NaOCl
Pronunciation: N-A-O-C-L (spell out) or sodium hypochlorite
Also written as: NaOCl — Sodium Hypochlorite
The chemical abbreviation for sodium hypochlorite, the principal irrigant used in root canal treatment for its antimicrobial and tissue-dissolving properties.
Full Definition
Sodium hypochlorite (NaOCl) is widely regarded as the gold-standard root canal irrigant due to its capacity to dissolve organic tissue, eliminate bacteria, and disrupt biofilms. It is used in concentrations typically ranging from 1% to 6% during chemo-mechanical preparation of the root canal system. The abbreviation NaOCl is standard in endodontic literature and clinical protocols; editors should recognise it as a chemical formula rather than a trade name. Errors in concentration transcription are clinically significant; editors must ensure numerical values accompanying NaOCl are accurately reproduced. It is distinct from chlorhexidine, another commonly used irrigant with different properties.
Usage
Usage note: Render as 'NaOCl' in chemical and clinical contexts; always include the concentration percentage; do not abbreviate further.
