Early childhood caries is a widespread condition that requires attention; however, its treatment remains a challenge in terms of child behavior management. This study describes the usefulness of customized zirconia crowns for the restoration of deciduous teeth through the evaluation of some cases. Three cases are described: a 29-month-old girl who presented with severe early childhood caries affecting anterior tooth, a 50-month-old boy who presented with extensive caries of his anterior tooth, and 70-month-old girl who presented with extensive caries of his primary posterior dentition. These prefabricated, zirconium-based ceramic crowns ($Nusmile^{TM}$ NuSmile) are available in various sizes, shapes and colors. Before the treatment, radiographs and intraoral photographs were taken to evaluate the appropriateness of treatment. Our findings indicate that customized zirconia crowns may be appropriate for restoring the deciduous teeth. Further long-term clinical studies are required to clarify the usefulness of this restorative method.

소아 및 청소년에서 유구치 및 대구치는 인접면이나 평활면에 광범위한 치아우식증으로 치질이 많이 파괴되거나, 치수치료로 인하여 치질 부위가 약해져서 파절되기 쉬운데, 치료방법으로 기성금속관이 사용되고 있다. 기성금속관은 1950년대 Humphrey에 의해서 소개되었고, 장점으로 내구성이 강하고, 임상적 수명이 길며, 성공률이 높지만, 치질 삭제로 인한 치수노출 위험성과 인접 치아의 삭제의 가능성이 있고, 다수의 치아 수복 시에 교합면 높이를 맞추기 어려우며, 큰 크기의 기성금속관을 선택한 경우 금속관의 변연에 의해 인접 치아의 맹출을 방해할 수 있다는 단점이 있다. 기성금속관의 단점을 보완하기 위한 방법으로 구치부 수복 시 교정용 밴드를 사용하는 것을 고려해 볼 수 있는데, 치아우식증으로 파괴된 치질 부위를 교정용 밴드와 복합레진, 또는 글래스아이오노머, 아말감 등으로 수복하는 방법이다. 교정용 밴드를 이용한 구치부 수복은 치경부와 교합면에 치아우식증이 있어 치질이 많이 파괴되거나, 치수치료한 치아, 법랑질 저형성된 대구치 등에서 사용될 수 있고, 시술 시간이 짧아 행동조절이 어려운 어린이에서 유용하다. 그러나, 치료 후 구강위생상태를 청결히 유지시키는 것이 중요하다. 이 증례들에서는 유구치와 대구치에 광범위한 치아우식증의 치료를 위해 내원한 환아에서 교정용 밴드를 이용한 보존적 수복치료를 시행하여 양호한 결과를 보여 이를 보고하는 바이다.

Early childhood caries is a global healthcare concern in developing and industrialized countries. If left untreated, it leads to immediate and long-term complications that affect the well-being and quality of life of concerned families. Therefore, many preventive and treatment approaches are available to the healthcare provider to curb this virulent form of caries. After behavioral interventions, general anesthesia is used in specific settings when a young patient presents with extensive teeth damage and exhibits a lack of cooperation that is incompatible with conventional dental office care. However, without proper follow-up, any positive results might be lost over time.

Objectives: Dental caries is one of the most prevalent human diseases worldwide. The disease initiates with bacterial adherence to the tooth surface followed by the formation of dental plaques. Mutans streptococci and Candida albicans are principal oral microorganisms involved in the initiation and development of dental caries. Phytochemicals have been shown to possess promising antimicrobial properties against a wide range of microorganisms and can be used for the prevention and treatment of dental caries. Herein, we reviewed literature on plants that are traditionally used for their antimicrobial properties or possess promising anticariogenic activity. We selected aerial parts of Scrophularia striata (S. striata) and galls of Quercus infectoria (Q. infectoria) and investigated their antimicrobial activity against cariogenic microorganisms. Methods: Water soluble fractions were obtained from hydroalcoholic extracts of S. striata and Q. infectoria and their antimicrobial activity against Streptococcus mutans (S. mutans), Streptococcus sobrinus (S. sobrinus), and Candida albicans (C. albicans) was evaluated separately and in combination. The extracts were then used for preparing an herbal mouthwash whose stability and tannic acid content were evaluated over 60 days. Results: Q. infectoria gall extract possesses efficient antimicrobial activity that was synergistically enhanced in the presence of S. striata extract. Mouthwash prepared using these extracts showed desirable organoleptic characteristics, antimicrobial activity, and stability. Conclusion: Extracts of S. striata and Q. infectoria galls can be used together for preparing dental products with effective anticariogenic properties. Our study highlights the importance of extensive pharmacological investigations when using herbal products alone or in combination with other chemical substances.

Williams syndrome is a rare congenital disorder with various physical abnormalities and characterized by facial, oral, and dental features. Individuals with Williams syndrome typically have eating disorders in the early childhood, which lead to prolonged night feeding. Prolonged night feeding is a risk factor for rampant dental caries. Williams syndrome is caused by the microdeletion of chromosome 7, resulting in elastin deficiency. Elastin is integral to cardiovascular health. Many patients with Williams syndrome have complex cardiovascular abnormalities that must be considered a part of dental management. Complications related to cardiovascular diseases may induce adverse effects such as dangerously elevated blood pressure. This may occur in patients during stressful dental treatment. In addition, characteristics of auditory hyperalgesia and anxiety disorders among patients with William syndrome, complicate receiving routine dental management. Therefore, dental treatment under sedation or general anesthesia may be preferable for patients with Williams syndrome; in particular, patients who are very uncooperative and/or needs extensive dental treatment. A thorough evaluation of each patient's physical condition is required before making decisions regarding dental treatment. Careful monitoring and preparation for emergencies are very important during and shortly after dental treatment under general anesthesia or sedation. Monitoring is critical until vital signs have stabilized and return to normal. A 28-month-old man diagnosed as having Williams syndrome, visited the Dental Hospital of ${\bigcirc}{\bigcirc}$ University for the management of rampant dental caries. We reported on the management of this patient who had peripheral pulmonic stenosis, and received dental treatment under general anesthesia. We also reviewed the characteristics of Williams syndrome and discussed considerations for dental treatment under general anesthesia.

Although periapical inflammatory lesions are usually resulted by infection in the root canal system, this rare case showed that a periapical lesion related to an infected tooth may cause pulpal necrosis in adjacent intact tooth, with no history or clinical signs of caries, disease, trauma or developmental anomaly. This case also suggests that the periapical lesion can be treated conservatively, without surgical intervention. Furthermore, this case highlights the importance of prompt treatment of apical periodontitis before the lesion becomes extensive as well as follows up of large lesions.

Hidden caries는 임상 검사상 교합면이 매우 건전하거나 소량의 탈회만이 관찰되지만 방사선 사진 상에서 상당 수준 진행된 상아질 우식이 발견되는 경우를 일컬으며 Covert caries, Occult caries, Fluoride syndrome 등이 동의어로 사용되고 있다. 발생 원인으로는 불소의 영향, 세균의 종류 및 세균 영양분 공급 경로의 차이, 열구 기저면으로부터 시작된 우식증, 맹출 전우식증 등의 주장들이 제기되고 있지만 현재 정확한 원인은 밝혀지고 있지 않다. 본 증례는 임상 및 방사선 사진 검사에서 Hidden caries를 발견한 두 환아들의 치험례로 두 증례 모두에서 깊은 상아질 우식을 보여 각각 치근단 형성술과 간접치수복조술을 시행하였다. 교합면이 비교적 건전해 보이는 특징 뿐만 아니라 Hidden caries의 우식 상아질은 임상적으로 관찰 가능한 우식에서 채취한 우식 상아질에 비해 밝은 색을 띄는 특징이 있어 시진으로 관찰하기 더욱 어려운 것으로 생각된다. 따라서 본 증례와 같이 진행된 우식병소로 인해 임상증상이 발현된 후에야 이를 발견하게 되는 경우가 많으므로 정기적인 방사선 검사와 함께 Diagnodent.. 등과 같은 최신의 우식 진단도구들의 사용으로 우식병소의 조기진단을 위해 노력해야 할 것으로 생각된다.

Wolff-Hirschorn syndrome is a condition that is caused by a deletion of genetic material near the end of the short (p) arm of chromosome 4. The major features of this disorder include a characteristic facial appearance, delayed growth and development, intellectual disability, and seizures. A 9-year-old girl was brought to the clinic with a chief complaint of dental examination. The child was diagnosed as WHS at Samsung medical center. The child was under Sodium valproate, Atrovastatin medication for epilepsy, hyperlipidemia and had a history of heart surgery. So prophylactic antibiotics were recommended. The child was mentally retarded and had seizure so it was difficult to manage her behavior effectively. Thus dental treatment was carried out under general anesthesia. For prompt sedation induction we used 8% sevoflurane shortly. This report presents the case of a 9-year-old girl with WHS, who has received treatment for extensive caries under general anesthesia.
