Description:	Oral health practitioners play a fundamental role in airway screening. We deal with the airway on a daily basis and are exposed to more than half of the anatomical factors that can lead to chronic mouth breathing and sleep disordered breathing. Early detection of chronic mouth breathing is important, especially in children and young adults. Chronic mouth breathing secondary to nasal obstruction leads to breathing disorders that affects sleep. Sleep disordered breathing leads to neurocognitive, mood and behavioural problems as well systemic health problems. Obstructive sleep apnea (OSA) and upper airway resistance syndrome (UARS) are two types of airway disorders observed during sleep that leads to sleep disorders. Our study focuses on identifying the prevalence of undiagnosed mouth breathers among young healthy adults. We aimed to come up with clinical guideline to help airway screening in the individuals who may be undiagnosed and silently risking themselves to developing systemic health morbidities related to mouth breathing and sleep disordered breathing. Our study included 156 subjects with a mean age of 23 years that underwent two phases of clinical assessment. The first phase included questionnaires and clinical examinations while the second phase involved nasal endoscopy to look for nasal pathology. Our results showed that the prevalence of undiagnosed mouth breathers was high at 90.4%. We found that there was a mixed pattern of dental morphometry changes from the normal breather and significant association between allergy, tongue scalloping and snoring with the presence of mouth breathing. Analysing specific components in the Sino Nasal Outcome Test-22 and Epworth Sleep Scale related to sleep rather than just looking at the total score was highly sensitive in picking up the presence of an undetected sleep disorder. We concluded that in the undiagnosed mouth breather’s upper airway resistance syndrome was factor contributing to a sleep related disorder. We present our clinical airway screening guideline that can be used in a dental setting to improve oral health practitioner’s role in screening for obstructive sleep apnea and upper airway resistance,Ijazah Doktor Pergigian Klinikal (Bedah Mulut Dan Maksilofasial)
