Early childhood caries epidemiology, aetiology, risk assessment, societal burden, management, education, and policy: Global perspective

Abstract: Background: This paper is a summary of the proceedings of the International Association of Paediatric Dentistry Bangkok Conference on early childhood caries (ECC) held in 3-4 November 2018. Aim: The paper aims to convey a global perspective of ECC definitions, aetiology, risk factors, societal costs, management, educational curriculum, and policy. Design: This global perspective on ECC is the compilation of the state of science, current concepts, and literature regarding ECC from worldwide experts on ECC. Results: Early childhood caries is related to frequent sugar consumption in an environment of enamel adherent, acid-producing bacteria in a complex biofilm, as well as developmental defects of enamel. The seriousness, societal costs, and impact on quality of life of dental caries in pre-school children are enormous. Worldwide data show that ECC continues to be highly prevalent, yet infrequently treated. Approaches to reduce the prevalence include interventions that start in the first year of a child's life, evidence-based and risk-based management, and reimbursement systems that foster preventive care. Conclusions: This global perspective on ECC epidemiology, aetiology, risk assessment, global impact, and management is aimed to foster improved worldwide understanding and management of ECC.

Traumatic dental injuries in Brazilian preschool children

Abstract: – The purpose of this study was to determine the prevalence and distribution of traumatic injuries to primary anterior teeth in children from zero to 6 years old, all attendees in 28 public nursery schools in Canoas (Brazil). A total of 1545 boys and girls participated in the study. The children were clinically examined for signs of trauma according to Andreasen's classification. Traumatic injuries were identified in 35.5% of children. The largest percentage of injuries was demonstrated by 3–4-year-old child, with no significant difference between boys and girls. The maxillary central incisor was the most vulnerable to injury, without differences between the right and the left side. Single tooth injury was predominant in all age groups. Crown fractures represented 83% of all traumatic injuries. Our findings emphasize the importance of encouraging parents to visit the dentist with their child at an early stage. Furthermore, parents and educators should be advised about prevention of traumatic injuries and actions to be taken in case of an accident.

WHO Global Consultation on Public Health Intervention against Early Childhood Caries.

Abstract: Early Childhood Caries (ECC) is prevalent around the world, but in particular the disease is growing rapidly in low- and middle-income countries in parallel with changing diet and lifestyles. In many countries, ECC is often left untreated, a condition which leads to pain and adversely affects general health, growth and development, and quality of life of children, their families and their communities. Importantly, ECC is also a global public health burden, medically, socially and economically. In many countries, a substantial number of children require general anaesthesia for the treatment of caries in their primary teeth (usually extractions), and this has considerable cost and social implications. A WHO Global Consultation with oral health experts on "Public Health Intervention against Early Childhood Caries" was held on 26-28 January 2016 in Bangkok (Thailand) to identify public health solutions and to highlight their applicability to low- and middle-income countries. After a 3-day consultation, participants agreed on specific recommendations for further action. National health authorities should develop strategies and implement interventions aimed at preventing and controlling ECC. These should align with existing international initiatives such as the Sixtieth World Health Assembly Resolution WHA 60.17 Oral health: action plan for promotion and integrated disease prevention, WHO Guideline on Sugars and WHO breastfeeding recommendation. ECC prevention and control interventions should be integrated into existing primary healthcare systems. WHO public health principles must be considered when tackling the effect of social determinants in ECC. Initiatives aimed at modifying behaviour should focus on families and communities. The involvement of communities in health promotion, and population-directed and individual fluoride administration for the prevention and control of ECC is essential. Surveillance and research, including cost-effectiveness studies, should be conducted to evaluate interventions aimed at preventing ECC in different population groups.

Early Feeding Practices and Severe Early Childhood Caries in Four-Year-Old Children from Southern Brazil: A Birth Cohort Study

Abstract: The aim of this study was to investigate the relationship between feeding practices in the first year of life and the occurrence of severe early childhood caries (S-ECC) at 4 years of age. A birth cohort study (n = 500) was conducted in children who were born within the public health system in Sao Leopoldo, Brazil. Feeding practices were assessed using standardized methods at 6 and 12 months of age. A total of 340 children were examined at 4 years of age. S-ECC was defined as recommended by an expert panel for research purposes: ≧1 cavitated, missing or filled smooth surfaces in primary maxillary anterior teeth or d1+ mfs ≧5. Poisson regression with robust variance was used in order to determine the early feeding practices which represent risk factors for the occurrence of S-ECC at 4 years of age. The multivariable model showed a higher adjusted risk of S-ECC for the following dietary practices at 12 months: breastfeeding ≧7 times daily (RR = 1.97; 95% CI = 1.45–2.68), high density of sugar (RR = 1.43; 95% CI = 1.08–1.89), bottle use for liquids other than milk (RR = 1.41; 95% CI = 1.08–1.86), as well as number of meals and snacks >8 (RR = 1.42; 95% CI = 1.02–1.97). Mother’s education ≤8 years was also associated with the outcome. The present study identified early feeding practices which represent risk factors for caries severity in subsequent years. These findings may contribute to developing general and oral health interventions, with special attention to families with low maternal education.

World Report on Child Injury Prevention

Abstract: Every year, around 830 000 children die from unintentional or "accidental" injuries. The vast majority of these injuries occur in low-income and middle-income countries. However, dozens of prevention strategies and programmes exist. If they were integrated into other child survival programmes and implemented on a larger scale, many of these deaths and much of the injury-related disability could be prevented. Improved health services could also go a long way in reducing the consequences of these injuries.To draw attention to this important public health problem and the possible solutions, WHO and UNICEF have produced this World report on child injury prevention with support from many experts. The report documents the magnitude, risks and prevention measures for child injuries globally –particularly for drowning, burns, road traffic injuries, falls and poisoning. The report makes seven concrete recommendations for policy-makers to improve child injury prevention. This new document is an important policy and advocacy tool for raising attention the issue and guiding action around the world.

Primer of Biostatistics

Abstract: This book attempts to achieve a difficult goal: to teach statistics to the novice so as to impart a liking and understanding of statistics. The book is geared toward a medical audience, since most examples are from the medical literature. The structure of the book consists of the following elements in each chapter: a small number of statistical rules of thumb, followed by a nontechnical explanation, a demonstration of how to work through the mechanics of doing the statistical test in question, a summary, and sample problems to be solved by the reader. (The answers, with explanations, are provided in an appendix.) Although a variety of univariate statistics are included, certain topics that are important in medical research are not. For example, there is little or no discussion of multiple regression, life-table techniques, or pooling of studies. These omissions, especially of multiple regression, are unfortunate. The Primer was derived from

Systematic review of the efficacy and effectiveness of complementary feeding interventions in developing countries.

Abstract: CRD summary This review evaluated complementary (additional to breast feeding) feeding interventions for children aged 6-24 months. The authors concluded that educational interventions and provision of fortified foods or home fortification products can improve growth and micro-nutrient status. While the review had some methodological limitations, the authors' conclusions appear generally reliable.

The global increase in dental caries. A pending public health crisis.

Abstract: A current review of the available epidemiological data from many countries clearly indicates that there is a marked increase in the prevalence of dental caries. This global increase in dental caries prevalence affects children as well as adults, primary as well as permanent teeth, and coronal as well as root surfaces. This increase in dental caries signals a pending public health crisis. Although there are differences of opinion regarding the cause of this global dental caries increase, the remedy is well known: a return to the public health strategies that were so successful in the past, a renewed campaign for water fluoridation, topical fluoride application, the use of fluoride rinses, a return to school oral health educational programs, an emphasis on proper tooth brushing with a fluoride dentifrice, as well as flossing, a proper diet and regular dental office visits. If these remedies are not initiated, there could be a serious negative impact upon the future oral health (and systemic health) of the global community, as well as a strain on the dental profession along with a major increase in the cost of dental services.
