“…Men demonstrated a higher prevalence than women, found in our as well as in other studies [26, 20]. The condition indicates either a defective desquamation of the cells in the central column of filiform papillae and in the formation of highly elongated cornified spines or hairs, alternatively that the rate of formation of keratinized material may be increased [31, 33]. …”

The mucosal membrane of the oral cavity displays at times classical developmental lesions considered to be variations of normal structures rather than having disease characteristics. Of these lesions leukoedema, Fordyce granules, geographic-, fissured- and hairy tongue, median rhomboid glossitis and lingual varices were studied in 598 patients referred to the School of Dentistry, Tehran, Iran. The prevalence was studied in relation to age, gender, occupation, education, smoking habits, general health, addictions and or drug therapies. Oral developmental lesions were seen in 295 patients (49.3%). Only Fordyce granules (27,9%), fissured tongue (12,9%), leukoedema (12,5%) and hairy tongue (8,9%) had enough cases for statistical analysis. Three of these lesions increased with age but not fissured tongue. All were more common in men. After adjusting for age, the parameters education, occupation and complaints upon referral had little influence on the prevalence of the lesions. Fewer Fordyce granules were seen in oral mucosa of smoking men. Leukoedema and hairy tongue were significantly associated with smoking, leukoedema with diabetes mellitus. We conclude that there was a highly significant association between these oral lesions and age, gender and smoking. Few significant associations were found between oral lesions and general diseases.

Sensing in the Mouth: A Model for Filiform Papillae as Strain Amplifiers

2016

Texture perception of foods is a common yet remarkably unstudied biophysical problem. Motivated by recent experiments reporting the presence of corpuscular endings in tongue filiform papillae, we develop in this work a mechanical model of the human tongue covered with filiform papillae in the form of elastic beams. Considering the typical flows that occur in the mouth during oral evaluation of Newtonian liquids, we suggest that filiform papillae may act either as direct strain sensors and/or as indirect strain amplifiers for the underlying mucosal tissue. Application of this model may also be valid for other biological appendages, such as primary cilliae and superficial neuromasts.

Lansoprazole induced black hairy tongue has been rarely reported. The purpose of this paper is to report a case of lansoprazole induce black hairy tongue and review the literature. A 75 year man from eastern part of Kathmandu presented with black hairy fine growth from tongue along with discomfort, burning and halitosis from oral cavity after taking lansoprazole for acute peptic disease(APD) from over the counter and after discontinuation of lansoprazole, black hairy tongue was resolving. Clinically and histopathologically: lansoprazole induced black hairy tongue was confirmed. Black hairy tongue is characterized by abnormal hypertrophy and elongation of filliform papillae.. Lansoprazole is a proton-pump inhibitor (PPI) with a racemic 1:1 mixture of the enantiomers dexlansoprazole which inhibits the stomach's production of gastric acids.
