Pulpitis is an inflammatory response of the pulp tissue triggered by bacterial infection or mechanical trauma. Current diagnostic criteria classify it into two categories: reversible pulpitis and irreversible pulpitis. Wolters et al. proposed a four-level classification of pulpitis based on clinical symptoms, establishing a guiding framework for minimally invasive endodontics. With the development of precision medicine and molecular biological diagnostic techniques, biomarker detection has emerged as a quantitative tool for determining endodontic status. Diagnostic techniques that integrate multimodal information such as pain intensity assessment, endodontic diagnostic testing and biomarker detection can break through the limitations of traditional or single diagnostic methods, which not only providing clinicians with more scientific and comprehensive ideas for endodontic status assessment and treatment decision options, but also promoting the transition to precision medicine for endodontic diagnosis.

Objective:To explore the mediating role of family cohesion between family expressiveness and preschool children's behavior.Methods:Using the method of stratified cluster random sampling, the parents of 1 213 children in Shenzhen kindergartens were assessed by the Achenbach child behavior checklist (parent questionnaire) (CBCL, 4-16 years) and family environment scale-Chinese version (FES-CV). After the survey, SPSS 24.0 was used to conduct the data analysis and the Bootstrap method was used to test the mediation effect.Results:(1)The total score of children's behavior 147.0(135.0, 163.0) was found to be significantly negatively correlated with family expressiveness score 6.0 (5.0, 7.0) and family cohesion score 8.0 (6.0, 9.0), and the correlation coefficients were -0.145 and -0.187(both P<0.01). (2) Family expressiveness score was positively related to family cohesion score ( r=0.443, P<0.01). (3)The direct effect of family expressiveness on children's behavior was -0.072, and the 95% confidence interval was (-0.133, -0.010). Family cohesion had a mediating effect between family expressiveness and children's behavior, 95% confidence interval was (-0.129, -0.058), and the mediating effect accounted for 56.4% of the total effect. Conclusion:Family cohesion plays a partial mediating role between family expressiveness and children's behavior.
