Does Sickle Cell Anaemia Have a Relationship With Avascular Pulp Necrosis? A Systematic Review.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This systematic review examined the relationship between sickle cell disease (SCD), an inherited genetic hemoglobinopathy, and avascular pulp necrosis (APN) in intact teeth. A comprehensive search of eight electronic databases was performed up to December 2024. Eligible studies included observational or interventional designs reporting APN in intact teeth of individuals with SCD. Risk of bias was assessed with the Joanna Briggs Institute Critical Appraisal Checklists, and certainty of evidence with GRADE. The search retrieved 407 records; four observational studies (two cohort and two case-control) met inclusion criteria, comprising 311 individuals with sickle cell anaemia (SCA). There is a relationship between SCA and APN. However, all included studies presented a risk of bias of 30% or higher, and the certainty of evidence was rated very low. These results provide weak scientific support for the association between APN and SCA, underscoring methodological limitations in the current dental literature.
