“…All these factors result in higher noise levels which in turn results in higher fear levels. The results were contrary to a study [27], where the number of respondents who feared hearing the sound of a dental drill and feeling a drill were almost equal. The present study demonstrated that female patients encountered significantly higher fear levels on seeing the drill, hearing the drill and on getting their teeth cleaned (p=0.000).This might be because females are more apprehensive as compared to males with regards to various dental procedures as they have a fear that any uneventful thing during the procedure might affect their aesthetics.…”

“…Female patients showed significantly higher annoyance levels when compared to male patients. The results of our study were similar to a study [27], where it was observed that respondents who were not afraid of visiting a dentist were only 11-18%, depicting that most of the respondents had some degree of fear. But the results were contradictory to another [28], where nearly 60% of the adult respondents felt "annoyed" to "extremely annoyed" with the noises in the dental clinic.…”

Background: Noise is a source of pervasive occupational hazard for practicing dentists and the patients. The sources of dental sounds by various dental equipments can pose as a potential hazard to hearing system and add to the annoyance levels of the patients. The aim of the study was to analyze the noise levels from various equipments and evaluate the effect of acoustic noise stimulus on dental fear and annoyance levels among patients attending different dental clinic setups in Jaipur, India.

“…The sound emitted by dental drills can have a powerful influence on the sound environment in a dental clinic. Indeed, a questionnaire that surveyed patients regarding their impression of dental situations found that approximately half of the respondents experienced an unpleasant feeling when they heard drilling sounds related to dental treatment [ 1 ]. The Occupational Safety and Health Administration mandates that employers provide hearing conservation programs for their employees in workplaces where noise levels are equal to or exceed 85 dB for the eight hour equivalent continuous A-weighted sound pressure level in dB, referenced to 20 micropascals ( L Aeq , 8 h ) [ 2 ].…”

“…An assessment of the physical values associated with the subjective impressions of such sounds may enable modification of the sound of dental drills, thus improving the sound environment at dental clinics. In our previous study [ 1 ], those who answered that the sound of a dental drill was unpleasant tended to be more fearful of dental treatment than the other respondents and the fear of the sound of a dental drill had a strong influence on dental anxiety level. In particular, half of those who answered that they were very fearful had the experience of avoiding a dental treatment.…”

The sound produced by a dental air turbine handpiece (dental drill) can markedly influence the sound environment in a dental clinic. Indeed, many patients report that the sound of a dental drill elicits an unpleasant feeling. Although several manufacturers have attempted to reduce the sound pressure levels produced by dental drills during idling based on ISO 14457, the sound emitted by such drills under active drilling conditions may negatively influence the dental clinic sound environment. The physical metrics related to the unpleasant impressions associated with dental drill sounds have not been determined. In the present study, psychological measurements of dental drill sounds were conducted with the aim of facilitating improvement of the sound environment at dental clinics. Specifically, we examined the impressions elicited by the sounds of 12 types of dental drills in idling and drilling conditions using a semantic differential. The analysis revealed that the impressions of dental drill sounds varied considerably between idling and drilling conditions and among the examined drills. This finding suggests that measuring the sound of a dental drill in idling conditions alone may be insufficient for evaluating the effects of the sound. We related the results of the psychological evaluations to those of measurements of the physical metrics of equivalent continuous A-weighted sound pressure levels (LAeq) and sharpness. Factor analysis indicated that impressions of the dental drill sounds consisted of two factors: “metallic and unpleasant” and “powerful”. LAeq had a strong relationship with “powerful impression”, calculated sharpness was positively related to “metallic impression”, and “unpleasant impression” was predicted by the combination of both LAeq and calculated sharpness. The present analyses indicate that, in addition to a reduction in sound pressure level, refining the frequency components of dental drill sounds is important for creating a comfortable sound environment in dental clinics.

“…Yamada, Ebisu and Kuwano [11] conducted a survey on the effect of the sound of dental drills on the feelings of patients in Japanese dental clinics. They found that among the 11 dental anxiety-provoking stimuli examined, three items including hearing the sound of a dental drill had more influence on dental anxiety than the others.…”

This paper reports the results of a four-part questionnaire survey to assess the effects of the sound of dental equipment on people's perceptions and dental anxiety levels. The convenience sample for the survey comprised 230 dental students and 230 gender and age matched non-dental university students. The subjects were requested to complete the questionnaires themselves. The results show that the sound of dental equipment has a great influence on dental anxiety. Dental students, who are more familiar with the operation of this equipment, are less prone to anxiety when they hear its sound than their non-dental counterparts.
