Summary:In order to achieve accurate and minimally invasive root canal treatment and enhance the fracture resistance of tooth tissue after root canal therapy, this study explores digital guided mediated minimally invasive root canal treatment and compares it with conventional root canal treatment to provide a more favorable method for clinical practice. Forty freshly extracted first permanent molars were randomly divided into control group and experimental group. Teeth in the control group were treated with conventional root canal treatment, while teeth in the experimental group were treated with precise minimally invasive root canal treatment. The difference between the time of opening of the pulp chamber and the area of the open pores on the total area of the occlusal surface was compared. Loading test was carried out on the subjects using a universal testing machine, and the fracture resistence of the tooth tissues of the two groups were measured. Statistical analysis was performed using SPSS 24.0 software package
