A wide variety of benign and malignant lesions and other diseases can develop on oral mucosa. Oral mucosal lesions can also be associated with an underlying systemic disease, so their correct diagnosis, which may even share similar clinical and demographic features, is always a challenge for a dentist. Common oral mucosal lesions include candidiasis, herpes viral infection, leukoplakia, recurrent aphthous stomatitis, pemphigus, lichen planus and benign migratory glossitis. The differential diagnosis of these lesions are based on a thorough review of the patient's past medical and dental history and a complete oral examination. The knowledge of clinical features such as size, location, morphology, color, and pain is helpful in establishing a diagnosis. In addition, diagnostic tests, including microbiologic and laboratory tests and biopsies are usually required for establishing a proper diagnosis.

The purpose of this study is to provide basic data for the oral health and obesity management of adults by grasping the relationship between obesity and oral health. Among the patients who visited the dental clinic, 229 patients who agreed to fill out questionnaires were analyzed by self - filling questionnaire. Body mass index and waist circumference were used for the study of obesity. Body mass index and poor periodontal health status were significantly higher(33.3%) and abdominal obesity and poor periodontal health status were 10.9%.Abdominal obesity was significantly higher(28.6%) in the group with less than 20 teeth. Body mass index and abdominal obesity were higher in body pain, psychological discomfort, physical abilities, psychological abilities, social disadvantage, and oral health than in normal subjects. As a result of correlation analysis with obesity index, it was found that the more period of obesity, the more periodontal disease and mucosal state related symptoms appeared(p<0.05). Therefore, in order to solve health problems such as obesity, it is necessary to recognize the importance of oral health and to make efforts to induce positive oral health behavior.

The authors observed the ultrastructure of oral leukoplakia simplex of gingiva, buccal mucosa, tongue and alveolar ridge. For the purpose of clearly defining the lesions under investigation in this study, leukoplakias were cinsidered to be any white patches on the oral mucous membranes that could not be removed by rubbing and could not be classified clinically or microscopically as another diagnosable disease. The tissue to be examined were embedded in paraffin for light microscopic study. The tissue to be examined under the electronomicroscope were fixed in 2.5% glutaraldehyde in 0.1M cacodylate buffer and 1% osmic acid in 0.1M cacodylate buffer, dehydrated with guaded alchol, and treated with propylene oxide, and embedded in Epon.Ultrathin sections were obtained by LKB III ultrotome, stained with uranyl acetate/lead citrate, and examined with Corinth 500EM. The results were as follows : 1. Epithelium of leukoplakia consisted of stratum basale, stratum spinosum, stratum granulosum and stratum corneum. 2. There was hyperorthokerotosis or hyperparakeratosis. 3. Granular cells contained a lot number of membrane coating granule showing lamellar structure, clearing ot codensation, and a lot of keratohyaline granule varied in size. 4. An increased concentration of tonofilaments and an increased number of desmosomes were found in the stratum spinosum. 5. Basal lamina generally showed its continuity, but in some locatoins, its interreption and multiplication appeared.

The purpose of this study was to examine the occupational risk factors that affect oral symptoms in hospital facility workers. This study surveyed 627 hospital facility temp·contract workers in the metropolitan area from November 17, 2020 to May 20, 2021. The results of the study indicate that oral symptoms were higher among workers with high risk of musculoskeletal disorders and injuries. Also, symptoms of oral mucosa, temporomandibular joint disorder, and dry mouth were high in the areas of job insecurity and organizational injustice. As the occupational risk factors and occupational stress of workers increased, the risk of oral symptoms increased. In the future, this study can be used as basic data for improving oral health policies to better the oral health of hospital facility workers.

Hereditary hemorrhagic telangiectasia is a rare autosomal dorminant disease that features abnormal and fragile vascular dilations of terminal vessels in skin and mucous membranes, as well as arteriovenous malformations of internal organs, particularly lungs, brain, and liver. Often patients have not been diagnosed with HHT for a long time, and undiagnosed HHT patients unnecessarily develop serious complications such as severe life-threatening hemorrhage, stroke or brain abscess. Therefore, early detection and appropriate screening is very important. Early detection of HHT allows the appropriate screening for the presence of silent disease such as AVMs in the lungs, liver, or brain, and preventive treatment in the patient and their affected family members. Dentists should be familiar with HHT because the telangiectases on skin and oral mucosa are often the most dramatic and most easily identified component of HHT. Recently, we experienced a case of HHT. We present the case with a review of the literature.

In currently, stress diseases are increased that present several sign and symptoms. Under stress condition, there are dry mouth, burning mouth syndrome, oral mucosa diseases and halitosis more frequently. Changing of salivary proportion is checked in almost patients with changing of function and structure in salivary gland. This study purpose are what effect stress does on salivary gland, and a-amylase on salivary gland. This study was resulted that 1. Under restraint stress, acinar cells are vacuolization and changing of intercellular spaces are separated, and peripheral tissues of duct are changed 2. Acinar cells were shrunk after 3 hours under restraint stress, intercellular space was separated after 6hours, peripheral tissues of duct started to change after 72 hours, and acinar cells and peripheral tissues of duct were all severely changed after 168hours. 3. In immunohistochemical study, amylase reaction was showed partially and irregularly after 3 hours, was getting little milder after 6 hours. And amylase reaction was gradually increased from the time of 12 hours after experiment up to the time of 48 hours after experiment. But after 168 hours, amylase appearance was diminished. According this result, emotional stress can change of salivary gland structure, and amylase secretion, the important digestive enzyme from salivary gland is changed and it is supposed to make digestive disorder and to make halitosis efficiency. So, we need to study about secretion of amylase.

After tooth extraction, alveolar bone is resorbed over time. Loss of alveolar bone and reduction of upper soft tissue poses difficulties in future implant placement and long-term survival of the implant. This case report focuses on increasing the soft and hard tissues at the implant placement site by using alveolar ridge augmentation and a xenogeneic collagen matrix as a soft tissue substitute in an extraction socket affected by periodontal disease. In each case, the width of the alveolar bone increased to 6 mm, 8 mm, and 4 mm, and regeneration of the interdental papilla around the implant was shown, as well as buccal keratinized gingiva of 4 mm, 6 mm, and 4 mm, respectively. Enlarged alveolar bone facilitates implant surgery, and interdental papillae and keratinized gingiva enable aesthetic prosthesis. This study performed alveolar ridge augmentation on patients with extraction sockets affected by periodontal disease and additionally used soft tissue substitutes to provide a better environment for implant placement and have positive effects for aesthetic and predictive implant surgery.

Erythema multiforme (EM) is an acute mucocutaneous disorder involving the skin, mouth, eyes, and genital organs. It is classified into EM minor and EM major according to the involvement of the mucosal membrane. Stevens-Johnson syndrome (SJS) and toxic epidermal necrosis (TEN) belong to EM major. Compared to EM minor, SJS presents with more severe and progressive symptoms, and has a higher mortality rate. Corticosteroids are used in the treatment of EM. We report three cases of EM (two cases of EM minor and one case of SJS) that developed during treatment with oral corticosteroid (deflazacort; $Calcort^{(R)}$) in children with nephrotic syndrome.
