Clinical comparative study of the effectiveness of two dosages of Dexamethasone to control postoperative swelling, trismus and pain after the surgical extraction of mandibular impacted third molars.

Purpose: The aim of this study was to evaluate the effect of two different concentrations (4 and 8 mg) of dexamethasone to decrease the swelling and trismus after the surgical extraction of mandibular impacted third molars.

Methods: This randomized clinical trial comprised thirty (30) adult patients of both genders with no local or systemic problems, with bilateral impacted lower third molars in similar position, where surgical extraction had been indicated. They were given 4 mg and 8 mg of dexamethasone 1 hour before the surgical procedure at the first or second surgery.

Patient's perception of the events during and after osteogenic alveolar distraction.

Objective: The aim of the study was to evaluate the patient s perception of the events during and after an osteogenic alveolar distraction (OAD) procedure

Materials And Methods: A total of fifty-five (55) osteogenic alveolar distraction (OAD) procedures were performed in fifty (50) patients, who then were asked to answer ten (10) questions related to the treatment. Six (6) questions made reference to predefined values in a Visual Analogical Scale (VAS), three (3) questions could be answered by a predetermined answer, and only one (1) question had a free answer.

Results: In 76% of cases, the patient s description of the sensation felt during the surgery was good and bearable; 84% of the patients didn t feel pain after surgery.

Facial nerve paralysis after impacted lower third molar surgery: a literature review and case report.

With multiples etiologies, these included trauma, tumor formation, idiopathic conditions, cerebral infarct, pseudobulbar palsy and viruses. FNP during dental treatment is very rare and can be associated with the injection of local anesthetic, prolonged attempt to remove a mandibular third molar and subsequent infection.

Conservative treatment protocol of odontogenic keratocyst: a preliminary study.
