Complex root canal systems create challenging conditions for the general dental practitioner. In this 9 part TubulesLive, Dr. Antonis Chaniotis goes through various aspects, discussing and demonstrating how to access, prepare, negotiate, irrigate and obturate complex root canal anatomy and how controlled memory files provide a massive benefit. Dr. Antonis Chaniotis provides some well-documented video of practical, real-life, live endodontic cases and provides excellent tips on how the clinician can improve their daily endodontic practice in all these areas. 

Controlled memory navigation of curved canals. Part 1 - Dr. Antonis Chaniotis

Aims and objectives:

  • Understand the navigation coordinates of internal anatomy of human teeth which are important for canal preparation
  • The role of rotary instrumentation width for shaping the root canal system
  • The role of instrument width on apical diameter during canal preparation

Controlled memory navigation of curved canals. Part 2 - Dr. Antonis Chaniotis

Aims and objectives:

Dr. Chaniotis discusses the role of the file length and the file design for preparation of the canals. He discusses the complications arising from preparing canals beyond the apex and the characteristics of root curvature.

  • Understand the in-depth focus on rotary instrumentation length for shaping the root canal system
  • The role of rotary instrumentation length for shaping the root canal system
  • The importance of the length of the preparation in canals
  • Understand the importance of file design in preparation of canals
  • Understand the complications arising from inappropriate choice of file design and length
  • Understand root canal curvature - the incidence of curvature, characteristics of curvatures especially in molar teeth, and the clinical relevance for successful root canal treatment
  • Understand mechanisms of rotary instrument fracture in curved canals
  • Understand how to choose the right rotary instrument to get a result which is safe, predictable and objective

Controlled memory navigation of curved canals. Part 3 - Dr. Antonis Chaniotis

Aims and objectives:

Endodontic complications include file separation, considered to be one of the highest causes for litigation in the UK. A large number of these occur in cases with curved canals. It is therefore important for the clinician to understand the characteristics of such canals. Dr. Chaniotis shows examples of how he managed cases with extreme curvature.

  • Understand the characteristics of curvature
  • Where maximum stress concentration for instruments would occur
  • The Hyflex rotary file system and the protocol of use for the file system
  • Understand the physics of rotary file structure

Controlled memory navigation of curved canals. Part 4 - Dr. Antonis Chaniotis

Aims and objectives:

When negotiating curved canals, having knowledge of the metal and file structure is useful. In this, part 4 of the series, Dr. Chaniotis gives an insight into the physics of the metals used for rotary files and the specific characteristics of the Hyflex file system that make it different. He explains how these characteristics translate to clinical practical applications.

  • Understand the physics of rotary file structure and what causes deformation in rotary files
  • The austenite and martensite structure and temperature
  • How the physics related to the Hyflex file help it to overcome challenges of difficult anatomy
  • Understand how safe memory and controlled memory files differ in curved canals with a practical demonstration

Controlled memory navigation of curved canals. Part 5 - Dr. Antonis Chaniotis

Aims and objectives:

In this, part 5 of the series, Dr. Chaniotis details his protocol for using the Hyflex files, discussing, through videos, S-shaped canals and tips on navigating such canals.

  • Understand the protocol for the Hyflex files
  • Observe clinical cases and gain tips on improving endodontic canal preparation, irrigation and obturation
  • Understand the implication of controlled memory files in S-shaped canals
  • Observe clinical cases and gain tips for endodontic preparation in S-shaped canals

Controlled memory navigation of curved canals. Part 6 - Dr. Antonis Chaniotis

Aims and objectives:

In this video, part 6 of the series, Dr. Chaniotis continues detailing examples of his cases and how he negotiates complex canal anatomy. He also discusses irrigation protocols, the importance of irrigation to maintain apical patency, keeping apical patency viable and how to make sodium hypochlorite more effective for irrigation, through demonstrating biosonic ultrasonic irrigation, in a clinical case. He then discusses access cavities, detailing the implications and applications of minimally invasive access cavities. Finishing with obturation and providing tips on obturation, including how to make the best use of Gutta flow.

  • Understand the impact of irrigation
  • Understand the factors that make irrigation more effective
  • Understand the use of biosonic ultrasonic irrigation
  • Understand the importance of maintaining apical patency
  • Understand the applications and implications of minimally invasive accessive cavities
  • Understand the tips of obturation using gutta percha and gutta flow
  • Understand how to make the best of gutta flow

Controlled memory navigation of curved canals. Part 7 - Dr. Antonis Chaniotis

Aims and objectives:

In the video, part 7 of the series. Dr. Chaniotis talks about obturation, demonstrating, through some excellent videos, complete clinical cases of access to preparation to obturation, for lower incisors, upper molars and premolars.

  • Learn some positive tips on irrigation
  • Learn some tips of obturation including “negative pressure obturation”

Controlled memory navigation of curved canals. Part 8 - Dr. Antonis Chaniotis

Aims and objectives:

In this video, part 8 of the series, Dr. Chaniotis provides a practical demonstration of preparation using rotary files, irrigation and obturation on glass blocks. Demonstrating how to use the Hyflex protocol for canal preparation, with curvature and also shows how to irrigate lateral canals.

  • Understand how to prepare canals using the Hyflex protocol using blocks as examples
  • Understand how to irrigate and obturate lateral canals using blocks as examples

Controlled memory navigation of curved canals. Part 9 - Dr. Antonis Chaniotis

Aims and objectives:

  • Questions and answer session with the live audience
