Dental laser training and education in postgraduate periodontics programs in North America

The application of various lasers to treat periodontal and peri-implant diseases is gaining momentum. While laser-related dental research is ongoing, it is important to determine if current periodontal training programs are keeping pace with these new treatment modalities and actively incorporating them into their training.

An electronic survey was created to evaluate the extent to which lasers are currently being used in North American periodontal programs. A brief explanation of the study and a link to the 15-question survey was emailed to 61 periodontal program directors requesting participation in the survey. The data regarding the prevalence of laser training in all the programs, which types of laser devices are used, and which surgical procedures are performed were collected and analyzed.

The response rate was 49.1% (n = 30). Among those responding to the survey, 76.7% (n = 23) of these programs reported providing clinical training in lasers, with the diode laser being the most frequently used (65.2%), followed by carbon dioxide (39.1%), neodymium-doped yttrium aluminum garnet (26.1%), and erbium:yttrium aluminum garnet lasers (26.1%). Two major reasons for not utilizing lasers as part of regular patient care were cost and lack of evidence to support laser efficacy. Three out of seven programs that do not currently use lasers plan to provide laser training in the future. Over half (56.7%) of program directors did not think that lasers would become the standard of periodontal/implant care within the next 10 years, while 20% of them believed that they would.

Laser training and education in postgraduate periodontal programs is still limited, and the majority of periodontal residents are not exposed to many types of laser devices.
