o bjectives: correct determination of working length is an important step for suc- cess of endodontic therapy. conventional radiography has limitations in providing the accurate location of apical foramen. for this reason, electronic apex locators (eals) were developed to shorten the treatment time and decrease the radiation dose. the aim of this study was to evaluate the accuracy of root zx ea...

Several points remain unclear about the effects on the periodontal tissues during the time that an impulse on a tooth is transmitted to the apex of the root. In this study performed from the standpoint of oscillatory science, random vibration was applied to teeth in an attempt to use data from the tooth crown and the apex of the root in determining indirectly the kinetic properties of the perio...

Management of a tooth with open apex is a challenge to the dental practitioners. Evaluation of the periapical healing is required in such cases by radiographic techniques. The objective of this paper was to assess the healing of a periapical lesion in a non-vital tooth with open apex treated with mineral trioxide aggregate (MTA) obturation using cone beam computed tomography (CBCT). The endodon...

this case report describes treatment of a necrotic immature permanent mandibular first molar with pulpal necrosis in 9-year old female with spondyloepiphyseal dysplasia. the coronal half of the root canal was debrided with a file #30 to remove necrotic tissue, and irrigated with chlorhexidine 0.12%. bleeding was evoked to form an intracanal blood clot; the wound was then dressed with calcium hy...

Mucosal fenestration is a clinical condition where tooth root apices are visible in the oral cavity due to loss of overlying alveolar bone and mucosa. Mucosal fenestration mostly affect maxillary incisors. The present case series reports two cases where patient reported with complaint of unesthetic appearance because of exposed roots of maxillary anterior teeth which on radiographic examination...

Introduction: Dental autotransplantation is an economical and viable alternative for the replacement of teeth with closed apex. The use piezoelectric surgery a beneficial tool considered less invasive technique, ideal dental organs. Objective: To analyze literature on using 3D replicas donor teeth, as well prognosis treatment in immature apex complete apex, extraction tooth tissue regeneration ...

Cone beam computed tomography (CBCT) is a recent three-dimensional (3D) radiographic imaging modality used for the accurate diagnosis, management and follow-up of endodontic problems. In tooth with open apex and periapical lesion, the use of new obturation material such as white mineral trioxide aggregate (wMTA) facilitates faster and more predictable closure of root apex and periapical healing...

BACKGROUND This in vitro study was conducted to compare the accuracy of two digital image receptors in identifying the location of tip of a fine endodontic file and radiographic apex in mandibular posterior teeth. METHODS Fourteen human cadaver mandibles with retained molars were selected. These molars were prepared for access to the canals and an endodontic file #10 was introduced into the c...

OBJECTIVES The purpose of this study was to evaluate the proximity of the mandibular molar apex to the buccal bone surface in order to provide anatomic information for apical surgery. MATERIALS AND METHODS Cone-beam computed tomography (CBCT) images of 127 mandibular first molars and 153 mandibular second molars were analyzed from 160 patients' records. The distance was measured from the bucc...
