Abstract The efficiency of TPI for the treatment of MTrPs is well documented in the literatures. Nevertheless, the comparison between various injectable solutions is paramount with a view for determining the most effective one. Thus, it was the aim of this study to assess and compare the treatment effects of dextrose prolotherapy, saline, and mepivacaine injections for deactivating MTrPs within the jaw muscles. A total of 60 patients with active MTrPs within the jaw muscles were included in this prospective study. The patients were randomly allocated to one of three equal groups using computerized sequence generation. The mean age of patients was 33.6, 34.35 and 35.15 years and the mean duration of symptoms was 17.06, 8.61 and 21.67 months in the dextrose, saline and LA groups respectively. All patients were females except one male in the dextrose group. For all patients, three consecutive weekly rounds of treatment were performed; 3 treatment sessions at an interval of 2 days in the first week, 2 treatment sessions at an interval of 3 days in the second week and one treatment session at the end of the third week. Before treatment and at one week and 12 weeks after the end of the treatment sessions, current and worst pain severity was assessed by visual analog scale (VAS), degree of tenderness at the trigger points (PPT) by algometry, and the MMO. There was a significant improvement in current and worst pain severity at the 1st and 12th post-injection weeks compared to those at the baseline in all the three groups. The improvement in TrP tenderness as evident by the increase in PPT values compared to those at the baseline was significant by the 1st post-injection week and insignificant at the 12th post-injection week in the dextrose and LA groups, and insignificant at both intervals in the saline group. In all the three groups, the MMO showed statistically insignificant difference throughout the study intervals. The pain relieving as evident by decreasing VAS and increasing PPT values was significant in the dextrose and LA groups at the 1st postinjection week compared to saline group. At the 12th post-injection week, the saline group showed statistically higher MMO mean than that of LA group. |
