Analysis of Microhardness and Surface Roughness in Newer Pedo Shade Nanocomposite: An In Vitro Study

Type: article
Abstract: The materials most frequently utilized in clinical dentistry are restorative resins, which have revolutionized the field of esthetic and conservative dentistry due to their excellent mechanical and optical properties. 1 Among these, bonded resin composites are considered the most esthetically pleasing and functionally effective restorative materials, especially in pediatric dentistry for the treatment of severely decayed primary incisors.[2][3][4] Unlike conventional restorative materials such as amalgam, resin composites offer superior esthetics by mimicking the natural translucency and shade of teeth.However, despite their advantages, these materials are vulnerable to wear, degradation, and discoloration over time due to continuous exposure to various oral conditions, including mechanical forces, temperature changes, and chemical interactions with food and beverages.5 This progressive deterioration often leads to restoration failure, necessitating further research and development to improve the longevity and durability of these materials.It is well established that dietary factors and the oral environment significantly influence the physical properties of composite materials, particularly their hardness and surface roughness.6 A newer Pedo shade nanocomposite has been developed specifically for pediatric dentistry, particularly for use in strip crowns in severely decayed primary anterior teeth.This composite is designed to closely match the natural shade of primary teeth, enhancing esthetic outcomes while providing sufficient strength and durability.However, before this material can be widely adopted in clinical practice, its mechanical properties must be thoroughly evaluated.
