The Role of Bone and Root Resorption on the Biomechanical Behavior of Mandibular Anterior Teeth Subjected to Orthodontic Forces: A Finite Element Approach

Biomedicines
Aims: This study was conducted to systematically evaluate the biomechanical impact of varying degrees of root and bone resorption resulting from periodontitis and orthodontic tooth movement (OTM) on the mandibular anterior teeth.

Digital Microneedles for Multiplexed Transdermal Sensing via Fluorescent QR Codes

Advanced Materials, EarlyView.
Digital fluorescent microneedles encode biochemical information in skin into scannable QR codes through threshold‐activated probes that generate binary on/off signals. By transforming analog fluorescence into discrete digital patterns, this platform enables calibration‐free, multiplexed transdermal sensing of physiologically relevant biomarkers ...

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.

Elephant‐Skin‐Inspired Porous Cementitious Tiles with Programmable Crack Networks for Passive Cooling

Advanced Materials, EarlyView.
Elephant‐skin‐inspired crack networks are programmed in porous diatomaceous earth (DE)‐cement composites using substrate‐guided, stress‐concentration induced fracture. The resulting crack lattices act as capillary conduits that redistribute water, while the porous matrix stores moisture.

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 ...

Atomic Layer Deposition of Metallic Molybdenum Dioxide Thin Films Enabling High‐k Rutile Capacitors

Advanced Materials Interfaces, EarlyView.
The first direct atomic layer deposition (ALD) process of molybdenum dioxide (MoO2) thin films is reported using molybdenum(II) acetate dimer (Mo2(OAc)4) and oxygen (O2) as precursors at 235°C–275°C. The films are crystalline, exceptionally pure, and conductive.

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,
