What type of adhesives are used for direct bonding?

Direct bonding in dentistry involves the use of adhesives that can be categorized into several types based on their curing mechanisms. The correct answer identifies that chemical-only adhesives, light cure adhesives, and dual cure adhesives can all be used for direct bonding procedures.

Chemical adhesives are activated through a chemical reaction, allowing for bonding without any light activation. Light-cure adhesives require exposure to a specific wavelength of light, typically from a dental curing light, to initiate the setting process. Dual-cure adhesives combine both chemical and light activation, offering versatility and ensuring optimal bonding in various conditions, particularly in areas that may be challenging to light cure thoroughly.

Using a combination of these adhesive types allows dentists to select the most suitable option depending on the clinical situation, including the materials being used and the specific requirements of the bonding procedure. Each type of adhesive serves unique purposes, contributing to effective and reliable bonding for direct restorations, such as composite resins, brackets, and other dental appliances.
