  • 저한성 외배엽 이형성증은 감모증, 치아의 수 또는 형태이상과 땀샘의 이상이 특징으로 나타나는 질환이다. 이중 치아 이상은 유치열, 영구치열 모두 영향을 받을 수 있으며 완전 무치증, 부분무치증이 특징이며 치아의 형태는 원추형으로 비정상적으로 나타난다. 이에 저자는 완전무치증을 가진 저한성 외배엽 이형성증 경험하였기에 이에 대한 증례보고와 함께 문헌고찰을 하고자 한다.

  • Ectodermal dysplasia is characterized by a partial or complete lack of primary and permanent teeth, other ectodermal structures that may be affected include the skin, hair, and sweat glands. The patient with the so-called anhidrotic type of ectodermal dysplasia exhibits dry skin, lack of sweat glands, sparse eyebrows, body hair, saddle nose, and everted lips. Genetic basis of anhidrotic ectodermal dysplasia is recessive and sex-linked, being manifested chiefly in males, but this is debatable. A 6-year-old boy, with typical signs of anhidrotic ectodermal dysplasia, was presented. Prosthetic restoratoins are of great value to these patients, both from the standpoint of function and for psychologic reasons. The need for complete denture is critical during preschool periods and continues into adulthood. The following case report is an approach to the management of a patient with anhidrotic ectodermal dysplasia.

  • Postsurgical infections are caused by implant-related pathogenic microorganisms that lead to graft rejection. Hence, an intrinsically antibacterial material is required to produce a biocompatible biomaterial with osteogenic properties that could address this major issue. Hence, this current research aims to make strontium-doped hydroxyapatite nanorods (SrHANRs) via an ethylene diamine tetraacetic acid (EDTA)-enable microwave mediated method using Anodontia alba seashells for biomedical applications. This investigation also perceives that EDTA acts as a soft template to accomplish Sr-doping and mesoporous structures in pure hydroxyapatite nanorods (HANRs). The X-ray diffraction (XRD) and transmission electron microscopy (TEM) analysis reveals the crystalline and mesoporous structures, and Brunauer-Emmett-Teller (BET) indicates the surface area of all the samples, including pure HANRs and doped HANRs. In addition, the biocidal ability was tested using various implant-related infectious bacteria pathogens, and it was discovered that Sr-doped HANRs have excellent biocidal properties. Furthermore, toxicity evaluation using zebrafish reports the non-toxic nature of the produced HANRs. Incorporating Sr2+ ions into the HAp lattice would enhance biocompatibility, biocidal activity, and osteoconductive properties. As a result, the biocompatible HANRs materials synthesized with Sr-dopants may be effective in bone regeneration and antibacterial in-built implant applications.

  • A case of dento-maxillofacial abnormality involving a 10-year-old male patient with a history of esthesioneuro-blastoma is presented. This patient had been treated with 54 Gy /sup 60/Co-gamma-radiation to the nasal cavity for 6 weeks and 6 cycles of combination chemotherapy of Cyclophosphamide, Cisplatin, Adriamycin, VM-26 (Tenipo-side), and DTIC (Dacarbazine) when he was 16 months of age. Five years after cessation of cancer therapy, he was disease free and transferred for extensive dental care to Kyung Hee University Dental Hospital. A clinical and radiologic follow-up over last 4 years showed root stunting, premature closure of the root apices, microdontia, developmental arrest, small crowns, and partial anodontia. Maxillofacial morphology evaluated by cephalometric analysis showed deficiency of maxillary development.

  • The authors observed the two cases of Rieger's syndrome in 21-year-old male and 13-year-old female with a chief complaint of Partial anodontia of permanent teeth on both jaws. We had done the laboratory and ophthalmic examinations and had taken radiographs. Final diagnosis was established as Rieger's syndrome. We obtained the results as follows, 1. There was no peculiar hereditary tendency in them. 2. The patients had no disturbance of general physical activity and mentality. 3. The male patient had pseudoprogenathism, concave profile, congenital missing on upper anterior and second premolar teeth, and conical shaped crown of upper len celral incisor. The female patient had also pseudoprognathism, concave profile, thickened upper labial frenum, decreased upper dental arch width, congenital missing on upper anterior teeth, and delayed eruption of second premolars. 4. The ophthalmic symptoms that were ins abnormalities, decreased visual acuity, and increased intraocular pressure were present. 5. The abnormalities except dental and ophthalmic abnormalities were not round.

  • 진단과 치료과정을 통해서 후천적으로 습득된 부정교합을 가진 부분무치악자 성인에게서, 교합고경을 회복해 줌으로써 3급 부정교합 안모에서 정상교합상태의 안모와 기능을 부여할 수 있었다. 대부분의 부분무치악자에서 치조골의 위축, 그리고 감소된 교합고경 인해 이루어진 부정교합자에게서 교합고경의 수복은 매우 어려운 작업이다. 적절한 안모의 심미는 대체로 interlabial gap이 약 0-2mm일 때 얻어진다. 이것과 함께, 제한된 입술 지지도(lip competence)가 교합고경 수복과 적절한 안모의 심미를 위한 지표로 사용될 수 있다. 소개된 증례의 경우는, 7년 이상의 계속 관찰 결과, 성공적인 치료였다고 판단된다. 교합고경을 증가시킨 경우이긴 하지만, 사실은 원래의 정상 교합고경으로 회복 시켜주었다고 하는 것이 더욱 옳은 표현일 것 같다. 교합고경을 증가시키는 작업은 안모의 수복, 절치부의 외상성 교합을 수정하고 하악을 후퇴시키는데 매우 어렵고도 중요한 일이다. 최종적으로, 3급 부정교합이 수정되고, 적절한 교합고경을 가지게 되었으며, 위축된 구치 무치악부가 rigid support 개념으로 제작된 가철성 의치로 수복되었다. 부분 무치악부를 가진 후천적 부정교합자의 치료의 결과로 획득한 치아 및 안모의 심미와 이것의 장기간 안정성은 다음의 관계를 잘 고려함으로써 지속될 수 있을 것으로 사료된다: 1) 이상적인 교합고경에서의 교합수복, 2) 상,하악골 관계에서 기능적으로 유도되는 최종 교합의 허용, 3) lip competence (입술 적응) 한계 내에서 기능적으로 유도되는 최종교합.
