¤ Effervescent action has two benefits
¤ One – the bubbling of soln when in contact with tissues will form debris – which is easier
to identify & thus clean out.
¤ Two - Anti microbial – the liberation of oxygen will kill the strictly anaerobic organisms
¤ Used alternatively with NaOCl.
3. CHLORHEXIDINE
¤ Daily use mouthwash – 0.12%
¤ Perio cases / gingivitis cases – 0.2%
¤ RCT cases as irrigant – 2% - highest conc.
¤ Advantages
- Anti-microbial property
- Substantivity*
¤ Disadvantage
- Stain causing
- Chance of occlude / obstruct salivary gland mainly Stenson’s duct (parotid )
- Metallic taste
- Caution – never mix CHX + NaOCl –CARCINOGENIC – dangerous & contraindicated (So how we use is after full saline irrigation – last u do CHX maybe.)
