Dexmedetomidine, an alpha-2 adrenergic agonist, offers analgesic and sedative benefits with minimal respiratory depression. Its intranasal (IN) use in oral surgery remains underexplored. This study evaluates the efficacy and safety of intranasal dexmedetomidine (IN DEX) in managing post-operative pain, swelling, sedation and haemodynamic parameters in third molar surgery.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and Methods:<\/jats:title>\n                    <jats:p>A randomised, double-blind, split-mouth controlled trial was conducted in a tertiary dental teaching hospital. Forty-eight healthy patients aged 18\u201340 underwent bilateral mandibular third molar extractions across two sessions. One side received IN DEX (1 \u03bcg\/kg); the contralateral side received a saline placebo. Pain was measured using the Visual Analogue Scale, swelling by five-line facial measurements, sedation by the Modified Observer Assessment of Alertness\/Sedation (OAA\/S) scale, and haemodynamic parameters were monitored perioperatively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Data were analysed using paired\n                      <jats:italic toggle=\"yes\">t<\/jats:italic>\n                      -tests and repeated measures ANOVA.\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; 0.05 was considered statistically significant.

Peak sedation occurred at 40 min without respiratory compromise. IN DEX caused transient hypotension and bradycardia from 20 to 50 min.
