Clinical studies have evaluated the effect of conventional periodontal surgical therapy. In general, although some clinical gain in tissue support may be attained, these therapies do not support regeneration of the periodontal attachment. Even though the biological possibility of periodontal regeneration has been demonstrated, the clinical application of this intrinsic potential appears difficult to harness; thus also conceptually most intriguing candidate protocols face clinical challenges. In this review, we explore the bioclinical principles, condiciones sine quibus non, that unleash the innate potential of the periodontium to achieve clinically meaningful periodontal regeneration (i.e. space-provision, wound stability and conditions for primary intention healing). Moreover, limiting factors and detrimental practices that may compromise clinical and biological outcomes are reviewed, as is tissue management in clinical settings.
Dentine hypersensitivity is a condition that is often present in individuals, leading them to seek dental treatment. It has been described as an acute, provoked pain that is not attributable to other dental problems. Its actual prevalence is unknown, but it is interpreted as very unpleasant by individuals. Several therapeutic alternatives are available to manage dentine hypersensitivity, involving both in-office treatment and home-use products. The aim of this literature review was to evaluate self-care products for managing dentine hypersensitivity. Among the products available, dentifrices and fluorides are the most studied self-care products, with positive effects. However, a high percentage of individuals is affected by the placebo effect. Among dentifrices, those containing potassium salts seem to be the most promising. Dental professionals need to understand the advantages and limitations of these therapies and use this knowledge in a positive approach that might help in decreasing dentine hypersensitivity among patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
