OBJECTIVES:Sleep bruxism (SB) frequently is associated with other sleep disorders and pain concerns. Our study assesses the efficacy of a mandibular advancement appliance (MAA) for SB management in adolescents reporting snoring and headache (HA). METHODS:Sixteen adolescents (mean age, 14.9±0.5) reporting SB, HA (>1d/wk), or snoring underwent four ambulatory polysomnographies for baseline (BSL) and while wearing MAA during sleep. MAA was worn in three positions (free splints [FS], neutral position [NP], and advanced to 50% of maximum protrusion [A50]) for 1 week each in random order (FS-NP-A50 or NP-A50-FS; titration order, NP-A50). Reports of HA were assessed with pain questionnaires. RESULTS:Overall, sleep variables did not differ across the four nights. SB index decreased up to 60% with MAA in A50 (P=.004; analysis of variance). Snoring was measured as the percentage of sleep time spent snoring. The subgroup of snorers (n=8) showed significant improvement with MAA (-93%; P=.002). Initial HA intensity was reported at 42.7±5/100 mm, showing a decreasing trend with MAA (-21% to -51%; P=.07). CONCLUSION: Short-term use of an MAA appears to reduce SB, snoring, and reports of HA. However, interactions between SB, breathing during sleep, and HA as well as the long-term effectiveness and safety of MAA in adolescents need further investigation.
