The development of aesthetic dentistry recorded remarkable technological progress, especially with the increase in computer-aided design and manufacturing systems (cam cam). This precision -driven technology has led to the development of high -quality tooth restorations, which are often made from composite structures and ceramics. However, these materials are susceptible to discoloration over time and cause patients and practitioners to look for reliable whitening solutions. A recently published study published on January 29, 2025 gives significant insight into the effects of home bleaching with 15% carbamide peroxide on the surface properties of these materials.
The study aimed to evaluate how the brightening techniques of home affect the surface micro hortness and roughness of various CAD-CAM composite materials. A total of five different commercial CAD cam materials were examined, including polymer-infiltrated ceramic networks and resin composite materials. The researchers discovered a remarkable reduction in micro hardness of both polished and unpolished specimens after bleaching, especially with longer exposure times.
Lead researcher, including Alamoush et al. They observed significant decreases in all examined materials, with the polymer infiltrated ceramic network Vita Enamic showing the most considerable decline. Remarkably, the surface hardness was disadvantageous when the materials were unpolished.
One of the highlighted results of research is the relationship between the material type and its micro hardness reduction. The authors found that “home bleaching with 15% carbamide peroxide significantly reduced the micro hardness, which was mainly due to organic matrixerosion within the material.” This erosion was exacerbated under longer treatment time, which underlined the importance of a careful evaluation of the bleaching process before the application.
The results raise important questions for dentists and patients alike. Why do these materials show such different reactions to bleach? The study showed how different CAD cam structures are not only treated clearly, but also react differently due to their initial surface conditions. This discrepancy is crucial for practitioners if you advise the most suitable brightening methods after the course.
The study combines practical solutions with comprehensive analysis and contains clear guidelines for future dental practices on home wheating methods. By emphasizing polishing restorations in front of bleaching, tooth experts can help reduce some negative results associated with the treatment. The total results serve as a warning and an informative note for those who are considered in the guts of permits and are brought into harmony with the growing trend of patients who are looking for aesthetic improvements.
Further recommendations from the study indicate that adequate concentrations are contacted for bleaching in order to safely maintain the properties of CAD cam materials. Such research is indispensable, especially if the popularity of aesthetic dentistry and home treatments increases. This study not only illuminates the current dental practices, but also paves the way for future progress in restorative material applications and patient care.
Since the dentist industry is constantly adapting to consumer requirements and technological innovations, this research is an important memory of the nuanced interactions between treatment methods and material properties. It underlines the urgent need for thorough examinations in order to guide safe and effective dental practices in order to ensure patient satisfaction and maintain the integrity of advanced tooth restorations.
