Analysis of stresses on primary anterior teeth during trauma : Influence of root resorption of mandibular primary central incisors

Abstract

Trauma to primary incisors occurs during childhood not only in the maxilla, but also in the mandible. It has been postulated that damage to the primary dentition is related to the degree of root resorption. We used a computer simulation and the finite element method to analyze stresses during trauma to the mandibular primary incisors. We concluded that damage to the periodontal tissue was greater when there was root resorption, while damage to the teeth was greater when there was not.
