behandlingsadhesjon

Behandlingsadhesjon is a term used in Norwegian to describe adhesion that arises in connection with a treatment. The concept encompasses both the bonding of materials to biological tissue during medical or dental procedures and the formation of tissue adhesions after surgery. In materials science it can also refer to the adhesion between a treated surface and an applied coating or adhesive.

In dentistry, behandlingsadhesjon refers to bonding of restorative materials to tooth structure. This includes the use of primers, adhesive systems and cements to attach composites, ceramics or indirect restorations to enamel and dentin. Protocols differ: total-etch systems require etching with phosphoric acid, while self-etch systems combine conditioning and bonding. Success depends on clean, dry or controlled-moisture surfaces, proper polymerization and avoidance of contamination. Common failure modes involve interfacial degradation, incomplete resin infiltration and hydrolytic breakdown of adhesives.

In the medical and surgical context, the term also covers tissue adhesives used to join surfaces or seal wounds, such as fibrin sealants or medical-grade cyanoacrylates. Conversely, postoperative or post-traumatic adhesions can form between tissues, sometimes causing pain, obstruction or reduced mobility. These adhesions reflect the body's healing response and may require prevention strategies or surgical intervention.

Assessment of bond strength in dentistry uses tests like microtensile or shear tests; clinical performance is tracked through longevity of restorations and incidence of marginal leakage. In surgery, prevention of unwanted adhesions involves careful surgical technique, use of barrier films or anti-adhesion agents, and minimizing tissue handling.
