A Review on Xerostomia and Its Various Management Strategies: The Role of Advanced Polymeric Materials in the Treatment Approaches.

The medical term xerostomia refers to the subjective sensation of oral dryness. The etiology seems to be multifactorial with the most frequently reported causes being the use of xerostomic medications, neck and head radiation, and systematic diseases (such as Sjögren's syndrome). Xerostomia is associated with an increased incidence of dental caries, oral fungal infections, and difficulties in speaking and chewing/swallowing, which ultimately affect the oral health-related quality of life.

Expression of matrix metalloproteinases 9 and 12 in actinic cheilitis.

Aim: To investigate the role of matrix-degrading metalloproteinases 9, 12 (MMPs), as mediators of functional connective tissue damage in actinic cheilitis.

Methods: Thirty five formalin-fixed, paraffin embedded specimens of actinic cheilitis, and twelve specimens of normal lower lip vermillion, which were obtained by the archives of the Department of Oral Medicine and Maxillofacial Pathology, were examined. From each block, 5 μm thick sections were cut and routinely stained with Hematoxylin and Eosin.

Black hairy tongue in a 2-month-old infant.

Black hairy tongue (BHT) is an unusual condition in adults, and is characterised by marked accumulation of keratin on the filiform papillae of the dorsum of the tongue resulting in a hairlike appearance. The colour of the papillae may vary from brown to black. We describe a case of BHT in a 2-month-old infant.

Increased anxiety level and high salivary and serum cortisol concentrations in patients with recurrent aphthous stomatitis.

Recurrent aphthous stomatitis (RAS) is one of the most common oral mucosal disorders. The aim of the study was to determine any association between anxiety levels and concentrations of salivary and serum cortisol in patients with RAS. It has been suggested that stress with its presumed effects on the immune system, constitutes one of the major causative agents of RAS.
