Brief Summary:
The study composed of sixty patients, each of whom required surgical extraction of a single impacted mandibular third molar under local anaesthesia. The patients were randomly allocated to one of 3 groups of 20 each. The three groups were categorized as Group A (intramuscular dexamethasone), Group B (submucosal dexamethasone) and Group C (control). The objective measurements of facial pain, swelling, and trismus was performed by an independent examiner at baseline (preoperatively), and at days 1, 3, and 7 postoperatively.

Active Comparator: Group A (intramuscular dexamethasone)
In Group A patients, 1 ml of dexamethasone (4mg) administered in the deltoid muscle before commencement of surgical procedure
|
Drug: dexamethasone acetate
1 milliliter of dexamethasone (4milligram) administered in the deltoid muscle before commencement of surgical procedure Procedure: Third molar surgery Surgical access was gained through standard Terrence Ward's incision to raise a full thickness mucoperiosteal flap. Bone removal done around the tooth using a round bur under copious 0.9% normal saline irrigation. The tooth sectioned at cemento-enamel junction whenever required and a Coupland elevator is used to elevate tooth or fragmented tooth out of socket. The socket examined for any debris and sharp bony margins smoothened. The empty socket was irrigated copiously and flap was sutured using three simple interrupted 3-0 black braided silk suture. |
Experimental: Group B (submucosal dexamethasone)
In Group B patients, 1 ml of dexamethasone was administered in submucosa after local anesthesia
|
Drug: submucosal dexamethasone injection
Local anesthesia was achieved using 2% lignocaine hydrochloride and 1:100 000 adrenaline and a standard technique was followed to block Inferior alveolar, lingual and long buccal nerve in all patients. In Group B patients, 1 ml of dexamethasone was administered in submucosa. Investigators divided 1 ml Dexamethasone is into 0.4 milliliter, 0.3 milliliter and 0.3 milliliter parts. Following the local anesthesia, each part of dexamethasone was injected submucosally in the buccal, lingual and retromolar region around the tooth to be extracted. Bone removal done around the tooth using a round bur under copious 0.9% normal saline irrigation and tooth elevated. The flap was sutured using three simple interrupted 3-0 black braided silk suture. All patients were given amoxicillin 500 milligram every 8 hours orally for 5 days, and 500 milligram of paracetamol postoperatively. Procedure: Third molar surgery Surgical access was gained through standard Terrence Ward's incision to raise a full thickness mucoperiosteal flap. Bone removal done around the tooth using a round bur under copious 0.9% normal saline irrigation. The tooth sectioned at cemento-enamel junction whenever required and a Coupland elevator is used to elevate tooth or fragmented tooth out of socket. The socket examined for any debris and sharp bony margins smoothened. The empty socket was irrigated copiously and flap was sutured using three simple interrupted 3-0 black braided silk suture. Drug: Amoxicillin and paracetamol Amoxicillin 500 milligram every 8 hours orally for 5 days, and 500 milligram of paracetamol postoperatively (every 6 hours 1 tablet for 2 days). |
Placebo Comparator: Group C (control)
Group C patients continued without receiving any preoperative medication.

Primary Outcome Measures :
- Assessment of pain [ Time Frame: 1 week ]Postoperative pain was assessed using a visual analog scale (VAS) of 10 point scale with a score of 0 measured "no pain" and 10 correspond to "very severe pain".
- Trismus [ Time Frame: 1 week ]Mouth opening was measured using the maximum distance between the maxillary central incisors and the mandibular central incisors. The difference between sum of post-operative measurements and sum of pre-operative measurements was considered as trismus.
- Facial Swelling [ Time Frame: 1 week ]The evaluation of the facial swelling was performed by modification of Schultze-Mosgau et al method, and the facial measurements involved: 1. Tragus to the oral commissure 2.Tragus to the pogonion. The difference between sum of post-operative facial measurements and sum of pre-operative facial measurements was considered as facial swelling.
