Introduction & Objective: Diagnosis of periodontal osseous lesions is very important in deter-mining prognosis, treatment plan and maintenance in the long term. This diagnosis can be achieved by using radiography. The aim of this study is to compare accuracy of E speed films, bitewing PSP, panoramic PSP and CCD for identifying the extent of destruction of alveolar bone in chronic periodontiti...
PURPOSE The aim of this study was to compare the diagnostic accuracy of cone-beam computed tomography (CBCT) images and bitewing images in detection of secondary caries. MATERIALS AND METHODS One hundred and twenty proximal slots of Class II cavities were randomly prepared on human premolar and molar teeth, and restored with amalgam (n=60) and composite resin (n=60). Then, artificial secondar...
Introduction: The height of the alveolar bone, is normally maintained by equilibrium between bone formation and bone resorption, but in periodontal disease more destruction or lack of bone formation will reduce the alveolar bone height. However the radiography is important in diagnosis, treatment plan and detection of quality and quantity of the alveolar bone although the type of radiography is...
BACKGROUND The accurate detection of approximal caries is generally difficult. The aim of this study was to assess the ability of the pen-type laser fluorescence device (LF pen) to detect approximal carious lesions in comparison to bitewing radiographs (BW). METHODS Three hundred forty-one tooth surfaces were diagnosed in 20 patients with an average age of 26.70 (±2.82) years. Each test tooth...
Dental Caries are one of the most prevalent chronic diseases around globe. Detecting carious lesions is a challenging task. Conventional computer aided diagnosis and detection methods in past have heavily relied on visual inspection teeth. These only effective large clearly visible caries affected been limited performance due to complex characteristics dental images, which consist hidden or ina...
The aim of the present study was to investigate the reasons for the persistence of primary teeth and also use panoramic radiography to determine the characteristics of persistence teeth. Four-hundred and twenty-six panoramic radiographies, which diagnosed one or more retained primary teeth, were selected from 100,577 panoramic radiographic image files from nine clinics and six different cities ...
Background and purpose: Dental caries are highly prevalent and their exact detection at initial stages is necessary. The laser-based DIAGNOdent device is used to detect these caries. The aim of this study was to assess the level of agreement between visual observation, bitewing radiographs, and DIAGNOdent system in detection of proximal caries in clinical applications. Materials and methods: I...
Bitewing radiographs have been one of the dentist’s chief diagnostic tools in the dental clinic. They increase detection of interproximal caries approximately two-fold when compared to clinical examination alone. To a much lesser extent, the bitewing may be used to diagnose occlusal caries. The dentist examining a bitewing radiograph will pay attention to the alveolar crests thus assessing peri...
