Abstract
INTRODUCTION: The removal of impacted teeth is one of the most common procedures performed by oral and maxillofacial surgeons. Reduction of discomfort post-operatively and efficient local anesthesia are imperative for success in surgical practice. At sub-anesthetic doses, ketamine has a noticeable analgesic action, which can be used to supplement local anesthesia with minimal side effects. AIM: To assess the efficacy of low-dose ketamine as an adjunct to local anesthesia in the management of pain, swelling and trismus after surgical removal of impacted mandibular third molars. MATERIALS AND METHODS: Twenty five patients with bilaterally symmetrical impacted mandibular third molars requiring surgical removal under local anesthesia were selected for the controlled clinical study. The third molar sites of all patients enrolled in the trial were randomly assigned into 2 groups: Local Anesthesia (Lignocaine) Alone [LAA] and Local Anesthesia plus ketamine [LAK]. 5ml of local anesthetic (Lignocaine Hydrochloride 2% with epinephrine 1:100,000) was injected in the 'LAA' group while the 'LAK' group received 5ml of local anesthetic plus 0.2mg/kg ketamine. Patients were blinded to the solution used and the operator recorded the group (LAA or LAK) and the respective site (Right or Left) for analysis. Bilaterally symmetrical impacted mandibular molars were removed at an interval of 15 days. RESULTS:Facial swelling on post-operative days was significantly lower in the LAK group than in the LAA group (p<0.05). The pain scores on the VAS were significantly higher in the LAA group than in the LAK group (p<0.05). CONCLUSION: The role of ketamine in low doses as an analgesic and anti-inflammatory is evident in our study. The combination of a local anesthetic and sub-anesthetic doses of ketamine injected for surgical removal of impacted third molars provides good local anesthesia while alleviating post-operative sequelae for the patient by providing a degree of post-operative analgesia with less swelling.
