Added Sugar and Oral Health: A Position Paper of the Brazilian Academy of Dentistry

Knowledge, Attitudes, and Practices Associated with the Selection of Sweetened Ultra-Processed Foods and Their Importance in Oral Health

BACKGROUND

Reading nutritional labelling helps consumers select healthier food, thereby benefitting their oral health. The purpose of this study was to describe the knowledge, attitudes, and practices (KAPs) of parents and carers of children and preteens, associated with reading nutritional labelling, selecting sweetened ultra-processed foods, and their impact on oral health.

MATERIALS AND METHODS

This was a descriptive cross-sectional study in which a validated questionnaire was administered to 298 parents and caregivers of children aged 1-12 years from different districts in Villavicencio, Colombia. Participants' scores, based on the number of correct answers, were used to classify their level of KAP as low, medium, or high. In addition, the frequency of responses, the KAP levels, and the median scores were analysed. Finally, associations were determined using the chi-square test.

RESULTS

Most participants reached a medium level in terms of knowledge (41.6%) and attitudes (49.3%) and a low level in terms of practices (43.3%). An association was found between participants' level of KAPs and their socioeconomic and educational level (p < 0.05).

CONCLUSIONS

The study findings reveal inadequate KAPs associated with nutritional labelling, adequate food selection, and the importance of oral health.

Assessing the impact of oral health disease on quality of life in Ecuador: a mixed-methods study

Introduction

Globally, oral health diseases surpass all other non-communicable diseases in prevalence; however, they are not well studied in underserved regions, where accessibility to dental services and oral health education is disparately worse. In Ecuador, further research is needed to understand such disparities better. We aimed to assess the effect of oral health disease on individuals' quality of life and how social disparities and cultural beliefs shape this.

Methods

Individuals 18 or older receiving care at mobile or worksite clinics from May to October 2023 were included. A mixed-methods approach was employed, involving semi-structured interviews, Oral Health-Related Quality of Life (OHRQoL) measures, and extra-oral photographs (EOP).

Results

The sample (n = 528) included mostly females (56.25%) with a mean age of 34.4 ± 9.44. Most participants (88.26%) reported brushing at least twice daily, and less than 5% reported flossing at least once per day. The median OHRQoL score was 4 (min-max), significantly higher among individuals ≥40 years old, holding high school degrees, or not brushing or flossing regularly (p < 0.05). Identified barriers to good oral health included affordability, time, and forgetfulness. Participants not receiving care with a consistent provider reported fear as an additional barrier. Participants receiving worksite dental services reported these barriers to be alleviated. Dental providers were the primary source of oral hygiene education. Most participants reported oral health concerns, most commonly pain, decay, dysphagia, and halitosis - consistent with EOP analysis.

Discussion

Findings underscore a need for multi-level interventions to advance oral health equity.

Potential interaction of sugar intake and tobacco exposure on dental caries in adults-A cross-sectional study from the National Health and Nutrition Examination Survey

Background/purpose

We suspected that there might be an interaction between sugar intake and tobacco exposure on the risk of dental caries. The study aimed to investigate the associations of sugar intake or tobacco exposure with the risk of dental caries.

Materials and methods

This cross-sectional study obtained data of 18804 participants from National Health and Nutrition Examination Survey (NHANES) between 2011 and 2018. Weighted univariable and multivariable logistic regression models were applied to explore the associations of total sugar intake or tobacco exposure with the risk of dental caries. The relative excess risk of interaction (RERI), attributable proportion of interaction (API), and synergy index (SI) evaluated the interaction between total sugar intake and tobacco exposure on the risk of dental caries. The effect size of odds ratio (OR), and 95% confidence interval (CI) was inputted.

Results

The OR of dental caries in adults with cotinine >10 ng/mL was 1.59 (95%CI: 1.38-1.82). The increased risk of dental caries was found in people with total sugar >19.5%E compared to those with total sugar ≤19.5%E (OR = 1.55, 95%CI: 1.34-1.78). Compared to people with cotinine ≤10 ng/mL and total sugar ≤19.5%E, adults with cotinine >10 ng/mL and total sugar >19.5%E were correlated with elevated risk of dental caries (OR = 2.76, 95%CI: 2.29-3.33). The interaction indicators RERI was 0.980 (95%CI: 0.413-1.547), API was 0.355 (95%CI: 0.192-0.517), and SI was 2.250 (95%CI: 1.344-3.767).

Conclusion

There might be interaction between sugar intake and tobacco exposure on the occurrence of dental caries in adults.

A Holistic Approach for Ethics and Sustainability in the Food Chain: The Gateway to Oral and Systemic Health

Food production is a complex matter, affecting people's lives, organizations' profits, and the well-being of the whole planet, and has multifaceted ethical considerations surrounding its production, distribution, and consumption. This paper addresses the pressing need to confront ethical challenges within the food system, encompassing issues such as environmental sustainability, food security, and individual food choices for better oral and systemic health of all individuals around the globe. From agricultural practices to global trade and food waste, ethical implications are addressed across various domains, highlighting the interconnectedness of ethical decision-making in the food industry. Central themes explored include the ethical dimensions of food production methods, the impact of global trade on food ethics, and the role of individuals in making ethically informed food choices. Additionally, this paper considers the spiritual and physical significance of food, particularly through the lens of oral health as a gateway to holistic well-being. Recognizing the complexity of the food and mouth ecosystem, this paper calls for serious interventions in legislation and economics to promote ethical protocols and techniques for sustainability reasons. It emphasizes the importance of ethical considerations in food safety management systems, regulatory frameworks, and quality standards. Moreover, this paper underlines the need for a comprehensive approach to address ethical dilemmas and moral values inherent in the food industry and oral health policies, adopting the precautionary principle and ethical decision-making frameworks. This article finally aims to serve as a call to action for stakeholders across the food industry and the healthcare sector, to prioritize ethical practices, promote transparency, rearrange economic parameters, and work towards a more sustainable and equitable food system for inner and outer oral and systemic health and human sustainability for all.

Breastfeeding, consumption of ultraprocessed foods, and dental caries at 4 years of age: A birth cohort study

BACKGROUND

Cohort studies have demonstrated an association between prolonged and/or frequent breastfeeding and early childhood caries (ECC).

AIM

To investigate the association between prolonged breastfeeding and ECC at 48 months, while considering the interaction between prolonged breastfeeding and ultraprocessed foods (UPF).

DESIGN

Data from a birth cohort study conducted in southern Brazil were used (n = 3645). Poisson regression was used to evaluate the influence of breastfeeding and UPF consumption on the prevalence and experience of caries. To measure the interaction on the additive scale between breastfeeding and UPF consumption on the prevalence and experience of ECC, the relative excess risk due to interaction (RERI) was calculated.

RESULTS

Prolonged breastfeeding was associated with higher prevalence (PR = 1.82; CI:1.59-2.08) and experience (RR = 2.47; CI:1.97-3.10) of ECC. Greater prevalence (PR = 1.16; CI: 1.04-1.30) and experience of ECC (RR = 1.22; CI: 1.00-1.48) were found in children who had high consumption of UPFs. Negative RERIs were observed for the prevalence and experience of ECC (-0.25 and -0.001).

CONCLUSION

High UPF consumption and prolonged breastfeeding were associated with ECC. No interaction, however, was observed, showing that the two exposures have independent effects. To prevent ECC, policies and programs are needed to support breastfeeding until the age of 2 years and to limit the consumption of UPF.

Oral Health Knowledge, Self-Assessed Oral Health Behavior, and Oral Hygiene Practices among the Adult General Population in Croatia

OBJECTIVES

Emphasizing the significance of optimal oral health for enhancing overall well-being, this study aimed to investigate oral health knowledge, self-assessed oral health behaviors, and oral hygiene practices within the Croatian general population.

MATERIALS AND METHODS

A cross-sectional observational study was conducted online, utilizing a questionnaire collecting sociodemographic characteristics and inquiring about respondents' oral health knowledge, self-assessed oral health status, oral hygiene habits, and use of oral hygiene products. Collected data underwent both descriptive and regression analyses to unveil patterns and relationships within the dataset.

RESULTS

The respondents showed a high level of knowledge about oral health (median score 9, IQR 7.00-10.00, maximum possible score 10), with significant factors for higher knowledge being engaged in dental professions; above-average socioeconomic status; and the use of an electric brush, dental floss, and interdental brushes (p ˂ 0.05). Insufficient knowledge, on the other hand, was associated with bleeding gums and daily smoking (p ˂ 0.05). Although 69.4% of respondents considered their oral health to be very good, 32.5% reported tooth decay, and 38.2% reported tooth sensitivity. The majority (62.0%) cited regular check-ups as the reason for their last visit to the dentist, with 74.1% feeling no anxiety or discomfort during these visits. Daily toothbrush use was widespread (97.8%), but only 34.1% and 19.1% of respondents reported using floss and/or interdental brushes daily. A remarkable 69.0% of respondents indicated that low oral health literacy and low prioritization contribute to suboptimal oral health.

CONCLUSIONS

While respondents demonstrated commendable oral health knowledge, the prevalence of reported issues suggests a potential gap between perception and actual oral health status. To address this, targeted educational interventions focusing on comprehensive oral hygiene practices and debunking misconceptions should be prioritized in Croatia.

Correlation between the beverage serving activities and the dental use of health care resources of National Health Insurance for common oral diseases

Background/purpose

: Taiwanese get use to drinking hand-shaken beverages. However, excessive sugar intake is strongly associated with the occurrence of dental caries. This study evaluated the correlation between the beverage serving activities and the dental use of National Health Insurance (NHI) for common oral diseases in 2016.

Materials and methods

Data on the population, the beverage serving activities, and the dental records of NHI were obtained from the related websites of government. These data were divided by cities and counties to investigate the beverage serving activities and the dental use of NHI for common oral diseases in 2016.

Results

In Taiwan, the value of beverage consumption per person had a moderate to high positive correlation with the dental use rate, the number of out-patient visits per 1,000 people, and the medical expenses per person for common oral diseases. For dental caries, diseases of pulp & periapical tissues, and gingivitis & periodontal diseases, their Pearson’s r values were 0.52–0.61, 0.18–0.40, and 0.58–0.65, respectively. These results indicate that the higher the beverage consumption per capita, the higher the dental use per capita.

Conclusion

There is a long-term benefit for oral health and systemic health through reducing or avoiding unnecessary excessive sugar intake. Therefore, from a cost-effectiveness viewpoint, Taiwan government should develop a better oral health care policy including a health education strategy of appropriate sugar intake to prevent dental caries and other non-communicable diseases in Taiwanese people.
