BACKGROUND & OBJECTIVE: The purpose of this study is to prove the effectiveness of professional maintenance care to the periodontal disease by non-surgical approach with the toothpick method to improve the periodontal health. METHODS: The patients of this study were composed of 46 patients( 18 men and 28 women), suffering from chronic adult periodontitis, who had visited the department of dental clinic center. All of the subjects were over 50years old and be treated just by non-surgical method. Professional maintenance care using the toothpick method was performed every 3 months, and evaluations were also done after 1, 2, and 3 year-professional maintenance care based on the indices such as plaque index(O' Leary index), periodontal probing pocket depth, bleeding on probing, tooth mobility, the number of tooth loss, and the rate of tooth loss representing the state of periodontal health. RESULTS: 1. The longer the maintenance care, the more the effectiveness of controlling plaque. The rate of decrease in the dental plaque index was 1.5%, 4.2%, and 6.5% in 1, 2, and 3 year maintenance groups respectively(P>0.05). 2. The periodontal pocket depth decreased depends on the severity of periodontal pocket depth in all groups the maintenance years(P<0.05). 3. On the evaluation of the bleeding tendency on probing, there was a significant difference in 1 year- maintenance group(P<0.05), but the other groups did not show any difference statistically(P>0.05). 4. Tooth mobility has decreased in the maintenance years, but did not show any difference statistically(P>0.05). 5. The number and the rate of tooth loss among the patients of 1year-maintenance group was 0.38, 1.44% respectively and that of 3 year-maintenance group was 0.44, 1.73% each. CONCLUSION: The results of this study mentioned above suggest that professional maintenance care should be operated effectively to prevent and to maintain the periodontal disease systematically on the purpose of proving the quality of life, and that it could be applied to the medical insurance system in other to try to make the most of the adult oral health care positively.

OBJECTIVES: This study investigated on the severity of dry mouth in the hansen people and the association between dry mouth(low, moderate and high) with pre and post wearing denture satisfaction. METHODS: Data were obtained from a cross-sectional survey of 104 hansen people(mean age=69.3). Data were collected by means of a personal interview from April 30 through to Jane 20, 2014. Pre and post wearing denture satisfaction was measured by the 24-items and dry mouth was measured by the 4-items. The data was analysed with t-test, One-way ANOVA, and Logistic regression using the SPSS program. RESULTS: Regarding perception of dry mouth, the subjects achieved a mean of 6.13 out of a maximum 12 points. Scores were categorised as high(8~12), medium(5~7) or low(1~4) and the proportion were 24.5%(9.56), 42.2%(5.81) and 33.3%(4.00) respectively. Those who were older and had fewer natural teeth felt that their perception of dry mouth was more severe. A logistic regression analysis showed that the subjects perception of dry mouth had a significant impact on their gender (OR=2.73), comfort (OR=0.21), aesthetic appreciation (OR=7.56) satisfaction. CONCLUSIONS: Based on the findings, the perception of dry mouth has a significant and negative impact on denture satisfaction. These results suggest that oral health promotion should be considered various factors related dry mouth in the elderly with removable denture.

Intraocular tension may be acutely changed by many drugs and by various physiologic events. AN acute rise in intracoular tension may be catastrophic if it occurs when the globenis open and leads to expulsion of contents. Most general anesthetics cause a decrease in intraocular pressure, although a few causes increased intraocular pressure. Midazolam is a 1,4-benzodiazepin derivative synthesized by Walser and Freyer in 1975. Earlier studies with midazolam have demonstrated it efficacy for induction of anesthesia and premedication. It is also desirable to know if all anesthetic agents which produce general anesthesia and which are pharmacologically different affect intraocular pressure in a similar manner. Therefore investigation of the influence of midazolam on intraocular pressure in 25 patients was undertaken at the Department of Anesthesiology, Hanyan University. All patients had no known eye abnormalities. The patients were not premedicated. In all patients the intraocular pressure was measured before induction of anesthesia, after instilling a 0.5% tetracaine into the conjunctival sac. A second reading was taken after induction of midazolam (0.2mg/kg of body weight) and a third after injection of succinylcholine(1mg/kg of body weight) and a fourth after endotracheal intubation. A Schiotz tonometer with a 5.5gm and a 7.5gm weight was used. In addition to the tonometric determination, the blood pressure, pulse rate and respiratory rate were recorded before and after induction of midazolam. An attempt was tried to keep the intraocular pressure changed as many and to minimize the other factors affecting intraocular pressure. To achieve this, supine position and constant gas flow was maintained. Special care was taken to avoid pressure on the patients eye and to maintain a fully patent airway to prevent respiratory disturbances leading to straining and increased venou pressure. Endotracheal intubation was performed with the aid of succinylcholine to avoid cough or laryngospasm. The results of the observation with the above mentioned method were tested by student t-test statistically. Each patient acted as his own control. There was a fall in intraocular pressure in 17 patients among 25 patients(average 1.8mmHg), but no significant change followed by the use of midazoam. The blood pressure variations were between 10 and 40 mmHg, during the course of anesthesia and could not be related to intraocular pressure changes. Intraocular pressure changes had no relation to pulse and respiratory rate variations. This finding indicated that benzodiazepine as a class of drugs have well described muscle relaxant properties that are primarily central(supraspinal)rather than peripheral(myoneural) in action. There was a rise in intraocular pressure in 19 patients among 25 patients, followed by the use of succinylcholine and 23 patients among 25 patients, after endotracheal intubation. According to Feldman and Crawley, diazepam potentiated the myoneural blocking effects of gallamine and antagonizes the effects of succinylcholine. Nevertheless Dretchen demonstrated that the clinical doses of diazepam did not potentiated the muscle relants. Our finding showing no apparent succinylcholine interaction with midazolam are consistent with the finding of Dretche.

The upper and the lower master models of Class II mod.1 by the Kennedy of classification were duplicated to the dentists in the dental clinic Suncheon, and the status of the surveying procedure, the form and type of the major connector, the form and type of the direct retainer, the location and status of the indirect retainer, and the modification of abutment were surveyed and analyzed and were compared to the principles of the design rationale of the removable partial denture to evaluate whether or not each component of the removable partial denture framework designed by the dentists. The analyzed results were as follows: 1. The status with or without the surveying procedure was showed 7 cases(10.29%) and 61 cases(89.71%) respectively. 2. Single palatal strap, A-P bar, broad palatal plate, complete coverage palatal major connector, single palatal bar, U-shaped palatal connector, and the others without drawing of the major connector were 27 cases (38.57%), 25 cases(35.71%), 5 cases(7.01%), 4 cases(5.71%), 2 cases (2.86%), 1 cases(1.43%), 6 cases(8.57%) respectively in the design patterns of the maxillary major connectors, and lingual bar, linguoplate, and others without drawing of the major connector were 55 cases(80.88%), 11 cases(16.18%), 2 cases(2.84%), respectively in the pattern of the mandibular major connectors. 3. The direct retainer designed to the 1st bicuspid of the upper left and the lower right adjacent to the free-end edentulous area was that the design of bar clasp was 67.41% in the highest rate and that of Akers clasp was 23.36%. 4. The direct retainer designed to the 1st bicuspid of the upper right and the lower left was that the of Akers clasp was 56.62% in the highest rate and that of bar clasp was 33.82%. 5. The mesial rests of the 1st bicuspid of the upper left and the lower right adjacent to the free-end edentulous area were 77.46%, 66.20% respectively and the distal rests and mesial rests of the 1st bicuspid of the upper left and the lower right were 58.82%, 55.71%, 38.24%, 38.57% respectively and the mesial rests of the 2nd molar of the upper right and the lower left were 95.71%, 95.65% respectively, viewed from the location of the occlusal rest seat. 6. The cases without the design of the indirect retainer were 51.47% in the upper and the lower master models respectively. 7. The modification of abutments(surveyed crown) of upper and lower teeth were 8.82%, 8.82% respectively.

Objective: The present study aimed to analyze and compare the prognostic performances of Revised Trauma Score (RTS), Injury Severity Score (ISS), shock index (SI), and modified Early Warning Score (MEWS) for in-hospital mortality in severe trauma. Methods: This retrospective observational study included elderly (≥65 years) patients admitted for severe trauma between January 2018 and December 2018. Receiver operating characteristics analysis was performed to examine the prognostic performance of the four different tools. The primary outcome was in-hospital mortality following an injury. Results: Of the 279 patients included in the study, in-hospital mortality was 20.1% (n=56). In multivariate analysis, age (odds ratio [OR], 1.055; 95% confidence interval [CI], 1.004-1.109), ISS (OR, 1.080; 95% CI, 1.008-1.157), Glasgow Coma Scale (OR, 0.842; 95% CI, 0.785-0.904), and respiratory rate (OR, 1.261; 95% CI, 1.071-1.486) were independently associated with in-hospital mortality. The area under the curves (AUCs) of MEWS, RTS, ISS, and SI were 0.851 (95% CI, 0.763-0.857), 0.733 (0.677-0.784), 0.664 (0.606-0.720), and 0.567 (0.506-0.626), respectively. The AUC of MEWS was significantly different from those of RTS (P=0.034), ISS (P=0.001), and SI (P<0.001). Conclusion MEWS has the highest prognostic performance for in-hospital mortality among four different tools in elderly patients with severe trauma.

Objective: Previous studies have suggested that epinephrine reduces brain tissue O2 tension (PbtO2) after the return of spontaneous circulation (ROSC) via α1-adrenoceptor stimulation and that pralidoxime had α1-adrenoceptor inhibitory action together with non-adrenergic vasopressor action. We sought to investigate the effects of pralidoxime administered during cardiopulmonary resuscitation (CPR) as a sole vasopressor on PbtO2 after ROSC. We hypothesized that pralidoxime administration would lead to a comparable ROSC rate and a higher PbtO2 after ROSC when compared to epinephrine administration. Methods: After 7 minutes of ventricular fibrillation, 24 pigs randomly received either pralidoxime or epinephrine during CPR. Cerebral measurements, including PbtO2, were measured from the parietal cortices during the 60-minute postROSC period. Results: Coronary perfusion pressure (CPP) during CPR was significantly higher in the epinephrine group than in the pralidoxime group (P=0.012). All the animals in the epinephrine group achieved ROSC, while seven (58.3%) did so in the pralidoxime group (P=0.037). The area under the curves for PbtO2 during the post-ROSC period did not differ between the two groups. Conclusion Pralidoxime alone was significantly inferior to epinephrine in increasing CPP and achieving ROSC. In addition, pralidoxime administration did not improve PbtO2 during the post-resuscitation period as compared with epinephrine.
