PULPITIS

Spearman's correlation test showed a significant positive correlation between the anxiety score of patients before treatment with their preoperative (rho = 0.387, 
Comparison of patients with pain score 0 between the two groups at each time point by Fisher's exact test revealed no significant difference (Regarding sensitivity to percussion before treatment, 21 patients were evaluated (since the results of the percussion test had been recorded for only 21 patients); out of which, 5 were sensitive and 16 were not sensitive to percussion. The Two out of 32 patients in the ibuprofen tablet group reported gastrointestinal problems in the form of mild pain. Also, one patient in the KTP group experienced slight redness and itchiness when used the first KTP. Since he wanted to continue using the patch, he applied the next patch on another area with no problem.Assessment of the pain score over time showed a nonlinear trend of reduction in pain over time in both groups (Although the mean preoperative pain score was higher in the KTP group, the difference between the two groups was not significant (The interaction effect of time and medication was not significant at any interval in any group (GEE was applied to assess the effect of type of tooth on postoperative pain and showed that although patients with a second molar with irreversible pulpitis had higher postoperative pain than those with a first molar with irreversible pulpitis (GEE was also used to analyze the effect of gender, and it indicated that although females in both groups had a higher pain score than males (
