Randomized Controlled Trial Comparative Study
The anesthetic efficacy of articaine in buccal infiltration of mandibular posterior teeth.
The authors conducted a prospective, randomized, double-blind, crossover study comparing the degree of pulpal anesthesia achieved by means of mandibular first molar buccal infiltrations of two anesthetic solutions: 4 percent articaine with 1:100,000 epinephrine and 2 percent lidocaine with 1:100,000 epinephrine. ⋯ For a mandibular buccal infiltration of the first molar, 4 percent articaine with 1:100,000 epinephrine will result in a higher success rate than will 2 percent lidocaine with 1:100,000 epinephrine, but the duration of pulpal anesthesia will decline over 60 minutes with either formulation.

Comparative Study
Delayed temporomandibular joint pain and dysfunction induced by whiplash trauma: a controlled prospective study.
The Quebec Task Force on Whiplash-Associated Disorders urged for controlled, prognostic studies of symptoms after whiplash trauma. The authors conducted a study that met the design requirements to enhance knowledge about short-term and long-term temporomandibular joint (TMJ) pain, dysfunction or both induced by whiplash trauma. ⋯ Awareness of a significant risk for delayed onset of TMJ symptoms after whiplash trauma is crucial for making adequate diagnoses, prognoses and medicolegal decisions.
