ABSTRACT
Introduction: The presented study aimed to characterise periapical disease in teeth with primary non-surgical root canal treatment in persistent or emergent categories and their risk association. Methods: A retrospective observational study that evaluated permanent teeth with primary non-surgical root canal treatment, was conducted clinically and radiographically for over one year. The following variables were analysed: gender, age, type and location of tooth, previous diagnosis, treatment conditions, and type of coronal restoration. The supplementary variables included the perspectives of the treatment outcome, such as Remains normal, Improvement, and Failure. Statistical analysis was performed using a univariate analysis that estimated the average and proportion for each factor according to the result of the primary non-surgical root canal treatment. The multiple correspondence analysis identified the hierarchy between active variables and their association with the results. Results: A total of 232 teeth in 155 participants were analysed. A χ2 value, (P=0.023) showed that the emergent disease is associated with patients around the age of 50. The multiple correspondence analysis identified a tendency of grouping between the emergent disease and the short filling category, followed by symptomatic pulpitis as a previous diagnosis. The persistent disease was associated with errors and overfillings. An inadequate root filling and taper density adversely impacted the treatment outcome. Conclusions: The length of obturation influenced the presence of failure. Short fillings were associated with emerging periapical disease. Errors and overfillings contributed to the persistent disease in the populations studied.
ABSTRACT
Objetivo: caracterizar la enfermedad periapical posterior al tratamiento endodóntico primario realizado en una cohorte de individuos asistentes a las clínicas de la Especialidad en Endodoncia de la Facultad de Odontología de la Universidad Nacional de Colombia. Métodos: se realizó un estudio observacional retrospectivo en una muestra de 232 dientes con tratamiento endodóntico primario, procedentes de 155 individuos. Un análisis de frecuencia estimó la prevalencia entre la presencia de enfermedad periapical y las siguientes covariables: sexo, edad, tipo y localización del diente, diagnóstico previo, condiciones del tratamiento endodóntico, y tipo de restauración. Resultados: se registró un 24% de prevalencia de enfermedad periapical en la población observada. De este porcentaje, el 13,7% fue categorizado como EPE y el 10,3% fue categorizado como EPP. La distribución por sexo fue de 59% para mujeres y 41% para hombres, con promedio de edad de 55,8 años. La prevalencia de la enfermedad fue mayor en molares (44%) y el diagnóstico pulpar más frecuente fue necrosis pulpar (34%). El 20% de los tratamientos analizados presentó longitud de obturación corta y, de ellos, el 54,3% se asoció con aparición de la enfermedad. Conclusiones: la longitud de obturación corta resultó ser el factor que registró mayor relación clínica con la aparición de la enfermedad. Se reconoce a la EPE como el verdadero fracaso del tratamiento endodóntico primario.
Objetive: Identify the characteristics of the periapical disease in the primary endodontic treatment, in teeth to individuals person that included in the Speciality in Endodontics of the Faculty of Dentistry of the Universidad Nacional de Colombia. Methods: Retrospective observational study in a population of 232 teeth from 155 individuals with primary endodontic treatment. A frequency analysis was performed, estimating the prevalence between, the presence of periapical disease and the covariables sex, age, type and location of tooth, previous diagnosis, conditions of endodontic treatment and type of restoration. Results: For the total study population, 24% has been periapical postreatment disease, was categorized in 13,7% as EPD and 10,3% as PPD. The distribution by sex included 59% women and 41% men, age average of 55,8 years. 20% of the analyzed treatments presented a short obturation length, of which 54,3% were associated with EPD. Conclusions: The short obturation length proved to be the factor that registered the greatest clinical relation with the onset of the disease. EPE is recognized as the true failure of primary endodontic treatment.
