Temporary reconstruction of the mandibular continuity defect resulting from the ablative tumor surgery with a reconstruction plate can be used for the preservation of normal facial contour and oral function and for periodic follow up of recurrence. Reconstruction plates are adapted to the bone before the resection and provisionally fixated with some screws. Accurate contouring and adaptation are very important for the prevention of displacement of bony stumps and decubituous skin ulcer. However, if there is large expanding buccal tumor mass in mandible, it is very difficult or even impossible to contour the plate before resection. I, therefore, introduce the reconstruction plate application technique using a simple condylar repositioning miniplate after segmental mandibular resection.

Oral leukoplakia is the most common premalignant lesion of the oral mucosa. This case report presents the effect of acupuncture on Oral leukoplakia. The 67 years old male patient who has suffered for 2 years was treated with Right side Saam acupucture Damjeonggyeok(BL66, GB43, LI1, GB44) without other treatment. Acupuncture was performed for 15 minutes. The effect of acupuncture was evaluated as photographic change and visual analog scale(VAS) of subjective symptoms in oral cavity. After 87th acupunture treatment during 226 days, Leukoplakias were decreased at the right side of ventral tongue and the left border of the tongue and the lower lip. Furthermore, ulcer, erosion at the left border of the tongue were disappeared and VAS of Burning pain in the tongue decreased from 8 to 2. Although acupuncture is unusual treatment for Oral Leukoplakia, this case report suggested the effectiveness of using Damjeonggyeok on Oral Leukoplakia according to Saam acupuncture method.

In a preliminary screening of plant extracts for the antigastritic and antiulcer actions in rats, the extracts of head of Panax ginseng Radix showed positive activity in HCl ethanol-induced gastric lesion. Among the systematic fractions of hexane, chloroform, butanol and water, the most potent butanol fraction reduced significantly HCl ethanol-induced gastric lesion at the oral dose of 500 mg/kg. In pylorus ligated rats, hexane and butanol fraction showed decreases in the volume of gastric secretion and acid output, of which effects were stronger in butanol fraction. Further assays with butanol fraction disclosed that it significantly suppressed the aspirin-induced and Shay ulcer. The butanol fraction at the intraduodenal dose of 500 mg/kg showed significant stimulation of mucus secretion.

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.

The object of this study was to observe the effect of Banhasasim-tang (BHSST) on the HCl/EtOH-induced gastric ulcer in mice. Three different dosages of BHSST extract (400, 200 and 100 mg/kg) were once orally administered 1 hr before HCl/EtOH mixture treatment. One hour after HCl/EtOH mixture single oral treatment, the changes on the gross hemorrhagic lesion scores, fundic histopathology, gastric nitrate/nitrite contents, lipid peroxidation and antioxidant defense system (catalase and superoxide dismutase (SOD) activities) were observed, and compared with that of ranitidine 100 mg/kg. As results of all three different dosages of BHSST extract treatment in the HCl/EtOH-induced gastric ulcer mice, significant and dose-dependent decreased gastric damages. BHSST extracts also increased gastric nitrate/nitrite contents and strengthened the antioxidant defense systems, and increased the activities of catalase and SOD, respectively. BHSST extracts 200 mg/kg showed similar anti-ulcerative effect as compared with ranitidine 100 mg/kg, in this experiment. BHSST has favorable protective effects against to the HCl/EtOH-induced gastric damages, through the strengthening of the body antioxidant defense systems. These gastroprotective effects of BHSST against HCl/EtOH-induced gastric ulcer considered as results of complicated synergic effects of their 8 kinds of herbal components, but exact synergic or individual herbal effects are difficult to discuss in this study. Therefore, more detail synergic effects between 8 kinds of individual herbal component of BHSST should be tested with screening of active anti-inflammatory chemical ingredients, in future.

Objectives : The purpose of this study is to report the effectiveness of korean medical treatments on recurrent aphthous stomatitis(RAS) diagnosed as excess pattern(實證) based on symptoms of damum(痰飮), blood stasis(瘀血) and fire-heat(火熱). Methods : We treated a 61-year-old male patient who has RAS by korean medicine, pharmacopuncture and acupuncture treatment. These treatments were performed from 2020.01.22. to 2020.02.29. We have confirmed the improvement of ulcer lesions and pain. We recorded images that include change of symptoms. Results : After the treatments were done, the scores of numeric rating scale(NRS), oral health impact profile-14 (OHIP-14), oral assessment guide (OAG) and world health organization oral toxicity scale (WHO OTS) were decreased. The NRS score was decreased from 7 to 1. The OHIP-14 score was decreased from 30 to 14. The OAG score was decreased from 17 to 9. The WHO OTS score was decreased from 2 to 1. And ulcer lesions were clearly decreased. Conclusions : According to the result, korean medical treatments such as korean medicine, pharmacopuncture and acupuncture treatment, that are targeted at excess pattern(實證) caused by damum(痰飮), blood stasis(瘀血) and fire-heat(火熱) can be effective for the treatment of RAS.

Primary intraosseous carcinoma (PIOC) is a rare odontogenic carcinoma defined as a squamous cell carcinoma arising within a jaw having no initial connection with the oral mucosa, and probably developing from residues of the odontogenic epithelium. PIOC appears more common in male than female, especially at posterior portion of the mandible. Radiographic features of PIOC show irregular patterns of bone destruction with ill defined margins. It could be sometimes misdiagnosed as the cyst or benign tumor because it shows well defined margins. If it couldn't be done appropriate treatment initially, PIOC shows extremely aggressive involvement, extensive local destruction and spreads to the overlying soft tissue. Therefore accurate diagnosis in early state is necessary. The diagnosis criteria proposed for PIOC are : (1) absence of ulcer formation, except when caused by other factors, (2) histologic evidence of squamous cell carcinoma without a cystic component or other odontogenic tumor cell, and (3) absence of another primary tumor on chest radiograph obtained at the time of diagnosis and during a follow-up period of more than 6 month(Suei et al., 1994).

The aim of this study was to investigate the frequency of positive patch test reaction to dental materials in patients with oral mucosal diseases. Epicutaneous patch test was performed in 110 patients with oral mucosal diseases; 41 patients with oral lichen planus(OLP), 44 patients with burning mouth syndrome(BMS), 25 patients with other oral mucosal diseases including recurrent aphthous ulcer and mucous membrane pemphigoid. The obtained results were as follows: Oral gold restorations were most common in patents with oral mucosal diseases and porcelain fused metal crown, implant appeared in the order. 33 of 110 patients did not appear skin reactions (negative, 30%) and 77 patients (positive, 70%) had skin reactions including redness, rash, blisters. Dental materials causing positive reaction to patch test were mainly as gold-sodium-thiosulfate (26.7%), nickel sulfate(Ni) (22.7%), cobalt chloride(Co) (14.7%), palladium chloride(Pd) (11.9%), potassium dichromate (10.7%) in order, respectively. In conclusion, old metal restorations could be the cause of oral mucosal diseases and epicutaneous patch test could be used as a tool to improve the oral conditions.

Objectives: This study aimed to assess the level of knowledge of oral cancer and its associated factors among university students in Malaysia. Methods: A cross sectional study was conducted among 200 university students in Malaysia. A self administered questionnaire was used to collect data. It included questions on sociodemographic data, awareness and knowledge of oral cancer. Results: Mean age of the respondents was $21.5{\pm}2.5$ and the age ranged from 18 to 27 years. The majority of the respondents were aware of oral cancer (92.0%) and recognized the followings as signs and symptoms of oral cancer: ulcer and oral bleeding (71.0%), followed by swelling (61.5%). A satisfactory knowledge was observed on the following risk factors; smoking (95.5%), poor oral hygiene (90.5%), family history (90.0%), alcohol (84.5%) and poor fitting dentures (83.0%). However, unsatisfactory knowledge was observed about hot/spicy food (46.5%), obesity (36.0%), old age (31.5%), dietary factor (29.0%) and smokeless tobacco (25.5%). Knowledge of oral cancer was associated significantly with age (p<0.01), year of study (p<0.01) and course of study (p<0.01). Conclusion: Instead of satisfactory awareness and knowledge of oral cancer and its clinical presentations, inadequate knowledge was observed about its risk factors. There is a need to introduce oral cancer education among university students.
