Introduction: Dental trauma is a frequent occurance in Dentistry. They often occur in early childhood, between 0 to 3 years old, when children begin to learn their first steps, to play and run, because their habilities are not refined. Objective: The purpose of this article is to verify the occurance of traumatic dental injury in primary teeth in a children population. Material and Method: seventy-eight child from 0 to 6 years old male and female were evaluated. The study was conducted in Regional Hospital of Presidente Prudente. Children were evaluated by a questionary about occurance of traumatic injury, cause and search for attendance. The data were collected and submited to Spearman correlation test. Results: Traumatic dental injury occurs in deciduous teeth in (44,8%) of the population, more common in males (68,5%), at two years old (28,5%) and in front superior region (91,5%) in the upper central incisors (48,5%). Conclusion: By the use of correlation test of Spearman, it was possible to verify that there is a positive correlation between the factors: darkness and mobility, darkness and search for treatment, early loss and satisfactory treatment and search for treatment and satisfactory treatment.Descriptors: Tooth Injuries; Dentition; Dental Care.ReferênciasAssunção LRS, Cunha RF, Ferelle A.

Introdution: The occlusal surface of the molars are more susceptible to dental caries because of their anatomy, so in some cases, the sealants are indicated. Objective: The objective of this study was to evaluate the efficacy, retention, presence of caries and marginal discoloration of resinous sealants (Fluoroshield and Prevent) in first permanent molars. Methods: Ninety - one children aged 7 to 9 years were selected from a municipal institution Regente Feijó, SP, Brazil, for the application of resinous sealants to first permanent lower first molars. The application of Fluoroshield and Prevent resin sealants was performed according to the manufacturer's recommendations. The evaluation was performed after 6 and 12 months by double-blind examiners and followed the criteria: alpha (total sealant, absence of caries and absence of pigmentation) charlie (partial sealing, superficial caries and light pigmentation) charlie complete sealing, presence of cavitation and pigmentation) after 12 months of application by two previously calibrated examiners. Results: Using Fischer's exact test, no significant difference (p 0.05) was observed between the resin-based sealant groups. In the evaluated criteria, both sealants after three years were similar, and may therefore be suitable materials for sealing grooves and fissures in permanent molars.Descriptors: Pit and Fissure Sealants; Dental Caries; Dentition, Permanent; Oral Health.ReferencesPalma-Dibb RG, Chinelatti MA, Souza-Zaroni WC.
