  • The purpose of this study was to evaluate relationship of probing attachment levels, radiographic measurements and surgical measurements according to gingival inflammatory condition. Patients with incipient to moderate periodontitis were selected. Upper and lower premolar and molar teeth excluding third molars were measured. At first visit, gingival index and bleeding on probing were taken, and subjects were grouped into 4 categories as follows : Experimental group I : gingival index 1 and no bleeding on probing. Experimental group II : gingival index 2 and no bleeding on probing absent. Experimental group III : gingival index 1 and bleeding on probing present. Experimental group IV : gingival index 2 and bleeding on probing present. Probing attachment levels were measured with manual probe on mesial and distal surfaces from cementoenamel junctions to terminal ends of probe. Radiographic measurements were made to assess bone loss by measuring the distance from cementoenamel junction to the alveolar crest. After thorough scating, a flap was raised exposing the alveolar bone and surgical measurements were made from cementoenamel junction to alveolar bone. The results were as follows: 1. Differences between probing attachment level and radiographic measurements showed $1.01{\pm}0.73mm$ for experimental group I, $0.98{\pm}0.48mm$ for experimental group II, $0.59{\pm}0.66mm$ for experimental group III, $0.98{\pm}0.38mm$ for experimental group IV and with no significant difference between groups. 2. Differences between probing attachment level and surgical measurements showed $1.36{\pm}0.80mm$ for experimental group I, $1.47{\pm}0.54mm$ for experimental group II, $1.06{\pm}0.39mm$ for experimental group III, $1.41{\pm}0.40mm$ for experimental group IV and with no significant difference between groups. 3. Differences between surgical and radiographic measurements showed $0.36{\pm}0.48mm$ for experimental group I, $0.51{\pm}0.54mm$ for experimental group II, $0.57{\pm}0.72mm$ for experimental group III, $0.41{\pm}0.49mm$ for experimental group IV and with significant difference between experimental group I and experimental group II, III, IV(P<0.05).

  • Since bacterial plaque is known as the major cause of every oral disease, it is necessary to control plaque to maintain periodontal health. Although tooth brushing has been the typical method of plaque control, additional use of plaque control devices are necessary for cleansing interdental areas. Dental floss has been used for a long time as the additional plaque control device and proved to be effective. The newly developed embossed new dental pick is composed of elastic plastic material in form with its tip longer than other toothpick. In addition, as thickness of the tip gradually increases, it can be adapted easily with minimal trauma to interdental gingiva. The embossed tip can remove dental plaque easily, and the opposite end can approach lingual and palatal areas through triple angulation. Therefore, the authors studied the effect of embossed new dental pick and dental floss on periodontally involved 15 patient. The following results were obtained. 1. For embossed new dental pick, probing depth at baseline, 1 week, 4 weeks were $3.6{\pm}0.6mm$, $3.4{\pm}0.5mm$, $3.2{\pm}0.5mm$, respectively, and $4.2{\pm}0.9mm$, $4.1{\pm}0.9mm$, $4.0{\pm}0.9mm$, respectivly for clinical attachment level. 2. In case of embossed new dental pick, bleeding on probing at baseline, 1 week, 4 weeks were $43.0{\pm}4.4%$, $28.5{\pm}5.1%$, $22.2{\pm}5.6%$, respectively, and, at 1 week and 4 weeks, they were significantly different from that of dental floss. 3. Gingival index of toαhpick at baseline, 1 week, 4 weeks were $1.7{\pm}0.5$, $1.0{\pm}0.3$, $0.9{\pm}0.2$, respectively, and, $1.7{\pm}0.5$, $1.1{\pm}0.4$, $1.0{\pm}0.4$, respectively for plaque index, and $3.0{\pm}0.5$, $1.7{\pm}0.5$, $1.4{\pm}0.4$, respectively for proximal plaque index. proximal plaque index at 4 weeks was significantly different from that of dental floss. 4. The result of questionnaire showed that the two types of device were both satisfactory, however, embossed new dental pick had higher preference as well as satisfaction. As a result, embossed new dental pick is thought to be clinically effective for its simplicity and good accessibility.

Methods: Participants were 1,831 total students from 14 middle school who lived Seosan with mean age of 12.46 years. Data was collected using a self administrated questionnaire from April 13 to May 24, 2009. Psychosocial factors and dietary habits were measured using the 5-items and 10-items. A trained investigator made an oral examination of them in natural light using a mirror and explorer to determine their DMFT index. Data were analyzed with t-test, one-way ANOVA, and Tukey test, pearson correlation coefficient using the SPSS WIN 15.0 program. Results: Regarding dietary self-efficacy, perceived benefit and perceived barrier degree, the subjects achieved a mean of $3.89{\pm}0.69$, $3.48{\pm}0.63$ and $3.82{\pm}0.63$ out of a maximum 5 points. And the dietary habit degree of subjects achieved a mean of $10.69{\pm}4.02$ out of a maximum 20 points and the DMFT index were $1.91{\pm}2.26$. Dietary habits was positively correlated with psychosocial factors and negatively correlated with DMFT index. And then perceived barrier score were negatively correlated with DMFT index. Conclusion: Based on the findings, dental caries experience is associated with perceived barrier and dietary habits. These results suggest that the implementation of health promotion should be considered for various psychosocial factors and dietary habits in adolescents.

  • Cardiac systolic time intervals (STLs) and Heather index (HI) were used to access changes in left ventricular function of six male subjects exposed to postural changes,$0^{\circ}C$, ${\pm}2^{\circ}C$, ${\pm}45^{\circ}C$, ${\pm}90^{\circ}C$, Significant prolongation of the pre-ejection period (PEP) and PEP/ LVET ratio, shortening of the left ventricular ejection time (LVET), STI, HI and $1/PEP^{2}$were observed during exposure to both $+45^{\circ}C $ and $+90^{\circ}C $But the values measured during $-45^{\circ}C $ and$-90^{\circ}C $ were reversed. Changes in fluid shift, filling volume, preload, after load and sympathetic activities may account for the observed findings. Early response of cardiac foctions was recorded using impedance cardiography. This method is very simple but accurate. Thus it will be useful in this aerospace and work physiology. In conclusion, STIs appear to provide reliable noninvasive method for examining changes of cardiac function during exposure to postural changes.

  • Tei-index has been reported as one of reliable echocardiographic factors for evaluating cardiac function in human and small animals. In this study, Tei-index were measured and evaluated with other echocardiographic parameters in normal thirteen beagle dogs and thirty-one dogs with mitral valve degeneration. Normal range of Tei index with tissue Doppler obtained at septum and left ventricular free wall was $0.58{\pm}0.07$ and $0.60{\pm}0.07$, respectively. The values between septum and left ventricular free wall did not show significant difference. Tissue Doppler derived tei index showed better reproducibility and significantly lower values than the results obtained by pulsed wave Doppler. Tei index obtained in either method increased with the progression of clinical signs. Therefore, the increase of Tei index in dogs with mitral regurgitation is thought to be an useful factor reflecting left ventricular dysfunction.

  • Body physical technique is to pursuit the dynamic motion by the physical index(PI) and sensory index(SI) on the physical body function. Function of the physical body by the motor condition is organized the dynamic physical system. For the physical motion of signal, we is defined a runout value of the body function by the physical index on the dynamic state. The concept of body physical index was identified the reference of physical index and sensory index by the body technique. As to detect a variation of the body physical technique-runout physical index(BPT-RPI) of the maximum and average and minimum in terms of physical motion, and the dynamic sensory value that was a runout function of the vision variation of the $Vi-{\xi}_{MAX-AVG-MIN}$ with $2.53{\pm}4.85$ units, that was a runout function of the vestibular variation of the $Ve-{\xi}_{MAX-AVG-MIN}$ with ($-0.69{\pm}2.32$)units, that was a runout function of the somatosensory variation of the $So-{\xi}_{MAX-AVG-MIN}$ with ($-1.43{\pm}-1.36$) units. The dynamic physical motion will be to confirm at the variable function of the runout motion for the body function values of dynamic physical index on the BPT-RPI that was identified an evaluation of the physical sensory function by the dynamic physical system. Runout body system was mentioned of a physical body situation by the mild moving and was refer a runout data of dynamic physical nervous index.
