The purpose of this study was to assess the thickness of unpolymerized layers on sealants and to estimate the degree of polymerization of sealants. In this study, amterials used were four kinds of visible light-cured sealants and two kinds of chemically cured sealants. The thickness of unpolymerized layer was assessed by light microscope and the degree of polymerization was analysed by FTIR spectroscopy and following results were obtained. 1. The thickness of unpolymerized layers ranged from 6.33 to 13.89㎛ in light cured sealants and from 67.11 to 75.00㎛ in chemically cured sealants, and the thickness of unpolymerized layer of light cured sealants were thinner than those of chemically cured sealants(p<0.001). 2. As the exposure time incureased, the differences of thickness of unpolymerized layers in light cured sealants were statistically insignificant except differences between 10 seconds group and 20 seconds group of Concise(p<0.01). 3. As the exposure time increased, the increases of degree of polymerization between 10 seconds group and 20 seconds group of Pit & Fissure Sealant and Teethmate-A were statistically significant (p<0.01). 4. The detree of polymerization of Teethmate-A, Fissureseal and Hi-Pol was greater than that of other visible light cured sealants(p<0.01).

Frankel appliance(FR-2)를 이용한 2급 부정교합 환자의 치험례

이긍호,최영철,부성언 大韓小兒齒科學會 1990 大韓小兒齒科學會誌 Vol.17 No.2

The functional regular(FR-2) is a removable orthodontic appliance developed by Rolf Frankel that is used during the mixed and early permanent dentition stages to effect changes in anteroposterior, transverse, and vertical jaw relationship in class Ⅱ malocclusions. This appliance serves as a template against which the craniofacial muscles function. The framework of the appliance provides an artificial balancing of the environment, thereby promoting more normal patterns of muscle activity. The Frankel also influences skeletal and dental development. The appliance removes muscle forces in the labial and buccal areas that restrict skeletal growth, thereby providing an environment that maximizes mandibular growth. The case presented here and the progressive analysis reveals the forward and downward growth of the mandible remarkably. This patient with severe overjet, convex profile, underdeveloped and retrognathic mandible have been treated with FR-2, and forward and downward growth of the mandible was observed.

The use of general anesthesia as a special method of behavior management is necessary if certain handicapped or very young patients are to receive dental treatment. This study was designed to report the results of 29 cases of complete oral rehabilitation under general anesthesia. The data were obtained from 29 patients managed at the Dept. of Pedodontics, Kyung Hee Medical Center. The distribution of age, sources of referral, primary reason for general anesthesia, preperative physical status, oral condition, intubation methods, drugs used for maintaining the general anesthesia, types and extent of dental treatment, duration of procedure, duration of hospitalization, and postoperative complications were surveyed. The results were obtained as follows: 1. In distribution of age, most(82.7%) were younger than 10 years and mean was 8.6 years(range 2-25). The major source of referral of patients were local or other hospital dentists(69.0%) and the others(31.0%) came to the practice at their own initiative. 2. In the primary reason for general anesthesia, the majority of the patients (82.8%) were mentally or physically handicapped and others(17.2%) were received general anesthesia because of management problem. 3. In the preoperative physical status, the majority of the patients(97%) were in ASA class Ⅰ or classⅡ. In the preoperative oral condition, only the caries teeth were surveyed, the mean number of caries teeth was 11.1(range 3-20). 4. Nasotracheal intulbation was used in 23 patients(79.3%) and the drugs used for maintaining the general anesthesia were Halothane(82.8%) and Ethrane(17.2%). 5. In the performed dental treatment, the mean number of teeth treated with amalgam or composite resin was 7.0(range 1-13), vital pulpotomy was 1.7(range 0-7), stainless steel crown was 0.9(range 0-5), and the number of extracted teeth was 2.6(range 0-10). The mean duration of procedure was 129 minutes(range 65-230), and the mean duration of hospitalization was 1.9 days (range 1.0-2.0) 6. Of the patients, postoperative complications developed in 12 patients (41.5%). The most frequent complication was postoperative fever(n=8), followed by swelling of the lip and/or cheek, vomiting, and upper respiratory infection.

아동의 하악골에 발생한 복합 치아종의 외과적 처치에 관한 증례보고

이긍호,최영철,정우성 大韓小兒齒科學會 1999 大韓小兒齒科學會誌 Vol.26 No.3

악골에서 비교적 흔한 빈도로 발생하는 치아종은 치배조직의 과성장으로 인하여 발생한다.세계보건기구에서는 치아종을 복잡 치아종과 복합 치아종으로 구분하고 있다.치아종은 악골내 모든 부위에서 발생할 수 있지만 치아와 유사한 복합 치아종은 비교적 상악 전치부에 호발하고,불규칙한 형태를 나타내는 복잡 치아종은 하악 구치부에 호발한다.치아종의 원인은 정확히 알려져 있지 않으며 치배에 대한 구소적인 외상이나 감염이 주된 요인으로 추측되고 있고,최근에는 유전적인 원인에 대해서도 연구되고 있으나 아직 확실히 입증되지는 않고 있다.일반적인 증상이 없기 때문에 일상적인 방사선 검사에서 주로 발견되고 영구치의 맹출지연이나 유치의 만기잔존 등이 증상이 있을 수 있다.치아종은 구강내의 어떤 부위에서도 발생이 가능하고 드물기는 하지만 상악동,하악의 하연,하악지 및 하악과두 하방에서 발견되기도 하며,이공 부위에서 발생되는 경우도 있다. 치아종은 발육중인 치열과 악궁에 미치는 영향을 최소화하기 위하여 발견되는 즉시 낭포 및 주위 연조직을 함께 외과적으로 제거하는 것이 바람직하다.환자의 연령과 치과치료에 대한 협조도,영구치열의 발육상태,치아종의 악골내 위치 및 동시적인 치과치료가 요구되는 가를 고려하여 외래 진료실에서 하는 경우도 있고 전신마취를 통하여 하는 경우도 있다. 본 증례는 치아종의 악골내 위치가 깊지 않고 치과치료에 대한 협조도가 양호하다고 판단되는 환아에서는 외래 진료실에서 국소마취하에 수술하여 치료하였고,연령이 어리고 치아종이 악골내 위치가 깊어 장시간의 시술 시간이 요구되고 동시에 보존적인 치과치료가 필요한 환아에서는 전신마취하에 치료한 것을 보고한 것이다.두 증례에서 수술 4개월 후 외과적 결손 부위에 골이 형성되었고,매복된 영구치의 맹출이 정상적으로 이루어진 것으로 나타났다. The Odontogenic is relatively a common benign odontogenic tumor and caused by overgrowth of odontogenic tissues.The recent classification by World Health Organization divides odontoma into 2 groups such as compound odontoma and complex odontoma.Compound odontoma comprises dental tissues,resembling the morphology of a tooth and has predilection for the anterior maxilla.In contrast,complex odontoma has unorganized mass,not resembling the normal tooth and has predilection for the posterior mandible.The etiology of odontoma is unknown and almost asymptomatic.So,it usually is found in routine radiographic examination,and most common presenting symptom is impacted or unerupted permanent teeth and ratained primary teeth.It can occurs almost anywhere in jaws. It is desirable that odontoma should be removed by surgical enucleation including follicle and surrounding soft tissues.Considering the age and behavioral cooperation of patient,the develoment of parmanent dentition,the location of odontoma in jaw,the need for the concomitant operative dentistry,operation is performed in outpatient department with/without sedation or under general anesthesia with endotracheal intubation. In this case report,2 patients with compound odontoma were treated by surgical enucleation including follicle and surrounding soft tissues.One patient,about 5years old,was treated under general anesthesia and concomitant operative density was performed.The other patient,about 11years old,was treated under local anesthesia in outpatient department.In 2 cases,after 4 months,surgical defects were filled with new bone and normalization of eruption path of impacted permanent teeth was observed.

2,4-pentanedione-2,4-dioxime, 2,4-pentanedione-2,3,4-trioxime의 Pd(Ⅱ) 및 Pt(Ⅱ) 착화합드르이 형성조건을 검토하여 본 결과 Pd(Ⅱ) 착화합물은 Dioxime과 Trioxime이 각각 pH 6~pH 10, pH 1~pH 8 범위에 서 Pt(Ⅱ)는 pH 1.4~7 범위에서 착화합물을 형성한다. 이 착물들은 중량분석법에 의하여 각각 1 : 2로 결합하여 PdD², PdT₂의 착물을 형성합을 알았다. Formation fo Palladium(Ⅱ) and Platinum(Ⅱ) complexes of 2,4-pentanedione-2,4-dioxime and 2,4-pentane-dione-2,3,4-trioxime were studied. The Pd(Ⅱ) complexes of dioxime and trioxime were precipitated in the range of the pH 6 to 10 and pH 1 to 8, and on the other hand Pt(Ⅱ) trioxime complex was precipitated in the range of the pH 1.4~7. The ratio of metal ions to ligands is found to be 1 : 2 complexes, PdD₂, PdT₂ and PtT₂by the gravimetric analysis.

장애인의 치과치료시 행동조절 : 전신 마취하의 치과치료

이긍호 大韓小兒齒科學會 1994 大韓小兒齒科學會誌 Vol.21 No.2

1977년 Snow는 전신 마취란 마취약제에 의해 전신에 걸쳐 통각을 상실토록함과 동시에 무의식 상태로 유도되는 것으로 정의했고, 이후 전신마취는 무통, 기억상실, 방사억제의 최면, 안전하게 외과수술을 할 수 있도록 골격근육의 조절이 없는 상태가 이상적인 것으로 평가했다. 치과 영역에서는 1844년 N_2O-O_2로 전신마취를 시행하여 발치를 무통적으로 시행한 것을 효시로 1870년대 국소마취 출현과 더불어 치과에서의 마취는 치과 임상의 필수영역으로 인정하게 되었다. 국소마취의 발달과 약재 개발로 동통조절을 목적으로 이용되었던 전신마취는 급격히 감소를 보였으나 치과 공포와 불안조절, 장애인의 행동조절의 한 수단으로 점차 이용빈도가 높아지고 있다.
