The Role of the Blood Clot in Endodontic Therapy an Experimental

It was decided to study how the periodontal tissue would react if the entire pulp was removed froiii the main canal and the apical part subsequently allowed to fill with blood. The aim was primarily to see if the results would have any significance in clinical endodontics. At the same time one might expect that an experimental ...

Statistical and other methodological issues in the production of

production of reliable experimental endodontic research and why they matter. DONALD M. BRUNETTE. It has long been assumed that science is self- correcting and that lack of reproducibility or even fraud will be uncovered in subsequent attempts to replicate observations or experiments. Recent studies have cast doubt on.

Endodontic treatment of experimental root perforations in dog teeth

Abstraet - Experimental root perforations were made in 131 teeth of 5 mongrel dogs. The perforations were treated according lo five dilTerent endodontic teehniques and the results were ob- served after 3 weeks, 3 months and 1 year. The histologie reaetion was dominated by inflammation and downgrowth of gingival.


Antibacterial Effectiveness of Peracetic Acid and Conventional

This study evaluated the in vitro antibacterial activity of conventional and experimental endodontic irrigants against Enterococcus faecalis. The following substances were evaluated by direct contact test: 2.5% sodium hypochlorite ( NaOCl); 2% chlorhexidine (CHX);. 1% peracetic acid. After different contact periods (30 s, 1, 3, ...


Effect of photodynamic therapy (PDT) onEnterococcus

Conclusions. Photodynamic therapy killed E. faecalis in experimental primary endodontic infections and retreated human root canals. PDT is an effective supplement in root canal disinfection, especially in endodontic retreatments.
