A Consensus Conference on Terminology was convened by the American Association of Endodontists in Chicago on Oct 3, 2008 to review solicited papers on focused questions. This paper addressed the question: Identify and determine the metrics, hierarchy, and predictive value of all the parameters and/or methods used during endodontic diagnosis. The best available clinical evidence was used to dete...

introduction : root-end preparation and restoration with an endodontic material are required when nonsurgical endodontic retreatment has failed or is impossible. the present clinical study reports the treatment outcomes of periradicular surgery using calcium-enriched mixture (cem) cement. materials and methods: a prospective outcome study of periradicular surgery using cem was conducted on 14 p...

Biopsy reports from 150 periradicular tissue specimens obtained from teeth refractory to nonsurgical endodontic therapy were reviewed. The specimens were submitted by postdoctoral dental students in the Department of Endodontics, and the biopsy reports were prepared by oral pathologists at the University of Texas Health Science Center at San Antonio. The study found that 59.3% of the periradicu...

Microorganisms play an unequivocal role in infecting root canal system. Endodontic infections are different from the other oral infections in the fact that they occur in an environment which is closed to begin with since the root canal system is an enclosed one, surrounded by hard tissues all around [1,2]. Most of the diseases of dental pulp and periradicular tissues are associated with microor...

Vital pulp therapy (VPT) of permanent mature teeth is continuously ascertaining to be a more reliable endodontic treatment. The purpose of this case report was to describe successful VPT of a mature mandibular left first molar with concurrent hyperplastic pulpitis, internal root resorption and periradicular periodontitis in a 35-year-old male patient. After complete caries removal and access ca...

Periradicular surgery has become an established treatment option in endodontic surgery. The major objective of this surgery is to obtain periradicular tissue regeneration, including the formation of a new attachment apparatus, by exclusion of any potentially noxious agent within the physical confines of the affected root. However, in a substantial number of cases, the endodontic lesion has a co...

BACKGROUND AND AIM: Surgical endodontics may sometimes fail despite using root-end filling materials (REFMs). In this case report, a symptomatic right maxillary first premolar underwent periradicular surgery (PS) for replacing huge rate of amalgam with mineral trioxide aggregate (MTA).CASE REPORT: A thirty-year-old healthy woman attended with the chief complaint of recurrent swelling and absces...

abstract : inflammatory external root resorption (ierr) is a pathological phenomenon of microbial origin. this stu dy reports a case of external apical inflammatory root resorption of maxillary incisors associated with periradicular lesions in a 22 year old female, which was successfully treated by one-visit root canal therapy (rct). radiographic investigation revealed periapical radiolucencies...
