Actual date on which the first participant was enrolled.

This study is investigating how to reduce common side effects such as pain, swelling, and difficulty opening the mouth after surgery to remove impacted lower wisdom teeth. The focus is on using a steroid called dexamethasone, which is injected directly into specific muscles around the jaw area immediately after the tooth is removed. The study involves patients who are 18 years or older and have wisdom teeth that are difficult to extract. By finding out which injection site is more effective, this research aims to improve recovery outcomes for people undergoing similar dental procedures. Participants in the study will have their impacted wisdom teeth removed two weeks apart. After each tooth extraction, dexamethasone is injected into different areas of the jaw to compare effects. The study will assess pain levels, swelling, and mouth opening ability through various measurements and questionnaires. These assessments will take place at multiple times, including the day of the procedure and on the 3rd and 7th days afterward. Although complications are rare, potential risks include allergic reactions, infection, or temporary numbness. The study is one month long for each participant, and it is important to attend follow-up appointments and report any issues during the study.

Treatment Groups
Study Objectives

2 intervention groups are designated in this study

This study does not include a placebo group 

Treatment Groups

Group I

Active Comparator
Group 1 (Masseter Injection) (n=20): 8 mg IM dexamethasone injection into the masseter muscle of the patients in this group was performed. Dexamethasone injection in group 1 was made into the masseter muscle. Injection; The margo anterior of the mandible was palpated and horizontally parallel to the occlusal level of the mandibular second molar tooth and 1 cm behind the margo anterior towards the mandibular ramus. Bone contact was not taken during the injection and the injection was made by taking negative aspiration.Similar to the mandibular anesthesia technique

Group II

Active Comparator
Group 2 (Pterygomandibular Space Injection) (n=20): 8 mg IM dexamethasone injection into the pterygomandibular cavity of the patients in this group was performed. The injection given to Group 2 was directed to the region between the margo anterior of the mandible and the raphe pterygomandibularis, 1 cm above the occlusal level of the mandibular 2nd molar tooth, and the direction of the syringe from the incisal top of the opposing mandibular canine tooth to this region, and then entering the pterygomandibular cavity. Bone contact was not taken during the injection and the injection was made by taking negative aspiration
