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.&lt;/span&gt;&lt;/p&gt;
