Brief summary

In endodontics, various irrigation solutions are used to achieve antibacterial efficacy within the root canal. The antibacterial effect of curcumin-containing root canal solutions, when combined with photodynamic therapy, has been demonstrated in several studies. However, no research has specifically examined their effect on postoperative pain. The aim of this study is to investigate the impact of using a curcumin solution in combination with photodynamic therapy as the final irrigation solution on postoperative pain.

Detailed description

Fifty patients were randomly assigned to two groups using a web-based program, according to the selected final irrigation procedure: curcumin-photodynamic therapy or a control group (routine root canal final irrigation with NaOCl and EDTA). The teeth will be isolated with a rubber dam, and access cavities will be created. After root canal preparation, the final irrigation procedure will be performed. Root canal treatments will then be completed, and the patients' postoperative pain levels will be recorded using follow-up forms.

Interventions

OTHERCurcumin with photodynamic thearpy

root canals will irrigated with final irrigation procedure: curcumin+photodynamic therapy. The teeth will be isolated with a rubber dam, and an access cavity will be created. After root canal preparation, the final irrigation procedure will be performed. Root canal treatments will be completed, and the patients' postoperative pain levels will be recorded using follow-up forms.

OTHERControl group

root canals will irrigated with routine root canal final irrigation with NaOCl and EDTA. The teeth will be isolated with a rubber dam, and an access cavity will be created. After root canal preparation, the final irrigation procedure will be performed. Root canal treatments will be completed, and the patients' postoperative pain levels will be recorded using follow-up forms.

Design outcomes

Primary

MeasureTime frameDescription
postoperative pain levelsone weekpostoperative pain levels will be describe using the visual analog scale (VAS). The VAS was classified using the following scale \[15\]: no pain (0); mild pain (1-3); moderate pain (4-6), and severe pain (7-10).

Secondary

MeasureTime frameDescription
dependent variables-sexone weekThe patients' genders (female or male) will be recorded, and their relationship with postoperative pain will be statistically analyzed.
dependent variable-ageone weekThe patients' ages will be recorded as numbers, and their relationship with postoperative pain will be statistically analyzed.
dependent variables-teeth numberone weekThe patients' tooth numbers will be recorded, and their relationship with postoperative pain will be statistically analyzed.
dependent variables-smoking habitone weekThe patients' smoking habits will be recorded as either yes or no, and their relationship with postoperative pain will be statistically analyzed.
