Article Synopsis
- The study aimed to investigate links between serum vitamin D levels and depressive/anxiety symptoms in women during pregnancy and after childbirth, analyzing various qualifying research studies.* -
- A total of 25 studies were included, revealing that lower vitamin D levels were significantly associated with higher rates of depressive symptoms both before and after childbirth, while only one study suggested a potential link with anxiety.* -
- The evidence presented is of low quality, indicating a need for more thorough research, particularly longitudinal studies, to better understand these relationships between vitamin D levels and mental health during and after pregnancy.*
Article Synopsis
- The study aimed to evaluate the impact of antifungal agents mixed with denture base materials on controlling Candida spp. infections and to examine the antimicrobial effects of these materials.
- A thorough search across six major databases and patent records resulted in the analysis of 40 relevant studies, primarily focusing on tissue conditioners and acrylic resins with nystatin and fluconazole being the leading antifungal agents.
- Results indicated that integrating these antifungal agents into denture materials yielded a notable inhibitory effect against Candida spp., as confirmed by various laboratory testing methods.

Objective: This study aimed to evaluate the prevalence of probable sleep bruxism (SB) in children aged 7-8 years and its association with sleep pattern and the time spent using devices with a screen.
Material And Methods: A cross-sectional study was conducted with children from Pelotas, Brazil (n = 556). Parents/caregivers were interviewed and provided demographic/socioeconomic information, children's daily screen time, nighttime tooth grinding or clenching, sleep duration and answered the Biological Rhythms Interview for Assessment in Neuropsychiatry for Kids (BRIAN-K-sleep domain).
This study summarised the association between ultra-processed food (UPF) consumption and dental caries in children and adolescents through a systematic review and meta-analysis. The search of PubMed, Cochrane, Web of Science and Scopus databases using the 'PECOS' strategy retrieved 1462 eligible articles. Only studies with humans aged ≤ 19 years; that assessed groups of any UPF or specific UPF items; that measured dental caries as the decayed, filled and missing surfaces or teeth indexes, based on the WHO criteria; cross-sectional, case-control, cohort and all types of interventions that examined the adjusted association between UPF consumption and dental caries were included.
