How many years after eruption is root formation complete in primary dentition
1 - 1.5 years
The primary dentition is usually complete after how many years
3 years
Defects with the permanent dentition are congenital or developmental?
Developmental because calcification of permanent teeth takes place at birth/post birth

Eruption of the 6s
6 years
Eruption of the 7s
12-13 years
Eruption of the 8s
16+ years
After how many years is the root formation complete, post eruption for permanent teeth?
2-3 years
What is the grubby score
A simple visual method of demonstrating tooth-brushing performance, both absolute and dynamically overtime
Non fluoride methods of caries prevention
- Diet modification
- Oral hygiene and dental health education
- Fissure sealants
- sugar free medicines
- chewing gum
- chlorhexidine
Which type of sugars cause caries?
Non-milk extrinsic sugars e,g, table/recipe sugar, honey, fruit juices
Caries is positively related to the frequency of intake of non-extrinsic milk sugars
What is the maximum sugar attacks that you should have a day?
4 - Vipeholm study
Examples of non-cariogenic, non-sugar sweetners
xylitol, mannitol, sorbitol, maltitol
What is a fissure sealant
A material that is placed in the pits and fissures of teeth in order to prevent caries
if occlusal caries affects one permanent molar, the other permanent molars should be sealed
Which are the main teeth that are fissure sealed?
- 1st permanent molars
- Palatal pits of permanent lateral incisors
- 2nd permanent molars and all premolars
Types of sealants
- Resin
- GIC
- Compomer
- Fluoride containing sealants
