flurodie mouthwash - 225ppm
fluoride gel - 12300ppm
What is the mechanism by which topical fluoride helps to prevent cavities
Slows down development of carious lesions by stopping demineralisation
It makes enamel more resistant to acid attack and speeds up remineralisation by the use of F- ions. it makes enamel stronger
Has an antimicrobial effect on plq (stops bacterial metabolism)
What is the fluoride tab for 4 year old at high risk caries who lives in area <0.3ppm flurodie in water supply

What is the rationale for use of antibiotics in chemo perio patient
Perio disease is mainly caused by bacteria (p. gingivalis)
Chemo patients are immunosuppressed therefore antibiotics needed to prevent bacterial infection of susceptible host
Invasion into perio tissues/dental tubules unable to be reached via mechanical means
What problems limit the usefulness of antibiotics in treatment of periodonitits
Antibiotic resistance
Allergic reaction
Reaching the targeted bacteria, pentrating the biofilm
What situations would it be apporpriate to prescribe systemic antibiotics
Patient is immunocompromised
Systemic symptoms present with aggressive periodontits
Aggresstive infection/perio abscess
On going disease despite mechanical therapy/good OH
Which part of the root canal filling is most important in ensuring long term sucess?
Coronal seal
Minimum data set that should be recorded onto the record block of maxillary complete denture
