As a dental professional there is a requirement for precision, focus and unorthodox body positions. This combination may lead to prolonged sitting and standing positions in … Read more

As far back as 1967, Herb Schilder recognized that long-term endodontic success could approach 100%.1 For necrotic teeth, years of studies have demonstrated that success rates are usually lower.2 Cleaning and shaping a canal filled with bacteria would appear to pose a greater threat to success than simply having to remove inflamed tissue. So what … Read more
