# Innovation in Dental and Orthodontic Materials
###### Abstract  
The evolution of dental and orthodontic materials has been significantly influenced by technological advancements, reshaping patient care in offering more efficient, effective, and patient-friendly treatments. Innovations such as nanomaterials and advanced imaging techniques are enhancing the treatment outcomes and streamlining clinical procedures. These developments are transforming various fields, including restorative dentistry, orthodontics, and endodontics. Nanotechnology has garnered considerable attention in endodontics due to its potential to improve the precision and overall outcomes of treatment. Nanomaterials like cerium oxide nanoparticles (CeO2) have been shown to enhance biocompatibility and possess reactive oxygen species (ROS)-scavenging properties, which are crucial for preventing inflammation and bacterial invasion in titanium implant coatings. These nanoparticles significantly reduce oxidative stress and improve the long-term performance of dental implants and restorative materials. Moreover, they have been integrated into root canal sealants and irrigation solutions, contributing to better cleaning, sealing, and disinfection outcomes [1]. Orthodontic treatments have also greatly benefited from advanced imaging technologies, especially Cone Beam Computed Tomography (CBCT). This technology plays a pivotal role in accurately assessing the root resorption during orthodontic traction, which is a common concern when treating impacted maxillary canines. Research has demonstrated that using light, controlled orthodontic forces, monitored via CBCT imaging, helps prevent excessive root resorption in both impacted and erupted canines. This technique allows orthodontists to tailor their treatment plans more effectively, minimizing risks to the structural integrity of the teeth while achieving the optimal alignment [2]. Innovative orthodontic devices have progressed the treatment of gummy smiles. For instance, the combined use of Bite-Jumping Appliances (SBJAs) and high-pull J-hook headgear has been shown effective in managing vertical growth in the maxillary arch, reducing the appearance of a gummy smile in Class II patients. These devices promote mandibular growth while inhibiting the vertical growth of the maxillary anterior teeth, offering a non-invasive method for improving facial aesthetics during the growth period. Such advancements highlight how orthodontic treatments can significantly enhance both functional and aesthetic outcomes, contributing to increased patient satisfaction [3]. In restorative dentistry, silane treatment has been explored for improving the bond strength between resin-based composite (RBC) post-and-core materials and CAD/CAM blocks. Alongside recent studies suggesting that silane treatment does not substantially improve the immediate microtensile bond strength (uTBS), concerns have also arisen regarding its effect on the bond strength over time. In certain adhesive systems, silane treatment was found to reduce the uTBS values over time, underlining the challenges inachieving long-term durability in composite restorations. These findings stress the need for further research to optimize surface treatments and the adhesive protocols for enhanced long-term performance [4]. Nanoparticles also show great promise in the management of root canal infections. By improving the cleaning efficiency of root canal systems, nanoparticles contribute to better sealing, preventing reinfection and promoting faster healing. When integrated into endodontic irrigants and sealers, these materials enhance antibacterial activity and biocompatibility, leading to an improved overall performance in root canal treatments. Their small size and high surface area enable them to interact at the molecular level, which is vital for overcoming the challenges related to root canal disinfection [5]. Furthermore, addressing the oral health needs of patients with neurodegenerative diseases such as Alzheimer's and Parkinson's has become increasingly important.
