OBJECTIVE The aim of this study was to evaluate the capacity of potassium oxalate, fluoride gel and two kinds of propolis gel to reduce the hydraulic conductance of dentin, in vitro. MATERIAL AND METHODS The methodology used for the measurement of hydraulic conductance of dentin in the present study was based on a model proposed in literature. Thirty-six 1-mm-thick dentin discs, obtained from...

There are limited studies specifically on the prevalence of root dentine hypersensitivity or root sensitivity per se; most of the published information relates to the prevalence of dentine hypersensitivity (DH). Several investigators have suggested that there may be some justification on the basis of differing pathologies of distinguishing between those individuals complaining of DH who have re...

Forming a bond to dentin has been a great challenge. Dentin is a vital tissue composed of organic material and water in addition to the inorganic content. Operative procedures on dentin produce a loosely-bound surface of unorganized material known as the "smear layer". For optimum bonding to occur, this layer needs to be removed or altered. A dentin bonding agent should be biocompatible and sho...

Aims: to determine the prevalence of gingival recession and dentine hypersensitivity among the study population, and evaluate the distribution of dentine hypersensitivity among various types of teeth in mild, moderate and severe degrees of gingival recession. Relationship between the severity of gingival recession and dentine hypersensitivity was also evaluated. Materials and Methods: Clinical ...

Objectives. The aim of the present study was to review the published literature in order to identify relevant studies for inclusion and to determine whether there was any evidence on the clinical effectiveness of selected desensitizing toothpastes, calcium sodium phosphosilicate (CSPS), amorphous calcium phosphate (ACP), nanohydroxyapatite, and casein phosphopeptide-amorphous calcium phosphate ...

The relationship between clinical characteristics of carious dentin and bacterial colonization after partial caries removal is not completely understood. The aim of this study was to compare microbial counts between categories of carious dentin color, consistency and humidity, and to evaluate the correlation between these characteristics and the presence of cariogenic microorganisms in deep cav...

The purpose of this randomized, clinical, double-blind short-term trial was to evaluate the efficacy of a new lacquer containing a new component (phosphonic acid methacrylate) designed for treating dentine hypersensitivity. Eighty-eight patients participated in this study. At the first visit one tooth was treated with the lacquer (1), while another tooth was treated with a placebo (2). Sensitiv...

Marginal tissue recession is a common esthetic problem that is usually accompanied by dentin sensitivity, and patients frequently report a fear of dental loss. Lateral sliding flaps have been used for localized recession, but they are rarely used for multiple recessions. The aim of this paper was to report a case of coverage of multiple marginal tissue recessions by means of a lateral sliding f...
