Osteomyelitis in the oral and maxillofacial area is a relatively uncommon inflammatory disease that occurs due to odontogenic causes such as endodontic infection, facial trauma, insufficient blood supply caused by some medical conditions, and iatrogenic postoperative infections. Among them, the incidence rate of candida osteomyelitis in this area is minimal; therefore, no consensus on the diagnosis, treatment, and prognosis has not been established yet. With the increasing number of immunocompromised elderly patients, candida osteomyelitis of the jaw is expected to become more prevalent. In this case report, we present an 81-year-old male patient with candida osteomyelitis of the jaw, including the maxillary and ethmoid sinuses.

The author studied the quality and change of the effective demand for dental treatment of the cutpatients of the Wonkwang dental clinic from the March of 1982 to the August of 1983. The results were compared with the previous reports to find any changes that might come from the effect of dental insurance system. After discussing the results, the author concluded as follows: 1. The twenties were the most in the age groups, but it is desirable that age groups of mixed dentition be the most to enhance the dental health status of community. 2. The effective demand for dental treatment increased especially in the areas such as intraoral radiograph taking, amalgam filling, temporary filling, endodontic treatments, and drug application on the soft tissue, but decreased in the areas such as prosthodontic treatments, and there were no demand for the orthodontic treatment. 3. As compared with the absolute needs, the effective demand was relatively high for teeth extraction and amalgam filling, but it was generally very low. 4. So, the present extent of dental insurance system should be expanded, and the dental care delivery system should be established within the community. Finally, the economic and social status of Iri community should be enhance by political and educational plannings.

Chronic osteomyelitis with proliferative periostitis, known as Garre's osteomyelitis, is a type of osteomyelitis characterized by a distinctive gross thickening of the periosteum of bones. Peripheral reactive bone formation can be caused by mild irritation or infection. Garre's osteomyelitis is usually diagnosed in children and young adults, and the mandible is more affected than the maxilla. The following is a case report of a 12-year-old female patient with Garre's osteomyelitis of the mandible due to an infection of a root canal-treated tooth. Without surgical intervention, the patient's symptoms were relieved through nonsurgical root canal re-treatment with long-term calcium hydroxide placement. A cone-beam computed tomography image obtained 6 months after treatment completion displayed complete healing of the periapical lesion and resolution of the peripheral reactive buccal bone. Due to the clinical features of Garre's osteomyelitis, which is characterized by thickening of the periosteum, it can be mistaken for other diseases such as fibrous dysplasia. It is important to correctly diagnose Garre's osteomyelitis based on its distinctive clinical features to avoid unnecessary surgical intervention, and it can lead to minimally invasive treatment options.

유치에서는 영구치에 비해 법랑질의 두께가 얇고 약하며 상대적으로 큰 치수강으로 인하여 단시간에 치아우식증이 치수까지 이환되며, 외상 또는 치과치료 중 갑작스런 움직임으로 인하여 치수가 노출되는 경우가 빈번하다. 이러한 이유로 어린이에서의 치수처치는 필수적이며, 유치에서 치수치료의 목적은 감염된 치수조직을 제거하여 동통을 완화시키는 것 이외에도 크게는 치열궁을 보존하여 저작기능을 보호하고, 미래의 영구치열이 적절한 교합관계를 이루게 하는데 있다. 유치열에서 성공적인 치수치료를 위해서는 유치 치수의 형태, 유치 근관의 해부학적 형태, 치근형성, 그리고 유치 치근의 흡수와 관련된 특별한 문제점들에 대한 이해를 필요로 한다. 상악 대구치와 마찬가지로 상악 유구치의 근심 치근이 형태에 있어서 가장 큰 변이를 보인다고 알려져 있으며, 이 치근 내에 존재하는 모든 근관을 처치하지 못한다면 결국 치수치료는 실패할 것이다. 본 증례는 근관치료 중이거나 후에 지속적인 동통이나 근관 내 출혈이 지속되는 경우에서 상악 유구치의 근심협측치근의 제 2근심협측근관을 발견하고 처치한 후 임상증상 및 동통이 사라지고, 양호한 예후를 보였다. 또한 발거된 상악 유구치를 대상으로 한 조사 결과 상악 제 1유구치는 35개 증 8개(22.8%), 상악 제 2유구치는 33개 중 22개(66.6%)의 치아에서 제 2근심협측근관이 발견되었으며. 이는 상악 유구치의 근심협측치근 내에 두 개의 근관이 존재할 가능성이 높다는 것을 의미한다.

매복치의 치료방법으로 교정적 견인, 발치 후 임플란트, 자가치아이식 등 다양한 치료 방법이 있다. 그 중에서도 자가치아이식은 성장하는 환자들에게서 이식치 고유의 치주인대세포의 보존 및 치조골 성장이 가능하다는 점에서 좋은 치료방법이라고 생각된다. 이 증례에서는 성장중인 청소년의 이소 매복 치아를 자가치아이식으로 치료한 두 개의 증례를 소개하고자 한다. 첫 번째 증례에서 이소 매복된 좌측 하악 제2소구치를 발거 후 정위치로 자가치아이식하였고 혈소판 농축 피브린(PRF)과 mineral trioxide aggregate (MTA)를 사용하여 재생 근관 치료를 하였다. 석회화 치성낭으로 인해 이소매복된 좌측 하악 제2대구치를 지닌 두 번째 증례에서 병소의 적출술을 시행하였다. Obturator를 3개월 간 장착하여 매복치아의 자발적 맹출을 기대하였으나 맹출 양상이 없어 자가치아이식한 후 MTA를 이용한 근관치료를 하였다. 두 증례 모두 자가치아이식술로 이소매복치를 간단하고 빠르게 치료하였다. 성장하는 환자에게서 이소매복치의 자가치아 이식술은 임플란트나 보철물 수복 대신 좋은 치료 방법이 될 것이다.

외상 치아에서 일반적으로 발생할 수 있는 합병증으로는 치수 충혈, 내출혈, 근관내 석회화 변성, 외흡수, 치수괴사, 유착 등이 있다. 치아의 근관내 석회화 변성은 치아가 외상을 받았을 경우, 발생할 수 있는 이러한 합병증의 하나이다. 석회화 변성은 여러 요소에 의해 확인될 수 있는데 임상적으로는 치관의 황색 계통의 변색과 방사선학적으로는 치수강을 포함한 근관의 부분적 혹은 전체적인 협착을 특징으로 한다. 이러한 석회화 변성이 발생할 경우, 치수 괴사로 이행되기도 하는데, 모두 치수 괴사로 이행되는 것은 아니며 따라서 근관 치료에 앞서 적절한 검사 및 관찰이 필요하다. 본 증례는 만 9세의 여아가 놀던 중 친구의 머리에 부딪혀 상악 중절치의 외상(subluxation)을 받고 내원한 경우로 지속적인 임상적, 방사선학적 검사를 시행한 결과 근관내 석회화 변성이 관찰되었다 검사 초기에는 임상적으로 경미한 치관의 변색만 보였을 뿐, 전기 치수 검사(EPT)에서는 특이한 소견은 보이지 않았다. 그 후 전기 치수 검사를 이용한 지속적인 검사 결과, 그 반응의 정도가 점차 감소되었으나, 근관 치료는 좀 더 유보하고 관찰하기로 하였다 외상 후 20개월 정도 지나서는 전기 치수검사를 이용한 검사에 거의 반응을 보이지 않았고, 근관의 완전 협착과 치관의 황색 계통의 변색이 관찰되었다. 이에 치수 괴사로 이행되는 것을 막고 치관의 변색술을 시행하기 위하여 근관 치료를 시행하고 그 결과를 보고하는 바이다.

Background: The objective of the present study was to examine the status of patients who had received dental treatment under intravenous (IV) sedation at Chungnam Dental Clinic for the Disabled in Korea from its inception to the present time, and to review the analysis results. Methods: Retrospective analysis was performed on 305 cases of patients who had received dental treatments under IV sedation between January 2011 and May 2016. The analysis examined the patient's sex, age, primary reason for IV sedation, duration of anesthesia and dental treatment, type of dental treatment performed, number of clinical departments involved in the dental treatment and level of multidisciplinary cooperation, and annual trends. Results: Most dental treatments using intravenous sedation were performed on medically disabled patients or dentally disabled patients with an extreme gag reflex or dental phobia. The mean duration of IV sedation was 72.5 min, while the mean duration of treatment was 58.0 min. The types of dental treatments included surgical treatment (n = 209), periodontal treatment (n = 28), prosthodontic treatment (n = 28), restorative treatment (n = 23), implant surgery (n = 22), endodontic treatment (n = 9), reduction of temporomandibular joint dislocation (n = 1), and treatment of traumatic injuries (n = 1), with treatments mostly performed on adult patients. Conclusions: With increasing demand for minimally painful treatment, cases using IV sedation are on an upward trend and are expected to continue to increase.

Most of disabled people face hardness in caring their general oral hygiene by themselves. So that, they are once involved in dental caries or periodontal disease, they have much bigger chance of aggressive progress. Therefore preventive dentistry is more important to disabled one than non-disabled. They need to be checked with routine periodic dental examination and by that, oral disease must be found at initial stage. We selected 37 patients from newly visited 237 patients who had dental treatment at the free dental clinic, Gangnam district, Seoul, between 2000 and 2001. This study is a comparative evaluation of first 2 years' treatment records of selected 37 patients (male 28, female 9) with that of their last 2 years. 24 of 37 have mental retardation, 9 have autistic disorder, 2 have auditory disorder, 1 has brain disorder and 1 has crippled disorder. Their dental treatment records categorized by 4 level; score 4 stands for endodontic treatment, score 3 stands for general conservative treatment, score 2 stands for preventive treatment, such as sealant and score 1 stands for routine check. In first 2 years of treatment, average score was 2.85 which score means approximately general conservative treatment. And that of last 2 years was 1.44, which means routine check. In early time of their visit, they will receive the treatment due to their chief complaint. And after that early time, they can have a routine check so that they can be treated before the disease get worse. The patient's oral health can remain decent only by a simple treatment.

Purposes: This study employed a posteriori registration and subtraction of radiographic images to quantify the apical root resorption in maxillary permanent central incisors after orthodontic treatment, and assessed whether the external apical root resorption (EARR) was related to a range of parameters involved in the treatment. Materials and Methods: A sample of 79 patients (mean age, $13.5{\pm}2.2years$) with no history of trauma or endodontic treatment of the maxillary permanent central incisors was selected. Periapical radiographs taken before and after orthodontic treatment were digitized and imported to the Regeemy software. Based on an analysis of the post-treatment radiographs, the length of the incisors was measured using Image J software. The mean EARR was described in pixels and relative root resorption (%). The patient's age and gender, tooth extraction, use of elastics, and treatment duration were evaluated to identify possible correlations with EARR. Results: The mean EARR observed was $15.44{\pm}12.1pixels$ (5.1% resorption). No differences in the mean EARR were observed according to patient characteristics (gender, age) or treatment parameters (use of elastics, treatment duration). The only parameter that influenced the mean EARR of a patient was the need for tooth extraction. Conclusion: A posteriori registration and subtraction of periapical radiographs was a suitable method to quantify EARR after orthodontic treatment, and the need for tooth extraction increased the extent of root resorption after orthodontic treatment.
