Involving supernumerary teeth in "qpdb" teeth numbering system.
Article in Scientific reports, 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
Supernumerary teeth are extra-dentation or tooth-like structure that may be present anywhere in the oral cavity. Currently used numbering systems lack a standardized method for identifying supernumerary teeth which might result in misinterpretation and hinder effective collaboration among dental practitioners. A pre-study questionnaire was conducted on 235 dental practitioners, including dentists, interns and clinical dental students to evaluate their previous experience with supernumerary teeth and the numbering systems used to identify them. Of the respondents, only 32% reported using systems to identify supernumeraries while 68% had no experience with any of systems confirming a significant gap in standardized practice highlighting the need for development of a new numbering system. This manuscript presents a novel addition to the existing "qpdb" tooth numbering system for identification of supernumerary teeth, addressing the limitations of existing methods that fail to provide a standardized approach for identifying these extra teeth. The modification introduces the digit zero (0) placed in combination with the tooth number mesially adjacent to the supernumerary (the identifier tooth) as a designation. This approach enables more precise, consistent and communicable identification of supernumerary teeth addressing the limitations of currently available numbering systems.
