The effectiveness of ultraviolet-C light-emitting diodes (UVC LEDs) is currently limited by the lack of suitable encapsulation materials, restricting their use in sterilization, communication, and in vivo cancer tumor inhibition. This study evaluates various silicone oils for UVC LED encapsulation. A material aging experiment was conducted on CF1040 (octamethylcyclotetrasiloxane), HF2020 (methyl hydro polysiloxanes), and MF2020-1000 (polydimethylsiloxane) under UVC radiation for 1000 h.

Large-scale engineering projects frequently involve pit excavation and wetland landfill operations, resulting in significant silt accumulation that occupies land and adversely affects the environment. Curing technology offers a solution for reusing this waste silt. In this study, straw ash and calcium carbide slag are proposed as effective curing agents for silt soil.

Objective: To clarify the role of concentrated growth factors (CGF) in the treatment of periodontal cement defects using calcium phosphate cement (CPC) with self-curing properties.
Methods: Thirty-six intrabony defects were randomly divided into two groups. The experimental group received CGF+CPC treatment (=18), while the control group received CPC treatment alone (=18).

Arteriovenous Malformations (AVM) can present themselves in an ample clinical spectrum. They worsen over time, creating local complications such as ulceration, destruction, infection, pain, and severe bleeding. Small focal AVMs can effectively be cured by surgery and/or endovascular techniques, whereas larger ones are of difficult management.

Objective: To evaluate the clinical efficacy of different surgical methods in congenital preauricular fistula surgery.
Methods: 60 patients with congenital preauricular fistula were selected and randomly divided into a microscope group of 30 cases and a macroscopic group of 30 cases. The microscope team used the fistula separation method to perform surgery along with the fistula opening.
