fa A practice-based randomised controlled trial of the efficacy of three interventions to reduce dentinal hypersensitivity ترمیمی Cosmetic and Restorative Dentistry پژوهشي Research <p> <strong>Objectives </strong></p><p> The aim of this study was to evaluate the efficacy of three different interventions (non-desensitising toothpaste, desensitising toothpaste and professionally applied dentine bonding agent) in reducing dentinal hypersensitivity over a 2-week, 3-month and 6-month-period in a dental practice setting. </p><p> <strong>Methods</strong></p><p>  This was a randomised controlled, single-blind parallel-group trial conducted in general dental practice by a single general dental practitioner. Seventy-five subjects were randomly allocated to three groups non-desensitising toothpaste (NDT), desensitising toothpaste (DT) and professionally applied desensitising agent (DA). Dentinal hypersensitivity was measured using a Visual Analogue Scale (VAS) to record the response from a standardised short blast of air from a triple syringe. Dentinal hypersensitivity was recorded at baseline, two weeks, three months and six months for all groups. </p><p> <strong>Results</strong></p><p>  Dentinal hypersensitivity reduced significantly (p<0.0001) in both groups DT and DA, in addition the reduction in sensitivity was sustained and continued to improve over a 6-month-period. The greatest reduction in dentinal hypersensitivity was recorded in group DA. </p><p> <strong>Conclusions</strong> </p><p> The results from this study suggest that application of dentine bonding agents, to teeth diagnosed with dentine hypersensitivity provides the greatest improvement in dentine hypersensitivity at 2 weeks and 6 months. This reduction in dentine hypersensitivity is greater than that achieved by the desensitising toothpaste tested and a non-desensitising toothpaste. </p><hr><p></p><p> <strong>Source: </strong>Journal of Dentistry</p><p> <a href="http://www.jodjournal.com/article/S0300-5712(13)00152-8/abstract" target="_blank"><font color="#0000ff">Full Text</font></a></p> Randomised controlled trial, Dental practice, Dentinal hypersensitivity, Dentine bonding agent, Desensitising toothpaste 0 0 http://idai.ir/browse.php?a_code=A-10-32-2177&slc_lang=fa&sid=1 M.
