Abstract

Background: Maintaining biosafety in dental practice involves the effective elimination of aerosols produced during dental treatment.

Objectives: To assess the quantity of aerosols and aerobic bacteria in the air during the treatment of caries.

Material and methods: The study involved 60 patients with a total of 60 molar teeth (n = 60) in the mandible who were divided into 2 groups based on caries treatment method. Group 1 (G1, n = 30) received treatment with a conventional dental turbine (W&H Synea TA-98LC; W&H, Burmoos, Austria), while group 2 (G2, n = 30) underwent treatment with an Er:YAG (erbium-doped yttrium aluminium garnet) laser (LightWalker, Fotona, Slovenia). Measurements of aerosol particles between 0.3 Ęm and 10.0 Ęm near the operatorfs mouth were taken using the PC200 laser particle counter (Trotec GmbH, Schwerin, Germany). The number of aerobic bacteria in the air was determined using 60 Petri plates with a microbiological medium (Columbia agar with 5% sheep blood) and the sedimentation method. A control group (G3) was established to measure initial aerosol levels and initial total number of bacteria colony-forming units (CFUs) before each treatment.

Results: In G1 (dental turbine), the median value of aerosol particles was 57,021 (42,564.67,568), while in G2 (Er:YAG laser), it was significantly lower at 33,318 (28,463.35,484) (p < 0.001). The median total bacteria count per cubic meter of air in G1 (conventional dental turbine + high volume evacuator (HVE)), G2 (Er:YAG laser + HVE) and G3 (control group before caries treatment) were 734 (420.988), 158 (96.288) and 48 (32.74), respectively, with a statistically significant difference between the groups (p < 0.001).

Conclusions: The use of Er:YAG laser during caries treatment resulted in a 41.6% reduction in aerosol amounts and a 78.5% decrease in the total bacterial count (TBC) compared to treatment with a dental turbine.

分析 Er:YAG 激光辅助龋齿治疗过程中产生的气溶胶：随机临床试验

背景：要在牙科实践中保持生物安全，就必须有效消除牙科治疗过程中产生的气溶胶：评估龋齿治疗过程中空气中气溶胶和需氧细菌的数量：根据龋齿治疗方法将 60 名下颌磨牙患者（n = 60）分为两组。第一组（G1，n = 30）使用传统牙科涡轮机（W&H Synea TA-98LC；W&H，Burmoos，奥地利）进行治疗，第二组（G2，n = 30）使用 Er:YAG（掺铒钇铝石榴石）激光器（LightWalker，Fotona，斯洛文尼亚）进行治疗。使用 PC200 激光粒子计数器（Trotec GmbH，德国施维林）测量操作者口腔附近 0.3 Ęm 至 10.0 Ęm 的气溶胶粒子。使用装有微生物培养基（含 5%绵羊血的哥伦比亚琼脂）的 60 个培养皿和沉降法测定空气中好氧细菌的数量。设立了一个对照组（G3），用于测量每次处理前的初始气溶胶水平和初始菌落形成单位（CFU）总数：在 G1 组（牙科涡轮机）中，气溶胶颗粒的中值为 57,021 (42,564.67,568) 个，而在 G2 组（Er:YAG 激光）中，气溶胶颗粒的中值明显较低，为 33,318 (28,463.35,484) 个（p < 0.001）。G1（传统牙科涡轮机 + 高容量排空器 (HVE)）、G2（Er:YAG 激光器 + HVE）和 G3（龋齿治疗前对照组）每立方米空气细菌总数的中位数分别为 734 (420.988)、158 (96.288) 和 48 (32.74)，组间差异有统计学意义（P < 0.001）：结论：与使用牙科涡轮机治疗相比，在龋齿治疗过程中使用 Er:YAG 激光可使气溶胶量减少 41.6%，细菌总数减少 78.5%。

期刊介绍： Advances in Clinical and Experimental Medicine has been published by the Wroclaw Medical University since 1992. Establishing the medical journal was the idea of Prof. Bogumił Halawa, Chair of the Department of Cardiology, and was fully supported by the Rector of Wroclaw Medical University, Prof. Zbigniew Knapik. Prof. Halawa was also the first editor-in-chief, between 1992-1997. The journal, then entitled "Postępy Medycyny Klinicznej i Doświadczalnej", appeared quarterly. Prof. Leszek Paradowski was editor-in-chief from 1997-1999. In 1998 he initiated alterations in the profile and cover design of the journal which were accepted by the Editorial Board. The title was changed to Advances in Clinical and Experimental Medicine. Articles in English were welcomed. A number of outstanding representatives of medical science from Poland and abroad were invited to participate in the newly established International Editorial Staff. Prof. Antonina Harłozińska-Szmyrka was editor-in-chief in years 2000-2005, in years 2006-2007 once again prof. Leszek Paradowski and prof. Maria Podolak-Dawidziak was editor-in-chief in years 2008-2016. Since 2017 the editor-in chief is prof. Maciej Bagłaj. Since July 2005, original papers have been published only in English. Case reports are no longer accepted. The manuscripts are reviewed by two independent reviewers and a statistical reviewer, and English texts are proofread by a native speaker. The journal has been indexed in several databases: Scopus, Ulrich’sTM International Periodicals Directory, Index Copernicus and since 2007 in Thomson Reuters databases: Science Citation Index Expanded i Journal Citation Reports/Science Edition. In 2010 the journal obtained Impact Factor which is now 1.179 pts. Articles published in the journal are worth 15 points among Polish journals according to the Polish Committee for Scientific Research and 169.43 points according to the Index Copernicus. Since November 7, 2012, Advances in Clinical and Experimental Medicine has been indexed and included in National Library of Medicine’s MEDLINE database. English abstracts printed in the journal are included and searchable using PubMed http://www.ncbi.nlm.nih.gov/pubmed.
