What is Bruxism
An open and ongoing debate for years
An oral activity (clenching and grinding)
that can occur in some person(s)
during WAKE and SLEEPhellip
Spectrum ndash not a continuum
- A usual oral motor activity in reaction to lifehellip
- Or an oral behavior- Or a disorder
(signs amp symptoms presence of risk factors
co morbidities etc) (small of population)

Sleep Bruxism definitionndash MEDICAL amp DENTAL
From parasomnia in medicine and parafunction in
dentistry
(Int Class Sleep Disorders 1 Am Acad Sleep Med)
- MEDICAL ICSD 2 and 3 (2014)
SLEEP Movement Disorder
- DENTAL Revisited (Lobbezoo et al J of O R 2013 and ICSD 3)
Repetitive jaw-muscle activity characterized by
clenching or grinding of the teeth andor by bracing
or thrusting of the mandible
Two distinct circadian manifestations sleep (indicated as sleep bruxism)
or wakefulness (indicated as awake bruxism)
POLYGRAPHY A sleep bruxism episode
with a cessation of breathing

1 A recent history of tooth grinding sounds occurring at least 3-5 nights per week over 6 months (if sleep alone)
+ in less than 50 of AWARE cases with sleep lab PSG
2 Presence of tooth wear
it is a YES or NO
- NOT for current or severity assessments
AND no difference in EMG measures

Sleep arousal

Suspect co-morbidity if
- Headache in morning ndash transient one
- If snoring and or mouth breathing
- Retrognathia large tonsil and tongue
- Fatigue sleepiness and INSOMNIA
- Rule out presence of RBDtapping GERD etc

SUMMARY SB (modified from Mayer Heinzer and Lavigne CHEST 2016)
Clinical INDICATORS- Tooth Grinding Sounds(current)
- Awareness of Clenching
- Tooth Wear (not reliable for current SB)
Sleep Recording
PSG (at least one Masseter muscle)
- Mild frequency of SB (2-4 RMMA episodehr)
Or
- Moderate to high frequency of RMMA (4 or + RMMA episodehr)
Presence of Sleep
Disordered Breathing
ENT andor Orthodontic
+ PSG (Md home)
Mandibular Advancement Appliance
(0 to 70 titration)
Or CPAP
With or without medication (see above)
Absence of
Sleep Disorder
Breathing
(SDB)
- Cognitive Behavioral Treatment (modest level of evidence)
- Occlusal Splint (no if SDB)
- Biofeedback sleep positional devices
- Medication clonazepam clonidine botulinum toxin (short term low dose amp medical supervision)

Clinical INDICATORS- Tooth Grinding Sounds(current)
- Awareness of Clenching
- Tooth Wear (not reliable for current SB)
Sleep Recording
PSG (at least one Masseter muscle)
- Mild frequency of SB (2-4 RMMA episodehr)
Or
- Moderate to high frequency of RMMA (4 or + RMMA episodehr)
Presence of Sleep
Disordered Breathing
ENT andor Orthodontic
+ PSG (Md home)
Mandibular Advancement Appliance
(0 to 70 titration)
Or CPAP
With or without medication (see above)
Absence of
Sleep Disorder

Clinical INDICATORS- Tooth Grinding Sounds(current)
- Awareness of Clenching
- Tooth Wear (not reliable for current SB)

- Mild frequency of SB (2-4 RMMA episodehr)
Or
- Moderate to high frequency of RMMA (4 or + RMMA episodehr)

SUMMARY SB (modified from Mayer Heinzer and Lavigne CHEST 2016)
Clinical INDICATORS- Tooth Grinding Sounds(current)
- Awareness of Clenching
- Tooth Wear (not reliable for current SB)
Sleep Recording
PSG (at least one Masseter muscle)
- Mild frequency of SB (2-4 RMMA episodehr)
Or
- Moderate to high frequency of RMMA (4 or + RMMA episodehr)
Presence of Sleep
Disordered Breathing
ENT andor Orthodontic
+ PSG (Md home)
Mandibular Advancement Appliance
(0 to 70 titration)
Or CPAP
With or without medication (see above)
Absence of
Sleep Disorder

(SDB)
- Cognitive Behavioral Treatment (modest level of evidence)
- Occlusal Splint (no if SDB)

SUMMARY SB (modified from Mayer Heinzer and Lavigne CHEST 2016)
Clinical INDICATORS- Tooth Grinding Sounds(current)
- Awareness of Clenching
- Tooth Wear (not reliable for current SB)
Sleep Recording
PSG (at least one Masseter muscle)
- Mild frequency of SB (2-4 RMMA episodehr)
Or
- Moderate to high frequency of RMMA (4 or + RMMA episodehr)
Presence of Sleep
Disordered Breathing
ENT andor Orthodontic
+ PSG (Md home)
Mandibular Advancement Appliance
(0 to 70 titration)
Or CPAP
With or without medication (see above)
Absence of
Sleep Disorder
Breathing
(SDB)
- Cognitive Behavioral Treatment (modest level of evidence)
- Occlusal Splint (no if SDB)
- Biofeedback sleep positional devices
- Medication clonazepam clonidine botulinum toxin (short term low dose amp medical supervision)
