Purpose: This study was performed to investigate a correlation among oral hygiene habits,dryness of mouth, and self-perceived oral malodor and therefore to find out self-care methodswhich could be a help to reduce oral malodor. Methods: A survey of 296 dental undergraduate students of School of Dentistry, Pusan NationalUniversity, who wrote consents voluntarily and participated in this study, was conducted usinga questionnaire consisting of 17 questions and analyzed to investigate a correlation amongoral hygiene habits (frequency of tooth brushing, water gargling, and drinking water, etc.),dryness of mouth indicating the amount of salivary secretion, and self-perceived oral malodor. Results: There was no significant correlation between mechanical cleaning factors and selfperceivedoral malodor. The factor showing a strong correlation with severe self-perceived oralmalodor was dryness of mouth (p=0.000). Conclusions: There was no correlation between mechanical cleaning habits and self-perceivedoral malodor. Participants who felt self-perceived oral malodor more tended to have rathergood mechanical cleaning habits. The factor showing a strong correlation with severe selfperceivedoral malodor was dryness of mouth. Therefore trying to increase salivary secretion isconsidered to be a help to reduce self-perceived halitosis.

목적 : 측두하악장애 치료에서 기존의 다른 치료 방법이 동일한 경우, 초진 시에만 서면으로 된 주의사항을 보고 읽어주며 교육했을 때와 내원 시마다 자가평가 설문지를 통한 반복적 주의사항 교육을 시행했을 때의 치료효과 차이를 알아본다. 방법 : 2012년 10월부터 12월까지 부산대학교치과병원 구강내과에 내원한 측두하악장애 환자(n=62, 실험군)와 2011년 10월부터 12월까지 내원한 측두하악장애 환자(n=156, 대조군)를 대상으로 하였다. 측두하악장애로 진단된 후 내원횟수, 치료방법을 동일하게 시행한 환자를 표본으로 선정하였다. 실험군은 자가평가 설문지를 통한 반복적 주의사항 교육을 초진일, 2주 후, 4주 후 시행하였고 또한 Pain NRS(Numerical Rating Scale), MCO(Maximum comfortable opening), Noise NRS, LOM(Limitation of Mouth opening) NRS를 조사했다. 대조군은 초진 시만 주의사항 교육을 하였고, 실험군과 동일 항목을 조사하였다. 실험 군과 대조 군간의 조사항목의 1,2회 내원 시 차이와 1,3회 내원 시 차이를 전체, 연령, 성별, 골 변화 유무별로 독립표본 T검정을 시행하였다. 결과 : 반복적인 주의사항 교육으로 인한 주의사항 준수는 약물치료를 중단한 후에도 MCO개선을 유지 및 증가 시켰다(p=0.001). 반복적인 주의사항 교육으로 인한 주의사항 준수로 인한 MCO개선 효과는 남자에서 두드러졌으며(p=0.001) 젊은 연령에서 크게 나타났다(p=0.004) 결론: 측두하악장애 환자의 행동조절을 위한 주의사항 교육은 반복적으로 시행할수록 치료효과가 크게 나타난다. Aim : The purpose of this study was to investigate the hypothesis that treatment with self-checking behavior management program was valuable in the management of temporomandibular disorders compared with a existing method treatment group. Methods : All participants who are diagnosed with temporomandibular disorders were treated with medication and physical therapy. They came into the clinic at intervals of two weeks, three times. The signs and symptoms were assessed investigating Pain NRS(Numerical Rating Scale), MCO(Maximum comfortable opening), Noise NRS, LOM(Limitation of Mouth opening) NRS at every visit. Experimental group received instructions repeatedly by using self evaluation questionnaire. Control group was educated once at the beginning of treatment. The difference Pain NRS, MCO, Noise NRS, LOM NRS between first and second visits, first and third visits were estimated.. Result :Experimental group showed greater improvement on MCO difference after stopping medication(p=0.001). This improvements were prominent in the male(p=0.001) and the first or second decade of the patients(p=0.004). Conclusion : The present study showed that there was better result when educating repeatedly with using self evaluation questionnaire than educating once at the beginning of the treatment.

본 연구는 부산 청소년의 측두하악장애의 양태, 증상과 진단명에 대한 변화를 알아보기 위해 다음과 같은 조사를 시행하였다. 2000년과 2008년에 내원한 12-19세 청소년의 측두하악장애 분석검사를 조사하여 성별, 나이, 악관절환자를 위한 조사 설문지, 원인, 진단명, 장치치료여부, 치료종결시 Pain NAS 항목에 대한 자료를 정리, 분석하였다. 1. 2000년도에 비해 2008년도의 청소년 내원 환자수가 증가했다. 이 중 남자 청소년의 비중이 현저히 증가했다. 2. 2000년도에 비해 2008년도의 청소년이 개구제한보다는 소리를 주소로 내원하는 경우가 많아졌으며 악습관 중 이갈이, 이악물기, 턱괴기, 수면의 질 저하 비율이 유의하게 증가하였다. 3. 골관절염은 유의하게 증가하였고 과운동은 유의하게 감소하였다. 4. 골관절염 환자에서2000년도에 비해 2008년도 10대 청소년의 남자비율이 현저히 증가하였다. 턱괴기, 이갈이, 이악물기 악습관을 가진 환자 중 지난 10년간 공통적으로 골관절염이 유의하게 증가한 것으로 미루어 턱괴기, 이갈이, 이악물기가 골관절염 발병 증가와 유의한 관계가 있을 것으로 추측할 수 있다. A retrospective study was conducted to determine the patterns of Temporomandibular Disorder(TMD) among adolescents (12-19 years) over last ten years. 174 patients who had visited the Oral medicine of Pusan National University Dental Hospital in 2000 and 491 patients in 2008 were found on chart review. The results obtained were as follows : 1. The number of adolescent patients was significantly increased in 2008 than in 2000, especially in male. 2. Bruxing, clenching, holding habits and bad sleep hygiene were highly increased more in 2008 than in 2000. 3. Osteoarthritis was significantly increased in 2008 than in 2000 and anterior disc dislocation without reduction was slightly increased. 4. The ratio of male to female adolescent patients with osteoarthritis was remarkably increased. Among the patients who had holding, bruxing, clenching habits, significantly increased osteoarthritis found to be common. This could imply holding, bruxing, clenching habits are prominently associated with increasing risk of developing osteoarthritis.

옥수민,김진화,김지수,정은교,박양미,전혜미,허준영,안용우,유선녕,박혜련,김경희,안순철,정성희 연세대학교의과대학 2020 Yonsei medical journal Vol.61 No.4

Purpose: Osteoarthritis (OA) of the temporomandibular joint (TMJ) elicits cartilage and subchondral bone defects. Growth hormone (GH) promotes chondrocyte growth. The aim of this study was to evaluate the efficacy of intra-articular injections of GH to treat TMJ-OA. Materials and Methods: Monosodium iodoacetate (MIA) was used to induce OA in the TMJs of rats. After confirming the induction of OA, recombinant human GH was injected into the articular cavities of rats. Concentrations of GH and IGF-1 were measured in the blood and synovial fluid, and OA grades of cartilage and subchondral bone degradation were recorded by histological examination and micro-computed tomography. Results: MIA-induced OA in the rat TMJ upregulated insulin-like growth factor-1 (IGF-1) rather than GH levels. GH and IGF-1 concentrations were increased after local injection of GH, compared with controls. Locally injected GH lowered osteoarthritic scores in the cartilage and subchondral bone of the TMJ. Conclusion: Intra-articular injection of GH improved OA scores in rat TMJs in both cartilage and subchondral bone of the condyles without affecting condylar bone growth. These results suggest that intra-articular injection of human GH could be a suitable treatment option for TMJ-OA patients in the future.

측두하악장애, 골관절염 환자의 교정치료; 교정 시 고려사항

Signs and symptoms of Temporomandibular disorder(TMD) may appear before, during, or even after orthodontic treatment. It is recommended for all patients who visit clinics for orthodontic treatment to check the presence or absence of symptoms through a simple TMD evaluation and inform them of the results in advance. Also, modifying the orthodontic treatment strategy depending on the presense of TMD is beneficial to patients. In patients with weak physiologic tolerance who initially have no signs or symptoms of TMD, signs or symptoms may develop if the temporomandibular joint complexes fail to adapt to the changes following orthodontic treatment. To this end, periodic TMD inspections should be continued throughout treatment period and appropriate medical interventions for the temporomandibular joint should be performed. In addition, patients should be informed that it may be necessary to receive TMD treatment after stopping orthodontic treatment when TMD symptoms occur during orthodontic treatment, and that orthodontic treatment can be resumed when symptoms improve.

Dehydration as an Etiologic Factor of Halitosis: A Case-Control Study

옥수민,정성희,이창형 대한안면통증∙구강내과학회 2021 Journal of Oral Medicine and Pain Vol.46 No.4

Purpose: Salivation is considered to be an important factor in the control of halitosis, and the amount of salivation has been shown to be closely related to the level of hydration. The purpose of our study was to evaluate the relationship between dehydration and halitosis. Methods: Twenty healthy young females with no dental problems were recruited. All participants were induced to become dehydrated and then over-hydrated. After inducing each hydration state, the severity of hydration and halitosis factor (organoleptic scores, amounts of resting and functional saliva, gas examinations, and tongue coatings) were measured. Hydration statuses were graded as dehydration, normal, or over-hydration according to urine osmolality. This was a cross sectional study with a cross over design. Results: The dehydrated status was associated with higher organoleptic scores than the normal or over-hydrated status (1.75±0.75 vs. 0.87±0.63, and 0.65±0.53, respectively. p0.05). (CH3)2S (r=0.410, p=0.009) showed a moderate positive correlation with dehydration status. The resting salivation rates were relatively lower for the dehydrated status than for the normal or overhydrated status (p>0.05), and tongue coating results were also higher for the dehydrated status (p>0.05). Conclusions: Dehydration status appears to be positively correlated with a low resting salivation rate and high portable gas chromatography results. This shows that dehydration might be an etiologic factor of halitosis.

옥수민,김경희,허준영,안용우,정성희 대한안면통증∙구강내과학회 2015 Journal of Oral Medicine and Pain Vol.40 No.2

Purpose: The purpose of this research was twofold: to compare the short-term efficacy of onceoffeducation versus repetitive education (RE) of patients suffering from temporomandibulardisorders (TMDs) and to determine whether there was any correlation amongst patient demographics,recommendation adherence degree and pain levels. Methods: A total of 848 patients with TMDs were enrolled. The control group consisted ofpatients who received a standard conservative treatment (STD) over at least 6 visits with educationprovided only during the first visit. The experimental group consisted of patients whoreceived STD but had also been given RE (STD+RE). The RE was delivered through a standardizedself-assessment questionnaire (SAQ) that was completed by the patient during each visit. Pain, which included maximum comfortable opening (MCO) of the mouth and limitation ofmouth opening (LOM), was compared between the two groups. Behavior pattern and reportedpain level changes in the group who used the SAQ were also analyzed. Results: The LOM was significantly improved in all of the experimental group patients (especiallyin females under 30 years of age, p<0.05). The MCO was significantly higher in females(p=0.029). All of the patients displayed improvements in their habits following RE, which resultedin a strong correlation with pain reduction. Adhering to the recommendations regardingquestions 14 and 15 of the SAQ appeared to have the greatest effect on pain reduction. Conclusions: These results clearly demonstrate that RE is more effective than once-off educationfor TMD patients who are female or under 30 years of age.

This study was conducted to investigate the relationship between systemic diseases and oral malodor. The author measured the volatile sulfur compound(VSC) of the patients who visited Pusan National University Health Promote Center for a comprehensive medical testing. The patients were examined gingival bleeding on probing, CPI index, tongue coating. Their systemic diseases were diagnosed by the specialist. 182 patients consisted of 112 males and 70 females. In this study, Oral $Chroma^{(R)}$ was used to measure oral malodor. This equipment could measure the concentration of intraoral VSC (hydrogen sulfide, methyl mercaptan, dimethyl disulfide). All data were analylized using Statistical Package for the Social Science $12.0^{(R)}$. The result of this study was the followings. 1. There was significant difference of numbers of patient who visited health care center according to the VSC concentration level and the Community Periodontal Index, bleeding on probing, tongue coating. 2. The subjects with hyperlipidemia showed the high level of $CH_3SH$ concentration (p=0.036). The concentration of $H_2S$ tends to be high in the group with abnormal findings on pulmonary fuction test(p=0.086). The concentration of $CH_3SH$ in the groups with abnormal findings on lipid profile test(p=0.130) and bone mineral density test(p=0.099) and abdominal ultrasonograpy(p=0.088) tends to be higher than the other group. 3. The concentration of $(CH_3)_2S$ in the group with abnormal findings on blood pressure test(p=0.113), hepatitis B virus serology(p=0.069), Abdominal ultrasonograpy(p=0.091) tend to be higher than the other group.
