Impact of laser disinfection and passive ultrasonic irrigation on postoperative pain in single visit root canal therapy
Keywords:
PUI, disinfection, lasers, root canal therapyAbstract
Introduction: Postoperative endodontic pain is common. 3 to 58% of patients had post-op pain. Canal microbes are tough to eliminate. No irrigant meets all the perfect irrigant characteristics. Methods: In Kanpur, India, 46 participants were enrolled in this randomised clinical trial from January to June 2022. Department of Conservative Dentistry and Endodontics conducted the study. Local anaesthetic (1:2,000 lignocaine with adrenaline) was followed by rubber dam isolation and access cavity preparation. Teeth were cleaned and shaped. Patients were divided into two groups using a coin flip. Group A employed a 2 W 810 nm diode laser for laser disinfection. In Group B, sodium hypochlorite (NaOCl) was ultrasonically agitated. After a final treatment with saline, composite resin was used for obturation and post-endodontic restoration. A blinded assessor rated post-endodontic treatment after 6 hours, 24 hours, 48 hours, and 7 days. SPSS 20.0 was used to gather and analyse the data after utilising Pearson's Chi-square test with 5% significance. Results: 25 men and 19 women among 44 patients. 10 patients were 40-60, 28 were 30-40, and 12 were 18-29. No statistically significant difference was seen between PUI and laser disinfection in single visit root canal therapy (p=0.086).
