OBJECTIVE The purpose of this study was to evaluate the pulp healing process and the dentin-cementum complex in 51 endodontically treated human teeth after long observation periods and to correlate histologic observations with conventional periapical radiographic findings. STUDY DESIGN Specimens were obtained from the extraction of 77 treated teeth, which were deemed to be unrestorable, with ...

INTRODUCTION Bacterial infection of tooth pulp can progress into periapical diseases. Root canal treatment has been established as the best treatment. In cases of failure, nonsurgical retreatment of teeth is preferred to surgical procedure and extraction. MATERIALS AND METHODS In this historical cohort study, 104 permanent teeth with apical lesion were treated during 2002-2008. All teeth show...

Objective. The purpose of this study was to investigate the clinical and radiographic success of teeth restored with posts. Material and method. Periapical radiographs of 101 teeth with posts taken from 75 patients were examined. Posts were evaluated in terms of their position, remaining amount of gutta-percha, lengths and diameters, quality of root filling and periapical health. Furthermore, c...

Periapical radiography is a routine radiographic procedure performed by dentists on daily basis. It can be taken with two techniques, the paralleling technique (P tech) and bisecting angle (B tech). This systematic review aimed to identify relevant literature, compare use of P B techs across various dental specialties, determine most appropriate used for different purposes in taking periapical ...

Methods: Periapical samples were collected from 18 acute apical abscess specimens and 6 control samples. The apical area of each study tooth was examined in periapical radiographs obtained using a long cone paralleling technique. The study included only single-rooted teeth that had carious lesions, necrotic pulps, and radiographic evidence of periradicular bone loss. No apparent communication f...

Apexification with calcium hydroxide is associated with certain difficulties, such as longer treatment time, risk of tooth fracture and incomplete calcification of apical bridge. Mineral trioxide aggregate (MTA) is an alternative material that can be used for apexification of open apices due to its biocompatibility, non-mutagenicity, non-neurotoxicity, regenerative abilities, and good sealing p...

This article describes and discusses a method to determine root curvature radius by using cone-beam computed tomography (CBCT). The severity of root canal curvature is essential to select instrument and instrumentation technique. The diagnosis and planning of root canal treatment have traditionally been made based on periapical radiography. However, the higher accuracy of CBCT images to identif...

A 19-year-old female patient reported to the Department of Conservative Dentistry and Endodontics, with the chief complaint of food lodgment in her upper right and lower left back tooth. There was associated history of mild pain while bitting. Her medical and family history was noncontributory. Intra oral examination revealed a deep carious lesion with respect to the mandibular right second pre...

Radiologic supportive examinations are still the primary choice in helping dentists establish a diagnosis and treatment plan. Radiography is basis of diagnostic imaging dentistry because main focus this field hard tissue teeth bone supporting teeth. Dental radiographic examination an that supports establishment diagnosis, making prognosis, planning, to evaluate results has been carried out on p...
