Does chewing chitosan-containing gum effectively inhibit the growth of cariogenic bacteria?
These findings suggest that a supplementation of chitosan to gum is an effective method for controlling the number of cariogenic bacteria in situations where it is difficult to brush one's teeth, such as when an individual is away from home all day or participating in outdoor training.
General practices within areas of deprivation were more likely to refer patients to exercise referral schemes than practices in more advantaged areas. Once referred, it was found that patients living in areas of deprivation were as likely to take up and to complete the scheme as those living in more advantaged locations. Research is needed to identify the organisational and contextual factors that allow this pattern of service delivery, which appears to facilitate access to care among patients who live in areas of deprivation.
