The purpose of this study was to evaluate morphological characteristics teeth with hypercementosis that are relevant endodontic practice. Twenty-eight extracted had their root apexes analyzed by scanning electron microscopy (SEM). were divided according tooth groups and type hypercementosis. following aspects examined under SEM: the contour regularity surface; presence resorption; number apical foramina, diameter main foramen. progression club shape directly associated foramina foramen...
Abstract Aim To investigate the effects of liver fibrosis (LF) on pro‐inflammatory mediators and periapical bone resorption apical periodontitis (AP) in rats. Methodology Forty male Wistar rats were distributed into four groups: C – control, AP with AP, LF LF, + LF. was induced by carbon tetrachloride administration for 8 weeks surgical bile duct ligation 4 weeks; teeth dental pulp exposure to oral environment 30 days. Jaws livers removed after euthanasia. Haematoxylin Eosin (H&E)...
OBJECTIVE: The aim of this study was to compare two methodologies used in the evaluation tissue response root-end filling materials rats. MATERIAL AND METHODS: Forty rats were divided into 4 groups: Groups I and II (control groups), empty polyethylene tubes implanted extraction site subcutaneous tissue, respectively; III IV, filled with ProRoot MTA respectively. animals killed 7 30 days after tube implantation, hemi-maxillas capsular both tubes, removed. Specimens processed evaluated...
To evaluate the morphology and impact of root canal preparation in maxillary incisors with palatogingival grooves (PGG).Twenty extracted human PGG were subjected to macroscopic analysis scanning electron microscopy (SEM). The following characteristics evaluated: depth, point origin cingulum, extension position on lingual surface. Furthermore, presence calculus, communications between system PGG, resorptions investigated. canals subsequently instrumented K-files three consecutive sizes. teeth...
Abstract Objective This study aimed to determine the correlation between vascular mast cells and inflammatory changes in potentially malignant disorders, compared oral squamous cell carcinoma (OSCC) varying degrees of dysplasia. Materials Methods Thirty samples were selected: 10 OSCC, leukoplakia, actinic keratosis. The toluidine blue technique was used on cells, hematoxylin eosin for analyzing lymphocytes, mitosis, vessels. quantification performed using ImageJ software after obtaining...
The present paper draw the attention of clinicians to investigate multiple slices computed tomography (CT) scan looking for a safe diagnosis so-called Garrè's osteomyelitis (GO) jaws, not uncommon disease characterized by astonishing bone growth. We report case involving left mandible 12-year-old girl presenting with bony enlargement at mandible. Initial examination revealed carious process tooth 36 radiographic apical rarefaction. However, we need take care this because other aggressive...
Angiosarcomas are rare and aggressive malignant tumors of endothelial cells, they have a vascular or lymphatic origin. Diagnostic evaluation includes biopsy to confirm the histopathological diagnosis, in addition magnetic resonance imaging delineate extent primary lesion before surgery. We report an unusual clinical event well-differentiated angiosarcoma nasogingival labial region female patient, 85-years-old, who sought care with increased sensitivity upper lip progressive worsening...
ABSTRACT Aim To evaluate the distribution of bacteria in teeth with pulp necrosis and apical granuloma. Materials methods Thirty-two extracted granulomas 16 cases isolated were sectioned stained Hematoxylin Eosin (H&E) Brown-Brenn staining for microscopic evaluation. The specimens observed as to location involved process their relationship periapical tooth structures soft tissues. Results Stainable Gram-positive Gram-negative found entire root canal system. Bacterial biofilms detected...
ABSTRACT We report a unique case of potassium aluminum sulfate oral dissolution leading to palatal chemical necrosis and extensive ulcers on the tongue. The patient, 47‐year‐old white, blind male, denied using cocaine or other illegal drugs that could cause such lesions. His self‐medication started as treatment for traumatic ulcerative lesion hard palate. After perforation, he another routine, mixing corticoid cream tandrilax tablets with gauze obturator. Our comprised removal all factors,...
O câncer de boca representa um problema saúde pública em todo o mundo, das neoplasias malignas que podem afetar a cavidade oral, carcinoma espinocelular (CEC), destaca-se por cerca 90% todas as lesões diagnosticadas na boca. Descrever diagnóstico caso (CEC) região assoalho bucal paciente tabagista. Paciente com 43 anos idade, sexo masculino, melanoderma, garimpeiro, cor parda, compareceu ao atendimento Policlínica Odontológica da Universidade do Estado Amazonas (UEA) para exame...
Abstract The purpose of this study was to investigate the tissue reaction stimulated by BaSO 4 ‐ and Bi 2 O 3 ‐containing White MTA Angelus, in comparison with white Portland cement, ProRoot MTA. Thirty‐six adult male Wistar rats ( Rattus norvegicus ), weighing between 250 300 g, were distributed into three groups n = 12) accordance period sacrifice (15, 30, 60 days). Four polyethylene tubes filled tested cements implanted dorsum each rat. Lateral wall served as negative control. After...
Periodontitis, a complex infectious disease that may lead to irreversible loss of periodontium, is considered predisposing agent for developing insulin resistance due the release inflammatory mediators, showing bilateral relationship with diabetes mellitus. The investigation periodontal requires clinical approach and complete intraoral radiographs, even increasing concerns about radiation exposure. Thus, this study assesses pixel linear analysis accuracy using digital radiography via Digora®...
