Understanding Parental Emotions: Children's Dental Visits and the Separation Experience.

The presence of parents during dental treatment in children is a controversial concern in dental practice. This is because of conflicting views and practices regarding the presence of parents. Therefore, the objective of this study was to evaluate parental response to their presence/absence during their child's dental treatment and to determine the factors that would influence their decision.

Direct, indirect, post-infection damages induced by coronavirus in the human body: an overview.

Background: Severe acute respiratory syndrome Coronavirus-2 invades the cells via ACE2 receptor and damages multiple organs of the human body. Understanding the pathological manifestation is mandatory to endure the rising post-infection sequel reported in patients with or without comorbidities.

Materials And Methods: Our descriptive review emphasises the direct, indirect and post-infection damages due to COVID-19.

Retention Force of Glass Ionomer Based Luting Cements with Posterior Primary Zirconium Crowns - A Comparative in Vitro Study.

Objective: To determine the retentive force of three glass-ionomer luting cements used with prefabricated primary zirconium crowns (PPZCs) and to assess whether the retentive force was dependent on cementation material or different PPZCs brands.

Study Design: Four mandibular right second molar PPZCs were selected, one each from four manufacturers-NuSmile®ZR, Sprig Crowns, Cheng Crowns and Kinder Krowns. Silicone impressions of the outer surface of crowns were taken; stone dies prepared and reduced to fit the corresponding brand.

The prevalence of novel periodontal pathogens and bacterial complexes in Stage II generalized periodontitis based on 16S rRNA next generation sequencing.

Objective: To define the subgingival microbial profile associated with Stage II generalized periodontitis using next-generation sequencing and to determine the relative abundance of novel periodontal pathogens and bacterial complexes.

Methodology: Subgingival biofilm samples were collected from 80 subjects diagnosed with Stage II generalized periodontitis. Bacterial DNA was extracted, and 16S rRNA-based bacterial profiling via next-generation sequencing was carried out.

Interproximal contact areas of primary molars based on OXIS classification - a two centre cross sectional study.

Contact areas in primary teeth are known to be broader, flatter and situated farther gingivally than permanent teeth. The purpose of this study was to assess the prevalence of OXIS contact areas between primary molars using die models of children from two different ethnic populations. The research question of the present study is "What is the prevalence OXIS contact areas of primary molars in the populations studied?".

Dynamic measurement of the optical properties of bovine enamel demineralization models using four-dimensional optical coherence tomography.

Dental enamel mineral loss is multifactorial and is consequently explored using a variety of in vitro models. Important factors include the presence of acidic pH and its specific ionic composition, which can both influence lesion characteristics. Optical coherence tomography (OCT) has been demonstrated as a promising tool for studying dental enamel demineralization.
