Trauma to the lips and tongue can occur by accidental self-biting after dental treatment. After local anesthesia, it is likely that the patient may feel painless even in biting the tongue. In case of young children and disabled patients, the dentists should be careful not to bite the tongue. In this report, we present a case of deep lingual laceration due to biting the tongue in the course of dental treatment under general anesthesia. A 33 year-old male was transferred to our hospital to treat tongue laceration. Before 2 hour on arrival, he had received dental care under general anesthesia at a dental hospital for the disabled because of cooperation difficulty and cerebral palsy. During recovery from general anesthesia, he tried to bite his own tongue involuntary. The doctors and nurses tried to prevent the patient from being injured. Despite these efforts, massive bleeding occurred from the injured sites of the tongue. Because we could not communicate with him, we decided to evaluate the extent of the injury and treat the injured sites under general anesthesia. The laceration wound was sutured for nearly 1 hr general anesthesia. During recovery we inserted mouth prop into the oral cavity to prevent further injuries from tongue biting. After full recovery from general anesthesia he didn't try to bite his tongue. After 4 hour admission, he was discharged without other complications.

Gastrointestinal cyst found within the oral cavity has been reported as a rare occurrence with less than 40 cases. The tongue is the preferred site with almost 60% of cysts occurring within oral cavity. The cyst usually shows an asymptomatic swelling in the floor of the mouth, about 30% of affected individuals have symptoms related to difficulties with feeding, swallowing and respiration. The histopathologic features of the cyst vary with respect to the type of epithelium lining; gastric, squamous, intestinal and respiratory epithelium. The pathogenesis is not known, but it may be related to entrapment of undifferentiated endoderm within oral cavity during early fetal development. In this article, we report a case of a gastrointestinal cyst of the tongue in a 16-month-old girl.

Purpose: The aim of this study was to investigate the effect of tongue cleaner-equipped manual toothbrush on tooth cleanness, tongue cleanness and malodor index. Materials and methods: 504 subjects were included in this study. At 1st visit, basic information such as age, sex, smoking amount and alcohol consumption was recorded. Self assessment by individual subjects was performed regarding satisfaction to old toothbrush and toothbrushing habit. Tooth cleanness, tongue cleanness and malodor index was assessed by professional researcher. Tongue cleaner-equipped manual toothbrush was given to each subject with proper toothbrushing instruction. After 1 month passed, self assessment and researcher assessment regarding the same index were performed and analyzed statistically by chi-square test. Results: At 1st visit subjects seem to ignore tongue cleansing and showed poor tooth cleanness index, tongue cleanness index and malodor index, however the same subjects were motivated to clean their tongue and teeth and presented statistically improved distribution pattern in tooth cleanness index, tongue cleanness index and malodor index after using tongue cleaner-equipped manual toothbrush(p<0.01). Satisfaction to tongue cleaner-equipped manual toothbrush was 98%. Conclusion: Tongue cleaner-equipped manual toothbrush would be an effective tool for maintaining good oral hygiene through improving tooth and tongue cleanness and preventing malodor formation.

Tuberculosis is primarily a pulmonary disease and extrapulmonary involvement of the oral cavity is an infrequent occurrence accounting for 0.2 - 1.5% of all extrapulmonary sites. The authors report a case of primary tuberculosis of the oral tongue in a 60-years-old male patient who visited the clinic for ongoing tongue pain that he experienced for several months. The lesion was initially indistinguishable from the malignancy, but differential diagnosis was performed on the biopsy with Ziehl-Neelseen stain. After treatment with anti-tuberculosis, the oral lesion healed completely without surgery.

Objectives: The purpose of this study was to evaluate and compare the treatment outcomes of partial glossectomy with or without elective neck dissection in patients with tongue squamous cell carcinoma (SCCa). Materials and Methods: A total of 98 patients who were diagnosed with tongue SCCa and underwent partial glossectomy between 2005 and 2014 were evaluated. Only 14 patients received elective neck dissection, and 84 patients received only partial glossectomy. Results: There were 56 men and 42 women with a mean age of 57 years and mean follow-up period of 33.7 months. There were 70 patients graded as T1 and 28 as T2. The total occult metastasis rate was 17.3%. The 5-year overall survival rate was 83.3% with elective neck dissection and 92.4% with observation. The 5-year disease-free survival rate was in 70.7% in the elective neck dissection group and 65.3% in the observation group. Conclusion: We retrospectively reviewed the records of 98 patients with tongue SCCa. These patients were divided into two groups, those who underwent elective neck dissection and those who did not. There was no statistically significant difference between the groups undergoing partial glossectomy with or without elective neck dissection.

Objectives: This study aimed to analyze the correlation between oral function, oral environment, and brain cognitive function in the elderly. Methods: The subjects were 60 users of senior community center and elderly day care center. The survey was conducted from November to December 2018. Subjects were assessed by oral examination and myofunction test. Oral myofunction was measured using $IOPI^R$ and Lip de $Cum^R$. Survey data were analyzed using the statistical programs of PASW Statistics ver. 18.0. Results: Tongue muscle strength and lips muscle strength was higher in males than in females. The tongue and lip strengths were higher in the <81 years old group than the ${\geq}81$ years old group. Functional tooth analysis showed that there was a ${\geq}15$ teeth group ($40.91{\pm}7.36$) and a <15 teeth group ($32.52{\pm}7.14$). Lip muscle strength analysis showed that the ${\geq}15$ teeth group ($10.54{\pm}3.40$) was higher than the <15 teeth group ($8.20{\pm}2.41$, p<0.05). Tongue muscle strength, lumbar muscle strength, and functional tooth number were lower in the elderly subjects with mild cognitive impairment. Cognitive function was significantly correlated with functional tooth number (r=0.386, p<0.001), tongue strength (r=0.478, p<0.001), and lip strength (r=0.281, p<0.05). Tongue strength was significantly correlated with lip strength (r=0.360, p<0.001) and functional tooth number (r=0.633, p<0.001). Lip strength was significantly correlated with functional tooth number (r=0.376, p<0.001). Conclusions: These results showed that age and functional tooth number influenced oral muscle strength and that the number of functional teeth and oral muscle strength were low in the elderly with mild cognitive impairment. Oral myofunction training and oral care program are suggested to improve the quality of life of the elderly.

Tardive dyskinesia (TD) is continuous, repetitive movement disorder of tongue, lip or jaw, induced by medication. It causes pain and dysfunction of oral structures but also interferes with dental treatment and overall social life of patients. As a dentist, it is imperative to recognize and manage TD, although currently, there is no definitive treatment for TD. This article reports a patient with TD of tongue, successfully managed with an oral appliance mimicking sensory tricks. Considering the limited treatment options for TD, an oral appliance, a simple and conservative approach, can be a meaningful treatment for some patients with orofacial dyskinesia.

Objectives: The purpose of this study was to investigate the oral health and hygiene in the neurosurgical patients in intensive care unit(ICU). Methods: The subjects were 92 neurosurgical patients in intensive care unit(ICU) from March, 2011 to December, 2012. The oral examination consisted of number of residual teeth, DMFT index, clinical attachment loss, gingival index, plague index, and Candida species colony of tongue and saliva. Plaque was inoculated from tongue and saliva and incubated in 36.5C incubator for 48 hours using $Dentocult^{(R)}$ CA(Orion Diagnostica, Espoo, Finland). Glasgow coma scale(GCS) was measured to evaluate the consciousness of the patients on the basis of medical record. Results: Oral health was poor in clinical attachment loss and gingival index. Oral hygiene in neurosurgical patients in ICU was very poor due to high plaque index and Candida colonization of tongue and saliva. Plague index was closely related to Candida colonization of tongue and saliva(p<0.05). Conclusions: Oral health and hygiene of patients in neurosurgical ICU were very poor. More careful oral hygiene care is very important and necessary to enhance the oral health improvement of the neurosurgical patients in ICU.

Out of all oral malignant tumor, malignant lymphoma occurs in only 3.5%. Especially, most of the primary malignant lymphomas, which occur in the head & neck region are high-grade diffuse large B-cell lymphoma and mucosa-associated lymphoid tissue (MALT) marginal zone B-cell lymphoma is very rare. In the head & neck region, malignant lymphoma is reported to occur in the thyroid, salivary gland, trachea, larynx, orbital lobe and the Waldeyer's ring. Among the Waldeyer's ring, palatal tonsil is reported to be the most common region, but, only 1 case report was published in Korea. Until now, there were no case reports of MALT lymphoma that occurred in the tongue. The purpose of this case report is to report and discuss on a case of MALT lymphoma of the tongue.

Purpose: The goal of this systematic review was to compare the use of cone-beam computed tomography (CBCT) with that of computed tomography (CT) for volumetric evaluations of the tongue and oral cavity. Materials and Methods: A search for articles was conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-analyses guidelines. The PubMed, Scopus, ScienceDirect, and SAGE Journals databases were searched for articles published between 2011 and 2021. Articles were screened and assessed for eligibility. Screening involved checking for duplication, reading the title and abstract, and reading the full text. Results: The initial search retrieved 25,780 articles. Application of the eligibility criteria yielded 16 articles for qualitative analysis. Multiple uses of CBCT were identified. In several studies, researchers assessed the volumetric correlation between tongue and oral cavity volumes, as well as other parameters. Post-treatment volumetric evaluations of the oral cavity were also reported, and the reliability of CBCT was assessed. The use of CT resembled that of CBCT. Conclusion: CBCT has been used in the evaluation of tongue and oral cavity volumes to assess correlations between those volumes and with the upper airway. It has also been used for volumetric evaluation after surgical and nonsurgical procedures and to assess the relationships between tongue volume, tooth position, occlusion, and body mass index. Participants with obstructive sleep apnea and malocclusion have been evaluated, and the reliability of CBCT has been assessed. In the included studies, CT was utilized for similar purposes as CBCT, but its reliability was not assessed.
