ABSTRACT
Post and core systems have long been used in dentistry for the purposes of replacing missing coronal tooth structure, retaining the core, and providing sufficient retention and resistance form to the final restoration to re-establish original form and function. While Part 1 of this two-part article provided a history of post and core systems and materials and discussed empirical data regarding fiber-reinforced post systems, this second part of the article focuses on an alternative approach for developing a fiber-reinforced post and core system using a monoblock system via the injectable resin technique and a recently developed fiber-optic post. The present article explains the concept of a ferrule effect and demonstrates the novel restorative procedure.

Post systems have long been used in the roots of teeth to retain dental restorations. The primary objectives of current post and core systems are to replace missing coronal tooth structure, retain the core, and provide sufficient retention and resistance form to the final restoration to restore original form and function. Many varieties of user-friendly post and core systems are available today for different endodontic, restorative, and esthetic requirements. The present article provides a history of post and core usage in dentistry, describes various systems and materials for this purpose, and discusses empirical data regarding fiber-reinforced post systems.

Advancements in material research and adhesive technology have enabled the development of freehand bonding techniques that allow the preservation of remaining tooth structure and conservation of tooth structure during preparation-all while reinforcing the remaining tooth structure and improving the longevity and aesthetics of the restoration. In this article, the clinical concepts discussed were utilized with a recently developed composite resin material to restore the maxillary anterior dentition. Although the long-term benefits of this material remain to be determined, the utilization of this nanohybrid composite in this clinical presentation demonstrated an optimal functional and natural aesthetic result in the anterior region. Part 2 of this article will address the principles, techniques, and other considerations for achieving clinical success with direct posterior composite resin restorations.

Technological developments in photography have continued to facilitate and enhance the practice of dentistry. This evolution to a contemporary photographic process is revolutionizing the way clinicians diagnose, treat, and communicate with patients and colleagues. In this technologically progressing profession, clinicians should consider using an objective strategy for the selection and application of a reliable camera system that best suits the needs of their practice. This article provides clinicians with an overview of the function and basic components of a professional digital single lens reflex camera system, the criteria for evaluating and selecting a digital camera system, and the clinical applications for dental photography, as well as presents guidelines for obtaining a quality dental image.
