Introduction: Obstructive Sleep Apnoea (OSA) is a sleep condition where the upper airway becomes partially or entirely blocked while you’re sleeping. As a result, sleep arousals and arterial oxygen saturation are reduced. According to the epidemiological survey, OSA is relatively common among people. Hence, there is need to analyse emotional stress in patients suffering from OSA. Need of the study: OSA and emotional stress are interconnected hence, a diagnosis of OSA is necessary to determine the patient’s level of emotional stress. Aim: The research protocol is planned determine stress level among patients suffering from moderate OSA and to compare the effect of gender on stress among such patients. Materials and Methods: A cross-sectional study will be conducted in expected time period of 6 months from May 2022 to October 2022 at Respiratory ward of Datta Meghe Institute of Medical Sciences, Maharashtra, india. This study design is planned to assess Emotional Stress among patients suffering from moderate OSA with sample size of 20 subjects (10 male,10 female) without any other demographic criteria consideration and recorded on Polysomnography (PSG). Patient was charged for PSG. An overnight PSG will be performed in Department of sleep medicine in chosen study institute. An online questionnaire will be used to gather and analyse information. The questionnaire will be consisting 14 statements. Study participants will be evaluated for stress level with previously survey validated questionnaire, Perceived Stress Scale (PSS) questionnaire given by American Sociological Association (ASA) to assess the stress level. Participants will be asked to rate stress according to a PSS score. Statistical analysis will be done using descriptive analysis.

Obstructive sleep apnea is caused by obstruction of the upper airway during the sleep This illness is characterised by a wide range of symptoms and associated comorbidities. OSA is a complex illness that necessitates a comprehensive approach to diagnosis and treatment. The craniofacial structure, as well as the soft tissues and muscles that surround it, all contribute to OSA.Obstructive sleep apnea affects 936 million individuals around the world. After China, India comes second with 81 million OSA patients. Continuous positive airflow (CPAP) as an interventional option and Oral Appliances as a non-interventional alternative have both been mentioned in the literature as therapy options for OSA. The clinical findings associated with OSA should be noted by the dentist during the initial session so that an early diagnosis, proper treatment planning, and the avoidance of long-term consequences can be accomplished. Dentists are crucial in diagnosis, treatment, and screening of OSA patients. Oral appliances for mandibular advancement and tongue stabilisation have been shown to be successful in treating OSA. The clinical studies, and current clinical practice suggest utilising oral appliances to treat OSA when patients cannot tolerate CPAP. Dental appliance therapy is a non-invasive treatment for obstructive sleep apnea syndrome that involves the use of a variety of dental appliances. This review provides an update on the most recent trends in Oral Appliances as a therapeutic option for managing OSA.
