Chairside prosthesis adjustment procedures generate contaminated acrylic particle debris that include visible splatter (particles >50 μm) as well as invisible aerosols (<50 µm). The purpose of this study was to evaluate the effectiveness of a chairside acrylic adjustment cabinet (CAAC) in reducing airborne aerosol particles (<10 µm) and visible acrylic debris, time required for airborne aerosols to return to baseline levels after an acrylic adjustment procedure, and the effect on operatory turnover time.
Materials and methods
A total of 40 acrylic adjustment procedures were carried out in a simulated setting with (experiment) and without (control) a CAAC. Standardized acrylic samples of self‐polymerized, and heat polymerized polymethylmethacrylate resins, Triad™ and Fastray™ custom tray materials were evaluated. Airborne aerosol measurements were done using a handheld Lase.r Particle Counter for absolute particle counts of sizes 0.3, 0.5, 1.0, 2.5, 5.0, and 10.0 μm before, during, and immediately after adjustment and 10 minutes postadjustment. Spread of aerosols was assessed at three distinct locations within the dental operatory specific to the provider, the patient, and the caregiver/guest. Visible acrylic debris and operatory turnover time were evaluated immediately postadjustments by a blinded investigator. Repeated measures ANOVA was used to estimate group effect, time effect and interaction between group and time for air particle analysis. Independent samples T‐tests were used for group differences between operatory turnover time, and time for aerosols to return to baseline. Chi‐square test was used for visible surface analysis.
Results
In the control group, total aerosol particle counts increased from 6542.7 ± 162.6 particles at baseline to 598378.7 ± 586363.2 and 367569.9 ± 432220.8 particles during and immediately postadjustment, respectively. Adjustments made in the experiment group led to significantly reduced aerosol counts during (97738.9 ± 97866.5) and immediately postadjustment (19786.5 ± 14004.9; F = 17.8, p = 0.006). Similar trends were noted for the patient and guest positions. Time for aerosol particles to return to baseline was significantly lower in the experiment group (20.56 ± 14.5 minutes) compared to the control group (37.9 ± 31.96 minutes; p = 0.03). Visible acrylic debris analysis showed a significant decrease of 78% in the experiment group (p < 0.001). No significant differences were noted in operatory turnover time between the two groups (p = 0.61).
Conclusions
Acrylic adjustment procedures generated aerosols of particle sizes less than 10 µm and were measured in significant quantities throughout the dental operatory for up to 115 minutes. Chairside acrylic adjustment cabinets significantly decreased airborne aerosols, visible acrylic particle debris, and reduced the time for airborne aerosols to return to baseline levels.</description><identifier>ISSN: 1059-941X</identifier><identifier>EISSN: 1532-849X</identifier><identifier>DOI: 10.1111/jopr.13463</identifier><identifier>PMID: 34855263</identifier><language>eng</language><publisher>United States: Wiley Subscription Services, Inc</publisher><subject>acrylic dust ; Aerosols ; Chairside prosthesis adjustment ; contamination ; dental grinding box ; Dental restorative materials ; Experiments ; patient safety ; Polymethylmethacrylate ; provider safety ; Resins ; ventilation</subject><ispartof>Journal of prosthodontics, 2022-07, Vol.31 (6), p.488-495</ispartof><rights>2021 by the American College of Prosthodontists.</rights><rights>2022 American College of Prosthodontists.</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c3573-de87a2c69ab86aae066cd702b41b99703b43cb0cff84e0f78de70115ed1f7ae23</citedby><cites>FETCH-LOGICAL-c3573-de87a2c69ab86aae066cd702b41b99703b43cb0cff84e0f78de70115ed1f7ae23</cites><orcidid>0000-0002-6755-6535</orcidid></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://onlinelibrary.wiley.com/doi/pdf/10.1111%2Fjopr.13463$$EPDF$$P50$$Gwiley$$H</linktopdf><linktohtml>$$Uhttps://onlinelibrary.wiley.com/doi/full/10.1111%2Fjopr.13463$$EHTML$$P50$$Gwiley$$H</linktohtml><link.rule.ids>314,780,784,1416,27915,27916,45565,45566</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/34855263$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Srivastava, Akanksha</creatorcontrib><creatorcontrib>Andersen, Michael R.</creatorcontrib><creatorcontrib>Alshehri, Abdulkareem M.</creatorcontrib><creatorcontrib>Lara, Bryan</creatorcontrib><creatorcontrib>Bashiri, Rafiullah</creatorcontrib><creatorcontrib>Li, Guojun</creatorcontrib><creatorcontrib>Chambers, Mark S.</creatorcontrib><title>Effectiveness of a Chairside Acrylic Adjustment Cabinet in Reducing Dental Acrylic Debris and Aerosols</title><title>Journal of prosthodontics</title><addtitle>J Prosthodont</addtitle><description>Purpose
