Abstract
The efficacy of diode laser and 1% chlorhexidine varnish, Cervitec Plus, on dentinal sensitivity in patients with chronic periodontitis is of interest to dentists. Among the patients who had developed hypersensitivity after scaling and root planing (SRP), sixty were chosen and divided into two big groups. They underwent either the application of the Cervitec Plus varnish or were treated under diode laser treatment. The two primary treatment groups were subdivided to compare the outcome regarding single and multiple applications for each treatment. The findings were that both diode laser treatment and chlorhexidine varnish offered symptomatic relief when combined with SRP. However, patients receiving diode lasers showed a higher reduction in sensitivity scores, primarily upon repeated applications. Thus, although both treatments are effective, diode laser treatment may present better relief for dentine hypersensitivity cases of chronic periodontitis, especially on repeated applications.
