  • Correct occlusal relationships are part of the successful prosthetic treatment for edentulous patients. Fabrication of complete dentures comprises of clinical and laboratory procedures that should be executed accurately for achieving success with fabricated dentures. Errors occurring during the clinical and laboratory procedures of a denture may subsequently lead to the occlusal errors in the final prosthesis. These occlusal errors can be corrected in two ways: i) in patient's mouth ii) by recording new centric relation and remounting dentures on an articulator. The latter method is more feasible because the mobility of denture base on the mucosa in oral cavity does not permit the identification of premature contacts in centric occlusion and tooth guided eccentric excursions. This article describes a modest and effective clinical chair-side remount procedure using customized mounting platforms.

  • 이 연구의 목적은 도포마취제로서 5% EMLA cream과 20% Benzocaine gel의 구강 내 주사침 자입 및 마취제 주입시 전/구치부 전정부와 구개부에서의 작용시간과 동통 감소 효과를 평가하기 위함이다. 두 가지 도포마취제는 양측성 무작위 단일 맹검법 분할 디자인으로 평가되었다. Phase I은 전/구치부 전정부와 구개부에 도포마취제를 도포한 후 각각의 도포마취제의 작용시간을 평가하였다. Phase II는 Phase I에서 측정된 시간을 기초로 각각의 도포마취제를 부위별로 적용하여 주사침 자입 및 마취제 주입시 동통 감소 효과를 평가하였다. 평가를 위해 100-mm modified visual analog scale(VAS)를 이용하여 주관적인 동통 수치를 기록하였고, 맥박산소측정기(Pulse oximeter)를 사용하여 주사침 자입 및 마취제 주입 전후의 맥박수를 관찰하여 객관적인 동통 감소 효과를 비교하였다. Phase I 실험결과 두 가지 도포마취제는 전치부가 구치부보다, 구개부가 전정부보다 더 긴 작용시간을 보였다. 전치부 구개부를 제외한 모든 부위에서 EMLA cream이 Benzocaine gel보다 더 빠른 작용시간을 보였다. Phase II 실험결과 마취제주입시 부위별 그룹에 따른 VAS Score를 보면 전치부와 구치부 구개부에서 EMLA cream이 Benzocaine보다 동통 감소 효과에 있어 유의한 차이를 보였다(p<.05). 결론적으로 EMLA cream은 Benzocaine보다 전정부와 구개부 모두에서 빠른 작용시간과 더 좋은 유지력을 나타냈다. 또한 EMLA cream은 Benzocaine보다 주사침 자입시 전치부 구개부를 제외한 모든 부위에서, 마취제 주입시 전치부와 구치부 구개부에서 Benzocain 에 비해 더 좋은 동통 감소 효과를 보였다.

  • The authors analyzed retrospectively the 36 patients with malignant salivary gland tumors who were treated at Department of Oral and Maxillofacial Surgery, Pusan National University Hospital from February, 1989 to September, 1997. The results obtained were as follows: 1. There were 14 males(38.9%) and 22 females(61.1%). The peak age of patients with major salivary gland tumors was the 6th decade, but with minor salivary gland was the 5th decade. 2. Of all salivary gland tumors, 5 cases arose in the parotid glands, 2 cases in the submanibular glands, 1 case in the sublingual gland and 28 cases in the minor salivary glands. 3. The incidence according to the anatomic primary site for minor salivary glands was 15 cases in the palate, 5 in the floor of mouth and 2 cases each arising in the tongue, lip, retromolar area and buccal mucosa. 4. Of all salivary gland tumors, adenoid cystic carcinoma was 5 cases in the major salivary glands and 8 in the minor salivary glands. mucoepidermoid carcinoma was 2 cases in the major salivary glands and 14 in the minor salivary glands and others were 2 cases of adenocarcinoma, 4 malignant mixed tumors and 1 undifferentiated carcinoma. 5. The incidence of cervical lymph node metastasis was 100%(2/2) in the submandibular glands, 80%(4/5) in the floor of mouth, 50%(1/2) in the tongue and 20%(1/5) in the parotid glands. The highest incidence of lymph node metastasis according to histopathological classfication was found in the high grade of mucoepidermoid carcinoma and tubular type of adenoid cystic carcinoma. 6. Nerve invasion was common in the adenoid cystic carcinoma. 7. The lung was the commonest site for distant metastasis comprising 7 cases among 7 cases in which distant spread occurred.

  • A 5-year-old Thoroughbred race horse was presented to Busan Korea Racing Authority equine hospital with a 3-year history of a slow-growing left rostral maxillary mass. The location and progressive growth of the mass eventually resulted in poor food prehension, quidding and mouth bit placement. The mass was solitary and hard, and covered by normal smooth oral mucosa. Radiographic examination of the maxillae showed a flocculated and mixed radiolucent lesion protruding outward and displacing the 202 and 203 teeth caudally. The 202 tooth was in normal size and the 203 tooth was hypoplastic on radiography. Under general anesthesia, a partial surgical resection of the mass was performed to minimize functional loss and facilitate prompt return to track. After surgery, there was improvement in food intake, mouth bit placement, and cosmetic appearance. Histopathological examination determined the resected maxillay mass to be an ossifying fibroma. However, there was continued growth of remnant mass in the maxilla. Equine ossifying fibroma is a rare condition and primarily affects the rostral mandible, and less commonly, the maxillae. In this case, the lesion was slow-growing, and caused cosmetic and functional impairments, including poor food intake and reduced trainability. Surgical resection was performed, but the effect of treatment was limited due to advanced size / stage of the tumor. Early dental care is suggested for horse owners to prevent belated identification and improve successful treatment of oral disorders like ossifying fibroma.

  • Background: The objective of this study was to report the types and relative frequency of oral malignancies and precancer in the Jazan region of Saudi Arabia during the period 2009-2014. Materials and Methods: Pathology reports were retrieved from the archives of Histopathology Department, King Fahd hospital in Jazan. Demographic data on tobacco habits, clinical presentation and histologic grading of oral precancer and cancer cases were transcribed from the files. Results: 303 (42.7%) oral pre-malignant and malignant cases were found out of 714 oral biopsy lesions. A pathology diagnosis of squamous cell carcinoma (85.1%) was most frequent, followed by premalignant lesions/epithelial dysplasia (8.6%), verrucous carcinoma (3.3%) and malignancy of other histological types (3%) such as ameloblastic carcinoma, salivary gland malignancy and sarcomas. Oral squamous cell carcinoma was predominant in females with a male to female ratio of 1:1.9. Patient age ranged from 22 to 100 years with a mean of $65{\pm}13.9$. Almost 44.6% of oral cancer had occurred after 65 years of age. Only 16.3% cases were reported in patients younger than 50 years, predominantly females. The majority of female patients had the habit of using shammah with a long duration of usage for more than 45 years. Buccoalveolar mucosa (52.3%) was the common site of involvement followed by tongue/floor of the mouth (47.7%) and clinically presented mostly as ulceration/swelling clinically. Moderately differentiated tumours (53.9%) were common followed by well differentiated (32.2%) and poorly differentiated tumours (5.8%). The prevalence of oral verrucous carcinoma (3.3%) was comparatively low with an equal distribution in both males and females. Both bucco-alveolar mucosa and tongue were predominantly affected. Oral precancer/epithelial dysplasia (8.6%) was common in females with a shammah habit. Bucco-alveolar mucosa was commonly involved and clinically presented mostly as white/red patches. Most cases were mild followed by moderate and severe dysplasia. Tumours of other histological types (3%) include 1 ameloblastic carcinoma, 3 malignant salivary gland tumours and 5 sarcomas. Conclusions: In this study, it was found that oral cancers reported in the pathology service to be a common occurrence. This study reconfirms previous reports of the high burden of oral cancer in this population This indicates that conventional preventive programs focused on oral cancer are in need of revision. In addition, further research into identifying new risk factors and molecular markers for oral cancer are needed for screening high risk individuals.

  • Oral mucosal melanoma is a very rare type of malignant melanoma, the characteristics of which differ from those of cutaneous melanoma. Primary amelanotic melanoma of the mandibular gingiva, which can invade the mandibular bone, is very rare worldwide. Here, we report a case in which we performed a reconstruction of the mandible and gingiva using the fibula osteocutaneous free flap procedure to treat a patient diagnosed with a primary amelanotic melanoma of the mandibular gingiva. The procedure was successful, and no recurrence was observed 10 months after surgery. Oral mucosal melanoma has a much poorer prognosis and a lower 5-year survival rate than cutaneous melanoma. However, recently, immunomodulatory therapies for mutations in melanocytic lesions have been used effectively to treat the increasing number of patients developing this type of melanoma, thus improving the prognosis of patients with oral mucosal melanoma.

  • The information concerning epithelial dysplasia of the oral cavity has been relatively little published. Of the histolgic grades, most of the cases were classified as moderate and severe category. Their ages ranged from 27 to 78 years(mean 57 years). The developmental incidence by sex was superior in male by ratio of 6 : 1. Epithelial lesions were located in the buccal mucosa, Floor of the mouth, the gingiva and the tongue. It is generally believed with a few exceptions that mild degree of epithelial dysplasia do not indicate any great danger for the patient. But severs dysplasia indicates that there is a very considerable risR of malignant transformation. Surgical excision is the effective method of controlling epithelial dysplasia. The authors investigated 7 cases of epithelial dysplasia histopathologically, 2 patients of them had malignant transformation. We discuss the clinical feature, treatment, prognosis, and histopatholgic analysis with literature reviews.

  • The dimensional stability of tissue conditioners characterizes the ability of the materials to yield accurate functional impressions of oral mucosa. This study evaluated the viscoelastic property and the linear dimensional changes with the factor of time and thickness of tissue conditioners ($COE-COMFORT^{TM}$, Visco-gel. $COE-SOFT^{TM}$, Soft-Liner). The thickness of these materials were changed (1.5mm, 3.0mm) and the percentage changes in dimension were measured at 1h, 12h, 24h, 36h, 3day, 7day after specimen preparation. From the results large differences appear between the various tissue conditioners. The results suggest that the period recommended for forming functional impression would be 2-3days after insertion in the mouth. in addition. it is important to select tissue conditioners suitable for functional impression because of the wide range of dimensional stability among the materials.

  • Allergic rhinitis is an allergic reaction characterized by sneezing, coughing, itchy nose, mouth and throat, congestion and/or nasal discharge. The offending allergens are usually pollens, molds, dust mites and animal allergens. We aimed to observe inhibitory effects of Bojungikgi-tang on incerase of the number of eosinophil and neutrophil, and protective effects of nasal mucosal tissue in the allergic rhinitis. 1. In Inhibitory Effect of Bojungikgi-tang on Increase of the number of Eosinophil in Serum, Bojungikgi-tang showed significant effects.(p〈0.05) 2. In Inhibitory Effect of Bojungikgi-tang on Increase of the number of Neutrophil in Serum, Bojungikgi-tang showed significant effects.(p〈0.05) 3. In histopathologic change of nasal mucosal tissue, Bojungikgi-tang showed significant protective effects. Depending upon above results, it is considered that Bojungikgi-tang has the inhibitory effects on the process of allergic rhinitis and that it could be used in reliving patients of the symptoms caused by allergic rhinitis.
