Upper third molar causing mechanical obstruction of mouth opening: A true but rare cause of trismus

AbstractSupernumerary teeth in the upper third molar region are relatively common but cases in the lower jaw are rare. In his survey of supernumerary teeth Stafne (1932) saw 131 upper but only 10 lower fourth molars. The following is a report of a single supernumerary tooth in the lower third molar region.

INTRODUCTION: The extraction of the upper third molar is a simple and common procedure in Oral and Maxillofacial Surgery daily practice. Infection, facial swelling, trismus, wound dehiscence, root fracture, oroantral fistula, iatrogenic displacement, fracture of the maxillary tuberosity are some of the complications that can occur during third molar extraction.CASE DESCRIPTION: In this article, an unusual fracture of the pterygoid process during upper third molar extraction and a minimally invasive technique for treatment are described.CONCLUSION: It is important to recognize the fracture and not remove the fragment before a complementary image exam, it will guide the type of treatment that should be use.

Postoperative Administration

Aim. To evaluate the effect of preoperative versus postoperative administration of oral Dexamethasone on postoperative complications including pain, edema, and trismus following lower third molar surgery.Methods. 24 patients were divided into two equal groups receiving 8 mg Dexamethasone orally, one group one hour preoperatively and the other group immediately after surgery. Pain was measured using VAS, edema was measured using a graduated tape between 4 fixed points in the face, and the mouth opening was measured using a graduated sliding caliper.Results. In this study pain and trismus records were similar and statistically nonsignificant in both groups. The results had proven that preoperative administration was superior when compared to postoperative administration regarding edema (0.002).Conclusions. Preoperative oral administration of 8 mg Dexamethasone was superior to the postoperative administration of the same dose concerning edema after lower third molar surgery.

Abstract We compared the buccal infiltration of 4% articaine with 1 : 100,000 or 1 : 200,000 epinephrine without a palatal injection for the extraction of impacted maxillary third molars with chronic pericoronitis. This prospective, double-blind, controlled clinical trial involved 30 patients between the ages of 15 and 46 years who desired extraction of a partially impacted upper third molar with pericoronitis. Group 1 (15 patients) received 4% articaine with 1 : 100,000 epinephrine and group 2 (15 patients) received 4% articaine with 1 : 200,000 epinephrine by buccal infiltration. None of the patients in group 1 reported pain, but 3 patients in group 2 reported pain, which indicated a need for a supplementary palatal injection. The palatal injections were all successful in eliminating the pain. Two additional patients in group 2 experienced pain when the suture needle penetrated their palatal mucosa. Based on these results, 4% articaine with 1 : 100,000 epinephrine was found to be more effective for the removal of upper third molars in the presence of pericoronitis than 4% articaine hydrochloride with 1 : 200,000 epinephrine when only a buccal infiltration was used.
