Article Abstract

Investigations carried out on maize roots under microgravity and hypergravity revealed that gravity conditions have strong effects on the network of plant electrical activity. Both the duration of action potentials (APs) and their propagation velocities were significantly affected by gravity. Similarly to what was reported for animals, increased gravity forces speed-up APs and enhance synchronized electrical events also in plants. The root apex transition zone emerges as the most active, as well as the most sensitive, root region in this respect.

CBCT Analysis of Incisor Movement and Alveolar Bone Changes in Class II Malocclusion Treatment with Premolar Extraction using Clear Aligner: A Retrospective Study.

J Dent

September 2025

State Key Laboratory of Oral Diseases & National Clinical Research Center for Oral Diseases; Department of Orthodontics, West China Hospital of Stomatology, Sichuan University, Chengdu, China.. Electronic address:

Objectives: This retrospective study evaluates alveolar bone remodeling patterns and their association with incisor displacement in adults undergoing clear aligner therapy with premolar extractions for Class II malocclusion correction.

Methods: Cone-beam computed tomography (CBCT) scans of 38 maxillary and 37 mandibular incisors were analyzed. Displacement vectors for four anatomical landmarks (cusp tip [C], root apex [R], root neck midpoint [M], labial cementoenamel junction [L]) were quantified.

Background: Advanced materials and techniques are used to successfully manage the apexification of immature teeth with open apices. The use of mineral trioxide aggregate (MTA), bioceramic sealers, and sodium hypochlorite (NaOCl), combined with internal heating and ultrasonic activation, ensures that canals are cleaned, disinfected, and sealed properly. Magnification devices, such as dental operating microscopes (DOM), provide precise visualization for accurate material placement, while the micro apical placement system ensures void-free MTA delivery.

Background: Pregnancy and parity induce physiologic adaptations in maternal calcium and bone metabolism, yet their specific effects on mandibular trabecular architecture remain insufficiently characterized. Evidence on craniofacial bone across parity is limited and conflicting, underscoring the need to clarify whether parity relates to mandibular bone quality.

Aims: The main aim of this study was to evaluate the effect of parity on mandibular bone architecture using fractal dimension analysis (FDA).

Is CBCT Helpful in Estimating the Risk for Oroantral Communication During Maxillary Posterior Tooth Extraction?

Department Head, State Key Laboratory of Oral & Maxillofacial Reconstruction and Regeneration, Key Laboratory of Oral Biomedicine Ministry of Education, Hubei Key Laboratory of Stomatology, School & Hospital of Stomatology, Wuhan University; Department Head, Department of Oral Surgery, School & Hosp

Background: Oroantral communication (OAC) is a perforation between the oral cavity and maxillary sinus, commonly occurring after maxillary posterior tooth extraction. The role of imaging in identifying high-risk cases remains unclear.

Purpose: The study aimed to estimate the association between periapical and cone beam computed tomography (CBCT) imaging with OAC exposure during maxillary posterior tooth extraction and evaluate the necessity of CBCT in clinical decision-making.

A reliable micro-CT-based method reveals dynamic changes to alveolar bone and tooth root following ligature-induced periodontal injury in the mouse.

This study presents a method development and evaluation framework for assessing longitudinally the dynamic alveolar bone changes in a murine periodontal injury model using 3D Slicer software. Accurate and reproducible measurement of bone loss is crucial for periodontal research, yet traditional two-dimensional (2D) histological approaches lack the ability to capture three-dimensional (3D) alterations, while inconsistencies in image alignment, region of interest (ROI) selection, and segmentation have limited the widespread adoption of 3D micro-CT analysis in small animal models. Here, we present a standardized workflow, incorporating defined criteria for ROI selection, scan alignment, and segmentation suitable for live micro-CT scanning.
