Various mucosal lesions are originated in oral cavity and trauma is most common cause of these lesions. Definitive treatment of these lesions is stop of traumatic events and removal. There are two representative removal methods in medical fields; conventional mess or LASER. Compare to conventional mess technique, LASER has several advantages such as bleeding control, pain reduction. Of the various LASER systems, $CO_2$ LASER is regarded as best choice for general practitioners due to its convenience, universal use and high cost/benefit effects. In these article, we report the treatment cases of mucocele, fibroma, and leukoplakias using $CO_2$ LASER. Eventhough there are malignancy potential of oral mucosal lesion especially leukoplakias, careful history taking, clinical examination, and regular check-up will help the general practitioners to manage these lesions. Simple and relatively safe oral mucosal lesions have to be treated more in general dental practitioners.

The detection of foreign bodies in the upper-aerodigestive tract is a fairly frequent event and can occur in various areas and for various reasons. In rare cases, foreign bodies can simulate a neoplasia. We evaluated similar cases during emergency regimen with an oral cavity mucosal lesion, causing lockjaw, sore throat, dysphagia, and swelling of the submandibular and laterocervical region. Physical examination revealed an extensive mucosal ulceration in the floor of the mouth and the lateral surface of the tongue, comparable to oral cancer. During a second, more accurate assessment, a partially deteriorated iron supplement tablet was found embedded in a mucosal pocket. After removing the tablet, gradual normalization of the tissue was observed without any sequelae. This is one of the many reasons why it is advisable and useful in cases of oral lesions to collect a detailed medical history and to perform an accurate clinical evaluation, including inspection and palpation of the lesion, before proceeding to further diagnostic assessments, especially in elderly patients taking many medications. However unlikely, it is possible that difficulty in swallowing pills or tablets could generate tumorlike lesions.

This study was performed to evaluate the role of Waters' view and panoramic view for the interpretation of mucosal cyst of the maxillary sinus and to determine the radiographic features of that according to the sites and sizes. For this study, clinically 25 cases of mucosal cyst of the maxillary sinus were used, and experimentally with two dry skulls, rubber ball of 15mm in diameter for marked radiopacity, and two jelly balls of 8 and 20㎜ in diameter for the similar radiopacity to cyst were used. The 25 cases with 25 panoramic views and 15 Waters' views were first analyzed, and secondly, the radiographic features of artificial lesions attached to the each wall of the antrum on Waters' view and panoramic view were analyzed. The obtained results were as follows: At clinical analysis, 1. 4 cases of 13-14㎜, 4 cases of 15-19mm, 14 cases of 20-25㎜, 3 cases of over 30㎜ in dia- meter were found on panoramic views. And 24 cases of 25 cases showed no relationship with teeth, and only 1 case was associated with advanced periodontal disease 2. The majority of mucosal cysts appeared to arise the posterior portion of the floor of the sinus and were superimposed with the inominate line of zygoma and the horizontally linear image of hard palate on panoramic view. 3. Only 2 cases of 15 cases were identified on both films. At experimental analysis, 4. On Waters' view, the images of the artificial lesion of the anterior portion and midportion of the floor of the sinus were lessend in diameter compared with the real size. On panoramic views, the images of the lesion were more radiolucent with lessened diameter than images on Water' view. 5. The images of the lesion of the posterior wall and the posterior portion of the floor of sinus on panoramic view were well detected by the preeducated group but not or poorly detected by the non-preeducated observer group. 6. On Waters' view, both observer groups recognized that the cystic images of the posterior portion of the floor of the maxillary sinus were superimposed with the petrous portion of the skull.

Oral mucosal lesions with a papillary or verrucous surface are a heterogenous group of conditions with widely varying clinical behaviour. The etiology is variable and includes infective, traumatic or neoplastic processes. The majority of these lesions are precanceous lesion. Therefore, a biopsy is required to establish a diagnosis and the microscopic examination must be coordinated with the clinical findings. This paper reviews the clinical features and significance of papillary or verrucous lesions.

Sinonasal mucosal melanoma (SNMM) in the maxillary sinus is a rare disease condition. Compared to oral mucosal melanoma, SNMM has a bulky, exophytic, and polypoid appearance, is weakly pigmented, and associated with unspecific symptoms. Due to these features, SNMM in the maxillary sinus has been misdiagnosed as nasal polyps and chronic sinusitis. In this case report, we described SNMM occurring in the right maxillary sinus simulated as a cystic or benign lesion. Cortical bone thinning and expansion were observed around the mass. The excised soft mass was encapsulated and weakly pigmented. The mass was clearly excised and covered with a pedicled buccal fat pad graft. Diagnosis using immunohistochemistry with S-100 and homatropine methylbromide-45 (HMB-45) is critical for proper treatment.

This study was to find dental materials causing hypersensitivity reactions by carrying out patch tests in the patients with oral mucosal lesions to investigate the possibility of hypersensitivity reactions in etiology of oral mucosal lesions. 31 patients (female 26, male 5, age range 24-72 years) with oral mucosal lesions were classified as patient group, and 41 volunteers (female 24, male 17, age range 23-40 years) without oral mucosal lesion, systemic disease and history of allergy as control group. The obtained results were as follows: 1. There were various dental restorations in most of patient group and control group, 29(94%) in 31 patient group, 35(85%) in 41 control group. 2. Among sites of oral mucosal lesions, buccal mucosa was the most common site with 60%, followed by gingiva with 24%, tongue with 16%. Lesions in contact with restorations were highly 90% in tongue and 89% in buccal mucosa, but comparatively lower 53% in gingiva. 3. The ratio of positive reactions to the patch test in patient group was significantly higher than the control group (p<0.05). 4. Dental materials causing positive reactions to the patch test were mainly mercury(19%), potassium dichromate(16%), cobalt chloride(16%) in patient group, cobalt chloride(17%) in control group. 5. In 20 patients with lichen planus, 8 patients(40%) showed positive reactions to the patch test.

Background: Lipomas are benign soft tissue neoplasms of mature adipose tissue commonly occurring in the trunk or extremities. But, intraoral lipomas are rare entities which may be only noticed during routine dental examinations. Especially intramuscular lipomas on the tongue have been reported very rarely. In this study, we report a case of intramuscular lipoma on tongue, with a review of the literature from 1978 to 2019, providing data on age, gender, location, presenting symptoms, size, surgical methods, and recurrence. Case presentation: A case of intramuscular lipoma occurring in tongue region in a 65-year-old male is reported. Surgical excision is the mainstay of treatment for the lesion. In order to decrease the deformity and discomfort after the excision, we tried to modify surgical technique using enveloped mucosal flap. This technique provided more comfortable healing procedure on the operative site without recurrence. Conclusion: This is a rare case of large intramuscular lipoma on tongue. Surgical excision with enveloped mucosal flap design was performed to diminish postoperative raw surface and discomfort and a 24-month follow-up showed excellent healing without any recurrence. A case of intramuscular lipoma on tongue and relevant literature reviews are presented in this study.

Recent case studies raised the possibility that cutaneous and oral mucosal manifestations may be associated with the coronavirus disease 2019 (COVID-19) vaccination. A healthy 43-year-old male presented an acute aphthous stomatitis following Moderna COVID-19 vaccination. This rare case draws attention to a potential etiologic effect for oral mucosal manifestation from COVID-19 vaccination. Further investigation to shed light on prevalence and pathophysiologic association of this oral lesion and COVID-19 vaccination deserve attention.

There are many causes of oral mucosal diseases, so accordingly, there are various treatments available. The most commonly used agents include adrenocortical hormones, antifungals, antivirals, antibacterials, and immunosuppressants. However, it must also be noted that improving oral hygiene and nutrition, and reducing stress are effective in symptom relief. Furthermore, patients with existing diseases of the oral mucosa should avoid behavior that may cause an increase in pain. Unfortunately, many patients are unaware of the activities that may lead to increased pain and therefore do not avoid these activities. The aim of this study was to investigate and analyze the behavior of patients with oral mucosal disease with regard to activities that led to increase pain. This cross-sectional study was performed on a sample of patients with oral mucosal disease selected from the Oral Medicine Clinic of the Pusan National Hospital during March to August 2013. These patients were randomly selected. From a total of 479 patients, 116 patients with mucosal disease were selected and 73 fully completed questionnaires were included in the analysis. Data were collected by using self-completed questionnaires. The results were as follows: Mean score of Question 13 (Not smoking) is $2.47{\pm}1.11$. Mean score of Question 11 (Not drinking alcohol or not using mouthwash containing alcohol) is $2.22{\pm}1.15$. The other questions resulted in scores lower than 1.5. The answers to the questions were scored according to the following assigned numerical values: not keeping = score of 0; little keeping = score of 1; often keeping = score of 2; always keeping = score of 3. In conclusion, patients with oral mucosal diseases unknowingly engage in activities that result in an increase in pain. Therefore, they need to be educated about how to behave to protect oral mucosal lesion.

The authors evaluated the distribution of the antral pathologic conditions and their radiographic features on the Waters' radiolgraphs of 151 children patients who had been radiographed at the department of Oral Radiology, Seoul National University Hospitals. The obtained results were as follows: 1. The most common pathologic condition was inflammatory change(58%). Percentage of cases showing cystic lesion and fibro-osseous lesion were 25% and 11% respectively. 2. In cases of inflammatory change, odontogenic origins were 12 cases(13%) and bilateral occurrences were 37 cases(39%). 3. The most common radiographic feature of the inflammatory conditions was various types of mucosal thickenkng(78%).Percentage of cases showing totally increased radiopacity was 18%. 4. Intrinsic cystic lesions were 26 cases(65%) and dentigerous cyst was the most common extrinsic cyst. 5. Most of the fibro-osseous lesions(15 from 17 cases) were fibrous dysplasia. 6. Maxillary sinus hypoplasia(5 cases) and Burkitt's lyphoma(4 cases) were also observed.
