Association between hypertension, oral microbiome and salivary nitric oxide: A case-control study.

Background: Nitric oxide (NO) produced in the oral cavity is a powerful resource for the human body, especially when NO-syntethase production is not adequate. The role of oral microbiome in determining blood pressure levels has been linked to the active role of some bacterial species involved in the nitro-reducing process. In the present study we investigated the correlation between selected oral microbiome characteristics, nitric oxide (NO) concentration in saliva and their association with hypertension.

Circulating miR-21 as a Potential Biomarker for the Diagnosis of Oral Cancer: A Systematic Review with Meta-Analysis.

Head and neck squamous cell carcinoma (HNSCC) is one of the main neoformations of the head-neck region and is characterized by the presence of squamous carcinomatous cells of the multi-layered epithelium lining the oral cavity, larynx, and pharynx. The annual incidence of squamous cell carcinoma of the head and neck (HNSCC) comprises approximately 600,000 new cases globally. Currently, the 5-year survival from HNSCC is less than 50%.

Impact of Elderly Masticatory Performance on Nutritional Status: An Observational Study.

Masticatory limitations on the dietary habits of edentulous subjects restrict their access to adequate nutrition, exposing them to a greater risk of protein energy malnutrition. The aim of this study is to verify the existence of an association between Masticatory Performance (MP) and nutritional changes in the elderly. 76 participants were enrolled.

Assessment of second (I) and third (I) molar indices for establishing 14 and 16 legal ages and validation of the Cameriere's I cut-off for 18 years old in Chilean population.

This retrospective cross-sectional study has two-fold aims: the first is to assess new cut-offs at the legal age thresholds (LATs) of 14 and 16 years old and the second is to validate the cut-off of third molar index I=0.08 for 18 years of age in Chilean people. Orthopantomographs from 822 Chilean children aged from 11 to 22 (472 girls and 350 boys) were analysed.

Composite partial crowns for injured anterior teeth.

Falls and collisions are the most commonly reported causes of dental injuries. These accidents involve principally the maxillary central incisors, causing uncomplicated crown fracture. Many materials and techniques can be used to restore injured anterior teeth.

Effect of c-Met expression on survival in head and neck squamous cell carcinoma.

The proto-oncogene c-Met has been suggested to be associated with progression of squamous cell carcinoma of the head and neck. The aims of the present study were to assess the prevalence of c-Met expression in oral squamous cell carcinoma (OSCC) and to verify whether c-Met can be considered a marker of prognosis in these patients. In a retrospective study, a cohort of 84 OSCC patients was investigated for c-Met expression and its cellular localization by immunohistochemistry.

Fiber-reinforced composite fixed partial denture to restore missing posterior teeth: a case report.

In patients refusing implant surgery for psychological reasons, when minimal tooth reduction is desired, a fiber-reinforced composite inlay fixed partial denture (IFPD) can be used to replace missing teeth. In comparison to other restorative systems this conservative approach carries a lower risk of pulp exposure and/or periodontal inflammation, maintaining the health of supporting tissues. The purpose of this case report is to describe the clinical procedure for fabricating an IFPD with a pre-impregnated glass fiber system and a hybrid composite.

Prosthetic rehabilitation of a child affected from anhydrotic ectodermal dysplasia: a case report.

The aim of this clinical report is to describe the management of a young patient, affected by ectodermal dysplasia, during a nine-year period. Dental treatment can vary depending on the severity of the disease (tooth size, morphology, and amount of available alveolar bone). New technologies, such as adhesive dentistry, and new materials, such as composite resin, represent current options in the management of the dental rehabilitation of patients affected by ectodermal dysplasia.

Restoration of anterior teeth with indirect composite partial coverage crowns: a clinical report.

When an esthetic restoration with minimal tooth reduction is desired, for example in patients with uncomplicated tooth fractures, composite partial coverage crowns may be a therapeutic option. The indirect composite restoration allows restoration of the original tooth anatomy, function, and esthetics to be reproduced while preserving tooth structure. The use of composite partial coverage crowns to restore fractured anterior teeth is described.
