This study aimed to develop a deep-learning model for bone age estimation using lateral cephalometric radiographs (LCRs) and regions of interest (ROIs) in growing children and evaluate its performance. This retrospective study included 1050 patients aged 4-18 years who underwent LCR and hand-wrist radiography on the same day at Pusan National University Dental Hospital and Ulsan University Hospital between January 2014 and June 2023. Two pretrained convolutional neural networks, InceptionResNet-v2 and NasNet-Large, were employed to develop a deep-learning model for bone age estimation. The LCRs and ROIs, which were designated as the cervical vertebrae areas, were labeled according to the patient's bone age. Bone age was collected from the same patient's hand-wrist radiograph. Deep-learning models trained with five-fold cross-validation were tested using internal and external validations. The LCR-trained model outperformed the ROI-trained models. In addition, visualization of each deep learning model using the gradient-weighted regression activation mapping technique revealed a difference in focus in bone age estimation.

This systematic review examined the effectiveness of game-based teaching methods on the oral health of children (4-12 yrs). Scopus, Medline and Web of Science databases were searched according to specific inclusion and exclusion criteria. Inclusion criteria included randomised trials that compared traditional methods of oral health education with game-based interventions in preschoolers and school-age children. The quality of the data was determined using Cochrane risk-of-bias tool for randomized trials (ROB-2). A total of seven studies that examined 1097 children (4-12 yrs) were included in this systematic review with the association of game-based teaching of oral health. The findings indicated that the utilization of game-based methods significantly improved children's oral health outcomes when compared to traditional teaching approaches. Specifically, the game-based interventions demonstrated positive effects on various aspects of oral health, including enhanced oral health knowledge, improved oral hygiene scores, and reductions in debris and plaque scores. The game-based interventions were found to be more effective in promoting oral health when compared to conventional methods of teaching, such as verbal instructions or educational posters. Based on the limited evidence available, game-based teaching appears to be an effective approach for promoting oral health among children, consistently demonstrating positive outcomes, including improved oral health knowledge, enhanced oral hygiene scores, and reductions in debris and plaque scores.

The scoping review included 19 relevant studies. In most of the studies included, the status of oral health of children is linked to the caregiver's oral health literacy. Children of caregivers with low oral health literacy were found to exhibit deleterious oral health habits, including inadequate teeth brushing and the use of bottles at night-time. Dental caries was found to be more common in children whose parents had low oral health literacy. Striving for optimal oral health literacy in the community is a valuable and worthwhile effort.
