Vital Pulp Therapy in Teeth with Symptomatic Irreversible Pulpitis: A Systematic Review.

Abstract

Purpose: Nonsurgical root canal therapy (NSRCT) is indicated for management of permanent teeth diagnosed with symptomatic irreversible pulpitis. However, recent research has suggested that vital pulp therapy (VPT) may be a less invasive option in these cases. The purpose of this systematic review was to evaluate the outcomes of VPT, using hydraulic calcium silicate cements (HCSCs) including complete and partial pulpotomies in permanent posterior teeth with symptomatic irreversible pulpitis.

Materials and methods: The PRISMA recommendations were adhered to. The search approach used electronic databases from PubMed, EMBASE, the Cochrane Library, and grey literature. The Newcastle-Ottawa Scale, ROBINS-I, and Cochrane Collaboration Risk of Bias tools were used to evaluate the quality of the selected studies.

Results: The initial database search turned up 142 papers, of which 3 prospective cohort studies and 9 randomised controlled trials were selected for analysis. For three, seven, and two articles, the risk of bias was rated as 'high' or 'serious,' 'fair,' and 'low,' respectively. The success rates for VPT using HCSCs typically ranged from 78% to 90% one to five years following VPT. The results of the VPT and NSRCT were equivalent at one and five years, according to two articles. Although the intra-operative pulp assessment is essential for VPT treatments, most studies did not provide a thorough account of this process or the time required to achieve haemostasis. Three studies reported sample sizes that were 23 teeth. The 12 studies that were analysed revealed successful VPT procedures using HCSCs in permanent posterior teeth that had symptomatic irreversible pulpitis, with radiographic success rates ranging from 81% to 90%. Two articles claimed that the results of VPT and root canal therapy were equivalent.

Conclusion: When considering VPT as an alternative to NSRCT, appropriate case selection and outcome criteria must be created. This data highlights the need for additional studies contrasting the longer-term effects of different treatment regimens.
