% vs. 99.99%).
- - Results indicated that the best crystallinity, grain size, and electrical properties were achieved at a post-annealing temperature of 350 °C with 99.99% hydrogen sulfide, leading to a pure 2D-hexagonal SnS phase.
Objectives: To investigate the effect of epithelial growth factor (EGF) with collagen matrix (CM) on the gain of KT for buccally positioned implants in dogs.
Materials And Methods: In five dogs, four implants were placed buccally with the whole part of KT excision on the buccal side (two implants per each hemi-mandible). After one month, KT augmentation was performed: 1) free gingival grafts (FGG), 2) collagen matrix (CM) only, 3) CM soaked with 1 μg/g of EGF, and 4) CM soaked with 10 μg/g of EGF (n = 5 in each group).
A 28-year-old male patient was referred from an otorhinolaryngologist for managing unilateral chronic maxillary sinusitis (MS). The patient had undergone two functional endoscopic sinus surgeries (FESS), although the MS was not resolved. Based on his dental history, endodontic treatment had been done on the symptomatic area.
