[Evaluation of the efficacy of iRoot BP Plus combined with Nd:YAG laser in the treatment of cariogenic pulp exposure].

PURPOSE: To evaluate the pulp capping effect of iRoot BP Plus combined with Nd: YAG laser irradiation in the treatment of caries induced exposed pulp and its impact on pulp vitality and occlusal function recovery.

METHODS

From January 2022 to January 2023, a total of 196 patients with dental caries and exposed pulp, including 268 permanent teeth, were selected and randomly divided into the experimental group of 98 patients (136 teeth) and control group of 98 patients (132 teeth) using computer randomization. Both groups were treated with Nd:YAG laser after cleaning the caries. The experimental group was filled with iRoot BP Plus and the control group was filled with mineral trioxide polymer (MTA). The treatment efficacy, pulp vitality and occlusal function were compared between the two groups. SPSS 24.0 software package was used for statistical analysis of the data.

RESULTS

There was no significant difference in the success rate of treatment between the two groups at 3, 6 and 12 months after surgery(P＞0.05). At 12 months after treatment, the bite force and chewing efficiency of the experimental group were significantly higher than those of the control group(P＜0.05). At 3, 6 and 12 months after treatment, the pulp vitality and pulp blood flow in both groups significantly decreased compared to preoperative levels (P＜0.05); the pulp vitality and pulp blood flow of the experimental group were significantly higher than those of the control group(P＜0.05).

CONCLUSIONS

iRoot BP Plus combined with Nd: YAG laser in the treatment of cariogenic exposed pulp is helpful to preserve pulp vitality and improve occlusal function.
