Dental caries in children that participated in a dental program providing mother and child care

The main goal of this study was to evaluate the prevalence of caries in children that participate in a dental program attending mothers and children in Teresina, Piauí, Brazil. A selection was made of 343 children of both genders, from 3 to 6 years of age. The mothers answered questionnaires and children were examined at the Infant Dental Clinic of the Federal University of Piauí. The epidemiological index dmft was applied and active white spot lesions were included. The SPSS for Windows program, version 11.1 was used and non-parametric tests carried out (Friedman and Kruskal-Wallis). An alpha error of 5% (0.05) was considered for the null hypothesis of false rejection, with a confidence interval of 95%. The results showed that 57.5% (197) of the children were breast-fed for a period longer than 12 months. The mean dmft index and percentages of caries-free children at the age of 3 was 1.86 (58.82%); at 4 years of age 1.94 (57.60%); at 5 years of age 1.98 (56.86%) and at 6 years of age 2.42 (42.55%). The decay component (d) was prevalent at all ages. When active white spot lesions were added to the dmft index, there was an increase of 7.2% for children who had caries activity and/or previous caries experience and 2.61% for those with dmft equal to zero. The daily consumption of fermentable carbohydrates and free demand breast-feeding were factors increasing caries activity. Dental follow-up after the program and the number of daily brushings were shown to be factors providing protection against caries . Based on the results, the authors were able to conclude that the program caused a positive impact on caries disease control, as the number of dental appointments kept influenced the dmft index values in a statistically significant manner.

Conhecimentos e práticas em saúde bucal de mães que freqüentaram um programa odontológico de atenção materno-infantil

This study assesses the assimilation of knowledge and preventive practices in oral health among the mothers of children assisted by a mother-child dental care program. The Preventive Program for Pregnant Mothers and Babies (PPPMB) is an extension project run by the Piaui Federal University (UFPI), whose goal is to make pregnant women and mothers of children from zero to 36 months old more concerned about habits fostering oral health. After a random selection of clinical record cards for children who had participated in this Program, letters were sent to their mothers. Feedback was received from 281 mothers, who responded through interviews that included questions on matters addressed by the Program. The findings indicate that mothers attending this Program were properly informed, adopting hygienic practices in their families that underpin the control and prevention of oral diseases.

Exploring the association between genetic and environmental factors and molar incisor hypomineralization: evidence from a twin study

BACKGROUND The etiology of molar-incisor hypomineralization (MIH) remains unknown. Studies indicate that it is multifactorial, and that genetic and environmental factors are involved. Research with twins provides important subsidy to investigate the Influence of genetics and environmental factors that act during pregnancy on the etiology of alterations. AIM This cross-sectional study evaluated the agreement of molar incisor hypomineralization (MIH) between monozygotic and dizygotic twin pairs and the association with environmental factors. DESIGN The sample consisted of 167 pairs of twins (8-15 years old), 94 monozygotic and 73 dizygotic. The parents answered a questionnaire on sociodemographic data and pre-, peri-, and postnatal health. A dental examination was performed by two calibrated examiners (Kappa ≥0.88) for MIH diagnosis, following the criteria proposed by the European Academy of Pediatric Dentistry in 2003. RESULTS The prevalence of MIH was 29.3%. There was greater concordance of MIH between monozygotic twins for affected first molars and permanent incisors (P = 0.0012) and pairs of twins assessed (P = 0.0211). The presence of MIH was associated with family income between one and two wages (P = 0.009, prevalence ratio [PR] = 3.82, confidence interval [CI 95%] 1.40-10.44), above two wages (P = 0.007, PR = 4.60, 95% CI: 1.51-14.05), and gestational hemorrhage (P = 0.032, PR = 5.70, 95% CI: 1.16-28.14). CONCLUSIONS The greater concordance in the diagnosis of MIH among monozygotic twins indicates a genetic influence, although environmental factors, such as family income and hemorrhage during pregnancy, are also associated with the occurrence of MIH.

Saúde bucal na estratégia de saúde da família em um colegiado gestor regional do estado do Piauí

Este estudo transversal avaliou o perfil dos cirurgioes-dentistas (CD) que trabalham na Estrategia Saude da Familia (ESF) e a partir deste, refletiu sobre aspectos do desenvolvimento das acoes odontologicas na atencao primaria em saude, de municipios de um colegiado do processo de regionalizacao sanitaria do estado do Piaui, Brasil. O estudo abrangeu os dezenove municipios do referido colegiado. No periodo de agosto a dezembro de 2008, foram aplicados questionarios a 111 CD, que aceitaram participar do estudo e trabalhavam no respectivo territorio. Os dados foram transferidos para o programa Excel®, tabulados e analisados. Os CD avaliados foram predominantemente do genero feminino, com idade entre 20-39 anos, tempo de formado entre um a cinco anos. Eles possuem, em sua maioria, curso de especializacao em area clinica. A maioria faz visitas domiciliares, mas sem a presenca da equipe, com baixa periodicidade e raramente reune-se com esta. Os resultados apontam problemas que provavelmente sao encontrados em outras realidades do territorio nacional. A tendencia do CD a nao interdisciplinaridade e questao ainda em aberto, quando examinado o papel da odontologia e sua potencialmente inquestionavel participacao na estrategia saude da familia.

Vigilância epidemiológica da fluorose dentária em município de clima tropical com água de abastecimento público fluoretada

The scope of this study was to evaluate the prevalence and severity of dental fluorosis among 11 to 14-year-old schoolchildren in Teresina, Piauí, Brazil, which is a tropical city with a fluoridated public drinking water supply. It involved a cross-sectional observational study on a sample of 571 students in public and private schools. Informed Consent forms were approved for the data collection and the exams were conducted at the schools. Data were recorded on a questionnaire answered by the parents, regarding the socioeconomic and demographic characteristics and oral hygiene habits of the sample. The dental exam was performed qualified dental sugeons. The Thylstrup-Fejerskov (TF) index was used. The prevalence of fluorosis was 77.9%, and only 12.5% of the affected children had TF ≥ grade 3 (with aesthetic damage). The premolars were the teeth most affected by fluorosis. Among the students with the highest severity of fluorosis, 98.6% belonged to the lowest social bracket (> B2), 91.5% were born and had always lived in Teresina, 94.4% consumed water from the fluoridated public supply, 76% used toothpaste for children and 64% of mothers reported that they swallowed toothpaste. The prevalence of fluorosis was high, though the severity was low in individuals exposed to fluoridation since birth.The scope of this study was to evaluate the prevalence and severity of dental fluorosis among 11 to 14-year-old schoolchildren in Teresina, Piaui, Brazil, which is a tropical city with a fluoridated public drinking water supply.

Oral health in the family health strategy in a regional management territory of the state of Piaui

The objective of this cross-sectional study was to assess the professional profile of dental-surgeons (DS) who work in the Family Health Strategy (FHS), and on the basis of this reflect upon aspects of the development of dental actions in primary health care in municipalities of a health region of the state of Piauí (Brazil) The study covered the nineteen municipalities of the region. The sample consisted of 111 dentists and data was collected using a questionnaire from August to December 2008. An Excel Ò database was created for the statistical analysis. The dentists were predominantly female, aged 20-39 years, with one to five years of professional experience. Most of them are specialists in a clinical field of dentistry and make home care visits. However, these visits are infrequent and without a health team and they rarely meet with the health team to compare notes. The results indicate that the problems that were detected are likely to be the same in other regions of the country. The lack of an interdisciplinary professional approach among DS is an issue to be properly addressed when examining the role of dentistry and its potentially unquestionable participation in the family health strategy.

Total Fluoride Intake by Children from a Tropical Brazilian City.

The main sources of fluoride intake by children are fluoridated water and toothpaste. Little has been studied regarding fluoride intake from these sources in regions with tropical climates and high temperatures throughout the year. This study aimed to determine the amount of fluoride ingested from diet and tooth brushing by children who live in a city with a tropical climate. Sixty-seven children from Teresina, Piauí, Brazil, took part in this study. The citys water supply was optimally fluoridated. The duplicate-diet method was used to determine the fluoride intake from diet. The intake of fluoride from dentifrice was determined by subtracting the amount of fluoride placed on the toothbrush and that recovered after brushing. The concentration of fluoride was measured using an ion-specific electrode and is expressed as milligrams/kilogram of body weight/day. The mean (±SD) total amount was 0.071 ± 0.036 mg F/kg body weight/day, and the relative contributions of diet and toothpaste were 0.025 ± 0.010 and 0.046 ± 0.035, respectively. The factors associated with fluoride intake from toothpaste were: use of childrens toothpaste (p = 0.003), use of large amounts of toothpaste (p < 0.001), and a high frequency of tooth brushing (p = 0.003). Sixty-four percent of children had an intake of less than 0.07 mg F/kg body weight/day, which is considered the upper limit for an aesthetically tolerable fluorosis risk. The results suggest that the amount of fluoride ingested by most children who live in a Brazilian city with a tropical climate is considered safe in terms of the risk of dental fluorosis.

Homogenous bonding – case report and 18‐year follow up

Fracture of the anterior teeth by trauma is the most frequent type of injury affecting the permanent dentition, especially the maxillary central incisors. When the fragment is not available or its use is not recommended, donated extracted teeth (homogenous bonding) can be used. The aim of this paper is to report the successful 18-year follow up of a maxillary central incisor fracture in which homogenous bonding was performed.
