Tissue dissolution

Tissue dissolution is not a discrete molecular target such as a receptor or enzyme, but rather a therapeutic process or desired clinical outcome involving the breakdown and removal of biological tissues. It is a cornerstone of endodontic therapy, where chemical irrigants like sodium hypochlorite are used to dissolve organic pulp remnants and necrotic debris to ensure thorough disinfection of the root canal system [1][3]. Beyond dentistry, enzymatic tissue dissolution is utilized in treating fibrotic disorders such as Dupuytren's contracture and Peyronie's disease, where collagenases are injected to selectively degrade pathological collagen deposits [12][14]. The mechanism of action varies by agent, involving nonspecific chemical processes like saponification and chloramination for bleach-based irrigants, or site-specific proteolytic cleavage for enzymatic debriding agents [8][12]. While highly effective for clearing infection sites or reducing fibrotic tissue, the lack of inherent specificity in many dissolving agents poses significant safety risks, including chemical burns or damage to surrounding healthy tissue if not carefully controlled [10][13].
