Despite obstacles and the risk of adverse events, CAR T cell therapy could be used for patients with treatment-resistant cancer. Clinical trials are underway to determine the efficacy of this approach for the treatment of melanoma.

To treat patients with this condition using endosseous implants to support a functional prosthesis, grafting procedures have been advocated. The multiple surgical steps involved in the reconstruction of the resorbed maxilla, however, can be a significant barrier to patient acceptance of grafting treatment protocols. The success of graftless concepts using tilted and zygomatic implants has led to a higher case acceptance as the treatment can be accomplished in one appointment. Over the past two decades, the experience clinicians have gained using zygomatic implants has resulted in a redesign of the implant aimed at addressing the challenges associated with the treatment of patients with moderate to advanced resorbed maxillae to better serve these patients.This article will provide an overview of the initial responses by dental education institutions to the impacts of COVID-19 and their modifications of operations implemented to reopen all phases of their educational programs in this "new normal" environment. It will also discuss potential long-term impacts on dental education based on the experiences of four dental schools.Implants used to replace molar teeth present issues of space distribution and crown contours that are unique to these sites. Because the diameter of the implant typically is smaller than that of the tooth being replaced, and the circular shape of the implant does not replicate the anatomy of the tooth, a large gingival embrasure area between the implant platform and adjacent tooth often results. Upon the review of radiographs of molar implants placed over an 11-year period in one private practice, the authors identified an unusually high incidence of approximal, cervical, and root caries on teeth adjacent to these implants. This retrospective radiographic study investigated the incidence of decay as related to (1) the horizontal distance from the implant to the adjacent tooth (ie, the implant-tooth distance, or ITD) as measured at the alveolar crest, (2) the vertical distance from the apical portion of the prosthetic contact area to the implant platform, and (3) the presence of an existing restoration on the adjacent tooth. Of the three variables examined, both the horizontal distance of the implant to a natural tooth (ITD) and the presence of an existing restoration on an adjacent tooth proved to be significantly correlated with the incidence of decay. Results showed that incidence of decay ranges from 7.4% when the ITD is less than 2 mm to 40% when the ITD is ≥6 mm. The mean ITD in cases in which decay was found was 4.1 mm, and it was 3.5 mm in cases that showed no decay (P = .005). It is therefore suggested that the horizontal threshold of 4 mm be considered as the "critical ITD." The results also indicated that the presence of a previous restoration on an adjacent tooth increases the incidence of decay to a statistically significant degree with an odds ratio of 2.25 at a 95% confidence level. This information may prove useful in diagnosis and treatment planning for molar implant replacement.Esthetic dilemmas often require an interdisciplinary approach to achieve an optimal result. This article describes such a case in which the patient presented with unesthetic porcelain crowns on structurally compromised maxillary anterior teeth. The maxillary incisors had failing root canals, advanced mobility, and deep periodontal pockets. In addition, there was a congenitally missing maxillary lateral incisor. The canine substitution created a severely canted appearance exacerbated by the patient's high smile line. A coordinated interdisciplinary treatment plan was put into action to satisfy the patient's chief complaints and achieve a successful outcome. In this instance, this approach involved a periodontist, orthodontist, and prosthodontist, as well as initial input from an endodontist.Electronic cigarette usage has become increasingly prevalent among all age groups, particularly over the past 10 years. While many of the effects of electronic cigarettes are still under investigation, systemic and oral impacts have begun to be elucidated. This article will discuss known systemic complications of electronic cigarette usage, known oral effects including pathological, microbiological, and anatomic factors, and considerations around smoking cessation efforts for electronic cigarette users. In reviewing these topics, this article will provide the dentist with considerations for evaluation and treatment of electronic cigarette users.During and after commonly performed dental surgical procedures, hemorrhaging that is greater than normal can occur in patients who do not have bleeding disorders. This article discusses the management of various potential hemorrhagic scenarios with respect to extractions and periodontal and implant surgeries. learn more Protocols for controlling bleeding are delineated for primary and postoperative hemorrhaging. Background information is provided with respect to blood vessels, hemostatic mechanisms, patient evaluations, and drugs that may need to be suspended prior to dental surgical procedures.Artificial Intelligence (AI) builds upon the digital tools the dental profession has already adopted. It promises to transform the patient journey outlined above and support the quest of the dental community to improve oral health. In this review, we will detail how AI is used today in the clinic to improve patient care and experience. The review will start with the diagnostic capabilities of AI and then move to how it can be used to support treatment planning and patient communication. It will end with a discussion of how AI quantification helps dentists monitor longitudinal outcomes for patients and across the practice.
