Study summary

Patients with orofacial pain lasting at least 3 months. The patients will be randomly assigned to one of the two groups according to the treatment method: group I (intraoral injection) and group II (transcutaneous injection) where each patient injected Botox at each trigger point according to the treatment group by the same operator. Patients will be examined by a blinded investigator at pre- and post-injections at the following intervals: during diagnosis, 1 week, 4, and 6 weeks post-injection. The patients will be assessed using a pain score measured on a 10-point visual analog scale (VAS). The secondary outcome assessed will be measuring the quality of life in an Oral Health Impact Profile questionnaire (OHIP-14).

What researchers measure

Primary outcomes

  1. pain score

    The participated patients will be assessed using pain score measured on a 10-point visual analogue scale (VAS), the 0 indicating no pain and 10 indicating the worst pain ever.

    Time frame: 6 weeks post injection

Secondary outcomes

  1. (OHIP-14) scale

    OHIP-14 is used to measure patients' self-reported discomfort, disability, and functional limitation due to oral conditions with scores ranging from 0 to 56 (with 56 representing a subject answering ''very often'' to all 14 items

    Time frame: 6 weeks
