Abstract
El éxito del tratamiento de conductos ha de iniciarse con una correcta apertura y localización de conductos, esto implica el conocimiento interno del sistema radicular y de las posibles variaciones anatómicas.En trabajos publicados queda de manifiesto que las complejidades anatómicas tienen una relación directa con la patología periapical persistente conduciendo al fracaso del tratamiento, siendo la incapacidad visual para diagnosticar y tratar los conductos una de las causas de dicho fracaso.Por ello, la necesidad de incorporar nuevas tecnologías que permitan mejorar la visibilidad a la cavidad de acceso para la localización de la entrada de los conductos radiculares.Objetivos:El presente estudio tiene como objetivos; evaluar la eficacia de tres métodos complementarios de ayuda para la localización de conductos radiculares: microscopio óptico,ultrasonidos y tintes, al utilizarlos de forma combinada y secuencial durante el tratamiento endodóntico de molares. Y además determinar la relación existente entre la experiencia del operador y la eficacia de los métodos antes mencionados.Material y métodos:El estudio se realizó en la clínica odontológica de la Institución Universitaria Mississippi, a lo largo de un periodo de 18 meses. Se seleccionaron 202 molares de pacientes que acudieron a consulta por orden cronológico y que necesitaban tratamiento de conductos. Los molares objeto de estudio se dividieron en 4 grupos en función del diente tratado; Grupo 1: primeros molares superiores. (n=51), Grupo 2: segundos molares superiores. (n=50), Grupo 3: primeros molares inferiores. (n=51), Grupo 4: segundos molares inferiores. (n=50)...
The success of root canal treatment has to start with a correct opening and location of the canals; this implies the internal knowledge of the root system and of the possible anatomical variations.In published papers it is clear that anatomical complexities have a direct relationship with persistent periapical pathology leading to a treatment failure, being the visual inability to diagnose and treat the canals one of the causes of this failure.Therefore, the need to incorporate new technologies that allow us to improve visibility to the access cavity for the location of the entrance of the root canals. Objectives: The present study has the following objectives; evaluate the effectiveness of three complementary methods of aid for the localization of root canals: optical microscopy, ultrasound and dyes, when used in combination and sequentially during the endodontic treatment of molars. And also to determine the relationship between the experience of the operator and the effectiveness of the above mentioned methods. Material and methods: The study was carried out in the dental clinic of the Mississippi University Institution, over a period of 18 months. 202 molars were selected from patients who attended the clinic in chronological order and that needed root canal treatment. The molars under study were divided into 4 groups based on the treated tooth; Group 1: first upper molars. (n = 51), Group 2: second upper molars. (n = 50), Group 3: lower first molars. (n = 51), Group 4: lower secon dmolars. (n = 50)...
