This in vitro study evaluated the effects of brushing with activated charcoal powder or toothpaste on enamel surface properties, including color change (ΔE), Knoop microhardness (HK), roughness (Ra), and the characteristics of the resulting brushing slurry [pH, fluoride (F), and calcium (Ca) concentration]. A total of 48 enamel samples were stained and divided into 4 groups ( = 12): activated charcoal toothpaste (AC-T), activated charcoal powder (AC-P), hydrogen peroxide-based whitening toothpaste (HP-T), and conventional toothpaste (C-T, positive control). The samples were subjected to a brushing cycling model, and ΔE, HK, Ra and enamel morphology were analyzed at baseline (T0) and after brushing cycle (T1).

Background: This study aimed to investigate the in vitro effect of a charcoal-containing dentifrice with different toothbrush stiffness on enamel.
Methods: Four main groups were applied: distilled water, conventional fluoridated toothpaste (Colgate Total 12 Clean Mint Toothpaste), charcoal toothpaste (Colgate Total Charcoal Toothpaste) and whitening toothpaste (Colgate Total Advanced Whitening Toothpaste). Three subgroups for each toothpaste were further included according to the toothbrush bristles' stiffness (soft, medium, and hard).

Introduction: Among the wide variety of commercially oral hygiene products, activated charcoal-based toothpastes have irrupted the market, claiming multiple benefits. Although most are fluoride free, others incorporate fluoride into their formulations, yet the chemical availability and stability of fluoride in these products remain unclear. Our study aimed to assess the chemical availability and stability of fluoride in commercially fluoridated toothpastes formulated with activated charcoal.

Article Synopsis
- A systematic review was conducted to summarize the latest evidence on oral health issues in slum areas, highlighting the disease burden, perceptions, practices, and access to services in both slum and non-slum urban environments of low and middle-income countries (LMICs).
- The review included studies published from January 2000 to June 2023 and utilized comprehensive databases, focusing on empirical research that reported on oral health among slum residents.
- Out of 56 assessed articles, 23 were included in the review, primarily from Asia (57%) and Africa (39%), with a varied focus on slums and urban settings to better inform health policy.

Objectives: This study aimed to evaluate the effect of whitening toothpastes on the surface roughness and colour change of CAD-CAM materials.
Materials And Methods: A total of 96 samples (2 × 10 × 12 mm) were prepared from Cerasmart (CS) and Celtra Duo blocks. Celtra Duo samples were divided into two groups.
