Often the treatment includes distalisaton of the mandible to restore the dentition in centric relation.

The authors have a concern that there could be a group of patients with both conditions where distalisation for their tooth wear management would be contrary to their OSA treatment. This paper aims to look at this potential risk.Methods: A literature search was carried out using the following keywords (OSA or sleep apnoea or apnea or snoring or AHI or Epworth score) and for tooth surface loss (TSL or distalisation or centric relation or tooth wear or full mouth rehabilitation).Results: No studies were identified which considered the effect of mandibular distalisation on OSA.Conclusion: There is a theoretical risk that dental treatment involving distalisation may adversely affect patients at risk of OSA or worsening their condition due to the modification of airway patency.

PA+E group presented highest microleakage mean values after thermocycling. Spearman's correlation showed a strong correlation between microleakage and μTBS. The PA+E group improved immediate adhesion and E group promoted a more stable μTBS in the long-term adhesion of universal adhesive.

Meanwhile, verbal communication between the dentist and patient is essential. Conventional active noise-cancelling headphones are ineffective for dental drill noise and simply suppress all sound and hinder communication.Method: A compact passive earplug device was designed specifically to attenuate broadband high-frequency noise ranges from 5 to 8 kHz employing an array of quarter wavelength (QW) resonators. This device was 3D printed and tested against white noise to enhance the objectivity of analysis, using a calibrated ear and cheek simulator to effectively measure its performance.Results: The results showed that the resonators produced an average reduction of 27 dB across the targeted frequency range. When compared with two proprietary passive earplugs, this developed passive device prototype was able to attenuate an average of 9 dB more across the target frequency range whilst delivering louder speech signals of 14 dB more. The results also show that using an array of resonators exhibits an accumulated effect of individual resonator performance.Conclusions: This low-cost passive device could have a place in the dental clinic to reduce unwanted drill noise equivalent to the white noise high frequency spectra tested.","PeriodicalId":45686,"journal":{"name":"European Journal of Prosthodontics and Restorative Dentistry","volume":"31 3","pages":"262-277"},"PeriodicalIF":1.3,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10127190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
