SNORING

"Laugh and the world laughs with you
Snore and you sleep alone."

Snoring is partially obstructed breathing Some 76 million people in North America (U.S. and Canada) suffer from snoring. Snoring is frequently a person's most socially disruptive and annoying personal trait. Recent research reveals that continuing throughout life as a snorer or a sleep apneic no longer is unavoidable, but rather is a personal choice - a decision by a specific person not to do anything about it.

• 60% of males and 40% of females over the age of 60 snore. (Female snoring increases after menopause.)
• The loudness of snoring may reach as high as 90 db.
  (Worker’s compensation requires ear protection in the workplace at 90 db.)
• 98.5% of snorers exhibit some apneic tendencies.

Snoring can lead to sleep apnea because it can change tissue structure. In recent clinical studies, dentists and physicians have found that, in the majority of patients, a well-made, well-fitted dental appliance will effectively reduce or eliminate snoring.

Most sleep researchers agree that the position of the tongue during sleep is a substantial causative factor in both snoring and sleep apnea. As a person goes to sleep, especially while lying on his or her back, the muscles of the tongue and jaw relax and these structures move backward against the posterior wall of the throat. As the airway becomes partially blocked, snoring occurs . If it progresses to complete airway blockage, sleep apnea (multiple stoppages of breathing for 10 seconds or longer) occurs . The tongue is attached to the lower jaw. By moving the lower jaw forward with a nighttime dental appliance, the tongue is moved forward, the airway is opened up and stays opened, and snoring stops. The snoring stays stopped as long as the appliance is worn. Most severe snorers wear their appliances for the rest of their lives. The downside of the dental approach is that there is a two to three night adjustment period (as with any other item such as contact lenses) and possible sore teeth for a few nights if the snorer is a nighttime tooth grinder. Upon awakening, your bite may be different for approximately thirty minutes.

Upper Airway Resistance Syndrome (UARS)

The term “Upper Airway Resistance Syndrome” (UARS) is used to describe chronic daytime sleepiness that is often accompanied by snoring, brief yet frequent arousals, and only slightly abnormal breathing.
Unlike snoring and obstructive sleep apnea, UARS is often more prevalent among women than men.

Symptoms may include:

• Sleep-onset insomnia
• Headaches
• Gastroesophageal reflux
• Depression
• Bruxism (grinding of teeth),
• Rhinitis
• Hypothyroidism
•Asthma

People who suffer from UARS lack the typical findings of apnea, hypopnea and nighttime oxygen desaturation on polysomnography (diagnostic sleep studies). As a result, UARS is often not diagnosed by physicians. However, the arousals and sleep fragmentation related to an increased effort to breathe can be diagnosed by measurement of pressure changes in the esophagus.

Obstructive Sleep Apnea (OSA)

Virtually all people that have sleep apnea snore, but not all snorers have sleep apnea. Because sleep is repeatedly interrupted during the night you never get a full night's sleep, and day-time sleepiness is a second major indication. Other indications include falling asleep during the day, automobile accidents or accidents on the job due to tiredness or exhaustion, changes in personality, mental fatigue resulting in difficulty in thinking and concentrating, frequent nocturnal urination, and high blood pressure with the attendant increased risks of heart attack and stroke. Suspect you have sleep apnea if your spouse reports that your stoppage of breathing, gasps, choking, and your attempts to start breathing again "scare her to death."

Obstructive sleep apnea (OSA) is far more common than central sleep apnea . OSA occurs when air cannot flow into or out of the person’s nose or mouth, although efforts to breathe continue. In a given night, the number of involuntary breathing pauses – or “apneic events” – may be as high as 20 to 60 or more per hour. Snoring and choking between apneic events is common, although not everyone who snores has OSA. The frequent interruptions of deep, restorative sleep often lead to excessive daytime sleepiness and may be associated with early morning headache.

OSA occurs in all age groups and both sexes but is more common in men (it may be underdiagnosed in women). Early recognition and treatment is important because OSA may be associated with irregular heartbeat, high blood pressure, heart attack, and stroke.

• Once diagnosed, OSA is often managed through the use of a Continuous Positive Airway Pressure (CPAP) machine or dental appliances that reposition the lower jaw and the tongue.
Rates of OSA are 2x-4x higher after age of 50.
• Mild to moderate sleep apnea patients are the most likely not to be screened.
• Untreated sleep apnea can put you at increased risk of developing:

o Hypertension
o Heart disease
o Stroke
o Diabetes

Central Sleep Apnea

There are two main types of sleep apnea. “Central Sleep Apnea” appears to be related to a malfunction of the brain’s normal signal to breathe, therefore cannot be treated by dental sleep appliances. It is less common than “Obstructive sleep apnea” which may represent cessation of breathing due to mechanical blockage of the airway.
Prompt and proper diagnosis is an important first step to treating any and all forms of sleep apnea. Problems associated with untreated sleep apnea include hypertension, coronary artery disease, myocardial infarction, stroke, psychiatric problems, impotence, cognitive dysfunction, memory loss, and death.

Sleep Bruxism

Sleep Bruxism (SB) is the gnashing, clenching or grinding of the teeth during sleep. It is the third most prevalent sleep disorder, after sleep talking and primary snoring.
Tooth grinding or tooth-clenching during sleep may cause:

• Abnormal wear of the teeth.
• Sounds associated with bruxism (It's about as pleasant as fingernails on a chalkboard!).
• Jaw muscle discomfort.

Some people have episodes of SB that occur less than nightly with no evidence of dental injury or impairment of psychosocial functioning. Others experience nightly episodes with evidence of mild impairment of psychosocial functioning. Yet others have nightly episodes with evidence of dental injury, temporomandibular joint (jaw) disorders , or moderate or severe impairment of psychosocial functioning.

Excessive Daytime Sleepiness

Excessive Daytime Sleepiness (EDS) is a condition in which an individual feels very drowsy during the day and has an overwhelming urge to fall asleep, even after getting enough nighttime sleep. People with EDS frequently doze, nap, or fall asleep in situations where they need or want to be fully awake and alert. This can be particularly dangerous at times, such as when driving a car or operating other hazardous machinery.

EDS can interfere significantly with a person's ability to concentrate and perform daily tasks and routines. People with EDS often report feelings of low self-esteem, frustration, and anger about being misunderstood and regarded as unintelligent, lazy or uninterested in learning. They also report having difficulty with relationships -- in social situations, in the workplace, and within the family.

EDS is a sign of an underlying medical condition, typically a sleep disorder.
