AUSTRO MARTINEZ, M.D.; OSTOS GARRIDO, M.J.; GARCIA BALLESTA, C.  and  PEREZ LAJARIN, L.. Analysis of symmetry mesiodistal size teeth in mixed and permanent dentition in the same sample: A longitudinal study. Av Odontoestomatol [online]. 2004, vol.20, n.6, pp.305-312. ISSN 2340-3152.

In the present work is analysed the mesiodistal diameters of the temporal and permanent teeth of the same sampie to calculate the symmetry. The first sample was 267 children, 90 girls (34%) and 177 (66%) boys from Oriental Andalusia, aged between 8 and 10 years old. After four years, we analysed the same children with permanent teething and we obtained just a sample of 171, 69 girls (40%) and 102 (60%) boys, with an average age of 12 years and a range from 11 to 13 years, using as criteria selection not having morphological alteration, teeth loss, important congestions, between other elements. The teething dimension was measured as the maximum distance between the mesiodistal contact points of the crown, using a sharp-end gauge, with a 0,1 mm precision. All the measurements were made by the same viewer, directly to the mouth. For the statistic analysis was used the t Student test, with a level of statistic signification of p< 0,05. The main results include the symmetry of the mesiodistal size both in a mixed dentition and a permanent dentition, of the same sample.

Keywords : Mesiodistal size teeth; symmetry.
