In recent years, there has been a surge in the awareness regarding the phyto cannabinoid; cannabidiol. Between the time period from 1963 to 2000, only 460 publications can be found in a PubMed search while using cannabidiol as the keyword. The former pales in comparison to the record of 2769 publications found from 2008 to the present time. However, a limited amount of literature is available that discusses the therapeutic potential of cannabidiol, pertaining to the field of dentistry. In 1940, cannabidiol was isolated from cannabis for the first time, its structure being reported much later in 1963. Further research on Cannabis resulted in the declaration that “THC” is the active compound. Subsequent studies were then directed essentially based on the virtual exclusion of cannabidiol and other cannabinoids from cannabis. This was primarily due to the belief that the activity of cannabis was merely psychological activity. In retrospect, this seems unfortunate as many of the beneficial properties of cannabidiol which might have had a therapeutic benefit were overlooked. In the present review, attention will be focused on the therapeutic potential of Cannabidiol and the impact this may have on dentistry with the supplemental vision of encouraging further studies to reveal any other beneficial properties that may be present.

Posts have been suggested to strengthen weak endodontically treated teeth against intra-oral forces by transmitting torquing forces within the radicular dentin to supportive tissue along their roots. The case studies that follow show how an interdisciplinary approach was used to use complete veneer crowns after custom cast posts to repair severely damaged treated teeth and restore their appearance and functionality. Coordinated prosthetic and endodontic treatments with careful consideration of the patient's expectations and requirements were crucial for a positive result and patient satisfaction. For a very long period, a cast metal post and core were used to provide the foundation restoration for a prosthetic crown. The cast post and core system has the benefit that the core is a natural extension of the post. It is intended for the post to keep the core restoration, which rebuilds the destroyed coronal structure. In this article, cast post and core and porcelain fused to metal restorations for injured maxillary central incisors are discussed.
