Several materials and lights are actually used for oral treatments. Their interactions with oral tissues can induce, produce, or provoke biological effects that could be appreciated or unwished. The knowledge of their process of interaction is necessary to improve the quality of treatments to avoid side effects.

Importantly, several matters are proposed for oral treatments in different fields of dentistry. The understanding of their effects on biological material can improve or prohibit their applications (e.g., bioactivation, biomodulation, magnetic properties, mechanical properties, chemical properties, and tissue overheating). Thus, studies focused on light or matters used in oral treatments and fundamental studies can enlighten on the interaction process with biological oral tissues and by the way improve the quality of oral treatments. In the oral environment, there are both hard (bone and teeth) and soft (gingival and mucosal tissues) ones, providing complex functions and aesthetics. Treatment modalities including matters or lights should specifically target these tissues for the best biological responses and clinical outcomes. Thus, fundamental research and clinical studies focused on the various oral tissues would enlighten the biological and interactive mechanisms that can eventually improve the quality of treatment for oral conditions and needs.

Potential topics include, but are not limited to:

• Oral light applications
• Oral pathologies
• Oral treatments applications
• Lasers and lights interactions with biological oral tissues
• Clinical applications using a new material
• Interaction between materials and oral tissues
• Basic research including molecular biology
• Stem cell research in dentistry
• Tissue regeneration in dentistry
• Bioactive molecules to stimulate dental pulp healing or dentinal bridging
• Biointeractive mechanisms—wavelengths, parameters, and indications
• Clinical studies of such applications
• New materials and advantages
• Limitations and risks
