This study aims to analyze dental care at the 25th World Scout Jamboree (WSJ) using a predesigned standardized dental chart to provide a reference for the operation of dental emergency clinics at future large-scale youth events. The dental charts of all patients treated at the 25th WSJ emergency dental clinic were examined. Fisher’s exact tests were used to analyze the differences between youth scouts and adult leaders. Eighty visits of 71 patients were included in the study. The largest number of patients was from Asia-Pacific (49.3%), followed by patients from Europe (40.8%). In terms of chief complaints, oral ulcers (19.7%), lesions of the lips (18.3%), and orthodontic discomfort (15.5%) were the most prevalent. The analysis showed a significant difference (p = 0.0023) between youth scouts and adult leaders in the distribution of patients in the first half (July 30th - August 3rd) and second half (August 4th - August 8th) of the event. There was a higher incidence of dental conditions associated with hot and humid environments, unlike typical emergency dental settings. Therefore, despite adequate preparation, unexpected dental visits may occur, and it is recommended that operations be conducted in community-based dental hospitals to allow for immediate and efficient responses in international camps.

Temporomandibular joint disorders (TMDs) can occur at any age, including childhood and adolescence, and pain-related TMDs can affect growth and quality of life. In the present study, recent trends in the diagnosis and treatment of TMDs in children and adolescents were analyzed over a 10-year period. Using 10 years of data from the Health Insurance Review and Assessment Service (HIRA) and Jeonbuk National University (JBNU) Dental Hospital, patients between 0 and 19 years of age diagnosed with K07.6 (temporomandibular joint disorders) were analyzed by 5-year bins. Both datasets indicated a higher prevalence in females (1.2-fold in HIRA, 1.5-fold in JBNU) and in ages 15 to 19 years (72.1% in HIRA, 74.7% in JBNU). HIRA reported a 42.3% increase in prevalence per 100,000 people, from 651.4 in 2011 to 927.0 in 2020. JBNU reported K07.66 (masticatory muscle disorders) as the most common diagnosis in subjects under 10 years of age and K07.60 (internal derangement of temporomandibular joint) in those over 10 years of age. In addition, both were treated mainly by a combination of physical therapy and medication, and the treatment rate increased in accordance with age. Because TMDs can affect various structures in the orofacial region and cause pain that tends to differ with age, an early and specific diagnosis appropriate for age is important for treatment. Therefore, pediatric dentists need to promptly recognize TMDs in children and adolescents and consult with specialists as the prevalence increases.

The purpose of this study was to investigate pediatric emergency department visits patterns and characteristics of children and adolescents under the age of 20 in South Korea from 2002 to 2015 due to dental conditions. This study used a stratified sample of approximately 1 million people from the Health Insurance Review and Assessment Service Database. The age, region, household income, and treatment cost were included for the patient characteristic analysis. Pediatric patients were compared to the adult group (over 20 years old).In children and adolescents, the rate of emergency department visits due to dental conditions was higher for traumatic conditions than for non-traumatic conditions. Children and adolescents with higher household income visited the emergency department more often than those with lower household income. The region with the highest number of children and adolescents visiting the emergency department for dental conditions was Busan (per 100,000 population).Although this study could not confirm the annual trend of children and adolescents’ dental emergency visits due to the sample size limitation, the characteristics of children and adolescents’ dental emergency visits were compared with those of adults using a stratified sample.

The aim of this study was to investigate the risk factors associated with sleep disordered breathing (SDB) by comparing intraoral factors, body mass index (BMI), and medical history with pediatric sleep questionnaire (PSQ) findings.Seven hundred eighty-seven subjects aged between 7 to 11 years old were included. Their caregivers were asked to complete questionnaires. Oral manifestations including Angle’s classification, overjet, and Brodsky tonsil grade were examined. Children with PSQ scores of more than 0.33 points were classified into the SDB high-risk group.Among the 787 subjects, 34 (4.3%) were classified into the SDB high-risk group. Children with allergic rhinitis, atopic dermatitis, excessive overjet, or large tonsil size had a significantly higher risk for SDB versus those without. Also, there was a significant difference in SDB risk according to BMI status. Gender, gestational age, breastfeeding, and Angle’s classification were not associated with SDB.Children at high risk for SDB were predisposed to tonsillar hypertrophy, allergic rhinitis, obesity, and atopic dermatitis. Children with these factors could be candidates for early intervention to prevent the progression of SDB.

This study aims to identify the clinical characteristics for diagnosing streptococcal pharyngitis. The correlation between eighteen clinical manifestations and rapid antigen detection test results was analyzed. Among 205 patients, five clinical manifestations, pharyngeal hemorrhage (odds ratio [OR] = 11.85), palatal hemorrhage (OR = 9.32), tonsillar swelling (OR = 4.37), rash (OR = 3.02), and enlarged cervical nodes (OR = 1.91), were significantly correlated with group A Streptococcus (GAS) pharyngitis. Traditional indicators such as fever, pharyngeal redness, acute onset, headache, rhinorrhea, cough, tonsillar exudate, and cervical tenderness were not statistically related to GAS pharyngitis. Therefore, physicians should be cautious in using these traditional indicators

Background: Group A streptococcus (GAS) is the most common cause of bacterial pharyngitis. This study aimed to characterize the molecular epidemiology of GAS infection using an emm-typing and emm-clustering approach. Methods: A total of 372 patients from Changwon who showed pharyngitis symptoms were recruited during the sampling period of 2018–2019 and throat cultures were obtained from them. emm typing was performed using polymerase chain reaction (PCR) and direct sequencing. emm genotypes and GAS clusters were classified based on a web-based database. Results: Of the 372 throat swab specimens, 101 (27.2%) were positive for GAS. emm typing analysis was performed on 59 GAS isolates. The most prevalent emm type was emm89 (20.3%), followed by emm12 (16.9%). Seven emm clusters were identified: E4 (emm89/ emm28, 32.2%), A-C4 (emm12, 16.9%), E1 (emm4, 13.6%), A-C5 (emm3, 10.2%), E6 (emm75, 8.5%), M6 (emm6, 8.5%), and A-C3 (emm1, 6.8%). Conclusion Diverse and temporal changes were observed in the distribution of emm types and clusters of GAS. Continuous surveillance based on emm genotyping is needed to monitor the epidemiological characteristics of GAS pharyngitis.

The purpose of this study was to investigate trends in dental sedation of Korean children and adolescents.
A retrospective study was conducted on patients under 20 years of age who received dental treatment under sedation using National Health Insurance Service-National Sample Cohort Database from 2002 to 2015. Based on the 1 million standard data, there were 436 cases of dental treatment under sedation in 2002, but 4002 cases in 2015, showing a trend increasing every year. The 3 - 5 year old group accounted for the largest portion (54.2%), while the 6 - 8 year old group increased recently. Nitrous oxide inhalation sedation is the most commonly used, accounting for 45.9% in 2002, but increased to 89.5% in 2015. Combination of nitrous oxide inhalation sedation, chloralhydrate and hydroxyzine was the most common, accounting for 5.7% in 2002, but decreased to 2.9% in 2015.
There is a trend to use the sedation method more safely and in a way that reduces side effects.
