Objectives To evaluate the safety and effectiveness of the plasma pencil ( PP ) device in conjunction with H 2 O 2 gel. The purpose of this study was to determine whether LTAPP delivered using the PP would enhance the tooth‐whitening process while causing no thermal threat. Methods The study consisted of thirty extracted human teeth that were randomized into two groups: Group I received LTAPP plus 36% H 2 O 2 gel at 10, 15 and 20 min and Group II received 36% H 2 O 2 gel only at the same time intervals. Tooth surface temperature was measured periodically throughout the experiment using a non‐contact thermometer. Digital photographs were taken pre‐ and post‐treatment and transferred to A dobe P hotoshop for comparison, using the CIELAB C olor V alue S ystem. Only L * (lightness) values were evaluated in this study. Data were analysed using descriptive statistics and t‐ test at the 0.05 level. Results The results revealed a statistically significant difference in mean CIE L* values after exposure to LTAPP plus 36% H 2 O 2 gel, compared with 36% H 2 O 2 only, in the 10‐ and 20‐min groups ( P = 0.0003 and 0.0103, respectively). The temperature in both treatment groups remained under 80°F throughout the study, which is below the thermal threat for vital tooth bleaching. Conclusion Utilizing PP device in conjunction with 36% H 2 O 2 safely accelerates and enhances the tooth‐whitening process.
