Dental personnel may be at particular risk due to their exposure to high levels of noise from dental equipment. Despite existing regulations and guidelines, there is limited understanding of cumulative noise exposure in dental teaching hospitals, particularly with respect to compliance with occupational standards. The aim of this study is to quantify the levels of noise exposure experienced by dental personnel at a dental teaching hospital.<\/jats:p>\n <\/jats:sec>\n \n Materials & Methods<\/jats:title>\n Data collection involved acoustic evaluations of five commonly used dental equipment and noise measurements in five distinct hospital locations in the Department of Restorative Dentistry. Reverberation time, ambient noise and noise emitted by equipment were assessed using calibrated instruments. Data analysis was carried out, and results were compared with regulatory guidelines.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n Reverberation times ranged from 0.3 to 0.6\u2009s, and ambient noise ranged from 31\u2009dB(A) to 43\u2009dB(A), meeting acoustic design standards. Noise from dental equipment ranged from 53\u2009dB(A) with the ultrasonic scaler to 83\u2009dB(A) with the high\u2010volume suction. Operational room noises ranged from 65\u2009dB(A) in the dental hygiene clinic to 84\u2009dB(A) in the plaster room.<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n The teaching hospital examined is at low risk of excessive noise exposure due to compliance with both Irish and United Kingdom noise regulations. However, noise levels within the plaster laboratory and from the high\u2010volume suction exceeded 80\u2009dB. Dental teaching clinics should take measures to reduce noise levels in areas and with equipment where noise levels exceed recommended limits. Regular monitoring of noise exposure in such facilities is recommended.<\/jats:p>\n <\/jats:sec>","DOI":"10.1111\/eje.70058","type":"journal-article","created":{"date-parts":[[2025,10,30]],"date-time":"2025-10-30T09:17:02Z","timestamp":1761815822000},"page":"1046-1051","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Noise Exposure in a Dental Teaching Hospital: Investigations and Recommendations for Dental Personnel"],"prefix":"10.1111","volume":"30","author":[{"given":"Liath O'","family":"Shea","sequence":"first","affiliation":[{"name":"School of Clinical Therapies University College Cork Cork Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amr","family":"El Refaie","sequence":"additional","affiliation":[{"name":"School of Clinical Therapies University College Cork Cork Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ciara","family":"Moloney","sequence":"additional","affiliation":[{"name":"School of Clinical Therapies University College Cork Cork Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9421-5392","authenticated-orcid":false,"given":"Niamh","family":"Coffey","sequence":"additional","affiliation":[{"name":"Cork University Dental School and Hospital University College Cork Cork Ireland"},{"name":"School of Dentistry RCSI University of Medical and Health Sciences Dublin Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,10,30]]},"reference":[{"issue":"2","key":"e_1_2_9_2_1","first-page":"208","article-title":"Noise\u2010Induced Hearing Loss (NIHL): Literature Review With a Focus on Occupational Medicine","volume":"17","author":"Metidieri M.
