Black hairy tongue in a patient with amyotrophic lateral sclerosis

Oral hygiene in patients with motor neuron disease requires attention: A cross-sectional survey study

Aims

Motor Neuron Disease (MND) is a progressive neurodegenerative neuromuscular disease, which can progressively impair arm‐hand function. Needs and barriers of MND patients and their caregivers in performing oral hygiene were studied.

Methods

An online survey was sent to 706 MND patients. The questions of the survey included self‐reliance, self‐reported oral health, and oral hygiene. The oral health‐related quality of life (GOHAI‐NL) and the subjective well‐being (ALSAQ‐5) were also measured.

Results

A total of 259 patients responded (36.7%), of which 71.9% stated not to be informed about the importance of maintaining good oral health by their MND treatment team. Moreover, 40.4% would like to receive help concerning oral hygiene from a dental professional. 19.8% were not satisfied about oral care as conducted by themselves or their caregivers. Patients who do not ask for support with their daily oral care had a significantly worse oral health‐related quality of life compared to patients who do ask for support.

Conclusions

The support for daily oral hygiene of MND patients and their barriers to requesting support needs more attention from both MND‐treatment teams and general dental professionals.

Prednisolone-Induced Hairy Tongue: A Case Report

Hairy tongue is a benign and mostly asymptomatic disorder characterized by elongation of papillae with typical hairy-like appearance on the dorsal surface of the tongue. Many medical conditions, antibiotics, and drugs inducing xerostomia are associated with hairy tongue. In this article, we report a female patient with polymyalgia rheumatica who developed hairy tongue following treatment with prednisolone. Clinicians should be aware of the predisposing factors and drugs that may have a role in the development of hairy tongue.

Non-invasive intravital observation of lingual surface features using sliding oral mucoscopy techniques in clinically healthy subjects

To investigate intravital morphological features of the broader area of the lingual mucosa in clinically healthy subjects, and to attempt to evaluate subclinical conditions, we evaluated detailed intravital morphological features of the lingual mucosa using our newly developed oral contact mucoscopy techniques. Clinically healthy subjects (female: 19-22 years, average age: 20.27 years, and n = 28) were enrolled. A position indicator stain was placed on the lingual mucosal surface, and sliding images were captured and then reconstructed. In addition, the lingual mucosa was divided into six areas, and morphometry of the fungiform and filiform papillae was performed. The results were statistically analyzed. There were two morphological features among clinically healthy subjects involving the filiform papillae: the length of the papillae and the degree of biofilm (tongue coat) deposition. We defined a modified tongue coat index (mTCI) with scores ranging from 0 (tongue coating not visible) to 0.5, 1, 1.5, and 2 (thick tongue coating) for six sections of the tongue dorsum. No subjects received a score of 2. Significant differences were found in the mTCI between the six sections of the tongue dorsum, especially between the posterior areas and the lingual apex. The fungiform papillae of some subjects exhibited elongated morphological changes. Our findings suggest that magnified lingual dorsum examination of a broader area is especially important in accurate screening for subclinical or transient conditions of potential lingual mucosal diseases. For this purpose, our new oral mucoscopy and non-invasive intravital observational techniques were especially effective.

Black Hairy Tongue: Predisposing Factors, Diagnosis, and Treatment

Black hairy tongue (BHT) is a benign condition commonly found among people who smoke, have poor oral hygiene, are immunocompromised, or have a medical condition limiting their ability to practice good oral hygiene. Though this condition is harmless, patients need to be educated on etiology as many common medications are associated with this condition. Patients being placed on certain antibiotics or antipsychotics should be educated on the importance of good oral hygiene or cessation of habits that promote BHT. Similarly, those with medical conditions increasing the risk for the development of BHT should schedule routine visits with their dentist or dental hygienist. Prognosis is good, and treatment consists of gentle brushing of the tongue, but many anecdotal reports exist demonstrating the use of medications or other products to treat this condition. This review addresses the epidemiology, clinical presentation, pathophysiology, etiology, histology, differential diagnosis, and treatment of BHT and lists all of the medications reported to cause this condition.

Orofacial function and monitoring of oral care in amyotrophic lateral sclerosis

OBJECTIVE

The aim was to assess orofacial function and monitor oral care in patients with amyotrophic lateral sclerosis (ALS) to maintain oral comfort and oral health.

MATERIALS AND METHODS

A case series of 14 patients newly diagnosed with ALS accepted to participate in a quality improvement project. After initial examinations, baseline oral conditions were obtained and the patients were seen every 3 months. Nordic Orofacial Test-Screening (NOT-S) was used for evaluation of orofacial function.

RESULTS

Patients were grouped according to initial symptoms in a bulbar group and a spinal group with eight and six patients, respectively. The mean age at diagnosis was 62.8 years. All were dentate with a mean of 26.7 natural teeth. Most patients had very good oral and dental conditions. As expected, orofacial functions were differently affected in the two groups; at initial NOT-S registration, the mean total score was 5.6 (range 3-8 domains) in the bulbar group and 0.7 (0-2 domains) in the spinal group. At final registration, the corresponding figures were 6.1 and 3.2. Oral and dental aids were introduced according to need.

CONCLUSIONS

In the bulbar group, several orofacial functions became impaired at an early stage of disease development, and at final registrations many vital orofacial functions were severely compromised. The spinal group was less severely affected orally. However, all individuals irrespective of type of initial symptoms needed assistance in performing oral hygiene measures in the latter part of the disease period. Good oral health and oral comfort could be maintained in all participants and no other dental treatment was needed.
