Using panoramic radiographs to assess the probability of causing oroantral communication following tooth removal. A retrospective cross-sectional study.
Article in Clinical oral investigations, 2025. 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
objectivesTo preoperatively assess the probability of oroantral communication (OAC) following the removal of maxillary (pre)molars using panoramic radiographs (PAN) and to assess the OAC-rate. MATERIALS AND
methodsDuring a 4,5-year period, patient characteristics of removals of maxillary (pre-)molars were recorded: 'sex', age, 'sidedness', 'type of tooth', 'reason for removal'' and 'occurrence of OAC'. On the PAN of OAC-cases and of 100 control cases, the 'Fraction of the Root Overlapping the Maxillary Sinus' (FROMS) was calculated. The OAC-rate was reported overall, per tooth type and for four diagnostic classes: A: no overlap, B: 0.1-25%, C: 25.1-50% and D > 50% overlap. Univariate tests and regression analysis were performed to test the association between OAC-rate and 'FROMS', 'sex', age, 'sidedness', 'type of tooth', 'reason for removal'.
resultsOf 2340 maxillary (pre-)molars removed, 112 resulted in OAC (OAC-rate of 4.8% (95%CI 3.9%-5.7%)) The FROMS diagnostic class was significantly associated with the OAC-rate (χ2 = 42.90 df3, p < 0.0001). For the four diagnostic classes the risk of OAC was (A) 1.0%, (B) 3.3%. (C) 10.1% and (D) 17.7%. The first molar showed highest OAC-rate with 7.0%. No association between OAC-rate and 'sex', age, 'sidedness', 'type of tooth', 'reason for removal' was found.
conclusionsFROMS is a valid indicator of OAC probability. The overall OAC-rate was 4.8% and was highest in first molar removal. CLINICAL RELEVANCE: Dentists and oral surgeons using PAN to assess OAC probability, can anticipate possible OAC and counsel patients.
