Detection of Microparticles of Different Origins in Implant Prostheses and Abutments.

Purpose: To assess whether particles from metal and other alloplastic materials detected in tissues surrounding dental implants could have other sources of origin besides biotribocorrosion or detachment from the implant surface.

Materials And Methods: A total of 52 prostheses were randomly tested at various stages of manufacture. Identification of the detached microparticles was performed using light field microscopy and comparison with previously obtained microscopic images.

Current understanding of genetic polymorphisms as biomarkers for risk of biological complications in implantology.

Background: In the last decade, multiple studies have been published that analyze the relationship between the risk of experiencing biological complications with implants and the presence of certain types of genetic polymorphisms. In the present report, we analyze the controversies that have arisen from this important area of investigation and synthesize the most prominent aspects of knowledge related to this possible etiopathogenic relationship.

Material And Methods: For this review, the biomedical databases PubMed-Medline, SciELO, and DOAJ were used.

Salivary cortisol determination in patients from the Basque Country with recurrent aphthous stomatitis. A pilot study.

Objectives: Stress and anxiety are controversial factors involved in the complex pathogenesis of Recurrent Aphthous Stomatitis (RAS). The determination of salivary cortisol is a useful, simple and safe test to detect states of high stress or anxiety. The aim of this study is to check for changes in salivary cortisol levels in patients with RAS during periods of active disease.

Salivary levels of Tumour Necrosis Factor-alpha in patients with recurrent aphthous stomatitis.

Objectives: Recurrent aphthous stomatitis (RAS) is a common pathology of the oral mucosa with a complex and multifactorial etiology. Tumour Necrosis Factor-alpha (TNFα) is a cytokine with an important but not well-known role in the development of new lesions in RAS patients. Modifications of salivary levels of TNFα in RAS patients during the active periods of the disease have been measured in this work.

Isolation of Candida dubliniensis in denture stomatitis.

Objective: To describe the isolation of Candida dubliniensis from a patient with denture stomatitis and to compare with the presence of yeasts in the oral cavities of denture wearers.

Design: One hundred and fifty-two Candida isolates were recovered through oral swabs from denture as well as the underlying mucosa from 100 patients wearing denture. For detection and identification of fungal isolates, standard phenotypic and genotypic methods were used.

Primary oral squamous cell carcinoma arising around dental osseointegrated implants mimicking peri-implantitis.

Prosthodontic rehabilitation using dental implants has become a common practice in dentistry at the present time. The number of complications related to dental osseointegrated implants has increased according to the generalization of its use along the last decade. Among the most common of these complications are chronic inflammatory conditions affecting both hard and soft tissues around dental implants.
