Do ultrasonic instrumentation and air polishing procedures adversely affect dental restorations?
Article in Evidence-based dentistry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
a commentary onEsati J, Amran T, Weiger R, Alsulaimani L, Blatz M B, Eggmann F. Adverse effects of ultrasonic instrumentation and air polishing on dental restorations: a systematic review of laboratory studies. J Esthet Restor Dent 2025; https://doi.org/10.1111/jerd.13428 .
objectiveA systematic review of the literature was conducted, assessing the potential for adverse effects on surface roughness and marginal integrity with use of ultrasonic instrumentation and air polishing on variety of dental restorations. With the aim to guide clinical practice to aid mitigation of adverse effects. DATA SOURCES: Five databases: Cochrane Library, OpenGrey through DANS, PubMed, Scopus, and Web of Science, and supplemental manual searches were used to identify relevant literature. The review adhered to the PRISMA guidelines. STUDY SELECTION: Publications were included between 1978 and 2022. POPULATION: dental restorations or restorative biomaterials in vitro.
interventionultrasonic instrumentation and/or air polishing. Comparison: no debridement procedure or paste polishing. OUTCOME: surface roughness and/or marginal quality. Forty-two laboratory studies were included in the final analysis. The studies evaluated data to answer the following research question: In specimens made of or featuring dental restorations or restorative biomaterials, how does the use of ultrasonic instrumentation and/or air polishing, compared with no debridement procedure or paste polishing, affect the surface roughness and/or marginal quality? DATA EXTRACTION AND SYNTHESIS: Data extracted included: author(s) and year, laboratory studies, biomaterials evaluated, specimen quantity, specimen geometry, grouping methodology, types of ultrasonic and/or air polishing devices used, air polishing powders, device operational settings, application type and duration of ultrasonic and/or air polishing, assessments of surface roughness and marginal quality, and the observed effects on both surface roughness and marginal quality. Biomaterial assessed included: porcelain fused to metal (PFM), zirconia (ZrO
resultsUltrasonic instrumentation and air polishing both negatively impacted surface roughness. Air polishing with sodium bicarbonate and calcium carbonate powders had a significantly greater effect on surface roughness, compared with erythritol and glycine powders. The surface roughness for RBCs and RMGICs were the most affected by ultrasonic instrumentation. In comparison, ZrO
conclusionsIt is advised to use air polishing with less abrasive powders, including erythritol and glycine, to mitigate surface damage and changes at the marginal interface. Another important clinical consideration is the type of restorative material. High strength ceramic restorations, such as LDS and ZrO
