These teeth received score 3 (failure) (original magnification ×100).

Acute periradicular inflammation can develop as a result of any type of insult from the root canal system. Regardless of the type of injury, the intensity of the inflammatory response is directly proportional to the intensity of the tissue injury (Siqueira 1997, Trowbridge & Emling 1997).

It is important to note that not all inflammatory changes in the periodontium are due to pulpal demise. It can occur as a result of periodontal disease or occlusal disharmony or periradicular … In the dental specialty of endodontics, periradicular surgery is surgery to the external root surface. Examples of periradicular surgery include apicoectomy, root resection, repair of root perforation or resorption defects, removal of broken fragments of the tooth or a filling material, and exploratory surgery to look for root fractures. Symptoms may be due to infection in the periradicular tissue around a root … periapical abscess inflammation with pus in the tissues surrounding the apex of a tooth.

Chronic apical periodontitis is 2020-06-19 caused primarily by microbial injury to the periradicular tissues and to some extent by chemical and mechanical iatrogenic factors. The offending agents cause inflammation in the periradicular tissues ulting in pain and swelling. The extent of inflammation is proportional to the extent of injury caused to the periradicular tissues. 2021-01-08 Multimicrobial infection of the dental pulp triggers inflammatory responses and ultimately causes bone destruction in the periradicular tissues. Besides bacteria, noxious substances such as degraded protein components and cholesterol could also act as antigens and elicit a host response, which can be harmful to periradicular tissues.

No statistically significant differences were detected in the inflammatory infiltrate between periradicular granulomas and cysts. Observation of the sections showed that the majority of inflammatory cells consisted of T and B lymphocytes and macrophages. T and B lymphocytes were equally distributed in 60% of the cases. Although endodontists concern themselves primarily with inflammatory disease, constant vigilance should be maintained so that the diagnosis of periradicular malignant disease is not delayed. This article reviews oral lymphoma and presents two cases that illustrate the difficulty that can be encountered in establishing a timely and accurate diagnosis.

Tissue inflammation can occur, with the forming of abscesses, granulomas and cysts, internal and / or external inflammatory pathological resorptions of the primary tooth root and of the periradicular bone tissue, loss of the gubernacular channel and alterations in the germ formation of the permanent successor teeth. 17, 19 Besides this, points of infection related to a primary tooth can have a 2006-01-01 In fact, periradicular inflammation can be observed even before the entire root canal is necrotic (5-7). Therefore, the early colo-nizers play an important role in the initiation of the apical periodontitis disease process. The environmental condi-tions in the canal are modified by pioneer species and the absence of periradicular inflammation (API) or (b) presence of periradicular inflammation (PPI).

Contraction of the abutting adjacent bone accompanies the vascular amplification and localized inflammation. Bone absorption occurs besides the fibroblastic and endothelial proliferation which constitutes the fibrils with tiny vascular conduits. Multimicrobial infection of the dental pulp triggers inflammatory responses and ultimately causes bone destruction in the periradicular tissues. Besides bacteria, noxious substances such as degraded protein components and cholesterol could also act as antigens and elicit a host response, which can be harmful to periradicular tissues. established.
