Aim: Traumatic dental injuries occur frequently in children. Treatment and follow ups are important to avoid short and long term complications. The aim of this study was to investigate the prevalence of sequelae in the permanent anterior teeth following the trauma in their predecessors in the period of 2005 to 2011. Methods: This study was performed retrospectively according the data from the records of 79 children (53 boys, 26 girls), who were treated for anterior deciduous tooth trauma. Of

... 79 affected children (186 teeth), 35 (91 teeth, 22 boys and13 girls) were available for the follow-up examination. Kappa coefficient was calculated for inter-examiner reliability. Descriptive statistics including percentage and mean values were also calculated. Results: Sequelae were detected on 45(49.5%) of 91 successors of the traumatized deciduous teeth and enamel hypoplasia and/or discoloration was observed in 14 (31.1%) teeth. Eruption was disturbed in 14 (31.1%). In 13 teeth (28.9%) crown and root malformation, in three teeth (6.7%) only crown and in one tooth (2.2%) only root malformation was detected. Most frequent sequela of successors were observed after the intrusive luxation of the deciduous teeth (33%). Crown-root malformations of the successor teeth were most frequently occurred after the trauma at the age of 0 to 2 (61.53%). Conclusions: Early diagnosis and treatment of primary dental injuries and routine clinical and radiological follow up would minimize the sequelae which were observed in permanent successors..
