Training and Use of Lasers in Postgraduate Orthodontic Programs in the United States and Canada

Status of North American Graduate Programs in Periodontics Providing Laser Education and Clinical Training: A Cross-Sectional Survey

The aim of this cross-sectional study was to evaluate the status of laser use and training in the U.S. and Canadian graduate periodontology programs. A survey questionnaire was sent electronically to 55 periodontology program directors in North America. The questions focused on laser implementation, types of lasers used, for which procedures lasers were used, and level of education/clinical training provided to residents. Data were analyzed using descriptive statistics and Fisher’s exact test. Twenty-two directors responded (40%). Most programs (86%) used lasers and 89% used a diode laser. Laser treatment was the most used for periimplantitis (84%). Fifteen programs (79%) provided didactic and clinical training, with 47% programs giving 4–12 h of didactic training. In 53% of programs, residents completed 4 to10 procedures. Only 29% of programs had residents who had received a certification in lasers, with most (80%) programs requiring between 1–9 cases for certification. Of the participants not providing laser training, the major barrier was indicated as being “expense”, with 68.7% reporting plans to implement laser education. Conclusions: Most graduate periodontics programs were providing laser training and treatment. There was great variability regarding the training methods, specifically in number of dedicated laser courses, time allocated for laser training, and prerequisites for laser certification.

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

INTRODUCTION

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.

MATERIALS AND METHODS

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.

RESULTS

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.

CONCLUSIONS

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.
