[Construction and evaluation of the regional Children's oral health network platform].

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.

[Evaluation of the effect of MTF-S on the removal of impacted mandibular wisdom teeth with complete or partial crown impaction].

Purpose: To evaluation the effect of modified triangular flap-secondary healing (MTF-S) on the treatment of mandibular impacted wisdom teeth with full or partial bone impaction.

Methods: A total of 207 patients with mandibular impacted wisdom teeth were selected in Shaoxing Stomatological Hospital from June 2022 to June 2023. Among them, 86 patients had completely impacted wisdom teeth (group A), and 121 patients had partially impacted wisdom teeth (group B).

[The role of Wnt5b in the promotion of osteogenic differentiation by puerarin].

Purpose: To investigate the capability of puerarin on osteogenic induction in bone marrow-mesenchymal stem cells (BMMSCs), and to explore the mechanism of osteoinductivity of puerarin in vitro.

Methods: After segregating and cultivation, bone marrow stromal cells from 3-weeks SD rats were induced by osteogenesis medium containing different concentrations of puerarin in induction groups; while in non-induction group, BMMSCs were still cultured with DMEM medium. Following continued culture for 2-4 weeks, alkaline phosphatase activity, osteocalcin and Wnt5b were measured.

[Fixed orthodontic treatment combined with surgical fenestration in the treatment of impacted mandibular first molars].

Purpose: To investigate the treatment of impacted mandibular first molars by straight wire appliance technique, and evaluate the effectiveness of treatment.

Methods: Eight patients with first mandibular impacted molars were treated with MBT straight wire appliance. Surgical fenestration was done after sufficient space created.
