Efficiency of Diode Laser Activated Irrigation on Healing of Periapical Tissues

Not Applicable

Completed

• Conditions: Periapical Diseases
• Interventions: Device: Diode laser; Other: Placebo

• Registration Number: NCT04311905
• Lead Sponsor: Ain Shams University

Brief Summary

Study is a Randomized clinical trial conducted at Endodontic department- Ain Shams university Cairo. Egypt. 24 eligible patients were selected and included in the study to compare healing ability of diode laser activated irrigation versus conventional root canal treatment using CBCT

Detailed Description

Sample size is 24 , 24 Patients were randomly distributed in 2 groups , one group of patients received laser activated irrigation LAI during root canal treatment and the other group received no treatment just conventional RCT. • Patients were equally divided into 2 groups (n=12 in each group ) The study in a Single blinded RCT , Numbers for patients will be generated and distributed randomly in a table on an Excel sheet, and in front of each number either a letter (C) for control or (I) for intervention will be typed After patients were selected in the study they will be asked to fill in a consent form , that states that they are part of a clinical trial and that they may or may not receive a laser activated irrigation Group A LAI :Disinfection were done by using 5 ml of 2.5% sodium hypochlorite irrigation for 1 minute. Irrigation will be performed with a 30-gauge needle side vented The irrigation needles were introduced passively up to 2 mm away the working length. After irrigation Laser treatment will be performed with a diode laser, at a wavelength of 980 nm with a repeated pulse mode using a pulse duration of 5sec per canal and a pulse interval of 0.2 ms. The laser irradiation were delivered for 1 minute into the canal up to 1 mm short of the working length, with circling movements from the apical part moving towards the coronal part Group B : received mock laser intervention , conventional Root canal treatment with 2.5% sodium hypochlorite CBCT was taken pre-operative and another one was taken after 12 month , both volumetric and linear measurements were calculated
