Marginal bacterial leakage and pulp reactions in Class II composite resin restorations in vivo.

• The presence of stainable bacteria under restorations and pulp reactions in 36 teeth restored in vivo with a modified Class II composite resin restoration with two different dentine treatment techniques were studied on three separate follow-up occasions (1-3, 7-10 and 28-32 days). Half of the cavities showed stainable bacteria at the cavity margins and bottoms. Teeth restored with method A (Gluma/Occlusin) showed significantly fewer restorations with stainable bacteria then teeth restored with method B (Life/Occlusin) (p less than 0.05). Significantly more restorations with detectable bacteria were found after 28-32 days and restorative method B (p less than 0.05). There were no differences in occurrence and grade of pulp inflammation for the different dentine treatment techniques and time periods.
