Abstract Objective: To analyze the value of different pastes in pulp revascularization in the treatment of patients with necrotic pulpitis of young permanent teeth. Methods: A total of 92 patients with necrotic pulpitis of young permanent teeth admitted to our hospital from January 2019 to February 2020 were selected as the research subjects. They were randomly divided into control group (46 cases, 46 affected teeth) and observation group (46 cases, 46 affected teeth) by simple random grouping. Both groups were treated with pulp revascularization, the control group was treated with triple antibiotic paste, and the observation group was treated with calcium hydroxide paste. Both groups were followed up for 12 months after completion of treatment. Clinical efficacy, positive rate of bacteria after sealing, follow-up and incidence of adverse reactions during follow-up were counted in two groups 1 month after treatment. The scores of clinical symptom before treatment and 1 month after treatment, and scores of visual analogue scale (VAS) before treatment and 3, 6 and 12 months after treatment were compared between two groups. Results: The total effective rate at 1 month after treatment of observation group was 93.48%, which was significantly higher than control group at 78.26% (P<0.05). Compared with before treatment, the scores of gingival swelling, pain and tooth loosening in the two groups decreased 1 month after treatment, and gingival swelling, pain and tooth loosening scores decreased more significantly in the observation group than in the control group (P<0.05). When comparing VAS scores between the two groups, they were higher at 3, 6 and 12 months post-treatment than pre-treatment, 6 and 12 months post-treatment than 3 months post-treatment and 12 months post-treatment than 6 months post-treatment (p<0.05). 12 months after treatment, the score of VAS of observation group was lower than that of control group (P<0.05). After sealing, the positive rate of bacteria in the observation group was lower than the control group (P<0.05). During follow-up, there was no significant difference in the incidence of crown discoloration and total adverse reactions (0.00% and 4.35%, 4.35% and 10.87%) between the the observation group and the control group (P>0.05). Conclusion: The use of calcium hydroxide paste can effectively reduce the rate of bacterial positivity and post-treatment pain in patients with necrotic pulpitis in young permanent teeth, and improve the clinical symptoms of patients with better treatment effect and safety.
