4. EPIDEMIOLOGY
Awake bruxism - 20% among the adults
Sleep bruxism –
14% to 18% in children,
8% to 10% in adults,
3% in older people.
It is difficult to find the actual incidence as

discovery as a TMD.
 More often psychological factors like :

 Aggressive, competitive or hyperactive personality
 Side effects of certain anti-depressants.

6. AETIOLOGY
 Gastric reflux or food allergies.

following the arousal.

7. PRODROMES
 Bruxism may be loud enough to wake
your partner up.
 Worn down, chipped or fractured teeth.
 Abfraction
 Increased tooth sensitivity.
 Jaw pain and hypertonicity
of masticatory muscles.

8.  Dull morning headaches, at severe cases leading to migraines.
 Pain behind eyes and bloodshot eyes.

PRODROMES

9. DENTAL ATTRITION

10. HYPERTONICITYJAW PAIN

11.  General health and dental checkups.
 Inspection of teeth, underlying bones, inner surface of cheeks.
 Unusual wear and tear of teeth.
 Checking for tenderness of jaw muscles.
 X-Rays of mouth and jaw.
 Sensitivity of teeth.
DIAGNOSIS

12. DIAGNOSIS
 Broken or missing teeth or misalignment.
 The Bruxcore Bruxism-Monitoring Device (BBMD)-counts
the number of abraded microdots on its surface and by
scoring the volumetric magnitude of abrasion.

13. MANAGEMENT

14. 1. STRESS RELIEF
 If stress is the underlying cause, professional counseling or
meditation will promotes serenity to your mind.
 In children bruxism occurs when they are unable to share
their anger or anxiety. A relaxed conversation with them would
suffice.

15. 2. BEHAVIOR THERAPY
 Once discovered with bruxism, one must practice a
proper mouth and jaw positioning .
 Concentrate on resting your tongue upward and with
your teeth apart and lips closed.

16. 3. DENTALAPPROACHES
 Mouth guards called SPLINTS are used to prevent
damage to teeth.
 Properties of Splints:
 A full arch made of acrylic resin.
 Flat plain orthosis.
 Can be maxillary or mandibular.
 Undulation dictated by the occlusal plane.

17. 4.BIOFEEDBACK
 Electrical sensors are applied to different parts of your
body.
 Physiological response to stress- grinding of teeth- are
evaluated and information is fed to your auditory and
visual cues.

18. TO END WITH…
• Bruxism is simply a habit of malocclusion leading to
severe complications.
• Hardships often prepare ordinary people for an
extraordinary destiny.
