Objectives: The aim of this study was to evaluate the variability intensity values in cone beam computed tomography (CBCT) imaging compared with multislice Hounsfield units (MSCT HU) order assess reliability density assessments using CBCT images. Material and methods: A quality control phantom scanned an MSCT scanner five scanners. In one scanner, repeatedly same different positions. Images were analyzed registration a mathematical model. images used as reference. Results: Density profiles...
The study aim is to investigate the influence of scan field, mouth opening, voxel size, and segmentation threshold selections on quality three-dimensional (3D) surface models dental arches from cone beam computed tomography (CBCT). 3D 25 patients scanned with one image intensifier CBCT system (NewTom 3G, QR SLR, Verona, Italy) using three field sizes in open- closed-mouth positions were created at different size resolutions. Two observers assessed independently a five-point scale specified...
To investigate the effect of tube current-exposure time (mAs) reduction on clinical and technical image quality for different CBCT scanners, to determine preliminary minimally acceptable values mAs contrast-to-noise ratio (CNR) in CBCT.A polymethyl methacrylate (PMMA) phantom an anthropomorphic skull phantom, containing a human skeleton embedded polyurethane, were scanned using four devices, including seven exposure protocols. For all protocols, was varied within selectable range. Using PMMA...
To analyze the consumption frequency and factors associated with hookah usage. This cross-sectional study involved adults, users, residing in city of Curitiba. Hookah groups were contacted on social networking sites via an invitation that contained a link to questionnaire, which comprised 21 questions covering demographic socioeconomic characteristics, user profiles, use cigarettes alcohol, symptoms, perceptions risks use. The dependent variables low high frequency. Multivariate analysis was...
Objective The objective was to evaluate the early-stage immunoexpression of markers (COX-2, NF-kB, VEGFR-1 and apoptotic index) related inflammation, angiogenesis, cell survival in tongue dorsum epithelium mice exposed hookah smoke. Materials methods sample consisted Swiss (N = 20), female gender, aged 2 months, approximately 25g each, four groups (n 5) mice: group fresh air smoke for 7, 15, 30 days. Tongues were embedded paraffin. A tissue microarray constructed, immunohistochemistry...
Variations in the root canal anatomy of a maxillary first molar are often challenging to diagnose and treat; thus, clinicians must have thorough knowledge same. This case report highlights successful nonsurgical endodontic management with an unusual morphology. Three canals were prepared using Sequence Niti rotary instruments (MK Life) #25.06, irrigated 2,5% sodium hypochlorite solution. Root filling was performed single cone technique associated Bio-C Sealer cement 25.06 taper gutta-percha...
O objetivo deste estudo foi o de apresentar um relato caso clínico uma paciente com necessidade tratamento endodôntico no elemento 46, portador pulpite irreversível assintomática. Paciente 36 anos, gênero feminino, procurou atendimento em consultório particular, relatando dor ao morder. A radiografia revelou canais atrésicos e fratura coronária possível exposição pulpar. realizado limas especiais da C-Pilot Glide Path para se obter a patência, sistema mecanizado rotatório, Sequence Rotary...
Summary Variations in jaw bone neurovascularisation must be identified to decrease the potential risk for haemorrhages and neural disturbances during surgical procedures such as implant placement orthognatic surgeries. The aim of this study is characterise additional mental foramina (AMF) through cone beam computed tomography (CBCT) images, by describing their frequency, size, location direction associated bony canals, well assess corresponding ipsilateral contralateral (MF). CBCT images...
The purpose of this study was to evaluate and compare the efficacy a conventional digital radiographic method in diagnosing simulated external root resorption cavities.Human dry mandibles containing teeth were covered with bovine muscle slices order simulate soft tissues. Nine from each dental group investigated. Three periapical radiographs tooth taken an orthoradial, mesioradial distoradial aspect using film (Insight Kodak F-speed; Eastman Kodak, Rochester, NY) sensor (DRS Gnatus System;...
Abstract Objective To investigate the association between severity of periodontitis (exposure) and dyslipidemia (outcome). Methods This was a cross‐sectional study users public health services. Periodontitis defined using Center for Disease Prevention Control American Academy Periodontology criteria. Lipid evaluation used data on systemic biomarkers. Dyslipidemia diagnosis based Guidelines total cardiovascular risk World Health Organization. Weight, height, waist circumference, blood...
ObjectiveThe aim of this study was to compare the agreement between cone beam computed tomography (CBCT) and panoramic radiographs for initial orthodontic evaluation. This not meant test differences imaging modalities or indicate superiority one technique.Study DesignThirty-eight subjects with both CBCT images were retrospectively collected. Eight observers answered 14 observational questions. The observation repeated after 4 weeks.ResultsCBCT yielded better 2 observer groups (orthodontic...
Nowadays, technological advances are becoming more and important in forensic sciences. Yet autopsy is still one of the very traditional methods. This also applies for dentalautopsies, which visual, photographic radiological evidences collected. In this context, Virtual Autopsy appears as a helpful complementary tool dental medical cadaveric examination. Usinghigh-tech approaches, may provide, through images, an efficient accurate view on individual case. critical review aims to update...
OBJECTIVE: The aim of this study was to evaluate the effectiveness clinical criteria for diagnosis hyposalivation in hospitalized patients. MATERIAL AND METHODS: A carried out on 145 subjects (48 males; 97 females; aged 20 90 years). Each subject clinically examined, morning and afternoon, along 1 day. focused anamnesis allowed identifying symptoms hyposalivation, like xerostomia complaints (considered as a reference symptom), chewing difficulty, dysphagia increased frequency liquid intake....
