Background: The aim of this study was to evaluate obturation depth and volume by means of micro-CT when filling lateral canals.
Material And Methods: Thirty single-rooted teeth were used. After instrumentation, three artificial lateral canals were created on each mesial and distal surface (one on each third). The samples were then separated randomly into three groups according to the obturation technique used (n=10): lateral condensation (Group 1), Tagger's hybrid technique (Group 2) and GuttaCore™ (Group 3). Samples were scanned and data was processed with Avizo software. Depth and volume of the infilling were measured in each lateral canal. Values were expressed as percentages and were analyzed using the Kruskal-Wallis test.
Results: Mean depth showed statistically significant differences between Group 3 and Groups 1 (=0.001) and 2 (=0.003), whereas no significant difference was found between Groups 1 and 2 (≈1). As for mean volume, significant differences were found between Group 3 and Groups 1 (=0.01) and 2 (=0.003) but no differences were found between Groups 1 and 2 (=1.00).
Conclusions: GuttaCore provided the best lateral canal sealing among the three techniques compared. Lateral canals, Micro-CT, obturation.

Purpose: Cochlear implantation (CI) surgery is essential for restoring hearing in individuals with severe sensorineural hearing loss. Accurate placement of the electrode within the cochlea is essential for successful auditory outcomes and minimizing complications. This study aims to analyze the relationship between the round window niche (RWN) alignment, its visibility during surgery, and the impact on surgical techniques and outcomes.

Autosomal recessive hypophosphatemic rickets type 2 (ARHR2) is an uncommon hereditary form of rickets characterised by chronic renal phosphate loss and impaired bone mineralisation. This results from compound heterozygous or homozygous pathogenic variants in ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1), a key producer of extracellular inorganic pyrophosphate (PPi) and an inhibitor of fibroblast growth factor23 (FGF23). ENPP1 deficiency impacts FGF23 and increases its activity.

Purpose: To investigate the relationship between spinal cord anatomy and the risk of curve progression in mild to moderate adolescent idiopathic scoliosis (AIS).
Methods: We prospectively included patients presenting with mild or moderate AIS (< 40 degrees). Irrespective of curve severity, patients underwent 3-dimensional MRI and were followed until skeletal maturity or surgery.

Background: Endodontic file fractures are common complications of root canal treatment, and requires removal via specialized techniques such as endodontic microsurgery when the file beyond the apical foramen. It is often challenging to precisely and minimally remove a fractured file. Recently the use of dental autonomous robotic system (ATR) has shown promise in precisely and minimally in dental surgery.

Objective: To examine the anatomical and morphological structure and potential pathological conditions of the submandibular gland by performing Cone Beam Computed Tomography (CBCT) sialography in patients with diabetes mellitus.
Study Design: The submandibular salivary glands of 25 diabetic and 25 healthy volunteers were examined by CBCT sialography. The images were evaluated to determine the main and lateral canals, the diameter of the main canal, the presence of ductal stenosis, central ductal dilatation, acinar pooling, the presence of sialoliths, and the visualization of the main and lateral canals and parenchyma.
