| Methods |
Controlled clinical trial conducted as a hospital‐based study in the UK. Split‐mouth design. Blinding of treatment allocation unclear. Withdrawals not mentioned. Analysis appears to be based on all recruited cases. |
| Participants |
n = 45 patients. Age range 13.7 to 15.5 years, consecutively approached to take part in trial. |
| Interventions |
2 groups compared:
1. no mix composite (Right on)
2. light cured compomer (Dyract Ortho). |
| Outcomes |
1. Bond failure.
2. Decalcification of upper and lower incisors and canines. |
| Notes |
Alternate randomisation method used to allocate patients. Inclusion/exclusion criteria unclear. Groups treated identically apart from named intervention. Statistics: paired log rank tests and Cox proportional hazards model. Data not amenable for MetaView. |
