Foreign Bodies of Dental Iatrogenic Origin Displaced in the Maxillary Sinus - A Safety and Efficacy Analysis of a Retrospective Study.
Article in Annals of maxillofacial surgery. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Introduction: Foreign bodies (FB) of the paranasal sinuses are an uncommon clinical entities with the maxillary sinuses being those most frequently affected. According to the literature, 60% of paranasal sinus FB are of iatrogenic origin, while 25% are of traumatic origin. This article aims to present an iatrogenic origin series of cases of FB displaced or projecting into the maxillary sinus. Materials and Methods: In this retrospective study, the presence of the foreign body was revealed with radiologic methods and confirmed during the operation with macroscopic or later with histopathologic examination. All cases were treated with osteoplasty with vascularised pedicled bone flap or through minimally invasive intraoral procedure. Results: A total of 27 patients were included in our study, 14 men and 13 women. The age range was 18-65 years with mean age of 46.14 (standard deviation = 10.35) years. Foreign body was displaced fragments of teeth in 11 patients (40.27%), complete teeth in four patients (14.81%), dental implants in five patients (18.51%), dental impression material in 2 cases (7,40%), gutta percha cone in two patients (7.40%), endodontic sealer associated with aspergillosis in two patients (7.40%), and dental burr in one patient (3.7%). The time between dental foreign body displacement and the surgical intervention for its removal was critical for the occurrence of sinusitis. All operated patients remained asymptomatic during a follow-up of at least 1 year. Discussion: Prompt intervention for removal of FB eliminates the risk for chronic inflammation of the affected maxillary sinus and reduces the odds for sequelae.
