Association of calcified carotid artery plaque in panoramic images and diagonal earlobe crease.

Objectives:: Brazilians who are free of traditional atherogenic risk factors frequently suffer myocardial infarctions (MI). Calcified carotid artery plaque (CCAP) on panoramic images (PIs) has been shown to be a validated "risk indicator" of future MIs. The diagonal earlobe crease (DELC) is likewise a validated "risk indicator" of future MI.

Primary Diffuse Large B Cell Lymphoma Mimicking Hyperplastic Reactive Lesion (Lymphoma of the Oral Cavity).

Objective: To report a case of a challenging oral diagnosis involving a primary diffuse large B cell lymphoma of the oral cavity mimicking a hyperplastic reactive lesion.

Case Report: A 72-year-old male patient was referred to the Department of Stomatology presenting a proliferative nodular lesion in the anterior region of the mandible involving the anterior teeth. The clinical examination revealed anterior teeth affected by periodontal disease, suggesting the nodular cession hyperplastic reaction.

Mechanical Ventilation and Cytopathological Changes in the Oral Mucosa.

Background: The oral mucosa is an important defense barrier to penetration of microorganisms. Thus, changes in the oral epithelium might indicate risk for infection in intensive care patients receiving mechanical ventilation.

Objective: To evaluate the oral mucosa of intensive care patients who did or did not receive mechanical ventilation by using liquid-base exfoliative cytology.

Massive Submandibular Sialolith: Complete Radiographic Registration and Biochemical Analysis through X-Ray Diffraction.

Sialolithiasis is a pathologic condition that affects 60 million people per year, which is caused by the presence of calcified structures, named sialoliths, inside the salivary glands and their salivary ducts. Despite the large incidence of sialolithiasis, its etiology is still unknown. In the present case report, a 47-year-old female patient, presenting with local pain and hampered mouth opening, underwent a surgical approach for the removal of a 20 mm sialolith, which was further analyzed through X-ray diffraction.

Orthodontic treatment of a patient with dentin dysplasia type I.

Dentin dysplasia is a genetic disorder of the teeth that affects the dentin and the pulp. Type I is sometimes called "rootless teeth," because of the loss of organization of the root dentin, which often leads to a shortened root length. The purpose of this article was to present a rare clinical case of a girl who was diagnosed with dentin dysplasia type I when she was referred for an orthodontic evaluation.

Laboratory methods and biomarkers in the evaluation of bisphosphonate effects on body tissues: a literature review.

Bisphosphonates are extensively used to treat bone metabolism disorders; meanwhile, these drugs have important side effects such as jaw osteonecrosis and femoral fracture. Therefore, studies have been conducted aimed at better understanding their mechanism of action and determining a course of action to avoid these side effects. We present here a literature review focusing on the laboratory methods available for investigating bisphosphonate effects on body tissues.

Clinical diagnosis of hyposalivation in hospitalized patients.

Objective: The aim of this study was to evaluate the effectiveness of clinical criteria for the diagnosis of hyposalivation in hospitalized patients.

Material And Methods: A clinical study was carried out on 145 subjects (48 males; 97 females; aged 20 to 90 years). Each subject was clinically examined, in the morning and in the afternoon, along 1 day.

Assessment of variations of the mandibular canal through cone beam computed tomography.

The neurovascular bundle may be vulnerable during surgical procedures involving the mandible, especially when anatomical variations are present. Increased demand of implant surgeries, wider availability of three-dimensional exams, and lack of clear definitions in the literature indicate that features of anatomical variations should be revisited. The objective of the study was to evaluate features of anatomical variations related to mandibular canal (MC), such as bifid canals, anterior loop of mental nerve, and corticalization of MC.

Histological diagnosis of oral lesions with cutting needle biopsy: a pilot study.

Objectives: The aim of this pilot study was to evaluate the effectiveness of cutting needle biopsy in the diagnosis of solid oral lesions.

Material And Methods: The biopsies were carried out on seven patients who presented with solid oral lesions with sizes ranging from 2 to 6 cm. Specimens were obtained from each lesion before conventional biopsies using a cutting needle with 18-gauge x 9 cm (MD TECH, Gainesville, FL, USA).

Characterisation of additional mental foramina through cone beam computed tomography.

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 and orthognatic surgeries. The aim of this study is to characterise additional mental foramina (AMF) through cone beam computed tomography (CBCT) images, by describing their frequency, size, location and direction of their associated bony canals, as well as to assess their corresponding ipsilateral and contralateral mental foramina (MF). CBCT images from 285 patients were analysed.
