La irrigación es una parte vital de la terapia del conducto radicular, porque se necesita un sistema eficiente para eliminar los desechos, disolver tejido orgánico, eliminar microorganismos, subproductos microbianos y la capa de frotis. La investigación realizada busca comparar la cavidad de tejido pulpar remanente a 3mm, 6mm y 9mm del ápice radicular en conductos ovalados y redondos de premolares instrumentados con el sistema Reciproc después de la activación del irrigante con el Endofinisher, Endoactivador, Easy clean y jeringa convencional. Encuentra que el diseño del estudio fue experimental in vitro; el tipo de investigación prospectivo, exploratorio y longitudinal. La muestra se clasificó aleatoriamente en cuatro grupos experimentales, constituidos por 10 premolares con conducto de configuración redonda y 10 premolares con conducto de configuración ovalada; se formó cua...

Objective: To identify the prevalence of musculoskeletal disorders (MSDs) among members of the Peruvian Society of Endodontics. Materials and methods: The Kuorinka Nordic Musculoskeletal Questionnaire was distributed to members of the society and administered online via Google Forms. Of the responses received, 135 that met the inclusion criteria were analyzed. Results: 66.67% of respondents reported the neck as the area most affected by musculoskeletal disorders (MSDs), with 62.22% reporting this discomfort in the same area during the past week. In contrast, the elbow and forearm showed the least involvement, with a prevalence of 14.07% in the overall analysis, which decreased to 13.33% in the last 12 months and to 6.67% during the past week. Binary logistic regression analysis showed that gender was a significant predictor of MSDs in the neck (OR = 6.01; p < 0.001) and shoulder (OR =...
