Antineoplastic therapy is an independent risk factor for dental caries in childhood cancer patients: a retrospective cohort study.

Purpose: To evaluate the antineoplastic therapy (AT) as a risk factor for dental caries lesions independent of other risk factors such as income, family education, stimulated salivary flow rate, hygiene habits, frequency of sugar intake, and microbiota in childhood cancer (CC) patients.

Methods: 72 individuals were divided into CC patients (n=36) and healthy individuals (control group - CT n=36). Demographic data, hygiene habits, frequency of sugar intake, CC type, and AT were collected.

Antineoplastic therapy in childhood cancer patients presents a negative impact in the periodontal tissues: a cohort study.

Objectives: To investigate the effect of antineoplastic therapy (AT) in the periodontal tissues of childhood cancer (CC) patients.

Materials And Methods: Seventy-two individuals were divided into CC (n=36) and healthy individuals (control group-CG, n=36). Demographics, hygiene habits, CC type, and AT were collected.

Black Ethnicity Influences Gingival and Bone Thickness: A Cross-Sectional Study.

The present study aimed to use CBCT to compare the influence of White and Black ethnicity on gingival and bone thickness. A total of 84 individuals of both genders, aged between 18 and 59 years old, were divided into Black (BG; n = 42) and White (WG; n = 42) groups and were analyzed from June 2020 to April 2021. The gingival thickness (GT) and buccal bone plate thickness (BBPT) were measured using CBCT in all maxillary anterior teeth.

Gingival pigmentation: Concurrent assessment of distribution, intensity, and extent in a black population.

Objective: To evaluate prevalence, distribution, intensity and extent of physiologic gingival melanin pigmentation (GMP) in black individuals.

Materials And Methods: For this cross-sectional study, GMP was evaluated on digital images by three calibrated examiners, according to de Krom (distribution), DOPI (intensity) and Melanin Index (extent) classifications. Descriptive statistics, Wilcoxon, Mann-Whitney, Kruskal-Wallis, Two-way ANOVA, chi square, and K-means cluster analysis were used.

Prognostication for oral squamous cell carcinoma patients based on the tumour-stroma ratio and tumour budding.

Aims: Previous studies have demonstrated that the tumour-stroma ratio (TSR) and tumour budding are of prognostic value for oral squamous cell carcinomas (OSCCs). The aim of this study was to evaluate the prognostic significance of those histological parameters, individually and in combination, for OSCC.

Methods And Results: The TSR and tumour budding (the presence of five or more buds at the invasive front) were estimated in 254 patients with OSCC.
