A common method for treating oral mucosal diseases is taking medication by oral administration. The oral administration is the method of least resistance. Because large part of drugs is degraded by liver, it is necessary to take more drugs getting to appropriate level in blood stream. And there are so many side effects when patients take drugs by oral administration. In so many cases, the patients who suffer from oral mucosal problems have the other general diseases simultaneously. Willingly or not, some patients can't take the medicine by oral administration. Number of topical drugs for oral mucosal disease is less than that for skin diseases because the environment of oral mucosa prevents activity of medicine. In this paper, research on effects of topical type medication for treating oral mucosal diseases is conducted through investigating currently used medications and their effects. In addition, effects of dissolved oral medications with appropriate solvent are demonstrated if this medication is useful for patients clinically.

Dendroaspis natriuretic peptide (DNP), a fourth member of the natriuretic peptide isolated from the venom of the Dendroaspis angusticeps snake, has been reported to be present in human plasma and atrial myocardium and caused vasorelaxation and diuresis in experimental animals. However, it is uncertain whether they are present in peripheral organs other than the heart and its further physiological roles also remains to be clarified. To assess the possible physiological role of DNP in the salivary glands, I investigated the localization of DNP peptide in the rat salivary glands by immunohistochemistry and the binding sites for radiolabelled DNP in the rat salivary glands and oral mucosa using in vitro autoradiography. DNP immunoreactivity was widely distributed in the submandibular, sublingual and parotid glands, particularly in the ducts such as the intercalated and striated ducts, where atrial natriuretic peptide (ANP) was colocalized in consecutive sections, but not in acini. High density $^{125}I-DNP$ binding sites were localized in the epithelia of the tongue and hard palate, while low density binding sites for $^{125}I-DNP$ were also distributed in the submandibular, sublingual, and parotid glands. In the hard palate and tongue, the precise location of this binding was revealed on the basal and parabasal cells of the epithelia by emulsion microautoradiography. These results suggest that DNP may not only have a role in the salivary glands but also play a role in the regulation of growth in the oral epithelium, particularly in the hard palate and tongue.

상악과 하악이 선천적으로 붙어서 태어나는 선천성 유합증은 드문 선천성 기형으로 단순히 점막이 붙은 점막유합증에서 악골이 붙은 골유합증까지 다양하게 나타난다. 이중 상악골과 하악골의 골자체가 붙는 골유합증은 아주 드물어서 현재까지 26증례만 보고되고 있는데, 보고된 대부분의 증례는 편측에만 발생하는 불완전형으로 알려져 있다. 7세 된 여아환자가 인디아의 GSR 병원에 입이 벌어지지 않는다는 주소로 내원하였는데 환아의 턱은 완전히 움직이지 않았으며, 2-3 mm 정도 벌어지는 앞니부위에서는 2.5 cm 폭경의 3.0 mm 두께의 단단한 치조점막이 관찰되었다. 전기메스로 전방부의 부착성 섬유밴드를 잘라준 후 즉각적인 개구정도는 16 mm 정도까지 가능하여 구강으로의 기관삽관이 가능하였다. 삽관후 양쪽 후방부 협측점막의 두꺼운 밴드들을 모두 제거하여 개구량을 33 mm까지 증진시킨 후 수술을 종결하였다. 환아의 보호자에게 거즈 블록과 설압자를 이용하여 개구 연습을 능동적으로 시키도록 강조하여 교육하였으며 술후 16개월 경과시까지 특별한 합병증이나 개구량 감소는 관찰되지 않았다. 독립적으로 발생한 선천성 치조점막 유합증 환자에서 비정상적으로 커져있는 과두와 설골이 관찰되었는데, 설-하악 구조의 비정상적인 발육에 기인하여 지속적인 비정상적 운동으로 인한 이차적인 치은과 협점막의 섬유성 부착이 생긴 것으로 추측되었다. 이에 마취과와의 효율적인 협진으로 기관절개술 등의 부가적인 마취방법 없이 효과적으로 치료할 수 있었다.

Helicobacter pylori (H. pylori) is bacterial infection, with more than half of the world population infected and relates to many oral disease such oral lichen planus, recurrent aphthous ulceration, periodontal disease and halitosis and so on. Burning mouth syndrome(BMS) is defined as a burning sensation of the oral mucosa, lips, and/or tongue, in the absence of specific oral lesions. The etiology of BMS is suggested local, systemic and psychological factors and researchs related BMS and to infection of H. pyloir in the oral cavity are few. The purpose of this study was to evaluate relationship between burning mouth syndrome and H. pylori in the oral cavity. We recruited 21 subjects with burning mouth syndrome and 21 subjects as control group. Samples in the oral cavity were taken area of buccal mucosa, dorsum of the tongue and saliva. We analysed samples by nested polymerase chain reaction(PCR). The results were as follows: 1. Among 21 patients with burning mouth sydrome and 21 subjects of control group, 6(29%) and 3(14%) were positive respectively(P>0.05). 2. In detection rate of H. pylori in area taken sample, 3(14%), 2(10%) and 4(19%) were positive in buccal mucosa, dorsum of the tongue and saliva of patient and 2(10%) and 1(5%) were positive in dorsum of the tongue and saliva of control group(P>0.05). Conclusively, we can guess that H. pylori in the oral cavity is not related with burning mouth syndrome.

Epidermoid cysts can be found anywhere in the body, particularly in areas where embryonic elements fuse together. Most cases have been reported in the ovaries, the testicles, as well as the hand and feet. Epidermoid cysts in mouth are uncommon and account for less than 0.01% of all oral cysts. The treatment of choice is complete surgical excision and prognosis is excellent. The purpose of this article is to describe two cases of an epidermoid cyst in the oral cavity mucosa and a review of the literature.

This study attempted to identify the entrance exam stress levels in high school students and analyze the relationship this entrance exam stress and perceived oral health status. Self-administered survey was conducted in total 304 students attending in academic high schools in Bucheon. For analysis, SPSS was used to perform t-test and one-way ANOVA. As a result of the study, the entrance exam stress level of academic high school students was 2.71. The level of sub-factors were that tension for exam/poor result was highest by 3.08 and the next were future uncertainty (2.81), parents pressure (2.56), and insufficient free time (2.52). The group with high entrance exam stress showed significantly high perceived degrees of temporomandibular disorder, oral mucosal disease and xerostama. Among sub-factors of stress, the group with high tension for exam/poor result stress had significantly high perceived degrees of dental caries, teporomandibular disorder, oral mucosal disease and xerostama. Because perception on oral health issues increased with high entrance exam stress in high school students, it is necessary to seek some ways to decrease oral health problems even though entrance exam stress is intensified. To do so, it is inferred that it will be very important to promote oral health education to develop ability of high school students to practice correct oral management method.

Isolation and primary culture technique of rabbit oral keratinocytes, and the study for effect of environmental factors on the cell growth were carried out in T75-flask. $1.92{\pm}0.59{\times}10^6$ viable cells were isolated by trypsin enzymatic digestion method from $0.25cm^2$ biopsy of rabbit oral mucosa. Primary culture with 10 mL of K-SFM containing 50 mg/L BPE, $5.0{\mu}g/L$ EGF and 0.15 mM $Ca^{2+}$ showed confluence after 8 days and doubling time was 2.54 days. Effect of medium types, medium volume and supplement types on the cell growth was investigated after the cultured keratinocytes had been harvested from primary confluence. Serum addition showed adverse effect and the increase of serum concentration didn't have an effect on the cell growth. The increase of medium volume decreased the cell growth. The increase of calcium concentration increased the cell growth and 2.0 mM was optimum value. In conclusion, when rabbit oral keratinocytes was cultured in T75-flask, the most effective conditions was to use 10 mL of K-SFM containing 50 mg/L BPE, $5.0{\mu}g/L$ EGF and 2.0 mM $Ca^{2+}$, and doubling time was 1.32 days. This study can provide the useful informations to develop a process and design a bioreactor for the culture of keratinocytes in human body like skin and cornea, as well as mucosa.

국소적 소인에 의한 구강내 출혈은 구소적 감염이나 원인 혹은 외상등에 의해 야기되는 것으로 혈액응고에 관여하는 여러인자의 양적, 질적 이상으로 유발되는 출혈성 소인에 의한 출혈과는 구별되어 진다. 대부분의 치과의사가 접할 수 있는 가장 흔한 출혈은 국소적 소인에 의한 것이며, 명심해야 될 사항은 이런 국소적 소인에 전신적 출혈성 소인의 한 요소일 수도 있다는 점이다. 이에 치과의사들은 구강내에서 국소적 원인을 쉽게 발견 치료할 수도 있으나, 전신적 출혈성 소인에 대한 연관성 조사를 항시 염두에 두어야 하겠다. 출혈성 소인에 의한 출혈은 특별한 외상 없이도 되부, 점막, 관절등에 자연히 출혈이 일어나며, 가벼운 외상에 의해서도 쉽게 출혈하는 경향이 있는 점이 국소적 소인에 의한 출혈과의 감별사항이다. 가장 관찰하기 쉬운 곳이 피부 및 점막으로 출혈하여 피가 모인 것을 자반(Purpura)이라 하며, 크기 및 정도에 따라 모세혈관에서의 출혈은 점상출혈(Petechia), 세동맥 및 세정맥에서의 출혈은 반상출혈(Ecchymosis), 좀더 심부에서 출혈하여 촉지되는 혈종(Hematoma)으로 나눌 수 있다. 임상적으로 구별되는 이런 양상을 잘 관찰하고 주의해야 하겠다.

Burning mouth syndrome (BMS) is defined as burning pain in the tongue or other oral mucous membrane associated with normal sign and laboratory findings at least 4 to 6 months. There are many factors that affect this condition and the pain characters are various among the sufferers, so it is difficult to diagnose exactly and treat properly. The cause of BMS is currently unknown. The etiology is presumed to be that it is related with local, systemic and psychogenic factor. The BMS is related with local factor such as allergic reaction, oral fungal infection(candidiasis), parafunctional oral habits and systemic factors such as diabetes mellitus, hypothyroidism, nutritional deficiencies(vitamin $B_{12}$, folic acid), hyposalivation and psychogenic factor such as depression, anxiety, cancerphobia. So clinicians must be aware of these factors and can give proper treatment options to patients. The management of BMS are pharmacologic management, cognitive behavioral therapy and psychotherapy treatment. Clonazepam, gabapentin, amitriptyline, alpha-lipoic acid and capsaicin are used to manage the BMS. Among these, topical clonazepam is reported that the effect is higher than systemic medication and the complications are rare. This case report is about some cases of the effect of topical clonazepam on BMS.
