Delayed Foreign Body Granuloma Following Sinus Augmentation With Deproteinized Bovine Bone: A Case Report.
Article in Case reports in dentistry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
This report describes an uncommon granulomatous foreign body reaction that developed after lateral sinus augmentation with deproteinized bovine bone mineral (DBBM). The patient presented 5 months postoperatively with an extraoral draining fistula and intraoral swelling that failed to resolve with multiple courses of antibiotics and was initially misdiagnosed as a chronic infection. Early surgical exploration with subsequent histopathological analysis identified multinucleated giant cells enclosing residual graft particles, establishing a diagnosis of a noninfectious foreign body granuloma. Following thorough debridement and a 12-month recovery period, implant placement was carried out successfully, with clinically stable results maintained at 30 months of follow-up. This case illustrates the importance of considering foreign body reactions when evaluating persistent postoperative complications after sinus augmentation and emphasizes the essential role of tissue biopsy in reaching an accurate diagnosis.
