“…25 Patients with neurological disorders who are in a comatose state can also have severe bruxism. 24 The activation of phasic jaw activity may depend on the interaction between the motor, limbic, and autonomic systems, resulting in either disinhibition or facilitation of a central bruxism generator. 1 Cases have also been reported of total recovery from bruxism.…”

“…1 Although no central nervous system structures associated with teeth grinding have been identified, it has been speculated that, in some cases, bruxism may be a part of dystonia because both share similar pathophysiology. 24 Bruxism involves jaw clenching and grinding of the teeth, commonly causes myofascial pain, and is often resistant to treatment. 2 A higher prevalence rate of bruxism has been reported in cranial-cervical dystonia compared with healthy control.…”

Objective: The purpose of this case study is to present the findings of combining botulinum toxin type A (BoNT-A) and cervical spine manual therapy to address masseter muscle spasticity in a patient with Alzheimer-type dementia. Case Report: A 78-year-old woman with bilateral spasticity of the masseteric regions for 2 years was referred for physiotherapy. She had trismus and bruxism, and could neither close nor open her mouth normally; thus, she was unable to be fed orally in a normal manner. Intervention and Outcome: The patient underwent combined treatment with BoNT-A and cervical spine manual therapy. A medical physician (neurologist) performed the BoNT-A injections into 2 points at the center of the lower third of the masseter muscle. A physical therapist performed manual therapy interventions targeted at the cervical spine. Manual therapy started the day after the BoNT-A injection and continued for 5 sessions per week for a total period of 2 weeks. Clinical outcomes were measured including spasticity (Modified Ashworth Scale), functionality (Barthel Index), and jaw opening. Outcomes were conducted at baseline, 2 weeks after treatment, and at 2-month follow-up session after finishing the treatment. The patient improved in all of the outcomes at the end of treatment, and these Journal of Chiropractic Medicine (2012) 11, 280-285 results were maintained during the follow-up. After treatment, the patient was able to feed with minimal caregiver dependency because oral feeding was possible. Conclusion:The patient in this study responded positively to a combination of BoNT-A and manual therapy, resulting in decreased masseter muscles spasticity and improved trismus and bruxism.

“…If not controlled, wear could lead to poor masticatory function, with a concomitant reduction in quality of life and possible deterioration of systemic health. [16][17] Thus, rather than considering esthetic improvement as the main criterion for material selection, tooth conservation should be the primary goal of treatment planning.…”

The data obtained in this study can help practitioners with selection of the appropriate restorative materials to minimize further tooth and restoration wear, which is an important consideration during treatment planning. SUMMARYThis in vitro study compared the effects of a gold alloy (Degulor M), four dental ceramics (IPS Empress, IPS Empress 2, Duceram Plus, Duceram LFC) and a laboratory-processed composite (Targis) on the wear of human enamel. The amount of wear of the enamel (dental cusps) and restorative materials (disks) were tested in water at 37°C under standard load (20 N), with a chewing rate of 1.3 Hz and was determined after 150,000 and 300,000 cycles. Before the test, the average surface roughness of the restorative materials was analyzed using the Ra parameter. The results of this study indicate that Targis caused enamel wear similar to Degulor M and resulted in significantly less wear than all the ceramics tested. IPS Empress provoked the greatest amount of enamel wear and Degulor M caused less vertical dimension loss. Targis could be an appropriate alternative material to ceramic, because it is esthetic and produces opposing enamel wear comparable to gold alloy.

“…However, the previous studies have not investigated the effect of botulinum toxin on neck pain caused by bruxism, only jaw pain due to bruxism or neck pain due to cervical dystonias. [18][19][20][21]28 Because neck pain is commonly coexisting with craniofacial pain in TMD, this case report may be of interest. The following is a case report of a patient presenting with nocturnal bruxism with related neck pain and treated with BTX-A.…”

“…6 Myofascial pain is described as a muscle hyperactivity involving facial pain related to temporomandibular disorders (TMDs), a craniofaciocervical dysfunction not completely understood. 18,19 Usually, masseter and temporal muscle hyperactivity determines tension headaches and neck pain. 20,21 Therefore, it was hypothesized that the temporal and masseter muscles could be involved into the pathogenesis of bruxism; so BTX-A can be used to decrease the hyperactivity of these muscles for reducing this condition.…”

Objective: This case report describes a patient with nocturnal bruxism and related neck pain treated with botulinum toxin type A (BTX-A). Clinical Features: The patient was a 27-year-old man with nocturnal bruxism and difficulty in active mouth opening and chewing and neck pain at rest. His numeric pain score was 7 of 10. Surface electromyography of the temporalis and masseter muscles showed typical signs of hyperactivity, characterized by compound muscle action potential amplitude alterations. Intervention and Outcome: After clinical evaluation, he was treated with BTX-A to reduce masseter and temporalis muscle hyperactivity. After 3 days of treatment with BTX-A, with each masseter muscle injected with a dose of about 40 mouse units with a dilution of 1 mL and with temporal muscle bilaterally injected with 25 mouse units with the same dilution, a decrease in bruxism symptoms was reported. Neck pain also decreased after the first treatment (visual analog scale of 2/10) and then resolved completely. After 4 weeks, electromyography showed the reduction of muscle hyperactivity with a decrease in the amplitude of the motor action potential. The same reduction in signs and symptoms was still present at assessment 3 months posttreatment. Conclusion: These findings suggest that BTX-A may be a therapeutic option for the treatment of bruxism and related disorders.
