The goal of this study was to estimate the three-fold prevalence of: oral soft tissue lesions, dental trauma to anterior deciduous teeth in relation to the child s age, and sequelae to deciduous teeth and their successors. This research also investigated whether the sequelae in the permanent tooth had an association to the type of dental injury on their predecessor at the time of trauma occurrence in children with 0-10 years of age. Data was obtained from 1230 dental records and clinical exams from children aged 0-10 years at the period of March 1996 to December 2010 that attended the Extension Project in Dental Traumatology on Pedodontics from the University of FOUERJ whose legal guardians signed a consent form approved by the Ethics Committee of HUPE. This sample was constituted of 764 anterior traumatized deciduous teeth obtained from 459 (37.3%) dental records. Statistical analyses χ2 and Mantel-Haenszel s χ2 was performed. Gingival (9.4%) and lip laceration (5.6%) were the most prevalent oral soft tissue lesions. Intrusive luxation (27.8%) was the most frequent type of dental injury on 0-3 years old children followed by avulsion (14.8%). The most common sequelae to deciduous teeth were premature loss (30.3%) and enamel color alteration (26.9%). Succedaneums teeth presented enamel color alteration (26.0%) and enamel hipoplasia (24.5%) in most sequelae cases. The [0,1] year old group registered a statistical significance (P = 0.007) when analyzed separately. A second statistical analysis displayed a significant difference at the (5-10] year old group (P =0.023). Gingival laceration was the most prevalent lesion. Intrusive luxation was the most prevalent type of injury among the 0 to 3 year old children. Premature loss was the most prevalent sequelae in deciduous dentition while in the permanent one enamel color alteration prevailed. An association was detected at the [0-1] year old group and intrusive luxation lead to a great number of enamel hipoplasia. There was also a positive association at the (5-10] year old group. Intrusive luxation leaded to a higher prevalence of eruption alteration.
