Monitoring of patients is essential in assuring the safety of sedation in the dental office. The purpose of this study was to explore the utilization and preferences of sedation, utilization of monitoring methods, and the preparation for emergencies during sedation. Members of the Korean Academy of Pediatric Dentistry were surveyed(n=245) from 1998. 10. 1 to 1998. 12. 20 to establish current trends in the use of sedation practices and monitoring methods in Korea. Findings of the survey include: 1. Twenty nine percent of pediatric dentists use sedative agents in their practices. Seventy one percent of pediatric dentists do not use any sedative agents in their practices 2. Thirty nine percent of pediatric dentists who use sedative agents do so without monitoring devices 3. Nitrous oxide inhalation sedation was the most frequently utilized sedation method by pediatric dentists and chloral hydrate was the most frequently utilized sedative by pediatric dentists. Pulse oximeter was the most frequently utilized monitoring method during sedation in dental office. 4. Only twenty eight percent of pediatric dentists obtain the informed consent of the child's legal guardian. 5. Only sixty percent of pediatric dentists prepare for emergencies during sedation.

There are some problems in inhalation sedation of non-cooperative pediatric patients. Usually the pediatric patients reject the nasal hood and there's no cooperation for administration of nitrous oxide gas. In mouth breathing patient, other technics of sedation such as intravenous or oral sedation or general anesthesia were recommended. Common causes of mouth breathing are common cold, allergic rhinitis, sinus problem, anatomical disorder, and habitual mouth-breathing. However in some patient not indicated the general anesthesia and high failure rate in oral and intravenous sedation. Administration of
with suction catheter was applied in full mouth breathing patient. Clinically effective sedation were occurred during procedure about 45 to 55 minutes. There's no any side effects by
inhalation sedation. The patients awoke at the end of the procedure and received 100% oxygen for 2-3 minutes. There's still some problems in use of the suction catheter such as air pollution of operation theater and elevate arterial carbon dioxide tension.

The purpose of this in vitro study was to evaluate the efficacy of self-etching primer which was developed to simplify the bonding procedures by measuring the shear bond strength and observing the interfacial morphology. 90 flat dentinal surfaces were prepared by grinding the buccal and lingual areas of caries-free human deciduous molars. After bonding of composite resin to sample surfaces according to the manufacturer's direction and thermocycling, shear bond strengths were measured using Universal testing machine(Instron). Another groups of specimens were treated by hydrochloric acid to secure the resin only and those tags were evaluated under SEM for their length and forms and the morphology of the bonding sites were also observed. The result as follows. 1. Group III showed higher shear bond strength than group I and II but no statistically significant difference was founded between group I and II(p>.05). 2. Adhesive failure was predominant in group II whereas dentin detachment was the main failure pattern in group I and III. 3. Relating long resin tags of
were observed in samples of all groups under SEM. In group I, homogeneously long resin tags were arranged rather tight whereas rather loosely arranged resin tags of various length were found in group II. Lateral branching of resin tags was the characteristic finding observed in group III.

At the department of Pediatric Dentistry in Chonbuk National University Hospital, authors conducted a survey of 50 new patients and 100 new parents regarding fluoride in order to discover what they think about fluoride. The results obtained were as follows ; 1. It answered patients 26% parents 51% and total 42.7% in knowledge about the use of fluoride in dental clinics 2. The knowledge about caries prevention effect of fluoride is high, patients 86%, parents 85% and total 85.3% 3. The patients and parents who wanted to use fluoride are 46%, 44% respectively 4. The patients and parents who experienced fluoridation are 60%, 55% respectively 5. It is not correspond the knowledge about caries prevention effect of fluoride and the practical method of application These results suggest that the number of patients and parents who use fluoride will increase if we advise them adequately.

The primary objective of pulp treatment is to maintain the integrity and health of the oral tissues. The most important and difficult aspect of pulp therapy is determining the health of the pulp, or its stage of inflammation, so that a decision can be made regarding the best form of treatment. Immature permanent teeth are good candidates for many pulp healing procedures, due to their rich blood supply, which is believed to enhance the pulp's ability to react successfully to various insults. Healing was considered to have taken place when the tooth fulfilled the following criteria: 1. Abscence of clinical symtoms 2. Radiographic evidence of dentin bridge formation 3. No intrapulpal or periapical pathosis was evident radiographically 4. Continued root development and closure of the apex in immature teeth 5. Normal dentin apposition in mature teeth 6. Positive response to electrical pulp test This presents a report of cases in which immature permanent teeth, pulp-exposed by caries or trauma, was treated successfully by partial pulpotomy.

The definition of fascial spaces are latent spaces between fascial planes. If infections which spread from dental origin to soft tissue are mild, they are restricted by fascial planes. But, when infections are severe, fascial spaces are often used as a natural pathway which spread to the deep cervical region. If they are not treated at early stage, they may result in the fatal complications as followings; airway obstruction, septicemia, cerebral abscess, and thrombophlebitis etc. The early treatment of fascial space abscess is very important for young children. These case reports present the successful result of fascial space abscess treatment through intracanal drainage without surgical excision. It is proven that the treatment through intracanal drainage has some benefits to the surgical excision, which are as follows: 1) It is economic to the patients or their parents avoiding admission. 2) The treatment procedure is more simple. 3) Childrens can avoid the fearful environment.

Transposition has been described as an interchange of position of permanent tooth and is a relatively rare dental anomaly. Transposition of teeth may occur both in the maxillary and mandibular arches. but it appears more often in the maxilla of individual teeth, the maxillary canine is the most often involved. A canine transposes most often with a first premolar and less frequently transposes with a lateral incisor. Incomplete transposition is a condition describing an interchange in the position of the crowns of two permanent teeth, while the root apices remain in their relative position. Complete transposition is a situation in which both the crowns and entire root structure are transposed. The etiologic factors of transposition are tooth buds interchange, retained deciduous canines, migration of the erupting canine, trauma to deciduous teeth etc. This report describes a case of a transposition between a maxillary left canine and a lateral incisor and impaction of a maxillary left central incisor due to trauma to deciduous dentition.

Ectodermal dysplasia is a genetic birth defect in which at least abnormally develop two structures derived from the ectoderm. It is usually inherited in autosomal dominant or autosomal recessive pattern. Oral manifestations are oligodontia, anodontia, dysmorphic teeth(conical shape), decreased occlusal vertical dimension and alveolar bone. Extraoral signs may include decreased or absent sweat glands, sparse and fine hair, saddle nose, hearing loss and decreased production of body fluids including saliva. Most affected children require extensive dental treatment to restore their appearance and help the development of a positive self image. The patient's overclosed profile was due to a decreased vertical dimension. The use of overdenture is to preserve erupted teeth, to accomodate the newly constructed occlusal plane, to improve retention and stability of denture and to maintain the remaining alveolar bone. The restoration of vertical dimension improved the child's speech, swallowing, and eating. Growth continue until the age of approximately 18. As child grows, replacement dentures will have to be fabricated primarily to accomodate increasing vertical dimension and changing dentition. Implants may be indicated later if the alveolar bone is adequate. Periodic recall visits are advised, to monitor the dentures during periods of growth and development, and eruption of the permanent teeth.

It is a relatively common clinical experience to see an unerupted maxillary central incisor. This phenomenon is apparent at the dental age of almost eight years and over. Among the possible cause for failure of eruption, ectopic development of the tooth germ is mentioned. This is not fully understood but trauma or periapical imflammation of primary predecessors is accepted. The case with no history of trauma may be impacted by the periapical imflammation of primary predecessors. For bringing into the tooth eruption and the continued normal root developement by the Hertwig's epithelial root sheath, there are early considered of surgical invention and orthodontic traction with removable appliance. We reported successful treatment for inverted maxillary central incisor with proper eruption and normal root developement by forced eruption using removable appliance. But further observation will be required to evaluate the final root developement state and amount of keratinized attachment gingiva.

Craniosynostosis, the premature fusion of cranial sutures, presumably involves disturbance of the interactions between different tissues within the cranial sutures. Interestingly, point mutaions in the genes encoding for the fibroblast growth factor receptors(FGFRs), especially FGFR2, cause various types of human craniosynostosis syndromes. To elucidate the function of these genes in the early morphogenesis of mouse cranial sutures, we first analyzed by in situ hybridization the expression of FGFR2(BEK) and osteopontin, an early marker of osteogenic differentiation, in the sagittal suture of calvaria during embryonic(E15-E18) and postnatal stage(P1-P3). FGFR2(BEK) was intensely expressed in the osteogenic fronts, whose cells undergo differentiation into osteoprogenitor cells that ultimately lay down the bone matrix. Osteopontin was expressed throughout the parietal bones excluding the osteogenic fronts, the periphery of the parietal bones. To further examine the role of FGF-mediated FGFR signaling in cranial suture, we did in vitro experiments in E15.5 mouse calvarial explants. Interestingly, implantation of FGF2 soaked beads onto both the osteogenic fronts and mid-mesenchyme of sagittal suture after 36 hours organ culture resulted in the increase of the tissue thickness and cell number around FGF2 beads, moreover FGF4-soaked beads implanted onto the osteogenic fronts stimulated suture closure due to an accelerated bone growth, compared to FGF4 beads placed onto mid-mesenchyme of sagittal suture and BSA control beads. In addition FGF2 induced the ectopic expression of osteopontin and Msx1 genes. Taken together, these data indicate that FGF-mediated FGFR signaling has a important role in regulating the cranial bone growth and maintenance of cranial suture, and suggest that FGF-mediated FGFR signaling is involved in regulating the balance between the cell proliferation and differentiation through inducing the expression of osteopontin and Msx1 genes.

Mucocele is clinical term used to describe swelling caused by the pooling of saliva at the site of a severed or obstructed minor salivary gland duct. Mucoceles are categorized into two subgroups, extravasation type and retention cyst type. The etiology of extravasation type mucocele is related to mechanical trauma to the minor salivary gland excretory duct, resulting in extravasation of mucus into the fibrous connective tissue so that a cyst-like cavity is produced, but the epithelial lining is absent. Retention cyst type mucocele results from obstruction of minor salivary gland excretory duct, and cystic cavity is lined by epithelial cells. This case report presents a mucocele occurred on the lower lip, and caused by suture silk unremoved for 3 years. Suture silk penetrated and tore the minor salivary gland duct on the lower lip with subsequent extravasation of mucus into the fibrous connective tissue.

The dentigerous cysts originate through alteration of the reduced enamel epithelium after amelogenesis is completed, with accumulation of fluid between the layers of the enamel epithelium, or between this epithelium and the tooth crown. Next to the radicular cyst, they are the second most common type of odontogenic cyst. They occur over a wide age range with a peak frequency in the 2nd to 3rd decade. A substantial majority involve the mandibular third molars, followed in order of frequency by the maxillary permanent canines, mandibular second premolars, and maxillary third molars. With regard to the treatment of these cysts, the marsupialization procedure with obturator is recommended during the age when the eruptive force of the teeth is still strong. It can be effective when preservation of the displaced teeth is desirable. We treated the dentigerous cyst by marsupialization with obturator and guided the eruption of involved teeth to normal position. And we got the results as follows : 1. Severely dislocated teeth associated with dentigerous cyst erupted into proper position. 2. The enamel hypoplasia and the root deformity were observed some cases. 3. The bone expansion and defect were healed without infection and recurrence.

This study was performed to evaluate the effect of aging and thermal cycling on the tensile strength of six commercially available glass-ionomer materials: two chemically set glass-ionomer materials(Fuji II, Fuji IX), two resin-modified glass-ionomer materials(Fuji II LC, Vitremer), and two polyacid-modified composite resins(Compoglass, Dyract). Rectangular tension test specimens were fabricated in a teflon mold giving 5mm in gauge length and 2mm in thickness. All samples were divided into 3 groups. Group 1 was immersed in a
distilled water for 1 hour. Group 2 was immersed in a
distilled water for 30 days. Group 3 was subjected to 10,000 thermal cycles between
, and the immersion time in each bath was 15 seconds per cycle. Tensile testing was carried out at a cross-head speed of 0.5mm/min and fracture surfaces were examined with scanning electron microscope. The results obtained were summarized as follows; 1. The polyacid-modified composite resins were stronger than the resin-modified glass-ionomer materials, which were much stronger than the conventional glass-ionomer materials. 2. Tensile strengths were slightly increased after aging treatments for 30days. 3. Tensile strengths of conventional glass ionomers were significantly increased after thermal cycling treatment(p<0.01). 4. The highest tensile strength value of 45.4MPa was observed in the Dyract group and the lowest value of 13.3MPa was observed in the Fuji II LC group after the thermal cycling test, and the strengths of polyacid-modified composite groups were significantly higher than those of other groups. 5. The highest characteristic strength value of 48.6MPa was obtained in the Dyract group, however the highest Weibull modulus value of 8.9MPa was obtained in the Compoglass group after thermal cycling test.

The purpose of this study was to investigate the revascularization and reinnervation of calcitonin gene-related peptide immunoreactive nerves in immediately replanted rat molars. First maxillary right molars in 56 rats(35days old) were extracted and immediately replanted. The rats were killed 1, 2, 3, 7, 14, 28 and 42 days after replantation and revascularization of pulpal blood vessels were examined microangiogram with korean traditional ink and reinnervation of pulpal nerve were examined immunohistochemical method using calcitonin gene-related peptide(CGRP) antiserum. The results were as follows; 1. Revascularization and reinnervation of CGRP immunoreactive nerve fibers were observed mesial side whole pulp tissue of replanted teeth. Revascularization and reinnervation of CGRP immunoreactive fiber were made at 2days after replantation in entire pulp of replanted teeth and the distribution density of blood vessels were gradually increased according time elapsed, but did not achieve the density of control. 2. Postoperative dentin formation in replanted teeth revealed at 1week after replantaton and gradually increased according to time elapsed. 3. Revascularization and Reinnervation of CGRP immunoreactive nerve fibers were established at the same time and it seems to be closed relatationship between revascularization and reinnervation.
