The aim of this study was to determine the diagnostic accuracy cone beam computed tomography (CBCT) in detection approximal and occlusal noncavitated carious lesions.A total 135 extracted human posterior teeth were used. They radiographed using following: conventional film (Kodak Insight), a digital system (PSP plates Digora Optime, Soredex), CBCT (NewTom 3G, Quantitative Radiology). All images assessed by two independent observers twice. Receiver operating characteristic analysis (Az)...

Objective . The aim of the study based on CT images was to assess age-related changes in maxillary sinus diameters relation facial skeleton. Materials and Methods retrospective analysis head 170 patients aged 0–18 years (85 females 85 males) performed. Specific orientation points (zy, zm, pr, ns, n, P) were identified every patient following distances measured: zy-zy, maximum width; zm-zm, midfacial n-pr, upper height; ns-pr, alveolar ns-P, distance not indicated craniometry. Results sinuses...

The anthropometric measurements of the skeletonized skull are crucial in investigation human remains, mostly for personal identification. images used if superimposition or approximation facial appearance is to be performed. aim study was compare accuracy skulls with corresponding their 3D reconstructions obtained by CT scanning.Ten and digital were measured according standard procedures. results compared statistical analysis performed.The revealed that reconstruction absolutely reliable any...

Objectives: The aim of this CBCT investigation on the detection caries was to assess influence artefacts produced by presence amalgam fillings located in vicinity. Methods: 102 non-cavitated pre-molar and molar teeth were placed blocks silicone with approximal contacts consisting 3 sound or carious 1 mesial–occlusal–distal amalgam-filled tooth in-between. Radiographs all recorded using system (NewTom™ 3G; QR Srl, Verona, Italy; field view, 9 inches). Data from unit reconstructed sectioned...

The aim of this study was to evaluate the accuracy cone beam computed tomography (CBCT) in detection noncavitated occlusal caries lesions and compare with that observed conventional radiographs. 135 human teeth, 67 premolars 68 molars macroscopically intact surfaces, were examined by two independent observers using CBCT system: NewTom 3G (Quantitative Radiology) intraoral film (Kodak Insight). true lesion diagnosis established histological examination. methods compared means sensitivity,...

Background: The study aimed to evaluate radiomorphometric indices derived from panoramic X-rays and selected blood markers of bone turnover neutrophil extracellular traps, with a view identifying hemophilic patients at risk developing osteoporosis. Methods: consisted 50 adult men hemophilia A B (mild, moderate, severe). control group 25 healthy men. In both groups, samples were collected determine concentrations citrullinated histone H3 (CH3) osteocalcin (BGLAP) ELISA tests, obtained. Images...

We described an 11-year follow-up of a patient with non-syndrome multiple supernumerary teeth who had one extra tooth in the maxilla and four additional premolars mandible. Together distal migration second lower right premolar to ramus mandible that also occurred, it comprises unique combination conditions were not previously presented literature. showed significance routine X-rays cases hyperdontia since may develop later than expected experience any symptoms.

The inferior alveolar canal (IAC) is a fundamental mandibular structure. It important to conduct precise pre-surgical evaluation of the IAC prevent complications. Recently, use artificial intelligence (AI) has demonstrated potential as valuable tool for dentists, particularly in field oral and maxillofacial radiology.

Objectives . Fractal analysis of the radiographic pattern bone has been used to evaluate its quantitative properties. However, relation between initial implant stability and quality remains unclear. The objective this study was RFA values in fractal dimension where inserted. Material Methods A total 50 two-stage dental implants were placed maxilla mandible 32 patients. After placement, an quotient (ISQ) measured two perpendicular planes. On intraoral digital periapical radiographs, three...

This study aimed to assess the asymmetry of lower face and motor dysfunction masticatory system resulting from unilateral or asymmetrical bilateral temporomandibular joint (TMJ) involvement in juvenile idiopathic arthritis (JIA) patients. The consisted clinical examination cone beam computed tomography (CBCT) TMJs. Statistical analysis showed correlations between several factors: facial mandibular lateral deviation; direction deviation degree radiological deformities TMJs; child’s age at...

The paper addresses the use of dental age assessment methods based on radiographs in medico-legal practice. Different cases practical application are presented including identification human remains, a living person and one archaeological case.The study material consisted involving performed Department Forensic Medicine, Poznan University Medical Sciences Poznan. Depending preliminary age, Liversidge or Kvaal et al. were applied. Dental was estimated basis available pantomograms. In case...

Two cases of Sporadic Burkitt's lymphoma in children aged 11 and 8 years with primary symptoms the oral cavity are reported. The first disease appeared were initially misdiagnosed as an inflammatory condition one case incidental findings not associated reason for visiting dentist's office second case. Biopsies lesions revealed actual cause observed changes contributed to prompt initiation polychemotherapy treatment. A review current literature presents known Lymphoma available diagnostic...

Purpose:The main purpose of this study was to assess the oral health status patients receiving two different chemotherapy regimens (cisplatin/etoposide vs cisplatin/vinorelbine) for non small cell lung cancer .We analyzed local and general factors which may influence prevalence intensity mucositis in course chemotherapy.Methods: Patients were examined before, after, one cycle chemotherapy.The examination carried out with use a dental mirror, probe head light.For evaluation common...

Abstract This paper presents the case of a cadaver buried in pine grove, loamy soil at depth about 1.8 m. The is quite interesting due to fact that one hand victim was bare and other clad latex glove. In laboratory, severed hands were gently washed with water. left palm exhibited signs advanced decomposition. ridges visible only on thumb. gloved found be much better condition. There saponification palm. Ridges both all fingers visible. right hand, prints, thumb successfully matched against...

The paper presents a method of the determining mandibular cortical width on dental panoramic radiographs. Cortical lower border mandible may potentially be associated with recognition osteoporosis in postmenopausal women. An algorithm to perform semiautomatic measurement given region interest was developed. is based separate extraction and upper boundaries bone. Results performed 34 radiographs healthy osteoporotic individuals are presented, together automatic measurements particular...
