Optical Coherence Tomography for Detection of Dental Cracks and Vertical Root Fracture: A Scoping Review.
Article in Clinical and experimental dental research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesVertical root fractures (VRFs) pose significant clinical challenges and may result in tooth loss. Current diagnostic methods, including conventional radiography and CBCT, are challenging to detect VRFs, especially in the early stages. Optical coherence tomography (OCT) has recently been introduced as a non-invasive imaging technique for dental diagnostics. However, current knowledge of OCT in endodontics requires further research. This Article will review current literature on OCT and evaluate its potential as a diagnostic tool for VRFs in endodontics.
methodsA comprehensive scoping review was conducted using electronic databases including PubMed, Scopus, Ebsco, Google Scholars, and Embase without any language restrictions up to January 2025, focusing on OCT applications in diagnosing cracks and VRFs. Google and Open-Grey were used to search for grey literature alongside handsearching. Clinical and laboratory-based studies conducted on adult human-teeth were considered eligible. A total of 28,303 studies were generated when screened in the last 20 years; 27,887 studies were found relevant, and 416 duplicates were removed. Following title and abstract screening, a total of 36 studies were considered for full-text review. Ten studies met the inclusion criteria and were included in this review.
resultsOCT system demonstrated high specificity (63%-100%) and sensitivity (83%-98%) in detecting cracks and VRFs. SS-OCT demonstrated promising imaging capabilities and deep penetration. OCT offers advantages over radiographs and CBCT in non-radiation exposure and real-time imaging. OCT systems could be considered in clinical practice following improvements in relation to penetration depth and intra-oral adaptation.
conclusionsWithin the limitation of this scoping review, the use of OCT is promising for detection of cracks and VRFs. By addressing the limitations related to penetration depth, mechanical design, and soft tissue imaging, OCT may find its path into clinical adoption, including endodontics. Areas that can help includes developing OCT systems tailored for routine endodontic use and assessing long-term impacts in the field.
