Developmental anomalies in tooth structure can involve dental enamel, dentin, pulp, cementum, or a combination of these tissues. While relatively precise typing of some of these anomalies is now possible using techniques in molecular biology, radiography remains important in the assessment of phenotypic manifestations and is often essential in treatment-planning for esthetics and function of de...
Introduction: Dentin Dysplasia is one of the rare hereditary diseases that the enamel is normal, but it also affects the dentin and the shape of the tooth pulp. Due to the low prevalence of this disease, a case of dentin dysplasia with the classical and atypical dentin dysplasia type 1 is presented. Case presentation:A 11-year-old girl with the mobility of lower central teeth that has severe ...
OBJECTIVES The purpose of the present study was to investigate the reliability of both periapical radiographs and orthopantomograms for exact detection of tooth root protrusion in the maxillary sinus by correlating the results with cone beam computed tomography. MATERIAL AND METHODS A database of 1400 patients scanned with cone beam computed tomography (CBCT) was searched for matching periapi...
OBJECTIVE To assess the diagnostic potential of 2 different cone-beam computerized tomography (CT) units and compare this with intraoral digital and conventional film in the detection of chemically created periapical lesions. STUDY DESIGN Periapical lesions were created chemically in 27 intact roots of 23 teeth (6 incisors, 4 canines, 6 premolars, and 7 molars). Cone-beam CT and digital and f...
INTRODUCTION The aim of this study was to compare the outcome of a root canal treatment with and without additional ultrasonic activation of the irrigant. METHODS Single-rooted teeth with radiographic evidence of periapical bone loss were randomly assigned to 2 treatment groups. In both groups syringe irrigation was performed, and in one group the irrigant was also activated by ultrasound. Te...
