오늘날 단일치 임플란트의 식립은 현재 시행되고 있는 가장 일반적인 임플란트 술식 중 하나이며, 상악 전치부는 이중 가장 흔하게 시행되는 식립 부위 중하나이다. 그럼에도 불구하고 상악 전치부 단일 상실치에 대한 치료 계획은 구강 내 다른 어떤 부위보다 복잡하며 고도로 심미성을 요구하는 부위로서 아무리 경험이 많고 기술이 뛰어난 치과의사라 할지라도 시술할 때마다 큰 도전으로 여겨지는 경우가 대부분일 것이다. 상악 전치부에서 임플란트 보철의 심미적 성공을 이루기 위해서는 모든 구성 요소 하나하나에서 심미적 결과를 이룩하여야 하고 이 결과들이 완벽하게 조화를 이루게 하여야 하며 이는 결코 쉬운 일이 아닐 것이다. 시술 시 교과서의 그림처럼, 모형에 식립해 본 것처럼 쉽게 되지 않는 것은 물론 구강 내 환경이 모형과 다를 리 만무한 것이 당연한 첫 번째 이유이며 뿐만 아니라 환자 대부분의 경우 모형처럼 완벽한 경 연조직이 갖추어진 상태에서 치아만 상실된 경우는 거의 찾아볼 수 없기 때문인 이유도 크다. 즉, 원하는 위치에 식립을 하고 장기간의 심미적 유지를 위해서는 경 연조직에 대한 처치가 필수적인 경우가 대부분이라는 이야기이다. 이를 간과하고 식립한 경우 추후 심각한 bone의 resorption, 그에 따르는 gingiva의 끔찍한 recession, 용납할 수 없는 비심미적 보철물의 제작은 불을 보듯 뻔한 결과가 될 것이다. 따라서 상악 전치부 식립 치료계획 시 치과의사는 성공적 결과에 영향을 미칠 수 있는 모든 요소에 촉각을 곤두세우고 이들의 완벽한 처치에 최선을 다 해야할 것이다.

Bony anomaly caused by lip tie is not many reported yet. There was a case of upper lip tie wrapping into the anterior premaxilla. We represent a case of severe upper lip tie of limited lip motion, upper lips curling inside, and alveolar hypoplasia. Male patient was born on June 3, 2016. He had a deep philtral sulcus, low vermilion border and deep cupid's bow of upper lip due to tension of short, stout and very tight frenulum. His upper lip motion was severely restricted in particular lip eversion. There was anterior alveolar hypoplasia with deep sulcus in anterior maxilla. Resection of frenulum cord with Z-plasty was performed at anterior premaxilla and upper lip sulcus. Frenulum was tightly attached to gingiva through gum and into hard palate. Width of frenulum cord was about 1 cm, and length was about 3 cm. He gained upper lip contour including cupid's bow and normal vermilion border after the surgery. This case is severe upper lip tie showing the premaxillary hypoplasia, abnormal lip motion and contour for child. Although there is mild limitation of feeding with upper lip tie child, early detection and treatment are needed to correct bony growth.

Purpose: The purpose of this study was to examine the effects of using gauze frozen with normal saline or ice on thirstrelief and oral condition of laparoscopic cholecystectomy patients. Methods: A quasi-experimental nonequivalent control group, pretest-posttest design was used. Participants (n=53) received either gauze frozen with normal saline (n=17), ice (n=18) or wet gauze (n=18) for thirst-relief. The subjective thirst level and oral condition of the participants were assessed before the intervention, 15 min after the first intervention and 15 min after the second intervention. Results: After oral care was provided twice, there were significant differences in thirst level among the groups. When oral care was provided twice, the oral condition of tongue, saliva, mucosal membrane, and gingiva was improved in patients receiving gauze frozen with normal saline or ice. Conclusion: Gauze frozen with normal saline and ice can be effective for oral care in reducing the thirst level and improving the condition of the oral cavity.

One of functions of Galla Rhois (GR) is reportedly an anti-inflammatory effect on the several inflammatory diseases. However, an effect of GR related to periodontitis has not been investigated. In the present study, we examined the effect of the hexane extract of Galla Rhois (GR-H) on periodontitis. Cytotoxicity was assessed by MTS analysis using human gingival fibroblast (hGF) cells. Experimental periodontitis was induced by injecting E.coli LPS into the palatal gingiva maxillary molar thrice weekly for 3 weeks (LPS group). GR-H diluted in 1xPBS was orally administrated using a syringe at 30 mg/kg body weight and 100 mg/kg body weight once a day (GR-H group). GR-H effect on the alveolar bone loss (ABL) was digitized with a micro-CT. GR-H treatment at concentrations exceeding 0.5 mg/ml showed cytotoxic effect in hGF cells. The micro-CT among groups were presented for the different distances from cemento-enamel junction (CEJ) to alveolar bone crest (ABC). The results indicated an inhibitory effect on alveolar bone loss for orally administered GR-H in a model of LPS-induced periodontitis.

Recently, the population of patients who refuse transfusion has increased for both religious and non-religious reasons, even in life threatening emergency situations. Their refusal has highlighted the need to develop nonblood transfusion surgery techniques to decrease the risk from blood transfusions. A 57-year woman with an ulcerative lesion on the gingiva of the right upper molar area visited the department of oral and maxillofacial surgery in Dankook University Dental Hospital. After a preliminary evaluation, the patient was diagnosed with squamous cell carcinoma. As she refused blood transfusion during surgery for religious reasons, surgery was planned using recombinant human erythropoietin (rHuEPO) without a blood transfusion. The patient underwent a partial maxillectomy, supraomohyoid neck dissection, free radial forearm flap and split thickness skin graft under general anesthesia. rHuEPO and iron were used before and after surgery. The hemoglobin/hematocrit (Hb/Hct) level, iron (Fe) and total iron-binding capacity (TIBC) were assessed. The patient recovered completely without any blood transfusions. rHuEPO is a viable alternative for patients with religious objections to receiving blood transfusions.

Calcium-channel blockers such as nifedipine could be associated with gingival overgrowth. The aim of this study was to examine the role of Paeonia lactiflora Pallas(PLP) on nifedipine-induced gingival hyperplasia along with submandibular secretory function in rats. Animals in divided groups received nifedipine (250 mg/kg) alone and in PLP(100, 200 mg/kg) in orally administration for 3 weeks. Pure submandibular saliva was collected intraorally by micropolyethylene cannula and the mandibular gingiva was examined by means of dissecting microscope for signs of redness, tickness, inflammation and exuda. Twenty-one days nifedipine treatment induced gingival hyperplasia accompanied with reduced salivary flow rate and concentrations total protein, epidermal growth factor(EGF) and calcium in comparison with normals. Co-treatment of animals with nifedifine and PLP protected from gingival hyperplasia and retained flow rate, and concentrations of total protein, EGF and calcium in normal levels.

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.

Purpose: Excessive gingival display and short clinical crowns due to altered passive eruptions are major concerns for a considerable number of patients visiting dental clinics. Altered passive eruptions could be corrected through various types of periodontal surgery conformable to a classification. 3 cases are reported here on the esthetic correction of altered passive eruption to evaluate results of crown lengthening procedure. Methods: Three patients whose major complaints were excessive gingival display and short teeth were picked out for this case study. Before treatment, clinical and radiological exam was performed to choose type of surgery. Thickness and width of keratinized gingiva was measured in all three patients then they were treated by surgical methods including flap operation and depigmentation under subsequent diagnosis. Results: Uneventful healing and stable gingival margin were observed in all three patients except recurrence of gingival pigmentation of one patient. Conclusions: The treatment of altered passive eruption requires precise diagnostic procedure and could achieve better esthetic outcomes when it is accompanied by other orthodontic and orthognathic treatment.
