the importance of the role played by bacteria in the pathogenesis of pulpal and apical disease has been established. one of the characteristics of apical periodontitis is apical bone resorption, which is due to apical immune response to bacterial infection. recently, novel bacterial complex lipid called phosphorylated dihydroceramides has been discovered to be of inflammatory activators. the ba...

Tooth autotransplantation, that is the surgical movement of a tooth from its original location to another site within same person, an alternative dental implantation because it can save time, provide faster healing and function, has esthetic advantages. A unique sensory system be maintained, procedure promotes proper periodontal environment. We report on case external fistula with apical period...

INMICROSCOPY, AS INNATURE,ONERECOGNIZESONLYWHATONEALREADYKNOWS. Routine histopathological diagnostic reports and publications based on retrospective reviewing of such, perpetuate the notion that nearly half of all apical periodontitis lesions are cysts. Studies based onmeticulous serial sectioning of apical lesions retrieved in toto show that the actual prevalence of cysts is only about 15% of ...

We report a case of apical fenestration misdiagnosed as persistent apical periodontitis. The patient was a 55-year-old woman who presented with persistent tooth pain at the right maxillary canine, despite repeated root canal treatment by a general practitioner. When the patient visited Tokyo Dental College Suidobashi Hospital, a CT examination was performed and apical fenestration diagnosed. Th...

The purpose of the study was to histologically analyse transition from pulpitis to periapical periodontitis on dog's teeth. Pulps of mandibular premolars (37 roots) were exposed using a low-speed handpiece. Teeth were left open to the oral environment for 20, 35, 50 and 65 days. After the experimental period animals were sacrificed. Undemineralised teeth with surrounding bone, embedded in methy...

Introducción y objetivo: el tratamiento endodóntico se realiza para tratar la enfermedad pulpoperiapical puede tener un porcentaje de éxito más del 90% en condiciones ideales su realización. Dentro los factores que condicionan práctica clínica, encuentran anatomía interna diente, las habilidades operador, conocimiento técnica, instrumentos empleados tiempo operatorio. El lo determina superviven...

Introduction: Primary root canal treatment success depends on a number of variables, including debridement and disinfection of the root canal system to remove all bacteria and diseased pulpal and dentinal tissues. Complex root canal anatomy, such as concealed isthmuses, apical deltas and lateral canals, hinder this objective, making instrumentation of these regions nearly impossible. Recent adv...
