Given the strong association between OSA and cardiovascular morbidity and mortality, it is important to know whether oral appliance treatment has a similar beneficial cardiovascular effect compared with CPAP. To date, the only cardiovascular outcome to be assessed is blood pressure, and two randomized placebo-controlled studies, using intention-to-treat analyses, have reported a modest reduction in 24-hour blood pressure (2-4 mmHg) with oral appliance treatment over period of one month (29) and three months (26). One study compared an oral appliance to CPAP, and found a small reduction in nocturnal diastolic blood pressure with oral appliance only (26). More recently, an uncontrolled study involving 161 subjects reported reductions in office blood pressure, with the change being significantly correlated to baseline blood pressure (30). These early studies suggest a beneficial effect of oral appliances, and additional work is required to further examine blood pressure and other cardiovascular outcomes.
