In vitro fracture resistance of endodontically treated anterior teeth with varying ferrule heights and configurations with glass-fiber post / 实用口腔医学杂志

ABSTRACT

The extracted human maxillary central incisors were endodontically treated and restored with glass-fiber post. Then they were randomly divided into four groups and tested. Results showed that groups with ferrule more than 2 mm had higher fracture resistence than others.
