Alkhars N, Al Jallad N, Wu TT, Xiao J. Multilocus sequence typing of Candida albicans oral isolates reveals high genetic relatedness of mother-child dyads in early life. PLoS One 2024; 19:e0290938. [PMID: 38232064 PMCID: PMC10793898 DOI: 10.1371/journal.pone.0290938] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2023] [Accepted: 11/14/2023] [Indexed: 01/19/2024] Open
Abstract
Candida albicans is a pathogenic fungus recently recognized for its role in severe early childhood caries development (S-ECC). C. albicans oral colonization begins at birth, but the extent of the mother's involvement in yeast transmission to their children is unclear, therefore, this study used a prospective mother-infant cohort to investigate the maternal contribution of C. albicans oral colonization in early life. Oral samples were collected from 160 mother-child dyads during pregnancy and from birth to two years of life. We used whole-genome sequencing to obtain the genetic information of C. albicans isolates and examined the genetic relatedness of C. albicans between mothers and their children using Multilocus Sequence Typing. Multivariate statistical methods were used to identify factors associated with C. albicans' acquisition (horizontal and vertical transmissions). Overall, 227 C. albicans oral isolates were obtained from 93 (58.1%) of mother-child pairs. eBURST analysis revealed 16 clonal complexes, and UPGMA analysis identified 6 clades, with clade 1 being the most populated 124 isolates (54.6%). Significantly, 94% of mothers and children with oral C. albicans had highly genetically related strains, highlighting a strong maternal influence on children's C. albicans acquisition. Although factors such as race, ethnicity, delivery method, and feeding behaviors did not show a significant association with C. albicans vertical transmission, the mother's oral hygiene status reflected by plaque index (PI) emerged as a significant factor; Mothers with higher dental plaque accumulation (PI >=2) had a significantly increased risk of vertically transmitting C. albicans to their infants [odds ratio (95% confidence interval) of 8.02 (1.21, 53.24), p=0.03]. Furthermore, Black infants and those who attended daycare had an elevated risk of acquiring C. albicans through horizontal transmission (p <0.01). These findings highlight the substantial role of maternal transmission in the oral acquisition of C. albicans during early life. Incorporating screening for maternal fungal oral carriage and implementing oral health education programs during the perinatal stage may prove valuable in preventing fungal transmission in early infancy.

Abstract
The mother represents one of the earliest sources of microorganisms to the child, influencing the acquisition and establishment of its microbiota in early life. However, the impact of the mother on the oral microbiota of the child from early life until adulthood remains to unveil. This narrative review aims to: i) explore the maternal influence on the oral microbiota of the child, ii) summarize the similarity between the oral microbiota of mother and child over time, iii) understand possible routes for vertical transmission, and iv) comprehend the clinical significance of this process for the child. We first describe the acquisition of the oral microbiota of the child and maternal factors related to this process. We compare the similarity between the oral microbiota of mother and child throughout time, while presenting possible routes for vertical transmission. Finally, we discuss the clinical relevance of the mother in the pathophysiological outcome of the child. Overall, maternal and non-maternal factors impact the oral microbiota of the child through several mechanisms, although the consequences in the long term are still unclear. More longitudinal research is needed to unveil the importance of early-life microbiota on the future health of the infant.

Abstract
The oral cavity is home to the second most diverse microbiome in the human body. This community contributes to both oral and systemic health. Acquisition and development of the oral microbiome is a dynamic process that occurs over early life; however, data regarding longitudinal assembly of the infant oral microbiome is scarce. While numerous factors have been associated with the composition of the infant oral microbiome, early feeding practices (breastfeeding and the introduction of solids) appear to be the strongest determinants of the infant oral microbiome. In the present review, we draw together data on the maternal, infant, and environmental factors linked to the composition of the infant oral microbiome, with a focus on early nutrition. Given evidence that breastfeeding powerfully shapes the infant oral microbiome, the review explores potential mechanisms through which human milk components, including microbes, metabolites, oligosaccharides, and antimicrobial proteins, may interact with and shape the infant oral microbiome. Infancy is a unique period for the oral microbiome. By enhancing our understanding of oral microbiome assembly in early life, we may better support both oral and systemic health throughout the lifespan.

Abstract
INTRODUCTION Almost half of the world's children experience passive smoking, which is linked to numerous oral health conditions. The aim is to synthesize data on the impact of passive smoking on oral health of infants, preschoolers, and children. AIMS AND METHODS A search was conducted across Medline (via EBSCOhost), PubMed, and Scopus up to February 2023. Risk of bias was assessed according to the Newcastle-Ottawa Scale (NOS). RESULTS The initial search produced 1221 records and after removal of duplicates, screening by title and abstract, and full-text assessment, 25 studies were eligible for review and data extraction. The majority of studies (94.4%) found a correlation between passive smoking and increased prevalence of dental caries with three studies suggesting a dose-response relationship. Prenatal passive smoking exposure in 81.8% of studies indicated an increased dental caries experience compared to postnatal exposure. Low parental education, socioeconomic status, dietary habits, oral hygiene, and gender affected the level of environmental tobacco smoke (ETS) exposure and dental caries risk. CONCLUSIONS The results of this systematic review strongly suggest a significant association between dental caries in the deciduous dentition and passive smoking. Early intervention and education on the effects of passive smoking on infants and children will allow for the improvement in oral health outcomes and reduction in smoking-associated systemic conditions. The results justify all health professionals paying more attention to passive smoking when conducting pediatric patient histories, contributing to improved diagnosis and appropriate treatment planning with more suitable follow-up schedules. IMPLICATIONS The evidence from this review that environmental tobacco smoke and passive smoking is a risk factor for oral health conditions, both prenatally and postnatally during early childhood, justifies all health professionals paying more attention to passive smoking when conducting pediatric patient histories. Early intervention and appropriate parental education regarding the effects of secondhand smoke on infants and children will allow for the minimization of dental caries, improvement in oral health outcomes and overall reduction in smoking-associated systemic conditions for the children exposed.

Abstract
Oral health is an integral part of every child's overall wellness and affects their development, family, and social life, as well as school performance; it should be addressed at every well-child visit. Tooth decay continues to be the most prevalent yet preventable chronic disease of childhood; it leads to unnecessary pain, infections, poor academic performance, and frequent school absences and adds an unnecessary financial burden to the health care system. Despite improvements in oral health, disparities continue to exist for children from minority backgrounds and lower socioeconomic status. As primary care providers for children, it is important to understand factors that lead to oral disease and be able to anticipate, treat, and, most important, prevent oral disease in children early in their development.

Abstract
The aim of this study is to compare the efficacy of two methods for collecting saliva samples from infants under 2 years of age for cariogenic streptococci (CS) count. Two collection methods were applied in 11 infants. In Method (A), saliva samples were collected by swabbing the inner cheek mucosa and floor of the mouth in figure of eight motions with a sterile cotton swab until it was soaked. In method (B), saliva samples were collected by aspiration of 1 ml of saliva with a sterile plastic syringe on the floor of the mouth, after stimulation with glove. The samples were cultured in modified Gold's broth (MSMG), and on trypticase, yeast extract, sucrose, cystine and bacitracin culture medium (TYSCB). In method (A), the swab with the sample was unloaded in situ on TYSCB and placed in PBS medium for transport. Then, 100 μl of the eluate was seeded in MSMG. In method (B) 100 μl were seeded in TYSCB and 100 μl in MSMG. Both culture media were incubatedundercapnophilicconditions for 48 hours at 37 °C. Colony forming units (CFU/ml) were counted by calibrated operators (kappa = 0.75). The presence of cariogenic streptococci (CS) (Streptococcus mutans-Streptococcus sobrinus) was determined by qPCR in the samples collected by both methods. The CFU/ml counts in MSMG differed significantly between methods (p = 0.021). In TYSCB, the recovery of CFU/ml was higher in method (A), without significant difference (p = 0.705). The molecular technique detected presence of CS, with no difference between collection methods. Collecting saliva samples by swabbing proved more effective in terms of recovery of microorganisms, and did not affect the detection of presence of CS by molecular techniques.

Abstract
To improve oral hygiene education, we evaluated the perception and potential impact of microbiology-focused oral hygiene instructions (OHI) given to pregnant patients. Dental hygienists provided this supplemental education and administered Saliva-Check Mutans (SCM) tests to pregnant patients (n = 188) in Obstetrics and Gynecology (OB/GYN) settings. Patients reported their self-perceived understanding of the relationship between oral bacteria and dental disease and returned postdelivery to receive a second SCM test and follow-up questionnaire (n = 47). Prior to the hygienist instruction, 84% of participants understood that bacteria caused tooth decay, while only 36% understood they could transfer these bacteria to their children. After instruction, patient understanding increased to 97% and 95%, respectively. Participants attributed these increases to the hygienist’s explanation and SCM test. In postdelivery participants, >80% reported adherence to routine oral hygiene practices, and a significant decrease in patients with high-risk levels of salivary Streptococcus mutans was determined by SCM test (p = 0.0253). Participants agreed that the SCM test (89%) and microbiology explanation (95%) should be provided to every pregnant patient. Evaluation of patient perception of this intervention highlights how focused instruction on the infectious nature of dental disease can increase perinatal oral health literacy. Microbiology-focused education should be given to pregnant patients to reduce oral health disparities.

Abstract
Objective The aim of the study was to investigate the maternal-child S. mutans infection, mutual interaction and potential risk factors altering this interaction. Material and methods A total of 160 mothers who were paired with their children were recruited. Saliva from mothers and children was collected and S. mutans categorized levels were analyzed. A questionnaire was used to collect maternal and child conventional caries risk factors. A proportional odds regression model was used to investigate whether the level of infection of mothers would similarly affect the level of infection of their children, thus adjusting for other risk factors. Results The average age of mothers was 28.1 years and children had a median age of 5.1 months. Paired mother-child S. mutans cross-classification into non-infected and infected subjects showed no agreement in mutual contamination. Maternal infection of the child was highest when the mother was infected with 10>3 S. mutans/ml of saliva. The results obtained by the regression model showed that none of the potential risk factors influenced the level of infection in the child. Conclusion Mothers with a high S. mutans level increase the risk of S. mutans acquisition for her five- month- old child but no evidence was found that other maternal/child factors may influence this.

Abstract
INTRODUCTION Non-pharmaceutical measures to facilitate a response to the COVID-19 pandemic, a disease caused by novel coronavirus SARS-CoV-2, are urgently needed. Using the World Health Organization (WHO) health emergency and disaster risk management (health-EDRM) framework, behavioural measures for droplet-borne communicable diseases and their enabling and limiting factors at various implementation levels were evaluated. SOURCES OF DATA Keyword search was conducted in PubMed, Google Scholar, Embase, Medline, Science Direct, WHO and CDC online publication databases. Using the Oxford Centre for Evidence-Based Medicine review criteria, 10 bottom-up, non-pharmaceutical prevention measures from 104 English-language articles, which published between January 2000 and May 2020, were identified and examined. AREAS OF AGREEMENT Evidence-guided behavioural measures against transmission of COVID-19 in global at-risk communities were identified, including regular handwashing, wearing face masks and avoiding crowds and gatherings. AREAS OF CONCERN Strong evidence-based systematic behavioural studies for COVID-19 prevention are lacking. GROWING POINTS Very limited research publications are available for non-pharmaceutical measures to facilitate pandemic response. AREAS TIMELY FOR RESEARCH Research with strong implementation feasibility that targets resource-poor settings with low baseline health-EDRM capacity is urgently needed.

Abstract
Aim: The degree of vertical (intrafamilial) and horizontal (extrafamilial) transfer of Streptococcus mutans ( S. mutans) to a child shows differences according to cultures. The wrong care habits may result in transfer of S. mutans. The aim of this study was to determine the vertical and horizontal transmission of S. mutans to a child and effective factors. Materials and Methods: Mothers and kindergarten staff of 37 children aged between 4 and 5 years who initially started in two kindergartens (Group 1, n = 19; Group 2, n = 18) were included in this in vivo study according to 95% reliability and 80% theoretical power. Intraoral examination of mothers and children made according to the World Health Organization criteria (dmf-t/DMF-T) was done, following which mothers were asked to fill questionnaire forms including knowledge and attitudes of them about oral/dental health care. 1 mL saliva samples received from children/mothers/staff were examined microbiologically in order to isolate and quantify S. mutans. Arbitrarily primed polymerase chain reaction analysis was done to determine the genetic characteristics of S. mutans. All examinations were repeated to evaluate the horizontal transmission in the fifth month. Parametric tests ( t-test and two-way analysis of variance) were employed for comparison of the variables that meet the normality assumption and nonparametric tests (Mann–Whitney) were also used. Results: It was observed that there is a statistically significant correlation between mother DMF-T values and mother–child S. mutans similarity level ( P < .05). There is a statistically positive correlation between the habits of using a common fork, spoon, glass, and mother–child similarity level. Conclusion: Vertical and horizontal transfers occurred in Turkish families in order to prevent the transfer of S. mutans; wrong baby care habits that may lead to the transfer of S. mutans, which is the main factor in case of tooth decay, should be avoided.

Abstract
Oral microbiomes vary in cariogenic potential; these differences may be established early in life. A major concern is whether mothers transmit cariogenic bacteria to their children. Here we characterize early salivary microbiome development and the potential associations of that development with route of delivery, breastfeeding, and mother's oral health, and we evaluate transmission of microbes between mother and child. We analyzed saliva and metadata from the Center for Oral Health Research in Appalachia. For this cohort study, we sequenced the V6 region of the 16S rRNA gene and used quantitative polymerase chain reaction to detect Streptococcus mitis, Streptococcus sobrinus, Streptococcus mutans, Streptococcus oralis, and Candida albicans in the saliva from mothers and their infants, collected at 2, 9, and 12 mo (Pennsylvania site) and 2, 12, and 24 mo (West Virginia site). Breastfed children had lower relative abundances of Prevotella and Veillonella. If mothers had decayed, missing, or filled teeth, children had greater abundances of Veillonella and Actinomyces. There was little evidence of maternal transmission of selected microbes. At 12 mo, children's microbiomes were more similar to other children's than to their mothers'. Infants' salivary microbiomes became more adult-like with age but still differed with mothers' microbiomes at 12 mo. There was little evidence supporting transmission of selected microbes from mothers to children, but risk of colonization was associated with tooth emergence. Children are likely to acquire cariogenic bacteria from a variety of sources, including foods and contact with other children and adults.

Abstract
BACKGROUND Dental caries can develop early in life and have harmful consequences. Objective: To examine non-dental practitioners' knowledge of early childhood caries (ECC). METHODS A questionnaire on oral health and caries knowledge was emailed to five types of health professional who work with young children: paediatricians, GPs, midwives, paediatric nurses and paediatric healthcare assistants. Questions concerned: when a child should first visit a dentist; at what age toothbrushing should start; aetiopathogenic factors; early diagnosis; and the effect of breastfeeding. RESULTS 494 health professionals (79 paediatricians, 59 physicians, 217 midwives, 92 paediatric nurses and 47 paediatric healthcare assistants) participated. Although most (89.86%) discussed oral health with parents, responses on when a child should first see a dentist and when toothbrushing should start varied. Almost half of respondents said they could diagnose caries but not all were confident in this. Aetiological factors in ECC mentioned included oral hygiene, bottle feeding, sugar intake, genetics and a lack of fluoride. CONCLUSION Non-dental practitioners lack knowledge about ECC, so cannot help prevent it. Initiatives including interprofessional training would improve their knowledge of oral health in early childhood.

Psychosocial, education, economic factors, decision-making ability, and caries status of mothers of children younger than 6 years in suburban Nigeria. BMC Oral Health 2020; 20:131. [PMID: 32375771 PMCID: PMC7201958 DOI: 10.1186/s12903-020-01120-8] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2020] [Accepted: 04/26/2020] [Indexed: 12/12/2022] Open
Abstract
Background Little information is available on the relationship between mothers’ psychosocial profile and caries status, and less information is available on the oral health status and psychosocial status of mothers of young children in Africa. This study examined the association between the psychosocial profile of mothers in Nigeria and their prevalence of caries. Methods The prevalence of caries and severe caries (DMFT > 3) in mothers with children 71 months old and younger recruited through a household survey in Ile-Ife, Nigeria, was estimated through clinical examination. The explanatory variables were maternal education, income, decision-making status, and psychosocial status (dental anxiety, general anxiety, depressive symptoms, parenting stress, executive dysfunction, sense of coherence, fatalism and social support). The risk indicators for maternal caries were analyzed with logistic regression. Results The prevalence of caries was 3.3%. Twenty (39.2%) of the 51 women with caries had DMFT > 3. Most study participants were 25–34 years old (59.3%), had secondary level education (63.1%), earned N18,000 ($49)-N30000 ($84) per month (42.9%), and can make autonomous decisions about their health care, household purchases, or visits to family/relatives (68.8%). Most women had normal general anxiety (79.9%), low dental anxiety (90.4%), and normal stress (76.4%) levels. Most also had high fatalism (56.6%), perceived moderate social support (81.6%), had normal depressive symptoms (75.9%), low executive dysfunction (55.9%), and high sense of coherence (53.8%). Mothers who had clinically significant levels of stress were twice more likely to have caries than were those whose level of stress was normal (AOR: 2.26; 95%CI: 1.04–4.89; P = 0.039). Also, mothers who had high fatalism were less likely to have caries than were those with low fatalism (AOR: 0.40; 95%CI: 0.21–0.75; P = 0.004). Conclusion High levels of parenting stress was a risk indicator for caries while high fatalism was protective from caries in mothers of children younger than 6-years. Maternal education, income and decision-making ability were not associated with maternal caries. Though the caries prevalence for women with young children was low, the prevalence of severe caries was high and this because of the possible negative effect on their health and wellbeing.

Abstract
Improving oral health outcomes in Hawai'i for children and families remains a high priority. Children in the state are leading the nation with the highest caries rates, while women before, during, and after pregnancy are failing to receive regular and necessary dental care resulting in poor health outcomes. To answer for this need, an educational intervention was conducted among families enrolled in the Kapi'olani Medical Center for Women and Children's Women, Infant, and Children program (WIC) in O'ahu. The project included the following activities: (1) identification the oral health beliefs and behaviors of families, (2) providing oral health education to families, and (3) reassessing beliefs and behaviors in 3-6 months to document the impact of theeducation session. Participants consisted of 81 families resulting in the data on 176 children and 4 pregnant women. Of the 81 families, 40 representing84 children completed the follow-up oral health questionnaire. Results of the assessment and education demonstrated a positive impact on the family's oral health behaviors. Parents were 6.61 times as likely to report using fluoride toothpaste in the follow-up visit compared to their initial visit (95% confidence interval [CI] = 3.12-14.00). Additionally, statistically significant changes were noted in the frequency of children's daily tooth brushing (odds ratio [OR] = 2.15, 95% CI = 1.33-3.46), as well as in the incidence of children receiving fluoride varnish application over time (OR = 2.66, 95% CI = 1.50-4.73). These results provide further evidence that initiating a simple educational intervention can have a positive impact on oral health behaviors in groups that are at highest risk for developing dental disease in Hawai'i.

Abstract
Midwifery students can have an important role in transferring oral health care information to expecting mothers. The aim of this study was to assess the effect of an educational intervention on knowledge and attitudes of midwifery students on oral health in pregnancy. Study population consisted of 60 midwifery students in a Midwifery School in Iran who were randomly allocated into case and control groups. Self-administered questionnaires were distributed before, immediately after the intervention and also three months later. The validity and reliability of the questionnaire was confirmed at the beginning. Mean total pre-test knowledge scores from total 10 in the interventional and control groups were 4.63 ± 0.25 (Standard Error, SE) and 4.79 ± 0.31 (SE) respectively. After three months scores reached to 8.87 ± 0.15 (SE) in the interventional and 5.57 ± 0.29 (SE) in the control groups. Mean attitude pre-test scores in the interventional group was 27.23 ± 0.75 (SE) and after the intervention reached to 31.13 ± 0.25 (SE). Lecture-based educational intervention improved the knowledge and attitudes of midwifery students on oral health care in pregnancy. Incorporating courses on oral health in pregnancy into the curricula of midwifery programs can be effective in promoting oral health care in pregnant women.

Abstract
Objective: The aim of this study was to examine the microbiological changes in newborn babies with cleft lip palate from birth up to age 3 and to correlate them with their caries levels and mothers’ microbiological data and to compare with normal infants. Basic Research Design: Prospective. Settings: Marmara University, Faculty of Dentistry, Pediatric Dentistry Clinic, and Şişli Hamidiye Etfal Education and Research Hospital New Born Clinic. Patients/Participants: Cleft lip palate (n = 21) and healthy (n = 13) newborns and their mothers. Material and Methods: Intraoral samples were taken from babies in each group at least 3 times over the 3 years. Saliva samples of the mothers were collected just after the birth of the babies and examined microbiologically. Dental caries was noted as either present or absent. Results: The most frequent microorganisms were candida, found at birth (n = 9, 42%) in cleft palate with or without cleft lip (CP±L) group. The number of babies infected with Lactobacilli were found to be significantly higher in the CP±L group than in the control group at birth ( P = .029) and after eruption of the first primary tooth ( P = .030). Mutans Streptococci were found in 10% of babies with CP±L at birth. Initial caries was identified in 20% of the babies with an oral cleft compared with 0% of the controls after eruption of the first primary incisors. Conclusion: The results show that the CP±L babies must be considered as a group with an increased caries risk.

Abstract
Early childhood caries is a complex health care issue that has a multifactorial etiology. One aspect of this etiology is the colonization and propagation of acidogenic bacteria at an early age. There have been several bacterial species associated with caries but 1 common species is Streptococcus mutans. Here, we describe genotypic diversity and commonality of Streptococcus mutans recovered from children representing 2 groups with similar socioeconomic demographics: a Northern Plains American Indian Tribe and a Southeast Iowa population. Forty 36‐month‐old American Indian children were selected from a cohort of 239 mothers and children, and forty 2‐ to 5‐year‐old children from Southeast Iowa were selected to compare the genotypic profiles of Streptococcus mutans recovered from each child's plaque. S. mutans isolates were selected from whole mouth plaque samples; DNA was extracted and amplified via AP‐PCR to show specific genotype patterns. These patterns were compared with GelComparIIv6.5 gel analysis software. We found 18 distinct genotypes from 524 isolates; 13 of which were common between the 2 communities. Five genotypes were unique to only the American Indian children while the Southeast Iowa children harbored no unique genotypes. Although the American Indian children had some genotypes that were not present in the Southeast Iowa children, these were not widely distributed among the community. Furthermore, the levels of genotypic diversity and commonality were similar between the 2 populations. This study sets the groundwork for a comprehensive comparison of genotypes and caries among larger subsections of both populations.
