RESUMO
As drogas utilizadas para prevenção de convulsões podem impactar na movimentação dentária durante o tratamento ortodôntico. O objetivo deste estudo foi avaliar a influência de drogas anticonvulsivantes no tratamento ortodôntico. O desenho deste estudo é uma revisão narrativa da literatura onde uma busca eletrônica foi realizada sem restrição de idioma e data em três bases de dados (PubMed via MEDLINE, SCOPUS e BVS). Foram utilizados os seguintes termos para o PubMed e BVS: anticonvulsants drugs AND orthodontic movement e para o SCOPUS: anticonvulsants AND drugs AND orthodontic AND movement. Uma pesquisa complementar foi realizada nas referências bibliográficas dos estudos incluídos. Os artigos indicaram que o uso de medicação anticonvulsivante favorece o desenvolvimento de hiperplasias gengivais, xerostomia e alterações no metabolismo ósseo que modulam a taxa de movimentação ortodôntica. Dentro das limitações desta revisão, concluiu-se que não há contraindicações para tratamento ortodôntico em pacientes utilizando anticonvulsivantes, no entanto os ortodontistas devem estar cientes dos potenciais efeitos adversos advindos do uso desses medicamentos para que possam adotar medidas para mitigar esses riscos.
Drugs used to prevent seizures can have an impact on tooth movement during orthodontic treatment. This study aimed to evaluate the influence of anticonvulsant medications on orthodontic treatment. The design of this study is a narrative literature review in which an electronic search was carried out without language or date restriction in three databases (PubMed/MEDLINE, SCOPUS, and BVS). The following terms were used for PubMed and BVS: anticonvulsants drugs AND orthodontic movement and SCOPUS: anticonvulsants AND drugs AND orthodontic AND movement. A complementary search was carried out on the bibliographical references of the included studies. The articles indicated that using anticonvulsant medication favors the development of gingival hyperplasia, xerostomia, and alterations in bone metabolism that modulate the rate of orthodontic movement. Within the limitations of this review, it was concluded that there is no contraindication for orthodontic treatment in patients using anticonvulsants. However, orthodontists should be aware of the potential adverse effects arising from the use of these drugs so that they can adopt measures to minimize these risks.
RESUMO
The aim of this study was to analyze, in vitro, the reduction of Enterococcus faecalis in root canals of primary teeth after final irrigation and photodynamic therapy (PDT) use. Twenty primary molars were contaminated with Enterococcus faecalis. The teeth were randomly distributed into four groups according to the irrigation solutions and PDT use: G1 (Saline solution and no PDT use), G2 (17 % EDTA and no PDT use), G3 (Saline solution and PDT use) and G4 (17 % EDTA and PDT use). For PDT, 0.005 % toluidine blue was chosen as the photosensitizer, which was inserted in the canals with sterile paper cones. Bacterial counts were performed with a BHI test in blood agar plate, where bacteria were collected inside the canal for 30 s using sterile paper cones. The collection took place before and after the irrigation and PDT protocols. The samples were diluted, spread onto a blood agar plate and then incubated at 37 °C for 24 h. There was a reduction of the microbiota from the irrigation solutions before and after the final irrigation for all groups. It was observed a statistically significant reduction (p < 0,05) when PDT was used (97.6 % at the saline solution and 89.8 % at the 17 % EDTA) when compared to the groups with no PDT use. Our data demonstrated that PDT, according to the parameters used, increased the disinfection performance of the solutions tested in the root canals of primary teeth.
