3D-guided endodontics is a cutting-edge, technology-driven method that provides a secure and dependable solution for addressing both partial and complete root canal calcifications, as well as root end surgeries. Advances in CBCT imaging and software now allow clinicians to easily evaluate root canal anatomy, project canal pathways, and estimate working lengths, facilitating accurate pre-treatment planning. This technology also allows for the creation of precise jaw models, eliminating the need for potentially distorted and inconvenient impressions. Additionally, this book will emphasize the vital role of STL files in 3D printing within endodontic procedures.

Dental bleaching, or teeth whitening, is a cosmetic procedure designed to lighten teeth and remove stains and discoloration caused by aging, consumption of staining substances, and certain medications. The process can be performed in-office by a dentist using high-concentration bleaching agents and special lights or lasers for quick results, or at home with custom-made trays and lower-concentration gels over several weeks. Over-the-counter products, such as whitening toothpastes and strips, offer more gradual results. The active ingredients, hydrogen peroxide and carbamide peroxide, break down stains within the enamel. While effective, bleaching can cause tooth sensitivity or gum irritation and may not be suitable for everyone, especially those with dental restorations or specific dental conditions. Results vary and maintenance treatments are often needed to sustain the whitening effect.

Recent advances in root canal obturation have significantly improved treatment outcomes through the development of bioceramic sealers, which offer superior biocompatibility, bioactivity, and antibacterial properties. and expand slightly upon setting to enhance sealing.
