Abstract

Background and Aim: Placebo analgesia has not been investigated extensively in dental settings. Using scaling and root planning (SRP) as a model, this investigation aimed at evaluating the placebo analgesia during SRP.Materials and Methods: One hundred and eighty two patients participated in this double-blind, randomized, controlled clinical trial. Having signed an informed consent form, and obtaining demographic characteristics, all the individuals filled a modified dental anxiety index questionnaire. Based on random blocks, 91 patients were given one placebo capsule 30 minutes before SRP as a potent pain killer, and 91 control subjects received SRP alone. Pain was recorded using a 10 centimeter VAS as well as a 5-point verbal Likert scale (VRS-5) during SRP for each sextant of dentition. Statistical analysis was done by chi-square, Spearman correlation coefficient, and Mann-U-Whitney tests using SPSS software version19.Results: There was no statistical difference between placebo and control groups regarding anxiety, age, sex, pocket depth, and clinical attachment level (P>0.05). VAS and VRS-5 scores were not statistically different between case and control subjects using Mann-Whitney test. Spearman rank test revealed a correlation between the two pain measuring methods (P<0.0001).Conclusion: Within the limitations of this study, the placebo medication is not capable of reducing pain during SRP. to demonstrate the real placebo analgesic effects and complete the results of the present study, more investigations with control of confounding variables are suggested.
