Pressable ceramic restorations have been introduced and investigated, and found comparable to CAD/CAM ceramic in terms of mechanical properties; however, the effect of toothbrushing on the pressable ceramic has not been thoroughly investigated. The objective of the current study was to assess the effect of artificial toothbrushing simulation on the surface roughness, microhardness, and color stability of different ceramic materials. Three lithium disilicate-based ceramics (IPS Emax CAD [EC], IPS Emax Press [EP]; (Ivoclar Vivadent AG), and LiSi Press [LP] (GC Corp, Tokyo, Japan)) were examined.

- The study aimed to explore how thermocycling aging affects the surface roughness, color parameters, lightness change, color change, and microhardness of three lithium disilicate ceramics.
- Forty-five specimens of e.max CAD, e.max Press, and GC Initial LiSi Press ceramics were tested after undergoing 5000 thermal cycles, with measurements taken using specialized equipment for various properties.
- Results showed that while surface roughness increased for all materials post-thermocycling, e.max Press had the least color change, while GC Initial LiSi Press exhibited the highest microhardness.
Background: Diabetic emergencies are serious acute life-threatening complications of diabetes mellitus (DM). The Hajj season requires the health system in Saudi Arabia to prepare efficiently for the healthcare of millions of pilgrims, particularly for diabetic emergencies. Thus, diabetic emergencies need rapid recognition, diagnosis and treatment.
