The Genetics of Hypodontia

Abstract: A large body of family data was analyzed to explain the genetics of hypodontia. Two multiple threshold models that were developed for quasicontinuous traits were used. The data fit the polygenic model much better than they fit the single major gene model.

“…4 An early investigator 5 has shown that there is an antero-posterior gradient in relative crown size reduction and a posterioranterior gradient for tooth formation in people with missing third molar teeth. Relatives too may show dental effects other than hypodontia; In comparison with a control group, relatives of people with hypodontia demonstrated a reduc-1.…”

“…12 Se han reportado cifras de hipodoncia de laterales en la población normal del 2,2% y en pacientes con labio y paladar del 56,9%. 13,14 En un estudio realizado en Colombia, se buscó establecer el patrón de herencia de agenesias dentales en siete grupos familiares, se encontró que los dientes ausentes con mayor frecuencia fueron los laterales superiores (46,1%) seguido por los segundos premolares inferiores (7,69%). 15 Los resultados del presente estudio mostraron hipodoncia de premolares del 7% en pacientes con labio y paladar hendido.…”

“…El 35% de las madres presentó antecedente de fumadora y el 43% acostumbraba a tomar alcohol. Se encontró que las mujeres en embarazo que habían consumido alcohol tenían una probabilidad 1,5 veces de tener un hijo/a con labio y/o paladar hendido aunque este valor no fue estadísticamente significativo [OR 1,5 IC 95% 0,[13][14][15][16][17]66]. Conclusiones: al determinar la asociación entre el consumo de cigarrillo y alcohol como factor de riesgo en labio y paladar hendido, no se encontró una relación estadísticamente significativa, pero sí una relación positiva entre las variables mencionadas.…”

“…Lavelle (1977) remarks on the quasi-continuous nature of most dental measurements, and Suarez and Spence (1974) propose that a polygenic model best explains hypodontia. Tooth size reduction has been documented in patients with Down's syndrome (Geciauskas and Cohen, 1970;Barden, 1980).…”
