No. of bitstreams: 0 Previous issue date: 2009-02-01 Dental fluorosis is a developmental disturbance of dental enamel, caused by successive exposures to high concentrations of fluoride during tooth development, leading to enamel with lower mineral content and increased porosity. The severity of dental flu…
Caries and dental fluorosis in a western Saharan population of refugee children
2008
The aim of this study was to investigate the relationship between dental fluorosis and dental caries among western Saharan refugee children. The western Saharan child population is characterized by adverse living conditions, an unbalanced diet, poor oral hygiene habits, and a concentration of fluoride in the drinking water of around 2 p.p.m. (2 mg l(-1)). A sample consisting of 360 children, 6-7 yr of age, and 212 children, 11-13 yr of age, was obtained from four refugee camps (Smara, Awsard, El-Aaiun, and 27-February) situated in the vicinity of Tindouf (southern Algeria). The children were examined using the World Health Organization criteria for caries diagnosis and Dean's index for fluo…
Oral health in 6-year-old schoolchildren from Berisso, Argentina : falling far short of WHO goals
2010
Objectives: Dental diseases in children have been reduced in recent decades in developed countries, although trends remain unclear in other countries. Oral healthcare in Argentina is based on demand and depends on a patient's health insurance coverage. The objective of this study was to determine the oral health situation of the population of six-year-olds in Berisso, Buenos Aires province (Argentina). Study design: A cross-sectional observational study was performed on schoolchildren from public and private schools. The following factors were evaluated: DMFT, DMFS, dft, dfs, significant caries (SiC), filled, decayed and missing teeth, and the prevalence of caries in both primary and perman…
Prenatal effects by exposing to amoxicillin on dental enamel in Wistar rats
2012
Amoxicillin is an antibiotic widely prescribed; its most frequent side effects are gastrointestinal disorders and hypersensitivity reactions. Over the last 10 years studies have been published which suggest that amoxicillin may cause dental alterations similar to dental fluorosis. Never the less, the results are not conclusive, this is why it was planned the need to make controlled studies on test animals. Objectives: The purpose of this study was to determine the effect produced by amoxicillin prenatal administration on dental enamel in Wistar rats. Study Design: 12 pregnant adult rats were used distributed into five different groups: witness control (n=2) didn't get any treatment; negativ…
Agua de bebida en el lactante
2004
Se revisan tipos de aguas de consumo público y aguas de bebida envasadas. Se realizan recomendaciones sobre las características que debe reunir el agua destinada al lactante. Para la reconstitución correcta de todas las fórmulas de inicio comercializadas en España, el contenido en sodio debe ser menor de 25 mg/l. El agua de consumo público debe hervirse un máximo de 1 min (a nivel del mar) para evitar la excesiva concentración de sales. No precisa de ebullición el agua de bebida envasada. El nivel de flúor debe ser menor de 0,3 mg/l en el primer año de vida para evitar fluorosis. La concentración de nitratos en agua debe ser menor de 25 mg/l para evitar metahemoglobinemia. Aguas con una con…
Evaluation of a fluorosis prevention educational program: A randomized field trial.
2017
Background A 2-group randomized field trial was conducted to evaluate the impact of a fluorosis educational preventive program in mother´s knowledge and practices, and on the urine fluoride concentration of their preschool children. Material and Methods A group of 139 mother-child pairs participated in the study. Randomly, children were assigned to an intervention group, their mothers were participants of an educational program, or a control group (CG); including 69 and 70 child-mother pairs, respectively, the follow-up period was six months. Mother´s knowledge and practices were evaluated and children´s first urine sample was used to measure fluoride concentration at the beginning of the s…
No findings of dental defects in children treated with minocycline
2004
Thanks to their broad antimicrobial spectrum, tetracyclines were found to be valuable for the treatment of many infections (10). Unfortunately, they irreversibly bind to calcifying tissues and are deposited along the incremental lines of dentine and enamel, causing defects and staining, from bright yellow to dark brown (3, 5, 8). According to the American Academy of Pediatrics, tetracyclines are not indicated for the treatment of common infections in children younger than 8 years of age. However, doxycycline (a tetracycline analogue) is recommended for treatment of Rocky Mountain spotted fever in children of any age (1). Minocycline has several advantages over other tetracyclines: it is bet…
Community water fluoridation and caries prevention: a critical review.
2006
The aim of this paper was to critically review the current role of community water fluoridation in preventing dental caries. Original articles and reviews published in English language from January 2001 to June 2006 were selected through MEDLINE database. Other sources were taken from the references of the selected papers. For the past 50 years community water fluoridation has been considered the milestone of caries prevention and as one of the major public health measures of the 20th century. However, it is now accepted that the primary cariostatic action of fluoride occurs after tooth eruption. Moreover, the caries reduction directly attributable to water fluoridation have declined in the…
Factors associated with dental fluorosis in three zones of Ecuador
2019
Background To determine the prevalence of dental fluorosis in 10-12 year-old school children, in three provinces of the inter-andean Region of Ecuador: Imbabura, Pichincha and Chimborazo, as well as the relationship between certain factors, considering that the latest studies go back to the year 2009. Material and methods A cross-sectional and observational study was proposed. A sample of 599 was calculated at 95% of confidence considering population projections for children between 10 and 12 old of three zones of Ecuador. However, 608 school children, who had the acceptance and informed consent of their parents to participate, completed a survey about factors associated with dental fluoros…
