The Effect of Ibuprofen, Paracetamol versus Placebo on Pain during Local Anesthetic Injection and Following Dental Extraction in Primary Molars: A Randomized clinical trial

1\. Diagnosis: 1. Diagnostic chart will be filled with personal, medical and dental history. DMF and def. 2. Clinical examination (intra oral and extra oral) will be done by mirror and probe to assess the inclusion criteria. All materials will be packaged in sterilizations wraps and autoclave following the required bio safety standards. 2\. Intervention: Experimental Groups: Group 1: Ibuprofen suspension (Ibufen®, 100 mg/5 mL; fruit flavored, orange colour, Abbott). Group 2: Paracetamol (Calpol™, 250 mg/5 mL; fruit flavored, orange color, GlaxoSmithKline). Comparative Group: Group 3: A fruit-flavored orange color placebo solution. Clinical procedure: 1. The drugs in all of the groups will be prepared in a fruit-flavored solution of the same color and scent. 2. Patients will be blind to one of the three pre-treatment drug groups. 3. Containers of each solution will be prepared and number-coded with the slips of paper by the assistant supervisor. The containers will be the same for all treatment groups except for the number coded with slips of paper. 4. Both the researcher and the child/parent will be blind to the content of the container. 5. The assigned solution will be taken by the patient at various times before administration of the local anesthetic agent. Ibuprofen 30 min before injection of local anesthesia paracetamol 60 min before injection of local anesthesia Placebo solution 60 min before injection of local anesthesia 6. The time of the preoperative solution administration will be recorded on the data sheet. 7. Topical anesthesia in the form of benzocaine gel 20% will be applied to the dried mucosa. All the children will be given 2% lidocaine with a 1:80,000 epinephrine injection for local anesthesia sufficient for obtaining adequate anesthesia. 8. All teeth will be extracted with a minimum of surgical trauma in an uncomplicated fashion. Recording data 1. Pain scores will be recorded in the Pediatric Dental Clinic using a five-face scale that had been previously validated. 2. This scale has shown good construct validity as a self-report pain measure. It measures an affective dimension of a child's pain experience after injection and teeth extraction and is used in children aged 7-12 years. 3. It is easy to use and giving consistent scores from 0 to 4. It can be used for the subjective evaluation of feelings after the performance of painful dental procedures. 4. The child will be shown to a set of five cartoon faces with varying facial expressions ranging from a smile/laughter to tears. The scores given are: (0) No sign of pain. (1) Mild pain. (2) Moderate pain. (3) Severe pain. (4) Very severe pain.
