Abstract(s)
A irrigação é essencial para o sucesso de um tratamento endodôntico por ser responsável pela
eliminação dos microrganismos presentes no sistema de canais radiculares.
Objetivo: Quantificar o volume de irrigante utilizado durante a instrumentação endodôntica e
o tempo de irrigação durante o protocolo final de irrigação (PFI) de um tratamento
endodôntico não cirúrgico em diferentes tipos de dentes.
Métodos: Foram observados 41 tratamentos completos. Durante a recolha de dados mediu-se
o volume de hipoclorito de sódio (NaOCl) usado durante a instrumentação (irrigação inicial),
e o tempo de irrigação durante o PFI. Os irrigantes utilizados foram NaOCl 5%, Ácido Cítrico
(AC) 10% e Álcool 96%. Os dados obtidos foram analisados utilizando o programa de análise
estatística SPSS® v.24.0. (a=0,05).
Resultados: Na amostra total, o valor médio de NaOCl usado foi 29 ml, o tempo de injeção
no PFI de NaOCl foi 01,43 segundos, AC - 01,49 segundos e Álcool - 0,24 segundos. No
grupo de casos monocanalares, o valor mediano de NaOCl usado foi 20 ml, o tempo de
injeção no PFI de NaOCl - 01,41 segundos, AC - 01,36 segundos e Álcool - 0,21 segundos.
No grupo de casos multicanalares, o valor mediano de NaOCl usado foi 40 ml, o tempo de
injeção no PFI de NaOCl - 01,39 segundos, AC - 01,39 segundos e Álcool - 0,20 segundos.
Conclusões: Verificaram-se diferenças estatísticas significativas. O volume de NaOCl
utilizado na instrumentação e o tempo de injeção dos irrigantes no PFI, utilizado pelos
operadores, segue o que é indicado na literatura.
Irrigation is essential for successful endodontic treatment because it is responsible for the elimination of microorganisms present in the root canal system. Objective: To quantify the volume of irrigant used during endodontic instrumentation and irrigation time during the final irrigation protocol (PFI) of a non-surgical endodontic treatment in different types of teeth. Methods: 41 complete treatments were observed. During data collection the volume of sodium hypochlorite (NaOCl) used during instrumentation (initial irrigation), and the irrigation time during the PFI were measured. The irrigators used were NaOCl 5%, Citric Acid (AC) 10% and Alcohol 96%. The data obtained were analyzed using the statistical analysis program SPSS® v.24.0. (a = 0.05). Results: In the total sample, the mean NaOCl value used was 29 ml, the injection time in the PFI of NaOCl was 01,43 seconds, AC – 01,49 seconds and Alcohol – 0,24 seconds. In the group of monocanals cases, the median value of NaOCl used was 20 ml, the injection time in the PFI of NaOCl – 01,41 seconds, AC – 01,36 seconds and Alcohol – 0,21 seconds. In the multicanals case group, the median value of NaOCl used was 40 ml, the injection time in the PFI of NaOCl – 01,39 seconds, AC – 01,39 seconds and Alcohol – 0,20 seconds. Conclusions: Significant statistical differences were verified. The volume of NaOCl used in the instrumentation and the time of injection of the irrigators in the PFI, used by the students, follows what is indicated in the literature.
