title: Effect of Oral Appliance for Snoring and Obstructive Sleep Apnea.
abstract: To analyze therapeutic and clinical efficacy of mandibular advancement device (MAD) on snoring and obstructive sleep apnea (OSA). Thirty patients with OSA were recruited on the basis ofpolysomnography with an Apnea and Hypopnea Index (AHI) greater than 5 but less than 30. Repeat polysomnography was performed in follow up with the appliance in place. MAD used in the study is Medical Dental Sleep Appliance (MDSA). It is a titratable appliance. With the appliance in position, the mandible was advanced to an extent that did not exceed 70% of maximum protrusion capacity; Vertical opening did not exceed on an average 3-4 mm beyond freeway space. Comparison of pre AHI scores (diagnostic PSG) with post AHI scores (PSG with OA in-situ) showed a decrease from Mean +/- SD 26.2367 +/- 6.53 to 13.7111 +/- 627. A highly significant (p < 0.001) improvement in AHI was observed. Pre and post ESS score showed a mean decrease from 14.2333 +/- 5.00 to 6.1481 +/- 2.46 MDSA is effective in reducing apnea hypopnea index scores and improving oxygen saturation level.
