“…Noise in the dental practice setting causes an unpleasant experience [19]. As shown in the study by Lee et al [20], the highest dental practice noise level at the distance of 100 cm is 77 dB, and 82.5 dB for milling machines. This suggests that the emergence of milling machines may cause a louder noise, which calls for attention.…”

Used in close proximity to dental practitioners, dental tools and devices, such as hand pieces, have been a possible risk factor to hearing loss due to the noises they produce. Recently, additional technologies such as CAD/CAM (Computer Aided Design/Computer Aided Manufacturing) milling machines have been used in the dental environment and have emerged as a new contributing noise source. This has created an issue in fostering a pleasant hospital environment. Currently, because of issues with installing and manufacturing noise-reducing products, the technology is impractical and insufficient relative to its costly nature. In this experiment, in order to create a safe working environment, we hoped to analyze the noise produced and determine a practical method to attenuate the noises coming from CAD/CAM dental milling machines. In this research, the cause for a noise and the noise characteristics were analyzed by observing and measuring the sound from a milling machine and the possibility of reducing noise in an experimental setting was examined using a noise recorded from a real milling machine. Since a milling machine generates noise mainly due to vibration of the dust collector, the possibility of reducing noise was examined by controlling vibration. This study was conducted to understand the cause for noise from the milling machine and verify the possibility of improving noise by a tactile transducer.

“…Lee et al reported that the noise of ultrasonic scalers alone was 58.0±3.36 dB(A), compared to 63.4±1.12 dB(A) when ultrasonic scalers and saliva ejectors were used, and 70.5±0.98 dB(A) when ultrasonic scalers and high-volume aspirators were used. Therefore, there was a significant difference in noise when an ultrasonic scaler was used alone versus coupling the ultrasonic scaler with suction [ 20 ]. Since dental suction cannot be omitted when scaling, these 2 sources of noise generated during scaling should always be considered together.…”

Purpose Dental fear hinders patients from receiving appropriate dental treatment. In particular, the noise generated by high-speed air turbines and ultrasonic scalers can adversely affect patients. Many efforts have been made to reduce the discomfort caused by noise, but no methods are definitively recommended. The purpose of this study was to determine the efficacy of active noise-canceling (ANC) headphones in reducing the pain and discomfort associated with dental scaling. Methods Fifty-five patients requiring scaling and root planing, aged ≥19 years and showing no auditory problems, were included. Scaling was performed for the bilateral maxillary molars and premolars while patients wore headphones, with ANC turned either on or off. The degree of noise and pain reduction in the on and off conditions were surveyed using a visual analog scale (VAS). The Wilcoxon signed-rank test was performed to compare noise- and pain-related discomfort with ANC turned on and off. Results The sample included 28 men and 27 women with a mean age of 45.45±13.12 years. The average noise-related discomfort score was 3.84±2.12 and 2.95±1.99 when noise-canceling was turned off and on, respectively, with a statistically significant difference ( P <0.05). Similarly, the average pain-related discomfort score was 3.78±2.00 and 3.09±1.96 when noise-canceling was turned off and on, respectively, which was a statistically significant difference ( P <0.05). Conclusions The use of ANC headphones seems to reduce the discomfort caused by noise and pain in patients undergoing scaling.

“…Jang [8] reported that 46.5% of respondents complained of coughing due to alginate or stone dust inhalation and 61.1% of experienced respondents complained of coughing. Lee et al [9] reported that noises from ultrasonic scalers, high- and low-speed handpieces, and dental suction affect the hearing of DHs.…”

BackgroundThe aim of this study was to evaluate the awareness of occupational hazards and personal protective equipment use among dental hygienists (DHs).MethodsA total of 271 self-administered questionnaires were obtained from 280 DHs working at dental hospitals or clinics in Daegu and Gyeongsangbuk-do, Korea.ResultsThe occupational hazards included work involving dust (94.1%), volatile substances (86.0%), noise (97.0%), and light-curing units (96.7%). The proportion of dental hygiene tasks that participants perceived as harmful were 42.4%, 51.7%, 9.2%, and 31.4% in the same order as above. The proportion of participants who used dust-proof masks during work involving dust was 1.1%. Those who wore gas-proof masks and gloves for work using volatile substances were 0.7% and 31.2%, respectively. Participants who used goggles for work involving light-curing units were 31.0%. None of the participants used ear plugs for work involving noise. A total of 22.9% of the participants recognized the Material Safety Data Sheet, while 79.7% had never been educated about harmful work environments.ConclusionWhen compared to exposure status and perception of occupational hazards, the level of protective equipment use was very low. Extra measures to increase DHs’ use of personal protective equipment are necessary.
