Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
The treatment of peri-implant diseases: A new approach using hybenx® as a decontaminant for implant surface and oral tissues
No full textThe aim of the present study is to demonstrate the efficacy of HyBeNX® to decontaminate the implant surface, both in the case mucositis and severe peri-implantitis and to allow future bone regeneration
Clinical and histomorphometric outcome in future site development performed with a nano-hydroxyapatite through hydraulic sinus lift technique
No full textPurpose. The crestal sinus lifting by means of hydraulic technique associated with a nano-cristalline hydroxyapatite in an aqueous medium is investigated. Materials and methods. A specific purpose-made instrument is used, consisting of a syringe with a micrometrically controlled piston connected to a dispenser used to inject, in a calibrated and precise manner, noted volumes of graft material into the sub-schneiderian space. Adopting such a technique the Authors performed 7 future site developments, on 7 patients (2 males; 5 females; mean age 49.29±8.08 years), using a nanocrystalline hydroxyapatite. In the second stage, performed at 5.71±1.52 months, 7 implants were placed, after harvesting bone biopsies from the regenerated sites. The samples underwent histological and histomorphometric analysis. Results. The average percentage of vital bone was of 33.27±5.98%, while the bone marrow and graft material were 60.84±5.93% and 5.87±3.05%, respectively. Conclusions. The results confirm the effectiveness of this method in restoring bone volume in the sub-antral region. Furthermore nano-cristalline hydroxyapatite is a proper material for sinus floor augmentation
