The torus palatinus is a unilocular or multilocular exostosis that occurs in the midline of the hard palate. It is considered a common clinical finding. Magnetic resonance imaging (MRI) is not commonly used in dentistry and descriptions of the torus by this imaging method are therefore rare in the literature. This case study reports on a female patient referred to the dentist to elucidate a bone enlargement detected by MRI, which was requested by the physician who accompanied the patient for migraine treatment...

OBJECTIVE: The aim of this study was to present an atypical case of a C-shaped root canal that was present in the vestibular root of a permanent maxillary second molar using PreXion 3-D cone-beam computed tomography (CBCT) as a diagnostic device. MATERIALS AND METHODS: A 50-year-old female patient was referred for routine examination to a private diagnostic imaging clinic in Recife-Pernambuco. During the physical examination, the presence of an unusual C-shaped anatomy in the vestibular canal with a mesiodistal interconnection that extended from the apical to the cervical third was detected in axial slices acquired with a PreXion 3-D scanner...

Currently, imaging techniques such as Computed Tomography with three-dimensional reconstruction (3D) and Magnetic Resonances are being routinely used in pre-surgical planning in all fields of medicine. Nowadays, virtual three-dimensional images, commonly displayed on two-dimensional surfaces, such as the computer screen, can be used to produce rapidly prototyped models, with excellent dimensional accuracy and fine reproduction of anatomical structures, providing professionals with the ability to use the biomodel in planning and simulating medical and dental procedures (oral and maxillofacial surgery, making individualized facial implants and prostheses, measurements and previous adaptations of prefabricated fixation plates), thus contributing to considerable reductions in surgical time and consequently the duration of anesthesia, minimizing infection risks and reducing hospital costs...

OBJECTIVES: The purpose of this study was to evaluate and compare lightness (L), chroma (C) and hue (h), green-red (a) and blue-yellow (b) character of the color of maxillary right central incisors in different light conditions and light sources. MATERIALS AND METHODS: Two examiners who were well trained in digital color evaluation participated in the research. Intraclass correlation coefficients (ICCs) were used to analyze intra- and interobserver reliability. The LCh and L*a*b* values were determined at 08...

BACKGROUND: The purpose of this study was to compare the adaptation of fiber reinforced composite post system and cast post-and-core. METHODS: 17 extracted human permanent maxillary central incisors were endodontically treated following the standard protocol. 17 fiber reinforced composite post had been fabricated and adapted to the prepared parallel root canals. A light body poly vinyl siloxane (EXAMIX NDS, Japan) impression material was inserted into the root canals followed by the post...

OBJECTIVES: To investigate the long-term development of the post-cure degree of conversion (DC) for two flowable bulk-fill composites. MATERIALS AND METHODS: Tetric EvoFlow Bulk Fill (TEFBF) and SDR were chosen due to their distinct compositional modifications that enable the decrease of translucency during polymerization and lower polymerization rate, respectively. DC was assessed using FT-Raman spectroscopy at the post-cure times of 0 h, 24 h, 7 d and 30 d. The post-cure behavior was analyzed by a mixed model ANOVA and partial eta-squared statistics...

The application of the Glass Ionomer Cements in clinical dentistry is recommended due to properties such as fluoride release, chemical adhesion to tooth, negligible setting shrinkage, and coefficient of thermal expansion close to tooth, low creep, and good color stability. However, the cement is vulnerable to early exposure to moisture due to slow setting characteristics. The uses of external energy such as ultrasound and radiant heat (Thermo-curing) have been reported to provide acceleration of the setting chemistry and enhance physical properties...

Erythema Multiforme, (EM) is an uncommon, acute inflammatory disease of the skin and mucous membranes characterized by ulcerations caused by hypersensitivity to drugs, microbial agents or other allergens. An EM outbreak can result in more severe forms of EM involving the skin, and there are several types of EM manifestations. A hemorrhagic crust on the lip is a pathognomonic sign of this disease. Target lesions may or may not be present in EM cases. When target lesions are not present on the skin, it is very difficult to make a differential diagnosis of EM...

The treatment of patients with oral cancer is complex: a multidisciplinary approach needs to be taken and maxillofacial and oral surgeons, an oncologist, a prosthodontist should be included, and a psychologist is often needed. This case report describes the prosthetic rehabilitation of a patient after surgical removal of oral cancer with obturator prosthesis. Resection cavity was located in central part of the hard palate and the condition belonged to Aramany class 3 maxillary defects. The two-step impression technique of denture bearing area was used and the resection of cavity was performed...

Zygomatic implants have been used for rehabilitation of the edentulous atrophic maxilla as an alternative to bone grafting for almost two decades resulting in satisfactory clinical outcomes. However, the patients with edentulous atrophic maxilla treated using this technique may present serious complications that could put the prosthetic restoration at risk. Four cases are reported in this paper, one case with a cutaneous fistula in the left zygomatic-orbital area caused by aseptic necrosis at the apical part of the implant, which was treated with the surgical removal of this part, a second case with loss of the right zygomatic implant due to failure of osseointegration and two cases of periimplantitis that resulted in partial and complete removal of the implant, respectively...

OBJECTIVE: Apical deviations are important factors in endodontic therapy, since they can cause the treatment failure. The aim of the present study was to determine the centering capacity of ProTaper Universal™, Twisted File™ and Revo-S(®) rotary systems using cone beam computed tomography analysis before and after the instrumentation of root canals. MATERIALS AND METHODS: Thirty mesiobuccal roots from human lower first molars were divided into three groups of ten: Group 1 - ProTaper Universal™ Rotary System; Group 2 - Twisted File™ Rotary System; and Group 3 - Revo-S(®) Rotary System...

AIM: The purpose of this study was to compare near visual acuity of dentists without optical aids (VSC) with near visual acuity of those using the Galilean telescope system (VGA2) with magnification of x 2.5, and the distance of 350 mm in simulated clinical conditions. METHODS: The study included 46 dentists (visual acuity 1.0 without correction). A visual acuity testing was carried out using a miniaturized Snellen visual acuity chart which was placed in the cavity of molar teeth mounted in a phantom head in simulated clinical conditions...

OBJECTIVES: To assess the prevalence of images suggestive of calcified carotid artery atheromas (ISCCAA) in panoramic radiographs of patients under dental treatment. MATERIALS AND METHODS: The sample consisted of 8.338 panoramic radiographs from female (n=5.049) and male (n=3.289) patients under dental treatment between 4 and 94 years of age. The panoramic radiographs were evaluated searching for ISCCAA. The obtained findings were statistically associated with sex and age...

The purpose of this study was to evaluate dimensions of adult human maxillary sinuses on panoramic radiographs and their possible application on the sex determination for forensic purposes. The sample comprised 64 database panoramic radiographs from individuals aged 20 years or older (32 male and 32 female subjects), with complete permanent dentition (or absence of third molars). One examiner measured the width and height of the right and left maxillary sinuses using the software Image J 1.47v (National Institutes of Health, Bethesda, USA)...

PURPOSE: Health care studies are usually considered to be complex, demanding and time consuming. The right motivation toward choosing a career in the health field is of utmost importance for the successful completion of studies. The aim of this study was to gain insight into the factors motivating students at the School of Dental Medicine University of Zagreb, Croatia and, also, to examine their career perceptions. MATERIAL AND METHODS: Based on specific questions from available literature, a questionnaire was designed and a total of 270 questionnaires were distributed to the first year students during 2013, 2014 and 2015...
