1 · What the graph read from it

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.

2 · The registry

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

objectivesThe Covid-19 pandemic increased stress, which may have led to more bruxism, TMDs, and thus tooth fractures. While previous studies, primarily from specialized clinics, reported an increase in cracked teeth during the pandemic, this retrospective study aimed to assess whether similar trends were observed in a general dental practice in Bavaria, Germany, which remained fully operational throughout the pandemic. MATERIAL AND

methodsPatient records from 2018 to 2023 (n = 4709 patients, 10,018 visits) were analyzed for symptomatic tooth fractures, categorized as wall/cusp fractures, incomplete cracks, or complete fractures.

resultsStatistical analysis using the Mann-Whitney U test revealed no significant differences in fracture incidence between pre-pandemic (2018-2019), pandemic (2020-2021), and post-pandemic (2022-2023) periods. Mandibular molars were the most frequently affected teeth (7.94%-12.43%), and composite restorations were most associated with fractures (51.85%).

conclusionsContrary to previous findings from endodontic practices, this study found no pandemic-related surge in tooth fractures, suggesting that referral bias or patient selection in specialized settings may influence reported trends.
