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 assess Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) Axis II variables in an initial psychosocial screening and as a part of biopsychosocial subtyping of Finnish referral patients with TMD pain for adjunct multidisciplinary assessment. ⋯ The Finnish RDC/TMD Axis II was found reliable in initial TMD pain patient screening and with further biopsychosocial assessment identified three main TMD subtypes, two with compromised psychosocial profiles for adjunct multidisciplinary assessment.

To translate the Pictorial Representation of Illness and Self Measure (PRISM) instrument from German to Portuguese (Brazilian) and adapt it to the Brazilian cultural context, and then assess its reliability and validity in orofacial pain patients. ⋯ The cross-cultural adaptation process of PRISM was successful and the adapted version offers reliable and valid psychometric properties in the Brazilian context.

Comparative Study
Development of labeled magnitude scales for the assessment of pain of dentin hypersensitivity.
To develop and test labeled magnitude (LM) scales that are sensitive to variations in pain associated with dentin hypersensitivity (DH). ⋯ LM scales were shown to provide some advantages compared to standard VAS when used to evaluate DH-associated pain. These advantages may be generalized to other low-level pain conditions.

Research efforts have been directed to determine whether temporomandibular disorder (TMD) patients have psychological problems and whether these factors influence treatment outcome. Because there is no consensus about the best way to quickly assess psychological problems in TMD patients, this study was designed to evaluate a simple method for identifying psychological factors that may need to be addressed as part of a comprehensive treatment program. ⋯ Sensitivity, specificity, and ordinal rank-based association model analyses showed moderate to strong associations between patients' ratings and the corresponding psychometric measures. These results provide evidence that the brief self-ratings of psychological factors utilized in this study may be a useful first step to screening for psychological difficulties in TMD patients.
