This case report describes the non - surgical management of a large periapical lesion using Metapex as intracanal dressing and root canal therapy. Periapical lesions usually develop in non-vital teeth result chronic aggression by pathogenic microorganisms into which may appear radiolucent radiographs. Treatment such varies from non-surgical means depending on individual. In era minimally invasi...

OBJECTIVE To investigate the influence of radiographic film and tube positioning, the presence and the size of brackets on in vitro measurements of proximal enamel thickness of mandibular incisors on periapical radiographs aimed to aid planning of interproximal enamel reduction procedures in orthodontics. MATERIALS AND METHODS Eighty human mandibular incisors were assigned to sets of four and...

The present study aimed to assess the prevalence of apical periodontitis (AP) in an urban Brazilian population according to gender, age group and tooth type. Data were collected from clinical files containing the medical and dental histories and periapical radiographs of 1,126 patients treated at the School of Dentistry at Universidade do Estado do Rio de Janeiro between March 2000 and December...

Introduction Dental implant placement in the region of the mental foramen has been known to cause neurosensory deficit due to nerve injury.1-4 The identification and preservation of the anterior loop (AL) of the mental nerve is an important means of avoiding such neurosensory deficit.5-7 There is a general consensus that plain film radiographs are inadequate for the accurate identification of t...

Objectives. To compare the ability of endodontists to determine the size of apical pathological lesions and select the most appropriate choice of treatment based on lesions' projected image characteristics using 2 D and 3 D images. Study Design. Twenty-four subjects were selected. Radiographic examination of symptomatic study teeth with an intraoral periapical radiograph revealed periapical les...

HEIDI KOHLTFARBER, DDS: A Comparison of 2D versus 3D Radiography in the Diagnosis and Treatment Planning of Root Canal Treated Teeth with Periapical Lesions (Under the direction of Donald Tyndall) Objectives: The aims of the study were to assess diagnostic efficacy in lesion detection, evaluate the effect of cone beam CT on treatment planning and clinician confidence. Methods: Forty digital per...

OBJECTIVE To explore the relationship between cone beam computed tomography (CBCT) measurements and direct measurements during the surgery to correct intrabony defects. METHODS Forty-four patients with 44 intrabony defects who finished initial periodontal therapy and were considered for periodontal surgery were recruited. Digital periapical radiography and CBCT was performed before the surger...

PURPOSE The aim of this in vitro study was to determine the sensitivity and specificity of cone-beam computed tomography (CBCT) and digital periapical radiography in the detection of mesial root perforations of mandibular molars. MATERIALS AND METHODS In this in vitro study, 48 mandibular molars were divided into 4 groups. First, the mesial canals of all the 48 teeth were endodontically prepa...

OBJECTIVE To compare intraoral periapical radiography with 3D images for the diagnosis of periapical pathology. STUDY DESIGN Maxillary molars and premolars and mandibular molars with endodontic problems and examined with periapical radiographs and a 3D technique (3D Accuitomo) were retrospectively selected and evaluated by 3 oral radiologists. Numbers of roots and root canals, presence and lo...

PURPOSE The purpose of this study was to evaluate a new technique for localizing impacted mesiodens using its horizontal magnification ratio on panoramic radiographs. MATERIALS AND METHODS Location-magnification equation of a panoramic equipment was obtained from horizontal magnification ratio of a metal ball which was located variable positions from the center of image layer at interval of 2...
