Dentin dysplasia (DD) is a rare autosomal dominant disorder of dentin development, which is generally divided into two types based on the clinical and radiographic appearance of the affected dentinal tissues: Type-I (Radicular DD) and Type-II (Coronal DD). This paper reports the case of a 17-year-old female patient with both classical and atypical features of radicular DD in the permanent dentition. The present case shows clinically normal appearing crowns, localised mobility in the maxillary teeth, completely obliterated pulp chambers, widened root canals without any obliterations and the presence of multiple periapical radiolucencies. The clinical and radiographic findings observed in this present case report are different from those reported in the past literature, which suggests that the present case could be a variation of radicular DD.

Evaluating the effectiveness of interlaminar epidural steroid injections for cervical radiculopathy using PROMIS as an outcome measure.
Interv Pain Med

University of Rochester Medical Center, 601 Elmwood Avenue, Rochester, NY, 14623, USA.
Background: Cervical interlaminar epidural steroid injections (CIESI) are frequently used to treat cervical radiculopathy due to cervical nerve root impingement.
Objective: The purpose of this study was to evaluate the therapeutic effect of CIESI for patients with cervical radiculopathy.
Methods: We conducted a retrospective review of consecutive adult patients with cervical radicular pain and corroborative cervical spondylotic foraminal stenosis on MRI that failed at least 6 weeks of conservative management consisting of medication and physical rehabilitation seen at a multidisciplinary, tertiary academic spine center.
Normal, accessory, and aberrant branches of the common iliac artery: angiographic prevalence and clinical implications.

Purpose: Catheter angiography remains essential to detect, characterize, and treat many vascular, traumatic, and neoplastic conditions affecting the pelvis, but the angiographic literature rarely mentions the common iliac artery (CIA) and its branches. The "normal" branches of the CIA principally consist of subangiographic rami supplying neighboring structures. Larger branches participate in the vascularization of the psoas muscle and the ureter.

Introduction: This study aimed to investigate radicular dentin thicknesses in mandibular second molars (MSMs), considering variations in root configuration and the morphology of the pulp chamber floor (PCF). The types of radicular grooves and potential danger zones were also identified.
Methods: A total of 149 MSMs were scanned with micro-computed tomographic imaging and classified into 4 groups according to root fusion and PCF morphology as follows: (1) 45 with fused roots and C-shaped PCFs, (2) 45 with fused roots and non-C-shaped PCFs, (3) 14 with a single canal, and (4) 45 with separated roots.
Prevalence, risk factors, natural history, and prognostic significance of Modic changes in the cervical spine: a comprehensive systematic review and meta-analysis of 12,754 participants.

Department of Neurosurgery, Brigham and Women's Hospital, Harvard Medical School, Boston, USA.
Objective: Modic changes (MCs) in the cervical spine are common, but remain an under-researched phenomenon, particularly regarding their prevalence, natural history, risk factors, and implications for surgical outcomes. This systematic review and meta-analysis endeavors to elucidate the multifactorial dimensions and clinical significance of cervical MCs.
Methods: Following PRISMA guidelines, a comprehensive systematic search was performed using Medline (via PubMed), EMBASE, Scopus, and Web of Science databases from their dates of inceptions to September 4, 2023.
Effect of different post materials and designs on upper central tooth torque and intrusion load: A finite element analysis study.
Int Orthod
December 2024
Department of Orthodontics, Afyonkarahisar Health Sciences University, Afyonkarahisar, Turkey.
Purposes: The aim of this study was to examine the effects of post material type and the presence of ferrules on the torque and intrusion load of the upper central tooth using finite element analysis.
Methods: The upper central tooth and surrounding tissues (cortical bone, cancellous bone, and periodontal ligament) were modelled in three dimensions using the Spaceclaim software. Five simulated models (SM) different modifications were made to this main model: metal cast post (SM1) and glass fiber post-core with zirconium crown and without a ferrule (SM2), metal cast (SM3) post and glass fiber post with a ferrule and zirconium crown (SM4) and only zirconium crown (SM5).
