Utilising blood-derived products for guided tissue regeneration in periradicular surgery: a systematic review and meta-analysis

ORCID

Abstract

BackgroundSince 1982, guided tissue regeneration (GTR) has become increasingly popular. The recent progress in GTR research focuses on the application of blood-derived products. However, no comprehensive systematic review has been conducted to assess its effectiveness specifically in periradicular surgery. Therefore, the aim of this review was to analyse the outcomes of root-end surgery compared to periapical surgery incorporating GTR using blood-derived products.MethodsThis review involved randomised controlled trials exploring the comparison between GTR utilising blood-derived products and the conventional periapical surgery. The databases Embase, MEDLINE, Cochrane CENTRAL, and Dentistry and Oral Sciences Source were searched, with the most recent search conducted on December 16th, 2022. Additionally, reference lists of similar systematic reviews were examined, while international trials registries and repositories were consulted for unpublished studies. Two blinded independent reviewers carried out the screening and the included studies underwent critical appraisal. The findings are reported in accordance with the PRISMA guidelines.ResultsA total of 261 publications were initially reviewed based on their title and abstract, resulting in seventeen studies that underwent full-text screening. At this stage, 14 studies were excluded, leaving three randomised controlled trials to be included. These trials involved a combined total of 85 patients. A meta-analysis was conducted for the outcome of healing. The overall treatment effect was 0.78 (95% CI 0.18 to 3.34), indicating a preference towards the control group.ConclusionBased on a meta-analysis of three studies, there was no statistically significant distinction observed in terms of healing between the GTR involving blood-derived products and standard procedure groups. However, critical appraisal revealed indirectness and imprecision, resulting in a certainty rating of 'low'. Thus, additional robust evidence is necessary to support the utilisation of blood-derived products in GTR techniques to enhance periradicular surgery outcomes.Systematic review registration numberPROSPERO CRD42020222663.
