A light microscopical study on the structure of traumatic neuromas of the human lingual nerve.
To determine the morphologic characteristics of traumatic neuromas resulting from damage to the lingual nerve during the surgical removal of lower third molar teeth. ⋯ Damage to the lingual nerve during third molar removal results in marked changes to the fascicular pattern and sometimes the presence of chronic inflammation in the injured nerve. These changes could contribute to the altered electrophysiological properties of axons trapped within traumatic neuromas, but we found no significant differences between the specimens studied from patients with or without symptoms of dysesthesia.

Randomized Controlled Trial Clinical TrialEfficacy of articaine and lidocaine in a primary intraligamentary injection administered with a computer-controlled local anesthetic delivery system.
The purpose of this prospective, randomized, double-blind study was to compare the anesthetic efficacy of the intraligamentary injection of 4% articaine with 1:100,000 epinephrine and of 2% lidocaine with 1:100,000 epinephrine, administered with computer-controlled local anesthetic delivery system, in mandibular posterior teeth. ⋯ The efficacy of 4% articaine with 1:100,000 epinephrine was similar to the efficacy of 2% lidocaine with 1:100,000 epinephrine for intraligamentary injections.

Analysis of tumor necrosis factor-alpha, interleukin-6, interleukin-1beta, soluble tumor necrosis factor receptors I and II, interleukin-6 soluble receptor, interleukin-1 soluble receptor type II, interleukin-1 receptor antagonist, and protein in the synovial fluid of patients with temporomandibular joint disorders.
To measure the levels of various cytokines, cytokine receptors, and cytokine antagonists in the synovial fluid of patients with temporomandibular disorders (TMD) and to determine the correlations among these expression levels. ⋯ TNF and sTNFRs in the synovial fluid of patients with TMD may be important in the pathogenesis of these disorders.

Piercing is popular among young people, who view this practice as a sign of marginality, beauty, or group identity. The complications of lingual piercing include infection, pain, bleeding, edema, inhalation, dental trauma, contact lesions, and oral interferences. The objective of this case report is to present a case of lingual piercing in which the piercing had become partially embedded in the interior of the tongue.

Randomized Controlled Trial Clinical TrialPreemptive rofecoxib and dexamethasone for prevention of pain and trismus following third molar surgery *.
Objective The goal of this preliminary randomized prospective clinical trial was to compare the analgesic efficacy and the reduction in trismus of preoperative rofecoxib, intraoperative dexamethasone, and both rofecoxib and dexamethasone following third molar extraction surgery. Study design Thirty-five subjects requiring surgical removal of at least 1 partial bony impacted mandibular third molar were invited to participate in this double-blind and double-dummy placebo-controlled clinical trial. Subjects were randomly assigned into 1 of 4 treatment groups: (1) placebo po preoperatively and placebo IV intraoperatively; (2) rofecoxib 50 mg po preoperatively and placebo IV intraoperatively; (3) placebo po preoperatively and dexamethasone10 mg IV intraoperatively; and (4) rofecoxib 50 mg po preoperatively and dexamethasone 10 mg IV intraoperatively. ⋯ The group receiving the combination of rofecoxib and dexamethasone showed a decrease in interincisal opening of 23.7% of baseline ( P < .05 vs placebo). Conclusions The results of this trial indicate that the use of intraoperative dexamethasone is an effective therapeutic strategy for limiting trismus following surgical removal of impacted third molars. The combination of preoperative rofecoxib 50 mg and intraoperative dexamethasone 10 mg was most effective in minimizing pain and trismus following third molar surgery.
