“…The high-speed air dental drill (driven by an air turbine) was first designed in the late 1940s by New Zealand's Sir John Walsh. Since then, handpieces have been evolved to typically operate in the range of 180,000 to 330,000rpm, with some running at up to 400,000rpm [6].…”

Aim: A pilot study was conducted with the aim of developing a system to protect the eyes, nose, and mouth from the aerosol generated from a high-speed dental handpiece during the COVID-19 pandemic. Background: The SARS-CoV-2 virus is known to be present in the saliva of an infected individual during the contagious viral shedding phase of the disease. The use of rotary dental instruments places oral health practitioners at risk of contracting COVID-19 from infected individuals. In particular, it is very difficult to protect the mucous membranes of the face against the extremely fine aerosol produced from a high-speed dental handpiece. Objectives: This study aimed to develop and test a novel PPE system for use during the COVID-19 pandemic. An air-fed spray-painting mask was used under a plastic hood to protect against the aerosol from a high-speed dental handpiece. This was found to be superior compared to hospital-issued N-95 masks and eye protection in our test model. Methods: Subjects donned various forms of PPE whilst using a high-speed dental handpiece in a confined cubicle. The efficacy of each form of PPE was evaluated by adding fluorescein to the water coolant supply line of a high-speed dental handpiece before checking for facial contamination with an ophthalmology slit lamp. Results: Under our test conditions, the N-95 mask did not prevent nasal and mouth contaminations, but the combination of an air-fed mask with a sealed hood prevented these contaminations. Although goggles worn tightly did prevent contamination, the air-fed mask system was far more comfortable and did not fog up. Discussion: Under the rigorous test conditions of our model, we found hospital-issued PPE ineffective. We also found the single strategy of using positive airflow into a face mask ineffective, even with extremely high levels of airflow. Complete protection was only achieved reliably by the combination of physically sealing off the face from the surrounding airspace and using the air-fed system to provide an external source of air to breathe. We effectively made the clinical equivalent of a dive bell helmet. The air-fed mask is supplied by a standard dental air compressor and is simple to install for someone familiar with the technical aspects of compressors. The compressor does not rely on a filter and proves effective with cheap and easily accessible disposable items. Conclusion: Under rigorous testing conditions, the developed air-fed mask system with a sealed hood on low flow performed better than hospital-issued PPE against high-speed dental aerosol protection. The developed system protects the operators from the air of the room contaminated with aerosol and brings in safe air from the outside for them to breathe.

“…), created a work group and developed an SDDxT—the Dental Diagnostic System (DDS). 26-28 We designed DDS as an interface terminology. This means that it was meant to be sufficiently concise to be navigable within the electronic health record (EHR) while still being rich enough to capture diagnoses seen in the dental clinic.…”

Background Standardized dental diagnostic terminologies (SDDxTs) were introduced decades ago. Their use has been on the rise, accompanying the adoption of electronic health records (EHRs). One of the most broadly used terminologies is the Dental Diagnostic System (DDS). Our aim was to assess the adoption of SDDxTs by US dental schools by using the Rogers diffusion of innovations framework, focusing on the DDS. Methods The authors electronically surveyed clinic deans in all US dental schools (n = 61) to determine use of an EHR and SDDxT, perceived barriers to adoption of an SDDxT, and the effect of implementing an SDDxT on clinical productivity. Results The response rate was 57%. Of the 35 responses, 91% reported using an EHR to document patient care, with 84% using axiUm, and 69% reported using an SDDxT to document patient diagnoses; 41% used the DDS. Fifty-four percent of those who did not use an SDDxT had considered adopting the DDS, but 39% had not, citing barriers such as complexity and compatibility. Conclusions Adoption of an SDDxT, particularly the DDS, is on the rise. Nevertheless, a large number of institutions are in the Rogers late majority and laggards categories with respect to adoption. Several factors may discourage adoption, including the inability to try out the terminology on a small scale, poor usability within the EHR, the fact that it would be a cultural shift in practice, and a perception of unclear benefits. However, the consolidation of the DDS and American Dental Association terminology efforts stands to encourage adoption.

“…Highspeed dental air turbine handpieces fomented a revolution and significantly altered dental practice. 8 Air turbine handpieces attained popularity and are actively used in clinical dentistry. In North America, high-speed handpieces are used for the majority of clinical procedures involving fixed prosthodontics in pre-doctoral programs.…”

Objective: Low-speed high-torque handpieces are popular for the pre-clinical training of dental students. However, in clinical practice, high-speed air turbine handpieces are commonly used. This dissimilarity creates a gap between pre-clinical and clinical training skills. The current study sought to evaluate the effects of the use of high-speed and low-speed handpieces by dental students during their pre-clinical training.Methods: Twenty-one undergraduate dental students at the College of Dentistry of Taibah University participated in this study. Each student was asked to prepare class I cavities using high-speed air turbine and lowspeed/high-torque handpieces. The time required for cavity preparation was recorded by the authors. The prepared cavities were evaluated for quality and skill using a six-point scale. The data were statistically analysed with paired t and ManneWhitney tests.Results: There was no significant difference in cavity preparation time between the low-speed and high-speed handpieces (538.29 and 483.76 s, respectively). The evaluations of the cavities revealed no difference in the quality of preparations between the low-and high-speed handpieces. Additionally, no significant difference in the surface roughness of the preparations was observed.Conclusions: The type of handpiece did not influence the learning capabilities of the undergraduate dental students in the preparation of preparing class I cavities. This study did not observe any significant differences between the cavities that were prepared by our students using either high-speed or low-speed handpieces.
