Using micro computed tomography (micro-CT) as a reference standard, the purpose of this investigation was to evaluate the influences of bone mineral loss and radiographic contrast in digital periapical (PA) film and cone-beam computed tomography (CBCT). Seven dog and human mandibles were sectioned, followed by modification via cortical bone drilling to create 248 lesions and/or trabecular bone acid demineralization to create 96 coronal slice pairs. Pretreatment and post-treatment radiographs (PA, CBCT, and/or micro-CT) were taken for lesion rating/perception in addition to two-dimensional (area) and three-dimensional (volumetric) measurements of 50 drilling lesions and 20 coronal slice pairs. 4-7% bone mineral loss …
Cpap-Mad Combination Therapy For Cpap Intolerant Patients With Moderate To Severe Osa, Jacob Stadiem
Cpap-Mad Combination Therapy For Cpap Intolerant Patients With Moderate To Severe Osa, Jacob Stadiem
Theses & Dissertations
The treatment of obstructive sleep apnea (OSA) allows for a multidisciplinary approach between dentistry and medicine. Continuous positive airway pressure (CPAP) is the gold standard for OSA treatment, but the non-adherence rates are high. The mandibular advancement device (MAD) has a higher acceptance rate than the CPAP, however the efficacy is much lower in cases of moderate to severe OSA. This thesis attempted to evaluate if there was a change in compliance when a MAD was added as a combination therapy to moderate to severe OSA subjects that were currently non-compliant with their CPAP. In addition, the change in air …
