Streptococcus parasanguinis is a Viridans group bacteria that is most often discovered in the oral cavity and causes dental plaque and endocarditis in a rat model. It has low virulence but an unknown relationship to human respiratory infections. We report on a 61-year-old woman who developed hemoptysis followed by pleuritic chest pain after conscious sedation during a gastroscopic polypectomy and was diagnosed with pneumonia and parapneumonic effusion from Streptococcus parasanguinis isolated in pleural fluid. Microaspiration during the procedure was presumed to play a role in the pathogenesis.

Supernumerary teeth develop from excessive proliferation and development of the dental lamina. Supernumerary teeth can cause several problems, including ectopic eruption, delayed eruption, root resorption of adjacent teeth, and diastema. Supernumerary teeth in infancy are rare and have rarely been reported. Case of a 2-day-old infant with 3 supernumerary teeth is presented here and the patient was followed up for 21 months. The erupted supernumerary tooth in the primary dentition was extracted under moderate sedation at the age of 14 months. Microcomputed tomography analysis of the extracted tooth confirmed microscopic root malformation. After extraction, the midline diastema was reduced and oral hygiene improved. Early diagnosis and prompt treatment can prevent complications of supernumerary teeth.

To identify the trend of pediatric dentistry in USA and Japan, closely related to Korean pediatric dentistry. The Japanese Journal of Pediatric Dentistry(JJPD) and The Journal of the American Academy of Pediatric Dentistry(PD) were reviewed. We collected the bibliographical data of the articles published in the two journals from 1991 to 2000. We analyzed thematic distributions and chronological changes, and then compare those of two groups. The following results were obtained: 1. The 869 articles were published in JJPD and 672 in PD. This was about 30% more in JJPD. 2. In both JJPD and PD, the case reports were a quarter of scientific articles in quantity. 3. The studies on the systemic diseases had the highest proportion in both JJPD and PD. The studies on the dental caries and restorative materials also had high proportion in both journals. 4. The studies on the sedation and biochemical survey had high proportion in PD when had low proportion in JJPD. To the contrary, The studies on the behavior science in JJPD were about double of those in PD. 5. There was no statistically significant difference in quantity between JJPD and PD in the studies on the dental caries, prevention of dental caries, community dental survey, conservative treatment, restorative materials, pulp treatment, diagnosis and treatment of malocclusion, oral pathology and minor surgery, local anesthesia and nerve tissue, traumatic injuries. 6. There was statistically significant increase in the studies on the dental equipment in JJPD and in those on restorative materials in PD. 7. There was statistically significant decrease in the studies on the prevention of dental caries and local anesthesia and nerve tissue in JJPD, and those on conservative treatment in PD.

Chloral hydrate is one of the most widely used sedative agents to control the difficult to treat young age group in the dental clinic. We are often frustrated to see the patient still awake and cry with agitation even after far more than the normal onset time. In such a case, the patient has to be rescheduled for another sedation visit with different agents and/or routes which greatly disappoints the guardians. This case report presents a sedative regimen that can possibly help the clinician complete scheduled treatment without postponement. We have tried sleep induction with Enflurane (1-1.5vol%) for 60 seconds to 37 patients of those who failed to respond properly to the dose(70mg/kg)of oral Chloral hydrate. The average age and weight of the patients was 34.3 months(22-43mo.) and 14.9kg(11-21kg) respectively. It is suggested that sleep induction with low dose Eflurane produced a stable state during dental treatment with respect to vital sign and behavior. Evidence of adverse effect was not detected or reported during and/or after the procedures.

Traumatic injuries to the primary dentition are commonly encountered problems in dental practice. It is found that 30% of the children had injuries to the primary dentition and 22% to the permanent dentition. The greatest incidence of trauma to the primary dentition occurs at the ages of 2 and 3 as children start to learn motor coordination. Because teeth and alveolar bone are traumatized simultaneously, alveolar bone fractures are likely to occur when multiple teeth are involved in injuries. Dental splints are indicated for the management of maxillofacial fractures. They enable anatomic reduction of fractured segments and help immobilization and maintenance of the fragments after reduction. They also act as a stabilizer during rehabilitation. Various types of dental splints are available. In this case, routine resin-wire splint technique could not be applied because of the child's uncooperative behavior. Oral sedation was not indicated because N.P.O. had not been preceded. Therefore, we decided to use open-cap acrylic splint instead. Stabilization using open cap acrylic splint requires minimum chair time with reduced discomfort to both patient and dentist. It is an effective means of splint for uncooperative children and especially useful when other means of fixation have been failed. Because trauma on the primary dentition can affect the underlying permanent tooth germ, it is important to monitor eruption process of the permanent dentition.

Muscular dystrophy is a genetically heterogeneous group of disorders characterized by progressive muscle weakness of variable distribution and severity. Fukuyama type congenital muscular dystrophy (FCMD) is an unusual form of muscular dystrophy with autosomal recessive inheritance and is clinically characterized by an early age of onset, severe central nervous system involvement, facial muscle weakness, and multiple joint contractures. Muscular dystrophy is susceptible to perioperative respiratory, cardiac and other complications. Patients with FCMD have upper airway muscle weakness, therefore general anesthesia is preferred to sedation regarding maintaining the airway when treating these patients. The development of malignant hyperthermia in general anesthesia for patients with muscular dystrophy is a concern. Total intravenous anesthesia should be used instead of inhaled anesthetics because of the risk of malignant hyperthermia. A 3-year-9-month old, 13kg girl with Fukuyama type congenital muscular dystrophy was scheduled for dental treatment under general anesthesia. She had multiple caries and 14 primary teeth needed caries treatment. Prior to general anesthesia, oral premedication with 9 mg midazolam was given. General anesthesia was induced and maintained with target controlled infusion of propofol $3{\sim}3.5{\mu}g/mL$. The patient with progressive muscular dystrophy was successfully treated under total intravenous anesthesia with a target controlled infusion of propofol. There were no complications related to anesthesia and dental treatment during or after the operation. This case suggests that target controlled infusion of propofol is a safe and appropriate anesthetic technique in FCMD patients for dental treatment.

The purpose of this study was to assess the sedative effects of four kinds of medication for management in the uncooperative 64 children aged from 18 to 92 months(ASA class I) and weighting between 10 and 32 kg. They were given randomly a dose of chloral hydrate 75mg/kg and hydroxyzine 25mg orally(group 1), midazolam 0.1mg/kg intramuscularly and $N_2O$(group 2), group 1 with additional $N_2O$(group 3) and group 1 with additional midazolam 0.5cc intranasally(group 4), respectively. According to rating scale, sleep, crying, movement and overall behavior were checked for evaluation of the clinical sedative effects. They were restraind with Pediwrap and were monitored by pulse oximeter for safety during treatment period. The results were as follows : 1. In the evaluation of sleep, rating scale of chloral hydrate and hydroyzine combination group was superior to midazolam and $N_2O$ combination group(p<0.001), but there was no significant difference between chloral hydrate, hydroxyzine and $N_2O$ combination group and chloral hydrate, hydroxyzine and midazolam combination group. 2. In the evaluation of crying, movement and overall behavior, there were significant differences between chloral hydrate and hydroxyzine combination group and midazolam and $N_2O$ combination group(p<0.05), but no significant difference between chloral hydrate, hydroxyzine and $N_2O$ combination group and chloral hydrate, hydroxyzine and midazolam combination group. 3. In the evaluation of overall behavior, the mean score of chloral hydrate and hydroyzine combination group was 2.94, midazolam and $N_2O$ combination group 2.07, chloral hydrate, hydroxyzine and $N_2O$ combination group 2.47 and chloral hydrate, hydroxyzine and midazolam combination group 2.24, respectively. 4. Evidence of adverse effect was not detected or reported during and/or after dental treatment.

The purpose of this study was to compare the clinical sedation effect of chloral hydrate and hydroxyzine combination with and without nitrous oxide/oxygen inhalation when young children were sedated for dental treatment. The uncooperative 20 children aged, 21 to 47 months of age(ASA Class I), participated in the study. The author examined 20 children(male 12, female 8). Each patient was assigned to receive chloral hydrate(50mg/kg) and hydroxyzine(25mg). Next appointment, each patient was assigned to receive $N_2O-O_2$, choral hydrate and hydroxyzine. Sleep, crying, movement, and overall behavior response were evaluated, and the sedative effects were evaluated by Houpt's rating scale. Pulse rate and peripheral oxygen saturation were also measured for monitoring the sedated patients during treatment period by pulse oximeter. The result were as follows : 1. In the evaluation of sleep scores, crying scores, and movement scores, chloral $hydrate/hydroxyzine/N_2O-O_2$ combination group was significantly rated high(p<0.05). 2. In the evaluation of overall behavior scores, chloral hydrate/hydroxyzine/$N_2O-O_2$ combination group was significantly rated high(p<0.05). 3. In the evaluation of overall behavior evaluation scores(by Houpt), 93.3% in chloral $hydrate/hydroxyzine/N_2O-O_2$ combination group and 63.3% in chloral hydrate/hydroxyzine combination group were rated "good" or "very good". 4. There was no adverse side effect(i.e. respiratory depression) in both group.
Background: Establishment of laparoscopic cholecystectomy as an outpatient procedure has accentuated the clinical importance of reducing early postoperative pain, as well as postoperative nausea and vomiting (PONV). We therefore planned to evaluate the role of a multimodal approach in attenuating these problems. Methods: One hundred and twenty adult patients of ASA physical status I and II and undergoing elective laparoscopic cholecystectomy were included in this prospective, randomized, placebo-controlled study. Patients were divided into four groups of 30 each to receive methylprednisolone 125 mg intravenously or etoricoxib 120 mg orally or a combination of methylprednisolone 125 mg intravenously and etoricoxib 120 mg orally or a placebo 1 hr prior to surgery. Patients were observed for postoperative pain, fentanyl consumption, PONV, fatigue and sedation, and respiratory depression. Results were analyzed by the ANOVA, a Chi square test, the Mann Whitney U test and by Fisher's exact test. P values of less than 0.05 were considered to be significant. Results: Postoperative pain and fentanyl consumption were significantly reduced by methylprednisolone, etoricoxib and their combination when compared with placebo (P<0.05). The methylprednisolone + etoricoxib combination caused a significant reduction in postoperative pain and fentanyl consumption as compared to methylprednisolone or etoricoxib alone (P<0.05); however, there was no significant difference between the methylprednisolone and etoricoxib groups (P>0.05). The methylprednisolone and methylprednisolone + etoricoxib combination significantly reduced the incidence and severity of PONV and fatigue as well as the total number of patients requiring an antiemetic treatment compared to the placebo and etoricoxib (P<0.05). Conclusions: A preoperative single-dose administration of a combination of methylprednisolone and etoricoxib reduces postoperative pain along with fentanyl consumption, PONV, antiemetic requirements and fatigue more effectively than methylprednisolone or etoricoxib alone or a placebo.

The odontoma 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 retained 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 development of permanent 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 5 years old, was treated under general anesthesia and concomitant operative dentistry was performed. The other patient, about 11 years 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.
