This report focuses on the periodontal manifestations of HCS.<\/jats:p><jats:p><jats:bold>Methods:<\/jats:bold> A 22\u2010year\u2010old female presented with the characteristic clinical features of HCS, including short stature, small face, prominent epicanthal folds, thin lips, small mouth, and short hands. There were no abnormal biochemical, hematological, or hormonal data. Tests for bone mineral density were indicative of osteoporosis. Cephalometric analysis revealed hypoplasia of the midface and increased cranial base angle; the maxilla and the mandible were set posteriorly. The sella turcica was enlarged, elongated, and wide open with slender clinoids. Hair samples were examined by scanning electron microscopy, and tooth cementum and dentin were evaluated histologically.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> According to the periodontal evaluation, gingival inflammation was 12.5%, bleeding on probing score was 24%, probing depths averaged 4 to 6 mm, and clinical attachment loss averaged 3 to 6 mm. Class II furcations were found on three teeth. Almost all teeth exhibited pathological mobility of varying degrees. There was a generalized, horizontal bone loss of \u223c50%. Three teeth had to be extracted because of severe localized periodontal destruction. Histologic examination of the dentin and the cementum was normal.<\/jats:p><jats:p><jats:bold>Conclusions:<\/jats:bold> HCS periodontitis is associated with an unpredictable and uneven, rapid rate of periodontal destruction of unknown etiology. Further research is required to identify the role of the possible pathogenic factors involved.<\/jats:p>","DOI":"10.1902\/jop.2007.060385","type":"journal-article","created":{"date-parts":[[2007,8,31]],"date-time":"2007-08-31T07:46:35Z","timestamp":1188546395000},"page":"1831-1838","source":"Crossref","is-referenced-by-count":22,"title":["Periodontitis Associated With Hajdu\u2010Cheney Syndrome"],"prefix":"10.1002","volume":"78","author":[{"given":"Euterpe","family":"Bazopoulou\u2010Kyrkanidou","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Theofilos P.","family":"Vrahopoulos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"George","family":"Eliades","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Heleni","family":"Vastardis","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Konstantinos","family":"Tosios","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ioannis A.","family":"Vrotsos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2007,9]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1259\/0007-1285-21-241-42"},{"key":"e_1_2_7_3_1","first-page":"595","article-title":"Acro\u2010osteolysis","volume":"94","author":"Cheney WD","year":"1965","journal-title":"AJR Am J Roentgenol"},{"key":"e_1_2_7_4_1","first-page":"215","volume-title":"Birth Defects","author":"Dorst JP","year":"1969"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1259\/0007-1285-37-441-702"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9343(78)90851-3"},{"key":"e_1_2_7_7_1","article-title":"Acroosteolysis with osteoporosis and changes in skull and mandible","author":"OMIM","journal-title":"Online Mendelian Inheritance in Man"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.1984.55.4.224"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1067\/moe.2003.151"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1097\/00006123-199608000-00037"},{"key":"e_1_2_7_11_1","first-page":"194","article-title":"Spontaneous regression of syringomyelia in Hajdu\u2010Cheney syndrome with severe platybasia.
