Exploring the association between orthodontic treatment and temporomandibular disorders in pediatric patient: A retrospective study.

Objective: This retrospective study aimed to investigate the association between orthodontic treatment and development of temporomandibular disorders (TMDs) in pediatric patients.

Methods: This study analyzed 122 pediatric patients (age 10-18 years) who underwent orthodontic treatment. The inclusion criteria included comprehensive orthodontic records and substantial clinical documentation, while the exclusion criteria targeted preexisting TMDs or syndromes affecting the temporomandibular joint.

Oral cancer stem cells: A comprehensive review of key drivers of treatment resistance and tumor recurrence.

Oral squamous cell carcinoma (OSCC) remains a major cause of morbidity and mortality worldwide with high recurrence rates and resistance to conventional therapies. Recent studies have highlighted the pivotal role of oral cancer stem cells (OCSCs) in driving treatment resistance and tumor recurrence. OCSCs possess unique properties, including self-renewal, differentiation potential, and resistance to chemotherapy and radiotherapy, which contribute to their ability to survive treatment and initiate tumor relapse.

Factorial analysis of variables affecting bone stress adjacent to mini-implants used for molar distalization by direct anchorage-A finite element study.

Objective: The aim of this study was to investigate the stresses on mini-implant, cortical bone, and cancellous bone for maxillary molar distalization using an orthodontic implant in a finite element model for different angulations and depths of insertion.

Methods: A three-dimensional finite element method was used to simulate overall orthodontic tooth movements by using ANSYS software. The maxillary bone and the molars were reproduced using CT scan images and conversion of the same into STL file was done.

Comparative evaluation and influence of new Optibond eXTRa self-etch Universal adhesive and conventional Transbond XT on shear bond strength of orthodontic brackets-An in vitro study.

Introduction: The demand by dental practitioners for adhesives led to the innovation of newer self-etched universal adhesive systems. The objectives were to evaluate the shear bond strength (SBS) of metal brackets bonded with Optibond eXTRa Universal self-etch adhesive and Transbond XT primer and also to assess the adhesive remnant index (ARI).

Materials And Methods: A total of 100 extracted human premolar tooth samples were divided into 2 groups (n = 50) according to the adhesive system employed: Transbond XT (3M Unitek) and Optibond eXTRa Universal (KaVo Kerr).

"Effect of grape seed and green tea on shear bond strength of brackets bonded to bleached enamel with and without Lase Peroxide Lite" - An study.

Objective: To investigate the effect of antioxidants on shear bond strength of brackets bonded to bleached enamel with and without titanium dioxide nanoparticles (Lase Peroxide Lite).

Materials And Methods: One hundred and five human maxillary premolars were randomly divided into seven groups ( = 15). Group I served as control, in group II-A bleaching was performed with Opalescent Boost.
