This study aims to investigate changes in dental service use among pediatric patients during the COVID-19 pandemic. The analysis was performed by collecting information about the number of visits, age, gender, diagnoses, and treatments for patients at the Pediatric Dentistry Department of Seoul National University Dental Hospital from January 2017 to December 2022. Compared with the period from 2017 to 2019, the total number of visits decreased during the COVID-19 pandemic, with a substantial decline in 2020. Patients in all age groups, except those aged 10 - 14, experienced decreased visits, and there was no significant gender difference. Z29.8 (need for other specified prophylactic measures) declined in all age groups, especially among those aged 0 - 4, except for those 20 years and older. K02.1 (caries of dentine) was sought by the age groups in the following order: 10 - 14, 15 - 19, 5 - 9, and 0 - 4 years, with the most significant decrease in the 0 - 4 years age group compared to others. K07.4 (malocclusion, unspecified) decreased in younger groups aged 9 and below but increased in older groups aged 10 and above. During the period from 2020 to 2022, preventive, restorative, pulp, and trauma treatments decreased, but surgical and orthodontic treatments increased compared with the previous three years. The use of sedation decreased and general anesthesia increased during COVID-19 compared to pre-pandemic. This study describes the impact of the COVID-19 pandemic on pediatric dentistry, making it a valuable reference for future pandemics.

This study aimed to assess the competency of artificial intelligence (AI) in pediatric dentistry and compare it with that of dentists. We used open-source data obtained from the Korea Health Personnel Licensing Examination Institute. A total of 32 item multiple-choice pediatric dentistry exam questions were included. Two AI-based chatbots (ChatGPT 3.5 and Gemini) were evaluated. Each chatbot received the same questions seven times in separate chat sessions initiated on April 25, 2024. The accuracy was assessed by measuring the percentage of correct answers, and consistency was evaluated using Cronbach's alpha coefficient. Both ChatGPT 3.5 and Gemini demonstrated similar accuracy, with no significant differences observed between them. However, neither chatbot achieved the minimum passing score set by the Pediatric Dentistry National Examination. However, both chatbots exhibited acceptable consistency in their responses. Within the limits of this study, both AI-based chatbots did not sufficiently answer the pediatric dentistry exam questions. This finding suggests that pediatric dentists should be aware of the advantages and limitations of this new tool and effectively utilize it to promote patient health.

This research aimed to evaluate the outcomes of autotransplantation in both children and adolescents, with a focus on root growth, and determine the clinical and radiographic factors associated with the success rate. In this study, 73 teeth, autogenously transplanted in 63 patients, were examined over an observation period of 3.2 years on average. The mean age at the time of autotransplantation was 11.9 years. Based on the radiographic criteria, the success rate was 73.97% and the survival rate was 100%. Based on the radiographic criteria, the success rate was 73.97%, and the survival rate was 100%. A significant increase in root length was observed in the transplanted teeth with an open apex. An association was found between the success rate and use of bone graft and surgeon experience. In conclusion, greater clinical experience in autotransplantation (> 36 cases) and prohibiting the use of bone grafts may improve the prognosis of the transplanted teeth in children and adolescents.

1956년 한국에 처음 소아치과학교실이 창설되었고, 1992년 한국 최초의 소아전문 치과의원이 등장하였다. 치의학의 발전과 소아치과에 대한 대중의 인식 변화로 인해 소아전문 치과의원은 점점 더 증가하고 있다. 이 연구의 목적은 지역 분포를 포함한 여러 측면에서 한국의 소아전문 치과의원의 현황을 조사하는 것이다. 한국에 17,917개의 치과의원 중 소아전문 치과의원은 343개이고, 1.91%를 차지하였다. 343명의 소아전문 치과의원 개원의 중 248명이 소아치과 전문의였다. 소아치과 전문의 248명 중 25명이 전문의를 표방하여 개원하고 있었다. 16개의 시도 중 경기도에 소아전문 치과의원이 가장 많았고, 33.5%를 차지하였다. 서울과 부산이 그 뒤를 이었다. 서울의 25개 구 중에서는 강남구에 소아전문 치과의원이 가장 많았고, 유소년 10만명당 소아전문 치과의원 수도 강남구에서 제일 높았다. 소아전문 치과의원의 90.9%는 평일 야간진료를 하지 않았고, 26.5%는 토요일에 15시 이후에 문을 닫았다.

Impaction of the tooth can cause functional and esthetic problems, so early intervention is critical. This report describes two cases of orthodontic traction of impacted mandibular canine and mandibular premolar teeth using a modified mandibular lingual arch soldered with traction hooks rather than a conventional orthodontic appliance. By planning the position and shape of the traction hooks with consideration for the three-dimensional position and angulation of the impacted teeth, clinicians can apply the intended direction and magnitude of traction force. Furthermore, this appliance can be used for multiple impacted teeth in various locations within the mandibular arch by modifying the position and shape of the traction hooks.

The high success rate of dental treatment is dependent on the cooperation of pediatric patients during procedures. Dental treatment often causes pain, particularly in children. The factors in providing treatment to pediatric patients include the characteristics and location of the tooth, profoundness of the anesthesia including the type of local anesthetic, and cooperation of the patient. Previous studies have examined several techniques to successfully achieve profound pulpal anesthesia in maxillary permanent teeth. The dentist should select the injection technique to be used based on patient needs. In children, either buccal with palatal injections or buccal with intra-septal injections may be used to anesthetize the permanent maxillary first molar. Buccal with palatal injections are commonly used prior to routine maxillary dental procedures. Currently, there are only a few studies on the employment of buccal with intra-septal injections to anesthetize permanent maxillary first molars in pediatric patients. This review will focus on efficacy of buccal with palatal versus buccal with intra-septal pulpal anesthesia of the permanent maxillary first molars in pediatric patients and aim to determine which technique should be used during routine dental procedures.

In clinical pediatric dentistry, a base material with optical properties, including transparency, that can mask the color of the material used for root canal-filling is preferred. This study aimed to examine the optical properties of various base materials by thickness. The disk-shaped specimens were photopolymerized and fabricated using Ionosit (IN), TheraCal LC (TL), TheraCal PT (PT), and A2 shade of Filtek^TM Supreme Flowable Restorative (FZ), Fuji II LC (FL), and Ketac^TM Fil (KF) with 1 and 2 mm thickness. The color parameters of these specimens were measured using a spectrophotometer on a black and white background and were measured using the same method on a mold containing Vitapex^® and gutta-percha. The translucency parameter (TP) and color difference were calculated for each group. The Kruskal-Wallis and Bonferroni tests were used in the statistical analyses. The TP decreased when the thickness was 2 mm compared with 1 mm. The TP values of TL and PT were the lowest at all thicknesses. The TP values of 2 mm thickness in all molds filled with Vitapex^® and gutta-percha were the lowest for TL, PT, KF, and IN. In TL and PT, the color difference before and after the application of the canal-filling material was the smallest, regardless of material thickness. Within the limits of this in vitro study, TL, PT, KF, and IN demonstrated better masking of the color of canal-filling material.

Early loss of the primary maxillary second molar can lead to complications in which mesial drift of the adjacent first molar (M1) can disturb eruption of the succedaneous second premolar (P2). This study reports two cases of space loss for P2 caused by early exfoliation of its predecessor. After the eruption of the first premolar, the Jones jig appliance was used to distalize M1 and regain space for the eruption of P2. The appliance was further utilized to align the palatally erupted P2 into the dental arch. In both cases, the space and corrected position of P2 were well maintained. Early exfoliation of the primary second molar caused by mesial encroachment of M1 is a common phenomenon, and pediatric dentists should attend to this during routine examinations. An appropriate intervention should be initiated when the primary second molar is lost during the mixed dentition period. If used with careful anchorage control, the Jones jig appliance can effectively resolve this problem.
