Numerous compounds have been used as root-end filling materials. Based on the results of
in vitro and intraosseous implantation tests, mineral trioxide aggregate (MTA) seems to have …

The histologic response to intentional perforation in the furcations of 28 mandibular
premolars in seven dogs was investigated. In half the teeth, the perforations were repaired …

Background It is essential to subculture the cells once cultured cells reach confluence. For
this, trypsin is frequently applied to dissociate adhesive cells from the substratum. However, …

Secondary electron emission materials are reviewed with the aim of providing guidelines for
the future development of novel transmission dynodes. Materials with reflection secondary …

We investigate Ore extensions of Baer rings and pp-rings. Let α be an endomorphism and δ
an α-derivation of a ring R. Assume that R is an α-rigid ring. Then (1) R is a Baer ring if and …

In vitro sealing ability and biocompatibility tests on mineral trioxide aggregate (MTA) have
shown similar or better properties for this material than for existing root-end filling substances. …

In this paper, we introduce a new high-resolution reflectometry technique that operates
simultaneously in both the time and frequency domains. The approach rests upon time-frequency …

This study was conducted to evaluate the pulpal response to direct capping with either mineral
trioxide aggregate (MTA) or calcium hydroxide (CH) cement in humans, with a focus on …

For a ring endomorphism α, we introduce α-skew Armendariz rings which are a generalization
of α-rigid rings and Armendariz rings, and investigate their properties. Moreover, we study …

OBJECTIVE: This study aimed at evaluating the radiopacity and cytotoxicity of Portland
cements containing bismuth oxide (PcBo) in varying ratios. STUDY DESIGN: Specimens …
