Post treatment periapical periodontitis is usually caused by residual microbes, due to poorly treated root canals and microleakage. Our clinical case proved that orthograde, single-visit endodontic re-treatment is the first choice for the clinician. Cone Beam Computed Tomography (CBCT) images detect the presence and the real extension of the periapical periodontitis and the outcome of the endod...

OBJECTIVE To evaluate the periapical repair after root canal treatment in the teeth of dogs using CT and conventional radiography and to compare these findings with the gold standard microscopic evaluation. STUDY DESIGN The animals were divided into three groups according to endodontic treatment performed: Group 1, single-visit endodontic treatment in teeth without apical periodontitis; Group...

The radicular cyst has been classified as inflammatory cyst, as a consequence to pulpal necrosis following caries, with an associated periapical inflammatory response. Many times it is d ifficult to differentiate radicular cysts from the obligatory pre-existing chronic periapical periodontitis lesions radiographically. This paper presents a case of radicular cyst in the maxillary anterior region.

The dental pulp space can become infected due to a breach in the surrounding hard tissues. This leads to inflammation of the pulp (pulpitis), soft tissue breakdown, and finally to bone loss around the root apex (apical periodontitis). The succession of the molecular events leading to apical periodontitis is currently not known. The main inflammatory mediator associated with neutrophil chemotaxi...

Root canal samples, taken from periapical tissue exudates during routine root canal treatment procedures, were processed for identification of tumor necrosis factor using a mouse anti-human monoclonal antibody and enzyme-linked immunosorbent assay. Detectable levels of tumor necrosis factor were identified in periapical tissue exudates in chronic 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 ...

The aim of this retrospective investigation was to assess the medical status of the mouth of patients who presented themselves to an endodontist, taking into consideration: patient’s age, reason for coming to a dentist, diagnosed and treated apical periodontitis. Two years’ medical history of patients, who presented themselves to the endodontist, have been studied. In 1995-1996 among 336 patien...

UNLABELLED The aim of this study was to investigate the technical quality of root fillings in root filled teeth, their association with periapical status and prevalence of apical periodontitis. MATERIAL AND METHODS The sample consisted of 83 subjects, presenting consecutively as new patients seeking dental care (prosthetic, endodontic and cariologic treatment) in the years 2005/2006. Clinical...
