Conditions

Symptomatic Irreversible Pulpitis and Symptomatic Apical Periodontitis

Keywords

Ultrasonic, Diode laser, Irrigation, Activation

Brief summary

The study is designed to determine whether activation of the irrigant using ultrasonic or diode laser technology can reduce postoperative pain and influence Substance P levels compared with conventional needle irrigation. The findings may contribute to establishing evidence-based irrigation activation protocols for improving patient comfort following root canal treatment.

Interventions

PROCEDUREdiode laser activation irrigation

This group will receive diode laser-activated irrigation using a 940-nm diode laser (Epic X, BIOLASE).

This group will receive ultrasonic-activated irrigation using the Ultra X ultrasonic activation device (Eighteeth).

Inclusion criteria

Inclusion 1. Healthy patients ranging between 18 and 65 years in age . 2. Patients that experienced moderate-to-severe pain (4-10)-represented on a visual analogue scale (VAS). 3. Having a mandibular single rooted premolar tooth with vital pulp. 4. Having the symptoms of symptomatic irreversible pulpitis and apical periodontitis. Exclusion 1. Patients who were pregnant or lactating. 2. Patients taking analgesic or anti-inflammatory drugs within the least 12 hours. 3. Teeth with calcified root canals, resorptions. 4. Previously root canal treated. 5. severe damage and associated traumatic occlusion. 6. Teeth with open apices. 7. Presence of periodontal pockets \>3 mm in the affected tooth.

Design outcomes

Primary

MeasureTime frameDescription
Postoperative pain12,24,48 hoursPostoperative pain will be assessed using a Visual Analog Scale (VAS) following conventional root canal treatment. Pain will be recorded at baseline before treatment and at predetermined postoperative time points to compare pain levels among the conventional needle irrigation, ultrasonic-activated irrigation using Ultra X, and 940-nm diode laser-activated irrigation using Epic X groups.

Secondary

MeasureTime frameDescription
Substance P levelup to 24 hoursSubstance P levels will be measured using an enzyme-linked immunosorbent assay (ELISA) to evaluate the effects of conventional needle irrigation, ultrasonic-activated irrigation using Ultra X, and 940-nm diode laser-activated irrigation using Epic X on Substance P levels. Measurements will be performed at the time points specified in the study protocol, and the results will be compared among the three study groups.
