Oral Fine Motor Control in Patients With Anterior Maxillary Single Implants, Freestanding Teeth and Teeth Connected in 3‐Unit Bridges: An Experimental In Vivo Study

Clinical Oral Implants Research, EarlyView.
ABSTRACT Objectives The oral fine motor control is compromised in patients with full‐arch, bimaxillary bridges compared to those with natural teeth. No previous studies have examined the differences between the prosthetic treatments small anterior bridges and single anterior implants (SI). The aim of the study was to evaluate oral fine motor control in

A Randomised Controlled Trial Comparing a One‐Piece Zirconia Tissue‐Level Implant and Two‐Piece Titanium Bone‐Level Implant for Maxillary Single Tooth Replacement—3 year Results

Clinical Oral Implants Research, EarlyView.
ABSTRACT Objectives This RCT evaluated and compared the clinical performance of zirconia and titanium dental implants placed in the maxillary premolar region. Outcomes were assessed 3 years after prosthetic loading and included marginal bone level (MBL) changes, clinical parameters, aesthetic outcomes, and patient related outcome measures (PROMs ...

Patch Test Reactions to Dental Materials: A Retrospective Single‐Centre Study

Contact Dermatitis, EarlyView.
In this retrospective single‐centre study of 439 adults referred for suspected delayed‐type hypersensitivity to dental materials, 50.1% had at least one positive patch test reaction, most often to metals. Nickel (23.0%) and palladium (16.6%) pre‐dominated, whilst methacrylate positivity was uncommon (6.2%) and not fully captured by HEMA alone.

Tunnelling Nanotube‐Mediated Lysosome Sharing Promotes Osteocyte Survival via Transcellular Autophagy

Cell Proliferation, EarlyView.
This study provides the first definitive identification of tunnelling nanotubes (TNTs) between cultured osteocytes and shows TNT‐mediated lysosome transfer from healthy to stressed cells, restoring autophagic flux and preventing apoptosis. This discovery of transcellular autophagy reveals a new survival mechanism in osteocytes, offering potential ...

Biomechanical Analysis of 3D Printed and Thermoformed EVA Custom‐Made Mouthguard: Experimental and Finite Element Analyses

Dental Traumatology, EarlyView.
ABSTRACT Background/Objective 3D printed materials have been evaluated for fabricating mouthguards; however, little is known about their biomechanical performance in preventing dental trauma. This study aimed to compare two 3D printed polymers and three ethylene vinyl acetate (EVA) sheets used for mouthguard fabrication regarding their mechanical ...

Adhesion of Newly Developed Composite Resin Splinting Materials to Enamel: Effect of Enamel Surface Treatment

Dental Traumatology, EarlyView.
ABSTRACT Background/Aim To evaluate the shear bond strength (SBS) of newly developed composite resin materials intended for dental splinting to enamel and to determine whether phosphoric acid etching alone provides reliable adhesion. Material and Methods Four experimental materials (G‐Fix, Light Fix, Ortho Connect, and Ortho Connect Flow) were compared

Dens Invaginatus as a Biomechanical Risk Modifier in Dental Trauma: Finite Element Analysis

Dental Traumatology, EarlyView.
ABSTRACT Introduction/Aims Traumatic dental injuries are common in childhood and may adversely affect functional and psychosocial well‐being. Dens invaginatus, a developmental anomaly caused by the infolding of the enamel organ during odontogenesis, alters tooth morphology and may influence biomechanical behavior under traumatic loading.

Prevalence and Patterns of Multiple Injuries Affecting a Single Permanent Tooth (Combination Injuries): A Systematic Review and Meta‐Analysis

Dental Traumatology, EarlyView.
ABSTRACT Background Combination injuries or multiple traumatic dental injuries (TDI) affecting a single permanent tooth are clinically significant but remain underrecognized. Although the global prevalence of TDI is well documented, the epidemiology of combination injuries has not been clearly established. This systematic review and meta‐analysis aimed
