Protocol summary

Summary
Title of this study is the efficacy of low level laser therapy on postendodontic pain in mandibular molars with symptomatic irreversible pulpitis . Inclusion criteria :20-50 years old male or female who needed root canal therapy of mandibular molars exclusion criteria:root canal teeth, no history of drug use ( antibiotic , NSAID , opioid ,corticosteroid) ,analgesic use during 12 hours before treatment, pregnancy, diabetes, malignancy, complicated anatomy ,close canals in graphy,.internal and external resorption,open apex ,periodontal disease , swelling , abscess , lesion in graphy ,sensitive in percussion .90 patiens (45 females, 45 males, mean age: 20-50years) with the demand for endodontic treatment on their permanent mandibular molars with symptomatic irreversible pulpitis )moderate to sever pain )who refered to Zahedan dentistry university and informed consent was obtained prior to the treatments. after endodontic treatment All patients were randomly selected and divided into two groups. In the laser group, In the control group patients received placebo without laser. The patients were blinded to the difference between these groups. All root canal therapies were performed in a single-visit treatment. After the standard chemomechanical preparation of the canals by recieproc(rotary) files. they were obturated using lateral compaction technique and AH26 sealer . laser was given to mandibular molars at a right angle to the buccul and lingual mucosa at the level of the apices for 60 seconds. Application of the laser probe was straight and close to mucosae overlying the apices.In group 1 after treatment The laser unit was a diode laser with a wavelength of 940 nm and output power 200 mv . Pain was evaluated using the Visual Analog Scale and patients were instructed to fill in the questionnaire at 6, 12, 24, and 48 AND 72 hours after root canal treatment.also a packet contains 6 Ipobrophen 400 mg were given to patient and they were advised to use them just in sever pain. The information collected from the questionnaires was about the prevalence and the intensity of post-treatment pain. The intensity of pain was evaluated on a numeric rating scale (Visual Analogue Scale) of 0 for “no pain” to 10 for “unbearable pain”. This method makes it possible to quantify the pain level.
