Effect of crown-root ratio in endo-perio treated teeth restored with prosthodontic crowns.
Article in Bioinformation, 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
The crown-root ratio (CRR) plays a crucial role in determining the biomechanical stability and long-term prognosis of endo-perio treated teeth restored with prosthodontic crowns. Therefore, it is of interest to assess the influence of CRR on the clinical performance and survival of such teeth in a sample of 60 patients aged 25-65 years. Based on radiographic CRR, teeth were categorized into three groups: favourable (≤1:1), moderate (1:1-1.5:1) and unfavourable (>1.5:1). All patients received standardized endodontic, periodontal and prosthodontic treatment and were evaluated over a 12-month period for probing depth, attachment level, marginal bone changes and crown survival. Teeth with favourable CRR showed minimal bone loss (0.2 mm) and a 100% survival rate, whereas those with unfavourable ratios demonstrated increased bone loss (0.9 mm) and reduced survival (75%) (p < 0.05). Thus, we show that prognosis declines progressively as CRR becomes less favourable, highlighting the importance of radiographic CRR assessment in treatment planning for enhancing the long-term success of prosthodontically restored endo-perio treated teeth.
