Background: Noise levels encountered during the dental treatments in different departments have deleterious effects on the ears of dental healthcare providers and there is scarcity of data in the literature in Saudi Arabia. Hence, the aim of the study was to determine the noise levels resulting from the usage of different specialty instruments and equipment. Material and Methods: A cross-sectional study was conducted to measure the level of noise produced by different specialty instruments and equipment within the dental clinics of the College of Dentistry, Riyadh Elm University (REU), Riyadh. The noise produced during the restorative treatments, endodontics and prosthodontics was recorded objectively using a decibel (dB) meter placed at a distance of 30 cm from the operator's ear. Mean noise levels were calculated and compared among the various specialty treatments using Analysis of Variance (ANOVA). Furthermore, Tukey's test was applied to perform a pairwise comparison between the groups. Results: An overall noise of 73.83 ± 4.39 dB was found to be generated within the dental clinical setting. A highest sound level of 79.44 ± 2.10 dB was observed during restorative treatment followed by 74.14 ± 3.08, 73.22 ± 1.93, 71.39 ± 3.37 and 70.97 ± 4.70 dB for endodontic, periodontal, and prosthodontic treatments, respectively. A statistically significant difference was observed in the noise levels produced from the different specialty treatments (P = 0.000). Conclusion: The greatest noise level was recorded with the use of the amalgamator in restorative dental treatment. It was inferred that the noise emanating from all the specialty dental treatments was below the hazardous levels. Long-term exposure may, however, have adverse effects on auditory as well as general health.
