Q
What are the indications that would mean you want to use SSCs on primary molar teeth
A
- 2 or more carious surfaces or extensive one surface caries
- Following pulp therapy of primary molar teeth
- Developmental problems (AI, DI, hypoplasia)
- Fractured primary molars
- Patients with high caries risk
- In GA patients undergoing restorative care if two or more surfaces involved
- As an abutment for certain appliances, space maintainers

Q
What are some contraindications of SSC use in primary molars
A
- If primary molar close to exfoliation with more than half the roots resorbed (radiograph)
- In patients with known nickel allergy or sensitivity
3
Q
Describe the procedure of preparing a primary molar to receive a SSC
A
- LA, preferably rubber dam
- Caries removal and appropriate pulp treatment
- Place mesial and distal wedges, gingival to contact areas to help protect tissues and reduce contamination
- Mesial and distal surfaces removed using fine tapered or diamond bur
- Cut through tooth contact points without damage to adjacent tooth, angle bur away from vertical so a shoulder isn’t created at the gingival margin
- Same bur or 330 bur can be used to reduce the occlusal surface to allow 1.5-2mm space between prepared tooth and its opposing dentition
- Try on crown and check crown is sitting within gingival crevice
- Crimp crown is seats on gingival crevice and re-try, if over-extended cut back the area using scissors/stone and smooth edges with stone or rubber wheel
- Wash and dry tooth with 3 in 1 before cementing on the crown using GIC based cement. Seat crown from lingual to buccal pressing down firmly
- Remove excess cement using wet gauze, floss and probe. - Check occlusion, if high remember the occlusion will adjust a little to accommodate this

Q
What is the Hall Technique
A
This is a method for managing carious primary molars where decay is sealed under preformed metal crowns, without LA, tooth preparation or any caries removal
