The primary purpose of this study is to evaluate the clinical effectiveness of two commercially available fluoride varnishes.\n\nThe main questions this study aims to answer are:\n\n* Does Clinpro Clear® (aqueous base, 9,500 ppm NaF) lead to a greater reduction in dentin hypersensitivity compared with Duraphat® (rosin\u002Fresin base, 22,600 ppm NaF)?\n* Do these varnish formulations improve oral health-related quality of life and patient satisfaction?\n\nResearchers will compare a single application of Duraphat® with a single application of Clinpro Clear® to assess differences in hypersensitivity reduction, quality-of-life outcomes, and patient satisfaction.\n\nParticipants will:\n\n* Receive one application of either Duraphat® or Clinpro Clear® under standardized clinical conditions.\n* Complete baseline and post-treatment evaluations, including:\n* Dentin hypersensitivity intensity using a visual analogue scale (VAS)\n* Air-blast response using the Schiff scale\n* Oral health-related quality of life using the OHIP-14\n* Patient satisfaction using the CSAT survey",[27,28],"Hypersensitivity Dentin","Fluoride Varnishes",[30,31,32,33,34,35,36],"Dentin hypersensitivity","Fluoride varnishes","Visual analogue scale (VAS)","Schiff scale","OHIP-14","Desensitizing agents","Aqueous fluoride varnish","RECRUITING","2026-05-29",{"date":40,"type":41},"2026-06-02","ACTUAL",{"date":43,"type":41},"2025-12-04",{"date":45,"type":21},"2026-08-30",{"name":47,"class":48},"University of Concepcion, Chile","OTHER",""]
