The frequency of occurrence of abnormal frenal attachment of lips and enamel defects in Turner syndrome

Abstract

The results of the present study have shown, that abnormal attachment of lips and enamel defects were more frequent in Turner syndrome patients than in the control group. Enamel defects were correlated with the karyotypes of Turner syndrome and abnormal attachment of lips was not correlated with the karyotypes of Turner syndrome.

Supernumerary teeth in a patient with Turner syndrome: An unusual finding

“…Morphological changes in the dental crown have been previously described and are characterized by differences in mesiodistal and vestibulolingual width when compared with healthy individuals . Enamel hypoplasia has been described in TS patients, which was also found in the present case, such as talon cusp, enamel opacities and enamel hypoplasia …”

“…The oral features in individuals with TS, as described in the literature, are high‐arched palate, malocclusions, early dental development and premature eruption of permanent teeth, alterations in tooth shape and size, enamel hypoplasia, abnormalities in intercuspal distance, and abnormal root morphology . Here, we describe supernumerary teeth that have not been previously reported in patients with Turner syndrome.…”

“…Although the exact cause of Turner syndrome is unknown, the absence of all (45X monosomy) or part (deletions of the short and long arms) of a normal second sex chromosome, aberrations of X‐chromosome (eg, isochromosomes) and various mosaicisms appear to occur as a result of a random error during formation of either ovules or sperm cells . Additional genes can be involved in the pathogenesis, such as haploinsufficiency of SHOX genes, which explains the reduction in final height, changes in bone morphology, sensorineural deafness, and other features…”

Dentofacial Findings in Turner Sydrome

“…18,26,44,45,49,50 TS'li hastalarda mine hipoplazileri ve defektlerine daha sıklıkla rastlanmaktadır. 40 67 Günümüze kadar bir çok araştırmacının ilgisini çeken bu sendromun teşhis ve tedavisi yanında, kraniyofasial ve dental bulgularında da hala bir çok bilinmeyen vardır. .…”

Enamel defects and salivary methylmalonate in methylmalonic acidemia

“…Enamel defects have been associated with pediatric systemic illnesses during the critical period of enamel formation (Pindborg, 1982; Bhat and Nelson, 1989; Russell et al , 1996; Lucas and Roberts, 2005; Kusiak et al , 2007). Enamel anomalies have also been described in patients with specific metabolic disorders, such as phenylketonuria, an amino acid disorder (Myers et al , 1968; Lucas et al , 2001), and in those with mucopolysaccharidoses, a group of lysosomal storage diseases (Rølling et al , 1999; Barker and Welbury, 2000; Guven et al , 2008).…”
