A clinical trial of a light activated bonding material over an 18 month period.
Heliosit-orthodontic, a visible light cured adhesive, has been compared with Right-on, a chemically activated adhesive, on 122 patients for a mean period of 12 months with a range 3-18 months. The overall bond failure rate was 20 per cent. Heliosit-orthodontic had a 23 per cent failure rate compared with a 16 per cent failure rate for Right-on. Heliosit-orthodontic performed less well on the posterior teeth particularly lower second premolars (P less than 0.01). Both materials performed equally well in the labial segment.
