Severe odontogenic infection: An emergency. Case report.

Odontogenic infections (OI) are a major reason for consultation in dental practice. They affect people of all ages, and most of them respond well to current medical and surgical treatments. However, some OI can spread to vital and deep structures, overcome the host immune system - especially in diabetic, immunocompromised or weakened patients - and even prove fatal.

Caries diagnosis using light fluorescence devices in comparison with traditional visual and tactile evaluation: a prospective study in 152 patients.

The objective of the study was to evaluate the in vivo effectiveness of two fluorescence techniques (DIAGNOdent and VistaProof) and of visual and tactile evaluation in the diagnosis of occlusal caries in permanent teeth. A total of 302 teeth (molars and premolars) from 152 patients were studied. The occlusal surfaces were cleaned using pumice mixed with water, followed by application of the diagnostic methods according to the instructions of the manufacturer, and of the visual and tactile methods according to the recommendations.

A versatile snap-on, metal-to-metal connection system for direct immediate loading with screw prostheses.

This technique introduces a system of abutments with a pressure or friction fitting to retain implant-supported prostheses. The system combines the chief advantages of cement and screw-retained prostheses, which are passively fit and easily removed from the mouth, respectively. This system provides an alternative to conventional immediate loading systems, since it allows easier adjustment and modeling of the prosthesis with a snap-on connection and easier removal from the implants.

A Classification Proposal for Peri-Implant Mucositis and Peri-Implantitis: A Critical Update.

Definitions of peri-implant mucositis and peri-implantitis vary in the literature, and no clear criteria have been established for the diagnosis and treatment of such disorders. This study proposes a classification for peri-implant mucositis and peri-implantitis based on the severity of the disease, using a combination of peri-implant clinical and radiological parameters to classify severity into several stages (Stage 0A and 0B = peri-implant mucositis, and Stage I to IV = periimplantitis). Following a review of the literature on the subject and justification of the proposed peri-implant disease classification, the latter aims to facilitate professional communication and data collection for research and community health studies.

Forensic dentistry in human identification: A review of the literature.

An update is provided of the literature on the role of odontology in human identification, based on a PubMed-Medline search of the last 5 years and using the terms: "forensic dentistry" (n = 464 articles), "forensic odontology" (n = 141 articles) and "forensic dentistry identification" (n = 169 articles). Apart from these initial 774 articles, others considered to be important and which were generated by a manual search and cited as references in review articles were also included. Forensic dentistry requires interdisciplinary knowledge, since the data obtained from the oral cavity can contribute to identify an individual or provide information needed in a legal process.

Dental management of patients receiving anticoagulant and/or antiplatelet treatment.

Introduction: Adequate hemostasis is crucial for the success of invasive dental treatment, since bleeding problems can give rise to complications associated with important morbidity-mortality. The dental treatment of patients who tend to an increased risk of bleeding due to the use of anticoagulant and/or antiplatelet drugs raises a challenge in the daily practice of dental professionals. Adequate knowledge of the mechanisms underlying hemostasis, and the optimized management of such patients, are therefore very important issues.

Oral toxicity produced by chemotherapy: A systematic review.

Introduction: Antineoplastic chemotherapy remains one of the most widely used management strategies in cancer, either alone or in combination with other types of treatment.
