This study investigates the effects of mental health and daily oral habits on temporomandibular joint symptoms. The study was conducted from September 1 to 30, 2019, enrolling a total of 402 young adults. We determined that mental health levels of anxiety, depression, and social maladjustment are significantly different, depending on life satisfaction (p<0.001), subjective health status (p<0.001), and trauma (p<0.01). Treating jaw joints exerted a significant difference in social maladjustment (p<0.05). Temporomandibular joint symptoms are significantly higher among women (p<0.05), drinkers (p<0.01), trauma (p<0.01) and jaw joint treatment patients (p<0.001). Mental health levels (p<0.001), oral habits (p<0.001), and temporomandibular joint symptoms (p<0.001) are all positively correlated. In addition, oral hygiene has the greatest influence on temporomandibular joint symptoms of trauma. Furthermore, factors experienced during treatment of the jaw joints also affect the temporomandibular joint symptoms. We conclude that it is imperative to improve oral health and malpractice in treating jaw joint disorders, and also develop a program that effectively improves jaw joint health, by combining mental health counseling and daily lifestyle improvements.

Tobacco smoking is a major risk factor of systemic health and also impairs oral health, which is related to development of oral cancers, periodontitis, delayed wound healing, tooth loss, failure of implant, etc. Aside from smoking, many other risk factors can be related to oral health and long-term effects of smoking on salivary flow and taste threshold are still in controversy. Authors considered dental students to be an appropriate group with good oral hygiene for a long-term study to reveal effects of smoking on oral health. This study was performed to compare smoking patterns and current oral health conditions between smokers and nonsmokers in dental students prior to long-term evaluation. 192 volunteers (85.7%) of 224 male dental students in Dankook University were evaluated through questionnaires and clinical examination in 2010. Questionnaires included smoking pattern, alcohol use, nicotine dependence, preventive care, psychological profile and clinical examinations comprised assessment of teeth or periodontal status, nicotine pigmentation, salivary flow, electrical taste thresholds and halitosis. From the study, (current) smokers were older, and drank more frequently with more alcohol intake compared to former smokers and nonsmokers(p<0.05). There was no significant difference among them in salivary flow rate, halitosis and electrical taste threshold. However, there was significant difference in DMFT rate, periodontal treatment need, nicotinic pigmentation between smokers and nonsmokers(p<0.05), irrespective of their levels of preventive care. The smokers in this study, who are young dental students with relatively shorter duration of smoking, less use of cigarettes and low level of nicotine dependence, did not reveal significant impairment of oral health. However, their oral health was found to be relatively impaired compared to nonsmokers', which suggests negative effect of smoking on the oral health and a need of smoking cessation.

Purpose: The purpose of this study was to assess the association between sleep disturbances and personality type. Methods: Five hundred twenty-four college students in Gyeonggi-do completed the Myers-Briggs Type Indicator (MBTI) and a questionnaire and collected data were analyzed by SAS 9.4 program. Results: Extroversion (E) type, sensation (S) type, and perceiving (P) type had significantly higher prevalence of insomnia than introversion (I) type (p<0.05), intuition (N) type (p<0.05), and judging (J) type (p<0.001), respectively. Tooth grinding, snoring and insomnia appeared to occur more frequently in feeling (F) type than in thinking (T) type. Tooth clenching, tooth grinding and snoring seemed to occur more frequently in S type than in N type. Insomnia occurred significantly the most frequently in sensation-feeling (SF) type (p<0.05). Tooth grinding and snoring seemed to occur the most frequently in SF type. A significantly increased percentage of sensation-perceiving (SP) type demonstrated insomnia (p<0.001). Tooth clenching, tooth grinding and snoring seemed to occur the most frequently in sensation-judging (SJ) type. Sensitive or nervous type of personality had significantly higher prevalence of insomnia than relaxed or general type of personality (p<0.01). A significantly increased percentage of subjects with bad general health status showed insomnia (p<0.0001). Tooth clenching and snoring seemed to occur the most frequently in subjects with bad general health status. A significantly decreased percentage of normal weight subjects demonstrated tooth grinding (p<0.05). Snoring occurred significantly the most frequently in overweight subjects (p<0.001). Tooth clenching showed significant correlation with stress (p<0.01) and personality (p<0.05). Snoring showed significant correlation with stress (p<0.05) and body weight (p<0.001). Insomnia showed significant correlation with stress (p<0.0001), personality (p<0.01), and general health status (p<0.0001). Conclusions: Sleep disturbances including tooth clenching and insomnia were associated with personality type and it is desirable to manage them considering personality type.

This study was to figure out the influence of oral health behavior and periodontal status on their OHIP-14. Explained to 255 people who visited the scaling center of Dental Hygienics of a college in Gyeongbuk from March 7th to June 13th 2014 and it was agreed to perform. Result of dental plaque and calculus rate of those with no TBI were high; the less frequent do they teeth brushing the higher were their rate of dental plaque, bleeding and calculus, while their OHIP-14 was low. The rate of calculus of whom with no education on dental floss use and who do not use dental flosswas high. The more powerful for those with higher rate of dental plaque; while the lower was the rate of calculus the higher was OHIP-14. Therefore, the more do they brush their teeth and the lower are the rate of their calculus, the more positively has it been figured out to influence on the quality of their life of oral health. Consequently, public health program should be developed to educate them on the necessity of scaing on a regular basis and the cause calculus of occurrence, as well as a media through which they can easily participate in the program.
