This study was to evaluate the clinical evidence for the success and the predictability of the osseointegrated dental implants in the partially edentulous Korean patients. 201 patients have received total of 502 Branemark implants, which were restored with either single or multiunit fixed superstructures at the Implants Clinic, Yonsei University Dental Hospital. The clinical and radiographic evaluations carried out on the patients for maximum 8 years were assessed annually for peri-implant inflammation, implant mobility (PTV), Plaque Index (PI), Gingival Index (GI), Bleeding on Probing (BOP), Keratinized Mucosa width and any changes in the surrounding bone level. The radiographs were taken at completion of the restoration, and annually thereafter. On the last recall appointments the patients filled a questionnaire consist of 29 questions in four categories. The cumulative non-failure rate of success was 93.9%. The first year mean bone loss was 0.3mm and less than 0.2mm annually thereafter. The periodontal parameters, keratinized tissue width and periotest values stabilized after initial changes in the first years. The questionnaire has shown general satisfactory responses in all four aspect of dental implants treatment, including chewing efficacy, comfort, aesthetics and speech. The results support the predictability and success of the long-term rehabilitation of implant supported prostheses in partially edentulous Korean Patients.

Construction of an obturator for rehabilitation of a patient who underwent a maxillectomy is vital. Routinely a constructed obturator includes denture portion. A patient who may present anatomical limitations due to surgical or radiotherapy complications often challenges the clinician. Purpose: This clinical report describes a patient with severe trismus after surgical resection and radiotherapy treatment of a tumor in the upper left maxilla. Conclusion: This report describes the concepts of using a rotational path insertion for an obturator and a separately constructed maxillary denture. The stability and retention of the obturator were obtained from anatomical features. Where as these were achieved through magnetic attachments and the remaining edentulous ridge to ensure esthetic and function of the prosthesis.

For a missing teeth, orthodontic treatment may be a better choice of treatment in comparison to a conventional prosthetic replacement such as FPD, resin bonded prosthesis in view of aesthetics, periodontal health and function. Occasionally after an orthodontic treatment, an insufficient space may occur. The mini-implant could be an alternative in situations of narrow ridge dimension, where conventional root form implant could be compromised. The aim of this clinical report is to describe how a space that could not be restored with a traditional root form endosteal implant was managed and to present a technique to achieve optimal anterior esthetics in single implant restoration.

High-mobility group box 1 (HMGB1) protein has been demonstrated to play an important role in chronic inflammatory diseases including rheumatoid arthritis, and systemic lupus erythematosus. This study investigated the association between extracellular HMGB1 expression and disease activity, and clinical features of Behcet's disease (BD). Extracellular HMGB1 expression in the sera of 42 BD patients was measured and was compared to that of 22 age- and sex-matched healthy controls. HMGB1 expression was significantly increased in BD patients compared to healthy controls (78.70 +/- 20.22 vs 10.79 +/- 1.90 ng/mL, P = 0.002). In addition, HMGB1 expression was significantly elevated in BD patients with intestinal involvement compared to those without (179.61 +/- 67.95 vs 61.89 +/- 19.81 ng/mL, P = 0.04). No significant association was observed between HMGB1 concentration and other clinical manifestations, or disease activity. It is suggested that extracellular HMGB1 may play an important role in the pathogenesis of BD.

Toxocara (T.) canis and Trichuris (T.) vulpis are very important canine parasitic nematodes. T. canis parasitize in small intestine and T. vulpis parasitize in large intestine. In order to control of these nematodes, ivermectin and pyrantel pamoate compound was applied to the dogs infected with these parasites naturally and artificially. This drug was composed of 68.0 microg of ivermectin and 57.0 mg of pyrantel pamoate for small animal, 136.0 microg of ivermectin and 114.0 mg of pyrantel pamoate for middle animal, and 272.0 microg of ivermectin and 227.0 mg of pyrantel pamoate for large animal. Ivermectin in this drug is activity to nematodes and ectoparisites. Pyrantel pamoate in this drug is also activity to nematodes. In this experiment, this drug had a good efficacy against T. canis and T. vulpis in the infected dogs.

STATEMENT OF PROBLEM: Loss of the marginal bone to the first thread have been accepted but continuous effort have been made to reduce this bone loss by varying implant design and surface texture. PURPOSE: This animal study has examined the histomorphometric variations between implants with micro-thread, micro-grooved and turned surfaced neck designs. MATERIAL AND METHODS: Four mongrel dogs have been used the premolars removed and left to heal for three months. One of each implant systems with turned neck, micro-thread and micro-grooved were placed according to the manufacturers' protocol and left submerged for 8 and 12 weeks. These were then harvested for histological examination. RESULTS: The histologically all samples were successfully ossointegrated and active bone remodelling adjacent to implants. With the micro-grooved implants 0.40 mm and 0.26 mm of the marginal bone level changes were observed at 8 and 12 weeks respectively. The micro-threaded implants had changes of 0.79 mm and 0.56 mm at 8 and 12 weeks respectably. The turned neck designed implants had marginal bone level changes of 1.61 mm and 1.63 mm in 8 and 12 weeks specimens. A complex soft tissue arrangement could be observed against micro-threaded and micro-grooved implant surfaces. CONCLUSION: Within the limitations of this study, it could be concluded that implants with micro-grooved had the least and the turned neck designed implants had the most changes in the marginal bone level. The textured implant surfaces affect soft tissue responses.

Hypocalcemia is due to Hypoparathyroidism, Vitamin D deficiency, Hypomagnesemia, Inadequate calcium intake. The benefits of breast-feeding are well established. There are no need to supply calcium or Vitamin D in breast-fed infant. We report a case of infantile hypocalcemia caused by Vitamin D deficiency in exclusively breast-fed infant. He had no hypocalcemic symptom and hypocalcemia was found incidentally by routine laboratory tests during pneumonia treatment. He was presented with a low serum calcium level and 1,25(OH)2 Vit D3 level and high PTH. He was improved by Calcium and Vitamin D supplement. After then his mother continued breast feeding exclusively and resisted to feed her baby weaning food. During follow up period, hypocalcemia was recheked after discontinuation of vitamin D supplement. At 11 months of age, the calcium level was normal without vitamin D supplement after he had eaten weaning food. This report describes a case of hypocalcemia induced by vitamin D deficiency in exclusively breast-fed infant, with review of the literature.

OBJECTIVES: In the present study, we aimed to develop an oral examination smart chart application for tablet personal computers (PC). We evaluated the time required to perform an oral examination and assessed the degree of user's convenience by using this application. We determined to make our application cost and human resource effective by automatically computerizing the statistics to facilitate its application in oral health services such as national oral health research. The development of this application for tablet PCs was aimed at recording the results of oral examinations. METHODS: We produced flow charts and designed the program screen, which would replace the existing paper chart. To evaluate the efficiency of the application, 1 preventive dentistry professor and 6 dentistry students performed an oral examination on 41 subjects. We performed the oral examination in duplicate using a tablet PC and a paper chart. The data collected were analyzed using the SPSS 18.0 program. P-values less than 0.05 were considered statistically significant. RESULTS: The time required for oral examination by the study group (the group using the application) and the control group (the group using paper) were 131.93+/-10.14 and 151.85+/-7.77, respectively; the difference between these values was statistically significant (P-value=0.002). The oral examination could be performed faster in the study group (the group using the application) than in the control group; therefore, we noted that the time taken for oral examination was reduced by using the application. CONCLUSIONS: The tablet-based system has been shown to save time by omitting the step of entering the paper chart data into a computer. Further, the findings of this study can be used to establish an oral health index database with the help of additional resources. Moreover, it would facilitate creating awareness among the patients with regard to their oral health indices through the use of visual aids.
