Necrotizing ulcerative gingivitis(NUG), necrotizing ulcerative periodontitis(NUP), necrotizing stomatitis (NS), and Noma (cnacrum oris) are rapidly destructive debilitating and potentially serious oral infection which considered to be different clinical stages of the same process. These have been collectively referred to as: Vincent's infection, infectious oral necrosis, or necrotizing gingivostomatitis(NG). Prevalence of necrotizing gingivostomatitis is $0.19{\sim}0.5%$ and peak incidence is 2-6 years of age. The etiology and pathogenesis of necrotizing gingivostomatitis have been associated with virulent bacteria and impaired host defense and the primary diagnostic signs are pain, interdental ulceration or necrosis, and gingival bleeding. Secondary diagnostic sign is pseudomembrane. This case report was about oral conditions and treatment of the patient who referred from the Dept. of PED and diagnosed a necorotizing gingivostomatitis.

Objectives: This study aimed to analyze the association between self-assessed periodontal symptoms and glycated hemoglobin levels in patients with type 2 diabetes. Methods: This cross-sectional study involved 156 patients with type 2 diabetes who were aged 50 years or older. Structured questionnaires were used to investigate the self-assessed periodontal symptoms of the patients. The glycated hemoglobin test was performed to evaluate their long-term blood glycemic control. Chi-square test and logistic multiple regression were performed to analyze the factors associated with glycated hemoglobin levels. Results: Compared with patients aged 65 years and above, more patients aged 64 years and below showed poor glycemic control (p=0.020). Further, compared with patients without self-perceived gingival bleeding and halitosis, more patients with these two conditions showed poor glycemic control (p<0.05). Compared with the group of patients without any periodontal symptoms, the group of patients that had at least one periodontal symptom had a higher proportion of patients with poor glycemic control (p<0.001). In the logistic regression model, gingival bleeding and halitosis were the factors most associated with hyperglycemia (p<0.05). Conclusions: The results of our study suggest that gingival bleeding and halitosis can predict hyperglycemia in patients with type 2 diabetes.

The majority of chronic gingival ulcerative lesions are known to be due to autoimmune disease such as oral lichen planus, benign mucous membrane pemphigoid or pemphigus vulgaris. Topical or systemic corticosteroids are mainly used and adjuvant drugs like immunosuppressant, anti-inflammatory drugs, antimalarials or antimetabolites can also be prescribed. Because systemic corticosteroids causes various side effects, such as gastrointestinal disturbance, osteoporosis, diabetes or adrenal suppression. So, topical steroid therapy is main treatment for chronic gingival ulcerative lesion confined to small area. However, there's also limitation of topical corticosteroids. The effect of the corticosteroids decreases due to salivary flow and the movement of the tongue, lips, or buccal mucosa. When the lesions are widely distributed or positioned deeply in oral cavity, it is hard to apply the medication on patients' own. Moreover, it can be applied to unaffected mucosa. Although occlusive steroid therapy using stent was reported to minimize taking steroid and overcome the faults of applying topical steroids, it has been used less frequently in the clinical field. Therefore, this report is going to find out the usefulness and the way to utilize clinically through the case which acted satisfactorily by performing topical steroid therapy using stent on chronic ulcerative gingival lesions.

This case report describes an uncommon treatment method for crown-root fractured incisor with immature root. A 7-year-old girl was referred for treatment of crown-root fractured maxillary central incisor. The fracture line extended to 1/2 of the total tooth length with incomplete root formation. The prognosis of crown-root fracture is usually poor and extraction is usually undertaken. But, in the mixed dentition, extraction of maxillary permanent incisor results in many complications, such as resorption of alveolar bone, poor esthetics, pronunciation and mastication. Conservative therapy in the permanent dentition comprises of few treatment modalities; supragingival restoration, gingivectomy, orthodontic extraction of apical fragment, surgical extrusion of apical fragment with or without rotational replantation. However, in this case, these indications are not applicable, so intentional replantation with adhesive resin system is the treatment of choice. The tooth was followed-up for 12 months. Currently, there are no symptoms. Since this modality adopts the respective advantages of both intentional replantation and adhesive treatment, it might be the treatment of choice in cases of vertical crown-root fracture.

교합의 부조화는 외상성교합을 야기시킬 뿐만 아니라 치태의 침착을 용이하게 하며 일단 침착된 치태의 제거에도 애로점이 있고 외과적으로 치주낭을 제거하기 위한 술식을 적용할 때에도 문제점이 있다. 따라서 교합의 부조화를 치료해주는 교합치료는 완벽한 치주처치를 위한 중요한 한 분야이다. 특히 치주과 영역에서 외상성교합의 처치는 필수적이며, 그 방법도 대단히 다양하다. 외상성 교합의 증상에 따라서 치료방법을 선택하자면 다음과 같다. 우선 치은조직에 치은퇴축 혹은 형태의 이상이 야기되었을 때에는 이에 따라 외과적인 처치가 선행되어야 함은 물론이며 다음 단계가 치아의 위치이상을 교정적인 처치를 통하여 정복하거나 동요치를 안정시켜줄 필요가 있으며 또한 정확한 교합조정술이 필요하다. 교합조정술에 대한 제반 사항과 술식에 대하여는 본지, 1982년도 6월호에 상세히 언급되었으므로 본 원고에서는 교정적인 처치방법과 치주고정장치의 적용에 대하여 기술 하고자 한다.

The purpose of this study was to observe the potentiality of a mixture of antibiotics to relieve the endodontic and periapical infections in primary teeth. A mixture of metronidazole, ciprofloxacin, and minocyclin in distilled water or in a root canal sealer were used to disinfect the infected endodontic and periapical lesions. For application of this mixture, medication cavities were prepared at orifices of root canals by using the $Fissurotomy^{(R)}$ burs(S S White, USA). The cavities and bottom of pulp chamber were filled with antibiotics mixture. In this cases, clinical symptoms were improved following a single application of that mixture. Gingival swelling, pain, and fistulae were disappeared within a week. More long term evaluation will be needed. Although there were no reports of side effects, care should be taken if children are sensitive to antibiotics. Within the limitations of this case, the mixture of 3 antibiotics provided an excellent improvement in treatment of infected primary teeth under the physiologic root resorption.

There have been many treatment methods for traumatic subgingival crown fracture and intrusion without spontaneous eruption. The orthodontic forced eruption generally results in favorable clinical findings than crown lengthening with osteotomy and intentional replantation. In first two cases with subgingival crown fracture due to trauma, authors applied orthodontic forced eruption with axed appliance after root canal therapy and then restored them with composite resin. In another case with traumatic intrusive luxation, we observed spontaneous eruption of the corresponding tooth for about 6 months and then returning it to normal position by forced eruption with removable appliance, but root canal filling was conducted after apexification due to devitalization during forced eruption, and so clinically favorable results were obtained.

Burkitt lymphoma (BL) is an aggressive form of non-Hodgkin's B-cell lymphoma found primarily in the pediatric population. In the oral cavity, this tumor can grow rapidly and often brings about facial swelling or development of an exophytic mass involving the jaws. A 5-year-old boy was referred for swelling and pain in the left mandibular area. The patient showed diffuse swelling on the left side of the mandible and firm-moderate tenderness upon palpation. An intraoral examination showed moderate mobility and sensitivity to percussion on the left primary first and second molars, without severe caries. A radiographic examination revealed complete loss of the lamina dura on the left primary second molar and permanent first molar. There was a radiolucent osteolytic lesion and destruction of the cortical bone of the left mandibular body. Based on the clinical, radiographic, and immunohistochemical findings, the patient was diagnosed with BL, and was referred to a pediatrician for systemic evaluation and intensive chemotherapy. Even before the completion of chemotherapy, the swelling resolved and the displaced teeth were relocated to a normal position. This patient showed a good prognosis due to prompt diagnosis and intensive chemotherapy. Early diagnosis and referral for treatment can prevent the development of BL.
