Neurofibromatosis type 1, an autosomal dominant disorder with prevalence of 1 per 3000 people, has clinical features of cafe au lait spots in skin, multiple neurofibroma and dysplasia in skeletal, endocrinal, and blood vessel systems. Actual intraoral neurofibromas are known to occur in 25% of patients. A 9 year-old girl diagnosed with type 1 neurofibromatosis visited our hospital with chief complaint of gingival swelling. Gingival enlargement in lower anterior region existed and cafe au lait spots were confirmed in patient' skin. Enlarged gingival tissue were excised under local anesthesia. Neurofibroma was confirmed with biopsy. Clinical examination after months showed fine recovery without any evidence of recurrence. Due to its possibility of recurrence, periodic follow-up will be needed.

Maxillary sinus squamous cell carcinoma is a relatively rare disease, comprising only 3% of malignant diseases of head and neck. As the growth rate is high and its prognosis is poor compared to others, the 5-year survival rate of maxillary sinus squamous cell carcinoma(MSSCC) is 23.4-49%. We introduce two rare clinical cases of squamous cell carcinoma originated from maxillary sinus of which symptoms include toothache and gingival swelling. On clinical examinations of both patients, deep periodontal pockets on upper right posterior teeth were detected. On panoramic images, the bony destruction of the maxillary sinus and its surrounding structures were not obvious and only alveolar bone loss was noted. It is difficult to diagnose MSSCC at an early stage due to symptoms of tooth pain and gingival swelling that are similar to that of periodontal diseases. However, if the symptoms do not improve after routine treatment of upper teeth, dentists should bear in mind of underlying malignant mass as differential diagnosis, thus early detection of the lethal disease. The aim of this study is to caution dental practitioners that malignancies have a potential to mimic periodontal diseases by introducing two cases of maxillary sinus squamous cell carcinoma presented as periodontitis.

A 15-year-old patient, who had been diagnosed and treated as Burkitt cell type acute lymphoblastic leukemia (ALL-L3) already, visited our department. He complained of gingival enlargement and loosening teeth 1 month ago. The clinical examination revealed anterior open bite, gingival enlargement, and nontender swelling particularly in molar regions of both jaws. Deep periodontal pockets and severe mobility was shown on most of the teeth. The panoramic radiographs showed severe bone destruction and extrusion of the molars. The contrast enhanced CT showed multiple enhanced mass and bone marrow obliteration in both jaws. Chemotherapy was done and the swelling was subsided at 1 month later. In conclusion, radiologic findings of leukemia with soft tissue mass, known as chloroma or granulocytic sarcoma, mimic those of lymphoma, so blood test may be needed for the final diagnosis.

The purpose of this study was to analyze the oral symptoms experienced by adolescents according to Body Mass Index. We analyzed the data using the Korea Youth Risk Behavior Web-based Survey and conducted complex-sample descriptive statistics on 55,728 participants. The prevalence of sensitive teeth, tooth pain, gingival bleeding, and swelling was highest in the overweight group (36.8%, 23.9%, and 19.2%) and lowest in the underweight group (34.6%, 20.8%, and 17.0%) (p<0.001). Tooth pain, gingival bleeding, and swelling were significantly higher (all 1.08) in the overweight group than in the normal group. Halitosis was 1.19-and 1.43-higher in the overweight and obese groups, respectively. The relationship between systemic diseases and oral health among adolescents should be further investigated.

Enlargement of the gingiva caused by phenitoin, an anticonvulsant used in the treatment of epilepsy, occurs in some of the patients receiving the drug. Its incidence varies from 3 to 62 percent, with the greater frequencies in younger patients. The hyperplasia is usually generalized throughout the mouth, but is more severe tendency in the maxillary and mandibular anterior regions, 18 year old male patient was admitted to our Department of Dentistry with the complaint of generalized painless gingival swelling. After the consult of the N.M. and laboratory study, the gingivectomy and gingivoplasty was performed. The periodontal pack and tin foil was applied on the attached gingiva to protect a surgical site and bleeding control. We obtained a good result of improved esthetics and function.

The oral cavity is easily accessible for direct exposure of a malignant disease. 1 percent of the oral malignant tumors are of metastatic origin and approximately 10 percent to 25 percent of the 1 percent fraction originate from the lungs. A case of metastatic lung carcinoma to the gingiva in a 88-year-old male is reported. He complained of pain and swelling between right maxillary 1st premolar and 2nd molar. Although surgical excision of the lesion has been done, the gingival lesion developed as a quickly growing mass and recurred 2 weeks after surgical excision. The gingival mass was histopathologically diagnosed as an undifferentiated carcinoma. Epithelial layer was continuous without ulceration and it seems that the cancer cells are originated from primary tumor. Infiltrated cancer cells were pleomorphic and dyskeratotic. The cells had 2 or more nuclei, not showing squamous or glandular differentiation. Immunohistochemical study revealed the cells originated from the epithelial cells. The prognosis is poor, because prognosis depends on surgical elimination of the primary tumor.

Gingivitis is the most prevalent type of periodontal disease and the dental plaque is considered as a major contributory factor. As the poor oral hygiene is firmly related to the occurrence of periodontal disease, pediatric dentist should make every effort to promote the oral health and control the plaque effectively for the high risk patients, especially for those who are under orthodontic treatment. P.M.T.C.(Professional Mechanical Tooth Cleaning), introduced by Dr. P. Axelsson in 1969, is a very effective method of plaque removal and can be performed by specially trained personnel. Two pediatric orthodontic patients were treated by P.M.T.C. for the elimination of gingivitis and gingival swelling. Signi ficant improvements of gingival condition were achieved in both cases but additional preventive programs and home care along with professional office care seem to be necessary for the best result.

The purpose of this study was to compare clinical results of guided tissue regeneration(GTR) using either a nonresorbable ePTFE membrane or a resorbable membrane made from a synthetic copolymer of glycolide and lactide(PLGA) in the treatment of human class Ⅱ furcation defects. The ePTEE membranes were applied to 16 patients with maxillary molar buccal class Ⅱ furcation defects as Group I, PLGA membranes were applied to 15 patients with maxillary molar buccal class Ⅱ furcation defects as Group Ⅱ, ePTFE membranes were applied to 20 patients with mandibular molar buccal class Ⅱ furcation defects as Group Ⅲ and PLGA membranes were applied to 20 patients with mandibular molar buccal class Ⅱ furcation defects as Group Ⅳ and bone graft materials(DFDBA) were applied in all groups. Probing depth, gingival recession, clinical attachment level, tooth mobility and sulcus bleeding index(SBI) were measured at baseline, 3, 6 and 12months postoperatively. In addition, membrane exposure levels were measured at surgery, 1, 2 and 6weeks postoperatively and postoperative complications were evaluated. The results were as follows: In all groups, there were statistically significant differences in probing depth reduction, gain of clinical attachment and mobility reduction at values of 3, 6 and 12months postoperatively compared to values of baseline, whereas no significant differences in SBI except Group I and gingival recession(p<0.05). Membrane exposure levels were increased at 1, 2 and 6weeks postopratively compared to value of baseline in Group I(p<0.05). There were no statistically significant differences between ePTFE and PLGA membrane in probing depth, clinical attachment level and SBI. There were minimal gingival recession and membrane exposure in Group Ⅳ and pain and swelling were the most common postoperative complications in Group Ⅱ, Ⅲ(p<0.05). In conclusion, this study showed that both nonresorbable membrane and resorbable membrane were effective similarly in the treatment of class Ⅱ furcation defects, without statistical differences in clinical measurements.

A 31-year-old male with the complaint of severe limitation of mouth opening was referred to our department of Chonbuk National University Hospital. The physical status of the patient was hyposthenic. Extraoral examination showed no condylar movement of the both temporomandibular joints, no pain, no facial swelling or paresthesia. Intraoral examination showed several cervical caries on the upper anterior teeth, and gingival swelling on the whole dentition. Transcranial view showed no condylar movement, and narrowing of joint spaces. Chest P-A view showed straightening of thoracic, lumbar spine, and squaring of vertebrae of the same spines. Conventional lateral radiograph of cervical spine showed calcification of the intervertebral ligament. Computed tomograph showed extensive bone formation between temporal bone and the condylar head at both sides. Laboratory findings showed positive reaction on HLA-B27 histocompatibility antigen and increased level of IgA, IgG, ESR. Based on the clinical, radiographic, and the laboratary findings, final diagnosis was made as bony ankylosis of the both temporomandibular joints secondary to ankylosing spondylitis.

This study was to survey the relationship between employment stress and self-rated oral health status in university students from Sep. 2 to 27, 2019. Data were analyzed using the SPSS 22.0 program. In case of high employment stress, the comparative risk of self-rated oral health status was 1.7 times in Gingiva swelling, 1.46 times in ulcer and 1.53 times in hypersensitivity. After correcting the general characteristics (gender, age, grade, major), the comparative risk was 1.56 times for Gingiva swelling, 1.42 times for ulcer and 1.44 times for hypersensitivity. Therefore employment stress was found to be related to oral health and it is considered necessary to find ways to prevent and manage oral health by seeking various methods such as counseling support or stress control to reduce employment stress.
