تأثیر تزریق دگزامتازون در عضله‌ی ماستر بر عوارض بعد از جراحی دندان مولر سوم نهفته‌ی فک پایین

نوع مقاله : مقاله‌های پژوهشی

چکیده

مقدمه: جراحی دندان‌های عقل نهفته، با وارد آوردن تروما به نسوج نرم و سخت، تورم درد و تریسموس را به دنبال دارد. هدف از این مطالعه، بررسی اثر تزریق دگزامتازون در عضله‌ی ماستر بر عوارض بعد از جراحی به دنبال جراحی دندان مولر سوم نهفته‌ی فک پایین بود.
مواد و روش‌ها: این مطالعه به صورت کارآزمایی بالینی و بر روی 43 بیمار سالم انجام شد. در گروه آزمایش، تزریق 4 میلی‌گرم از دگزامتازون داخل عضله‌ی ماستر از طریق Intrabuccal approach صورت گرفت و گروه شاهد نیز هیچ‌گونه کورتیکو استروییدی دریافت نکرد. داده‌ها با استفاده از آزمون آماری t-test تجزیه و تحلیل شدند (0/05 = α). 
یافته‌ها: بین میزان درد و التهاب در گروه با تزریق دگزامتازون و گروه شاهد در همه‌ی زمان‌ها به طور معنی‌داری کمتر بود (0/001 > p value). همچنین از نظر میزان تریسموس بین دو گروه آزمایش و شاهد، تفاوت معنی‌داری وجود داشت (0/001 > p value). 
نتیجه‌گیری: تزریق دگزامتازون با کاهش مدیاتورهای التهابی در عضله‌ی ماستر، تأثیر مثبت و معنی‌داری بر کاهش میزان درد، ادم و تریسموس ناشی از عمل جراحی مولر سوم نهفته فک پایین دارد.
کلید واژه‌ها: دگزامتازون، عضله‌ی ماستر، جراح، دهان، دندان مولر سوم.

Effect of Preoperative Single Dose Dexamethasone Injection in Masseter Muscle on Postoperative Sequelae Following Lower Impacted Third Molar Surgery

چکیده [English]

Introduction: The surgical removal of impacted lower third molars involves trauma to soft and bony tissue and can result in pain, swelling and trismus. The purpose of this study was to evaluate the efficacy of dexamethasone, as a single 4 mg dose injected into the masseter muscle prior to extraction of impacted lower third molars on theses postoperative sequelae.
Materials and Methods: This prospective, randomized clinical research consisted of 43 healthy patients. The study group received 4 mg dexamethasone into the masseter muscle via intrabuccal approach immediately before starting the procedure while the control group received no corticoid. 7 days after surgery. Data were analyzed using t-test (α = 0.05).
Results: The patients administered dexamethasone showed superior results after surgery in terms of oral aperture, pain and all the facial swelling parameters, with statistically significant differences versus the controls (p value < 0.001). Also there was statistically significant difference in terms of patients trismus between case and control groups (p value < 0.001).
Conclusion: The results obtained showed that 4 mg of dexamethasone injected into the masseter muscle in the immediately before starting the procedure significantly reduces swelling, trismus and pain.
Key words: Dexamethasone, Masseter muscle, Surgery, Oral, Molar, Third.
