ABSTRACT Dentine hypersensitivity (DHS) remains a worldwide under-reported and under-managed problem, despite making some dental treatments more stressful than necessary and having a negative impact on the patient's quality of life. This article is designed to build dental professionals' confidence and remove any confusion regarding the diagnosis, prevention and treatment of sensitive teeth caused by dentine hypersensitivity in those patients known to be at risk. There is a need for simple guidelines, which can be readily applied in general practice. However, it is also obvious that one strategy cannot suit all patients. This review describes a DHS management scheme for dental professionals that is linked to management strategies targeted at three different groups of patient. These patient groups are: 1) patients with gingival recession; 2) treatment patients with toothwear lesions; and 3) patients with periodontal disease and those receiving periodontal treatment. The authors also acknowledge the role of industry as well as dental professionals in a continuing role in educating the public on the topic of sensitive teeth. It is therefore important that educational activities and materials for both dental professionals and consumers use common terminology in order to reduce the possibility for confusion.
This review article provides practical, evidence-based guidance on the management of dentine hypersensitivity for dental professionals covering diagnosis, prevention and treatment. Sensitivity associated with gingival recession, toothwear and periodontal disease and periodontal treatment are specifically addressed in the article.

    ABSTRACT: The aim of the study was to determine the in vitro effects of toothpaste desensitizing agents on the hydraulic conductance of dentin. The study included a total of 60 third healthy human molars, recently extracted without occlusal contact, of patients between 15-30 years, which were cleaned, disinfected (thymol 0.1% for 24 h) and stored at room temperature for a maximum of 14 days. The crowns were sectioned perpendicular to the tooth axis under abundant refrigeration, obtaining a disc of 1 mm ± 0.1 mm thickness for each crown. Disks were separated into the following 3 groups of treatment, of 20 discs each, which were brushings (brush electrical Oral-B® Pro Health Power) for 2 min only by their occlusal face with: A) Colgate® Sensitive Pro Relief with Pro Arginine technology (Colgate-Palmolive, USA); B) Sensodyne® Quick-Relief (GlaxoSmithKline, UK), and C) distilled water as a negative control. The data were statistically analyzed by Kruskal-Wallis and Mann-Whitney tests. The results, expressed as means in μl/cm−2/min−1/cmH2O−1, separated by group were: A) 0.00650 (± 0.00384); B) 0.00800 (± 0.00472), and C) 0.03649 (± 0.03042). It can be concluded from the study that 2 dentin desensitizing agents show a significant decrease in hydraulic conductance in dentin. Statistically significant differences were found between the control group and Sensodyne® Quick Relief (P = .000) and between the control group and Colgate® Sensitive Pro Relief (P = .000). There was no difference between the 2 toothpastes (P = .317).

    ABSTRACT: The aim was to evaluate the influence of time of application of diamine silver fluoride on the hydraulic conductance.Method:The sample of this prospective experimental study included 60 healthy human third molars with indications of extraction in malocclusion. These were extracted from patients between 18 and 30 years of age. 4 groups of 15 dentin disks were obtained:GC(No treatment),G1(were actively treated with diamine silver fluoride for 15 seconds),G2(30 seconds),G3(60 seconds).Then, was measured hydraulic conductance of dentin. The rate of flow of the fluid through the dentin disks was measured by recording the initial position of a bubble of air inside a capillary in 20 minutes.With the Wilcoxon signed rank test, it was established that there is a statistically significant difference in hydraulic conductance between the control group and the samples treated with desensitizing solution based on diamine silver fluoride/potassium iodide. There was no statistically significant difference between the groups treated with different application times of the desensitizing solution. There was no difference in hydraulic conductance between disks with different application times of desensitizing solutions of diamine silver fluoride/potassium iodide.
