Effects of Ph and Temperature on Dental Materials in Saliva and Oral Fluids

Abstract

The oral environment exposes dental materials to a range of pH and temperature, therefore influencing their durability and functionality. This research investigates how pH and temperature influence the dental materials in oral fluids and saliva.

Objective: To determine the impact of temperature and pH fluctuation on physical and chemical characteristics of dental materials.

Methodology: 60 dental materials specimens including composites, ceramics, and metals was employed in this in-vitro experimental study that was performed in a dental materials lab. SEM, EDX, and nanoindentation were used to examine the surface morphology, chemical composition and mechanical characteristics of the materials. The specimens were placed and pH levels (acidic, neutral, and alkaline) and temperatures included room temperature, body temperature and elevated temperature were applied.

Result: Exposure to high temperatures (p 0. 001) and acidic pH (p 0. 05) significantly modified the material's properties. Under acidic conditions, the surface roughness increased by 35. 2% 5. 1% while the mechanical strength dropped by 22. 5% 3. 2% at high temperatures.

Conclusion: The findings highlight the need of taking pH and temperature fluctuations in the oral environment into account while choosing and producing dental materials. Knowing this helps one to improve the durability and efficacy of dental restorations.
