Two endodontics techniques analysis in primary molars with fistula

Abstract

Objective The purpose of this research was to follow the radiolucent area (pixels) in the furcation area and the behavior of the endodontically treated deciduous molars with different simplified echniques. MethodsThe treatments were performed without the duct instrumentation using relative isolation and two drugs were applied, as follows: G1: GuedesPinto paste (GP) was used and for comparison of the initial radiographic image, analysis of variance was used after 6 and 12 months of each group and Tukey spost-hoc test. T-Student test was used for comparison between groups. Results There was a reduction of radiolucent area after 6 (p<0.01) and 12 months (p<0.01) in the teeth treated with CTZ paste. In the teeth treated with PG there was not reduction of radiolucent area after 12 months. (p= 0,09). ConclusionAlthough the clinical signs were similar in both groups after 12 months of follow up, only teeth treated with CTZ showed reduction of radiolucent area in the furca area after 6 and 12 months.Indexing terms: Primary tooth.

RESUMO ObjetivoA proposta da pesquisa foi acompanhar a area radiolúcida (pixels) na região de furca e a resposta clínica de molares decíduos tratados endodonticamente com diferentes tecnicas simplificadas. MétodosOs tratamentos foram executados sem instrumentação dos condutos e com isolamento relativo, utilizando-se dois medicamentos: G1:Pasta Guedes-Pinto (PG) e G2: Pasta CTZ (CTZ) no preenchimento da câmara pulpar . As áreas radiolúcidas na região de furca dos molares decíduos obtidas das radiografias antes, após 6 meses e 12 meses do tratamento endodôntico foram analisadas no programa Image Tool 3.0 por 2 examinadores cegos. Para analisar a calibração entre os examinadores foi utilizado o teste Kappa e para comparação da imagem radiográfica inicial, após 6 e 12 meses de cada grupo foi utilizado a Análise de Variância e o teste complementar de Tukey. O teste T Student foi usado para comparação entre os grupos. ResultadosA redução da área radiolúcida inicial após 6 (p<0,01) e 12 meses (p<0,01) foi observada somente com o uso da pasta CTZ. O emprego da pasta Guedes não resultou em diminuição da área radiolúcida após 12 meses de acompanhamento (p=0,09). ConclusãoA resposta clínica foi semelhante em ambos os grupos, porém apenas os dentes tratados com a pasta CTZ apresentaram redução da área radiolúcida na região da furca após 6 e 12 meses de acompanhamento.Termos de indexação: Dente decíduo.

Do Different Proportions of Antibiotics in the CTZ Paste Interfere with the Antimicrobial Action? In Vitro Study

“…In clinical practice, the use of CTZ paste in necrotic primary molars showed promising clinical and radiographic results [6]. In most of the studies, CTZ is used in a 1:1:2 ratio, 25% of chloramphenicol, 25% of tetracycline and 50% of zinc oxide, mixed with Eugenol [1,[5][6][7][8][9][10][11][12].…”

Cost analysis of endodontic treatment in primary teeth: results from a randomized clinical trial

“…Public Health Services lack simplified treatment protocols that can be performed by general practitioners, reducing the demand for certain dental treatments. 8 Currently, in many healthcare systems, primary teeth do not receive endodontic treatment due to complexity of the technique. 31 Failure to treat a primary tooth with irreversible pulpitis or pulp necrosis can damage the permanent successor and negatively impact the child's oral health and quality of life.…”

“…7 Some important advantages of the CTZ paste technique is that it does not require rubber dam isolation of operative field, instrumentation, and root canal obturation. 2,7,8 A non-instrumental endodontic treatment (NIET), also known as lesion sterilization and tissue repair (LSTR), aims to repair damaged tissues by disinfecting affected pulp and periapical regions with a mixture of antibiotics. 9 These characteristics reduce the clinical time of therapy, and hence, it is more favorable for pediatric dental care, specifically in the public service and for patients with difficult management.…”

Pasta CTZ para abordaje endodóncico de dientes primarios: Una revisión narrativa de la literatura

“…La pasta antibiótica CTZ, que contiene una mezcla de cloranfenicol, tetraciclina, óxido de zinc y eugenol, fue propuesta en 1965 y 1967 por Cappiello 3,4 para este tratamiento, ha sido utilizada en América Latina a pesar de la limitada cantidad de estudios clínicos. [5][6][7][8][9][10] Esta pasta tiene la ventaja de ser de fácil y rápido uso, en una sola sesión clínica. Sin embargo, los resultados reportados en la literatura sobre el éxito clínico de esta intervención no se han mostrado tan favorables durante la monitorización radiográfica de las lesiones.…”
