ABSTRACT
The aim of this study was to determine the prevalence of sequelae in permanent teeth that had their predecessors traumatized and investigate associated factors. The study was carried out with clinical and radiographic data from 137 patient charts of the Traumatized Patient Care Program, Federal University of Santa Catarina (Brazil), totalizing 253 teeth. Data were gathered on gender, age at the time of trauma, type of trauma, type of post-trauma sequelae, trauma recurrence and crown alteration in the permanent successors. No statistically significant associations were found between permanent successor's crown alteration and gender, age at the time of trauma, post-trauma sequelae or trauma recurrence (p>0.05). Significant associations were found between severe trauma (crown fracture with pulp exposure, lateral luxation, intrusion and extrusion) in the primary incisors and permanent successor's crown alteration (p<0.05). Multivariate analysis revealed an association between severe trauma to the primary incisors and permanent successor's crown alteration (OR 4.1 - IC 1.7-10.1). Alterations in the crown of permanent successors are associated with severe trauma to the primary incisors, as primary teeth affected by severe trauma have a fourfold greater chance of exhibiting permanent successor crown alteration in comparison to primary teeth that had minor trauma.
RESUMO
O objetivo deste estudo foi determinar a prevalência de sequelas nos dentes permanentes, em crianças que tiveram o seu antecessor traumatizado e os fatores associados. O estudo foi realizado com dados clínicos e radiográficos de 173 prontuários de pacientes do Programa de Assistência ao Paciente Traumatizado, Universidade Federal de Santa Catarina (Brasil), totalizando 253 dentes. Os dados coletados foram gênero, idade no momento do trauma, tipo de trauma, tipo de sequelas pós-trauma, recorrência de trauma e alteração na coroa dos sucessores permanentes. Não houve associação estatisticamente significativa entre alteração na coroa do sucessor permanente e gênero, idade no momento do trauma, sequela pós-trauma e recorrência de trauma (p>0,05). Foram encontradas associações significativas entre trauma grave (fratura coronária com exposição pulpar, luxação lateral, intrusão e extrusão) nos incisivos decíduos e o sucessor permanente com alteração na coroa (p<0,05). A análise multivariada revelou uma associação entre trauma grave nos incisivos decíduos e alteração no sucessor permanente (OR 4.1- IC 1,7-10,1). Alterações na coroa dos sucessores permanentes estão associadas com trauma grave nos incisivos decíduos. Dentes decíduos acometidos por trauma grave têm quatro vezes mais chance de apresentar alteração na coroa do permanente em comparação com trauma leve.
