Irritation fibroma is a common hyperplastic lesion of the oral mucosa that can occur in response to chronic irritation or trauma. This report presents an unusual case of irritation fibroma associated with ectopic eruption of the maxillary left central incisor in a patient with Angelman syndrome. Considering the patient's medical history and cooperative ability, excisional biopsy under intramuscular sedation using midazolam was performed. The patient exhibited successful healing without lesion recurrence. It is important to perform histopathological examination followed by excisional biopsy, because other benign or malignant tumors may mimic the clinical appearance of an irritation fibroma.

Introduction : Oral motor function is basic function of sensory exploration, feeding, and communication, that develops from the fetal stage to childhood. Problems with oral motor function result in difficulty within handling food in the oral cavity, decreased swallowing and feeding skills, difficulty with communication, and problems with oral hygiene. To treat these symptoms, oral motor therapy is provided for normalizing sensory adaptation in the oral cavity, and increasing postural control, oral movement and oral motor function. Discussion : The oral motor facilitation technique (OMFT) was developed for increasing general and integrated oral motor function based on the following: 1) understanding orofacial muscular physiology; 2) a comprehensive approach to sensory·adaptation·behavior·cognition; 3) sensorimotor stimulation by a manual approach; 4) motor control and motor learning theory. The OMFT is a new evidence-based treatment protocol, for children and adults with neuromuscular and oral motor problems. Conclusion : The goal of this article is to provide a theoretical background for OMFT development and the basic concept for the clinical application of OMFT. We hope that this article will help oral motor therapy experts to provide effective therapy in a more professional way.

저수준레이저조사 (low level lser irradiation, LLLI) 가 골형성을 자극한다고 보고되고 있지만 골아세포기능에 있어서 어떠한 역할을 하는지 별로 밝혀진 바가 없다. 본 연구에서는 백서 두 개관 조골세포양 세포(ROB)와 백서 조골세포주(ROS17/2.8)에 대한 저수준레이저의 효과를 조사하기 위하여 세포증식, alkaline phosphatase activity, 석회화 결질형성등을 관찰하였다. 두가지 배양 세포군에 저수준레이저를 조사한 결과 저수준레이저가 alkaline phosphatase activity를 증가시킬 뿐만 아니라 석회화 결절의 형성을 촉진하는 것을 볼 수 있었다. 이러한 결과로 보아 저수준레이저는 조골세포의 기능과 무기질침착을 자극함으로써 골형성을 촉진한다고 추정된다.

Introduction : OMFT is a therapeutic technique based on sensorimotor, motor control and motor learning, and its major goal is to improve oral motor function. The oral motor conceptual hierarchical development is divided into 5 steps: 1) sensorimotor, 2) movement integration, 3) structural movement, 4) functional oral motor, and 5) comprehensive oral motor. Discussion : The OMFT consists of 3 techniques, 10 categories, and 50 sub-item. 1) Warming up technique: 2 categories, 12 sub-item, warming up by sensory awareness and adaptation, therapy situation adaptation, neck movement; 2) Key point technique: 7 categories, 30 sub-item, oral motor facilitation and increasing chewing skill by direct stroke of oral structures such as the face, lips, cheeks, gum, jaws, and tongue; 3) Application technique: 1 category, 8 sub-item, facilitate food intake and swallowing. Conclusion : The goal of this article is to introduce 3 techniques, 50 sub-item of OMFT, as a comprehensive oral motor therapy method, for application to clients. This article provides information that will help oral motor specialists in treating clients with oral motor problems more effectively and professionally.

Xerostomia is subjective feeling of dry mouth, a symptom that may or may not be accompanied by hyposalivation, an objective decrease in salivary flow. There are many causes induced xerostomia like drugs, salivary gland diseases, radiation therapy to the head and neck region, Sjogren syndrome, emotional stress etc. Insufficient salivary flow creates complications with oral candidiasis, dental caries, periodontitis, halitosis, dysgeusia. So finally, these complications lead to an overall decline in quality of life. Managements of xerostomia are eliminating or alterating the etiologic factors, relieving symptoms, preventing or correcting the consequences of salivary dysfunction, treating underlying disease and stimulating salivation. One of the salivation stimulation agents studied to treat xerostomia was the pilocarpine muscarinic agonist. Pilocarpine is one of salivation stimulants, a parasympathomimetic drug and non-selective muscarinic receptor agonist. Systemic pilocarpine has been used to stimulate salivary secretion. But systemic administration of pilocarpine has limitations such as increased risk of side effects and contraindications. Side effects of systemic pilocarpine administration are sweating, urinary and gastrointestinal disturbance, risk of cardiovascular and pulmonary disorders. This drug must be used carefully by patients with controlled asthma, chronic bronchitis, pulmonary or cardiac disease. Patient with acute asthma, narrow angle glaucoma, iritis should not use pilocarpine. Like this, systemic pilocarpine has many limitations. So, many investigators also have looked at the effectiveness of topical pilocarpine. Here we present patients with xerostomia which was relieved by pilocarpine mouthwash.

치과용 인상재는 구강내에서 치아나 주위조직을 정확히 인기하여야 하며 조작이 간편하고 유동성이 충분하며 경화시간이 적당하고 값도 저렴해야 한다. 또 구강내에서 제거할 때 영구변형이나 파절되지 않는 충분한 강도와 크기의 정확성도 있어야 하며 자극이나 독성이 없고 인체에 안정성이 있고 모형재와 친화성이 있으며 보관중에도 변질해서는 안된다. 그러나 인상재는 서로 상이한 특성이 있고 장단점이 각각 다르므로 모든 조건에 일치하는 인상재는 거의 없다. 따라서 여러 인상재중에서 가장 적합한 인상재를 선택하는 것이 중요한 과정이다. 즉 인상재의 특성과 응용을 알고 선택할땐 보다 정밀한 모형을 얻을 수 있다. 기록에 의하면 18~19세기경에 최초로 인상용 왁스를 사용한 이래 19세기 중엽에 인상용 석고, 1925년에 agar, 1930년 ZOE, 1945년 앨지네이트, 1957년 실리콘, 1967년 polyether 및 1975년 부가중합형 실리콘이 사용되었으며 인상재가 유연성과 탄성이 있는가 경고하며 비탄성인가 또는 온도변화와 화학반응으로 경화되는 가에 따라서 ZOE paste, 인상용 석고, 인상용 왁스, 인상용 콤파운드, 수성콜로이드(agar, 앨지네이트), polysulfide, 실리콘(축중합형, 부가중합형) 및 polyether 인상재등 10여종으로 분류된다.

Intraoral soft tissue can easily be injured by weak mechanical irritation. Each symptom by irritation is various, but most of patients show chronic inflammatory lesion. The fibroma is the most frequent disease found in intraoral area followed by pyogenic granuloma, epulis fissuratum, palatal papillomatosis, and epulis granulomatosum. The inflammatory hyperplasia by mechnical irritation is easily different from other disease, but this shows similar to several benign and malignant tumors required differential diagnosis. By microscopic feature, the lesions is divided by granulatory stage, mixed stage, and fibrotic tissue stage. The inflammatory hyperplasia is differently treated by each clinical features.: only removal of cause or, and excisional biopsy is/are required. This is the cases report of reactive hyperplasia of intraoral soft tissue by mechanical irritation that suggests various treatments of each cases.

폐는 산소가 많이 포함된 신선한 공기를 혈액에 공급하여 줌으로써 우리 몸의 활동유지에 필요한 산소를 공급해 줌과 동시에 신체의 활동에 의하여 생성된 이산화탄소를 몸밖으로 배출하는 작용을 주로 하는 기관이다. 따라서 폐는 본연의 기능을 유지하기 위하여 계속적으로 외부의 공기를 흡입하여야 한다. 이 과정에서 외부에서 균으로 오염된 공기를 흡인하거나 또는 폐에 도달되기 전에 공기가 거쳐 지나가게 되는 구강 및 인후가 균으로 오염되어 있다가 오염된 분비물이 기도로 흡인되거나 하는 경우에는 폐실질에 염증이 발생할 수 잇는데, 이러한 경우를 폐렴이라고 한다. 이밖에도 다른 외부장기의 감염이 혈행성으로 폐로 전이되어서 폐렴이 발생할 수도 있다. 폐렴의 원인균은 각종 세균, mycoplasma, chlamidae, rickettsiae, virus 등 매우 다양하며, 균이 아닌 자극성 물질 또 호산구의 폐침윤 등에 의해서도 폐렴이 발생할 수 있다.

최근 많은 연구자들에 의해 고분자재료를 이용하여 약물의 방출속도를 조절하며 이를 통해서 장기간에 걸쳐 치료 유효농도이상의 혈중농도를 유지함으로써 치료효과를 극대화 하려는 연구가 진행되고 있다. 특히 고분자 재료를 이용한 macromolecular drug의 방출조절에 관한 연구가 활발히 진행되고 있다. macromolercular durg은 인슐린, 알부민등의 단백질과 유로키나제등의 효소와 같이 약효는 매우 높으나 적절한 투여 수단이 발견ㄷ되지 않아 투여가 매우 번거로운 단점을 가지고 있다. 이와같은 macromolercular durg의 대부분은 구강을 통해서 투여하는 것은 거의 불가능하며 체내 반감기도 매우 짧아서 적절한 투여 방법의 개선이 필요하다.

$T4K^{TM}$(Myofunctional Research Co, Australia) is one of the myofunctional appliance developed to be used in children of mixed dentition. Myofuncitonal appliance stimulate the facial, masticatory and tongue muscle and help to balance the muscular force. Labial bow included in the device exerts strength in excessively labial inclineded upper jaw, Lip bumper blocks strength of the mouth to prevent abnormal strength exerted in lower jaw, Tongue tag secures proper position of tongue, and additional exercise is not required for child patients. For the more, simpler design and softer texture of device prmoted cooperation of patients during use. This case report is to present the satisfactory results gained by using $T4K^{TM}$ on Class II patients. Comment 1. $T4K^{TM}$ was applied in Class II malocclusion patients of mixed dentition with expected space insufficient to gain facial improvement. 2. Excessive overjet, overbite were improved. 3. Main effects are regarded to have been achieved by development of lingual slant of upper jaw, labial slant of lower jaw, and lower part of jawbone. 4. Bad habits, such as mouth breathing, can also be adjusted.
