Anatomical Analysis Of Inferior Alveolar Nerve Relation To Mandibular Posterior Teeth Using Cone Beam Computed Tomography: A Retrospective Radiographic Analysis Study, Shehabeldin Mohamed Saber Prof.Dr.

Dentistry

Introduction: Cone beam computed tomography (CBCT) is reliable in the assessment of structures related to teeth. The assessment of the inferior alveolar neurovascular (IAN) bundle location using CBCT is considered one of its prime uses in different mandibular surgeries. Methodology: Retrospective CBCT data of patients presented to the institute were assessed to measure relations of IAN. Measurements were taken to assess the bone thickness adjacent to IAN, the superior-inferior dimension between the canal and the teeth, and the dimension between the canal and the inferior border of the mandible. Results: Out of the 170 patients the root apices nearest to …

Aesthetic Rehabilitation Of A Complex Crown-Root Fracture By Fragment Reattachment With A Fiber-Reinforced Post: A Case Report, Sarra Saidi, Meriem Fejjeri, Mahdi Tlili, Sabra Jaafoura, Nadia Frih

International Arab Journal of Dentistry

Complex crown-root fractures are characterized by the involvement of both crown and root with pulp exposure. They pose aesthetic, functional, and psychological problems for the patient. Furthermore, they can pose technical difficulties for the practitioner. The purpose of this case report is to describe the management of a complex crown-root fracture of the right upper central incisor with subgingival limit by reattaching the tooth fragment with fiber-reinforced post. We considered a coronal elongation (gingivectomy and osteoplasty) to recreate the biological space and to expose the limit of the fracture line to guarantee the quality of the bond.

Diagnosis And Endodontic Treatment Of Odontogenic Cutaneous Sinus Tracts: A Report Of Two Cases, Mayada Jemâa, Marwenne Bouatay, Yesmine Neifar, Mohamed Bassem Khattech

International Arab Journal of Dentistry

Introduction: The odontogenic cutaneous sinus tract (OCST), caused by pulp necrosis, creates connections between pathological spaces and anatomical structures. Extraoral manifestations pose diagnostic challenges leading to inappropriate treatments such as multiple surgery and antibiotic therapies. Effective management requires the treatment of dental pathology through endodontic therapy or extraction. This paper presents two cases of OCST and emphasizes the importance of accurate diagnosis and successful non-surgical endodontic treatment.

Observations: Case report 1: A 23-year-old male patient referred by his dermatologist with a cutaneous sinus tract on his chin that had appeared five years ago. During this period, he reported …

International Arab Journal of Dentistry

Objectives: This 7-years follow-up case report describes two diversified strategies for the management of bilateral mandibular permanent premolars associated with periapical lesion and unerupted supernumerary teeth.

Case Report: A non-syndromic 9 years-old Asian female patient presented pain and swelling of the 35 in anatomical contiguity with an immature and unerupted supernumerary tooth. Clinical examination revealed an intraoral vestibular sinus tract related to the necrotic 35. Periapical radiography and CBCT showed that the 35 had an immature apex associated with a periapical lesion, and a supernumerary tooth in a lingual direction. Endodontic treatment of the 35 was performed by creating …

International Arab Journal of Dentistry

Objectives: The aim of this in-vitro study is to assess and compare the load capacity of teeth with canals prepared using progressive taper versus regressive taper.

Methods: Twenty-seven extracted mandibular molars were categorized into three equal groups. The negative control group involved teeth that were accessed and restored with composite resin without canal preparation. The regressive canal preparation group used the TruNatomy file system, while the progressive canal preparation group employed the ProTaper Gold system. Subsequently, all samples underwent loading using a universal testing machine until tooth fracture occurred. The force required to fracture each tooth was recorded …

Dentin-Sealer Bond Strength. A Review: An In-Vitro Comparison Between Guttaflow 2 ®, Endosequence Bc High Flow ®, Tubli-Seal ®, Sealapex ®, And Ah Plus Jet ® Sealers., Zied Diab

Graduate Theses, Dissertations, and Problem Reports (ETD)

Introduction: One objective of non-surgical endodontic therapy is the formation of a hermetic seal with elimination of any portal of entry of bacteria and their byproducts into the root canal space from periapical tissue. Extensive research has been conducted to determine ideal endodontic sealers. Bioceramic sealers have risen to prominence due to reported decreased shrinkage, less toxicity, and superior bond strength to root dentin compared to zinc oxide eugenol, calcium hydroxide, and resin-based sealers. GuttaFlow2®, a new sealer on the market, is composed of calcium silicate in combination with gutta-percha particles. Researchers from Coltene (Altstätten, Switzerland), the manufacturer of GuttaFlow2® …
