Woodpecker High-Pressure Plasma Air Purifier Q3

The large volume of biological aerosol produced by dental procedures is of great concern to practicing dentists. Introducing new technology from Silicon Valley.  A recent study “Aerodynamic Characteristics and RNA Concentration of SARS-CoV-2 Aerosol in Wuhan Hospitals during COVID-19 Outbreak”,  Yuan Liu, Ph.D et al. used gelatin filters to capture aerosol samples in the patient areas, […]

Flight Defender Aerosol Evacuator

The regulatory decisions made in the next few months will determine our dental careers. This email series is a review of the available evidence for aerosol transmission of SARS-CoV-2 including links to open access journal articles. Bassel Gebrael DDS, Dip. Perio, FRCD(C) Part 1: Understanding mulitphase turbulent gas clouds The main method of transmission of […]

Air exchanges per hour in an operatory with an in-operatory air cleaner. Wuhan hospital study.

How to calculate air exchanges per hour (ACH) in an operatory with an in-operatory air cleaner (HEPA filter unit): The typical dental operatory has an area 100 square feet with an 8 foot ceiling, which gives a volume of 800 cubic feet. Following an aerosol generating procedure, the operatory must be left empty to permit […]

Is Coronavirus viable in aerosol?

According to a recent report by Neeltje van Doremalen, Ph.D. published in the New England Journal of Medicine, 2019-CoV-2 can remain viable and infectious in aerosol for hours and on surfaces for up to 72 hours. “Our results indicate that aerosol and fomite transmission of SARS-CoV-2 is plausible, since the virus can remain viable and […]

Clarithromycin Beneficial with Full Mouth Debridement in Generalized Aggressive Periodontitis?

Methods: Forty patients were randomly assigned to one of two groups: 1) Full Mouth Debridement with Clarithromycin 500mg every 12 hours for 3 days. 2) Full Mouth Debridement with placebo pills. Results: Both groups were effective for clinical and microbiological parameters. The Clarithromycin group presented with lower mean probing depths for pockets ≥ 7mm at […]

Emdogain plus Calcium Phosphate for Two-Wall Defects?

Methods: 52 patients with at least one non-contained infrabony defect ≥ 3 mm and probing ≥ 3 mm were randomly treated with either Emdogain plus biphasic calcium phosphate or Emdogain alone. The primary outcome was a change in clinical attachment up to 12 months. Results: Mean clinical attachment gain of 2.38 mm ± 2.17 mm was […]

Good long term results for tissue grafts?

  Methods: Forty-seven patients with 64 sites with lack of attached gingiva were treated with free gingival grafts and 64 control sites were left untreated.  Patients were recalled every 4 to 6 months.  Gingival recession depth, keratinized tissue width, and probing depth were measured at baseline and extending to the follow up period (18 to […]

Platelet-rich fibrin (PRF) to treat periodontal intrabony defects?

Methods: 36 intrabony defects in 36 individual patients were treated with either demineralized freeze-dried bone allograft (DFDBA) or platelet-rich fibrin (PRF).  Data was collected at baseline and at 6 month follow up and included radiographic bone fill and changes in clinical attachment levels (CAL). Results: Both treatment groups had significant gain in clinical attachment levels […]
