DOUBLE BLIND RANDOMIZED CLINICAL TRIAL ON ARNICA MONTANA 6CH IN MUSCLE THERMAL CHANGES BY ISOMETRIC STRESS IN PATIENTS WITH TMD AFTER ENDODONTIC PROCEDURES (Atena Editora)

Abstract

The Arnica montana 6CH is a medicine for general muscular alterations and by isometric and thermography is a resource for the diagnosis of these alterations.

Goal: The objective of this double-blind randomized clinical study was to verify the role of Arnica montana 6CH in the thermographic muscle changes of patients submitted to isometric stress in prolonged sessions of endodontics.

Materials and methods: 70 patients were selected after a positive response to the RDC questionnaire (Research Diagnostic Criteria for Temporomandibular Disorder) for confirmation of TMD (Temporomandibular Muscular Dysfunction). Masseter and temporalis muscle temperatures on both sides were taken and recorded before and after the first endodontic consultation. Arnica montana 6CH was randomly prescribed to 35 patients, constituting group I, and placebo to 35 patients of group II. In the second endodontic consultation, a new measurement of muscle temperatures was performed and clinical evaluation was performed with the crossing of data from the RDC/TMD questionnaire. Data were tabulated and analyzed.

Statistical analysis: Student's t test was used for paired samples, significant at the level of ≥ 0.05%.

Results: The average decrease in comparative temperature between G I and G II was 0.6ºC, and in the GI group (Arnica montana 6CH), the lower thermal results were statistically significant compared to GII (p=0.0022). Regarding the anamnetic data from the RDC questionnaire, 86% of the individuals in the GI had lower pain rates at the second consultation, compared with 22% in the GII.

Conclusion: The medicine Arnica montana 6CH was shown to be effective in preventing muscle changes and clinical symptoms resulting from isometric efforts with a statistically significant difference (p=0.0022).
