Bottom Line: In a further experiment, 10 samples of type I collagen membrane were used to evaluate the effects of Papacarie(TM) on the collagen microstructure.The results demonstrated that the application of Papacarie(TM) does not lead to the degradation of collagen and this product can be safely used in minimally invasive dentistry.As the integrity of sound collagen is preserved after the application of the papain-based gel, this product is indicated for the selective removal of infected dentin, leaving the affected dentin intact and capable of re-mineralization.

ABSTRACT
Considering the improvement of biomaterials that facilitate atraumatic restorative techniques in dentistry, a papain-based gel can be used in the chemomechanical removal of decayed dental tissue. However, there is no information regarding the influence of this gel on the structure of sound collagen. The aim of the present study was to investigate the adsorption of a papain-based gel (Papacarie(TM)) to collagen and determine collagen integrity after treatment. A pilot study was first performed with 10 samples of type I collagen membrane obtained from bovine Achilles deep tendon to compare the influence of hydration (Milli-Q water) on infrared bands of collagen. In a further experiment, 10 samples of type I collagen membrane were used to evaluate the effects of Papacarie(TM) on the collagen microstructure. All analyses were performed using the attenuated total reflectance technique of Fourier transform infrared (ATR-FTIR). The results demonstrated that the application of Papacarie(TM) does not lead to the degradation of collagen and this product can be safely used in minimally invasive dentistry. As the integrity of sound collagen is preserved after the application of the papain-based gel, this product is indicated for the selective removal of infected dentin, leaving the affected dentin intact and capable of re-mineralization.

Mentions: Figure 4 displays the mean infrared spectrum of PapacarieTM, showing corresponding infrared absorption bands of CO, COH, CC, NH and CH3. The figure also shows the mean infrared spectrum of collagen membranes treated with PapacarieTM, with increased absorbance of N-H and Amide A bands as well as a slight decrease in amide III absorbance. However, no new bands or the disappearance of bands were evident.
