Abstract

Background: Aerosols containing disease-causing microorganisms are produced during oral diagnosis and treatment can cause secondary contamination.

Aim: To investigate the use of graphene material for air disinfection in dental clinics by leveraging its adsorption and antibacterial properties.

Methods: Patients who received ultrasonic cleaning at our hospital from April 2023 to April 2024. They were randomly assigned to three groups (n = 20 each): Graphene nanocomposite material suction group (Group A), ordinary filter suction group (Group B), and no air suction device group (Group C). The air quality and air colony count in the clinic rooms were assessed before, during, and after the procedure. Additionally, bacterial colony counts were obtained from the air outlets of the suction devices and the filter screens in Groups A and B.

Results: Before ultrasonic cleaning, no significant differences in air quality PM_2.5 and colony counts were observed among the three groups. However, significant differences in air quality PM_2.5 and colony counts were noted among the three groups during ultrasonic cleaning and after ultrasonic treatment. Additionally, the number of colonies on the exhaust port of the suction device and the surface of the filter were significantly lower in Group A than in Group B (P = 0.000 and P = 0.000, respectively).

Conclusion: Graphene nanocomposites can effectively sterilize the air in dental clinics by exerting their antimicrobial effects and may be used to reduce secondary pollution.

石墨烯纳米复合材料对牙科诊所空气消毒的功效：随机对照研究。

背景：目的：研究利用石墨烯材料的吸附和抗菌特性，将其用于牙科诊所的空气消毒：方法：2023 年 4 月至 2024 年 4 月在我院接受超声波清洗的患者。他们被随机分配到三组（每组 n = 20）：石墨烯纳米复合材料吸入组（A 组）、普通过滤器吸入组（B 组）和无空气吸入装置组（C 组）。分别在手术前、手术中和手术后对诊室的空气质量和空气菌落计数进行评估。此外，还从 A 组和 B 组抽吸装置的出气口和过滤网上采集了细菌菌落计数：结果：超声波清洗前，三组的空气质量 PM2.5 和菌落计数无明显差异。然而，在超声波清洗过程中和超声波处理后，三组之间的空气质量 PM2.5 和菌落数量存在明显差异。此外，A 组抽吸装置排气口和过滤器表面的菌落数明显低于 B 组（P = 0.000 和 P = 0.000）：石墨烯纳米复合材料通过发挥其抗菌作用，可以有效地对牙科诊所的空气进行杀菌，并可用于减少二次污染。

期刊介绍： The World Journal of Clinical Cases (WJCC) is a high-quality, peer reviewed, open-access journal. The primary task of WJCC is to rapidly publish high-quality original articles, reviews, editorials, and case reports in the field of clinical cases. In order to promote productive academic communication, the peer review process for the WJCC is transparent; to this end, all published manuscripts are accompanied by the anonymized reviewers’ comments as well as the authors’ responses. The primary aims of the WJCC are to improve diagnostic, therapeutic and preventive modalities and the skills of clinicians and to guide clinical practice in clinical cases.
