Local Delivery of Genistein in Peri-Implant Defects Enhances Osseointegration in Ovariectomized Rats.
Article in Calcified tissue international, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundEstrogen deficiency, a key factor in osteoporosis, may influence peri-implant healing, which requires cautious and individualized planning for dental implant placement. Functionalizing biomaterials with bioactive molecules, such as soy-derived isoflavone, could enhance their osteoconductive potential.
objectiveInvestigate the performance of genistein in the functionalization of bioactive glass and deproteinized bovine bone by sonochemistry on peri-implant bone repair in ovariectomized rats.
methodsIn total, 50 female rats were divided into five groups (n = 10): blood clot (CLOT); bioactive glass (BG); bioactive glass functionalized with genistein (BG + GEN); deproteinized bovine bone (BO); and deproteinized bovine bone functionalized with genistein (BO + GEN). Thirty days after ovariectomy, implants were placed in the tibia of the rats. Calcein and alizarin were administered at 14 and 24 days post-surgery, respectively. The rats were euthanized 28 days after implant placement for analysis.
resultsBO + GEN showed the highest removal torque (5.4 Ncm), significantly higher than BO (2.3 Ncm; p < 0.05), followed by BG + GEN (4.2 Ncm), BG (3.3 Ncm), and CLOT (2.1 Ncm). BG + GEN and BO + GEN upregulated the bone markers (RANKL, OPG, OCN, IBSP) (p < 0.05). Micro-CT revealed higher bone volume percentage (BV/TV) in BO + GEN (11.67%) and BG + GEN (10.51%) versus their controls (p < 0.05). Trabecular separation (Tb.Sp) was significantly reduced in BO + GEN compared to BG (p < 0.05).
conclusionThese findings suggest that genistein can potentiate the osteoconductive properties of clinically used biomaterials, enhancing peri-implant bone repair in ovariectomized rats.
