Color Stability of Different Aesthetic Arch Wires in Beverages Consumed During the COVID-19 Era: An In Vitro Study.

Introduction One of the prime reasons for patients seeking orthodontic treatment is improvement in their aesthetics or appearance. With a greater number of adult patients now opting for orthodontic treatment, the demand for aesthetic orthodontic materials has increased. With the background of the recent coronavirus disease 2019 (COVID-19) pandemic and the popular role of strongly pigmented beverages that play an immunity-boosting role, studies exploring the effect of such beverages on orthodontic appliances may improve the decision-making process of selecting such aesthetic appliances.

A Novel Mobile App for Oral Cancer Awareness amongst General Population: Development, Implementation, and Evaluation.

Aim: To develop a mobile app for education and screening regarding oral cancer in the general population.

Materials And Methods: A mobile app titled Prayaas-Oral Cancer Prevention, Treatment, and Rehabilitation was designed and developed to be installed on a basic mobile handset with or without internet. It was aimed for the common public, patients as well as healthcare providers.

Correlation of calcification of permanent mandibular canine, mandibular premolars, and permanent mandibular first and second molars with skeletal maturity in Indian population.

Context: Morphological variation in children can be understood by the knowledge of growth and development. The state of dental development can be used in forensic odontology to ascertain the age of an unidentified child.

Aims: This study aims to investigate the relationship of the stages of calcification of the permanent mandibular canine, mandibular premolars, and permanent mandibular first and second molars with skeletal maturity using panoramic and hand-wrist radiographs.

Stereomicroscopic evaluation of dentinal defects induced by new rotary system: "ProTaper NEXT".

Introduction: The objective of this study was to evaluate dentinal defects formed by new rotary system - Protaper next™ (PTN).

Materials And Methods: Sixty single-rooted premolars were selected. All specimens were decoronated and divided into four groups, each group having 15 specimens.

Chondroblastic osteosarcoma of the left zygomatic bone: Rare case report and review of the literature.

Chondroblastic osteosarcoma (COS), a subgroup of intramedullary osteosarcoma (OS), is the most common osteosarcoma that occurs in adolescents and early adulthood. The COS has similar clinical and radiological features to those of conventional OS. We present a case of 20-year-old male patient with the chief complaint of pain and swelling in the left zygomatic region.

Histological patterns of head and neck tumors: An insight to tumor histology.

This article emphasizes the basis for origin and importance of tumor patterns in diagnosis of oral and maxillofacial tumors. In this article, histological patterns and subpatterns of head and neck tumors are enlisted. Although, undifferentiated tumors remain a challenge to the histopathologist, by describing the histological patterns and the subpatterns of the tumors, an attempt has been made for the diagnosis of the tumors and subsequently for implementation of precise treatment plan for the same.

Effect of various temperatures on restored and unrestored teeth: A forensic study.

Background: In large scale disasters associated with fire the damage caused by heat can make medico legal identification of human remains difficult. Teeth, restorations, and prostheses all of which are resistant to quite high temperatures and can be used as aids in identification process.

Aim: Aim of the study was to investigate the macroscopic and microscopic changes of teeth and several dental filling materials exposed to a range of high temperature (200-800°C).

Pathophysiology of merkel cell.

The objective of this review is to introduce Merkel cells (MCs), to provide a basic overview on the theoretical background of function, development and clinical importance of MCs. The origin of human MCs have been controversial. Some investigators believe that it is a neural crest derivate, whereas others have proposed that it is a differentiation product of the fetal epidermal keratinocytes.
