Diagnostic accuracy of panoramic radiography, stereo-scanography and cone beam CT for assessment of mandibular third molars before surgery.

Objective: To compare the diagnostic accuracy of panoramic imaging, stereo-scanography and cone beam computed tomography (CBCT) for assessment of mandibular third molars.

Material And Methods: One hundred and twelve patients (147 third molars) underwent radiographic examination by panoramic imaging, stereo-scanography and CBCT. Tooth angulation, root morphology, number of roots and relation to the mandibular canal were assessed.

Implications of caries diagnostic strategies for clinical management decisions.

Objectives: In clinical practice, a visual-tactile caries examination is frequently supplemented by bitewing radiography. This study evaluated strategies for combining visual-tactile and radiographic caries detection methods and determined their implications for clinical management decisions in a low-caries population.

Methods: Each of four examiners independently examined preselected contacting interproximal surfaces in 53 dental students aged 20-37 years using a visual-tactile examination and bitewing radiography.

Craniofacial morphology in patients with hypophosphatemic rickets: a cephalometric study focusing on differences between bone of cartilaginous and intramembranous origin.

Hypophosphatemic rickets (HR) are diseases characterized by deficient mineralization of bone due to abnormal renal wasting of phosphate. Deformation of bony structures of cartilaginous origin has been described as a major characteristic in patients with HR, but little is known about the impact on bony structures of intramembranous origin. The aim of the present study was to describe the osseous morphology of the craniofacial structures in patients with HR compared to healthy controls, and to investigate the impact of different bone origin on the osseous morphology.

Influence of cross-sectional temporomandibular joint tomography on diagnosis and management decisions of patients with temporomandibular joint disorders.

Aim: To assess whether changes in diagnoses and management of temporomandibular joint disorder (TMJD) patients are influenced by radiographic findings and if there is an association between specific radiologic alterations and management strategy changes.

Methods: A total of 204 patients with TMJ symptoms were examined using the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Diagnoses and management were first decided without the aid of radiographs.

Phenotype presentation of hypophosphatemic rickets in adults.

Hypophosphatemic rickets (HR) is a group of rare disorders caused by excessive renal phosphate wasting. The purpose of this cross-sectional study of 38 HR patients was to characterize the phenotype of adult HR patients. Moreover, skeletal and endodontic severity scores were defined to assess possible gender differences in disease severity in patients with genetically verified X-linked HR.

Hypocalcified type of amelogenesis imperfecta in a large family: clinical, radiographic, and histological findings, associated dento-facial anomalies, and resulting treatment load.

Objective: The purpose of this study was to report on the clinical, radiographic, and histological dental findings and the resulting treatment load in a five-generation family with amelogenesis imperfecta (AI).

Material And Methods: Thirteen affected and 15 unaffected individuals were examined clinically and radiographically. In addition, four exfoliated deciduous teeth were examined by scanning electron microscopy and microradiography.

Association between temporomandibular joint symptoms, signs, and clinical diagnosis using the RDC/TMD and radiographic findings in temporomandibular joint tomograms.

Aim: To identify associations between clinical symptoms of temporomandibular joint disorders and radiographic findings.

Methods: Two hundred four adult patients (156 women, 48 men, mean age 40 years) with temporomandibular joint (TMJ) pain/sounds or changes in mandibular motion were examined according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Bilateral sagittal corrected TMJ tomograms in closed and open positions were assessed for the presence of flattening, erosion, osteophytes, and sclerosis in the joint components and the range of mandibular motion.

Amelogenesis imperfecta - a systematic literature review of associated dental and oro-facial abnormalities and their impact on patients.

Objective: Amelogenesis imperfecta (AI) is a disease primarily affecting amelogenesis, but other aberrations have been reported. The purposes of this review were: (1) to identify other anomalies associated with AI, and (2) to describe the impact of the disease and its associated conditions on the oral health-related quality of life of patients, and the economic consequences.

Material And Methods: A literature search was conducted in the following databases: PubMed, EMBASE, Bibliotek.

Osseous changes and condyle position in TMJ tomograms: impact of RDC/TMD clinical diagnoses on agreement between expected and actual findings.

Objective: The objective of this study was to evaluate the impact of clinical TMJ diagnosis, gender, and age on the agreement between expected and actual radiographic findings.

Study Design: A total of 204 patients with TMJ symptoms were examined using the Research Diagnostic Criteria (RDC/TMD). Expected radiographic findings were recorded.

Mandibular third molar removal: risk indicators for extended operation time, postoperative pain, and complications.

Objectives: The aim of this study was to identify risk indicators for extended operation time and postoperative complications after removal of mandibular third molars.

Study Design: There were 388 molars included in the study. The teeth were removed using the buccal approach under local anesthesia.

Relationship between histological and radiographic caries lesion depth measured in images from four digital radiography systems.

The aim of this study was to compare the accuracy of approximal caries lesion depth measurements in radiographs from four digital systems. Two CCD-based sensors, Dixi (Planmeca) and Sidexis (Sirona), and two phosphor plate systems, Digora (Soredex) and DenOptix (Gendex), were used to record radiographs of 177 extracted human teeth. Sixty-four radiographically visible lesions were selected and measured by 4 observers in the digital radiographs and in digital photographs of histological sections of the teeth.

Influence of number of surfaces and observers on statistical power in a multiobserver ROC radiographic caries detection study.

The aim of the study was to evaluate the influence of the number of surfaces (N(SURF)) and the number of observers (N(OBS)) on the statistical power of a study comparing the diagnostic accuracies of radiographic systems used for approximal caries lesion detection. A data set consisting of 338 surfaces examined by 10 independent observers using four radiographic systems was available. The presence of a caries lesion was assessed from a 5-point confidence scale.

Diagnostic outcome of methods frequently used for caries validation. A comparison of clinical examination, radiography and histology following hemisectioning and serial tooth sectioning.

The aim of this study was to compare the caries diagnostic outcome of four methods frequently used as validation for dental caries. The diagnostic outcome of clinical examination (CL), radiography (RA), and histology after serial tooth sectioning (HI-serial) on 373 approximal and 158 occlusal surfaces was compared, and furthermore histology after hemi- (HI-hemi) and serial sectioning on another 113 approximal and 53 occlusal surfaces was compared. Two thresholds for each method (CL: (1) sound vs.

Accuracy of computer-automated caries detection in digital radiographs compared with human observers.

The aim of this study was to compare diagnostic accuracy of a caries detection program with that of human observers. A total of 190 extracted teeth were radiographed with two Trophy RVG (RadioVisioGraphy) digital sensor systems. Four observers scored the approximal surfaces in all images on a disease severity scale.
