Practice limited to micro-endodontics
Dr. Ahmed is a Micro-Endodontic consultant. He lectures extensively nationally as well as internationally. The academic field of research of Dr. Ahmed Shawky is “Regenerative Endodontics” in which he published and is currently publishing laboratory and clinical studies. He is currently an OPL in DENTSPLY-Sirona MENA. He conducted more than 25 CE certified endodontic trainings both nationally and internationally.
The primary objective of nonsurgical endodontic treatment is the healing of existing, as well as prevention of recurrence of, apical periodontitis. This objective can be fulfilled by disinfection of persistent residual microbes present in the root canal system. Shaping is an important step to fulfill the disinfection allowing delivery of the irrigating solutions as close […]
Following the access preparation and location of anatomy, the next challenge facing the endodontic clinician is to select the proper alloy and sequence for the shaping procedures in order to be able to safely and predictably shape the anatomy without any procedural errors. This article will show the advantages of the MG3 Gold instruments and […]
The Primary objective of endodontic treatments is treatment and/or prevention of apical periodontitis. To achieve this goal, the endodontist must be able to process all the case givens to reach a conservative and predictable treatment. This articles describes the decision making process in non-surgical retreatments of two mandibular molars throughout the endodontic workflow.
Following the access preparation and location of anatomy, the next challenge facing the endodontic clinician is to select the proper alloy and sequence for the shaping procedures in order to be able to safely and predictably shape the anatomy without any procedural errors. This article will show the advantages of the MG3 Blue instruments and […]
The most common reason for fracture of rotary NiTi files are flexural and/or torsional fatigue. Even single use of instrument, can reduce the fracture incidence by only 0.9%. Unfortunately, even with advancements in metallurgy, file breakage could not be entirely overcomed due to the fact that the more the flexible the instruments, the more they […]
Various regenerative endodontic treatment (RET) protocols have been suggested with differences mainly in the disinfection technique used, intracanal medicaments, scaffold systems, and coronal filling materials. In order to reduce such variability, the American Association of Endodontists (2013) and European Society of Endodontology (2016) developed evidence based recommended protocols. These guidelines helped reduce some of the […]
The main goal of endodontic treatment is the treatment and/or prevention of peri-radicular periodontitis aiming for a long term disease-free survival. The presence of any form of communication between the pulp space and the periodontist and/or the oral cavity will lead eventually to development or recurrence of peri-radicular disease which will prevent the clinician from […]
Access cavity preparation is considered as the most important step in the endodontic treatment protocol. Inability of the operator to visualize anatomical requirements of the preparation may end in aggressive mishaps which complicate the treatment procedures or compromise the ultimate treatment outcomes. Being the most important step in endodontic treatment course, access cavity preparations must […]
Proper clinical practice in Endodontics requires careful and detailed knowledge on the know how of using different instruments, tools and devices used in the treatment course. Even in the simplest cases, violating the limitation of some instruments or misusing/misplacing those instruments may lead to severe iatrogenic errors which may act as a barrier against providing […]
For invasive cervical resorption to occur and propagate, there must be a damage in the periodontal ligament and cementum in addition to a contributing factor(s) which is assumed to sustain the osteoclastic activity. Although the etiology of ICR is poorly understood in literature and there might be some etiological factors which have not yet been […]
Vital pulp therapy (VPT) are those procedures carried out to maintain the dental pulp in a healthy condition, allowing to preserve its defensive function and sustaining its ability to form dentin in response to irritation. Despite the favorable outcomes of VPT, some complications might occur as a result of improper case selection or technical factors. […]
Invasive cervical resorption is characterized circumferential spread with/without coronal-apical spread in dentin where the involvement of the pulp may be delayed being present in advanced cases due to the presence of peri-canal resorption resistant sheet (PRRS) composed primarily of pre-dentin and odontoblasts Invasive Cervical Resorptive lesions have different radiographic presentations, ranging from a small radiolucency […]
Root perforations are defined as communications between the root canal space and the periodontium. These communications may be caused by a pathological process (as: external or internal resorption) or as a result of an iatrogenic error (as: misdirection/improper size of the post space drill, drilling through the chamber floor or improper root canal instrumentation)1.
