The study will be a parallel, placebo-controlled, triple-blinded, randomized clinical trial. A total of 66 healthy children aged 5-8 years requiring the placement of a stainless steel crown will be selected from Pediatric Dentistry and Dental Public Health Department, Faculty of Dentistry, Alexandria University, Egypt. The children will be randomly allocated into three groups according to the type of pre-emptive solution used. Group I will receive ibuprofen, group II will receive paracetamol, while group III (control) will receive a placebo solution. Children will self-report their level of pain using a Visual analogue scale (VAS) and/or a Facial pain scale (FPS) after local anesthesia administration, immediately after the cementation of the stainless steel crown, and 2, 6 and 24 hours post-operatively. Children's baseline anxiety and parental anxiety will also be assessed.
The aim of this study is to evaluate the effectiveness of pre-emptive analgesia using ibuprofen and paracetamol on reducing post-operative pain following the placement of stainless steel crowns on primary molars compared to placebo
