Orthodontic treatment of a complex case that involves retained deciduous mandibular second molars with missing permanent successors is challenging. Usually, congenitally missing teeth are manifested with other dental anomalies that further complicate orthodontic treatment, such as retained deciduous teeth, impactions, transpositions and peg-shaped lateral incisors. Even though the long term prognosis of the retained deciduous tooth is not fully predictable, if the teeth are in good condition, the patient and clinician may incline towards a decision to preserve the deciduous teeth as long as possible. This case report demonstrates that deciduous teeth, in this case the mandibular second molars and maxillary canine, can be incorporated into final occlusion with clinically stable long-term results.

Tooth related factors such as palatoradicular groove can be one of the causes for localized periodontal destruction. Such pathological process may result in apicomarginal defect along with inflammation of pulp. This creates challenging situation which clinician must be capable of performing advanced periodontal regenerative procedures for the successful management. This case report discusses clinical management of apicomarginal defect associated with extensive periradicular destruction in a maxillary lateral incisor, along with histopathologic aspect of the lesion.

Odontogenic anomalies can occur as a result of conjoining defects. These include fusion, gemination and concrescence. The presence of fused teeth can lead to various clinical problems, including the aplasia of permanent successor, the supernumerary teeth and delayed eruption of permanent teeth. In general, the supernumerary teeth associated with fusion is mainly found in the maxillary anterior region. This report describes rare cases of supernumerary tooth associated with fused teeth of mandibular primary lateral incisor and canine. In the first case, fused teeth was extracted. The supernumerary teeth was erupted at canine space. The second case is still being observed. Extraction of fused teeth and observation of supernumerary teeth is planned.

윌리엄스 증후군은 심혈관계, 결합조직 및 중추신경계에 다발성 이상이 발생되는 선천성 장애이며 정신지체, 특이한 안모, 심혈관 질환이 동반되고 치아의 형태 이상, 치아 결손, 부정교합 등의 전형적인 구강내 소견을 나타낸다. 본 증례에서는 윌리엄스 증후군으로 진단된 환자에서 이미 보고된 구강내 소견 외에 영구치의 비정상적 맹출 경로로 인한 매복 소견이 나타났으며 이에 대한 치과적인 치료 과정을 보고하는 바이다.

Fusion and gemination are developmental anomalies of teeth that may require endodontic treatment. Fusion may cause various clinical problems related to esthetics, tooth spacing, and other periodontal complications. Additional diagnostic tools are required for the diagnosis and the treatment planning of fused tooth. The present case report describes a case of unilateral fusion of a supernumerary root to an upper permanent central incisor with large periapical lesion in which a conservative approach was used without extraction of supernumerary tooth and obturated with mineral trioxide aggregate to reach a favorable outcome.

Patients with pediatric cancer often undergo multiple therapies, such as chemotherapy, radiation therapy, and stem cell transplantation. These treatments, while essential, can result in dental developmental issues, including hypodontia, microdontia, short roots, and delayed dental development. This report presents two cases of pediatric patients diagnosed with neuroblastoma who exhibited severe tooth mobility due to short roots as a complication of cancer treatment. Moreover, we investigated the conservative management of the patients' conditions using resin wire splints and orthodontic miniscrews for skeletal anchorage along with long-term follow-ups to evaluate their prognosis.

저자는 Axenfeld-Rieger 증후군을 가지는 5세 8개월 연환에 대한 구강 및 두개 안면에 대한 임상적, 방사선학적 관찰을 통해 다음과 같은 지견을 얻었다. 1. 본 증례의 환아는 Axenfeld-Rieger 증후군의 전형적인 안과적, 구강적, 전신적 특징인 녹내장, 동공이상, 제탈장, 지연된 골령, 다수 치아 및 치배 결손, 상악 저성장 등을 보였다. 2. 이에 대한 주기적인 관찰과 적절한 시기의 치료개입이 중요하다. 3. 치과의사에 의한 조기진단이 녹내장 등에 의한 시력상실을 방지하기 위해 중요하다.

이 연구는 2016년 11월부터 2017년 10월까지 서울대학교 치과병원 소아치과에 내원한 5세부터 13세 사이의 3984명 환자의 파노라마 방사선 사진을 조사하여, 측절치 발육 이상과 맹출 장애의 빈도 및 연관성에 대해 분석하였다. 측절치 발육 이상의 유병률은 10.0%였으며, 선천적 결손(66.1%), peg-shape 측절치(33.5%) 순으로 높은 빈도를 보였다. 영구치 맹출 장애의 유병률은 15.9%였으며, 상악 견치(29.7%)에서 가장 호발하였고, 상악 중절치(24.7%)에서도 높은 빈도를 보였다. 측절치 발육 이상이 관찰된 환자 중 30.8%에서 맹출 장애가 관찰되었는데, peg-shape 측절치(p < 0.001), 발육 저하된 측절치(p < 0.001) 그리고 치내치(p = 0.004)의 존재가 맹출 장애 발생과 유의한 상관 관계를 보였다. Peg-shape 측절치와 치내치가 관찰된 환자는 상악 견치의 맹출 장애가 높은 빈도를 보였고, 발육 저하된 측절치를 가진 환자는 상악 중절치의 맹출 장애가 가장 많이 관찰되었다. 측절치 발육 이상이 관찰되는 환자는 정기적인 검진을 통해 맹출 장애를 조기에 발견하는 것이 중요하며, 측절치 발육 이상과 맹출 장애 간의 연관성을 염두에 두고 최적의 시기에 적합한 진단과 치료계획을 세우는 것이 중요하다.

Steatocystoma multiplex is an uncommon benign skin disease, which typically manifests as numerous intradermal cysts that can be scattered anywhere on the body. Although usually asymptomatic, it can be significantly disfiguring. One type of steatocystoma multiplex is known to be associated with the autosomal dominant inheritance of a mutation in the gene coding for keratin 17 (KRT17). In such cases, it is often concurrent with other developmental abnormalities of the ectoderm-derived tissues, such as the nails, hair, and teeth. To the best of our knowledge, few cases have been reported of steatocystoma multiplex of the oral and maxillofacial region. This report describes a case of steatocystoma multiplex of both sides of the neck and multiple dental anomalies, with a focus on its clinical, radiological, and histopathological characteristics, as well as the possibility that the patient exhibited the familial type of this condition.
