Purpose: To explore a more effective comprehensive prevention and treatment model for children's oral health by constructing a health network platform that integrates medical information evaluation, interaction, monitoring, and prevention with oral health management as the core., Methods: The database of Shaoxing Children's Oral Health Management Network Platform was established. The oral health survey and information entry of 7 042 second-grade children in primary school in Yuecheng District from 2021 to 2022 were conducted. An open randomized controlled clinical trial was designed, with 3 472 of 7 042 children randomly assigned to the platform management group and 3 570 to the control group. One year later, oral examinations were conducted again on two groups of children, and the correlation between oral examination indicators between the two groups was statistically analyzed using SPSS 25.0 software package., Results: There was significant difference between the two groups in the mean number of newly added deciduous caries decayed- missing-filled teeth(dmft), deciduous caries decayed teeth (dt), deciduous caries missing teeth(mt), and deciduous caries filled teeth(ft) after one year(P＜0.05). The newly added rates of caries, gingival bleeding, calculus detection, and malocclusion between the two groups were lower in the platform group than in the control group, with a significant difference(P＜0.05)., Conclusions: To the prevention and treatment of oral diseases, intelligence has become more and more indispensable and important. Building a network platform for oral health is an effective way to promote oral health level.

Background: There is a general consensus among dental professionals regarding the extraction of impacted third molars in the presence of clinical symptoms. However, there is less agreement on the management of asymptomatic third molars. The objective of this study is to compare the perspectives of oral surgeons and orthodontists regarding the indications for the extraction of asymptomatic third molars. It is possible that healthcare professionals from different specialties may approach the extraction of these teeth in different ways., Methods: In this cross-sectional study, a web-based questionnaire has been employed to collect data by inquiring about the reasons why participants prefer the extraction of asymptomatic third molars. Descriptive statistics were employed to evaluate the data obtained. The level of significance was set at P < 0.05., Results: Prophylactic extraction of partially impacted molars was more favored among the participants (P < 0.05). The orthodontists preferred prophylactic extraction due to the risk of late anterior dental crowding (LADC); however, the oral surgeons preferred pre-pregnancy extractions (P < 0.05). The extraction decision for partial impaction was higher in females when the risk of distal caries was considered. For fully impacted ones, it was higher in males when the risk of caries and pericoronitis were considered (P < 0.05)., Conclusions: Orthodontists preferred extraction because of the risk of LADC and caries, while oral surgeons focused on preventing pericoronitis, pathology, focal infection, and symptoms during pregnancy. This divergence between the participants may inform the guidelines for prophylactic management of third molars. These findings may be pertinent in gender medicine., Clinical Relevance: This study has been enlightening for departments to consult each other before the extraction of a patient's asymptomatic third molar., (© 2024.

Objective: To investigate the effect of sequential distalization on increasing gaps in the maxillary anterior teeth, focusing on the control of torque and three-dimensional teeth movement during anterior retraction with clear aligners in extraction cases., Methods: We recruited 24 patients who were undergoing extraction bilateral maxillary first premolars with clear aligners. According to a predetermined increment in the spaces between the maxillary anterior teeth, the patients were divided into three groups: those with no gap (9 cases), a 0.5 mm gap (6 cases) and a 1.0 mm gap (9 cases). In each group, a 2.0 mm en-mass retraction was applied on the anterior teeth. Plaster casts of the upper full dentition were obtained both before and after a 2 mm retraction. The palatal folds were used to overlap each pair of models. The three-dimensional movement of the teeth and the change of torque for the anterior teeth were subsequently analyzed using Geomagic Studio 2014 software., Results: The change in torque in the groups with added gaps was significantly smaller than that in the group with no gaps (P < 0.05). There was no significant difference in this respect when comparing the group with a 0.5 mm gap added to the group with a 1.0 mm gap was added (P > 0.05). In the labial-lingual and vertical directions, the displacements of the central and lateral incisors were smaller in the groups with additional gaps compared to those in the groups without gaps (P < 0.05). However, there was no significant difference observed when comparing the group with a 0.5 mm added gap to the group with a 1.0 mm added gap (P > 0.05). Then, a comparison was made between the displacement of the second premolar to the second molar in the mesial-distal direction across all groups. The study revealed that the anchorage molars in the group without gaps demonstrated significantly smaller displacement compared to those in the group with additional gaps (P < 0.05)., Conclusion: Advantages were observed in controlling the torque of the anterior teeth and achieving a desired pattern closer to normal bodily movement by sequentially distalizing the maxillary anterior teeth gaps. Increasing the gaps between the maxillary anterior teeth also resulted in improved control of the vertical direction of the anterior teeth. However, this retraction strategy necessitates substantial protection of the anchorage molars., (© 2024. The Author(s).)
