Summary

Mirrorless and smartphone cameras can accurately profile dental light-curing units (LCUs), correlating well with professional systems. While not as precise as dedicated equipment, these accessible cameras offer a viable alternative for assessing LCU beam profiles.

Area of Science:

  • Dental materials science
  • Optical engineering
  • Medical imaging

Background:

  • Dental light-curing units (LCUs) are crucial for polymerizing dental materials.
  • Accurate assessment of LCU beam profiles is essential for effective light delivery and clinical success.
  • Traditional beam profiling systems can be expensive and complex.

Purpose of the Study:

  • To evaluate the feasibility of using mirrorless and smartphone cameras for dental LCU beam profiling.
  • To compare the results obtained from consumer cameras with a standard camera-based laser beam profiling system.
  • To determine the correlation between irradiance distribution captured by different camera types.

Main Methods:

  • Three dental LCUs were tested, measuring their spectral power with a spectrophotometer.
  • Light emissions were projected onto a diffuser and captured by a mirrorless camera, a smartphone, and a professional beam profiler.
  • Image calibration involved bandpass optical filters and integration of total spectral power output; statistical analysis used digital image correlation.

Main Results:

  • Beam profile images revealed non-uniform radiant emittance and spectral emission distributions for all tested LCUs.
  • A strong positive correlation was observed between the irradiance distributions captured by the mirrorless camera (Pearson's r = 0.91) and the smartphone (Pearson's r = 0.88) compared to the professional system.
  • Confidence intervals indicated high reliability in the correlation results for both consumer camera types.

Conclusions:

  • While a standard Ophir beam profiling system offers the highest accuracy, mirrorless and smartphone cameras demonstrate a strong correlation in irradiance distribution.
  • These alternative cameras provide a practical and accessible method for dental LCU beam profiling.
  • Users must exercise caution, considering sensor type, image bit depth, and processing methods for accurate results.
