“…Another limitation was the number of teeth present in the mouth. The literature shows that people with Down syndrome have a delay in the eruption period of the teeth, both permanent and primary. Thus, when evaluating the indices of decayed, missing, and filled permanent teeth (DMFT) and primary teeth (dmft), an adjustment to the number of teeth in the mouth should be done.…”

“…(1991)[ 8 ] found that among children with Down syndrome, 84% were caries-free. Orner's study (1975)[ 22 ] of the dental caries experience on Down syndrome contrasted with that of their unaffected siblings and showed that Down syndrome individuals had a caries experience less than one-third that of their siblings. This significant decrease in DMT and dmft in the present study could be attributed to increase in salivary electrolyte levels in the study group.…”

Aim:The aim of this study was to relate the salivary electrolyte levels with dental caries in children with Down syndrome and to compare salivary electrolyte levels and dental caries of these children with their siblings.Materials and Methods:Study population consisted of 30 Down syndrome children (study group) and their 30 healthy siblings (control group). Caries status was determined by dental caries indices in deciduous and permanent dentitions. Un-stimulated saliva from both groups was collected for salivary electrolyte examination.Results:In the study group, mean caries experience in primary dentition was 1.00 ± 0.79 and in the control group it was 2.33 ± 1.42, the difference being statistically significant. Mean caries experience in the permanent dentition of the study group (0. 97 ± 0.76) was significantly lower than the control group (2.47 ± 1.25). Salivary electrolyte levels in the study group were significantly higher than the control group.Conclusion:There was a significant decrease in dental caries in primary as well as permanent dentition of Down syndrome patients with increase in their salivary electrolyte levels.

Two hundred and forty pat.ents with Down syndrome trorr Santiago, Chile, were examined to determine the eruption time and sequence of their permanent dentition ir comparison with the oattern shown by normal Chilean population. Boys with Down syndrome show signricant delay in both maxillary and mandibular teeth eruption time. Among maxil.ary teeth, emotion was shown to be delayed in first right molar to 85.35 ± 20.03 months, in first eft molar to 87. 41 -22.37 In trie rnancible, right second molar and first premolar eruption time delays were documented to 163.30 ± 59.31 and 131.07 ± 21.94 months anc also for richt and left 'atera' incisors to 102.27 + 52.86 and 112.87 ± 73.46 months respectively. The sequence of upoer and lower denta' eruption of boys with Down syndrome shows great asyncrony wnich affects twenty teeth (71.4%) as compared with the normal population. In girls with Down syndrome this asynchronic sequence affects only 15 teeth (53.6%). One of the main differences between Down syndrome and normal individuals is due to the greater variance observed in the Down sample. (Key words: Down syndrome, teeth eruption, permanent dentition.)Los tiempos de la erupcion dentaria en el hombre varian normalmente tanto en la denticion temporal como en la definitiva. A pesar de ello la secuencia de erupcion es similar en todas las razas. En el control de la erupcion estarian implicados factores geneticos, ambientales y sistcmicos. que tendrian relacion con la presencia o ausencia de morfogenos que intervienen en los procesos de induccion primaria y secundaria de la odontoge'nesis y, por lo tanto, en la erupcion dentaria 1 . El retraso de esta ultima se ha asociado con desordenes sistemicos y se ha observado en los sindromes de Down y de Turner, Depaitamento de Biologia Celular y Genetica, Facult ad de Medicina, Division Ciencias Medicas Norte, Universidad de Chile. Departamento de Morfologia Experimental, Facultad de Medicina, Division Ciencias Medicas Noitc, Universidad de Chile. displasia cleidocraneal, atrofia hemifacial y mucopolisacaridosis, entre otros 2 . En el sindrome de Down se ha observado retardo de la erupcion en ambas denticiones, comparado con la poblacion normal 3 " 17 . En la denticion temporal se ha descrito retardo de la erupcion de los incisivos y caninos en ambos maxilares y la serie temporal se completa alrededor de los cuatro o cinco anos o despues. Los tiempos de erupcion de la denticion permanente son tambien irregulares. La extension del retardo, comparado con ninos normales, no se ha estudiado ampliamente 6 ' 8 . Algunas publicaciones han analizado las diferencias en la erupcion dentaria permanente al comparar ninos Down con sus hermanos normales 13 .El objetivo del presente estudio fue determinar el patron de erupcion de la denticion permanente en una muestra de ninos chilenos con sindrome de Down y compararlo con el patron de erupcion de la poblacion normal chilena. 89
