Common Oral Lesions.

Familiarity with common oral conditions allows clinicians to observe and treat patients in the primary care setting or refer to a dentist, oral surgeon, otolaryngologist, or other specialist. Recurrent aphthous stomatitis (canker sores) is the most common ulcerative condition of the oral cavity. Recurrent herpes simplex labialis and stomatitis also commonly cause oral ulcers. Corticosteroids, immunocompromise, antibiotics, and dentures can predispose patients to oral candidiasis. Benign migratory glossitis (geographic tongue) occurs in up to 3% of the population but generally lacks symptoms, although some people experience food sensitivity or a burning sensation. Hairy tongue is associated with a low fiber diet, tobacco and alcohol use, and poor oral hygiene in older male patients. Generally, hairy tongue is asymptomatic except for an unattractive appearance or halitosis. Tobacco and alcohol use can cause mucosal changes resulting in leukoplakia and erythroplakia. These can represent precancerous changes and increase the risk of squamous cell carcinoma. Mandibular and maxillary tori are common bony cortical outgrowths that require no treatment in the absence of repeat trauma from chewing or interference with dentures. Oral lichen planus occurs in up to 2% of individuals and can present as lacy reticulations or oral erosions and ulcerations. Traumatic buccal mucosal fibromas and labial mucoceles from biting can be excised.

Drug-induced black hairy tongue.

Black hairy tongue (BHT) is a benign, self-limiting disorder characterized by abnormally hypertrophied and elongated filiform papillae on the surface of the tongue. The prevalence of BHT is quite variable, ranging from 0-53.8% depending on the population. Many predisposing factors to BHT exist, and several drugs and drug classes have been implicated in causing this disorder. A modified Naranjo adverse drug reaction probability nomogram specific for BHT was used to rate causality for the available published case reports of drug-induced BHT. From the available data, antibiotics and drugs capable of inducing xerostomia are the drug classes that have modest evidence of causality and a rational mechanism. The presence of underlying predisposing factors in these cases along with the variable prevalence of BHT make drawing firm conclusions difficult. Treatment for BHT involves eliminating any predisposing issues and practicing scrupulous oral hygiene. Drug therapy and physical removal of the elongated filiform papillae are available for resistant cases. Clinicians should be aware of the prevalence, the predisposing factors and drug classes that may play a role in the development, and the treatment of BHT.

[Tongue coating, mouth odor, gustatory sense disorder - earlier and new treatment options by means of tongue scraper]. / Zungenbelag, Mundgeruch und Schmeckstörung - bisherige Behandlungsmethoden und neue Therapieoption durch mechanische Zungenreiniger.

The tongue is said to be the mirror of physical health. The tongue dorsum is most delicate regarding the sense of touch. Pathologic coating of the tongue accounts for paresthesia during chewing, swallowing, speaking, tasting, and also may result in mouth odor. Tongue coating can result from increased formation or decreased natural abrasion, and from xerostomia or dyschylia. In clinical otorhinolaryngology pathologic tongue coating often is idiopathic or present after surgery of the oral cavity or pharynx. Critical analysis of published studies reveals that effectivity and justification to administer xenobiotics or vitamins in that condition is doubtful. Recently, it has been shown that tongue fur was able to be reduced by an easy-to-handle mechanical tongue cleaner or tongue scraper. Due to its simple use, tongue scrapers could be a welcome supplement for the treatment of tongue fur, mouth odor, and in particular cases, to enhance gustatory sense. Preliminary results of an ongoing prospective trial showed that tongue scrapers can effectively be applied after surgery of the oral cavity or pharynx. After tonsillectomy, tongue fur seemed to be reduced and gustatory sense to be enhanced when tongue scrapers were applied during postoperative care. After confirming these promising results in further investigations, an inexpensive and simple option for the treatment of a large amount of patients in clinical otorhinolaryngology would exist.

The association of tongue scalloping with obstructive sleep apnea and related sleep pathology.

OBJECTIVE: The association between OSAS and patient history and physical exam findings is previously established; however, to our knowledge there are no studies that evaluate the role of tongue scalloping as a reliable clinical indicator for OSA, snoring, or the presence of other sleep pathology as evidenced by polysomnography. This study evaluates the hypothesis that such an association exists. SUBJECTS AND METHODS: Sixty-one otolaryngology clinic patients were evaluated by history and physical exam for the presence and degree of tongue scalloping, snoring, and other previously established clinical indicators for sleep-disordered breathing and obstructive apnea. Twenty-five of the 61 study patients were additionally evaluated by overnight polysomnography to provide conclusive diagnosis of sleep pathology. The degree of tongue scalloping was graded from 0 to 3 and its significance as a screening, diagnostic, and predictive factor for sleep pathology was then statistically determined. RESULTS: Twenty-seven patients (44%) had known or newly documented OSA and 47 (77%) had a history of snoring. Twenty-seven patients (44%) had some degree of tongue scalloping (1-3) and 74% of these patients were male. The presence of any degree of tongue scalloping (grade 1-3) in patients with known or newly documented OSA showed sensitivity, specificity, PPV, and NPV of 52%, 68%, 70%, and 50% respectively. The presence of tongue scalloping in patients with either known snoring history or newly documented snoring showed sensitivity, specificity, PPV, and NPV of 47%, 64%, 81%, and 26% respectively. Presence of tongue scalloping was 71% specific for abnormal sleep efficiency (<85%), 70% specific for abnormal AHI (>5), and 86% specific for nocturnal desaturation >4% below baseline. Presence of tongue scalloping also showed PPV of 67% for abnormal AHI, 89% for apnea or hypopnea, and 89% for nocturnal desaturation. Presence and severity of tongue scalloping showed positive correlation with increasing Mallampati and modified Mallampati airway classification. CONCLUSIONS: In high-risk patients we found tongue scalloping to be predictive of sleep pathology. Tongue scalloping was also associated with pathologic polysomnography data and abnormal Mallampati grades. We feel the finding of tongue scalloping is a useful clinical indicator of sleep pathology and that its presence should prompt the physician to inquire about snoring history.

Regression of oral hairy leukoplakia during zidovudine therapy.

We describe two patients with human immunodeficiency virus infection and oral hairy leukoplakia whose tongue lesions resolved on oral zidovudine therapy. During therapy, each patient had a measurable reduction in human immunodeficiency virus antigen corresponding with clinical regression of oral lesions. The clinical course suggests that zidovudine may have contributed to the resolution of these lesions either indirectly through immunologic improvement or through an antiviral effect.
