Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The study is designed as a crossover study so that all enrolled patients will undergo the test intervention prior to crossing over to undergo the control intervention. Prior to receving the test intervention, all participants of the study receive a whole mouth clean for plaque and calculus removal in prior visits of the study. Participants are required to refrain from oral hygiene practices from their six anterior maxillary teeth for at least sixty hours in order to cultivate a biofilm (plaque) on these teeth which were disclosed prior to using the test intervention to remove this disclosed biofilm (plaque). The test intervention is the usage of air polishing devices in conjunction with a novel handpiece (EMS Airflow® MAX handpiece) for dental prophylaxis in healthy patients or for the treatment of gingivitis or peridontitis. This test intervention is a novel handpiece that has been released by the manufacturer of this air polishing device system (EMS) and has been reported by the manufacturer to be more efficient, produce less aerosols and be more comfortable than the conventional handpiece (control intervention) that was previously on the market. The intervention will be delivered in person by a qualified dentist who is undertaking specialty training to become a periodontist at the Sydney Dental Hospital. Only the six front upper teeth will receive the test intervention on the outer (labial) surfaces. The test intervention will be administered on one occasion only and is typically used for minutes at a time. The washout period for the study is four weeks.

Treatment: Devices
Comparator / control treatment
The control treatment is the usage of air polishing devices in conjunction with the conventional handpiece (EMS Airflow® handpiece) for dental prophylaxis in healthy patients or for the treatment of gingivitis or peridontitis. This treatment is administered professionally in the dental chair for the primary purpose of removing stains and biofilm and is typically used for minutes at a time. Prior to receving the control intervention, all participants of the study receive a whole mouth clean for plaque and calculus removal. Additionally there was a four week crossover period between the use of the test intervention and the control intervention. Patients are required to refrain from oral hygiene practices from their six anterior maxillary teeth for atleast sixty hours in order to cultivate a biofilm (plaque) on these teeth which were disclosed prior to use of the control intervention to remove this disclosed biofilm (plaque). The intervention will be delivered in person by a qualified dentist who is undertaking specialty training to become a periodontist at the Sydney Dental Hospital.

Summary
Brief summary
Clinical, microbiological and histological studies have confirmed the safety and efficacy of air polishing devices with the use of glycine and erythritol powder for the removal of biofilm in prophylaxis and in the treatment of periodontitis and peri-implantitis (Petersilka, 2011). There appears to be minimal scientifically validated or published data in the current literature base pertaining to the novel Airflow® MAX handpiece. This study is intended to provide an initial investigation regarding the the efficacy, safety, patient reported outcomes and aerosol generation of an air polishing device used in dentistry in conjunction with a novel EMS Airflow® MAX handpiece as compared to the conventional EMS Airflow® handpiece. The hypothesis is that the EMS Airflow® MAX handpiece is as safe and efficacious as the conventional EMS Airflow® handpiece in professional prophylaxis (biofilm and stain removal).
