Black hairy tongue in a patient with amyotrophic lateral sclerosis.

Black hairy tongue (BHT) is a condition characterized by the elongation of filiform papillae associated with a marked discoloration, from yellowish-brown to black, and a thick lingual coating. BHT is usually observed in the elderly and in patients with limited self-sufficiency, as a consequence of poor oral hygiene. In this perspective, the patients affected by amyotrophic lateral sclerosis (ALS) represent a high-risk category for the occurrence of BHT.

Probing depth in periodontal pockets: In vitro evaluation of contributions to variability due to probe type and operator skill.

Periodontal probing aims at detecting the presence, type and gravity of periodontal diseases influencing distance between gingival margin and connective ligament. Measurements in vivo are affected by substantial uncertainty, owing, for example, to probe features, anatomic variations and operator's skill. Inadequate reproducibility in periodontal probing may lead to diagnostic mistakes and inappropriate therapeutic decisions.

Application of the novel method in the diagnosis and treatment of median rhomboid glossitis Candida-associated.

The aim of this work is to demonstrate how current molecular techniques should be integrated in the diagnostic process and can have a crucial role in the management of oral fungal infections. A case of median rhomboid glossitis Candida-associated and its resolution will be described step by step. At the time of the first observation, the lesion on the surface of the tongue did not respond to the previous administration of topical antifungal agent, such a nystatin.

Microbial changes in subgingival plaque and polymicrobial intracellular flora in buccal cells after fixed orthodontic appliance therapy: a preliminary study.

The oral ecosystem is strictly related to a balance maintained by specific niches recognized as sites, where oral bacteria can metabolize avoiding the immune system response. The oral bacteria species that colonize the ecological niches vary during fixed orthodontic treatment, with a prevalence of periodontal bacterial species. Qualitative analysis of five periodontal pathogens was used to investigate the microbial colonization rate in the crevice and buccal epithelial cells.

Oil Essential Mouthwashes Antibacterial Activity against Aggregatibacter actinomycetemcomitans: A Comparison between Antibiofilm and Antiplanktonic Effects.

The aim of this work is to determine the antibacterial activity of three marketed mouthwashes on suspended and sessile states of Aggregatibacter actinomycetemcomitans. The efficacy of two commonly used products in clinical practice, containing essential oils as active ingredients (menthol, thymol, methyl salicylate, and eucalyptol) in association with or without alcohol, has been evaluated in comparison with a chlorhexidine-based mouthwash. The microtiter plate assay, in order to obtain a spectrophotometric measurement of bacterial responses at growing dilutions of each antiseptic, was used for the study.
