Severely worn dentition causes various complications such as loss of tooth structure, discoloration, pulp complications and loss of function and aesthetics. In this case, the patient showed particularly severe attrition in the anterior teeth and lack of space for restoration. The amount of vertical dimension was determined based on the diagnostic wax up, and the patient’s adaptation was evaluated by using a removable occlusal splint for 6 weeks. Thereafter, the coordination of the muscular nervous system, aesthetics, temporomandibular joint were re-evaluated for 3 months by restoring the fixed provisional restoration. Through the above treatment process, the final restoration was completed with full mouth fixed prosthesis using monolithic zirconia, and functionally and aesthetically stable results were obtained.

Bilateral diaphragmatic paralysis(BDP) is a rare disorder, which can be secondary to spinal cord injury, motor neuron disease, myopathy, noninfectious polyneuropathy, infection, iced saline cardioplegia performed during cardiac surgery, or idiopathic causes. there may be typical presentations such as dyspnea, paradoxical respiratory movement, and hypercapnic respiratory failure. It needs to exclude above secondary causes to consider idiopathic bilateral diaphragmatic paralysis. We report a 51-years-old man who presented with idiopathic bilateral diaphragmatic paralysis combined with acute pancreatitis. We couldnt, find out the association of these two clinical conditions. The patient was improved by mechanical ventilation.

The reliability of emergency ultrasonographic(US) detection of hemoperitoneum and solid organ injury in blunt abdominal trauma was evaluated retrospectively. From October 1,1995 to August 31,1996,90 patients were included in the study. Ultra- sonographic findings showed a sensitivity, specificity, and accuracy of 97.6%, 97.9%, and 98.1%, respectively, in detecting intraabdominal fluid collection. We believe that US in an emergency center is a quick, safe screening method in the evaluation of blunt abdominal trauma. In our department, US has replaced diagnostic peritonaeal lavage(DPL) and computed tomography(CT) as the screening study of first choice.

PURPOSE: The purpose of this study is to investigate the changes of osteoclast differentiation inhibition according to the period of precipitation when titanium disks were immersed in Modified simulated body fluid (mSBF). MATERIALS AND METHODS: Titanium alloy (Ti grade III) disks with machined surfaces and anodized surfaces were immersed in distilled water and mSBF, respectively. The immersion periods were 7 days, 14 days, 21 days and 28 days, and the control group was immersed in distilled water for each period. RAW 264.7 cells capable of differentiating into osteoclasts were used to measure the number of adherent cells, the measurement of TRAP activity, and the expression pattern of NFATc1 by western blotting. RESULTS: The degree of inhibition of osteoclast differentiation was found to be statistically significant when the disks were immersed in mSBF for more than 14 days on both machined surfaces and anodized surfaces. There was no correlation between immersion time and cell attachment. When the disks were immersed for more than 14 days, TRAP activity was decreased and NFATc1 expression was inhibited. Futhermore, the decrease in TRAP activity and the inhibition of NFATc1 expression remained unchanged. CONCLUSION: Immersion of titanium disks in mSBF for more than 14 days can prevent RAW 264.7 cells from differentiating into osteoclasts. Inhibition activity does not change even if the immersion period is for more than 14 days.

PURPOSE: . The purpose of this study was to analyze the marginal fit of three-unit resin prostheses printed with the stereolithography (SLA) method in two build orientations (45°, 60°) and two layer thicknesses (50 µm, 100 µm). MATERIALS AND METHODS: . A master model for a three-unit resin prosthesis was designed with two implant abutments. Forty specimens were printed using an SLA 3D printer. The specimens were printed with two build orientations (45°, 60°), and each orientation was printed with two layer thicknesses (50 µm, 100 µm). The marginal fit was measured as the marginal gap (MG) and absolute marginal discrepancy (AMD), and MG and AMD measurements were performed at 8 points per abutment, for 16 points per specimen. All statistical analyses were performed using SPSS software. Two-way analysis of variance (ANOVA) was separately performed on the MG and AMD values of the build orientations and layer thicknesses. Moreover, one-way ANOVA was performed for each point within each group. RESULTS: . The margins of the area adjacent to the pontic showed significantly high values, and the values were smaller when the build orientation was 45° than when it was 60°. However, the margin did not differ significantly according to the layer thicknesses. CONCLUSION . The marginal fit of the threeunit resin prosthesis fabricated by the SLA 3D method was affected by the pontic. Moreover, the marginal fit was affected by the build orientation. The 45° build orientation is recommended.

Crohn's disease (CD) is a chronic immune-mediated inflammatory disorder. Treatment strategies for CD are targeted toward various components of the proinflammatory mediators and subsequent immune response. Recently, the anti-tumor necrosis factor (TNF) monoclonal antibody, infliximab has been used in patients with CD. However, uncommon and unusual infections have been reported during anti-TNF-alpha therapy and immunomodulator. Here, we report a case of pityriasis versicolor occurring in a patient with CD receiving infliximab treatment. The patient was successfully treated with topical ketoconazole.

Human mouth environment is known to include a variety bacteria, including Streptococcus spp., Staphylococcus spp., Actinomyces spp., Lactobacillus spp., Candida spp., Enterobacteriaceae, et al. Human oral microorganisms can cause dental caries, gingivitis, periodontitis, respiratory tract infection, and cardiovascular disease. Thus, right denture cleaning is essential to oral and general human health. The aim of this study was to evaluate the bactericidal effect of a sodium dichloroisocyanurate-based effervescent tablet (Aos Denti Germ, Aos Company, Chungbuk, Korea) against oral microorganisms. A total of 5 species Streptococcus spp. (Streptococcus anginosus, Streptococcus mitis, Streptococcus mutans, Streptococcus oralis, and Streptococcus sobrinus), Actinomyces oris, Candida albicans, and Escherichia coli were used in this study. All strains were exposed to the distilled water prepared with effervescent tablet. After the exposure, the mixture of strains and effervescent tablet was inoculated onto blood agar or MacConkey agar plate and cultured at 36℃. All strains were killed immediately on exposure to effervescent tablet. The results suggested that effervescent tablet could be used as an effective denture cleanser for dental hygiene.

Jimson weed, also known as Datura stramonium, is a member of the Solanaceae family. Jimson weed was used by American Indians for medicinal and religious purposes. All parts of the Jimson weed plant are poisons, containing the alkaloids atropine, hyoscyamine and scopolamine. So, it is caused by these components to make a anticholinergic toxicity within 6h after ingestion. Initial manifestations include dry mucus membrane, blurred, vision, thirst, difficulty swallowing and speaking, and photophobia, and may be followed by hyperthermia, confusion, agitation, combative behavior, hallucination, urinary retention, seizure and coma. We experienced two patients who developed combative behavior and agitation with pupil dilation caused by Jimson weed. They discharged with improvement after supportive for 2days.
