교합안전장치가 측두하악장애 환자의 교근의 휴지기에 미치는 영향
도영환,김진수,최재갑,Do, Young Hwan,Kim, Chin Soo,Choi, Jae Kap 대한안면통증구강내과학회 1987 Journal of Oral Medicine and Pain Vol.12 No.1
The purpose of this study was to evaluate the effect of occlusal splint on the electromyographic silent period duration of masseter muscle in patients with TM disorders. The author measured the Helkimo dysfunction index and masseteric silent period duration before and after 4 weeks splint therapy in 15 patients with TM disorders. The results were as follow: Before splint therapy, the mean durations of masseteric silent period in 15 patients with TM disorders were 50.7msec in left and 50.5msec in right. After 4 weeks splint therapy, the mean durations of masseteric silent period were 25.4msec in left and 26.5msec in right. In the correlation between Helkimo dysfunction index and masseteric silent period duration in before treatment, correlation coefficient is 0.675, p.<0.01. There is statistically significant correlation between Helkimo dysfunction index and masseteric silent period duration. Helkimo dysfunction index was significantly decreased after 4 weeks splint therapy (P<0.01) The masseteric silent period duration was significantly decreased after 4 weeks splint therapy (p<0.01).

구취가 후각인지도 및 methyl mercaptan에 대한후각감지역치에 미치는 영향
도영환,최재갑,안형준,Do, Young-Hwan,Choi, Jae-Kap,Ahn, Hyoung-Joon 대한안면통증구강내과학회 2001 Journal of Oral Medicine and Pain Vol.26 No.4
The purposes of the study were (1) to evaluate the olfactory identification ability in those who have bad breath, (2) to determine the olfactory detection threshold for methyl mercaptan in normal subjects and those who have bad breath, and (3) to evaluate the effect of oral hygiene care on the olfactory detection threshold for methyl mercaptan. Sixteen male subjects with bad breath (male odor group), 9 male subjects without bad breath (male non-odor group), and 10 female subjects without bad breath (female non-odor group) were included for the study. Olfactory identification ability was assessed by administrating the Cross-Cultural Smell Identification Test (CC-SIT), and the olfactory detection threshold for methyl mercaptan was measured by two-alternative forced-choice single-staircase detection threshold procedure in a double-blinded condition. The geometric mean of the last four staircase reversal points of a total of seven reversals is used as the threshold. For the male odor group, after 1 month of intensive oral hygiene care for reducing oral volatile sulfur compounds (VSC) concentration, the olfactory detection threshold for methyl mercaptan was measured again and compared to the initial value. The ANOVA was used to test the group difference of olfactory threshold and olfactory identification ability and the paired t-test was used to test the difference of olfactory threshold between before and after reduction of oral VSC in male odor group. The results were as follows : 1. There was no significant difference in olfactory identification ability among those who have bad breath and normal male or female subjects. 2. The olfactory detection threshold for methyl mercaptan was about 8.4 ppb in normal male and female. 3. There was a tendency that male subjects with bad breath showed a higher olfactory detection threshold for methyl mercaptan when compared to those of no bad breath. 4. The olfactory detection threshold for methyl mercaptan returned to a normal level after 1 month of intensive oral hygiene care for reducing oral VSC.
