Purpose: implant therapy restores masticatory function by restoring lost tooth morphology. It has been shown that mastication contributes not only to food intake and digestion, but also to the improvement of overall health. However, there have been no studies on the effects of implant treatment on electroencephalography (EEG). In this study, we investigated the effects of restoration of masticatory function by implant treatment on EEG and stress. Methods: 13 subjects (6 males, 7 females, age 64.1 ± 5.8 years) who had lost masticatory function due to tooth loss and 11 healthy subjects (6 males, 5 females, age 47.6 ± 2.4 years) as a control group. EEG (θ, α, β waves, α/β ratio) and salivary cortisol were measured before immediate dental implant treatment and every month of treatment for 6 months. EEG (θ, α, β waves, α/β ratio) was measured with a simple electroencephalograph miniature DAQ terminal (Intercross-410, Intercross Co., Ltd., Japan) in a resting closed-eye condition, and salivary cortisol was measured using an ELISA kit. Results: Compared to the control group, the appearance of θ and α waves were significantly decreased and β waves were increased, and α/β ratio was significantly decreased. The cortisol level of the subject group was significantly higher compared with the control group. With the course of implant treatment, the appearance of θ and α waves of the subject group increased, while β waves decreased. However, no significant difference was observed. The α/β ratio of the subject group increased from the first month after implant treatment and increased significantly after 5 and 6 months (0 vs. 5 months: p implant treatment and significantly decreased after 3 or 4 months (0 vs. 3 months: p < 0.05, 0 vs. 4 months: p < 0.01). These results suggest that tooth loss causes mental stress, which decreases brain stimulation and affects function. Re

Are there any ways to analyze objectively if any good changes happen to the bodies for the patients with acquired edentulous by getting a treatment to recover occlusion? In this study, we focused on interleukin 6 (IL-6) as inflammatory cytokine, cortisol known as a stress related substance and secretory immune globulin A (SIgA) related to immune reaction, and chose 14 patients who had occlusion reconstructed by the immediately loaded dental implants because occlusion contact with maxillary and mandibular dentition was lost caused by edentulous jaws or maxillary and mandibular teeth crossing each other and their jaw position and central occlusion position could not settle, and verified the relationship with changes of patients’ physical and mental states during the 6 months of the treatment and the effect of the immediately loaded implants treatment by using saliva which was non-invasive and easy to sample in biomarkers in saliva. Moreover for female subjects, the changes of facial color tones were measured by using Robo Skin Analyz-er?, a digital image analyzer, to measure the condition of their skin. In conclusion, the positive correlation between the amount of IL-6 and cortisol was not admitted. However, it was admitted that IL-6 tended to increase when a systemic change which interrupted curing such as the interruption of fusion of the implant and the bone was observed even though the patient did not notice any particular symptoms and cortisol tended to increase when the patient noticed discomfort and mentioned any events under stress on his or her medical record. Moreover with the skin color analysis by Robo Skin Analyzer?, the possibility that the occlusion treatment by the immediate implant had an effect on physical and psychological health promotion through the acquisition of the masticatory function and the aesthetic recovery was indicated.

Purpose: This study was performed to assess the utility and safety of an In-Office INR Monitoring Device and present a safe and efficient protocol for the management of patients on oral anticoagulants and/or antithrombolytics requiring routine office oral and maxillofacial surgery. Patients and Methods: Sixty-one patients requiring “minor” oral and maxillofacial surgery being treated chronically with oral anticoagulation (warfarin) were entered into the study and compared in 2 groups. The control group (n = 29) was managed by discontinuing warfarin and any anti-platelet medication(s) prior to surgery. In the study group (n = 30), the decision to continue or withhold warfarin was determined by a protocol in which patients are 1) stratified based on risk for thromboembolism, and 2) classified as requiring “major” or “minor” surgery. Procedures categorized as “minor” surgery included dental extraction(s), dental implants, soft tissue and bone biopsies, and preprosthetic bone surgery, and incision and drainage. Warfarin and antiplatelet medication were not withheld in these patients, and a Point-of-Care In-Office INR Monitoring Device was used to obtain INR levels on the day of consultation and surgery. Local measures including removal of granulation tissue, packing, suturing, etc. were utilized for hemostasis. Results: The 30 patients in the study group maintained on warfarin readily achieved hemostasis using intraoperative local measures. The mean INR measured by the In-Office INR Monitoring Device was 2.36 with a range from 1.3 to 3.2. Study group patients underwent a total of 131 separate procedures including 108 dental extractions (impactions), placement of dental implants, preprosthetic bony surgery, bone cyst removal, soft tissue biopsies, facial skin cancer repair, and incision and drainage. One patient (3%) required “minor” intervention with removal of a “liver clot” on postop day 2 with repacking and suturing. The 29 patients in the control group discontinued

Amelogenin（AMG） is a cell adhesion molecule that has an important role in the mineralization of enamel and regulates events during dental development and root formation. The purpose of the present study was to investigate the effects of recombinant human AMG（rhAMG） on mineralized tissue-associated genes in cementoblasts. Immortalized mouse cementoblasts（OCCM-30）were treated with different concentrations（0.1, 1, 10, 100, 1 000, 10 000, 100 000 ng · mL^-1） of recombinant human AMG（rhAMG）and analyzed for proliferation, mineralization and mRNA expression of bone sialoprotein（BSP）, osteocalcin（OCN）, collagen type I（COL I）, osteopontin（OPN）, runt-related transcription factor 2（Runx2）, cementum attachment protein（CAP）, and alkaline phosphatase（ALP） genes using quantitative RT-PCR. The dose response of rhAMG was evaluated using a real-time cell *** RNA was isolated on day 3, and cell mineralization was assessed using von Kossa staining on day 8. COL I, OPN and lysosomalassociated membrane protein-1（LAMP-1）, which is a cell surface binding site for amelogenin, were evaluated using immunocytochemistry. F-actin bundles were imaged using confocal microscopy. rhAMG at a concentration of 100 000 ng · mL^-1 increased cell proliferation after 72 h compared to the other concentrations and the untreated control group. rhAMG（100 000 ng · mL^-1） upregulated BSP and OCN mRNA expression levels eightfold and fivefold, respectively. rhAMG at a concentration of 100 000 ng · mL^-1 remarkably enhanced LAMP-1 staining in cementoblasts. Increased numbers of mineralized nodules were observed at concentrations of 10 000 and 100 000 ng · mL^-1 rhAMG. The present data suggest that rhAMG is a potent regulator of gene expression in cementoblasts and support the potential application of rhAMG in therapies aimed at fast regeneration of damaged periodontal tissue.
