Background
Stroke patients usually experience damage to multiple functions and a long rehabilitation period. Hence, there is a large volume of patient clinical information. It thus takes a long time for clinicians to identify the patient’s information and essential pieces of information may be overlooked. To solve this, we stored the essential clinical information of stroke patients in a blockchain and implemented the blockchain technology using the Java programming language.
Methods
We created a mini blockchain to store the medical information of patients using the Java programming language.
Results
After generating a unique pair of public/private keys for identity verification, a patient’s identity is verified by applying the Elliptic Curve Digital Signature Algorithm based on the generated keys. When the identity verification is complete, new medical data are stored in the transaction list and the generated transaction is verified. When verification is completed normally, the block hash value is derived using the transaction value and the hash value of the previous block. The hash value of the previous block is then stored in the generated block to interconnect the blocks.
Conclusion
We demonstrated that blockchain can be used to store and deliver the patient information of stroke patients. It may be difficult to directly implement the code that we developed in the medical field, but it can serve as a starting point for the creation of a blockchain system to be used in the field.

Abstract PDF

Purpose or Background：This study was performed to identify the usage patterns of oral care products of the patients visiting a National University dental clinic. Materials and Methods：A questionnaire survey was administered to 298 patients visiting the K dental department based in Daegu during the period from December 10, 2005 through January 30, 2006.
Results
：Of total respondents, 42.3% used moderate toothbrush or soft toothbrush, 53.7% replaced their toothbrush every two or three months. Patients with periodontal diseases were aware of 2.1 devices and currently used 1 device out of 10 auxiliary oral hygiene devices recommended by dentist. Spacing patients were aware of 1.8 devices and currently use 1 device out of 3 auxiliary oral hygiene devices recommended by dentist. Patients wearing a fixed dental prosthesis were aware of 2.6 devices and currently used 1.6 devices out of 8 auxiliary oral hygiene devices. Those who received dental implant procedure were aware of 2.9 devices and currently used 1.5 devices out of 6 auxiliary oral hygiene devices. Those with orthodontic problems were aware of 2.7 devices and currently used 1.8 devices out of 6 devices, showing a higher level of awareness on oral hygiene devices. Those wearing dentures recognized 0.6 device and currently used 0.3 device out of 3, showing a lower level of awareness and usage. Of total respondents, 70.2% citied “no knowledge of oral care products” as the reason for not using any oral care product, which was followed by “no one recommended that for me” (15.8%) and “cannot be sure about efficacy” (11.4%). These findings underscore the need for recommending the use of oral care products when a patient sees the dentist.
Conclusion
：Given a significant association between oral health education and the use of auxiliary oral care products, it is important to promote oral health education among dental patients.

Abstract PDF

BACKGROUND
This study was done to better understand patterns, trends and local distribution patterns of malocclusion so that we can provide adequate information to patients, to help make the appropriate diagnosis and therapeutic plans, and to assess the future directions of malocclusion treatment. MATERILAS AND METHODS: Malocclusion patterns, distribution and trends of visiting patients were examined in 993 malocclusion patients who had been evaluated and diagnosed at the Department of Dentistry, Yeungnam University Hospital over a 10-year period from 1995 to 2004. RESULTS: The number of visiting patients per year showed an increasing trend and the visit rate was 1.28 time-higher in females(56.1%) than in males(43.9%). Age distribution showed that the 7-12 year-old group was the largest (36.7%). Geographic distribution showed the majority of patients were from the Dalseo district(28.2%). Angle's malocclusion classification revealed that class III was the largest(38.4%). Crowding was the chief complaint in the highest percentage of patients(33.9%). The therapeutic method used was the fixed appliance in 61% of cases and a combination with extraction in 30.8%. CONCLUSIONS: The availability of dental services can accommodate orthodontic needs adequately as well as obtain reliable quantitative information regarding the characteristics of orthodontic patients.

Abstract PDF

BACKGROUND
This study examined the oral health condition of diabetic patients and evaluated the oral health behavior through a questionnaires survey. In addition, this study provide primary informations for developing a dental health program for diabetic patients. MATERIALS AND METHODS: There were fifty patients with diabetes mellitus or glucose tolerance (controlled by a community health center at Dalsung-Gun in Daegu City and fifty non- diabetic age, gender and location matched control subjects. Data were collected by a direct oral examination and by questionnaires from 100 subjects in July, 2004. RESULTS: The DMFT (Decay, Missing, Filling Teeth) mean values in diabetics were significantly higher than that in non-diabetics (p< 0.05). The decay teeth index and Filling teeth index was similar in the two groups, but the mean Missing teeth index was significantly higher in the diabetics than in non-diabetics. The PI (Periodontal Index) mean values were significantly higher in the diabetics than in the non-diabetics (p< 0.01). There was a significant difference between the diabetics and non diabetics aged in their 50s and 60s, but there was no difference with those aged in their 70s. The oral hygiene status was similar in the two groups. The average number of remaining teeth was significantly lower in the diabetics (16.1+/-10.35) than in the non-diabetics (20.04+/-8.70) (p< 0.05). CONCLUSION: In the diabetic patients, the M component of the DMFT index was found to be higher than the controls. Diabetics lose their teeth mainly due to periodontal disease, which is supported by the increased PI mean values.
