Concentrations of fluoride in water and plasma for US children and adolescents: Data from NHANES 2013 –2014

This study was undertaken to investigate how fluoride concentrations vary in water and plasma with age, gender, race/ethnicity, housing ownership, use of prescription fluoride drops and/or tablets, exposure to environmental tobacco smoke, and recent use of tobacco products (among adolescents). Fluoride concentrations in water were found to be lower among those aged 3-5 years than those aged 6-11 years (p=0.02), lower for non-Hispanic Asians than Hispanics (p=0.04) among 3-5 years old, lower for non-Hispanic Asians than non-Hispanic blacks (p=0.04) among 6-11 years old, and lower for those who used prescription fluoride drops and/or tablets than those who did not (p≤0.048) among 3-19 years old. Adjusted fluoride concentrations in plasma were found to be lower for females than males (p<0.01) among those aged 6-11 years, lower for Hispanics than non-Hispanic whites (p<0.01) among those aged 12-19 years, and lower for those who used prescription fluoride drops and/or tablets than those who did not (p=0.03) among 12-15 years old. Recent smokers were found to have higher fluoride concentration (p=0.03) in plasma than non-smoker adolescents. Over 60% of the children aged 6-11 years and adolescents aged 12-19 years were at the risk of developing dental caries/decay. About 30% of the children were at the risk of dental fluorosis.

In this study, we aimed to specifically elucidate the role of C. albicans-derived polysaccharide biofilm matrix components in augmenting S. mutans colonization and mixed biofilm formation. Comparative evaluations of single and mixed species biofilms demonstrated significantly enhanced S. mutans retention in mixed biofilms with C. albicans. Further, S. mutans single species biofilms were enhanced upon exogenous supplementation with purified matrix material derived from C. albicans biofilms. Similarly, growth in C. albicans cell-free spent biofilm culture media enhanced S. mutans single species biofilm formation, however, th...

Abstract Prevention and health promotion are considered important strategies to control oral diseases. Dental caries is preventable disease and remains the most common chronic disease that affects mainly low income children and still considered the main cause of tooth loss in adulthood in Brazil. The aim of this study is to present a System Dynamics model (SDM) specifically developed with the Stella Architect software to estimate the cost and clinical hours required to control the evolution of dental caries in preschool children in Maring á, Brazil. Two main strategies to control caries were considered in the model:...

ConclusionsThe mean cost of a child avoiding any dental pain and/or infection (incidence) was £330 and the mean cost per episode of dental pain and/or infection avoided was £130. At these thresholds B + P has the highest probability of being considered cost-effective. Over the willingness to pay thresholds considered, the probability of B + P being considered cost-effective nev er exceeded 75%.

Abstract Human dentine is a mineralised dental tissue that consists of dentinal tubules surrounded by two distinct dentinal phases: peritubular dentine (PTD) and intertubular dentine (ITD). Dental caries, which manifests itself as a consequence of demineralisation, is one of the most common chronic diseases that affect the function of human teeth. Due to the difference in the packing density of crystallites, PTD and ITD exhibit different reaction rates to acid dissolution. The present study evaluates how the effective Young's modulus degrades and how the effective stress redistributes in demineralised human dentin...

Therefore, it is necessary to implement oral management strategies prior to the initiation of radiotherapy in patients with head ...

Minerals such as magnesium, calcium, and phosphorus found in the diet constitute the main structural components of the tooth. Their inadequacy leads to absorption impairment, increased bleeding tendency, bone resorption, looseness, and premature tooth loss. Inadequacy of those essential minerals is associated wi...

Authors: DENTAL SUPPLEMENT, Mummolo S, Sapio S, Falco A, Vittorini OL, Quinzi V Abstract The aim of this study is to evaluate the success of functional rehabilitation of one dental session in patients with severe disabilities such as severe autism, baby bottle syndrome and severe odontophobia, and to assess how patient compliance pre- and post-intervention changes in moderate sedation. Between the beginning of 2016 and the end of 2018, 20 pedodontic patients with severe odontophobia, severe autism and baby bottle syndrome who needed dental treatment came to our attention. Patients were aged between 3 and 12 years, ...
