DIFFERENCE OF CALCIUM FLUORIDE FORMATION BETWEEN THE ENAMEL AND DENTIN AFTER FLUORIDE APPLICATION IN VITRO

THE JOURNAL OF THE KOREAN ACADEMY OF PEDTATRIC DENTISTRY (1998)

Jae-Gon Kim Seon-Ja Kweon Hyun-Du Yun Soo-Hyeon An Byeong-Ju Baik

The purpose of this study was to compare the amount of calcium fluoride deposited on the enamel and dentin surface and to obtain information on the morphological change and crystallographic details of mineral deposition after 12,000ppm APF application in vitro. The bovine enamel and dentin blocks were randomly assigned to eight groups according to artificial caries lesion formation and difference of fluoride application time. The fluoride concentration and morphological characteristics on the treated enamel and dentin surface were investigated by using fluoride quantitative analysis and SEM. The powdered enamel and dentin of the intact bovine incisors were prepared for the X-ray diffraction analysis. The following results were obtained. 1. The amounts of KOH-soluble fluoride on the carious enamel and dentin surface after 24h APF application were higher than after only 5min APF application(p0.05). The fluoride content was highly increased in the carious dentin as compared with sound dentin after APF application(P

Effects of Lactic Acid Bacteria Added in the Salted Squid and Fermented Oyster Products on Microbiological and Sensory Qualities during Storage

Current Topic in Lactic Acid Bacteria and Probiotics (2021)

Jae-Gon Kim Gyeong-Hwuii Kim Min-Sun Kim Myung-Hyun Lee Geun-Ah Kim

The salted fish or seasoned-fermented shellfish, jeotgal, is traditionally prepared for a long time and popular as a side dish for Koreans. However, high salt content is known as a key factor to hinder its sales in current health-conscious society. Based on the guideline of Korean Standards, the fermented or seasoned fish products including salted-seasoned squids should contain fish as a raw material more than 75% in the products. An immunostimulatory LAB strain, which was characterized by this research group, was deliberately added into both the squid and the oyster samples for examining quality change during storage. 300 g of each sample was divided into two storage conditions: 5˚C and room temperature, 20˚C. As a result, all the samples with LAB tend to increase in viable cell counts under room temperature preservation, especially in the fermented oyster samples with LAB increase 100 times after 2 weeks storage. On the other hand, it was noted that general bacterial counts maintain almost constant in all the samples irrespective to addition of LAB. Judging from the bacterial examination, the addition of LAB in the squid and the fermented oyster samples neither affects the changes of LAB and general bacterial counts nor inhibits the bacterial growth in this experimental settings. It is not expected the increase in LAB added during the usual shelf life of the commercial products. Compared to non-LAB samples, overall acceptance was significantly better for the samples added LAB. In conclusion, this experiment suggests that addition of LAB is strongly recommended to develop low-salt fermented fish and shellfish products of higher sensory qualities.

Extraction of cyanide from soil using alkaline phosphate solutions

Choi YoungWoo Lee JungWha Jae-Gon Kim R. J. Gilkes N. Prakongkep

A large amount of cyanide has been produced and used in a variety of industrial processes such as metal plating, gas production, mining and pigment production. Cyanide in the environment has attracted a concern due to its high toxicity. Toxicity and mobility of cyanide in soil strongly depend on its form. Chemical oxidation and biological degradation are commonly adopted for the remediation of cyanide contaminated soil. The chemical oxidation with the direct injection of oxidants revealed a limited remedial efficiency due to the degradation of oxidants by organic matter, manganese oxide and sulphide and to the low oxidation rate of adsorbed metal cyanide complex and solid metal cyanide. A new oxidation technology combined with soil washing to improve remedial efficiency is under development. For the first step in technology development, we tested the soil washing efficiency of alkaline phosphate solution. The tested solutions were 0 – 100 mM Na-orthophosphate, Na-hexametaphosphate and Na-pyrophosphate and the solution pH was adjusted to be 10 – 12 with 1N NaOH and 1N HCl. The kinetic study and the washing efficiency test were tested 1soil and 5washing solutions. After the reaction, the pH and the concentrations of cyanide species (free, weak acid dissociable, strong acid dissociable) and metal of washing solution were determined. The cyanide extraction sharply increased with reaction time for 100 minutes and then the cyanide extraction slowly increased. The cyanide extraction increased with pH and phosphate concentration. The cyanide extraction efficiency of phosphate solution at the same pH follows: pyrophosphate > hexametaphosphate > orthophosphate. More than ninety percent of the total extracted cyanide was strong acid dissociable (SAD) cyanide. The optimum cyanide extraction solution among the tested solutions was pH 12_30mM pyrophosphate. However, the extracted As increased with increasing the cyanide extraction. It implies that an additional wastewater treatment process is required for As removal.

ERUPTION PATTERN OF THE MANDIBULAR FIRST MOLAR USING THE CONE BEAM CT

THE JOURNAL OF THE KOREAN ACADEMY OF PEDTATRIC DENTISTRY (2009)

Jeong-Keun Shin Jae-Gon Kim Byeong-Ju Baik Yeon-Mi Yang Jin-Woo Jeong

The purpose of this study was to investigate the eruption pattern of the mandibular first molar in sagittal, frontal and horizontal views using the cone beam CT scanning. CT images were obtained from healthy 83 children (42 boys, 41 girls) between 3 to 10 years of age with a normal dentition according to Nolla stage. 1. In the frontal and horizontal view, the intermolar width decreased continuously with stage and slightly increased at the last stage. 2. In the sagittal and frontal view, eruption distances from occlusal plane were observed the largest change between stage 5 and 7. 3. In the horizontal and sagittal view, mandibular first molar from distal surface of primary second molar moved distally between stage 4 and 6. 4. In the sagittal view, angle from occlusal plane to mesio-distal axis increased between stage 4 and 8. 5. In the frontal view, angle from occlusal plane to bucco-lingual axis increased continuously during all stage. 6. In the horizontal view, angle from midsagittal plane to long axis increased between stage 5 and 8.

ORTHODONTIC TRACTION OF AN IMPACTED MAXILLARY CENTRAL INCISOR

THE JOURNAL OF THE KOREAN ACADEMY OF PEDTATRIC DENTISTRY (2004)

Jae-Gon Kim Jin‐Woo Jung Byeong-Ju Baik Yeon-Mi Yang Jeong Yong Lee

Impaction is generally defined as the lack of eruption of a tooth after the normal age for the eruption. An impacted tooth may appear blocked by another tooth, bone, or soft tissue, but cause of tooth impaction is often unknown. The clinician should consider the various treatment options available : (a) No treatment and observation, (b) surgical exposure and orthodontic traction (c) auto transplantation (d) extraction. These cases were about the patients with delayed eruption of maxillary central incisor. We surgically exposed impacted tooth and guided it into normal position by the orthodontic traction. Especially, in case 1, #21 was ectopic impacted state with root dilaceration. It is required to examine further root development and alignment of dentition serially.

Cornelia de Lange syndrome is a disorder of unknown etiology resulting in an syndrome characterized by specific dysmorphic features. Therefore this syndrome is diagnosed only by clinical features and other examinations for diagnostic aim are not effective. There are general growth retardation, mental retardation, hypertrichosis, confluent eye brows, low hair line, broad nasal bridge, anteverted nose tip, malformed limbs, webbing of toes, heart defect, gastroesophageal reflux disease, ear and ocular problems. Features associated oral structures are micrognathia, delayed eruption of teeth, cleft lip, cleft plate, thin upper lip and downturned angles of mouth. These are cases about two children who visited Department of Pediatric Dentistry of Chonbuk National University because of dental caries with Cornelia do Lange syndrome.

BILATERAL SUPERNUMERARY TEETH IN THE MANDIBULAR INCISOR REGION; A CASE REPORT

THE JOURNAL OF THE KOREAN ACADEMY OF PEDTATRIC DENTISTRY (2004)

Sunghee Kim Jongha Park Yeon-Mi Yang Byeong-Ju Baik Jae-Gon Kim

Supernumerary tooth describes an excess of tooth number, which are found in primary dentition with 0.3-0.8%, permanent dentition with 1.0-3.5% prevalence. Their frequency is about 2:1 (male vs female) and 9:1 (maxilla vs mandible). However, occurrence is very rare in the incisor region of the mandible. We need a early diagnosis and appropriate treatment plan because of possibility of diastema, eruption failure, displacement, rotation of the associated permanent teeth, root resorption, dentigerous cyst with presence of the supernumerary teeth. This is a case report about two impacted supernumerary teeth found in madibular anterior region of 6 years old girl. One was extracted and another was retained because of fusion with permanent central incisor on the labial surface.

IMPACTED MANDIBULAR CANINES; CASE REPORT

THE JOURNAL OF THE KOREAN ACADEMY OF PEDTATRIC DENTISTRY (2003)

Byeong-Ju Baik Jeong-Ah Seo Jongha Park Yeon-Mi Yang Jae-Gon Kim

Impacted mandibular canines are less common than impacted maxillary canines. The proceeding studies show that impacted mandibular canines occur in approximately 0.1% of patients examined. The causes of impacted mandibular canines are inadequate space, premature loss of the primary dentition, excessive crown length, hereditary factors, functional disturbances of endocrine glands, tumors, and traumas. The basic choices for treatment of those cases are orthodontic migration or surgical removal. This is a case report about those two different treatment methods. One patient was 11 years old female who had treated with surgical approach and the other was 14 years old male who had received orthodontic treatment.
