Micro-invasive treatments can slow caries progression

8 trials involving a total of 365 patients were included in this Cochrane review of micro-invasive treatments for proximal caries. Micro-invasive treatment significantly reduced the odds of lesion progression compared with non-invasive treatment (e.g fluoride varnish) or oral hygiene advice (e.g to floss) OR=0.24, (95% CI; 0.14 to 0.41).
