Adhesive dentistry is a branch of dentistry which mainly deals with adhesion or bonding of the adhesive material or cements to the natural substance of teeth,enamel and dentin.Dental bonding is a dental procedure in which a dentist applies a tooth-colored resin material (a durable plastic material) and hardens it with a special light. This ultimately "bonds" the material to the tooth and improves the overall appearance of teeth.[citation needed] Tooth bonding techniques have various clinical applications including operative dentistry
and preventive dentistry as well as esthetic and pediatric dentistry, prosthodontics, and orthodontics. As a modern science, adhesive
dentistry studies the nature and strength of the adhesion to dental hard tissues, properties of adhesive materials, causes and mechanisms of failure of the bonds, clinical techniques for bonding and newer applications for bonding such as bonding to the soft tissue.[1] There's also direct composite bonding which uses tooth-colored direct dental composites to repair
various tooth damages such as cracks or gaps.
