Purpose
The purpose of this study is to evaluate the effect of Botulinum toxin type A(Meditoxin®) on bruxism using polysomnography and determine which site is most appropriate for injection to obtain maximal effects.

| Official Title: | Effects of Botulinum Toxin Type A(Meditoxin®) on Sleep Bruxism by Different Injection Sites Evaluated by Polysomnography |
- The change of bruxism events [ Time Frame: At 4 weeks after Botulinum toxin type A injection ] [ Designated as safety issue: No ]
Before and after injection, we compared the change of bruxism event in polysomnography by sleep laboratory criteria.
<Sleep laboratory criteria>
- Mean SB EMG potential : >10% or 20% of the maximal clench while awake (masseter muscles)
In M group, Botulinum toxin was injected into masseter muscle. In TM group, Botulinum toxin was injected into masseter muscle and temporal muscle.
- The change of masticatory force(%) [ Time Frame: At 4 weeks after Botulinum toxin type A injection ] [ Designated as safety issue: No ]We evaluated the change of subjective masticatory force before and after the injection. We asked the subject that "when the masticatory force before injection is represented 100%, what the masticatory force after injection?"
- The change of Pain [ Time Frame: At 4 weeks after Botulinum toxin type A injection ] [ Designated as safety issue: No ]We asked the subject about change of pain if the subject has pain on masseter muscle due to myogeneous problem. Pain score was chosen from a scale of zero to 10, where zero represented 'no pain' and 10 represented 'the worst pain they had ever experienced' (Numerical rating scale, NRS)
- Sleep-related movement disorders [ Time Frame: At 4 weeks after Botulinum toxin type A injection ] [ Designated as safety issue: No ]The percentage of subjects who have sleep-related movement disorders(ex, Restless Legs Syndrome, Periodic Limb Movement Disorder, Sleep Related Leg Cramps, Sleep Related Rhythmic Movement Disorder Sleep Related Movement Disorder, Unspecified)except sleep related bruxism
- Sleep-related breathing disorders [ Time Frame: At 4 weeks after Botulinum toxin type A injection ] [ Designated as safety issue: No ]The percentage of subjects who have sleep-related breathing disorders(ex, Obstructive Sleep apnoea, Sleep Related Hypoventilation/Hypoxaemic syndromes, sleep Related Non-obstructive Alveolar Hypoventilation(idiopathic), Sleep apnoea/Sleep Related Breathing Disorder, Unspecified and etc.)

Active Comparator: M group
A total of 25U of botulinum toxin type A was injected into each side masseter muscle in this arm.
|
Drug: Botulinum toxin type A (Meditoxin®)
In this study, the botulinum toxin type A (Meditoxin®)was supplied as a freeze-dried powder of 200U, and was reconstituted with 4ml of sterile saline to a concentration of 5U/0.1ml. After pre-injection polysomnography, botulinum toxin type A was injected into each side bilaterally using a 1ml-syringe with a 29-gauge, and a 1/2-inch needle. The "M group" had an injection in masseter muscle. The "MT group" had an injection in masseter and temporal muscle. A total of 25U of botulinum toxin type A was injected into each site. After 4 weeks, the subjects had a post-injection polysomnography. Other Name: Meditoxin®(PacificPharm corporation, Korea)

Detailed Description:
Bruxism is an oral habit consisting of involuntary non-functional gnashing, clenching, grinding of teeth and is a very common condition in the general population. Various treatment modalities such as occlusal splints, pharmacologic agent and cognitive-behavioral therapy have been investigated for the management of bruxism, but none is reported to be fully effective. Recently locally injected botulinum toxin has been used in various movement disorders, but its usefulness and objective effects on nocturnal bruxism have not been evaluated using objective measures such as polysomnography. Moreover, there is no systematic study about which site is most appropriate for injection to obtain maximal effects.
The aim of this study is to evaluate the effect of botulinum toxin type A into masseter muscle or both masseter muscle and temporal muscle on nocturnal bruxism using polysomnography and the changes in the bruxism events on polysomnography.
