This study was designed to investigate the effect of Gibson's smile exercise. The author took the smile photographs of 35 university students who appeared unnatural smiles though they had good dentition or well restored state of their teeth. The author explained Gibson's smile exercise and they trained their perioral muscles during 4 weeks at home. The smile photographs were taken at regular intervals, before the smile exercise, 2 weeks after and 4 weeks after the smile exercise. And then, esthetic smile scores were estimated by 10 appraisers who were dentists. Some questionares were taken aftersmile exercise. And acquired scores were analized statistically using the SPSS program. The results obtained were as follows. 1. The smile scores of 2 weeks after and 4 weeks after the smile exercise were higher than before the smile exercise. 2. The smile scores of 4 weeks after the smile exercise were higher than 2 weeks after the smile exercise. 3. The smile scores of the group interested in smiles were higher than the group not interested in smiles at 2 weeks after and 4 weeks after the smile exercise, but before the smile exercise there was no difference between two groups.

There has been a lot of research into the essence of the smile, but so far just a few studies have been done on the relationship between personality and smile. On the assumption that smile aesthetics are closely related to individual physical condition and psychological state, this study investigated the correlation between personality factors and smile scores. The Personality Factor Questionnaire test was administered to 60 university students (male : 30, female : 30) who have no teeth missing, no experience of orthodontic or prosthodontic treatment and good dentition. Then, portraits were taken in a full smile. Esthetic smile scores were estimated by 10 appraisers who were dentists. These scores were analyzed statistically using the SAS program. The following results were obtained. 1. Personality factors of Warmth, Stableness, Surgency, Boldness, Untroubled-adequacy, Group-dependence, Relaxation, Extraversion, Low anxiety were positively correlated to the aesthetic level of smile. 2. For females, personality factors had greater influence on smile aesthetics, whereas male smile aesthetics were less influenced by personality factors.

This study was designed to investigate the correlation between the degree of knowledge in regards to the importance of oral health and the smile scores as well as the correlation between their actual oral conditions and smile scores. The author surveyed the knowledge and the actual oral health condition of the subjects, 150 high school students (80 males and 70 females), and their frontal pictures were taken when they had full smiles. After evaluation of the smiles of the subjects by five dentists, the results were analysed. This study showed that there was neither a correlation between the smile score and the knowledge of oral health nor the actual oral condition. The investigation showed that the actual oral condition and care was performed well even if there were some wrong answers in the questionnaire, which asked about proper oral health. In conclusion, the smile could be related to the repetition of the habit of smiling rather than being related to the knowledge of oral health or their actual oral condition.

Background: This study aimed to evaluate the patient's pain and quality of life after suture removal at either 3 or 7 days following the bilateral surgical extraction of impacted lower third molars. Methods: This study was a prospective, randomized controlled clinical trial carried out in 30 patients, who acted as their own control. Each patient required the bilaterally impacted mandibular third molars to be extracted. The impacted teeth were removed and the wound margins were approximated and sutured with black braided silk. The suture material was removed on day 3 on one side and on day 7 on the other. Each participant was asked to complete a questionnaire after the removal of the suture material on each designated day. Results: Regarding overall clinical symptoms, the mean VAS scores of male and female participants on day 3 were not significantly different from those on day 7. A significant difference was found in female participants, in that overall daily activity was better on day 7. There were significant differences in the ability to smile and laugh in both sexes and the ability to chew in the male participants was better on day 7. Conclusions: There were no significant differences in the patient's pain and quality of life between suture removal on day 3 or on day 7 following surgery to remove impacted lower third molars.

Objectives: The coronavirus disease 2019 (COVID-19) pandemic has led to a decrease in face-to-face classes worldwide, affecting the mental health of children and their parents. The global pandemic has increased children's overall use of electronic media. This study analyzed the effect of children's screen time on problematic behaviors during the COVID-19 pandemic. Methods: A total of 186 parents from Suwon, South Korea, were recruited to participate in an online survey. The mean age of the children was 10.14 years old, and 44.1% were females. The questionnaire included questions on children's screen time, problematic behaviors, and parental stress. Children's behavioral problems were evaluated using the Behavior Problem Index, whereas the Parental Stress Scale was used to estimate parental stress. Results: The mean smartphone usage frequency of the children was 5.35 days per week, and the mean smartphone screen time was 3.52 hours per day. Smartphone screen time (Z=4.49, p<0.001) and usage frequency (Z=2.75, p=0.006) were significantly correlated with children's behavioral problem scores. The indirect effect of parental stress on this relationship was also statistically significant (p=0.049, p=0.045, respectively). Conclusion: This study suggests that children's smartphone screen time has affected problematic behaviors during the COVID-19 pandemic. Furthermore, parental stress is related to the relationship between children's screen time and problematic behaviors.

Objectives : This study analyzed psychological aftereffects and made comparisons between victims who were either sexually assaulted or molested using the Minnesota Multiphasic Personality Inventory-2(MMPI-2). Methods : The participants were adult women who visited the Busan Smile Center within 6 months following sexual assault. This study categorized the participants according to types of sexual violence and then identified their social demographic features and characteristics. Student's t-tests were carried out to compare the MMPI-2 results between the sexually assaulted group and sexually molested group. Chi-square tests were also conducted to compare between participants who scored above 65T. Results : Among the 55 participants, 32 were sexually assaulted; 23 were sexually molested. Significant differences between the two groups were found in the following scales: F, F(B), F(P), Pt, Sc, Ma, RC6 and PSYC. Moreover, the number of participants with higher scores in the Pa, Pt, Sc, RC6, and PSYC scales in the sexually assaulted group was significantly higher than in the sexually molested group. Conclusions : Both groups of victims may commonly suffer beyond the moderate level of depression and anxiety in the post-case term. In addition, the sexually assaulted group seems to suffer relatively more from panic and psychological pain than the sexually molested group does.

Objectives : According to the recent Korean National Police Agency report, rape victims were 17.1%, but sexual molestation victims were more than the rape victims by 78.0%. Despite many international reports about the occurrence of severe psychiatric symptoms in sexual molestation victims, there is no domestic research. Therefore in this study, we investigated psychiatric symptoms of sexual molestation victims, and we also compared it with psychiatric symptoms in rape victims. Methods : 58 women who visited Busan Smile Center within 3months after sexual violence were the study subjects. Questionnaire about sociodemographic and sexual violence related characteristics were retrospectively investigated. Of the psychiatric symptoms, Beck Depression Inventory(BDI), Beck Anxiety Inventory(BAI) for severity of depression and anxiety, and Impact of Event Scale-Revised(IES-R) to check the presence of posttraumatic stress disorder(PTSD) symptoms were used. Results : Of 58 sexual violence victims, sexual molestation victims were 36(62.1%) and rape victims were 22(37.9%). In sexual molestation victims, 80.6% had more than moderate severity of depression, 83.3% had more than moderate severity of anxiety, and 94.4% had significant scores at PTSD screening test. Compared with rape victims' psychiatric symptoms(each 95.5%, 95.5%, 95.5%) there were no significant difference. Conclusions : The majority of sexual molestation victims were also accompanied by depression, anxiety and PTSD symptoms as rape victims. There results suggest that appropriate assessment and early treatment for psychiatric symptom must be made in the early stage of injury in sexual molestation victims.
