To establish a quantitative sensory testing (QST) profile in the trigeminal (V) area and test for site and gender differences in healthy humans. ⋯ Application of this standardized QST protocol may allow for a better understanding of the underlying mechanisms from somatosensory phenotypes and provide basic information for the study of sensory dysfunctions in the V area.

Randomized Controlled Trial Multicenter Study Comparative Study
Efficacy of topical 1% lidocaine in the symptomatic treatment of pain associated with oral mucosal trauma or minor oral aphthous ulcer: a randomized, double-blind, placebo-controlled, parallel-group, single-dose study.
To determine the efficacy in pain reduction of a topical 1% lidocaine compared to a placebo cream in patients with oral mucosal lesions due to trauma or minor oral aphthous ulcer. ⋯ A significant reduction in pain intensity occurred after application of 1% lidocaine cream and was significantly greater than that with the placebo cream. Taking into account the study's limitations, this product seems safe to use.

To study the effect of diet hardness on condylar cartilage thickness, extracellular matrix composition, and expression of matrix metalloproteinase (MMP) -3, -8 and tissue inhibitor of metalloproteinase-1 (TIMP-1), by using immunohistochemical and morphometric methods. ⋯ The results show that a soft diet during growth increases collagenolytic activity and may increase the vulnerability of condylar cartilage.

Review Meta Analysis
Effectiveness of low-level laser therapy in temporomandibular disorders: a systematic review and meta-analysis.
To assess the scientific evidence on the efficacy of low-level laser therapy (LLLT) in the treatment of temporomandibular disorders (TMD). ⋯ Currently, there is no evidence to support the effectiveness of LLLT in the treatment of TMD.
