Association between orocraniofacial trauma and dental injuries: A systematic review and meta-analysis.
Synthesis in International journal of legal medicine, 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
backgroundOrocraniofacial (OCF) trauma includes injuries to the oral cavity, cranial structures, and facial skeleton caused by road traffic accidents, interpersonal violence, falls, and other high-energy events. Dental injuries are an often underreported component of OCF trauma despite their important forensic value in victim identification, documentation of violence, and determination of cause of death.
methodsThis systematic review and meta-analysis was conducted in accordance with the PRISMA 2020 guidelines. Five electronic databases (PubMed, Scopus, Web of Science, ProQuest, and Cochrane Library) were searched from inception to March 2026 without language restrictions. Risk of bias was assessed using the Newcastle-Ottawa Scale (NOS) and Risk of Bias 2 (RoB-2) tools. A random-effects meta-analysis was applied, and heterogeneity was quantified using the I² statistic.
resultsOut of 1,860 records, 18 studies involving 46,247 participants across 12 countries met the inclusion criteria. The pooled prevalence of dental injuries in OCF trauma was 24.3% (95% CI: 19.8-29.1%), with substantial heterogeneity (I² = 81.2%). Crown fractures were the most common injury type (OR 2.09; 95% CI: 1.74-2.51). Interpersonal violence showed the strongest association (OR 2.61; 95% CI: 1.98-3.44). Male gender (OR 1.58) and individuals under 18 years (OR 1.45) were consistently associated risk factors. Maxillary anterior teeth accounted for 82.7% of injuries.
conclusionIn conclusion, dental injuries are significantly associated with OCF trauma and hold substantial forensic importance. Routine dental examination should be integrated into trauma assessment and forensic investigations, with future research focusing on standardized classification systems and multicenter prospective studies.
