The study also aims to understand whether this device can improve sleep quality and quality of life.\n\nThe main questions the study aims to answer are:\n\n* Does using a mandibular advancement device reduce the number and intensity of nighttime reflux episodes?\n* Does the device improve sleep and daily well-being in people with sleep apnea and reflux?\n\nResearchers will compare two types of oral appliances:\n\n* A mandibular advancement device, which moves the lower jaw forward during sleep\n* A lower jaw oral device without advancement, which also aims to help people with sleep apnea but does not reposition the jaw\n\nParticipants will:\n\nWear the assigned oral device every night for 6 months Visit the clinic for check-ups and adjustments Complete short questionnaires about reflux symptoms, sleep quality, swallowing, diet, and quality of life Have saliva pH measured and X-rays taken before and after using the device This study hopes to find out whether oral devices can be a good option for people who do not tolerate CPAP therapy.",[28],"Gastroesophageal Reflux Disease",[30,31],"Gastroesophageal reflux","Sleep Apnea, Obstructive","NOT_YET_RECRUITING","2025-07-02",{"date":35,"type":36},"2025-07-08","ACTUAL",{"date":38,"type":22},"2025-08-01",{"date":40,"type":22},"2026-12-01",{"name":42,"class":43},"Tuiuti University of Paraná","OTHER",""]
