PURPOSE The aim of this study was to determine the frequencies of apical periodontitis and endodontic treatment in a Turkish population using a retrospective analysis of orthopantomograms. MATERIALS AND METHODS The sample consisted of orthopantomographs of 250 subjects who had been referred to our clinic for an initial visit between the years of 2013 and 2014. The periapical status of all tee...

Apical periodontitis is a relatively frequently encountered disease in clinical dentistry; however, its pathogenesis and etiology are not easily elucidated. Therefore, it is not always cured, even when carefully following the highest standards of treatment and intractable apical periodontitis may occur. In addition, in long-term root canal treatment of difficult cases with intractable pain, the...

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 ...

objectives: this study sought to assess the diagnostic accuracy of cone beam computed tomography (cbct) with different voxel sizes and intraoral digital radiography with photostimulable phosphor (psp) plate for detection of periapical (pa) bone lesions. materials and methods: in this ex vivo diagnostic study, one-millimeter defects were created in the alveolar sockets of 15 bone blocks, each wi...

introduction: this cross-sectional survey determined the dental prevalence of apical periodontitis (ap) in selected iranian population, and evaluated the influence of the quality of root canal treatment (rct) and their coronal restorations (cr) on the periapical status. materials and methods: a total of 1064 panoramic radiographies were evaluated by two observers during 2009. the quality of rct...

AIM To re-examine a population after 20 years and evaluate changes in prevalence of endodontic treatment and apical periodontitis, as well as the technical quality of root fillings. METHODOLOGY One hundred and fifteen out of an original 200 patients living in the northern part of Sweden were re-examined with a full mouth radiographic survey after 20 years. Frequencies of root canal treated te...

AIM To compare the apical negative pressure irrigation (ANP) with conventional irrigation in the teeth of immature dogs with apical periodontitis. METHODS Fifty-two immature pre-molar root canals were randomly assigned into 4 groups: ANP (n=15); conventional irrigation (n=17); healthy teeth (control) (n = 10); and teeth with untreated apical periodontitis (control) (n=10). After induction of ...

paresthesia is a burning or prickling sensation or partial numbness, resulting from neural injury. the symptoms can vary from mild neurosensory dysfunction to total loss of sensation in the innervated area. only a few cases have described apical periodontitis to be the etiological factor of impaired sensation in the area innervated by the inferior alveolar and mental nerves. the aim of the pres...

The regenerative endodontic treatment (RET) of human immature permanent tooth with apical periodontitis using platelet-rich fibrin (PRF) has shown successful results in incisor. The purpose of this case series is to report four cases of the management of dens evaginatus in immature mandibular second premolars with apical periodontitis using PRF in regenerative endodontics. Four dens evaginatus ...

Apical periodontitis (AP) is a chronic infection of endodontic origin accompanied with bone destruction around the apical region. Semaphorin3A (Sema3A) and neuropilin-1 (Nrp1) are regarded as a pair of immune regulators in bone metabolism. In this study, we firstly investigated the expression pattern of Sema3A/Nrp1 in apical periodontitis and its correlation with bone destruction. Using rat ani...
