The concept of resin infiltration which was born in an innovative philosophy to arrest the incipient caries. However, the structural changes of resin infiltrated lesions have not yet explained completely. The liquid resin might contribute not only to maximizing the penetration but to deteriorating physical stability. This study was performed to examine some physical and histological features of resin infiltrated incipient carious lesions. With the specimen of resin infiltrated lesions, microhardness by nanoindentation in depth profile, morphology of resin tags were revealed after HCl dissolution, and degree of microleakage were assessed. The percentage of microhardness of surface layer and lesion body of untreated specimen to sound enamel was 64.6% and 24.6% respectively, while that of resin-infiltrated lesions was 72.1%, showing significant difference (p<0.05). The resin tags observed under SEM had relatively homogeneous length of 433(282~501)
on the average. Among 20 specimens for microleakage assessment, 13 specimens showed no leakage while 5 and 2 showed leakage into outer and inner half of lesion respectively. It was thought the infiltrant resin penetrates deeply and homogeneously into lesion body and improves its hardness with relatively good physical stability.

Effect of supplementary intranasal midazolam on oral sedation of children The purpose of this study was to compare the cardiopulmonary parameters of two sedation regimens during dental treatment: (1) Oral chloral hydrate(CH) and hydroxyzine(HZ) with nitrous oxide-oxygen(
) inhalation(CH-HZ group); (2) Oral chloral hydrate(CH) and hydroxyzine(HZ) with nitrous oxide-oxygen(
) inhalation and supplementary intranasal(IN) midazolam administration(MIDA group). Among the patients of OO hospital who received dental treatment under sedation over the past 5 years, 44 patients were selected for each group of CH-HZ and MIDA according to their age, gender and weight. Following parameters that were recorded every 5 minutes were compared: 1) Heart rate(HR) 2)
saturation 3) End tidal carbon dioxide concentration(
) 4) Respiratory rate(RR) 33 patients of Group MIDA who have complete data of 15 minutes before and after supplementary IN midazolam administration were selected. And measurements 15 minutes before and after midazolam administration in same patient were evaluated. The results were as follows: 1. Heart rate was significantly higher in MIDA group than in CH-HZ group, but it was within normal range. 2. Comparing HR,
saturation, EtCO2, RR between before and after of supplementary IN midazolam administration in the same patient, the differences were not statistically significant.

To maintain good oral hygiene, plaque control is essential and the most common and effective method is appropriate brushing. However accurate brushing is so difficult for children that the importance of brush is getting higher. We investigated the effect of tooth brushing instruction in plaque control for 40 children who came to Kyunghee university dental hospital, department of pediatric dentistry. We examined basic information by self-assessment, evaluated plaque index, tooth & tongue cleanness, malodor index for 4 times and compared values before and after tooth brushing instruction. Plaque index decreased(p<0.01) and tooth & tongue cleanness increased(p<0.01). There were no significant differences in mal-odor index. In conclusion, tooth brushing instruction is effective in removing dental plaque and its beneficial role is highly expected in establishing children's good oral hygiene.

The purpose of this study was to find out the effect of dentifrice containing Horseradish (Armoracia rustica) root extracts on improvement of oral hygiene. The clinical evaluation was done participated by 80 adults volunteers who provided a informed consent for their participation. The participants were divided into two groups ; control group (using toothpaste without Horseradish extracts) and experimental group (using toothpaste containing Horseradish extracts). The checklist of the experiment includes the plaque index, gingival index and anti-caries activity. The anti-caries activity was measured by cultivating Streptococcus mutans for 48 hours then estimating the number of increased bacteria using Dentocult SM. The double-blind method was used in this study. The results of this study can be summarized as follows; 1. The plaque formation decreased 28% in control group, 58% in experimental group using dentifrice with Horseradish extracts compared to baseline data. 2. For gingival index, control group and experimental group showed 26% and 40% decrease compared to baseline data, respectively. 3. The score of caries activity test decreased by 4% for control group and 69% for experimental group compared to baseline data. According to the results, a dentifrice containing Horseradish extracts can improve oral hygiene.

Odontomas generally appear as small, solitary, or multiple radio-opaque lesions found on routine radiographic examinations. It is a comparatively common odontogenic tumor, and may lead to interfere with the eruption of its associated tooth. In general, odontomas occur more often in permanent dentition and are very rarely associated with primary teeth. This report deals with five rare cases of primary teeth impaction associated with odontomas, with spontaneous eruption occurring in all five cases after simple surgical removal of the odontoma. Impacted primary teeth may be associated with defects in development and eruption of their permanent successors, and thus long-term observation is necessary until the permanent successors erupt.

The concept of revascularization of necrotic pulps regained interest and became an alternative conservative treatment option for young permanent teeth with immature roots. Revascularization of immature teeth with apical periodontitis depends mainly on disinfection of the canal. Since the infection of the root canal system is considered to be polymicrobial, a combination of drugs would be needed to treat the diverse flora. A triple antibiotic mixture of metronidazole, ciprofloxacin, and minocycline was used as an intracanal medicament. However, discoloration was developed after applying the triple antibiotic mixture. It is believed that the marked discoloration is related to the use of minocycline. The aim of this article was to present cases of coronal discoloration after triple antibiotic therapy in immature tooth and was treated with bleaching technique to control coronal discoloration. In conclusion, revascularization by using triple antibiotics promotes a paradigm shift in treating endodontically involved permanent teeth. However, we should understand that triple antibiotics containing minocycline induces tooth discoloration. Further research to prevent coronal discoloration should be investigated and suggested for the safe use of triple antibiotics.

The anterior maxillary incisor is the most traumatized region in the mouth and trauma is frequent between the ages of 8-10. Traumatic loss of teeth, can lead to many complications in children. Thus, as possible to keep traumatic teeth, but if you need extractions There may be. Complications occur and early tooth loss is frequent. Complications of early loss of central incisors are esthetic compromise, loss of vertical and horizontal width, height, contour of alveolar bone, tilting of adjacent teeth, arch length loss. Alveolar bone loss may affect normal function and stability, and results in esthetic problem for future prosthesis restoration. The 9-year-old girl and 6-year-old boy got early loss of upper central incisor. The amount of alveolar bone resorption was measured using cone beam computed tomograph and cast analysis.

The crown-root fracture is defined as a fracture of tooth that contains enamel, dentin and cementum with or without pulp exposure. Generally the fracture lines place obliquely from labial surface, between incisal edge of the crown and marginal gingiva, to palatal surface subgingivally. If the fracture line is located supragingivally, the removal of tooth fragment and supragingival restoration can be performed. In subgingival fracture line, the surgical exposure, orthodontic eruption or surgical eruption can be considered. If the fracture line is too deep to restorate, extraction or decoronation can be selected. In children and adolescents, the extraction should be the last option. Another option to select before extraction is the restoration using fiber-reinforced post and the reattachment of tooth fragment. The fiber-rainforced post enhances the retention and the durability of tooth fragment. The reattachment of crown fragment using resin adhesive system is considered minimal invasive treatment biologically. This case reports the treatment of crown-root fracture using the reattachment of crown fragment and the insertion of fiber-reinforced post.

Autogenous tooth transplantation can be defined as the surgical movement of a tooth from one position in the mouth to another in the same individual. The most common reasons for tooth transplantation include replacement of a missing first molar, transplantation of impacted canines to their normal positions in the arch, and transplantation of premolars in areas of missing teeth, especially in the anterior area of the mouth. The key to successful tooth transplantation is proper selection of graft with adequate root development as well as the design of surgical operation. Root development stage with half to three-quarter-developed roots increase the success rate of autotransplantation. We report the cases of successful autotransplantation which resulted in ideal healing of periodontal ligament, gingiva and alveolar bone. All transplanted teeth presented immature root formation at the moment of the procedure. After surgical procedure, we can observe good healing pattern without endodontic problem.

Complex odontomas consist of a conglomerate mass of enamel, dentin and cementum which bears no anatomic resemblance to a tooth. The majority of these lesions are completely asymptomatic, being discovered on routine radiographic examination or when films are taken to determine the reason for tooth eruption failure. Compound odontomas seldom cause bony expansion, but complex odontomas often cause slight or even marked bony expansion. Complex odontomas are mostly associated with permanent teeth and very rarely associated with deciduous teeth. They are usually located in the first-or second-molar areas of the mandible. This report presents a case of a patient with impaction of a maxillary primary canine by a complex odontoma in which surgical excision of the lesion was performed. And the primary canine was repositioned right under gingival level for spontaneous erution. Follow-up after six months showed spontaneous eruption ofthe repositioned maxillary primarycanine.

Burkitt's lymphoma is a malignant tumor originated from B lymphocyte and a type of non-hodgkin lymphoma. It is clinically classified by endemic, sporadic and immune deficient forms. In the past, it had poor prognosis but in recent years survival rate is 50~80% treated by intensive chemotherapeutic regimens. Mostly it is a lesion of the jaws. Clinical symptoms are severe tooth mobility, displacement, gingival redness and swelling. This case is about a patient with aggressively progressing Burkitt's lymphoma of the jaws. Initial diagnosis was done in dental hospital and it has shown satisfactory outcome by prompt and appropriate treatment.

The radicular cyst is the most common odontogenic cyst which is caused by pulpal inflammation, pulp death, and secondary to trauma or dental caries. Usually, the radicular cyst is asymptomatic, but a secondary inflammation can cause pain, swelling and redness. Getting larger, the radicular cyst can cause facial asymmetry and paresthesia by pressure on nerves. It requires conservative endodontic treatment or surgical approach. When the size of cyst is large or invasion of the adjacent tissue is not expected, cyst enucleation is carried out. And most of the case can be completely cured and shows low recurrence. In these radicular cysts cases, by cyst enucleation or apicoectomy after root canal treatment simultaneously, the infected teeth can be preserved successfully.

Supernumerary tooth occurs most frequently at premaxilla area. Followed by mandibular premolar area, mandibular fourth molar area, maxillary paramolar area. Mesiodens are mainly impacted in the palatal area and surgical approach is made at palatal side. The time of surgery remains controversial. In case of inverted or horizontal impacted supernumerary tooth, intraosseous tooth movement and vertical growth of premaxilla makes surgical extraction more difficult. And also the more quantity of removed bone is, the higher degree of difficulty is. Inverted mesiodens of these cases were impacted superior to apex level of adjacent permanent incisor. Although CT examination revealed exact location of impacted tooth, surgical procedure including ostectomy may take a long time more than expected. So, before surgical extraction, it's need to be considered several factors such as necessity of CT taking, degree of difficulty, direction of surgical approach, necessity of general anesthesia etc.

Odontoma is a mixed tumor formed by the overgrowth of ectodermal epithelial cells and mesodermal cells. It arises during normal tooth development and only grows to a certain level. It is not a true neoplasm and therefore it is considered as hamartomas. Odontomas are classified into compound and complex types based on morphology. Compound odontoma is commonly found in the anterior region of the maxilla, and has a radiopaque lesion that resembles small teeth. Usually, odontoma is treated by conservative surgical removal and there is little probability of recurrence. This paper describes three cases of compound odontoma diagnosed in children with 1 year of follow-up. These case reports present patients having eruption disturbance of primary and permanent teeth due to the presence of compound odontoma. In order to induce spontaneous eruption, conservative surgical removal was performed showing favorable results.
