이 연구는 우리나라 군 장병이 복무를 하는 과정에서 병영 안의 내무반생활과 병영 밖의 군사훈련생활에서 흡연 양상의 차이와 이와 관련한 구강보건행태와 인식의 변화를 알아보고자 하였다. 이를 위해 2009년 3월 16일부터 6월 16일까지 육군 ${\bigcirc}{\bigcirc}$부대에 복무하고 있는 장병 367명의 설문 응답을 분석하여 다음의 연구결과를 얻었다. 1. 군인의 복무 상황에 따른 구강보건행태를 비교한 결과, 군사훈련생활에서는 내무반생활에 비하여 구강 건강을 적절히 관리하지 못하고 있었다. 칫솔 사용률은 내무반생활에서는 96.2%이었지만 군사훈련생활에서는 72.0%로 감소하였다. 내무반생활을 할 때에는 하루 3회 이상 칫솔질을 한다는 군인이 55.3%이었으나, 군사훈련생활을 할 때에는 29.3%로 크게 감소하였다. 2. 군에 입대한 후 구강예방진료, 구강보건교육, 금연교육을 받은 경험이 없는 군인이 각각 84.1%, 90.7%, 87.9%이었다. 3. 군인의 52.8%가 흡연자이고, 47.2%는 비흡연자이었다. 흡연자의 31.1%는 흡연 후에 아무런 구강건강관리행위를 하지 않았다. 흡연하는 담배 개비의 수는 내무반생활에서는 평균 13.97개비(표준편차 7.51), 군사훈련생활에서는 평균 13.02개비(표준편차 8.36)로서 통계적으로 유의한 차이는 없었다(p=0.109). 4. 흡연자는 칫솔질 횟수와 칫솔질 시간이 적을수록 Pack years가 높은 경향을 보이지만, 통계적으로 유의한 차이는 없었다(각각 p=0.063, p=0.184). 5. 흡연에 대한 구강보건인식을 조사한 결과, 흡연자의 77.9%와 비흡연자의 88.8%가 흡연이 구강건강에 영향을 미친다고 생각하였고(p=0.0095), 흡연자의 52.4%와 비흡연자의 72.5%가 구강건강이 전신건강에 영향을 미친다고 생각하였으며(p=0.0007), 또한 흡연자의 35.8%와 비흡연자의 59.1%가 군대 내에서 금연교육이 필요하다고 생각하였다(p<0.0001). 아울러 전체 대상자의 77.8%와 64.5%가 각각 군대 내에서 구강검진이 필요하고, 구강보건교육이 필요하다고 생각하였으나 이 두 가지의 인식에서는 흡연자와 비흡연자 사이에 통계적으로 유의한 차이는 없었다. 6. 군사훈련생활과 흡연 여부에 따른 칫솔질의 횟수 및 시간을 조사한 결과, 내무반생활에 비하여 군사훈련 생활에서 1회만 칫솔질을 할 확률은 2회 이상 칫솔질을 할 확률보다 9.29배 높았으며(p<0.01), 내무반 생활에 비하여 군사훈련생활에서 1분 이내로 칫솔질을 할 확률은 1분 이상 칫솔질을 할 확률보다 2.19배 높아 통계적으로 유의한 차이가 있었다(p<0.01). 하지만 칫솔질의 횟수와 시간 전체에 대해서는 군사훈련생활 여부와 계급을 보정한 결과, 비흡연자와 흡연자 사이에 통계적으로 유의한 차이가 없었다. 이번 연구를 통하여 우리나라의 군 병사는 내무반에서 생활할 때에 비하여 군사훈련의 생활을 할 때에 자가구강 관리에 어려움을 겪고 있으며, 흡연율이 높지만 군대 내의 금연교육과 구강보건교육은 부족하다는 사실을 확인할 수 있었다. 따라서 군에서는 군 장병이 군 복무를 하는 동안 구강건강이 증진될 수 있도록 의무 환경을 적극적으로 개선해야 할 것이다.

Introduction: Upper aero-digestive tract cancer is a multidimensional problem, international trends showing complex rises and falls in incidence and mortality across the globe, with variation across different cultural and socio-economic groups. This paper seeks some explanations and identifies some research and policy needs. Methodological Approach: The literature illustrates the multifactorial nature of carcinogenesis. At the cellular level, it is viewed as a multistep process involving multiple mutations and selection for cells with progressively increasing capacity for proliferation, survival, invasion, and metastasis. Established and emerging risk factors, in addition to changes in incidence and prevalence of cancers of the upper aero-digestive tract, were identified. Risk Factors: Exposure to tobacco and alcohol, as well as diets inadequate in fresh fruits and vegetables, remain the major risk factors, with persistent infection by particular so-called "high risk" genotypes of human papillomavirus increasingly recognised as also playing an important role in a subset of cases, particularly for the oropharynx. Chronic trauma to oral mucosa from poor restorations and prostheses, in addition to poor oral hygiene with a consequent heavy microbial load in the mouth, are also emerging as significant risk factors. Conclusions: Understanding and quantifying the impact of individual risk factors for these cancers is vital for health decision-making, planning and prevention. National policies and programmes should be designed and implemented to control exposure to environmental risks, by legislation if necessary, and to raise awareness so that people are provided with the information and support they need to adopt healthy lifestyles.

The purpose of this study was to determine the status of dental hygienists in Japan. The study explicated the history, core curriculum, National Examination for Dental Hygienists, work roles of dental hygienists, and workplaces of dental hygienists. This study was based on the government policy report on dental hygienists and the information published by each public institution. The latest statistics presented by the institutions were collected through official websites. The employment information of graduates from Hiroshima University was analyzed based on actual field study. The results of the study revealed that social demand for dental hygienists has steadily increased and policies and education have been revised accordingly. The work roles of dental hygienists have expanded to meet the needs of the treatment and those of public health fields. In line with major policy changes, the educational period has been extended from 1 year to 3 or 4 years, while the mandatory credits for graduation have been established. Licensing examinations were being performed by the local governments since 1948 due to the different situations of dental hygienists in different areas. In 1992, they were converted into a single national examination. The work roles have expanded from assisting dental treatments to health guidance, home care, and perioperative care. Consequently, the number of dental hygienists has increased, especially in healthcare facilities for the elderly. Dental hygienists perform various roles. However, the most essential role is to provide the best oral care services to the patient. The expected role of dental hygienists has expanded in alignment with public healthcare needs and support for the elderly. The government and universities are expected to bring about improvements such as diversifying the channels of education and establishing policies to respond to growing patient needs by cultivating excellent dental hygiene professionals.

Purpose: This systematic review examined the detection of the posterior superior alveolar artery, along with various anatomic characteristics, on cone-beam computed tomography images. Materials and Methods: Studies were identified electronically through the Web of Science, MEDLINE, Scopus, and Embase databases. The quality of the included studies was evaluated using a 5-item binary scale. The detection rate, location, and classified diameter of the posterior superior alveolar artery were estimated as prevalence values. The diameter of this artery, as well as the distances from the artery to the alveolar crest and sinus floor, were estimated as means with associated 95% confidence intervals. Results: Thirty-seven studies were enrolled, with 34 of these included in the meta-analysis. The mean detection rate was 79% (range: 72%-84%), and the mean diameter was 1.06±0.05 mm (range: 0.96-1.16 mm). The posterior superior alveolar artery was located intraosseously in 64% of cases. The mean distance of the artery from the alveolar crest was 16.71±0.49 mm (range: 15.75-17.68 mm), while the mean distance from the artery to the sinus floor was 8.85±0.4 mm (range: 8.05-9.64 mm). Conclusion: According to the findings of this meta-analysis regarding various anatomic characteristics of the posterior superior alveolar artery, severe hemorrhage after damage to this artery during sinus augmentation procedures is not a substantial clinical problem.

Objective: The purpose of this study was to investigate the influence of heritability on the craniofacial soft tissue cephalometric characteristics of monozygotic (MZ) twins, dizygotic (DZ) twins, and their siblings (SIB). Methods: The samples comprised Korean adult twins and their siblings (mean age, 39.8 years; MZ group, n = 36 pairs; DZ group, n = 13 pairs of the same gender; and SIB group, n = 26 pairs of the same gender). Thirty cephalometric variables were measured to characterize facial profile, facial height, soft-tissue thickness, and projection of nose and lip. Falconer's method was used to calculate heritability (low heritability, $h^2$ < 0.2; high heritability, $h^2$ > 0.9). After principal components analysis (PCA) was performed to extract the models, we calculated the intraclass correlation coefficient (ICC) value and heritability of each component. Results: The MZ group exhibited higher ICC values for all cephalometric variables than DZ and SIB groups. Among cephalometric variables, the highest ${h^2}_{(MZ-DZ)}$ and ${h^2}_{(MZ-SIB)}$ values were observed for the nasolabial angle (NLA, 1.544 and 2.036), chin angle (1.342 and 1.112), soft tissue chin thickness (2.872 and 1.226), and upper lip thickness ratio (1.592 and 1.026). PCA derived eight components with 84.5% of a cumulative explanation. The components that exhibited higher values of ${h^2}_{(MZ-DZ)}$ and ${h^2}_{(MZ-SIB)}$ were PCA2, which includes facial convexity, NLA, and nose projection (1.026 and 0.972), and PCA7, which includes chin angle and soft tissue chin thickness (2.107 and 1.169). Conclusions: The nose and soft tissue chin were more influenced by genetic factors than other soft tissues.

The purpose of this study was to investigate the epidemiology of midface fractures. We observed clinically 71 patients with midface fracture who visited the Department of oral and maxillofacial-surgery, Chosun University, Dental Hospital, from 1991 to 1994. The results obtained were as follows. 1. There was the highest age incidence in the third decade(29.6%). 2. There was the highest incidence in the summer(36.6%). 3. The most etiologic factor of midface fracture was traffic accidents(43.6%) and next factor was fall down(38.0%). 4. The highest incidence fracture was zygomatic arch(38.7%) and next fracture was ZMC fracture(31.5%). 5. Most midface fracture was treated within 2 weeks(86.7%). 6. Midface fractures was most frequently combined with mandibular fracture(15.5%), head injuries(14.1%), orthhopedic injuries(8.5), thorax & abdomen(5.6%). 7. The highest complication was the nerve injury(8명), and next complications were infection(3명), epiphora(3명) etc.

We report a case of Hymenolepis diminuta infection in a 2-year-old child living in a suburban area of Catania, Italy. This case was initially referred to us as Dipylidium caninum infection, which was not cured after being treated twice with mebendazole. However, by analyzing the clinical presentation and stool samples we arrived to the diagnosis of H. diminuta infection. The case presented with atypical allergic manifestations which had never been reported as clinical features of symptomatic H. diminuta infection; remittent fever with abdominal pain, diffuse cutaneous itching, transient thoracic rash, and arthromyalgias. The patient was treated with a 7-day cycle of oral niclosamide, which proved to be safe and effective. This case report emphasizes that a correct parasitological diagnosis requires adequate district laboratories and trained personnel. In addition, we recommend the importance of reporting all H. diminuta infection cases, in order to improve knowledge on epidemiology, clinical presentation, and treatment protocols.

Background/Aims: The aim of this study was to assess the association between the number of existing permanent teeth and chronic kidney disease (CKD) in a representative sample of the elderly Korean population. Methods: A total of 2,519 subjects who participated in the Korean National Health and Nutrition Examination Survey were cross-sectionally examined. The number of existing permanent teeth was evaluated by clinical oral examination. CKD was defined based on definition and classification by Kidney Disease: Improving Global Outcomes (KDIGO) 2012 guidelines. Multivariable logistic regression analyses were performed controlling for age, gender, income, education, tooth-brushing frequency, periodontitis, state of dentition, smoking, alcohol consumption, hypertension, obesity, diabetes mellitus, and hypercholesterolemia. Subgroup analyses by age and gender were also performed. Results: The number of teeth was significantly associated with CKD after controlling for all potential confounders (adjusted odds ratio [AOR], 1.67; 95% confidence interval [CI], 1.04 to 2.70 for lower number of teeth; AOR, 1.59; 95% CI, 1.14 to 2.23 for moderate number of teeth). In the subgroup analyses, the association was highlighted in females aged 75 years over (AOR, 2.55; 95% CI, 1.05 to 6.20 for lower number of teeth; AOR, 1.95; 95% CI, 1.01 to 3.80 for moderate number of teeth). Conclusions: Our findings suggest that the number of existing permanent teeth may be associated with CKD among Korean elderly.

Objectives: This cross-sectional study evaluated the prevalence of apical periodontitis (AP) and the technical quality of root canal fillings in an adult Kuwaiti subpopulation using cone-beam computed tomography (CBCT) images. Materials and Methods: Two experienced examiners analyzed 250 CBCT images obtained from Kuwaiti patients aged 15-65 years who attended government dental specialist clinics between January 2019 and September 2020. The assessment followed the radiographic scoring criteria proposed by De Moor for periapical status and the technical quality of root canal filling. Chi-square and Fisher's exact tests were used for statistical analysis, with significance level set at p < 0.05. Results: Among the 2,762 examined teeth, 191 (6.91%) exhibited radiographic signs of AP, and 176 (6.37%) had undergone root canal filling. AP prevalence in root canal-treated teeth was 32.38%, with a significant difference between males and females. Most of the endodontically treated teeth exhibited adequate root canal filling (71.5%). Conclusions: The study demonstrated a comparable prevalence of AP and satisfactory execution of root canal treatment compared to similar studies in different countries.

Purpose: To assess the epidemiology and the clinical features of Glufosinate herbicide in Korea. Methods: Data was prospectively collected during 1 year since August 2005 from 38 hospital in Korea. We analyzed the epidemiologic characters and clinical manifestations of Glufosinate poisoning. In addition, the characteristics of patients with severe central nervous system toxicity were separately analyzed to find poor prognosis relating factors. Results: During study periods, there were 715 persons of poisoning of herbicides and insecticides. 6.3% (45 persons) of the agricultural chemicals poisoning had Glufosinate poisoning. There were 36 cases of suicide attempts and 7 cases of accidental exposure, The major of poisoning route was oral ingestion (44 cases). 28.9 % of the study patients had not toxic symptoms. The most common symptoms were gastrointestinal symptoms relating surfactant irritation. 67.7% of central nervous symptoms occurred lately. 10 persons showed severe central nervous system toxicity. 4 persons of them showed poor outcomes (1 death, 3 hopeless discharged). Complications of respiratory failure and renal failure related with poor outcome. Conclusion: Majority of patients ingested Glufosinate for suicide attempt. 22.2% of patients with Glufosinate poisoning showed delayed serious central nervous system toxicity. Early supportive care of altered mentality may prevent late respiratory complications and improve the outcomes.
