No area of treatment in pediatric dentistry has been more controversial than pulp therapy. In particular, the vital pulpotomy procedure has been a topic of debate for decades. While pulpotomy therapy evolved slowly over the first 40 years, the pace of change since the 1960s has continued to accelerate. This book is a review and prospectus of this field, presented in the context of the rationales that have guided development of new and very divergent treatment modalities. While there have been many excellent reviews of pulp therapy .in recent years, 1~ none has presented a framework for the systematic analysis of past developments or future trends.
