The unique morphology of dilacerated and S-shaped root canals often poses utmost challenges in their endodontic management. Dilaceration is defined as developmental anomaly which there has been an abrupt change the axial inclination between crown a tooth. Periapical radiographs CBCT are most appropriate way to diagnose presence dilacerations. Also, clinician required have insight tooth related ...

OBJECTIVES The aim of the present study was to compare the accuracy of intraoral digital periapical radiography and cone beam computed tomography in the detection of periapical radiolucencies in endodontically treated teeth. MATERIAL AND METHODS Radiographic images (cone beam computed tomography [CBCT] scans and digital periapical radiography [PR] images) from 60 patients, achieved from Septe...

OBJECTIVES The purpose of this study was to examine radiographically changes in the periapical status and compare the clinical status of teeth with a vital pulp and root-filled teeth restored with crowns and bridge retainers during 25 years. METHODS During 1967/68, 114 patients received prosthodontic treatment by senior dental students at the Oslo Dental Faculty. In all, 291 teeth with a vita...

Sickle cell anemia may expand marrow spaces in the jaws. Fourier analysis is well-suited to the analysis of trabecular spacing in radiographs. We hypothesize that individuals with sickle cell anemia demonstrate increased intertrabecular spacing. Periapical radiographs of 18 African Americans with sickle cell disease and 18 controls were examined by one-dimensional discrete Fourier analyses in b...

OBJECTIVE To determine the prevalence and distribution of dilaceration in all tooth groups by using radiographs. STUDY DESIGN The sample included 953 periapical intraoral radiographs and 488 panoramic radiographs from different caucasian patients. The ages of the patients ranged from 18-65 years. Dilaceration of the root was detected by measuring the degree of deviation from the long axis (de...

AIM To radiographically compare periapical repair of roots with infected root canals obturated in one-step or with calcium hydroxide (Ca(OH)2) intracanal medication in two steps. METHODOLOGY Standardized preoperative periapical radiographs were taken of 72 roots of vital dogs' teeth. All roots were then aseptically instrumented to ISO size 45. As negative controls, 12 roots were aseptically o...

A 38-year-old female presented with pain and a fistula above her left central incisor, tooth No. 9. The medical history was unremarkable, and the patient appeared to be in good overall health. The patient was not taking any medications. Periapical radiographs revealed advanced external resorption associated with tooth No. 9 (Figure 1). The tooth had been re-implanted after trauma caused its rem...
