ObjectiveTo evaluate the influence of binarization methods (BnMs) on fractal dimension (FD) alveolar bone in digital radiographic images.Study DesignFive identical periapical radiographs were obtained from each 20 anatomical regions. Using ImageJ/Fiji software, a standardized region interest was positioned trabecular all radiographs, 14 BnMs independently applied, and FD calculated. The Friedma...

BACKGROUND The variation in mandibular molars' anatomy is not as rare as it might appear to be. Depending on the location of the additional root found in a mandibular molar, it may be referred to as either radix entomolaris (RE) or radix paramolaris (RP). The aim of the study was to present radiographic appearance of RE and RP and indicate the clinical implications of its presence. MATERIALS ...

PURPOSE This study employed a posteriori registration and subtraction of radiographic images to quantify the apical root resorption in maxillary permanent central incisors after orthodontic treatment, and assessed whether the external apical root resorption (EARR) was related to a range of parameters involved in the treatment. MATERIALS AND METHODS A sample of 79 patients (mean age, 13.5±2.2 ...

Different locations and healing patterns of horizontal root fractures bear different prognoses. Conventional periapical radiographs have been routinely used for the evaluation of the locations and healing of horizontal root fractures, with the limitation of presenting two-dimensional images. The three-dimensional imaging technology, cone-beam computed tomography (CBCT), has recently gained inte...

AIM Pulp stones are discrete calcified bodies found in the dental pulp. Sialolithasis is the most common salivary gland disease. The aim of the present study was to determine the relationship between the pulp stones and salivary gland stones. MATERIAL AND METHODS 196 patients were randomly selected from the out patient department for the study. The periapical radiographs for all patients were...

The only sign of chronic apical periodontitis is periapical lesions that are seen in radiographs. Lesions are visible when the inflammation reaches cortical plates. Lesions located in cancellous bone, cannot be easily seen in radiography. Developing computerized technology in radiography, which has numerous advantages and its show up devices in the market, encourage the clinicians to take advan...

OBJECTIVE The aim of this study was to evaluate whether the gap between the post restoration and the remaining root canal filling had an impact on the periapical health of endodontically treated teeth in a Turkish subpopulation. STUDY DESIGN Digital panoramic radiographs, evaluated for this cross-sectional study, were randomly selected from files of patients who attended to Yeditepe Universit...

Mucosal antral cysts(MACs) appear as dome-shaped soft-tissue opacities and have prevalences of between 1.6% and 8.7% on otherwise normal panoramic radiographs. The aim of this survey was to define the prevalence in the inner-city population in London. A 14% prevalence for MACs was observed in the panoramic radiographs of 1000 consecutive patients attending King's College Hospital dental casualt...

A new staging system for osteoradionecrosis of the mandible has been retrospectively applied to a group of 31 patients. In this system clinicoradiographic signs and symptoms are incorporated in a simplified manner. For imaging purposes the use of plain radiographs such as periapical films and panoramic radiographs is recommended, mainly because of their readily availability. The presented stagi...

PURPOSE The purpose of the study was to assess the contribution of a lateral extraoral radiograph for diagnosing the relation between the root of intruded maxillary primary incisors and their permanent successors. METHODS Three pediatric dentists examined intruded primary teeth 0-7 days after injury. The relations between the primary and permanent teeth were assessed in three separate steps: ...
