Dentin hypersensitivity (DH) is a common post-treatment complaint, often managed with fluoride-containing prophylactic pastes. This study evaluated the efficacy of Golchai prophylactic paste in reducing dentin hypersensitivity following manual and ultrasonic SRP.</span></span></span><br> <span style="line-height:200%"><b><span lang="EN"><span style="line-height:200%">Materials and Methods:</span></span></b><span lang="EN"><span style="line-height:200%"> In this randomized, split-mouth, controlled clinical trial, 24 patients with mild-to-moderate periodontitis received four intervention protocols across four quadrants: manual scaling with/without Golchai paste, and ultrasonic scaling with/without the paste. DH was assessed using tactile (Michigan probe) and evaporative (air-syringe) stimuli at baseline, immediately post-SRP, and at 1 day, 1 week, and 4 weeks post-treatment. Pain intensity was recorded using a Visual Analog Scale (VAS). Data were analyzed using Wilcoxon signed-rank tests and Linear Mixed-Effects Models (LMM) </span></span><span style="line-height:200%">(&alpha; = 0.05).</span></span><br> <span style="line-height:200%"><b><span lang="EN"><span style="line-height:200%">Results:</span></span></b><span lang="EN"><span style="line-height:200%"> Immediately post-SRP, no statistically significant differences in sensitivity were observed between scaling methods or between experimental and control quadrants (p > 0.05). LMM analysis for probe-measured sensitivity revealed a significant main effect of Time (P = 0.001). However, neither the scaling method (P = 0.721) nor the application of prophylactic paste (P = 0.979) demonstrated a statistically significant effect on DH reduction.</span></span></span><br> <span style="line-height:200%"><b><span lang="EN"><span style="line-height:200%">Conclusion:</span></span></b><span lang="EN"><span style="line-height:200%"> Dentin hypersensitivity following SRP decreases progressively over time as part of the natural healing process. Manual and ultrasonic instrumentation are comparable regarding post-operative sensitivity. The adjunctive use of Golchai prophylactic paste&mdash;a conventional fluoride-containing agent lacking specific bioactive desensitizers does not provide an additional measurable reduction in hypersensitivity compared to scaling alone.</span></span></span></span></span></div> 0 0 http://cofs.khuisf.ac.ir/browse.php?a_code=A-10-1-87&slc_lang=en&sid=1 Mitra Ganji Kahaki 10031947532846001503 10031947532846001503 No Faculty of Dentistry, Isf.C., Islamic Azad University, Isfahan, Iran Samane Soltany 10031947532846001504 10031947532846001504 Yes Department of Periodontics, Faculty of Dentistry, Qom University of Medical Sciences, Qom, Iran Leila Khodadadifard 10031947532846001505 10031947532846001505 No Department of Periodontics, Faculty of Dentistry, Qom University of Medical Sciences, Qom, Iran Mohammad Aghaali 10031947532846001506 10031947532846001506 No Department of Family and Community Medicine, Faculty of Medicine, Qom University of Medical Sciences, Qom, Iran
