Tooth Hypersensitivity Clinical Trial
Official title:
A Clinical Study for the Effect of 4th Generation Poly Amido Amine Dendrimer (PAMAM-COOH) Desensitizing Agent on Post-Bleaching Hypersensitivity and Shade Stability of Patients Subjected to Bleaching Treatment.
This study assessed the impact of four desensitizing agents on both color stability and dental sensitivity following a bleaching procedure, spanning from the 24-hour to the 1-year follow-up assessment periods.
Dental bleaching is a temporary treatment with potential adverse effects on dental sensitivity post-procedure. Therefore, the study aimed to evaluate dental color stability and sensitivity over a one-year period following bleaching, utilizing one of four desensitizing agents: PAMAM, MI Paste Plus, Hydroxyapatite and F (ReminPro), and Ultra EZ. The selection of the desensitizing agent was based on a predetermined randomization sequence generated in Microsoft Excel. Color stability was objectively assessed through spectrophotometric analysis, while subjective evaluation was conducted using the Vita Classic shade guide by two external observers not involved in the procedure. Dental sensitivity levels were tracked at various intervals using a visual analogue scale. Baseline measurements for both sensitivity and color stability were taken before the bleaching procedure, with subsequent evaluations at 24 hours, 3 days, 1 week, 1 month, 3 months, 6 months, 9 months, and 1 year post-bleaching. The study involved 60 patients from Ain Shams University seeking dental whitening treatment, divided into four groups based on the randomization sequence. ;
