Apical Root Resorption after Orthodontic Treatment

Česká Stomatologie a Praktické Zubní Lékařství, 2012
Aim: The aim of the present study was to assess the incidence of apical root resorption in patients treated with fixed orthodontic appliances and find out whether the frequency of their occurrence depends on sex, patient's age, Angle class malocclusion ...

Combination of 3D and 2D Small and Wide Angle X‐Ray Scattering Imaging Reveals Diminished Bone Quality in the Superior Human Femoral Neck Cortex

Advanced Materials, EarlyView.
Combined 2D and 3D X‐ray scattering imaging is used to analyse nanostructural properties in the inferior and superior cortex of 78 human femoral necks from 44 donors. The methodology allows for increased interpretation of nanostructure in a statistically relevant dataset, revealing nanostructural differences in anatomical locations critical to clinical

Deterministic Nucleation of Nanocrystal Superlattices on 2D Perovskites for Light‐Funneling Heterostructures

Advanced Materials, EarlyView.
This work investigates the heterogeneous nucleation of CsPbBr3${\rm CsPbBr}_3$ nanocrystal superlattices along the faces of 2D PEA2PbBr4${\rm PEA}_2{\rm PbBr}_4$ layered perovskite microcrystals. Core–crown and core–shell heterostructure morphologies are obtained.

Maskless Fabrication of PLA‐Based Neural Arrays for CNS Recording and Stimulation

Advanced Materials Interfaces, EarlyView.
Biodegradable neural interfaces enable bidirectional communication with the CNS. Through electrochemical characterization, ageing tests with impedance monitoring, and in vivo validation, we assess the performance of PLA‐based epicortical and spinal implants.

Root Resorption Patterns of Primary Mandibular Molars and Location of Premolar Successors Through Radiographs in Pakistani Population

Pakistan Journal of Medicine and Dentistry
Background: Primary teeth undergo physiological root resorption followed by eruption of their permanent successors. Roots of primary mandibular molars can have either symmetrical or asymmetrical resorption patterns.

An Imaging‐Guided, Patient‐Specific Guiding Aid (RWNGuide) for Safe and Reproducible Inner Ear Drug Delivery

Advanced Materials Technologies, EarlyView.
A patient‐specific, imaging‐guided aid enables precise and reproducible drug delivery to the inner ear. By guiding therapeutic agents directly to the round window niche, this approach reduces variability in drug localization, improves delivery safety, and addresses a critical bottleneck in inner ear therapy, offering a scalable strategy for precision ...

Effects of fixed orthodontic lingual retainers on PDL stress, root resorption risk, and tooth displacement

Scientific Reports
To date, no study has compared the effects of CAD/CAM versus flexible multistrand wire (FMS) retainers in the presence/absence of root resorption and/or alveolar crestal bone resorption on the anterior mandibular teeth’s stresses/displacements. Therefore,

Orthodontic treatment in patient with idiopathic root resorption: A case report

Dental Press Journal of Orthodontics, 2015
Multiple idiopathic external root resorption is a rare pathological condition usually detected as an incidental radiographic finding. External root resorption of permanent teeth is a multifactorial process related to several local and systemic factors ...

Temperature Correction in a Single Luminophore Pressure‐Sensitive Paint Using a Dual‐Emitting Gold Acridine Complex

Advanced Optical Materials, EarlyView.
The use of pressure‐sensitive luminescent molecules to quantify surface pressure in wind tunnel testing has revolutionized experimental aerodynamics. This work develops a dual‐emitting gold acridine complex for the simultaneous sensing of pressure and temperature independently of each other.

Digital Twin of a One‐Sun‐Driven Luminescent‐Concentrator‐Assisted Planar Solar‐Pumped Fiber Laser

Advanced Optical Materials, EarlyView.
An experimentally‐validated digital twin of a one‐sun solar‐pumped fiber laser enables a design exhibit 13‐times higher output power at 1064 nm to be achieved. Despite its simple appearance, the multitude of choices in the design parameters make finding this improved very tedious in the lab, thus the digital twin can save significant time and effort ...
