Completely avulsed tooth caused by a traumatic injury needs replantation for treatment choice. But, replantated tooth usually comes with inflammatory root resorption, replacement resorption and ankylosis, moreover ankylosis cause severe functional and esthetic problems. The outcome of replantated tooth depends on the following factors; minimal damage to pulp and periodontal tissue, the length of extraoral time, the medium of the tooth stored, the level of root formation and so on. The purpose of this case report is to describe the variable resorption pattern and to discuss types that influence the occurrence of resorption.

목적: 본 연구의 목적은 두 종의 라미네이트 세라믹 비니어의 글레이징 여부에 따른 반투명도 변화를 비교하는데 있다. 재료 및 방법: IPS e.maxPress (IEM)와 Styleveneers (STV)를 대상으로 하여 각각 0.3 mm와 0.6 mm 두께의 한 변이 10 mm인 정사각형 형태의 시편을 글레이징을 시행한 군과 하지 않은 군으로 나누어 제작하였다(n=80). 각 시편은 측색기를 이용하여 색좌표(CIE $L^*a^*b^*$)를 측정하였다. Translucency Parameter (TP)는 측정한 색차를 계산하여 얻었다. 각 제조사별 차이와, 글레이징 여부에 관한 통계 분석을 위해 독립표본 t-test를 시행하였다(P=.05). 결과: IEM의 0.3 mm 두께에서 TP값(평균${\pm}$표준편차)은 글레이징을 시행하지 않은 군에서 $45.99{\pm}3.00$, 글레이징을 시행한 군에서 $49.53{\pm}2.28$이었으며, 0.6 mm 두께에서는 각각 $32.82{\pm}2.59$과 $43.02{\pm}0.98$이었다. 마찬가지로, STV의 0.3 mm 두께에서 TP값은 글레이징을 시행하지 않은 군에서 $47.03{\pm}3.65$, 글레이징을 시행한 군에서 $50.95{\pm}3.05$이었으며, 0.6 mm 두께에서는 각각 $34.48{\pm}1.28$과 $43.39{\pm}1.20$이었다. 세라믹 비니어의 글레이징 여부에 따라, 세라믹 비니어의 TP값은 통계적으로 차이가 나타났다. 그러나 제조사간의 통계적 유의성은 없었다. 결론: 한계는 있지만, 본 연구에서, 라미네이트 세라믹 비니어는 글레이징 과정을 거치면 반투명도가 변화되며, 제조사간의 차이는 없다는 결론을 얻었다. Purpose: The aim of this study was to compare the translucency of two different laminate ceramic veneers with and without glazing. Materials and methods: Ten millimeter side square-shaped specimens in 0.3 mm and 0.6 mm thick were fabricated for the following materials with and without glazing (n=80): A1 shade IPS e.maxPress (IEM) and Styleveneers (STV). The color coordinates (CIE $L^*a^*b^*$) of the specimens were measured with a colorimeter. The Translucency parameter (TP) was calculated from the color difference of the material on a black versus a white background. For comparisons between materials and between the 'not glazed' and 'glazed' groups, unpaired t-test was used to analyze the data (P=.05). Results: The TP ($Mean{\pm}SD$) of 'not-glazed' and 'glazed' group of IEM specimens at 0.3 mm thickness were $45.99{\pm}3.00$ and $49.53{\pm}2.28$ and the TP at 0.6 mm thickness were $32.82{\pm}2.59$ and $43.02{\pm}0.98$, respectively. Likewise, the TP of 'not-glazed' and 'glazed' group of STV specimens at 0.3 mm thickness were $47.03{\pm}3.65$ and $50.95{\pm}3.05$ and the TP at 0.6 mm thickness group were $34.48{\pm}1.28$ and $43.39{\pm}1.20$, respectively. As the glazing of ceramic veneer differed, the TP of each ceramic veneer showed statistically significant difference. But, the result between the products was not statistically different. Conclusion: Within the limitations of this study, we are concluded that the glazing process changed translucency of laminate ceramic veneers and the TP would not be affected by products.

오진된 치성 피부 누공의 진단과 치료

김성준(Sung-Joon Kim),감세훈(Se-Hoon Kahm) 대한치과의사협회 2014 대한치과의사협회지 Vol.52 No.6

The cutaneous sinus tract is an uncommon disease. It is difficult to diagnose exactly of odontogenic cutaneous sinus tract for dentists or dermatologists except experienced clinicians or previously known clinicians. Many patients may be treated with repeated surgical excisions, biopsies, and antibiotic medications, but most of them could be frustrated with the recurrence of disease. There are several methods for diagnosis of odontogenic cutaneous sinus tract such as GP cone tracing, conventional computed tomography(CT), periapical x ray imaging, and cone beam computed tomography(CBCT). This case report describes the diagnosis and treatment of odontogenic cutaneous sinus tract that referred from medical doctors.

The odontogenic cutaneous fistula in facial area is uncommon but, well defined disease. It is difficult to diagnose from the dental origin of cutaneous sinus tract. Most patients may visit to the dermatologists or general hospital without cause of disease. They usually be treated by repeated surgical excisions, biopsies, and antibiotic medications, but suffered from recurrences. We studied odontogenic cutaneous fistula through retrospective study in Jeju Special Self-Governing Province between 1 January 2009 and 12 December 2015. There were 3 males, 5 females from 14 to 78 years old with an average age of 50.4 years old. Only 2 patients felt the toothache, others didn’t detect it. They suffered from recurrences and repeated treatments for 3 to 11 months with an average period of 7.9 months. They visited average 2.8 hospitals before a precise diagnosis in a dental clinic. All cases were fully healed endodontic treatment or extraction of origin teeth without recurrences. In conclusion, the cause of cutaneous fistula in facial area can be odontogenic. If dentists or doctors diagnose a patient with cutaneous fistula on face, they should check dental problems or take x-ray views for precise diagnosis. It could be helpful for differential diagnosis.

Objectives: The objective of this work was to investigate the hospital nursing care of oral and maxillofacial health in jeju province. Methods: 438 Registered nurses(RN) who were working at each of secondary hospitals in Jeju province had responded to the questionnaire. The data were analyzed via frequency analyses and one way ANOVA to assess the state of RN on hospital nursing care of oral and maxillofacial health. Results: The class of education on density in formal density that marked ‘0 hour’ and ‘1 3 hours’ were 73.5% and 19.9%, respectively. The class of refresher training on density that marked ‘0 hours’ and ‘1 3 hours’ were 92.9% and 6.6%, aggregately 99.5%. The nursing education on appearance after tumor of maxillofacial area that marked ‘formal education’ and ‘none’ were 45.2% and 52.1%, respectively. The score of question ‘function, effect and side effect of hexamedin gaggle’ was 2.68±0.95 by Likert 5 point scale. Likewise, the scores were 2.82±0.88 on question ‘management of removal denture’, 2.83±0.95 on question ‘preventive dental treatment before anticancer therapy’, 2.88±0.86 on question ‘function of saliva’, 2.96±0.99 on question ‘oral management of tube feeding patient’, 3.13±1.00 on question ‘bacterial endocarditis from oral microflora’, 3.36±0.89 on question ‘dysphagia’ and 3.62±1.03 on question ‘aspiration pneumonia’. RN replied that ‘lack of knowledge’ and ‘delay of cooperation’ formed 53.7% and 33.3% respectively, on question ‘problem in dental consultation other diseased patient’. Conclusions: From this study, it is necessary for RN and student of nursing science to be educated on the oral and maxillofacial nursing. Authors suggest further co study and nation wide research.

제주 지역 간호사의 구강 악안면 영역 손상에 대한 응급 처치 인식도

The purposes of this work were to assess the cognition of the registered nurse(RN) on oral and maxillofacial emergency treatment and to compare cognition of the RN with that of the 119 emergency medical technician(EMT). 450 RNs who were working at each of secondary hospitals in Jeju province had responded to the questionnaire. Independent sample t-test and chi-square test were used to assess the state of RN on dental emergency treatment and to compare RN with EMT. The question "education time on dentistry in formal education" that marked "0 hour" and "1-3 hours" were 73.3% and 20.0%, respectively. The question "refresher training class on dentistry" that marked "0 hour" and "1-3 hours" were 92.9% and 6.7%, aggregately 99.6%. The results showed low score in the question "reduction of temporo-mandibular joint(TMJ)"(1.67±0.857), "fixation of dislocated TMJ"(1.70±0.853) and "post-avulsed tooth treatment"(1.78±0.774) by 5-point Likert scale. Likewise, the scores were 2.02±0.806 in the question "treatment of maxillofacial trauma", 2.76±1.061 in the question "emergent care of avulsed tooth", 2.70±1.095 in the question "treatment time of avulsed tooth" and 2.79±1.056 in the question "mouth guard", respectively. Compared to EMT, results of RN showed a statistically lower figure(ph0.05) in all items compared except the question "medicine control", and the question "doctor care in emergency room" was borderline(p=0.069). From this study, it is necessary for RN and student of nursing science to be educated on the oral and maxillofacial emergency treatment for the initial management of injuries. Authors suggest further co-study and nation-wide research with nursing care.
