The geriatric population is the most rapidly growing part of the general population, which leads to an increase of chronic conditions and illnesses that will influence both oral and systemic health. The most common chronic diseases in elderly population are arthritis, hypertension, heart diseases, diabetes, and cognitive impairment. Chronic impairments such as visual, hearing, orthopedic, and speech disorders are also prevalent among older adults. All these chronic conditions have potential oral complications and the treatments of systemic diseases also has implications for the maintenance of oral health. Therefore, oral health care professionals should catch up with increasing knowledge in this field and can modify the treatment strategy for older adults. In addition, oral health care professionals should understand the changing need of oral health problems in this age and prepare the future demand.

Fall is the most common cause of trauma in the elderly and a major reason of dental injury. Maxillary anterior region is the most vulnerable area to the traumatic fall. Loss of teeth and adjacent tissue in this area results in maxillofacial defects and inappropriate maxillomandibular relationship. Reconstruction of the loss requires comprehensive and careful planning to fulfill not only functional but also esthetic demand. Prosthetic approach can avoid surgically extensive intervention, reducing both treatment cost and time. This clinical report describes a 78-year-old woman with the loss of teeth and alveolar bone in maxillary anterior region due to a traumatic fall, rehabilitated with a metal-ceramic fixed dental prosthesis using gingival porcelain.

Oromandibular dystonia (OMD) is a form of focal dystonia that affects the masticatory, facial and lingual muscles in any variety of combinations, which results in repetitive involuntary and possibly painful jaw opening, closing, deviation or a combination of these movements. This study aimed to investigate clinical features and treatment type of OMD patients. By retrospective chart review, the study was conducted to consecutive OMD patients who visited a department of Oral Medicine and Orofacial Pain Clinic in a university dental hospital during Aug 2007 to Apr 2010. 78 OMD patients were identified with female preponderance (M:F=1:3.6) and a mean age of 72 years. Their mean duration of OMD was about 10 months. The most common chief complaints at the first visit was jaw ache, followed by uncontrolled, repetitive movement of the jaw and/or oral tissues, pain in the oral region(p=0.000). The most common subtype of OMD was lateral jaw-deviation dystonia, followed by combination and jaw-closing dystonia(p=0.001). While no apparent cause was recognized in over 60% of the OMD patients, peripheral trauma including dental treatment such as prosthetic treatment and extraction was the most frequently reported as precipitating factor(p=0.000). Medication was the 1st line therapy for our patients and anxiolytics such as clonazepam was given to most of them. Based on the results of this study, OMD is the disease of the elderly, particularly of women and causes orofacial pain and compromises function of orofacial region. Some patients considered dental treatment a precipitating factor. Dentists, therefore, should have knowledge of symptoms and treatment of OMD.

노화란 무엇이며 왜 일어나는 것이며, 노화되면 어떻게 되는가에 대하여 많은 연구가 되어 왔지만 아직도 모르는 부분이 많은 것 같다. 우리 몸의 중요기관의 기능은 30세부터 점차 기능이 떨어지면서 늙으면 청년기의 거의 반으로 떨어진다. 늙으면 심장, 폐의 기능뿐만 아니라 활동력도 젊은 때보다 급격히 떨어지며 저작력도 마찬가지로 떨어진다. 본란에서는 주로 청년기이후에 나타나는 조직의 변화를 설명코저 하며, 노화에 따른 구강조직의 변화를 이해함으로서 구강건강을 유지시키고, 노인환자의 성공적인 치료에 도움이 되리라고 생각한다.

Stable posterior occlusal support is crucial for adequate masticatory function and facial aesthetics. In elderly patients over the age of 65, masticatory ability has a significant impact on nutritional intake and overall health. This case report presents a prosthetic treatment of an elderly patient with edentulous maxilla and bilateral posterior edentulous mandible. The upper jaw was restored with a complete denture to establish an ideal occlusal plane, and the three-dimensional positions of the mandibular implants were determined accordingly. The implants were placed through computer-guided implant surgery and were immediately loaded with fixed provisional restorations. The implant-fixed zirconia final restorations were inserted in the lower posterior region, and the occlusal surface of posterior artificial teeth in the upper denture was substituted with cobalt-chrome alloy to resist occlusal wear. The patient's posterior occlusal support and masticatory function were promptly restored through this treatment process, and long-term stability against wear was also obtained.

The purpose of this study is to understand using of antithrombotic agents in clinical settings. The number of patients receiving antithrombotic therapy is increasing in the long term due to the increased prevalence of cardiovascular disease in the elderly. There is a guideline for discontinuation of antithrombotic treatment before dental treatment, but the present study shows that there is a difference from the actual clinical situation. We used an online survey methodology to involve 1000 participants. The questionnaires were asked about general items and Clinical experience such as history of antithrombotic history, experience of complications due to antithrombotics, discontinuation of use, reasons for discontinuing use. The result is as follows. The incidence of delayed bleeding was found to be 55.1%, and discontinuation of antithrombotic therapy before withdrawal was 87.8%. Among respondents 98.3% responded that they stopped antithrombotics because of delayed bleeding and 57.4% responded that they would stop for three to five days. Korean dentists maybe cope with delayed bleeding considering the emotional problem of the patient, the relationship with the patient's physician, and the additional socioeconomic problems.

Purpose: To investigate the relationship between dementia and complete tooth loss on both sides or one side using large demographic data. Materials and methods: A retrospective cohort study was designed using the National Health Insurance Service-Elderly Cohort Database (NHIS-ECD) which was established for people over the age of 60. The experimental group was the complete edentulous cohort, which had a history of treatment for national health insurance covered complete denture on both sides or one side from July 1, 2012 to December 31, 2013. And the control group was the dentulous cohort, which had a history of conservative dental treatment for the same period. All subjects had no history of diagnosis or treatment of dementia during this time. These cohorts were matched 1:1 by age, gender, and place of residence according to the propensity score matching method. Then the incidence of dementia was compared between these cohorts. Results: Compared with those groups, the incidence of dementia was significantly higher in the experimental group (12.13%) than in the control group (9.74%) (P<.05). No clear association between other factors has been identified. Conclusion: The analysis of large-scale demographic data shows that the incidence of dementia is high in complete edentulous patients on both sides or one side.

Autism is a life-long neurodevelopmental disorder characterized by qualitative abnormalities in reciprocal social interactions and patterns of communication. Patients with autism are difficult to manage during dental treatment. Thus they need special consideration like physical restraint, conscious sedation or general anesthesia. A 5-year-old male dental patient with autism was reffered to dental treatment under conscious sedation using intramuscular midazolam that creats anterograde amnesia. Dental procedure using midazolm which cause anterograde amnesia can be effective treatment strategy in autism patient.

This study set out to analyze the relationships between the senior citizens' dental health activities and dental health conditions, to provide basic data to develop a program for their better dental health, and finally to search for the ways to improve their life quality through dental health care. The subjects were 142 senior citizens(58 were male and 84 were female) who were 65 years old or older and visited a dental hospital or clinic in the Seoul metropolitan area from April 17 to April 28, 2006. With the cooperation from the dentists, the investigators examined their dental conditions and conducted one-on-one interviews to collect the information about their demographic characteristics, dental health activities, and subjective dental health conditions. The collected data were analyzed with T-test, ANOVA and Pearson's correlation coefficient using the SPSS WIN 11.5 program. The analysis results were summarized as follows: First, 58 men(40.8%) and 84 women(59.2%) consisted of the subject group, where percentage of the female participants was bigger Those who were aged from 65 to 69 made the biggest age group in the subjects, accounting for 58.5% with 83. Second, those who had three dental caries or less and then didn't treat them or treated them(F) accounted for the biggest percentage with 117(82.4%) and 72(50.7%) respectively. As for the remaining teeth, the biggest number of them(40 subjects, 28.2%) had three or less remaining. Third, it turned out the female subjects had a higher level of dental health activities than their male counterparts(P = 0.00). As for living expenses, those who were paid salary or earned income themselves carried out their dental health activities in a higher level than those who lived on the benefit from the government(p = 0.02). Fourth, the subjects' subjective dental health conditions had negative correlations with their dental caries not treated. And there were positive correlations between their dental caries not treated and dental caries lost and between their dental caries treated and remaining teeth. Fifth, those subjects who earned their living expenses themselves had the most dental caries treated at 5.4(p = 0.02), and there was statistically significant difference with the numbers. Sixth, those subjects who brushed their teeth in their own manner had 11.8 teeth lost(p = 0.05), which was more than the number of those who brushed their teeth in other methods. And there was statistically significant difference among them. The remaining teeth were found most at 17.3(p = 0.00) among those who brushed their upper and lower teeth separately. In addition, those who visited the public health center often had significantly more teeth treated(4.3) than others(p = 0.00).

In this study 240 geriatric patients, aged 60 year and over were evaluated using a questionnaire and oral examination for their oral status, demand and satisfaction of prosthodontic treatment. The followings are the findings : 1. The single main complaint was regarding from the existing removable prosthesis, When the complaints were categorized into larger groups, complaints regarding existing prosthesis were 32% and followed by 30% in caries and endodontic problems. 2. Approximately half of the geriatric patients had 21 or more remaining dentition. This number however diminished with increase in age of the surveyed patient. 3. According to the result from questionnaire, 48% of patients wearing removable prosthesis and 43% with fixed prosthesis were not satisfied with existing prosthesis. Thirty-seven percentages of patients were not satisfied with aesthetics and unable to chew food properly. 4. Seventy-seven percentages of patients requested for new prosthesis and the majority of these patients had complaints of difficulties in chewing and discomfort. 5. Thirty-nine percentages of patients were wearing removable prosthesis. More complete dentures were found on maxilla and partial dentures on mandible.
