Purpose: This study aims to examine correlation between temporomandibular disorder and oral habits that have been known to cause temporomandibular disorder with both male and female undergraduates. Methods: To figure out correlation between temporomandibular disorder and oral habits, a survey was conducted to 500 students of two universities located in Daegu Metropolitan City and Gyeongsangbuk-do, and excluding the ones unreliably answered or indicating errors, total 427 (85.4%) out of 500 questionnaire sheets were used for final analysis. Results: Female students showed higher prevalence rates than male students in temporomandibular joint pain and temporomandibular joint clicking, and students having the lip biting habit, tongue thrust habit, or bruxism habit indicated a higher prevalence rate of temporomandibular joint pain than normal students. Also, students having the tongue thrust habit indicated a significantly higher prevalence rate of temporomandibular joint clicking than normal students not having it. And about trismus, students having the bruxism habit showed a significantly higher prevalence rate than normal students not having it. Conclusion: The findings imply that oral habits like lip biting, tongue thrust, or bruxism are closely related with temporomandibular joint pain, tongue thrust influences temporomandibular joint clicking, and bruxism does affect trismus.

Introduction: The incidence of oral premalignant and malignant lesions is on the rise due to an increased number of people taking in tobacco and alcohol related habits. Material and Methods: 1028 patients with tobacco, alcohol and areca nut habits attending our Department of Oral Medicine and Radiology formed the study sample. An interviewer based questionnaire was used to record the habit details. All the patients were then examined clinically for the presence of lesions. Chi square and Fisher exact tests were used to assess the statistical significance of the study parameters. Results: Males had a higher prevalence and comprised 87.9% of the sample. The commonest habit in this study sample was smoking (39.2%) followed by smokeless tobacco use (28.1%). Out of the 1028 patients with habits 40% had no clinically detectable changes in their mucosa. Of the mucosal changes leukoplakia (14%) was the commonest. Conclusions: This study provided information about the habit trends in the patients visiting this institution. The study may serve as a useful tool in educating the patients about the deleterious effects of oral tobacco, alcohol and betel exposure.

Purpose: This study is intended to survey male and female university students to see if there is correlation between temporomandibular disorder and oral habits known to cause temporomandibular disorder. Methods: A survey was conducted to 400 male and female university students attending two universities located in Daegu Metropolitan City and Gyeongsangbuk-do to examine if there is correlation between oral habits and temporomandibular disorder. Among total 400 questionnaire sheets, 334 (83.5%) sheets were used for final analysis except for those unreliably answered or containing error. Results: Female students showed a higher prevalence rate of temporomandibular joint pain than male students, and those having the habit of resting jaw on hand indicated a higher prevalence rate of temporomandibular joint pain, temporomandibular joint clicking, or trismus than normal students not having it. Also, those having the habit of tooth clenching showed a significantly higher prevalence rate of temporomandibular joint pain or temporomandibular joint clicking than normal students not having it. Conclusion: It can be concluded that the habit of resting jaw on hand is closely related with temporomandibular disorder like temporomandibular joint pain, temporomandibular joint clicking, or trismus, and the habit of tooth clenching is significantly correlated with such symptoms as temporomandibular joint pain and temporomandibular joint clicking.

Objectives: The purpose of this study is to identify the perceived symptoms of oral and temporomandibular joint disorders in adults and to analyze the factors affecting subjective symptoms of temporomandibular joint disorders. Methods: 249 adults over 20 years old who had subjective symptoms of temporomandibular joint disorders were surveyed and analyzed. Independent t-test and ANOVA test were used to examine the relationship between oral habits and temporomandibular joint disorder according to general characteristics. $Scheff{\acute{e}}$ test was used for post-hoc analysis. Multiple regression analysis was conducted to examine the factors affecting oral habits and temporomandibular joint disorder. Results: First, the factors affecting oral and habitual behaviors were married (p<0.05) and monthly income between 1 million~1.9 million won (p<0.001), higher temporomandibular joint disorder (p<0.01) And the degree of habit was increased. Second, the factors affecting temporomandibular joint disorder were increased in occupation (p<0.05) and the degree of oral habit (p<0.01). Conclusions: In conclusion, it was confirmed that oral habit influences temporomandibular joint disorder. Especially, it is suggested that prevention and promotion of temporomandibular joint disorder are needed to recognize the removal of oral habits.

본 연구에서는 치아교모도에 의한 연령감정법을 이용하여 측두하악장애환자의 치아연령을 일반 정상인과 비교하고, 측두 하악장애환자의 구강습관이 치아교모에 미치는 영향을 조사하고자 하였다. 단국대학교 치과병원 구강내과에 측두하악장애를 주소로 내원한 환자 65명을 실험군으로 하고, 측두하악장애증상이 없는 정상인 22명을 대조군으로 하였다. 문진 및 설문조사를 통해 대상자의 구강습관을 조사하였으며, 임상 및 방사선검사후 치아교모도를 조사하여 치아연령을 산출하였다. 실험군과 대조군의 치아교모도의 차이 및 각각의 구강습관이 치아교모에 미치는 정도를 분석하기 위해 t-test 및 one-way ANOVA, multiple comparison t-test를 이용하였다. 연구 결과 대조군에 비해 실험군의 치아교모도가 유의성 있게 증가했으며, 조사된 구강습관중 이갈이, 이악물기, 식사습관(단단하고 질긴 음식)순으로 치아교모도에 영향을 주었다. 따라서, 측두하악장애환자의 연령감정시 증가된 치아교모도에 의해 나타날 수 있는 실제 연령과의 차이를 고려해야 한다. 특히, 20-30대의 연령감정시에 측두하악장애환자의 경우 약 3.5세, 이중 특히 이갈이의 습관이 있는 경우에는 약 5.3세의 감정연령의 증가가 있을 수 있음을 감안해야 한다. 또한, 측두하악장애환자는 일반 정상인보다 치아 교모가 심한 경향이 있고 이는 치아와 턱관절에 더 많은 하중이 가해지고 있음을 의미하므로 측두하악장애환자의 치료시에는 반드시 이러한 요인을 제거하는 치료술식을 병행해야 할 것으로 사료된다.

The aim of the present study was to investigate a relation between occlusal wear area and occlusal contact patterns. For the purpose, occlusal wear area were measured in 58 dental students and in 129 patients with temporomandibular disorders(TMDs) from dental casts. Teeth used in this study were from canine to second molar on both sides in upper arch, totally ten. Occlusal wear area on casts was marked by pencil and photocopies, and then, the area was measured with planimeter. Occlusal relation was clinically examined with regard to Angle's classification, chewing side preference, lateral guidance pattern and bruxing and/or clenching habit. T-Scan, electronic occlusal contact analyzer, was used to record occlusal contact number, contact force, contact time and occlusal balance that is TLR(total left-right statistics) during tooth contact. All measurement were repeated 3 times and the average value was used for data processing. The obtained results were as follows : 1. Mean value of occlusal wear area did not differ significantly between dental students and patients. 2. There ws not significant difference in wear area between chewing side and non-chewing side in both groups. 3. Occlusal wear area was significantly increased with age in both groups. 4. Three subgroups divided by Angle's classification did not show any difference in occlusal wear area among them, but three subgroups divided by lateral guidance pattern showed slightly significant difference between canine guide subgroup and group function subgroup in patients. Occlusal wear ares\a in group function subgroup wear larger than canine guide subgroup. 5. Mean value of wear area in patients with bruxing and/or clenching habit did not differ from those in patients without such habit. 6. Correlationship among items related to occlusal contact pattern were highly consistent and significant in dental students and only one item significantly correlated with occlusal wear area was tooth contact time.

Background: In India smokeless tobacco users account for 25.9% of total tobacco use, Gutkha being the most common form. This study evaluated the association between serum lipid profile and Gutkha use as an early diagnostic and/or prognostic indicator for oral submucous fibrosis (OSMF) and oral cancer (Oral Ca) in non-smokers and non-alcohol consumers. Materials and Methods: A total of 163 participants were recruited from two sites in India. Participants were divided into four groups: individuals without any Gutkha chewing habit and without any oral lesions (control group), individuals with Gutkha chewing habit but without any oral lesions (GWL), patients with a confirmed clinical diagnosis of OSMF, and patients with a confirmed diagnosis of Oral Ca. Mixed linear modelling (MLM) was conducted to detect the change in mean serum lipid levels among four groups. Results: The sample consisted of 69% males and 31% females. Results of MLM show an inverse relationship between serum lipid levels in OSMF, and Oral Ca groups when compared to the control group. Conclusions: The results of our study demonstrated that GWL, OSMF and Oral Ca patients had lower serum lipid levels. Low serum lipid levels could be an indicator of initial neoplastic changes in oral cancer.
