  • This study intended to examine the health status and quality of life among the elderly patients who stayed in geriatric hospitals for a long period of time. The study involved 222 elderly who were older than 65-year-old, an oral examination was conducted in 10 geriatric hospitals located in the metropolitan area and Chungcheong-do. Cross-tabulation, one-way ANOVA, t-test, and Stepwise multiple regression were performed for analysis. The average number of teeth among the subjects was 11.22 and that of dental caries was 1.17. Also, the average number of teeth mobility was 0.93 and halitosis was detected among 81.9%. Only 29.70% reported absence or a kind of systemic disease and 70.31% of the subjects was shown to have more than two kinds of complex disease. In addition, 87.8% of the subjects had depression and among them, 55.40% showed serious depression. The average score on quality of life was 2.62 points and as for the related factors, the number of remaining teeth and dental caries were counted along with care grade, hospitalization period, and age. According to such results, the oral health status among the elderly patients staying long in geriatric hospitals were not good in general; also they showed high level of systemic disease and depression and low quality of life.

  • Maxillary median diastema is the term used when there is spacing between maxillary central incisors. The space between maxillary central incisors are often observed during ugly duckling stage. In most of the cases, as maxillary permanent canines erupt, it gradually disappears. Maxillary median diastema needs to be treated when there is up to 2mm of space between the incisors even after eruption of permanent canines or when there is 3mm of space, at least, before the eruption of the canines. Particulary, for the latter case, orthodontic treatment is recommended because not only the esthetic point of view but also to regain the eruption space for maxillary lateral incisors and canines. The appliance used for orthodontic treatment are removable appliances, using finger spring and etc, and fixed appliances, using rubber elastics and coil spring. If rubber band alone was used to treat median diastema without any other appliance such as band, tube or bracket, it will gradually move downward along the root surface. Then it will destroy the peridontal ligament and causes tooth mobility, extrusion, and avulsion. This report presents cases of damaged tooth due to improper use of rubber band when treating maxillary median diastema.

  • The aim of this study was to investigate the effects of slow maxillary expansion (SME) on the dentoalveolar, skeletal, upper airway, and maxillary sinus using cone-beam computed tomography (CBCT). Twenty-three orthodontic patients (mean age 8.93 ± 1.61 years) who were treated with maxillary expansion using banded hyrax in the Department of Pediatric Dentistry at Jeonbuk National University Dental Hospital were included. According to the expansion speed applied, they were divided into two groups: SME (12 subjects, mean age 8.92 ± 1.45 years) and rapid maxillary expansion (RME, 11 subjects, mean age 8.94 ± 1.84 years). CBCT were obtained before (T0) and after (T1) the treatment and were analyzed with InVivo5 software (Anatomage, San Jose, CA, USA). Descriptive statistics showed no significant differences between the two groups in age, sex, or skeletal maturity. There were significant increases in maxillary width at the dentoalveolar and skeletal levels for both groups. Upper airway volume revealed a significant increase of 38.59% in the SME group and 28.72% in the RME group. However, there was no significant difference between SME group and RME group in all measurements. This study suggested the efficacy of SME in growing patients. SME was effective in increasing not only dentoalveolar and skeletal measurements but also airway volume. Therefore, pediatric dentists should select an appropriate expansion method considering the physiological aspects of periodontal tissues and discomfort in growing children.

  • 스프린트는 치주처지료에서 부가적 처치법으로 널리 사용되고 있으며, 한편, 디지털 공제 활영술은 기존방사선촬영술의 한계점을 극복하기 위해 기발된 새로운 방법이다. 이번 연구에서는 치근활택술 단독시행시와 스피린트 병행 처치시의 효과를 임상적, 방사선학적으로 비교하였다. 중정도의 성인성 치주염을 가진 20명의 환자를 대상으로 하되 10명은 치근활택술 단독으로, 나머지 10명은 스프린트 병행처치로 처치하였다. 임상적, 방사선학적인 평가는 처치전, 처치후 6개월에 행하고, 임상적 평가의 경우 3개월에 추가로 실시하였다. 이번 연구에서 사용된 임상 지수로는 치태지수, 치은지수, 치은퇴축, 치주낭깊이, 임상부착수준, 임상부착증가, 탐침시출혈, 치아동요도 등이며, 방사선학적 평가는 기존 방사선촬영술에 의한 방법과 디지털 공제촬영수렝 의한 방법으로 행하였다. 디지털 공제 촬영술에 의한 평가시, 영상은 Digora 프로그램에 의해 획득하고 Emago 프로그램으로 처리 하여 다음과 같은 결론을 얻었다. 1. 처치후 3개월에 치태지수, 치은지수, 치은퇴축, 치주낭깊이, 임상적부착수준, 탐침시 출혈 등의 임상지수들이 변했으며, 특히 이러한 변화는 치주낭깊이, 치은퇴축, 탐침시출혈에서 유의성이 있었다. ( p<0.05 ) 그러나 두군간 차이는 인정되지 않았다. ( p>0.05 ) 2. 처치후 6개월에도 치태지수, 치은지수, 치은퇴축, 치주낭깊이, 임상적부착수준, 탐침시출혈, 치아동요도 등의 임상지수들이 변했으며, 특히 이러한 변화는 치주낭깊이, 치은퇴축, 탐침시출혈, 치태지수, 치아동요도에서 유의성이 있었다. ( p<0.05 ) 그러나 두 군간 차이는 인정되지 않았다. ( p>0.05 ) 3. 켄달 상관분석시, 임상적 평가와 기존 방사선 촬영술에 의한 평가사이의 관련성을 낮았으며 거의 0에 가까운 수치를 보였으며 (r=0.110, p=0.639 ) 임상적 평가와 디지털 공제 방사선 촬영술에 의한 평가사이에서 약간 높은 관련성을 보였다. ( r=0.257, p=0.315 ) 즉 치주치료후의 골변화는 디지털 공제 방사선 촬영술에 의한 평가시 기존 방사선 사진보다 임상적 부착증가와 더욱 긴밀한 관련성을 보여준다. 이상의 결과로 볼 때, 스프린팅 처치는 치주 치료에 있어 치근활택술에 부가적 표과를 제공하지 못한다.

  • In advanced stages of periodontal disease, a lot of the periodontal tissue support are usually lost. The tissue destruction around some teeth is progressed to a level which requires either spontaneous exfoliation or extraction of several teeth due to their excessive mobility. In such cases, a comprehensive treatment plan encompassing the adequate periodontal and maintenance therapy, as well as perio-prosthetic treatment involving occlusal equilibration, is needed in order to restore health, function, and esthetics. Cross-arch fixed partial dentures(CAFPDs), one of the perio-prosthetic treatments, are used to stabilize the teeth with severely reduced periodontal tissue support. Unfortunately, however, a little is known about the occlusal scheme and biomechanical concept of CAFPDs. This paper will demonstrate summaries of the trauma from occlusion(TFO), Ante's law revisited, the treatment principles, the role of occlusion, and the long-term consequences for CAFPDs, and the possibility of CAFPDs through a case presentation.

  • Purpose: The aim of this study was to evaluate the polymerization ability of resin-based materials used for teeth splinting according to the thickness of cure. Materials and Methods: For this study, the Light-Fix and G-FIX developed for resinous splinting materials and the G-aenial Universal Flo, the high-flowable composite resin available as restorative and splinting material, were used. Ten specimens of the thickness of 2, 3, 4 and 5 mm and 5 mm in diameter for each composite resin (total 120) were prepared. The microhardness of top and bottom surfaces for each specimen was measured by the Vickers hardness testing machine. The polymerization ability of the composite resin for each thickness was statistically analyzed using independent T-test at a 0.05 level of significance. Results: There was no difference of polymerization ability regardless of the thickness in the Light-Fix and G-FIX. The G-aenial Universal Flo showed significantly low polymerization ability from the thickness of the 3 mm (P < 0.05). Conclusion: The Light-Fix and G-FIX, which are resin-based materials used for teeth splinting, are expected to be suitable for light curing up to 5 mm in thickness.

  • Dental sealant is a procedure to prevent dental caries on the occlusal surface of healthy teeth. Raw data from the 6th-7th Korean National Health and Nutritional Examination Survey (KNHANES) were analyzed. This study was conducted to provide basic data which is necessary for the national health care project and for expanding the standards of coverage for the Dental sealant procedure. In this study, subjects were a total of 4,366 children from the age of 6 to 18 and surveyed for the Amount of Received Dental sealant and rate of Received Dental sealant. In 2012, the coverage rate for pit and fissure sealing procedures differed significantly in terms of age, residential area and average monthly income. This coverage varied as per average monthly income in 2014 and as per age and average monthly income in 2017 (P < 0.05). In 2014, average monthly income had a significant influence on the coverage rate, while age and average monthly income had a significant influence on it in 2017 (P < 0.05). These findings suggest that in order to increase the sealing procedure coverage, continuous promotion of dental sealant projects, reduction of copayments, inclusion of varied tooth types and age groups, expansion of coverage to isolated areas and inclusion of socially disadvantaged groups are necessary.

  • Purpose: The purpose of this study was to compare flexural strength and elastic modulus of several splinting materials dependent on water absorption. Materials and Methods: Three different materials; LightFix, G-FIX, G-aenial Universal Flo; were used in this study. Thirty rectangular bar specimens ($25{\times}2{\times}2mm$) of each materials were prepared. Fifteen specimens of each materials were stored in 100% relative humidity atmosphere, $37^{\circ}C$ for 24 hours. The other specimens were stored in distilled water, $37^{\circ}C$ for 30 days. Flexural strength and elastic modulus were calculated using Universal testing machine. One-way ANOVA and Scheffe's post hoc test at 95% level of significance were used on all test results. Results: In LightFix, flexural strength and elastic modulus were significantly decreased after aging. In G-FIX, there was no significant change in flexural strength and elastic modulus after aging. In G-aenial Universal Flo, flexural strength was significantly decreased, but elastic modulus did not change significantly. Statistical analysis reveals that flexural strength and elastic modulus increased in the order of LightFix, G-FIX, G-aenial Flo in both 24 hours and 30 days. Conclusion: It could be deduced from this study that flexural strength and elastic modulus of some resins could be changed when it aged in oral environment. Thus this should be considered when choosing a resin to perform a resin-bonded splint.

  • Burkitt lymphoma (BL) is an aggressive form of non-Hodgkin's B-cell lymphoma found primarily in the pediatric population. In the oral cavity, this tumor can grow rapidly and often brings about facial swelling or development of an exophytic mass involving the jaws. A 5-year-old boy was referred for swelling and pain in the left mandibular area. The patient showed diffuse swelling on the left side of the mandible and firm-moderate tenderness upon palpation. An intraoral examination showed moderate mobility and sensitivity to percussion on the left primary first and second molars, without severe caries. A radiographic examination revealed complete loss of the lamina dura on the left primary second molar and permanent first molar. There was a radiolucent osteolytic lesion and destruction of the cortical bone of the left mandibular body. Based on the clinical, radiographic, and immunohistochemical findings, the patient was diagnosed with BL, and was referred to a pediatrician for systemic evaluation and intensive chemotherapy. Even before the completion of chemotherapy, the swelling resolved and the displaced teeth were relocated to a normal position. This patient showed a good prognosis due to prompt diagnosis and intensive chemotherapy. Early diagnosis and referral for treatment can prevent the development of BL.

  • 다발성 골수증은 다양한 증세를 보이는 형질세포로부터 기원하는 악성종양으로 40세이상의 남성에서 호발되며 alkylating agent 단독, 혹은 corticosteroid와 병용하는 항암제 치료로 생존율이 크게 증가되기는 하였지만 치료후 평균생존기간의 20개월 내외로 완치율이 그다지 높지않은 형편이다. 악골에서의 발생은 극히 드물고 대개 늑골, 편평골, 척추, 골반, 두개골등에 광범위한 patchy destruction의 형태로 나타나는데 악골에 발생할 경우 임상증상은 장기적인 무통성 종창이 가장 흔하며 때로는 동통, 악골의 팽창, 감각이상, 치아의 동요, 악골골절등을 보이기도 한다. 전신적증상으로 무력감, 체중감소, 빈혈, 신부전, hypercalcemia, hyperiviscosity syndrome을 나타내기도 하는데 약 10%의 환자에서 전신적인 amyloidosis를 보인다. 진단은 골수생검상 골수의 plasmacytosis가 10% 이상이면서 혈장이나 뇨전기영동법에서 monoclonal globulin peak이 있을 때 가능하다. 여러 학자들은 처음에는 독립적인 고립성병소로 나타났다가 장기적으로 다발성골수종으로 이행됨을 주장하면서 장기적인 추적을 권하고 있지만 골내 고립성 형질세포종(solitary plasmacytoma in bone), 수질외 형질세포종(extramedullary plasmacytoma) 등은 다발성골수종과는 다른 질환이라 주장하는 등 아직 많은 논란이 있는 형편이다. 치료는 $4000{\sim}6000$ rad의 방사선치료와 여러 가지 약제의 복합적인 항암요법이 사용되고 있으며 국소적인 병소의 경우 외과적 절제술이 추천되기도 한다. 저자들은 59세 여자환자에서 하악골에 발생된 다발성골수종을 치험하였기에 문헌고찰과 함께 보고하는 바이다.
