Retreatment Efficacy of Endodontic Bioceramic Sealers: A Review of the Literature

The endodontic retreatment is a feasible solution when post-operative apical periodontitis persists or develops. The complete removal of the filling materials is important in order to ensure the unobstructed contact of the intracanal disinfectants with the microbes. As a new generation of bioceramic endodontic sealers has emerged, their removal efficacy from the root canal system during retreatment is a matter of concern among clinicians. The aim of this article is to provide a comprehensive review of the current literature on the retreatability of these novel obturating materials. A significant amount of bioceramic sealer remnants in the root canal walls was observed in all studies.  Even though canal cleanliness could not be obtained at an ideal level, the re-establishment of the working length and patency can be considered manageable and comparable to other endodontic sealers.El retratamiento endodóntico es una solución factible cuando la periodontitis apical post-operatoria persiste o se desarrolla. La eliminación completa de los materiales obturadores es importante para garantizar el contacto y acción de los desinfectantes e irrigantes endodónticos con los microorganismos persistentes. A medida que ha surgido una nueva generación de selladores endodónticos biocerámicos, su eficacia de eliminación del sistema de conductos radiculares durante el retratamiento es motivo de preocupación entre los profesionales. El objetivo de este artículo es proporcionar una revisión exhaustiva de la literatura actual sobre la influencia o posibles limitantes del uso de este tipo de cementos bioactivos durante el retratamiento endodóntico. Los estudios determinaron una cantidad significativa de restos de selladores biocerámicos en las paredes del conducto radicular. Aunque la limpieza del canal no se pudo obtener a un nivel “ideal”, el restablecimiento de la longitud de trabajo y la permeabilidad se puede considerar manejable y comparable a otros selladores endodónticos

Adults with Dental Erosion - Could This Be a Clinical Sign of Anorexia or Bulimia Nervosa? How is a Patient with Eating Disorders Approached?

Rhythms, requirements and standards of modern life have made the anxiety a common feature of most people. Along with stress, several other psychological problems increasingly appear and, unfortunately, critically affect young ages. 2 of the most common chronic mental disorders are anorexia nervosa and bulimia nervosa. Dentists are uniquely positioned because in their area of examination, signs of these diseases can be seen and then their symptoms can be discussed with patients. Nowadays, despite the fact that these diseases are on the rise, dentists do not know enough about them. Often, even if the knowledge is enough to diagnose the disease, they avoid doing it, because they try not to make their patients feel uncomfortable and lose them
