Bruxism "Bruxism is a repetitive jaw-muscle activity characterized by clenching or grinding of the teeth and/or by bracing or thrusting of the mandible. Bruxism has two distinct circadian manifestations: it can occur during sleep (indicated as sleep bruxism) or during wakefulness (indicated as awake bruxism)."All forms of bruxism entail forceful contact between the biting surfaces of the upper and lower teeth. In grinding and tapping this contact involves movement of the mandible and unpleasant sounds which can often awaken sleeping partners and even people asleep in adjacent rooms. Clenching (or clamping), on the other hand, involves inaudible, sustained, forceful tooth contact
Habitual offender Habitual offender A habitual offender, repeat offender or career criminal is a person convicted of a new crime who was previously convicted of a crime(s). Various state and jurisdictions may have laws targeting habitual offenders, and specifically providing for enhanced or exemplary punishments or other sanctions. They are designed to counter criminal recidivism by physical incapacitation via imprisonment. The nature, scope and type of habitual offender statutes vary, but generally they apply when a person has been convicted twice for various crimes. Some codes may differentiate between classes of crimes (for example, some codes only deal with violent crime) and
