Abstract

This paper was undertaken to study the use of Cavit an[sic] an endodontic filling material.

Part I examines the physical and biological properties of Cavit. This material has a 14% linear setting expansion, which results in a very tight interphase seal. It is theorized that this type of seal in connection with a three dimensional obturation is necessary to prevent the flow of irritant from the oral environment to the periapical tissue.

The biological properties are tentatively shown to be similar to ZOE.

A description of the use of Cavit in various clinical situations is included.

Part II is a preliminary report on the efficacy of Cavit in a clinical situation. 762 teeth were examined at an average recall time of 7.2 months. Success and failure were judged solely on radiographic data. The overall success rate reported is 93.5%. The effect of overfilling and underfilling on success is examined. In vital teeth there was no difference in success (96.2% overfilling vs. 96.4% underfilling). However, in non-vital teeth there was a significant difference in success (93,1% underfilling vs. 84.3% overfilling). This trend is shown to be similar to previous published work on other filling methods.
