Turner syndrome isochromosome karyotype correlates with decreased dental crown width

Abstract: The aim of this project was to study possible influences of Turner syndrome (TS) karyotype and the number of X chromosomes with intact short arm (p-arm) on dental crown width. Primary and permanent mesio-distal crown width was measured on plaster casts from 112 TS females. The influence on crown width of four karyotypes: 1. monosomy (45,X), 2. mosaic (45,X/46,XX), 3. isochromosome, and 4. other, and the number of intact X chromosomal p-arms were investigated. In comparisons between karyotypes, statistically si… Show more

“…Turner patients, especially 45,X females, have significantly retarded skeletal maturity, while dental maturity and tooth eruption are advanced [5][6][7]. There is also a marked reduction in the mesiodistal and labiolingual dimensions of the permanent and deciduous tooth crowns [5,[8][9][10][11][12][13][14] and there have also been reports of decreased crown heights in the permanent incisors and canines in this syndrome [15]. Varrela et al [11] found that the tooth crowns of 45,X and 45,X/46,XX females (a female with one X cell line and one normal XX line) were almost the same in the mesiodistal direction, while the 45,X/46,XX females had larger crowns in the labiolingual direction.…”

“…26,46,47,49,50,53 Ayrıca süt dişi kuron boyutlarında da sapma olduğu bildirilmiştir. 18,51,55 Bu hastalarda dişlerin kuron çapının küçülmesi bir çok etkene bağlı olmasına rağmen , mine kalınlığındaki azalma birinci derecede sorumlu tutulmuştur. 18,26,44,45,49,50 TS'li hastalarda mine hipoplazileri ve defektlerine daha sıklıkla rastlanmaktadır.…”

“…28,32 Turner sendromunda daimi diş sürmesinde gecikme, küçük dişler, basit kron morfolojileri, ince mine, kı-sa kökler ve idiopatik kök rezorbsiyonları gibi dental anomalilere rastlanmaktadır. 33,34 Rizell ve ark.nın 35 Turner sendromunun karyotiplerinin kron genişliği üzerin-deki etkilerini araştırdığı çalışmada, kron boyutunun X kromozumuyla ilişkili olduğu ve izokromozom karyotipin en düşük kron boyutu gösterdiği tespit edilmiştir.…”
