| English abstract | The purpose of this study was to evaluate the clinical performance of brackets cured with two light-curing units. MATERIALS AND METHODS: Forty female patients (between12-16 years old) who required fixed appliances were included in this study. Based on the characteristics of their lower arches, study participants were divided into two groups, A and B. In group A, the composites were cured on the right side by Ultralume LED2TM and on the left side by a conventional halogen unit. In group B, the sequence was reversed. A total of 160 brackets were bonded. After 12 months, bond failure rate was evaluated. RESULTS: We found that 18 brackets in the halogen group and 13 brackets in the LED group were debonded. No statistically significant differences were found in total bond failure rate and no enamel damage was clinically detected for either technique. CONCLUSION: These results suggest that LED dose curing does not result in more bond failure when compared with conventional halogen light curing |
| Portuguese abstract | O objetivo deste estudo foi avaliar o desempenho clínico de brackets colados utilizando-se de duas unidades de polimerização. MATERIAL E MÉTODO: quarenta pacientes adolescentes com indicação de tratamento ortodôntico fixo foram incluídos no trabalho, divididos em dois grupos, A e B. No grupo A, o compósito foi polimerizado no lado direito com Ultralume LED 2TM e no lado esquerdo com luz halógena convencional. No grupo B, a sequencia foi invertida. Um total de 160 brackets foram colados. Após 12 meses de tratamento, avaliou-se a taxa de falhas de colagem. RESULTADOS: 18 brackets no grupo halógeno e 13 no grupo LED sofreram descolamento. Não houve diferença estatisticamente significante na taxa total de falhas e não foram observados danos ao esmalte em ambas as técnicas. CONCLUSÃO: Estes resultados sugerem que a fotopolimerização com LED não resulta em maiores falhas de adesão quando comparadas com a luz halógena convencional |
