» Influence of irrigants on the coronal microleakage of laterally condensed gutta-percha root fillings
By JofER editor | Published 09/19/2008 | Endodontic Articles 10 | Unrated
N.Vivacqua-Gomes, C. C. R. Ferraz, B. P. F. A. Gomes, A. A. Zaia, F. B.Teixeira & F. J. Souza-Filho
School of Dentistry of Piracicaba, University of Campinas, Piracicaba, Brazil.

Aim.
To assess in vitro coronal microleakage in extracted human teeth after root-canal treatment, using different endodontic irrigants.

Conclusions.
Under the condition of this study, irrigation method during root-canal treatment influenced coronal microleakage. NaOCl + EDTA and chlorhexidine gel allowed better sealing following root filling.
» Periapical changes following root-canal treatment observed 20-27 years postoperatively
By JofER editor | Published 09/19/2008 | Endodontic Articles 10 | Unrated
O. Molven, A. Halse, I. Fristad & D. MacDonald-Jankowski
Department of Odontology - Endodontics, Radiology, School of Dentistry, University of Bergen, Norway.

Aim.
The aim of the present study was to identify periapical changes 20-27 years after root-canal treatment.

Conclusions.
Late periapical changes in roots treated endodontically, with more successes than failures, were observed radiographically more than 10 years after treatment. The healing processes in most of the successful cases appeared to be disturbed and delayed by extension of root-filling material into the periapical area. Small radiolucencies around surplus material should not be misinterpreted as failures. Failures many years after treatment are most likely to be due to infection.
» Evaluation of healing with use of an internal matrix to repair furcation perforations
By JofER editor | Published 09/18/2008 | Endodontic Articles 10 | Unrated
M. Rafter,M. Baker, M. Alves, J. Daniel & N. Remeikis
University of Illinois at Chicago, Chicago, IL, USA.

Aim.
The purpose of this study was to evaluate healing responses following repair of furcation perforations, with and without an internal matrix. Two matrix materials, HAPSET (65% non-resorbable hydroxyapatite and 35% plaster of paris) and hydroxyapatite were compared.

Conclusions.
Within this animal model healing responses are better when an internal matrix, whether HAPSET or hydroxyapatite, is used in the repair of furcation perforations.
» Calcium sulphate as a bone substitute for various osseous defects in conjunction with apicectomy
By JofER editor | Published 09/17/2008 | Endodontic Articles 10 | Unrated
Y. Murashima, G. Yoshikawa, R.Wadachi, N. Sawada & H. Suda
Department of Restorative Sciences, Graduate School, Tokyo Medical and Dental University, Tokyo, Japan.

Aim.
The purpose of this study was to investigate the effect of calcium sulphate on various osseous defects when used in conjunction with apicectomy.

Conclusions.
In this study, the use of calciumsulphate was effective for bone regeneration in large osseous defects and ‘through and through’osseous defects but not in osseous defects communicating with the gingival sulcus. This study suggests that bone regeneration after apicectomy might be accelerated through the use of calcium sulphate filling.
» A survey of endodontic practice amongst Flemish dentists
By JofER editor | Published 09/15/2008 | Endodontic Articles 10 | Unrated
G. Slaus & P. Bottenberg
Department of Endodontics, and Department of Restorative Dentistry, Free University of Brussels, Brussels, Belgium.

Aim.
The purpose of this study was to gather information on routine endodontic treatment performed by Flemish (Dutch-speaking Belgian) dentists.

Conclusions.
This study showed that endodontic procedures in general practice and quality guidelines differ, especially in the low use of rubber dam, the frequent use of phenolic compounds and para-formaldehyde-containing disinfectants and the low frequency of detecting and filling a fourth canal in maxillary first molars. Despite a variety of new instruments and techniques, most GDPs used conventional preparation and obturation techniques. Endodontic treatment is still considered to be a tedious procedure. Owing to the lack of endodontic specialists, most GDPs reported performing re-treatments themselves.
