Partial Caries Removal in Permanent Molars Restored Using Giomer

Официальное название

Clinical and Radiographic Evaluation of Partial Caries Removal in Permanent Molars Restored Using Giomer Compared to Resin Composite Restorations After 24 Months (A Randomized Clinical Trial)

Обзор

Dental manufacturers\' constant tweaks and improvements to composite compositions have resulted in a wider spectrum of restorative materials with positive long-term clinical performance. For example, the creation of bioactive giomer material with proven continuous multi-ion release has been beneficial in avoiding demineralization and imparting acid resistance to enamel and dentin.

Подробное описание

Giomer resin not only reduces the risk of secondary caries around restorations by releasing fluoride ions, but it also has good esthetic, physical, and handling features. Furthermore, advancements have been made to reduce giomer resin polymerization shrinkage by incorporating filler technology into the matrix system. As a result of these efforts, giomer resin is currently distinguished by its low shrinkage feature. According to the manufacturer, low shrinkage giomer resin has volumetric shrinkage of 0.8% and a polymerization shrinkage stress of 2.72 MPa. Several investigations were carried out to examine the overall clinical performance of low shrinkage giomer resin with equivalent success rates when compared to other restorative materials. The aim of the current study is to evaluate the effect of giomer in maintaining pulp health and dentin bridge formation after partial caries removal in permanent teeth with deep occlusal carious lesion when compared to resin composite restoration.

Вмешательства

• Процедура Beautifil II LS (Low-Shrinkage)
  The most remarkable feature of this light-cured universal composite for anterior and posterior restorations is its unique shrinkage of 0.85 percent by volume
• Процедура Nanohybrid resin composite
  Nanohybrid resin composites are the most popular, because they improve the distribution of fillers in the matrix by combining nanoparticles with submicron particles to achieve better mechanical, chemical, and optical properties
