The purpose of this study is to evaluate the effects of botulinum toxin type A (BoNT-A) for managing sleep bruxism (SB) in a randomized, placebo-controlled trial. Thirty SB subjects were randomly assigned into two groups evenly. The placebo group received saline injections into each masseter muscle, and the treatment group received BoNT-A injections into each masseter muscle. Audio–video–polysomnographic recordings in the sleep laboratory were made before, at four weeks after, and at 12 weeks af

The aim of the study was to propose a more efficient and safer botulinum toxin type A (BoNT-A) injection method for the masseter by comparing the conventional blind injection and a novel ultrasonography (US)-guided injection technique in a clinical trial. The 40 masseters from 20 healthy young Korean volunteers (10 males and 10 females with a mean age of 25.6 years) were included in this prospective clinical trial. The BoNT-A (24 U) was injected into the masseter of each volunteer using the conv

OBJECTIVE: To present a case that neuropathic pain following traumatic injury of the inferior alveolar nerve, which was relieved by the injection of BTX-A. DESIGN: Case report. SETTING: Tertiary care University hospital. SUBJECT: A 62-year-old female was referred by her general dentist to our clinic due to numbness and pain over the left side of her lower lip and chin region. INTERVENTION: Botulinum toxin type A injected into the middle of chin area subcutaneously. RESULTS: At 1 month after BTX-

OBJECTIVE: The aim of this study was to determine whether the ID Migraine questionnaire could be applied successfully to assess the migraine patients in TMJ and Orofacial Pain Clinic. BACKGROUND: As migraine pain represents a substantial personal and social burden worldwide, there has been a great deal of effort in developing a screening instrument for migraine. METHODS: Each subject completed a self-administered screening questionnaire consisting of nine items. Based on the International Headac

Unilateral BoNT-A injection appears to be an effective esthetic treatment for patients with muscle-induced facial asymmetry.

BACKGROUND: Botulinum toxin (BoNT) is widely used to treat masseter muscle hypertrophy. Changes in the muscle thickness have been found in many studies, but there has been no report on changes in the thickness from the skin surface to the masseter muscle. OBJECTIVES: We aimed to use ultrasonography to measure not only changes in the muscle thickness but also changes in subcutaneous thickness. METHODS: This study enrolled 20 volunteer patients: 10 were assigned to an experimental group (injected

Since the start of the 2019 coronavirus pandemic, interest in digital therapeutics (DTx) has increased. Temporomandibular disorder (TMD) fundamentally requires cognitive behavioral therapy (CBT), including physical self-regulation. An application that records TMD pain and parafunctional activities for CBT has recently been developed. However, evidence of the reduction of clinical symptoms in patients via repetitive software-driven CBT is lacking. The purpose of the present study was to evaluate

Botulinum toxin type-A (BTX-A) injection for treating chronic migraine (CM) has developed into a new technique covering distinct injection points in the head and neck regions. The postulated analgesic mechanism implies that the injection should be administered to sensory nerves rather than to muscles. This study aimed to determine the topographical site of the auriculotemporal nerve (ATN) and to propose the effective injection points for treating CM. ATNs were investigated on 36 sides of 25 Kore

The purpose of this study was to compare the efficacy of botulinum toxin (BoNT) in masseter muscle reduction depending on the amount of chin deviation. Exploring distinctive effects of BoNT relative to the characteristics of facial asymmetry will aid in planning and predicting treatment outcomes. Sixteen adult volunteers were classified into two groups according to the degree of menton deviation observed in posteroanterior cephalograms. Eight had a menton deviation of 3 mm or more and the other

Intractable chronic occipital neuralgia (ON) is an uncommon type of headache often experienced by patients in outpatient neurological clinics. Among patients unresponsive to oral neuralgia medications, needling or injections with several drugs were suggested alternatives for treating chronic ON. This study aimed to determine the effectiveness and safety of botulinum toxin type-A (BTX-A) injection treatments, where eight patients with unilateral chronic ON received BTX-A injections at the pain si

BACKGROUND: Trigeminal nerve injury following endodontic treatment, leading to unpleasant sensations or partial sensory loss in the face or oral mucosa, is uncommon but significant when it occurs. OBJECTIVE: This study analysed the pharmacological management of trigeminal nerve injuries (TNI) in a university-based hospital. METHODS: We conducted a retrospective analysis of 47 patients who visited the Department of Orofacial Pain and Oral Medicine at Yonsei University Dental Hospital, Seoul, Kore

These results imply that clinicians treating patients with orofacial pain should examine their sleep-wake patterns and sleep quality.
