Periapical Inflammation (periapical + inflammation)
Selected AbstractsPeriapical Inflammation After Coronal Microbial Inoculation Of Dog Roots Filled With Gutta-percha Or ResilonAUSTRALIAN ENDODONTIC JOURNAL, Issue 1 2005Article first published online: 11 FEB 2010 No abstract is available for this article. [source] Longitudinal tooth fractures: findings that contribute to complex endodontic diagnosesENDODONTIC TOPICS, Issue 1 2007ERIC M. RIVERA The purpose of this review is to describe and discuss the diagnostic and treatment challenges related to tooth fractures primarily in the vertical plane, that is, the long axis of the crown and/or root. This includes when and how to identify and determine the extent of the fracture, when a coronal restoration should be placed, when root canal treatment is needed, and when a tooth or root should be extracted based on the location and extent of the fracture. The term ,longitudinal fractures' is used because they usually represent vertical extensions of fractures over distance and time. These fractures often present problems with diagnosis and treatment, but should be considered as findings only. They are not to be considered as pulpal or periapical diagnoses, but as pathways for bacteria that may induce pulpal and/or periapical inflammation or disease. Longitudinal fractures are divided into five definitive classifications, generally from least to most severe: (1) craze lines; (2) fractured cusp; (3) cracked tooth; (4) split tooth; and (5) vertical root fracture. These differ but have frequently been confused or combined in clinical articles, creating misunderstanding and resulting in incorrect diagnosis and inappropriate treatment. These classifications have been devised to provide global definitions that researchers and clinicians can use to eliminate this confusion. This review is subdivided into these five classifications as to incidence, pathogenesis, clinical features, etiologies, diagnosis, treatment, prognosis, and prevention.

Bernabé Abstract Aim, To assess the histological response associated with grey mineral trioxide aggregate (GMTA) and zinc oxide eugenol (ZOE) as root-end filling materials in teeth where the root canals were not filled and the coronal access cavities were not restored. Methodology, Periapical lesions were developed in 24 premolar teeth in three dogs. The root canals were prepared and half of them were dried, filled and the coronal access restored (closed). The remaining teeth were not root filled and no coronal restoration was placed (open). Apical root-end resections were performed 3 mm from the apex, and root-end cavities were prepared with ultrasonic tips. These were randomly filled with either ZOE or GMTA in the same number of specimens using MAPSYSTEM device. After 180 days the animals were killed and blocks of tissues removed and processed for histological examination. Periradicular tissue reaction was evaluated, including severity of inflammation and cementum formation. Statistical analysis was performed using anova analysis and Tukey's test. Results, A significant difference was found between the levels of inflammation in the periradicular tissues of the GMTA/closed group, compared with the ZOE/open and ZOE/closed groups (P < 0.05) but not between GMTA/closed and GMTA/open groups. Cementum formation was not found over any ZOE specimens but over MTA in all specimens. No microorganisms were found in the interface between the material and the dentinal walls. Conclusions, GMTA was associated with less periapical inflammation and tissue response when used as a root-end filling material, even when no root filling or coronal restoration was present.
