Apical periodontitis
Apical periodontitis is an inflammatory lesion in the periodontal tissues that is caused mostly by bacterial elements derived from the infected root canal system of teeth (Core concept 7.1). In non-treated teeth apical periodontitis represents a defensive response to a primary infection in a necrotic pulp. Apical periodontitis may also develop due to a secondary infection subsequent to endodont...
متن کاملInfluence of the Quality of Root Canal Treatment and Crown Restoration on the Prevalence of Apical Periodontitis
Introdouction: The high prevalence of apical periodontitis (AP) of endodontic origin raises an important public health problem. Root canal treatment (RCT) and crown restoration (CR) have an effect on its prevalence. This cross-sectional study was performed to assess the effect of RCT and CR on the prevalence of AP. Materials and methods: Two observers assessed 608 teeth with RCT belonging to p...
متن کاملYeasts in apical periodontitis.
Microbiological reports of apical periodontitis have revealed that yeasts can be isolated from approximately 5-20% of infected root canals. They occur either in pure cultures or together with bacteria. Almost all isolated yeasts belong to the genus Candida, and the predominant species is C. albicans. Pheno- and genotypic profiles of C. albicans isolates show heterogeneity comparable with those ...
متن کاملTreatment options for teeth with open apices and apical periodontitis.
Three clinical cases involving teeth with open apices and apical periodontitis were treated using different protocols. The first case was managed with intracanal calcium hydroxide paste for 12 months before obturation with gutta-percha and sealer. In the second case, an apical plug of mineral trioxide aggregate (MTA) was used before obturation with gutta-percha and sealer and treatment was comp...
متن کاملNon-microbial etiology: periapical cysts sustain post-treatment apical periodontitis
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 ...
