Dental professionals are exposed to various occupational risks, among which the problem of hearing damage has been newly revealed. There have been some researches reporting that noise occurring in a dental office exceeds the Occupational Safety and Health Act (OSHA) Standards. Especially, the pediatric dentists are repeatedly exposed to an additional noise source called the crying sound of children in addition to all kinds of noises from dental instruments. Accordingly, this study intended to investigate the noise environment likely to affect pediatric dentists and to examine the possibility of resultant hearing damages. The level of noise was measured respectively, when various dental instruments (ultrasonic scaler, high-speed handpiece, low-speed handpiece) are operated, when children are crying, and when both occasions take place simultaneously (from the distance of 30 cm) with a portable noise meter. And the daily duration of pediatric dentists exposed to the noise environment was surveyed. The results were compared with the standard value of noise threshold of NIOSH, OSHA, and that of hearing damage of CRA News letter respectively. Considering the intensity and exposure time, the noise environment of pediatric dentists exceeds the allowable noise threshold values. Even only one exposure to crying child was likely to lead to permanent hearing damage. Comparatively, pediatric dentists have a higher risk for occupational hearing damages, and some active measures are thought highly desirable to minimize it.

The purpose of this study was to investigate current status of sedation training for the residents in pediatric dentistry training institutions and opinions about continuing education after the residency program. Surveys were sent to 18 pediatric dentistry training institutions by e-mail, and the responses were collected and analyzed. Most of the sedation education period for the residents were the 1st-year education (61.1%) and 1 - 3 years of integrated education (55.6%). In terms of an externship, 5 institutions (27.8%) sent their residents to the department of anesthesiology. Second half of the 1st year (50%) was the highest for a resident to use sedation for the first time. The period of supervisor participation varied from not participating at all to whole time throughout the residency program. The sedation training is conducted at all training institutions, but there were variations in the experience that a resident can gain. All training institutions agreed on the necessity of continuing education of the sedation, but there were various opinions regarding time, method, and the period of review course. Overall, this study suggested that continuing education should be consisted of 1 - 2 hours of didactic education every year and clinical skills and simulation training in every 2 - 3 years.

근래 환자의 불안을 조절하는 것이 성공적인 치료에 매우 중요하다는 인식이 확산되면서 의과, 치과, 영상의학과, 응급실 및 외래 수술센터 등에서 진정요법에 대한 필요가 현저하게 늘어났다. 응급상황이거나 아니거나 진정요법의 필요성은 점차 증가하고 있고 대한 소아치과학회는 이러한 진정요법에 대한 지침을 출간한 바 있다. 이번 개정은 진정요법에 필요한 적절한 환자감시(monitoring)의 필요에 관한 최신지견을 반영한 것이나 그럼에도 불구하고 이 지침에 충실하였다고 해서 특정환자의 결과를 보장하지는 못한다. 그러 나 이번에 소개하는 진정요법 protocol은 널리 받아들여지는 것으로 부작용 역시 최소화한 것이다. 소아 환자의 진정요법은 원하는 수준의 진정이나 투여 방법과는 상관없이 호흡기능 저하와 환자의 방어 반응이 소실될 수도 있다는 인식하에 작성되었다. 이번 호에서는 최근 2006년에 미국소아과학회와 미국소아치과학회가 공동으로 개정된 지침(Guideline for Monitoring and Management of Pediatric Patients During and After Sedation for Diagnostic and Therapeutic Procedures developed and endorsed by AAP a and AAPD)이 어떻게 변경되는지에 중점적으로 알아보며 새로 변경된 지침에 따라 소아치과의의 진정요 법의 진료와 교육도 영향을 미칠 것이다. 이러한 영향으로 다양한 약 투여방법(Alternative routes of d drug administration)과 다양한 약물의 선택에 대해 알아 보기로 한다.

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is an X-linked recessive disorder and is the most common enzyme deficiency worldwide. Although this disease is rare in Korea, its prevalence may increase due to an increase of multicultural families. Patients with this deficiency are prone to hemolytic anemia provoked by specific drugs commonly used or prescribed in pediatric dentistry. It is necessary for pediatric dentists to have accurate knowledge of a patient's medical history and to consult with a pediatric hematologist to avoid oxidative stress that can lead to hemolysis. The most effective treatment is prevention of exposure to factors that may trigger anemia. Appropriate education regarding risk factors is essential for patients diagnosed with this disease. This case report aimed to discuss the drugs and dental management methods that should be cautious in children with G6PD deficiency.

The purpose of this study was to compare factors causing stress in pediatric and general dentists when treating pediatric patients and to evaluate their overall occupational stress level. A total of 191 dentists participated in the online survey, consisting of 66 pediatric dentists and 125 general dentists. The questionnaire was conducted using Google Form. Both groups were stressed due to poor cooperation of patient and caregiver, uncertain prognosis of treatment, and low cost of pediatric dental treatment. The pediatric dentists felt relatively high stress due to poor cooperation from caregivers and an uncertain prognosis of treatment (p < 0.05). Overall occupational stress was high in both groups in the order of patient, time, job environment, and income-related stress, and the degrees of pediatric dentists were lower than general dentists. Among the 3 sub-factors of occupational burnout, more than 98% of both groups showed burnout in "depersonalization", and more than 69% of both groups showed burnout in "emotional exhaustion". Both groups showed a low burnout rate in "reduced sense of accomplishment" and pediatric dentists showed a higher sense of accomplishment than general dentists (p < 0.05). This study showed that both groups were under high occupational stress due to various factors, and efforts were required to relieve stress.

This study aimed to evaluate the effects of two ginsenoside Rb1 (G-Rb1) loaded films on oral wound healing. Two types of G-Rb1 films, G-Rb1 loaded carboxymethyl cellulose (GCMC) film and G-Rb1 loaded hyaluronic acid (GHA) film, were developed. A total of 36 Sprague-Dawley rats were divided into 3 groups: control, GCMC, and GHA. After wound formation on midpalate, the control group was left without treatment, whereas the experimental groups had films attached. The specimen was analyzed clinically and histologically after 7 and 21 days. For clinical analysis, the area of incompletely re-epithelialized wound was measured. For histological analysis, the distance between the margins of the wound (soft tissue gap) was measured and the percentage of the collagen-stained area on the specimen was calculated. In clinical and soft tissue gap analysis, the GCMC group presented improved healing compared to the GHA group and the control at day 7 (p < 0.05). And, both GCMC (9.74 ± 10.12%) and GHA groups (19.50 ± 14.47%) presented greater collagen-positive pixels compared to control (0.89 ± 1.60%) at day 7 (p < 0.05). However, there were no differences in these parameters among the groups on day 21. Therefore, G-Rb1 loaded films improved oral wound healing.

This study aimed to investigate a quantitative analysis of the anatomical characteristics of the maxillary supernumerary lateral incisor and its relationship with lateral incisors. Forty-four supernumerary lateral incisors from 43 patients were evaluated for analyzing the position, shape, direction, and relationship between the supernumerary lateral incisor and the normal lateral incisors, using cone-beam computed tomography (CBCT). To compare the size of crown, the mesio-distal width was measured and the Nolla stage was used for evaluating the degree of root development to compare tooth maturity. The supernumerary lateral incisors were in the normal direction at a rate of 90.9%, and in a supplemental shape at a rate of 84.1%. The supernumerary lateral incisor was smaller in size compared to the adjacent lateral incisor and opposite lateral incisor (p < .0001). There was no statistically significant difference in the development stage of root. Based on these results, the supernumerary lateral incisor is similar with the lateral incisor, but has a difference in the size of crown. It is necessary to distinguish the supernumerary lateral incisor from the lateral incisor precisely to reduce clinical complications.

This study aimed to analyze the preoperative factors of immature first molars treated with vital pulp therapy and to find out their correlation in pediatric patients. From May 2014 to January 2020, 523 patients and 1,242 immature first molars were investigated. Factors including age, sex, tooth location, Molar-incisor hypomineralization (MIH), caries cavity location, and history of previous restoration were evaluated. As a result of the study, the vital pulp therapy group had 5.56 times more MIH, 3.39 times more mesial cavities, and 8.73 times more distal cavities. In order to avoid vital pulp therapy in immature first molar, early diagnosis and active management of MIH and preventive treatment of mesial and distal caries are necessary after its immediate eruption.

The purpose of this retrospective study was to evaluate the survival rate by comparing Class II restoration using flowable resin composite with stainless steel crown in primary molars. Electronic medical records and radiographs of 1,504 primary molars with proximal caries of 590 patients from June 2015 to August 2019 were analyzed. With the collected data, survival analysis was performed using the Kaplan-Meier method. The 1-year survival rate of flowable resin composite in the primary molar was 98.5%, 3-year survival rate was 87.7%, and mean survival time was 39 months. There was no statistically significant difference between flowable resin composite and stainless steel crown (p = 0.896). Within the limits of this study, Class II restoration using flowable resin composite can be considered a promising option for the treatment of proximal caries in primary molars.
