CLINICAL ATLAS OF RETREATMENT IN ENDODONTICS

Explore a comprehensive pictorial guide to the retreatment of root canals and failed endodontic cases with step-by-step advice on retreatment management

Clinical Atlas of Retreatment in Endodontics delivers an image-based reference to the management of failed root canal cases. It provides evidence-based strategies and detailed clinical explanations to manage and retreat previous endodontically failed cases. It contains concrete evidence-based and practical techniques accompanied by full-colour, self-explanatory clinical photographs taking the reader through a journey of successful management of the failed clinical cases.

Using a variety of clinical cases, the book demonstrates why and how endodontic failures occur, how to prevent them, and how to manage them in clinical practice. It also emphasises on evaluating the restorability and prognosis of the tooth in order to make a proper case selection for providing retreatment. This book also discusses the various factors that can help the clinician to make a case for nonsurgical or surgical retreatment. Readers will benefit from the inclusion of clinical cases thatprovide:

• A thorough introduction to perforation repair, with a clinical case that includes the repair of pulpal floor perforation caused due to excessive cutting of the floor of the pulp chamber
• An explanation of various factors for instrument separation, supported with a case that includes the removal of a fractured instrument
• Practical discussions of instrument retrieval, with a case that includes a fractured instrument at the apical third of mandibular molar
• A step wise pictorial description for guided root canal therapy
• Selective root canal treatment as a treatment option for retreatment of failed endodontic cases
• A detailed clinical description for how to explore and modify the endodontic access cavity for locating extra/missed canals

Perfect for endodontists, endodontic residents, and general dentists, Clinical Atlas of Retreatment in Endodontics is also useful for undergraduate dental students and private practitioners who wishto improve their understanding of endodontic retreatment and are looking for a one-stop reference on the subject.

Clinical Case 1 – Perforation repair: A case of repair of pulpal floor perforation caused by excessive cutting of the floor of the pulp chamber

Mohammad Hammo

Introduction to the case: pulpal floor perforation caused by excessive cutting of the floor of the pulp chamber.

1.1 Patient information

• Age: 30 years old.
• Gender: female.
• Medical history: non‐contributory.

1.2 Tooth

• Identification: mandibular left first molar (Tooth 36).
• Dental history: discomfort due to impingement of food inside her molar. Previous treatment done on this tooth 1 year ago.
• Clinical examination findings: deep decay, tooth was filled with food remnants, no mobility, no pain to percussion. After cleaning the tooth, big perforation was noted and bleeding also.
• Preoperative radiological assessment: deep decay and lesion at furcation area due to perforation (Figure 1.1).
• Diagnosis (pulpal and periapical): previously initiated root canal therapy with asymptomatic apical periodontitis.

1.3 Treatment plan

• First visit: local anaesthesia, rubber dam isolation, magnification (dental operative microscope), conventional access cavity, identification of orifices of the canals, placing cotton pellets inside them, stopping the bleeding physically with cotton pellet (Figure 1.2).
• Treatment plan for management of the endodontic mishap: applying MTA at the furcation area, then inserting a wet cotton pellet over MTA, temporary filling (Figure 1.3).

  

  Figure 1.1 Preoperative radiograph showing radiolucency in the furcation area.

  

  Figure 1.2 Clinical picture showing the pulpal floor perforation.

  

  Figure 1.3 Radiograph showing MTA placed on the pulpal floor.

• Second visit: removing temporary filling and cotton pellets, Check the condition of MTA (hardness), canal preparation with rotary files.
• Irrigation protocol (solution and technique): 5.25% NaOCl; passive sonic irrigation.
• Final irrigation protocol: 17% EDTA (syringe irrigation) for 1 minute.
• Obturation (materials and technique): zinc oxide‐based sealer (Sealite^TM Ultra) and gutta‐percha; warm vertical compaction.
• Permanent filling (Figures 1.4 and 1.5).
