From Pentron and J. Blank: "Reliably bonding direct and indirect restorations to both enamel and dentin is the single most important scientific discipline in modern dentistry. Over the past 18 years, adhesion has increased in effectiveness and predictability, but in turn has become complex and confusing. This CE presentation will address proper product selection, proper use of products and the variables that control the post-operative outcome."

Mineral Trioxide Aggregate (MTA) and direct pulp capping
A large clinical trial was conducted between 2001 and 2006 at Ruprecht-Karls-University of Heidelberg, Germany (1). Direct pulp capping with either MTA or Calcium hydroxide was done in 167 teeth of 149 patients. Treatment outcome was evaluated clinically and radiographically by calibrated examiners 12-80 months post-treatment. The authors reported a high recall rate of more than 70% and based the statistical analysis on 108 patients and 122 treated teeth. A significantly greater success rate was found for MTA (78% of teeth) than Calcium hydroxide (60% of teeth). It seems critical to restore such teeth permanently as soon as possible after pulp capping. This study showed that teeth permanently restored ≥2 days after capping had a significantly worse prognosis irrespective of the capping material. The authors concluded that "MTA appears to be more effective than calcium hydroxide for maintaining long-term pulp vitality after direct pulp capping".
Another study is an immunohistological study on Wistar rats (2). It compared the proliferation of pulp cells 1, 3, and 7 days after direct pulp capping with either MTA or Calcium hydroxide. After 3 days, the number of proliferating cells (fibroblasts, endothelial cells and Hoell's cells) was significantly greater when capping was performed irrespective of the material compared to the control group with no capping. After 7 days, however, there were no differences between MTA and Calcium hydroxide groups and the control group. The authors concluded that "Immunohistologic analysis demonstrated that MTA showed similar results when compared with Calcium hydroxide within the first week after direct pulp capping".
