CUETO URBINA, Alfredo; AVILA RIVERA, Claudia  y  GONZALEZ RIOS, Jenniffer. Dentoalveolar Injuries Affecting Tooth Support Structures in Temporary and the Effects on Permanent Succesors. Int. J. Odontostomat. [online]. 2012, vol.6, n.3, pp.379-383. ISSN 0718-381X.

The purpose of this study was to determine the effects produced in the permanent teeth after trauma affecting the supporting structures of teeth. The sample is 53 children beneficiaries of the Reference Center Odontopediátrico Simon Bolivar, ages 1 to 7 years who suffered injury of the anterior dentoalveolar trauma during the period 2005-2007 that was classified according to Andreasen: subluxation, lateral luxation, intrusive luxation, extrusive luxation and avulsion. The results obtained allow us to determine 20% of clinical sequelae in permanent successor teeth, with enamel opacities with 88% more frequent injuries, then the enamel hypoplasias reached 12%. Most of the injuries recorded as mild severity are of type (65%) and the percentage of teeth with clinical sequelae not changes significantly across the different diagnoses. The average age when children suffer the trauma and had sequelae was 4.7 years. No cases of extrusive luxation since there were no cases with sequelae. It is concluded that the permanent teeth that replace primary teeth that have suffered trauma such as intrusive luxation, subluxation, lateral luxation and avulsion, often have consequences that are expressed mainly as opacity and enamel hypoplasia. The aftermath of this trauma could be reduced if children exposed to these lesions are entered into early health centers specialized in the care of dentoalveolar trauma.
