Abstract
Theobromine (Th) was documented during the last decades for its important role in the prevention of dental caries, having this role dueto its antibacterial action against the Streptococcus mutants and S. sanguinis, thus reducing the formation of dental biofilm on the teeth surface. Thermally induced interactions of theobromine in 1:1 mass ration bynary mixture with different types of Poly(methyl methacrylate) based materials and the induced interactions between Poly(methyl metha-crylate) based materials and HA were performed using thermal analysis and FTIR spectroscopy. This study aims to be a preliminary study for various mixtures of HA/methacrylate-based materials and Th with usage in dental applications. The instrumental techniques used can be successfully applied in the characterization of dental materials and can lead to conclusions on how to use them.Studies have led to the conclusion that Th can be used for the treatment of early decay by incorporation into the polymer material. It is recommended to use these materials as successive layers (Th with HA and after that dental material).
Highlights
Poly(methyl methacrylate) has been commonly usedin dentistry and many other fields. poly(methyl methacrylate) (PMMA) is generally referred to as a synthetic resin and is usually produced by polymerization of the methyl-methacrylate monomer [1]
The most commonly used materials in dentistry based on methacrylate are 2,2-bis[p-(2`hydroxy-3`-methacryloxypropoxy)phenylene]propane (Bis-GMA) and 1,6-bis(methacryloxy-2-ethoxycarb-onylamino)-2,4,4-trimethylhexane (UDMA) (See structure of Bis-GMA and UDMA in Figure 1 and 2)
UDMA is used for lower viscosity and for possibility of forming strong hydrogen bonds due to urethane linkage

Poly(methyl methacrylate) has been commonly usedin dentistry and many other fields. Poly(methyl methacrylate) (PMMA) is generally referred to as a synthetic resin and is usually produced by polymerization of the methyl-methacrylate monomer [1]. PMMA is widely used in the dental field, especially due to its biocompatibility, followed by resistance to humidity and weathering, acceptable aesthetics, low cost, easy processing, good flexibility and, for lofty surface resistance [2,3]. The most commonly used materials in dentistry based on methacrylate are 2,2-bis[p-(2`hydroxy-3`-methacryloxypropoxy)phenylene]propane (Bis-GMA) and 1,6-bis(methacryloxy-2-ethoxycarb-onylamino)-2,4,4-trimethylhexane (UDMA) (See structure of Bis-GMA and UDMA in Figure 1 and 2). UDMA is used for lower viscosity and for possibility of forming strong hydrogen bonds due to urethane linkage. These hydrogen bonds play an important role in the durability of the composite’s matrix [8]
