About

The aim of the study is to compare the efficacy of the pre-operative administration of Paracetamol and placebo in reducing postoperative pain after routine dental treatment in children. This study will be a prospective, placebo-controlled, randomized, double-blind trial. Patients in need of dental treatment with local anesthesia will take part in the study.

Study group will receive syrup paracetamol 15 min before the dental treatment. Control group will receive placebo syrup, similar in color and viscosity, 15 min before dental treatment. the patient, the treating dentist, and the interviewer will be blind to the medication.

Main outcome measure: one of the main investigators will interview the patient at three time points: immediately at the end of the treatment, one hour after taking the pre-operative analgesic and by phone 2.5 hours after taking the pre-operative analgesic. The patient and his parents will be asked if the child is crying (yes/no), complaining about pain (yes/no), needed a different kind of analgesics after the treatment (yes/no). In addition, each child will describe his ⁄ her feelings regarding postoperative pain, using the Wong-Baker Facial Rating Pain Scale

Patients 5-12 years old, healthy, in need of dental treatment with local anesthesia of Lidocaine 2% with adrenalin 1:100,000 in the Hadassah School of Dental Medicine will take part in the study.

Exclusion criteria: preoperative pain, patients taking analgesics within 5 h prior to the dental treatment, allergic reaction or adverse effect to paracetamol, not available (by phone) at least 2 hours after treatment, patient refuse to drink the syrup.

Study group will receive syrup paracetamol 15 min before the dental treatment. Control group will receive placebo syrup, similar in color and viscosity, 15 min before dental treatment. the patient, the treating dentist, and the interviewer will be blind to the medication.

Data collection: age, gender, type of treatment, type of LA (infiltration /block), time of taking the preoperative analgesic, type of preoperative analgesics ( 1 or 2), time at the end of the treatment and baseline apprehension.
