Diabetes and periodontal diseases: what does the consensus report of the Joint EFP/AAP Workshop on Periodontitis and Systemic Diseases say?
This is the summary of the report issued by the Joint European Federation of Periodontology and the American Academy of Periodontology Workshop on Periodontitis and Systemic Diseases: Diabetes and periodontal diseases: consensus report of the Joint EFP/AAP Workshop on Periodontitis and Systemic Diseases (April 2013) Context Diabetes and periodontitis are complex chronic diseases with an established bidirectional relationship. There is long-established evidence that hyperglycemia in diabetes is associated with adverse periodontal outcomes. However, given the ubiquity of periodontal diseases and the emerging global diabetes epidemic, the complications of which contribute to significant morbidity and premature mortality, it is timely to review ...Read More »

This summary is based on the Critical Appraisal published in the Journal of Esthetic and Restorative Dentistry: Approaches to caries removal: what the clinical evidence says (April 2013) Context It is very common that complete caries removal in vital, asymptomatic teeth with deep carious lesions ends in unavoidable exposure of the pulp. As a result, the complexity and cost of treatment increases dramatically and many patients are left with extraction as their only viable option.The review appraises evidence which supports alternative treatments designed to preserve the vitality of the tooth and thus avoid extraction. Studies Reviewed Evaluation of Atraumatic Restorative Treatment and Sealants under ...Read More »
