RESUMO

Objective: Determine the prevalence of injuries due to dislocation in the primary dentition and the associated sequelae in children treated at Pediatric Dentistry Clinic of the School of Pharmacy, Dentistry and Nursing, Federal University of Ceará. Material and Methods: The research protocol was reviewed and approved by the Institutional Research Ethics Committee Medical School of the Federal University of Ceará, Fortaleza, Ceará, Brazil. It was conducted through a transversal retrospective observational investigation. Data were collected from the medical records from 2000 to 2014. We use the statistical analysis software SPSS (Statistical Packacge for the Social Sciences) 17.0 for Windows. Results: The sample consisted of 52 patients, totaling 75 traumatized primary teeth. The average age at injury was 37.6 months and the most affected gender was male (65.4 %). Most injuries occurred at home (57.7 %) and consequently to fall from height (73%). The most common type of dislocation for injury was intrusion (53.3 %) and color change (42.7%), pulp necrosis (37.3 %) and obliteration of the root canal (13.3%) the most frequent sequelae. Conclusion: The high prevalence of sequelae (74.7 %) shows that proper treatment should happen at right time in order to reduce the occurrence of sequelae. (AU)


Objetivo: Determinar a prevalência de lesões por luxação na dentição primária e as sequelas associadas em crianças atendidas na Clínica de Odontopediatria da Faculdade de Farmácia, Odontologia e Enfermagem da Universidade Federal do Ceará. Material e Métodos: O protocolo de pesquisa foi revisado e aprovado pelo Comitê de Ética em Pesquisa Institucional da Faculdade de Medicina da Universidade Federal do Ceará, Fortaleza, Ceará. Este estudo foi realizada através de uma investigação observacional retrospectiva transversal. Os dados foram coletados dos registros médicos entre os anos 2000 e 2014. Utilizamos o software de análise estatística SPSS (Statistical Packacge for the Social Scientes) 17.0 para Windows. Resultados: A amostra foi composta por 52 pacientes, totalizando 75 dentes primários traumatizados. A idade média de lesão foi de 37,6 meses e o sexo mais atingido foi o sexo masculino (65,4%). A maioria das lesões ocorreu em casa (57,7%) e, consequentemente, a queda de altura (73%) foi o motivo mais de maior prevalência. O tipo mais comum de luxação por lesão foi a intrusão (53,3%) e alteração de cor (42,7%), necrose pulpar (37,3%) e obliteração do canal radicular (13,3%) as sequelas mais frequentes. Conclusão: A alta prevalência de sequelas (74,7%) mostra que o tratamento adequado deve ocorrer no momento adequado para reduzir sequelas.(AU)

RESUMO

To evaluate the use of electronic apex locator to measure the root canal length in primary teeth, comparing this measure with the measurements obtained by conventional radiography and by the direct measurement of the root canal lenght.Material and Methods:The sample consisted of nine multi-rooted primary teeth, totaling 32 root canals. Endodontic access was performed with a spherical diamond tip, then the pulp was extirpated and the canal irrigated with 0.9% saline. An endodontic file was used to measure the root canal length by electronic apex locator, using the Novapex ® according to the manufacturer's instructions, and by direct method. An endodontic ruler was used to determine fileÆs length. Conventional radiographic was also performed. Statistical analysis was performed by analysis of variance (ANOVA). The level of significance was 95%.Results:The average of the root canal length was 9.98 ± 2.16 to the direct method; 11.52 ± 1.87 to conventional radiography; and 10.91 ± 1.92 to the electronic apex locator. The results of this study showed a high correlation between the values given by the different methods, regardless of the presence or absence of physiological root resorption. There were not statistically significant differences amongst the methods studied (p> 0.05).Conclusion:Electronic apex locator was an accurate method measure the root canal length in primary teeth, and its use is indicated in endodontic treatment of these teeth...
