“…Both contaminated and uncontaminated dentin and pulp tissue can trigger an inflammatory reaction when forced periapically during instrumentation. 3 The immunologic aspects of postoperative flare ups were assessed by a number of researchers who concluded that antigens originating in the root canal result in the formation of antigen antibody complex which, when forced beyond the apical foramen, can lead to a severe inflammatory response.…”

Clinical significance: The apical extrusion of infected debris may have the potential to disrupt the balance between microbial aggression and host defense, resulting in incidents of acute inflammation. During preparation, irrigants and debris, such as bacteria, dentin filings and necrotic tissue may be extruded into the periradicular region leading to periapical inflammation and postoperative flare ups. Using an instrumentation technique that minimizes apical extrusion would be beneficial to both the practitioner and patient.The purpose of the study was to evaluate the weight of debris and volume of irrigant extruded apically from extracted teeth in vitro after endodontic instrumentation using four different rotary root canal instrumentation systems. Materials and methods:Four groups of each 20 extracted mandibular premolars were instrumented using one of the four systems: ProTaper Universal (Dentsply Maillefer, Ballaigues, Switzerland)), Hero-shaper (MicroMega, Besancon, France), RaCe (FKG Dentaire, La-Chaux-de-Fonds, Switzerland) and K3 (SybronEndo, West Collins, CA). Debris and irrigant extruded from the apical foramen during instrumentation were collected in preweighed test tubes. Volume of irrigant extruded was noted. The containers were stored in incubator at 70° for two days to evaporate the moisture. Weight of dry debris was noted.Statistical analysis: Data was analyzed using Kruskall-Wallis and Mann-Whitney U test at a significance of 0.001. Results:The results indicated that all of the instrumentation systems tested caused measurable apical extrusion of debris and irrigants. Higher extrusion was observed with Protaper system which was statistically significant with Hero-Shaper, RaCe and K3 systems. There were no statistical differences between Hero-shaper, K3 and RaCe systems (p < 0.05). Conclusion:All instrumentation techniques apically extruded debris and irrigant. However, Hero-shaper, K3 and RaCe systems produced less extruded debris and irrigant than the Protaper system.

“…Chemomechanical procedures during root canal preparation may trigger an inflammatory reaction by pushing dentin particles, necrotic pulp tissue and microorganisms from the apical foramen into the periapical region (12). Therefore, reducing the extrusion of debris can minimize the risk of endodontic flare-up.…”

“…Sus resultados mostraron que ninguna técnica es efectiva en prevenir la extrusión de restos a través del foramen apical, pero sí encontraron que fue mayor la cantidad de los mismos cuando se utilizó la técnica de paso atrás. 38 Basados en estos estudios, autores como Fava y Trope utilizan en sus estudios técnicos el ensanchamiento cervical, a fin de disminuir la posibilidad de extruir restos o detritus que puedan desencadenar una agudización endodóntica, y obtenido en sus tratamientos una baja incidencia de agudizaciones.

RESUMENLa agudización endodóntica se caracteriza por el desarrollo de dolor, edema o ambos, posterior a una intervención endodóntica. Generalmente, los factores causantes son: daño mecánico, químico y/o microbiano a la pulpa o tejidos perirradiculares. De todos ellos, los microorganismos son indiscutiblemente el mayor agente etiológico de las agudizaciones. Se presentan varios regímenes de tratamiento para el alivio del dolor durante la terapia endodóntica que incluyen el alivio de la oclusión, premedicación, drenaje y medicaciones sistémicas y dentro del conducto radicular. El objetivo de este primer artículo fue realizar una revisión de la literatura acerca de su definición, incidencia y posibles factores desencadenantes. En la segunda parte se tratará la etiopatogenia y la adopción de medidas preventivas apropiadas para reducir significativamente la incidencia de este indeseable fenómeno clínico. ENDODONTIC FLARE UPS: PART I ABSTRACTInter-appointment flare-ups are characterized by the development of pain, swelling or both, following an endodontic treatment. The etiologic factors of flare-ups included mechanical and/or microbial injury to the pulp or perirradicular tissues. Of these factors, microorganisms are probable the major causative agents of flare-ups. Various treatment regimens for the relief of pain during endodontic therapy, including relief of drainage, and intracanal and systemic medications are presented. The aim of this first paper was to make a literature review about its definition, incidence and relative factors that may cause flare ups. The second paper will review the etiology and some preventive aids to reduce its incidence. INTRODUCCIÓNLa realización de un tratamiento endodóntico es un procedimiento que, por lo general, despierta muchas "expectativas" en el paciente, más aún si éste presenta sintomatología. Posiblemente, se deba a la creencia popular de que los tratamientos de conductos son dolorosos. Aunque uno de sus objetivos es proporcionar alivio al paciente, puede llegar a ser frustrante tanto para el paciente como para el odontólogo, que el tratamiento efectuado ocasione dolor o inflamación; algunas veces llega a ser sorpresiva una sintomatología dolorosa postoperatoria, si el paciente previo a la realización del tratamiento, se encontraba asintomático.La sintomatología que puede presentar un paciente durante la realización de un tratamiento endodónti-co se conoce como agudización endodóntica. Es una complicación que se presenta de manera inesperada durante la terapia endodóntica, sorprende tanto al paciente como al clínico tratante y requiere su pronta atención. De ahí, surge la inquietud por conocer, entre otras cosas, su incidencia y las causas que la producen para manejarla de manera adecuada y prevenir cuanto más sea posible.Se ha reportado gran variación en la frecuencia de flare-ups; parece ser que ocurre en un promedio del 14 al 16%. Ciertos factores influyen significativa-
