A Comparison of the Effects of Prophylaxis Pastes on In Vitro Laser Fluorescence Caries Detection Measurements

It was the aim of this study to examine the effects of cleaning with prophylaxis pastes/powder and toothpaste on the DD readings of teeth with dentinal caries. A total of 42 extracted molar teeth were used in this study. All teeth selected had a light fluorescent DDV reading of 18 at one occlusal site. Teeth were randomly distributed into 6 groups (Nupro-Denstply, Topex-SultanHealthcare, Enamel Pro-Premier Dental Products, Alpha Pro-Dental Technologies, Total 12-Colgate, PROPHYpearls-KaVo). After obtaining baseline readings, pastes/powder and tooth paste were applied, tooth surfaces were rinsed with water using a air/water syringe for 3 s, and DD measurements were taken. Rinsing was performed for an additional 3 s, and DD measurements were repeated. The lowest DDV was observed in Nupro and PROPHYpearls group, which were not significantly different from each other in all time intervals. When comparing of rinsing time, there was statistically significantly difference between DDV of Topex, Enamel Pro, Alpha Pro, Total 12 groups at 0-3, 0-6 s time intervals and between DDV of Enamel Pro, Alpha Pro, Total 12 groups at 3-6 s time intervals. When using the laser fluorescence method dentists must take into account that there are potential factors that can change the readings. Prophylactic products used in practice and in home care could interfere with DDV.
