Oral Microbiome and Response to Immunotherapy: Is It Time To Pay Attention?

Abstract Microbiome studies have shown associations between the presence of certain bacteria in the gut and response to checkpoint inhibition (CPI) therapies in cancer patients. Studies looking at any such potential associations between oral microbiome and response to CPI therapies are lacking. Oral cavity is an important microbial habitat. Microbes present in the oral cavity influence not only the local and systemic immune homeostasis; but also the gastrointestinal microbial diversity. If associations exist between specific gut microbes and response to CPI therapies, it is reasonable to assume that such relationships exist between oral microbes and therapy response in cancer patients. Since the findings from such studies will have resounding implications on patient selection for therapies and prophylactic or therapeutic modulation of microbes for prevention or treatment of malignancies; it is crucial that dental and oral research community pays attention and joins this research effort...

Platelet Concentrates and Their Clinical Applications in Oral and Maxillofacial Surgery, Periodontal, Dentoalveolar and Reconstructive Surgery and Endodontics. Current Review.

  Abstract During the last two decades a new technology appeared called platelet rich plasma preparations (PRP) [1], suggesting the main benefit in both hard and soft tissue wound healing for surgical use in regenerative medicine [2], as well as aiding in decreasing: rate of postoperative infections, pain and blood loss [3]. The PRP clinical applications include periodontal surgery, Oral and Maxillofacial surgery, aesthetic plastic surgery, spinal fusion, heart by-pass surgery, treatment of soft tissue ulcers, etc. [3]. However in the recent times there have been described different types of PRP concentrates and different clinical indications for every of them. The aim of this review is to enlist and describe the different types of PRP concentrates and their current clinical use in Dentistry and Oral and Maxillofacial surgery.

UV Irradiation as a Disinfection Method to Reduce Covid-19 Cross-Contamination in Dentistry: A Scoping Review

Abstract The new coronavirus (COVID-19) quickly became a pandemic. Its transmission occurs mainly by direct contact, but its indirect transmission cannot be neglected. The dental office becomes a place of a high risk of contamination, mainly through aerosols and particles decanted on the surface. Concern about biosafety has become imminent and essential supplies of personal protection have become scarce. Several methods of disinfecting protective materials, the environment, and surfaces are being studied to reduce cross-infection, such as ultraviolet (UV) light. Our objective was to conduct a review of the recent literature in order to elucidate the use of UV technology in disinfecting environments and surfaces to reduce crosscontamination of COVID-19 in the health area, and how it can be used in the dental area. The PubMed database was used, and the articles were selected according to their relevance between 2018 and 2020. It is concluded that decontamination in environments and surfa...

Prevalence and Pattern of Third Molar Impaction in Sample of Yemeni Adults

  Abstract Background and objectives:  Third molar impaction is an important clinical issue because impacted teeth predispose to periodontal disease such as pericoronitis, periodontitis, and other problems such as cystic lesions, neoplasm, root resorption and can cause detrimental effects on adjacent tooth resulting in pain, discomfort and loss of function. The pattern of third molar impaction in Yemeni population has not been described; thus, the aim of this retrospective radiographic study was to determine the prevalence and pattern of third molar impaction, angulation and level of eruption in sample of Yemeni adults. Materials and methods:  The study sample of 609 patients chosen randomly from patients who visited MASS x-ray centers in Sana’a and Ibb cities. The data collected included presence and impaction state, angulation, and depth of impaction of third molars. Results:  Out of total population, 236 (38.8%) showed at least one impacted third molar.

Mineral Trioxide Aggregate (MTA) vs Calcium Hydroxide in Direct Pulp Capping – Literature Review

Abstract Direct pulp-capping is a treatment for exposed vital pulp involving the placement of a dental material over the exposed area to facilitate both the formation of protective barrier and the maintenance of vital pulp. Direct pulp capping has been used as an alternative approach to the maintenance of vital pulp so that many tooth extractions and root canal treatments could have been avoided through the conservative approach of direct pulp capping. For this purpose different kinds of materials used such as Zinc Oxide Eugenol, Glass Ionomer (GI), Resin Modified Glass Ionomer (RMGI), Adhesive systems, Calcium Hydroxide, Mineral Trioxide Aggregate (MTA) and Bio dentine. The MTA clinically performed more effective than conventional Calcium Hydroxide liner as a direct pulp capping material, showed higher success rate than dycal. MTA easier to use clinically as a direct pulp capping material. MTA provided better long term results more effective than Calcium Hydroxide in maintaining long-...
