Use of photodynamic therapy and chitosan for inactivacion of Candida albicans in a murine model.

Background: The wide use of topical and systemic antifungal agents as the conventional treatment for oral candidiasis has caused Candida albicans to develop resistance to these agents. The aims of this study were to evaluate the effects of photodynamic therapy (PDT) and chitosan on buccal candidiasis and study the possible enhancive effect of chitosan on the photosensitizer methylene blue.

Methods: Thirty-five DBA/2 immunosuppressed mice were orally inoculated with a suspension of Candida albicans.

Clinical justification of dental radiology in adult patients: a review of the literature.

Although the radiological doses used by dentists are low individually, patients are often exposed to many repeat dental radiographic examinations. The "routine" use of dental radiography, such as screening of all patients using dental panoramic radiography (DPRs) or a random decision to take a dental radiograph, will inevitable lead to unnecessary patient exposure. The use of Radiographic Referral Criteria has now become a legal requirement for all practitioners following the adoption of European Legislation.

Shear bond strength of a self-etching adhesive in primary and permanent dentition.

Purpose: To assess the shear bond strength obtained with a new self-etching adhesive material (Adper Prompt-L-Pop) compared with the total-etch technique and posterior application of an adhesive (Prime & Bond NT) in both primary and permanent teeth.

Methods: 28 human teeth were selected (14 primary and 14 permanent). The vestibular and lingual surfaces were prepared in dentin, followed by application of the adhesive materials (Adper Prompt-L-Pop and Prime & Bond NT), in accordance with the instructions of the manufacturer.

New oral findings in Cohen syndrome.

Cohen syndrome is a hereditary disorder transmitted as an autosomal-recessive trait. Approximately 100 cases have been reported in the genetic and pediatric literature. Despite the fact that oral alterations are often observed in these cases, only 1 work has been published addressing this specific topic, and it tended to concentrate on periodontal abnormalities.

Marginal microleakage of two fissure sealants: a comparative study.

Purpose: An in vitro study was conducted to evaluate enamel marginal microleakage following acid etching of two fissure sealants of established clinical efficacy. The purpose of this study was to assess sealant leakage following etching in combination with the use of latest-generation adhesives.

Methods: Clinicians removed 22 human premolars without caries for orthodontic reasons, stored them in distilled water, and sealed the occlusal surface.
