When the surgical endodontic treatment fails, the failure may be attributed to incorrect diagnosis and the surgical technique used or materials employed. Endodontic microsurgery has evolved tremendously in the last decade and is fundamentally different from traditional apical surgery. There are now many clinical studies supporting the predictable and positive outcome of modern endodontic microsurgery and re-surgery in the management of post-treatment endodontic disease. Endodontic re-surgery can now be considered a good alternative for failed surgically treated teeth with post-treatment endodontic disease.
To understand the etiology of postsurgical treatment endodontic disease.
To appreciate the difference between traditional apical surgery and modern endodontic microsurgery.

"Cracked Teeth (CT)" is among the top three leading causes of tooth loss. CT has been well defined and acknowledged since the 1960s but to this day, its management has not received much attention it deserves. In order to understand CT before it further causes coronal and root fractures, it is important for a clinician to recognize and detect cracks while it is in its initiation stage and how it could progress to reversible or irreversible pulpitis.
This lecture aims to:
1.Be able to understand how tooth structure cracks complicate and affect dental treatment.
2.Learn the different classifications, etiology and initiation mechanism of cracks.
3.Know how endodontic treatment can be of help or also be a factor in causing cracks.
4.Know the role of the restorative design in preventing cracks following tooth restoration.

Dental pulp tissue is encapsulated with dentin, a specialized hard tissue, and blood supply to the pulp mainly comes from the apex. Therefore, the pulp tissue of avulsed/luxated teeth, which frequently develops abundant mineralization, easily suffers from hypoxia by disruption of the blood supply. Following the progress of pulp inflammation, circulatory impairment and resulting ischemia can readily occur following inflammatory exudation, which increases the tissue pressure leading to vascular compression. However, the involvement of hypoxia in mineralization and inflammation in the pulp tissue is still unclear. Recently, we have revealed that hypoxia and hypoxia inducible factor 1α (HIF1α), a typical transcriptional factor of hypoxia, promote osteo/odontoblastic differentiation of human dental pulp stem cells via B-cell CLL/lymphoma 9 (BCL9), which is a Wnt/β-catenin transcriptional cofactor. Furthermore, HIF1α negatively regulates interleukin-6 synthesis in lipopolysaccharide-stimulated human dental pulp cells via upregulation of suppressor of cytokine signaling 3 and subsequent downregulation of CCAAT element binding protein beta. This lecture will focus on the mineralization-inducing and anti-inflammatory effects of hypoxia/HIF1α as a new insight into the biology of the pulp tissue.

The decision as to whether to incorporate an endodontically treated tooth in a periodontal/restorative treatment plan is often difficult. The availability of other successful treatment alternatives (dental implants) further complicates the issue. Yet, the retention of the natural dentition has many benefits for the patient. Endodontic success rates are high given new technologies and treatment modalities but is undeniably tied to restorative and periodontal factors. This lecture will focus on the evidence that endodontic therapy (initial therapy, retreatment, and surgical procedures) is still a viable and successful alternative in saving teeth which can be strategically used in restorative treatment plan. The prognosis for endodontically treated teeth will be considered along with an approach to determine the appropriate endodontic modalities when considering retaining natural teeth.

Saving infectious natural teeth with an endodontic treatment hasn’t always been an easy task. Sometimes there are lot of endodontic challenges to preserve what is remaining. Whatever be the challenge if done with correct endodontic approach and a zeal in mind to conserve the nature, it can be rewarding to both patient and dentist. Basically, endodontic challenges can be overcome by two different approaches either Orthograde or Retrograde with appropriate choice of biocompatible materials.

Introduction : The field of medicine and dentistry are beginning to integrate Artificial Intelligence (AI), especially deep Learning (DL) in diagnostics, thereby eliminating subjectivity and improving accuracy of diagnoses and treatment planning. Current evidence on pathology detection on Orthopantomograms (OPGs) either indicate the presence or absence of disease in the entire image; literature on the relation of pathology to causative tooth is lacking.
Objective : To develop a DL AI model for the segmentation of periapical pathology and its relation to teeth on OPGs.
Methodology : 250 OPGs were manually annotated by subject experts to establish ground-truth for training an AI model on segmentation of periapical pathology. The labelling of periapical pathology was carried out denoting two classes; class 1: uncertain periapical lesion; and class 2: certain periapical lesion. An untrained U-net algorithm was trained and validated on the labelled dataset. Our existing trained model on teeth segmentation and numbering tasks was also further trained on 250 labelled OPGs to improve performance and accuracy. Both models were then integrated which allowed for relation of periapical pathology to the causative tooth on OPG.
Results : The performance of the existing teeth segmentation and numbering model was further improved as indicated by the following performance metrics including accuracy=98.1%, precision=91.8%, re-call=93.3%, F-1 score=92.5%, dice index=90.1% and Intersection over Union (IoU)=82.1%. The performance metrics of lesion segmentation carried out by the current model are as follows: accuracy=98.1%, precision=84.5%, re-call=80.3%, F-1 score=82.2%, dice index=75.2% and IoU=67.6%.
Conclusion : Our integrated AI model performs the task of lesion detection and its relation to the causative tooth on OPG with comparable results to that laid down in the ground truth as indicated by performance metrics.

To the lay person, when the words AI or Artificial intelligence are used, it conjures up images of violent state of the art robots taking over the world and eliminating the human race. Using AI to speed up and improve upon the limitations of humans is not new, since the early 1950’s research on AI has been proceeding steadily. AI has infiltrated all aspects of our life such as search engines, facial and speech recognition software. AI in dentistry is a growing field of research and its application in endodontics is growing. This lecture outlines the current status of AI in Endodontics, its current application and its future directions.

The goal of root canal preparation is to remove vital and necrotic pulp remnants, microorganisms, and microbial toxins, through mechanical preparation of the root canal space and chemical disinfection. To achieve this objective the curved root canals is difficult with the use of stainless-steel files. They are stiff and tend to make so many aberrations. Over two decades, nickel-titanium (NiTi) instrument plays an important role in root canal preparation; improved preparation quality and greatly reduced aberrations. In clinical use, nickel-titanium rotary instrument shows different performance depending on the design and mechanical properties. A variety of models and methods have been used to investigate the mechanical properties and behavior of NiTi instruments. The aim of the lecture is to review the testing methods of nickel-titanium rotary instruments and to present the related study results.

It is an established fact now that apical periodontitis is a disease induced by biofilms. Cleaning and shaping of the root canals using instrumentation, irrigation, and intracanal medicaments play an essential role in eliminating bacteria and bacterial biofilms. The role of intracanal medicaments is strategically important in eliminating these bacteria after the chemo-mechanical preparation.
This presentation will review the currently used intracanal medicaments and if there is a need to modify the current strategies according to various host and medical factors and future directions.

Lesion sterilization and tissue repair (LSTR) therapy includes applies of a triple antibiotic mixture in a suitable vehicle, which is considered to disinfect, regenerate and revascularize the dental infection. In endodontics, LSTR has been vastly applied and varied from vital pulp therapy to the recently introduced regeneration and revascularization protocol. Five patients with different clinical manifestations were treated with the aim to preserve the tooth pulp vitality, disinfect the root canal system and promote regeneration capacity of pulp tissue by undifferentiated mesenchymal/stem cells. These reports highlighted five cases with exposed pulp, pulp polyp, tooth with sinus/fistula etc. where LSTR therapy was applied with triple antibiotic paste. Cariology Research group of Niigata University Graduate School of Medical & Dental Science, Niigata, Japan and Conservative Dentistry & Endodontics department of Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh jointly conducted this study.
Case-I:exposed pulp was treated with vital pulp therapies such as direct pulp capping using LSTR therapy. Case-II: carious destruction with pulp polyp was treated with pulpectomy procedure with a triple antibiotic mixture or LSTR therapy. Case –III: hopelessly carious tooth was also treated by pulpectomy procedure with a triple antibiotic mixture. Case-IV: destructed deciduous tooth with buccal swelling as well as sinus was treated with a triple antibiotic mixture. Case-V: a failed root canal treatment with fracture reamer in apical region was also treated by LSTR therapy. All tooth samples mentioned above were rehabilitated by permanent restoration and inlay. Clinical and radiographic examinations were performed at 3, 6, 12 and 24 months. At the end of 24 months, the patients were completely asymptomatic and free of any clinical and radiographic signs of inflammation and periapical lesion. Follow-up examinations revealed reduction of periradicular pathosis in all the five cases.
This case reports open a perspective on the use of LSTR therapy in endodontics as an alternative option to foregoing the more invasive root canal therapy and extraction in treating pulpally involve tooth with gross periradicular pathosis. LSTR therapy is very much effective, less time-consuming treatment. We can use this therapy confidently but proper technique must be maintained with proper knowledge.

The Ins and Outs of Cracked Teeth
Lecture hall :
Bachelor of Dental Surgery (BDS)
Master of Dental Surgery (Endodontics) (MDS)
Registrar, Restorative Dentistry, National Dental Centre Singapore
Cracked teeth are defined by having a thin surface disruption of enamel and dentin,and possibly cementum, of unknown depth or extension. Cracked teeth are becoming increasingly prevalent in developed countries. Patients are now more dentally aware after decades of public dental education. This, coupled with heavy masticatory function, results in teeth being kept for longer periods and being succumbed to repeated loading. As a result, there is a predisposition for the development of cracked teeth in these patients. The etiology and predisposing factors of these teeth will be discussed. Evidence on the prevention, diagnosis and management of cracked teeth is heterogeneous. Although evidence suggests that cuspal protection and early detection is paramount in the management of cracked teeth, there is currently no one specific method that is favored over the other. Vital cracked teeth have been suggested to be treated using crowns or other indirect restorations definitively. However, it has also been suggested that these teeth require an interim period of stabilization prior to definitive restorations to avoid further trauma to an inflamed pulp during crown preparations. The existing literature will be discussed. Non-vital cracked teeth require root canal treatment prior to crowns. However, understanding the factors leading to treatment failure will also help us to better advise patients on the prognosis and appropriate treatment for these teeth. Management strategies for vital and non-vital cracked teeth differ.
In this lecture, we discuss the evidence behind the different management strategies for cracked teeth. Several new technological advancements in the detection of cracked teeth will also be discussed.

Member of the editorial board of the International Endodontic Journal and also acts as a scientific reviewer for a series of endodontics/dental journals
Research interests mainly focus on Electronic Root Canal Length Measurement Devices, Calcium Silicates, Post-operative Pain in Endodontics, Treatment of Immature Root Canals, Automated Root Canal Preparation, Physiopathology of Periapical Lesions and Regenerative Endodontics
Regenerative endodontics is a novel approach to restore the vitality and function of the pulp-dentin complex in teeth with pulp necrosis and immature root development. Conventional root canal therapy, which involves cleaning and filling the root canal space with inert materials, may compromise the long-term prognosis of these teeth due to the thin dentinal walls and open apices. Regenerative endodontics, on the other hand, uses the principles of tissue engineering to promote the regeneration of pulp-like tissue within the root canal system, allowing for continued root maturation and increased dentinal thickness. This lecture will provide an overview of the biological basis, clinical protocols, and outcomes of regenerative endodontic procedures, as well as discuss the challenges and future directions of this emerging field. The lecture will also compare and contrast regenerative endodontics with conventional root canal therapy and other alternative treatments for immature teeth with pulp necrosis. The aim of this lecture is to introduce the audience to the paradigm shift that regenerative endodontics represents in endodontic treatment and to highlight its potential benefits for oral health and quality of life.
