Risk indicators for marginal bone resorption around implants in function for at least 4 years: A retrospective longitudinal study.

Background: Marginal bone stability is considered one of the most important issues in implant dentistry. It is essential to understand how various factors influence bone resorption around implants. The purpose of this retrospective longitudinal study was to identify potential risk indicators associated with marginal bone resorption around implants in function for at least 4 years.

The relationship between the bone characters obtained by CBCT and primary stability of the implants.

Background: The aim of this study is to investigate the correlation between the thickness of the cortical bone or the voxel values that are obtained by cone beam CT (CBCT) and the insertion torque values (ITVs) or the implant stability quotient (ISQ) values.

Methods: A pig's ilium was used as the implant placement site. The implants used in this study were two kinds of diameters (3.

Effect of adding impression material to mandibular denture space in Piezography.

The purpose of the study was to examine the effect of adding impression material on denture space using a piezographical record. Subjects were ten voluntary edentulous patients, aged from 61 to 84 years old. A maxillary trial denture with anterior artificial teeth and a mandibular base plate with a keel were inserted into the oral cavity.

[Historical and herbological investigation of Yinchenhao].

The description of "Yinchenhao" in Chinese and Japanese medical and pharmaceutical literature, Bencao, was historically examined.Yinchenhao was consistently considered an indispensable medicine for treating jaundice. It was estimated that in China, a shrubby Artemisia plant just like the Artemisia capillaris, or a related plant, was utilized as Yinchenhao in the Liuchao and Song dynasties.

[A common antigenic epitope in influenza A virus (H1, H2, H5, H6) hemagglutinin].

Avian influenza A viruses belonging to hemagglutinin (HA) subtypes H5 and H6 were studied in the infectivity neutralization test and radioimmunoprecipitation assay (RIPA) with monoclonal antibody MAb C179. This MAb recognizes a conformational antigenic epitope in the stem region of HA formed by two regions (amino acid positions 318-322 in HA1 subunit and 47-58 in HA2), conserved in all H1 and H2 influenza viruses. MAb C179 reacts with HA of H5 viruses in RIPA and neutralizes these strains as efficiently as H2 viruses.
