Dental Sleep Medicine is a branch of Dentistry that deals with the DIAGNOSIS & TREATMENT of sleep-disorders such as Snoring, Obstructive Sleep Apnoea (OSA), and Sleep Bruxism
BRUXISM & TEETH CLENCHING
Bruxism is excessive teeth grinding or jaw clenching. Bruxism is a common behavior; reports of prevalence range to about 31% in the general population. Several symptoms are commonly associated with bruxism, including hypersensitive teeth, aching jaw muscles, headaches, tooth wear, and damage to dental restorations (e.g. crowns and fillings). If nothing is done, after a while many teeth start wearing down until the whole tooth is gone.
Recent studies have shown that Obstructive Sleep Apnoea (OSA) as one the leading causes of Bruxism. Thus treating OSA helps reduce sleep bruxism and improving oral heath
The temporomandibular joint (TMJ) is a hinge that connects your jaw to the skull, which lets you move your jaw up and down and side to side, so you can talk, chew, and yawn.
Sleep Bruxism, Sleep Apnoea and Teeth Clenching are some of the common issues that lead to pain in the TMJ.
Sleep Apnoea results in blood oxygen levels to drop in sleep, and also results in mouth breathing. Mouth breathing drys up the saliva from the mouth, result in bacterial growth in the teeth during sleep!
Based on the outcome of the sleep study, the patient can be treated either using a Mandibular Advancement Appliance or CPAP Machine. CPAP machines are normally recommended for patient with severe OSA. For Mild to Moderate cases, the dental appliance can be recommended.
Scientic studies over the years have shown that Mandibular Appliances can help improve OSA to a great extent.
Also, being more comfortable and affordable than CPAP machines, the acceptance and adherance of Mandibular Appliances are far greated than CPAP machines,
HOW A PATIENT SUFFERING FROM SLEEP APNOEA & DAYTIME SLEEPINESS GOT RELIEF USING SNOOZFIT ATOM
For mild cases of Teeth Bruxism, a single plate night guard could sufffice.
However for more severe cases, and those cases that have comorbidities with OSA, a mandibular appliance is recommended.
The mandibular applaince reduces OSA by opening up the airways and also holds the lower jaw in place, thereby reducing Sleep Bruxism and associated side effects.
Studies has shown than the intentensity of Sleep Bruxism can be signficantly reduced using Mandibular Appliances. ( Reduction of sleep bruxism using a mandibular advancement device: An experimental controlled study Article in The International journal of prosthodontics · November 2006)
Good regular sleep is fundamental not only for our mental and physical wellbeing, but also for our dental health.
Sleep deprivation can lead to dental health issues like bleeding gums, loose teeth, gum infections, teeth grinding, and if left to persist, it can even lead to tooth decay and tooth loss!
