Objective: This systematic review aimed to determine the differences in the caries-associated microbiota and caries experience among children with type 1 diabetes (T1D) compared to healthy children in observational studies.
Design: Registered in PROPSERO (CRD42024529842), this review involved searching four electronic databases (PubMed, Embase, Scopus and Web of Science) from inception to April 2024. Citation searching was further performed on eligible studies from the database search. Observational studies comparing the cariogenic taxa between paediatric participants (0-18 years of age) with T1D and healthy paediatric participants were included. Caries experience was analysed where available in eligible studies. Outcomes were narratively and tabularly synthesised, and meta-analysis performed where appropriate. All studies were critically appraised using the relevant Joanna Briggs Institute appraisal tool.
Results: 425 studies were identified, of which 14 studies were eligible. After assessing 534 citations, 2 additional studies were included. Overall, 16 studies (15 cross-sectional, 1 longitudinal) satisfied the inclusion criteria. Differences in cariogenic bacteria were observed when glycaemic control was considered. Children with T1D and poorer glycaemic control exhibited an increase in Streptococci and Lactobacilli taxa compared to those with improved glycaemic control and healthy children. A small number of studies also found increases in the caries experience with poorer glycaemic control.
Conclusion: Overall, the evidence indicates that children with T1D who have poorer glycaemic control exhibit an increase in cariogenic bacteria. Early evidence suggests that these children also experience more caries. However, further research with improved and longitudinal study designs are required to strengthen the existing evidence.

Background: Oral health plays an important role in the general health of pregnant women and their newborns. Our aim was to assess oral health-related quality of life and its association with oral health literacy and dental caries among a group of Iranian pregnant women.
Materials And Methods: A cross-sectional study was conducted on 200 pregnant women attending a governmental hospital in Isfahan, Iran, applying a convenient sampling method.

Objective: Dental caries is one of the most common preventable diseases among Indigenous children. The study aimed to estimate the efficacy of an Early Childhood Caries (ECC) intervention among Aboriginal Australian children over 9 years, and to explore potential risk factors associated with dental caries among Indigenous Australian children.
Methods: Data were from a randomized controlled trial conducted in South Australia, Australia.

Background: Irular and Narikuravars, are the oldest Dravidian ethnic group and a semi-nomadic community people located in Tamil Nadu. Both the indigenous groups are relegated to the margins of society and face limited access to oral health care. Thus, we aimed to assess the normative need by assessing their oral health status and risks of Narikuravar and Irular tribes residing in Villupuram District, Tamil Nadu.

Root caries is a form of decay affecting root surfaces of teeth, often exacerbated by periodontal disease, reduced salivary flow, and compromised mucosal health, all factors strongly influenced by nutrition. Despite this connection, few studies have addressed the role of vitamins in oral health. This study examines the association between serum levels of alpha-carotene (α-carotene), a potent antioxidant and proxy for vitamin A, and the experience of root caries.
