%0 Journal Article %T Comparative Clinical Study of Local Submucosal Corticosteriod Versus Diclofenac Sodium Injections Before Odontectomy of Mandibular Impacted Third Molar %J - %D 2018 %X The aim of this comparative clinical study was to investigate the effects of preoperative injections of Dexamethasone Sodium Phosphate versus Diclofenac Sodium. The study includes 60 patients (age range 16-35) who were randomly distributed into three equal groups. Edema and trismus was measured preoperatively, immediate, 24 h, 2 week, 1 month postoperatively. Pain was assessed by visual analogue scale. Noteworthy reduction in postoperatively complication associated with Dexamethasone group was noticed. Edema & trismus in control group was greater followed by Diclofenac groups then group I. Pain was greater score in control group followed by Diclofenac group then group I %K Preoperative Injection %K Submucosal %K Corticosteriod %K Diclofenac Sodium %K Mandibular Impacted Third Molar %U http://www.sciencepublishinggroup.com/journal/paperinfo?journalid=368&doi=10.11648/j.ijcoms.20180401.14
