Article Synopsis
- The study aimed to evaluate and compare the effectiveness of Biodentine and Portland cement in repairing mid-root perforations in single-rooted mandibular premolars by analyzing stress distribution and fracture resistance.
- Using finite element analysis (FEA) and a physical testing approach, researchers created 3D models of various tooth conditions to assess how each repair method performed under stress.
- Results showed that Biodentine and Portland cement had similar stress distributions and that the highest stress was observed in the endodontically treated teeth, indicating that both materials were effective in ensuring structural integrity after repair.
Brachyolmia is a heterogeneous group of developmental disorders characterized by a short trunk, short stature, scoliosis, and generalized platyspondyly without significant deformities in the long bones. DASS (Dental Abnormalities and Short Stature), caused by alterations in the gene, was previously considered as a subtype of brachyolmia. The present study investigated three unrelated consanguineous families (A, B, C) with Brachyolmia and DASS from Egypt and Pakistan.

Methods: Twenty single-rooted mandibular premolars were endodontically prepared and divided into the following two groups according to the irrigation protocol used (n = 10): Group I: NaOCl + EDTA and Group II: continuous chelation (NaOCl/Dual Rinse). Obturation was performed with the warm vertical compaction technique using TotalFill HiFlow bioceramic sealer mixed with a fluorophore dye.
Objective: To evaluate the degree of postoperative pain and rate of analgesic intake in patients with symptomatic irreversible pulpitis in mandibular first molar teeth at 6 h, 12 h, 24 h, 48 h, and 72 h after using different irrigation activation techniques in single-visit endodontic treatment.
Methods: A total of 78 patients with symptomatic irreversible pulpitis with no signs of periapical pathology were randomly divided into 3 groups according to the final irrigation activation technique; Group XP-endo Finisher, Group Ultra X ultrasonic device, and Group side-vented needle. The teeth underwent standardised single-visit root canal treatment procedures using 2.
Objective: This study compared the quantity of extruded debris after instrumentation with TRUShape 3D Conforming files, TruNatomy files, and the WaveOne Gold reciprocating system.
Materials And Methods: Fifty-one mesiobuccal canals with severe curvatures (25-40°) were assigned to three equal groups according to the rotary system used for preparation, either TRUShape, TruNatomy, or WaveOne Gold files. The extruded debris was collected in pre-weighed glass vials.
