We hypothesised that the propensity to develop severe OSA could be minimised if the dental arches were enlarged in obese OSA people who are thought to have a large tongue. We therefore compared the size of the dental arches in obese and non\u2010obese OSA patients. Using a lateral cephalogram and study models, we compared the sizes of the tongue and dental arches in 23 obese and 23 non\u2010obese Japanese male OSA patients, who were matched for age, apnoea hypopnea index (AHI) and maxillomandibular size. The median age (years) and AHI (events per hour) for the obese and non\u2010obese groups were 36\u00b75 and 39\u00b70, and 13\u00b74 and 14\u00b73, respectively. The maxillomandibular size was matched with regard to SNA, SNB and lower face cage obtained from cephalometric measurements. The parameters that were measured for the study model included dental arch width, dental arch length, overjet and overbite. Tongue size (<jats:italic>P<\/jats:italic>\u2003&lt;\u20030\u00b705) and both upper (<jats:italic>P<\/jats:italic>\u2003&lt;\u20030\u00b701) and lower (<jats:italic>P<\/jats:italic>\u2003&lt;\u20030\u00b705) dental arch widths were significantly larger in obese than in non\u2010obese OSA patients, and there was no difference in the severity of OSA between the two groups. These findings suggest that the tongue was larger and dental arches were enlarged in obese patients compared with non\u2010obese patients under the same disease severity. Wider dental arches in obese OSA patients may help to offset the impact of the enlarged tongue on upper airway patency.<\/jats:p>","DOI":"10.1111\/j.1365-2842.2011.02243.x","type":"journal-article","created":{"date-parts":[[2012,1,6]],"date-time":"2012-01-06T16:36:22Z","timestamp":1325867782000},"page":"111-117","source":"Crossref","is-referenced-by-count":9,"title":["Difference in dental arch size between obese and non\u2010obese patients with obstructive sleep apnoea"],"prefix":"10.1111","volume":"39","author":[{"given":"K.","family":"MAEDA","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.","family":"TSUIKI","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.","family":"ISONO","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K.","family":"NAMBA","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"KOBAYASHI","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Y.","family":"INOUE","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2011,8,20]]},"reference":[{"key":"e_1_2_7_2_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199304293281704"},{"key":"e_1_2_7_3_2","doi-asserted-by":"publisher","DOI":"10.1093\/sleep\/22.5.667"},{"key":"e_1_2_7_4_2","doi-asserted-by":"publisher","DOI":"10.1097\/ALN.0b013e318173f103"},{"key":"e_1_2_7_5_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1479-8425.2004.00143.x"},{"key":"e_1_2_7_6_2","first-page":"953","article-title":"Orthodontic expansion and adenotonsillectomy in the treatment of obstructive sleep apnea in prepubertal children","volume":"31","author":"Guilleminault C","year":"2008","journal-title":"Sleep"},{"key":"e_1_2_7_7_2","doi-asserted-by":"publisher","DOI":"10.1097\/MLG.0b013e318068b566"},{"key":"e_1_2_7_8_2","doi-asserted-by":"publisher","DOI":"10.1378\/chest.09-2251"},{"key":"e_1_2_7_9_2","volume-title":"The Asia\u2010Pacific Perspective: Redefining Obesity and its Treatment","author":"World Health Organization (WHO), International Association for the Study of Obesity (IASO), International Obesity Task Force (IOTF)","year":"2000"},{"key":"e_1_2_7_10_2","doi-asserted-by":"publisher","DOI":"10.1253\/circj.66.987"},{"key":"e_1_2_7_11_2","first-page":"36","article-title":"A study of the tooth material in Japanese adults of normal occlusion, its relationship to coronal and basal arches [in Japanese]","volume":"16","author":"Ohtsubo J","year":"1957","journal-title":"J Jpn Orthod Soc"},{"key":"e_1_2_7_12_2","first-page":"362","article-title":"An adult case of skeletal open bite with a severely narrowed maxillary dental arch","volume":"72","author":"Takeuchi M","year":"2002","journal-title":"Angle Orthod"},{"key":"e_1_2_7_13_2","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-127-8_Part_1-199710150-00001"},{"key":"e_1_2_7_14_2","doi-asserted-by":"publisher","DOI":"10.1093\/ejo\/23.6.703"},{"key":"e_1_2_7_15_2","first-page":"648","article-title":"Maxillary morphology in obstructive sleep apnea: a cephalometric and model study","volume":"74","author":"Johal A","year":"2004","journal-title":"Angle Orthod"},{"key":"e_1_2_7_16_2","unstructured":"Japanese Ministry of Health Labour and Welfare.Survey of Dental Diseases;2005.
