Frédéric Bukiet

Prof. Bukiet graduated from Aix-Marseille University in 1998. He obtained his Master's Degree and started a private practice limited to Endodontics in Marseille. Prof. Bukiet works presently full-time as teacher, researcher and hospital clinician at Aix-Marseille University. His research activity allowed him to earn his PhD in 2014 at the University of Montpellier then his accreditation to supervise research at Aix Marseille University. 

Frédéric Bukiet is currently the Head of Department of Endodontics at Aix-Marseille University. He is also director of the Postgraduate Endodontic Program with Dr Ludovic Pommel. He has published numerous papers in national and international journals and given around 150 lectures worldwide.

He was a certified member and board member of the French Endodontic society. He is currently a guest member of the European Society of Endodontology and a member and the secretary of the French College of Teachers in Conservative Dentistry and Endodontics. He is moderator of the online endodontic educational forum Endolit and member of the clinical advisory board. He serves as a peer reviewer for different journals (Clinical Oral Investigations, European Endodontic Journal, European Journal of Dental Education, Scanning) and is also Associate Editor of the European Endodontic Journal.

Calcium Silicate-Based Root Canal Sealers for Obturation of the Root Canal Space: A Recent Approach Raising New Questions

Several obturation techniques combining gutta-percha and a root canal sealer have been used to seal the root canal space including the single cone technique. This technique relies primarily on one gutta-percha cone and more emphasis is placed on the sealer which functions as a root canal filler. Among the available root filling techniques, single cone technique is often considered to be less technique-sensitive as well as cost-effective. However, a higher sealer volume inside the root canal space may negatively influence the seal as most available sealers tend to shrink upon setting. As a result, SCT combined with conventional sealers was deemed inappropriate, and it was recommended to maximize the gutta percha volume and minimize the sealer thickness. Recently, hydraulic calcium silicate-based sealers, also known as bioceramic root canal sealers, have been introduced. These sealers have good flowability and antimicrobial properties. The material itself is also hydrophilic, thus it can expand when contacting moisture, form a hydroxyapatite, and bond to dentin resulting in better sealing. Due to these improved properties, bioceramic root canal sealers have been recommended by the manufacturers to be incorporated in root canal obturation using a single cone technique. Given the increasing bioceramic root canal sealers release into the market, this lecture aims to examine the current knowledge and the clinical application of these materials for obturation of the root canal space.

Contemporary Endodontics: Current Strategies and Perspectives

In the past 10 years, considerable technological evolutions have been proposed to enhance root canal treatment quality, to make the latter less operator dependent and more reproducible. The goal of this lecture is to provide a critical overview of the following developments:

• CBCT use in Endodontic has revolutionized the preoperative evaluation of complex cases leading to better appreciate the tridimensional anatomy and to anticipate potential clinical difficulties. Currently, the CBCT images can be used with different software only selecting the tooth of interest, providing a tridimensional rendering and allowing a treatment plan.
• Conservative and ultraconservative access cavities have been proposed to decrease the loss of dental structures and the risk of fracture. This controversial topic needs clarification especially regarding the benefit/risk balance of such strategies.
• Nowadays, a lot of shaping systems are available in the market. Reciprocating single files have been recommended to improve the cyclic fatigue resistance and to avoid the screwing effect. Heat treatments of nickel-titanium files also contribute to increase their mechanical properties and their flexibility. Finally, new file design has been recently released aiming to improve the cleaning outcome. The main evolutions on root canal instrumentation will be discussed comparing the reciprocating movement and the continuous rotation.
• Due to their improved properties, bioceramic root canal sealers have been recommended to be used with the “single cone technique”. the clinical application of these materials for obturation of the root canal space will also be discussed.
