Abstract

VAILLARD JIMENEZ, Esther; HUITZIL MUNOZ, Enrique  and  CASTILLO DOMINGUEZ, Loida. Characteristics of Roots Canals of Deciduous Teeth. Int. J. Odontostomat. [online]. 2015, vol.9, n.1, pp.159-164. ISSN 0718-381X.  http://dx.doi.org/10.4067/S0718-381X2015000100024.

The aim of this study was to identify in roots canals of deciduous teeth anatomical variants in pulpar cavity. In a clinical, descriptive, cross sectional ex vivo study was analyzed a sample of 60 deciduous teeth of healthy Mexican children. Each tooth was conserved in distillated water and were transparency with a technic modified for deciduous teeth. Identifications of root canals was made twice by a lonely observant (k= 0.7947). Simple root teeth show 50% simple and lateral root canal, 25% secondary, 25% delta. Upper molars show 8% simple canal in each root. Lower molars 29%. Secondary root canals, parallel and recurrent were identified in 33% of cases. 100% of distal roots of lower molars have reticular canals. Root fusions are presents in 88% of lower molars. In conclusion, root canals anatomy of deciduous teeth is high complex.

Keywords : root canals; deciduous teeth; dental transparency.
