clinical skills for management of carious lesions in the permanent dentition

caries management can be viewed as a process of ...

recognition, re orientation, remineralisation, repair and review

1 of 13

how much fluoride does topical fluoride varnish contain and how much quantity can be given to patients

22600 ppm fluoride. 0.25ml= 2-5years 0.40ml= over 6. years old

2 of 13

fluoride application is contraindicated for:

Patients with an allergy to colophony. • Patients with ulcerative gingivitis/stomatitis. • Patients who have been hospitalised due to severe asthma or allergy

what is the procedure for placing topical fluoride varnish

1. Inspect the tooth under direct vision or indirectly with a mirror, depending on the location of the tooth- clean and dry. 2.If plaque/food particles are evident, clean with a toothbrush. Isolate the teeth and achieve moisture control.

continued

Use a microbrush to apply fluoride varnish to the contact points first. 5.Apply fluoride to the occlusal surfaces next. Advise the patient to avoid eating and drinking for 30 minutes after application and to avoid brushing the teeth for at least 4 hr

what can be used to introduce glass ionomer onto the. fissure pattern

blunt ended instrument such as a flat plastic, or ball ended probe, or directly if using capsular glass ionomer.

6 of 13

what is placed on top of the glass ionomer sealant on the. tooth.

petroleum jelly on the occlusal surface as a barrier against moisture, covering the entire sealant

7 of 13

what are the circumstances where carious lesions might be. sealed in

Clinically, the tooth has a non cavitated occlusal surface.

8 of 13

what does fluoride do

Inhibits demineralization, slowing decay. • Makes enamel more resistant to erosion. • In high concentrations, can inhibit bacterial metabolism/ enzyme activity.

9 of 13

when. does demineralisation occur

when there is an imbalance between mineral loss and gain.

10 of 13

what is a toxic dose of fluoride

5mg per kg

11 of 13

what are fissure sealant

protective plastic coating which is applied by a dentist to the biting surfaces of the back teeth, forming a hard shield that keeps food and bacteria from getting into the tiny grooves in the teeth and causing decay.

12 of 13

when are glass ionomers sealants indicated

Cooperation is insufficient for resin based sealant application. • There is insufficient moisture control. • A tooth is partially erupted.
