Prevalence of dental carries and its association with breastfeeding duration among young children in Addis Ababa, Ethiopia.

BACKGROUND: Breastfeeding is a crucial feeding practices that significantly contributes to the healthy development of children. However, the effect of breastfeeding duration on caries risk is unclear, as different studies have found different results. This study aims to assess the prevalence of dental caries and its association with breastfeeding duration among young children aged 12-36 months in selected health facilities of Addis Ababa, Ethiopia. METHODS: A cross-sectional study among 380 children aged 12-36 months from 11 health centers in Addis Ababa was conducted. Questionnaires and dental examinations were used to collect data. Dental caries was measured by the deft (decayed-extracted-filled teeth) index. Binary logistic regression was used to assess the association between dental caries and duration of breastfeeding, after adjusting for the confounders. RESULTS: The prevalence of dental caries was 53.4% (95% CI: 48.3, 58.5%), with 13.7% having high caries and 39.7% having low caries. Breastfeeding duration was not significantly associated with dental carries, after adjusting for confounders. However, sugar intake, older age, mothers' unemployment, and not being in marital union are risk factors for dental caries development. CONCLUSIONS: Promotion of healthy diet, especially limiting intake of sugar and sweets, and integration of oral health into primary health care programs are recommended. Further research using longitudinal design or meta-analysis is recommended to establish more concise evidence on the association between breastfeeding duration and dental caries.

Development of an outcome indicator framework for a universal health visiting programme using routinely collected data.

BACKGROUND: Universal health visiting has been a cornerstone of preventative healthcare for children in the United Kingdom (UK) for over 100 years. In 2016, Scotland introduced a new Universal Health Visiting Pathway (UHVP), involving a greater number of contacts with a particular emphasis on the first year, visits within the home setting, and rigorous developmental assessment conducted by a qualified Health Visitor. To evaluate the UHVP, an outcome indicator framework was developed using routine administrative data. This paper sets out the development of these indicators. METHODS: A logic model was produced with stakeholders to define the group of outcomes, before further refining and aligning of the measures through discussions with stakeholders and inspection of data. Power calculations were carried out and initial data described for the chosen indicators. RESULTS: Eighteen indicators were selected across eight outcome areas: parental smoking, breastfeeding, immunisations, dental health, developmental concerns, obesity, accidents and injuries, and child protection interventions. Data quality was mixed. Coverage of reviews was high; over 90% of children received key reviews. Individual item completion was more variable: 92.2% had breastfeeding data at 6-8 weeks, whilst 63.2% had BMI recorded at 27-30 months. Prevalence also varied greatly, from 1.3% of children's names being on the Child Protection register for over six months by age three, to 93.6% having received all immunisations by age two. CONCLUSIONS: Home visiting services play a key role in ensuring children and families have the right support to enable the best start in life. As these programmes evolve, it is crucial to understand whether changes lead to improvements in child outcomes. This paper describes a set of indicators using routinely-collected data, lessening additional burden on participants, and reducing response bias which may be apparent in other forms of evaluation. Further research is needed to explore the transferability of this indicator framework to other settings.

Prevalence and risk indicators of early childhood caries among toddlers in Caloocan City, Philippines: a cross-sectional study.

BACKGROUND: Limited published data exist on early childhood caries (ECC) among children 2 years old and below. The study aimed to determine ECC prevalence and its association with socio-demographic indicators, feeding practices and oral health behaviours among children aged 2 years and below in the Philippines. METHODS: A cross-sectional study observed young children aged 4-24 months in primary health centers. Each child's caregiver was interviewed and dental examinations were done on every child by one calibrated dentist using the ICDAS. Poisson regression using robust variance estimator analysis identified significant variables associated with ECC. RESULTS: Seven hundred three healthy children were observed at a mean age of 13.3 ± 2.4 months. ECC prevalence was 29.2% (95% confidence interval: 26.0-32.7) among toddlers who showed a mean number of 6.7 ± 3.1 erupted teeth. Multiple regression revealed that child's age (prevalence ratio, PR = 1.07), caregiver's educational level (PR = 1.43), continued breastfeeding (PR = 1.36), frequent eating (PR = 1.24), visible plaque observed by the caregiver (PR = 1.34) and in the oral examination (PR = 2.90) were significant to ECC prevalence. CONCLUSIONS: ECC is alarmingly prevalent in toddlers, marked by early onset and untreated decay. Prioritizing preventive measures in the first two years of life is crucial for understanding dietary impacts and promoting oral hygiene.

Influence of pacifier use on the association between duration of breastfeeding and anterior open bite in primary dentition.

BACKGROUND: The literature is controversial with regard to the association between longer breastfeeding duration and lower prevalence of anterior open bite. Pacifier use may be involved in this controversy. Thus, the objective of the study was to assess the influence of pacifier use and its duration on the association between longer breastfeeding duration and lower prevalence of anterior open bite in children with primary dentition. METHODS: This was a cross-sectional study nested in a cohort study involving 153 infants recruited at a maternity hospital in the municipality of Porto Alegre, southern Brazil. The study outcome (anterior open bite) was assessed when the children were between 3 and 5 years old. Data on breastfeeding and pacifier use were collected at 7, 30, 60, 120, and 180 days of life and on the date of the evaluation here described. Poisson regression with robust variance was used to analyze the association between the prevalence of anterior open bite and breastfeeding duration, expressed in months. RESULTS: The univariate analysis showed a protective effect of breastfeeding against anterior open bite (prevalence ratio [PR] 0.96; 95% confidence interval [95%CI] 0.95-0.98). This effect remained significant after adjustment for pacifier use at any time between birth and the date of dental assessment (PR0.98; 95%CI; 0.96-0.99), i.e., there was a reduction of 2% in the prevalence of anterior open bite for each month of breastfeeding. However, this effect lost significance when pacifier use duration was included in the multivariate analysis (PR1.00; 95%CI; 0.99-1.01). CONCLUSIONS: Pacifier use duration influences the association between longer breastfeeding duration and lower prevalence of anterior open bite. It is likely that prolonged pacifier use reduces the magnitude of this association.

Maternal postpartum feeding anxiety was associated with infant feeding practices: results from the mother-infant cohort study of China.

BACKGROUND: Maternal feeding anxiety (FA) was prevalent during puerperium and might affect infant feeding practices. This study was aimed to investigate the FA status in Chinese postpartum women and its relationship with infant feeding practices (FPs). METHODS: Participants were from the Mother-Infant Cohort Study of China, in which the dietary and feeding practices, physical and psychiatric health for both mothers and infants were followed up from childbirth to next 2 years. In this study the maternal feeding anxiety (FA) status at 0-3 months postpartum was assessed by Li's Self-rating Feeding Anxiety Scale (SFAS). Infant feeding practices (FPs) at 0-3 months, including breastfeeding-related behaviors, responsive feeding and infant food refusal were investigated by self-designed questionnaire. RESULTS: In total 456 mothers the average feeding anxiety scores (FAS) was 41.02 ± 8.02 (mean ± SD), and maternal FA prevalence were 61.4% (FAS>38) with severe FA being 8.6% (FAS>52) at 0-3 months postpartum. The FAS was related with infant FPs, and lower maternal FAS was significantly related with infant colostrum feeding (40.86 ± 8.02 vs 44.74 ± 11.33, P < 0.05), but higher FAS was related with bottle feeding (41.95 ± 8.28 vs 39.69 ± 7.92, P < 0.05). The mothers with severe feeding anxiety (FAS > 53) were more likely to feed infants with bottle (ORs, 95%CI: 2.41, 1.11 ~ 5.19). There were not significant association between FAS and exclusive breastfeeding and responsive feeding practices (P > 0.05). The higher FAS was associated with infant food refusal behaviors, the maternal scores whose infant "never", "rarely", "sometimes" and "often" spat out food when feeding were 39.86 ± 8.02, 41.47 ± 8.18, 41.36 ± 7.44 and 42.14 ± 12.03 increasingly (P > 0.05), and the FA prevalence was significantly different among groups (P < 0.05). The infants whose mother was identified as feeding anxiety were more likely to refuse opening the mouth when feeding (P < 0.05). Multivariate analysis indicated maternal FAS was positively related to infant bottle feeding (ßi = 2.487, P < 0.05) and outdoor sunshine exposure practice (ßi = 1.787, P < 0.05), and negatively related to household income level (ßi = - 0.118, P < 0.05). CONCLUSIONS: Maternal postpartum feeding anxiety was associated with some infant feeding practices, including bottle feeding and infant food refusal behaviors.

Nutritional and non-nutritional habits and occurrence of malocclusions in the mixed dentition.

Malocclusions are changes in the development of craniofacial structures of high prevalence. Associated risk factors are diverse and nutritional and non-nutritional suction habits are the most reported. The aim of this study was to estimate the prevalence of malocclusions in the mixed dentition and to study possible association with practices of breastfeeding and suction habits among Brazilian schoolchildren. A cross-sectional study involving a sample of 664 6-year-old children and their families was carried out. Data collection was done through interviews with mothers in the homes and oral examinations of children in schools. Multivariate analyses were performed using the Poisson regression with a robust estimator. The prevalence of overjet over 4 mm was 21.1% and of posterior crossbite was 12.2%; 91.9% of the children were breastfed, 79.0% used a nursing bottle and 49.4% used a pacifier. Significant and independent associations were observed between father's unemployment, private school, interruption of breastfeeding before the fourth month and pacifier use with certain malocclusions. High rates of malocclusion were found in the studied sample. Socioeconomic conditions, breastfeeding practices and suction habits were shown to be statistically associated with their occurrence.

Bottle-feeding an infant feeding modality: An integrative literature review.

Bottle-feeding is an infant feeding modality that has been in existence since ancient times, and currently, a significant number of infants are being fed via a bottle with either breastmilk or formula. Although research on bottle-feeding has continued, it exists in fragmented, often small studies that focus on singular aspects of feeding an infant using a bottle, with limited information on the bottle-feeding act. Systems theory was the approach used to define the act of bottle-feeding and identify the parts within this act. Health databases were searched using MeSH terms. A summary of the studies are included. The findings of this review revealed that healthy term bottle-feeding infants use similar tongue and jaw movements, can create suction and sequentially use teat compression to obtain milk, with minimal differences in oxygen saturation and SSB patterns, when compared with breastfeeding infants. Bottle and teat characteristics were revealed to affect infant feeding and milk intake. An infant's milk intake during feeding was shown to have a strong association with the interaction between the infant and parent/caregiver. With the issue of who controls the feed, mother or infant, likely to affect an infant's ability to self-regulate their milk intake. Redefining bottle-feeding as a holistic system identifies the interrelationship of the various parts which will improve the understanding of the reciprocal nature of infant feeding. To optimize bottle-feeding outcomes, further research is required on parents' and health professionals' knowledge and understanding of the parts within the act of bottle-feeding.

The role of tongue-tie in breastfeeding problems-A prospective observational study.

AIM: We evaluated what determined breastfeeding problems in a non-selected mother-infant cohort, with special reference to tongue-tie and improvements in breastfeeding following frenulotomy. METHODS: This 2014-2015 prospective, observational study was carried out in a tertiary level maternity unit affiliated to the University of Freiburg, Germany, using a breastfeeding questionnaire, standardised breastfeeding scores and the Assessment Tool For Lingual Frenulum Function (ATLFF). The standard intervention was breastfeeding support, a frenulotomy for tongue-tie was performed if necessary. All cases of breastfeeding problems and, or tongue-tie, were followed up by telephone 2.5 weeks after birth. RESULTS: We enrolled 776 newborn-mother dyads: 345 had breastfeeding problems, 116 had a tongue-tie and 30 underwent a frenulotomy. In the multivariate analysis, severe breastfeeding problems were more frequent in newborn infants with tongue-tie, with an odds ratio (OR) of 2.6 (P= 0.014). Other risk factors were: no breastfeeding experience (OR 4.4, P = 0.001), low birth weight (OR 2.9, P = 0.001), prematurity (OR 3.6, P = 0.000) and Caesarean section (OR 1.6, P = 0.023). There was a significant reduction in breastfeeding problems after frenulotomy (P = 0.01). CONCLUSION: Tongue-tie had a significant impact on breastfeeding and so did low birth weights and prematurity. Frenulotomy proved helpful when breastfeeding problems were reported.

Lactation Outcomes in More Than 3500 Women Following Primary Augmentation: 5-Year Data From the Breast Implant Follow-Up Study.

BACKGROUND: Women with breast implants may have concerns about their ability to successfully breast-feed. The Breast Implant Follow-up Study (BIFS-001) is a large, 10-year observational study evaluating the performance and safety of Natrelle round silicone gel-filled breast implants. OBJECTIVES: This analysis compared lactation outcomes in women enrolled in BIFS-001 who gave birth after they underwent primary augmentation with Natrelle round silicone implants or saline implants. METHODS: At baseline and annually after surgery (>5-year visit window), patients completed questionnaires regarding pregnancy and lactation. Comparisons were made using summary statistics and odds ratios with 90% confidence intervals (OR [90% CI]). RESULTS: A total of 4679 subjects gave birth at least once after primary augmentation for a total of 5736 live births during the study (silicone, 3695 births; saline, 2041 births). Of these, 3715 (79.4%) women breast-fed at least 1 child, resulting in 80.0% (silicone) and 75.9% (saline) of babies being breast-fed. The most common complication was insufficient milk production, which was reported for 19.6% (silicone) and 19.8% (saline) of single births (OR, 0.94 [0.83, 1.06]). Complications occurred at similar rates in each group when evaluated by incision type, implant size, pocket location, and age. CONCLUSIONS: In this large group of women who gave birth after primary breast augmentation with Natrelle round silicone implants or saline implants, most were able to breast-feed their infants without complications. Lactation complications were comparable between the silicone and saline cohorts, and the incidence was comparable to reports in the general population of women who breast-feed.

Influence of mode of delivery, family and nursing determinants on early childhood caries development: a prospective cohort study.

INTRODUCTION: Conflicting results exist regarding mode of delivery and caries. We investigated the influence of the mode of delivery and selected family- and nursing factors during the first 2 years of life on the prevalence of dental caries at 5 years. MATERIALS AND METHODS: 551 infants were invited to a prospective medical study with focus on growth and overweight prevention. The parents of 346 infants (179 boys and 167 girls) accepted this invitation and at the age of 2-years, 336 of them agreed to dental check-ups and salivary samplings. At the ages of three and five years, 302 (90%) and 292 children (87%) could be re-examined with respect to caries by one of two calibrated examiners. All stages of caries lesions were scored on tooth and surface level. Background maternal and nursing data were collected semiannually through validated questionnaires and interviews. RESULTS: The caries prevalence (initial + cavitated lesions) was 5.6% at 3 years of age and 18.9% at 5 years. The 5-year-olds delivered with caesarian section displayed a significantly elevated risk of having caries (relative risk [RR] 2.2; 95% confidence interval (CI) 1.4-3.6; p < .05). Parental smoking and siblings with caries were the most influential family determinants (p < .05) while drinking juice to meals at 2 years of age (p < .05) was most outstanding among the nursing factors (p < .05). CONCLUSIONS: In this cohort, the mode of delivery (caesarian section) had a significant impact on the risk of early childhood caries (ECC) but also other family and infant nursing determinants were related to the development of the disease.

Perinatal health and malocclusions in preschool children: Findings from a cohort of adolescent mothers in Southern Brazil.

INTRODUCTION: Pregnancy in adolescence has long-term consequences that can negatively influence oral conditions. In this study, we aimed to assess malocclusion in deciduous dentition and its association with prolonged breastfeeding, pacifier use, and perinatal health indicators pertaining to the periods immediately before and after birth. METHODS: This cross-sectional study was nested in a cohort of adolescent mothers who became pregnant from 13 to 19 years of age (mean age, 17.3 ± 1.6 years). A total of 509 mother-child dyads were included. Information on perinatal indicators, including Apgar score (0-10), which is a standardized assessment of the condition of the infant at birth (heart rate, breath rate, muscle tone, reflex irritability, and skin color), head circumference, birth weight, and need for intensive care unit admission were collected after delivery through interviews with the mothers. By the time the children were 24 to 36 months of age, malocclusion was assessed, and information on the use of pacifiers and breastfeeding was collected. Multivariate Poisson regression was used to assess the effect of independent variables on the outcome (malocclusion). RESULTS: The prevalence of malocclusion was 62.33%, and open bite was the most frequent one (47.45%). After adjustments, children with no need for intensive care unit admission had a lower risk of malocclusion (prevalence ratio [PR] = 0.75; 95% CI, 0.56-0.99), whereas those with an Apgar score less than 7 had a higher risk (PR = 1.32; 95% CI, 1.06-1.64). Children who had used a pacifier (PR = 1.82; 95% CI, 1.02-3.24) or were still using it (PR = 3.88; 95% CI, 2.65-5.68) had a higher chance of malocclusion compared with children who never used a pacifier. Children breastfeeding for 24 months or longer were less likely to have malocclusion (PR = 0.46; 95% CI, 0.34-0.73). CONCLUSIONS: Poor perinatal health and pacifier use may be risk factors for malocclusion development in deciduous teeth. Long duration of breastfeeding is associated with better occlusal conditions in children of adolescent mothers. Further studies are needed with other age groups.

Effect of restricted pacifier use in breastfeeding term infants for increasing duration of breastfeeding.

BACKGROUND: To successfully initiate and maintain breastfeeding for a longer duration, the World Health Organization's Ten Steps to Successful Breastfeeding recommends total avoidance of artificial teats or pacifiers for breastfeeding infants. Concerns have been raised that offering the pacifier instead of the breast to calm the infant may lead to less frequent episodes of breastfeeding and as a consequence may reduce breast-milk production and shorten duration of breastfeeding. OBJECTIVES: To assess the effect of restricted versus unrestricted pacifier use in healthy full-term newborns whose mothers have initiated breastfeeding and intend to exclusively breastfeed, on the duration of breastfeeding, other breastfeeding outcomes and infant health. SEARCH METHODS: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 June 2016) and reference lists of retrieved studies. SELECTION CRITERIA: Randomised and quasi-randomised controlled trials comparing restricted versus unrestricted pacifier use in healthy full-term newborns who have initiated breastfeeding. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. The quality of the evidence was assessed using the GRADE approach. MAIN RESULTS: We found three trials (involving 1915 babies) for inclusion in the review, but have included only two trials (involving 1302 healthy full-term breastfeeding infants) in the analysis. Meta-analysis of the two combined studies showed that pacifier use in healthy breastfeeding infants had no significant effect on the proportion of infants exclusively breastfed at three months (risk ratio (RR) 1.01; 95% confidence interval (CI) 0.96 to 1.07, two studies, 1228 infants), and at four months of age (RR 1.01; 95% CI 0.94 to 1.09, one study, 970 infants, moderate-quality evidence), and also had no effect on the proportion of infants partially breastfed at three months (RR 1.00; 95% CI 0.98 to 1.02, two studies, 1228 infants), and at four months of age (RR 0.99; 95% CI 0.97 to 1.02, one study, 970 infants). None of the included trials reported data on the other primary outcomes, i.e. duration of partial or exclusive breastfeeding, or secondary outcomes: breastfeeding difficulties (mastitis, cracked nipples, breast engorgement); infant's health (dental malocclusion, otitis media, oral candidiasis; sudden infant death syndrome (SIDS)); maternal satisfaction and level of confidence in parenting. One study reported that avoidance of pacifiers had no effect on cry/fuss behavior at ages four, six, or nine weeks and also reported no effect on the risk of weaning before age three months, however the data were incomplete and so could not be included for analysis. AUTHORS' CONCLUSIONS: Pacifier use in healthy term breastfeeding infants, started from birth or after lactation is established, did not significantly affect the prevalence or duration of exclusive and partial breastfeeding up to four months of age. Evidence to assess the short-term breastfeeding difficulties faced by mothers and long-term effect of pacifiers on infants' health is lacking.

Prevalence and Predictors of Early Childhood Caries in 3- to 6-year-old South Indian Children--A Cross-sectional Descriptive Study.

PURPOSE: To determine the prevalence and potential risk factors of ECC in 3- to 6-year-old preschool children. MATERIALS AND METHODS: A sample of 477 preschool children aged 3 to 6 years was randomly selected from the schools in the area of study. Caries was recorded according to the WHO criteria from 1997. Information regarding demographic data, socioeconomic status, feeding habits, oral hygiene practices, birthweight and the children's visits to the dentist was obtained through a structured questionnaire. The data were analysed using Student's t-test, the chi-square test and Pearson's correlation analysis. RESULTS: The prevalence of early childhood caries in 3- to 6-year-old preschool children was found to be 27.3% with a mean dmft of 2.36. ECC increased significantly with age and is more predominant in girls. The maxillary arch was more affected than mandibular arch and children belonging to the low socioeconomic group showed higher caries prevalence. ECC is more prevalent in children accustomed to on-demand breast feeding, bottle feeding at night, between-meal snacking and sweetened pacifier use. Factors such as increased frequency of toothbrushing, use of toothbrush and fluoridated dentifrice were found to be the protective factors against the risk of ECC. CONCLUSION: A strong correlation between the risk factors studied and ECC was found. Health education, proper guidelines on feeding and oral hygiene practices and access to early oral health care can substantially reduce the risk and prevalence of ECC.

[Effects of breast-feeding duration, bottle-feeding duration and oral habits on the occlusal characteristics of primary dentition].

OBJECTIVE: To assess the effects of breast-feeding duration, bottle-feeding duration and oral habits on the occlusal characteristics of primary dentition in 3-6-year-old children in Beijing. METHODS: This cross sectional study was conducted via an examination of the occlusal characteristics of 734 children combined with a questionnaire completed by their parents/guardians. The examination was performed by a single, previously calibrated examiner and the following variables were evaluated: presence or absence of deep overbite, open bite, anterior cross bite, posterior cross bite, deep overjet, terminal plane relationship of the second primary molar, primary canine relationship, crowding and spacing. Univariate analysis and multiple Logistic regressions were applied to analyze the associations. RESULTS: It was found that a short duration of breast-feeding (never or ≤6 months) was directly associated with posterior cross bite (OR=3.13, 95%CI=1.11-8.82, P=0.031) and no maxillary space (OR=1.63, 95%CI=1.23-2.98, P=0.038). In children breast-fed for ≤6 months, the probability of developing pacifier-sucking habits was 4 times that for those breast-fed for >6 months (OR=4.21, 95%CI=1.85-9.60, P=0.000 2). The children who were bottle-fed for over 18 months had a 1.45-fold higher risk of nonmesial step occlusion and a 1.43-fold higher risk of class II canine relationship compared with those who were bottle-fed for 6-18 months. Non-nutritive sucking habits were also found to affect occlusion: a prolonged digit-sucking habit increased the probability of an anterior open bite, while a pacifier-sucking habit was associated with excessive overjet and absence of lower arch developmental space. Tongue-thrust habit was associated with anterior open bite (OR=4.21, 95%CI=1.85-9.60, P=0.000 2) and posterior cross bite (OR=7.24, 95%CI=1.30-40.13, P=0.024). Lower lip sucking habit was associated with deep overjet and had a negative association with class III canine relationship. Unilateral chewing was associated with spacing in mandibular (OR=1.57, 95%CI=1.03-2.41, P=0.037). Mouth breathing was associated with chronic rhinitis and adenoidal hypertrophy and had an association with spacing in maxillary. The chi-square test did not indicate a statistically significant association between upper lip sucking habit and any occlusal characteristics. CONCLUSION: Breast-feeding duration was shown to be associated with the prevalence of posterior crossbite, or no maxillary space in the deciduous dentition and development of a pacifier-sucking habit. Children who had a longer duration of bottle-feeding were more likely to develop class II canine relationship. Children who had an oral habit were more likely to develop abnormal occlusal characteristics.

The Role of Feeding Practices as a Determinant of the pufa Index in Children with Early Childhood Caries.

OBJECTIVE: To evaluate the prevalence and severity of untreated dental caries among young children (aged <6 years) with early childhood caries (ECC) using the pufa index and to examine the relationship between caries and feeding practices. STUDY DESIGN: A cross-sectional study of children with ECC was undertaken in two stages: a questionnaire survey based on interviews and an intraoral examination using the defs and pufa indices. RESULTS: The overall prevalence of untreated dental caries in our sample of 238 ECC-affected children was 72.3%. The abscess component (code a) was the most common condition. There was an increase in the ECC patterns and the severity of untreated dental caries with increasing age for all teeth groups. ECC and untreated caries lesions for the various teeth groups and study sites varied inversely with current feeding status. The majority of the children had posterior ECC, and the fewest were affected by ulceration (code u) as a consequence of untreated dental caries. Except for the posterior caries pattern, all other caries patterns and pufa components (code u alone, p<0.05) had a significantly higher prevalence among children with nocturnal feeding practices (p<0.001). Binary logistic regression analyses revealed that older age (p<0.05) and nocturnal feeding practices (p<0.001) were significantly associated with pufa scores>0. CONCLUSION: These data provide valuable evidence of the effect of nocturnal feeding as an important determinant of the increased prevalence of untreated caries lesions among children with ECC.

Evaluation of Possible Associated Factors for Early Childhood Caries and Severe Early Childhood Caries: A Multicenter Cross-Sectional Survey.

OBJECTIVES: The present study evaluated associated factors for developing early childhood caries (ECC) and Severe-ECC (S-ECC) in a group of children aged 24-71 months. Potential positive effects of early dental visit on formation of ECC is investigated as well. STUDY DESIGN: This was a multicenter, cross-sectional study conducted at three governmental and university pediatric dentistry clinics in 408 preschool children who were randomly selected from a total of 4116 children. The questionnaires administered to the mothers by interview and intraoral examination performed by calibrated pediatric dentists. The children were evaluated in three groups according to their caries experience as who had caries free, ECC and S-ECC. RESULTS: The following factors were significantly associated with caries formation: 1. Prolonged (i.e., >18 months) breastfeeding in preterm babies (OR=2.4) 2. Prolonged breastfeeding in children who started tooth brushing after 1.5 years of age (OR=3.7), 3. Sugar (p<0.001) and fruit-juice consumption (p<0.0001), and 4. Lack of periodic dental examination (p<0.05). Parental smoking habit does not significantly affect ECC development. Nocturnal bottle feeding and nocturnal feeding also affected S-ECC formation significantly (p=0.043 and p=0.005, respectively). CONCLUSIONS: There is a significant difference between the children with caries and caries-free associated with the brushing initiation age started before or after 18 months. If a child is under the risk of multiple caries factors, it is very difficult to evaluate which habits affect the caries formation or increase the severity of the caries lesions.

Factors Associated with the Occurrence of Distoclusion in the Primary Dentition: A Hierarchical Analysis.

OBJECTIVE: The aim of the present study was to identify factors associated with the occurrence of distoclusion among preschool children in southern Brazil. STUDY DESIGN: A cross-sectional study was carried out with a sample of 1026 children aged two to five years enrolled at public preschools in the city of Canoas, Southern Brazil. Interviews were held with parents/caregivers to acquire demographic, socioeconomic and behavioral data. Six examiners who had undergone a training and calibration exercise performed the oral examinations. Distoclusion was recorded when the cusp of the maxillary canine was in an anterior relation to the distal surface of the mandibular canine during centric occlusion. Statistical analysis involved simple and multivariate Poisson regression with robust variance. RESULTS: The prevalence of distoclusion was 36.5% (375/1026). This condition was more frequent in younger children, those classified as white or brown, those who were breastfed for a shorter period of time, those who used a pacifier and those who were bottle fed. The multivariate analysis demonstrated that the likelihood of exhibiting distoclusion was greater among two-year-olds (P=0.038), three-year-olds (P=0.023), those classified as white (P=0.016), those who used a pacifier (P<0.001) and those who used to use a pacifier (P<0.001). CONCLUSION: Counseling with regard to the duration of pacifier use could contribute toward reducing the prevalence of distoclusion and its consequences in preschool children.

Maternal Allostatic Load, Caretaking Behaviors, and Child Dental Caries Experience: A Cross-Sectional Evaluation of Linked Mother-Child Data From the Third National Health and Nutrition Examination Survey.

OBJECTIVES: We evaluated the associations between chronic maternal stress measured by allostatic load (AL), maternal caretaking behaviors, and child dental caries experience. We also assessed the role of socioeconomic status in these associations. METHODS: We used data from the Third National Health and Nutrition Examination Survey (1988-1994). We included children aged 2 to 6 years who linked to a maternal record (n = 716 maternal-child pairs). The main exposure was maternal AL index (0, 1, or ≥ 2). The primary outcome of interest was child dental caries experience (none or any). We evaluated the association between maternal AL and (1) maternal caretaking behaviors, and (2) child caries status and the role of socioeconomic status in these relationships. RESULTS: Children of mothers with an AL index of at least 2 were significantly more likely to have not been breastfed and to have dental caries than were children of mothers with a normal AL before adjusting for measures of socioeconomic status. CONCLUSIONS: Maternal chronic stress, indicated by elevation in markers of AL, has an important role in child caretaking behaviors and in children's oral health.

Association between nocturnal breastfeeding and snacking habits and the risk of early childhood caries in 18- to 23-month-old Japanese children.

BACKGROUND: Early childhood caries (ECC) is one of the most prevalent chronic diseases among children. The aim of this cross-sectional study was to investigate the association between nocturnal breastfeeding, snacking habits, or other risk factors and ECC in 18- to 23-month-old Japanese children. METHODS: Study subjects were 1675 children aged 18 to 23 months. A self-administered questionnaire was completed by parents or guardians of the children. The survey contents included such things as number of decayed, missing, and filled teeth per child, smokers in the home, nocturnal breastfeeding habit, snack times, kinds of snacks consumed ≥ 4 days a week, kinds of drinks consumed ≥ 4 days a week, parents brushing their child's teeth daily, and the use of fluoride toothpaste. Logistic regression analysis was performed to estimate the odds of ECC. RESULTS: The average number of decayed, missing and filled teeth was 0.10. The prevalence of dental caries was 3.3%. Nocturnal breastfeeding habits were reported in 357 subjects (21.3%). After excluding items of multicollinearity, significant associations were observed between ECC and nocturnal breastfeeding, drinking or eating sweets after dinner every day, and the intake of candy, soda and/or isotonic drinks ≥ 4 days a week. CONCLUSIONS: This study suggests that nocturnal breastfeeding and snacking habits are correlated with ECC.

Prolonged pacifier use during infancy and smoking initiation in adolescence: evidence from a historical cohort study.

AIM: To investigate the association between prolonged pacifier use during childhood and smoking in adolescence and early adulthood. METHODS: A historical cohort study including patients from a dental private office was designed. Dental records were used, which contained complete data about sucking habits from 314 children (2-10 years of age) who had attended a private dental office from 1988 to 1994 in Ibiá, Brazil. Then, we collected data about the smoking habits from 261 subjects who were successfully contacted again from 2004 to 2006. Our outcome variable was smoking, and subjects who had smoked more than 100 cigarettes during their lifetime were classified as smokers. Poisson regression analysis matched the association between oral habits and smoking. Incidence rate ratios (IRR) and 95% confidence intervals (95% CI) were calculated. The level of significance was set at 5%. RESULTS: We observed a statistically significant association between prolonged pacifier use (more than 24 months) and smoking (IRR = 4.48; 95% CI 2.32-8.65). Breastfeeding, in contrast, was a protective factor (IRR = 0.64; 95% CI 0.42-0.96). CONCLUSIONS: Prolonged pacifier use during childhood is positively associated with smoking initiation in adolescence and early adulthood.
