“…However, from the experiment results and what is claimed on the QuietOn website, speech frequencies with this range were significantly suppressed. Based on this, the authors are in agreement with Kim et al 17 that while QuietOn can reduce some dental surgery background noise it would not meet the requirements of suppressing drill noise while also enabling verbal communication from dentist and dental nurse to the patient.…”

“…The results shown in this study plus four commercially-available ANC devices tested in a recent study by Kim et al, 17 found that the QuietOn device had the better characteristics overall. However, there is still a clear need for a device that is able to target dental handpiece noise and reduce the anxiety-inducing effect of dental drill noise for patients, while maintaining verbal communication.…”

“…This is in agreement with the recent work by Kim et al (2022). 17 According to the QuietOn website, the device claims to focus on suppressing the noise below 1kHz and will just function as a passive insulation for higher frequencies. 30…”

“…Producing anti-noise in the acoustic domain is also technically challenging for frequencies above 1kHz as the “zone of quiet” is inversely proportional to the peak frequency to be reduced. 16 A recent study by Kim et al 17 concluded that QuietOn Dental (QuietOn Ltd., Kempele, Finland) had the best characteristics of the four commercially-available devices tested but was still unsuitable overall and further development was needed.…”

Dental drill noise reduction using a commercially-available earplug device

Aim: The dental handpiece noise in a dental surgery is concerning to both patients and staff as a major cause of dental phobia in patients and potential hearing loss in clinical staff. High-frequency noise generated by dental handpieces is considered to be the worst of the many noises in a dental clinic. Methods to reduce this noise have been proposed and either passive or active noise reduction headphones are often suggested. However, in a dental surgery environment, the need for good verbal communication with the patient needs to be maintained. As a result, this paper aims to evaluate one proprietary anti-noise device considered suitable for this specific purpose. Methods: Lab-based experiments were set up and carried out to evaluate QuietOn, using GRAS 43AG-1 Ear and Cheek Simulator to mimic a section of the human head and ear to represent the acoustic characteristics of an actual ear. Two types of dental drill noise recordings, one for electric motor-driven and another one for air turbine-driven, were played back through high-definition speakers. Sound data captured by the simulator are then visualised and plotted using MATLAB for analysis. Main findings: QuietOn is effective at low frequencies (< 1kHz). However, when dealing with high-frequency noise such as dental handpieces it is ineffective yet subdues verbal communication. Conclusions: Further development of passive or active noise cancellation earplugs is still needed to target dental handpiece noise while maintaining verbal communication.

“…We are looking to perform broader studies in this area of pediatric dentistry, as we can see that it is not only an important part of children's dental treatment but also a great area for the development of the VR industry. We also believe that noise reduction devices and computerized anesthesia instruments could make VR goggles more effective in order to help children undergoing dental procedures [40,41].…”

Effectiveness of Virtual Reality Goggles as Distraction for Children in Dental Care—A Narrative Review

et al. 2023

View full text Add to dashboard Cite

Introduction: One of the main challenges in pediatric dentistry is to provide a favorable experience to the patient, and the success of the treatment depends on this to a large extent. For this reason, multiple methods have arisen, among which are virtual reality glasses, that try to facilitate the management of behavior in the dental office by reducing the dental anxiety of patients. Objectives: The effectiveness of the use of virtual reality glasses as a distraction in pediatric dentistry was studied. In addition, a bibliographic review was performed to determine whether the use of virtual reality reduces anxiety and improves the behavior of children during their dental consultations and dental treatments. Methodology: To obtain the information, we performed a bibliographic review using electronic bibliographic sources from scientific databases, high-impact journals and specialized search engines. Results and Discussion: It is relatively easy to obtain information on the level of dental anxiety of the child patient by means of different scales and the use of a digital pulse oximeter, which helps us to know the effectiveness of the use of virtual reality glasses at the time of the dental procedure. The greatest controversy is found in cases in which it is not possible to adjust them because of the age and size of the child or because of the personal use of glasses. Conclusions: There are multiple studies that confirm the effectiveness of the use of virtual reality glasses as a distraction in pediatric dentistry, and these studies support the effectiveness of virtual reality glasses in reducing dental anxiety and improving the behavior of patients during their consultations and dental treatments.

AimIf surgical guide fabrication is introduced in a dental education program, a digital and conventional workflow can be used. This study evaluated operator preference, perceived difficulty and effectiveness and operating time of both fabrication methods.Materials and MethodsForty participants in a university setting (students, n = 20; dentists, n = 20) with varying levels of dental experience, but no experience in surgical guide fabrication, were randomly assigned to consecutively fabricate surgical guides on a standardized training model, with either the digital or conventional workflow first. The operating time was measured, and operator preference and the perception of difficulty and effectiveness were assessed with a questionnaire. T tests were used for statistical analysis (α = .05).ResultOf the students, 95% preferred the digital workflow and of the dentists 70%. The perceived difficulty of the digital workflow was significantly lower than the conventional workflow in the student group. Both groups perceived the digital workflow to be more effective. The mean operating time (mm:ss) amounted 12:34 ± 2:24 (students) and 18:07 ± 6:03 (dentists) for the digital, and 22:20 ± 3:59 (students) and 20:16 ± 4:03 (dentists) for the conventional workflow.ConclusionBoth students and dentists prefer the digital workflow for surgical guide fabrication. Students perceive the digital workflow as less difficult and more effective than the conventional workflow. The operating time for surgical guide fabrication is shorter with a digital workflow. This study indicates that digital fabrication techniques for surgical guides are preferred to be incorporated into the dental curriculum to teach students about treatment planning in implant dentistry.
