[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).

Immediate implants show good therapeutic and aesthetic effect in patients with class III and IV bone loss of the anterior teeth.

Objective: To study the effect of immediate implantation on the restoration effect and aesthetic indicators in patients with class III and IV bone loss of the anterior teeth.

Methods: This retrospective study collected the data of 82 patients with single loss of anterior teeth who received tooth implantation. According to the treatment methods, these patients were divided into an observation group (N=43) and a control group (N=39).

[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.
