Visual Inspection and Toothbrush Care: A Mother-Baby Paired Cross-Sectional Study

ABSTRACT Objective To evaluate the physical conditions and presence of residues of toothbrushes used by mothers and their babies and mothers' knowledge about toothbrush care. Material and Methods This was a cross-sectional study comprising a convenience sample represented by 60 mother-baby pairs. The mothers answered a questionnaire to evaluate their knowledge of toothbrush care. A calibrated dentist performed a visual inspection of the toothbrushes. Statistical analysis was performed using the chi-square and Fisher's exact tests, with a significance level of 5%. Results It was found that 82% of the mothers had never received instructions regarding the care of toothbrushes after use (p=0.024). Most of them believed that their toothbrushes (70%) and their children's toothbrushes (88%) were in good condition to use (p=0.043). However, most mother's toothbrushes presented an unacceptable deformity of the bristles (65%) and the presence of residues (60%). In addition, babies' toothbrushes also presented unacceptable deformities of the bristles (52%) and residues (55%). There was an association between the lack of instructions received by the mother and the presence of deformity and residues on the mother's toothbrush bristles (p=0.037 and p=0.003, respectively). Conclusion Most mothers had never received instructions regarding toothbrush care, which is reflected in the condition of their and their baby's toothbrushes, which presented unacceptable physical conditions concerning deformation and presence of residues.

Daily Toothbrushing Frequency and the Association with Parental Report of Dental Pain and Discomfort in Preschool Children

Abstract Objective: To evaluate the impact of daily toothbrushing frequency on parental reports of dental pain and discomfort in preschoolers. Material and Methods: An observational cross-sectional study was conducted involving 376 children between four and five years of age at public preschools in the city of Campo Magro, Brazil. Parents/guardians answered a socioeconomic questionnaire that contained a single question on the child's daily toothbrushing frequency and the Brazilian version of the Dental Discomfort Questionnaire (DDQ-B). Statistical analysis involved bivariate and multivariate Poisson regression analyses (α=0.05). Results: After the adjustments in the multivariate analysis, the prevalence of dental pain and discomfort was lower among children whose last visit to the dentist was for prevention (PR = 4.42; 95% CI: 1.75- 11.14; p=0.002) and those with a higher daily toothbrushing frequency (PR = 2.13; 95% CI: 1.12-4.05; p=0.021). Conclusion: A lower toothbrushing frequency is associated with parental reports of dental pain and discomfort in preschoolers. Educational and preventive measures that stimulate an increase in daily toothbrushing frequency can contribute to a better oral health status in preschoolers, consequently, less prevalence of dental pain and discomfort.

Caries en primeros molares permanentes y factores asociados a esta en escolares de Acapulco / Caries in permanent first molars and associated factors with its in schoolchildren from Acapulco

Introducción: La caries es una de las enfermedades bucodentales más frecuentes y, por ser las primeras en emerger, los primeros molares permanentes son las piezas más susceptibles a esta afección. Objetivo: Estimar la prevalencia de caries y factores asociados a esta en los primeros molares permanentes en escolares de segundo grado de primaria. Métodos: Estudio transversal, en estudiantes de segundo grado en 17 de 67 escuelas públicas de Acapulco, Guerrero. Un cuestionario autoadministrado se utilizó para obtener datos sociodemográficos y hábitos de higiene dental. La caries y la presencia de placa dentobacteriana se midieron a través de índices epidemiológicos, el CPOD (diente cariado, obturado y perdido) y el O'Leary. Se estimó la razón de momios e intervalo de confianza de 95 por ciento, ajustada por conglomerado, como medida de la fuerza de asociación mediante análisis multivariado. Resultados: Se revisaron 3332 primeros molares permanentes, el 21 por ciento tuvo caries, el 6 por ciento tuvo obturaciones y el 1 por ciento ya se había extraído. El índice CPOD de caries grupal fue 0,27. Cinco factores estuvieron asociados a la caries de los primeros molares permanentes: higiene dental deficiente (RMa = 2,87), técnica de cepillado dental inadecuada (RMa = 1,70), tomar alguna bebida dulce antes de ir a dormir (RMa = 1,68), visitar al dentista (RMa = 0,67) y aplicación de flúor (RMa = 0,61). Conclusiones: La prevalencia de caries en los primeros molares permanentes fue 21 por ciento dentro del rango reportado en otros estudios. Fueron identificados cinco factores asociados a la caries: higiene dental deficiente, técnica de cepillado inadecuado, consumo de azúcares antes de dormir, visitas al dentista y aplicación de flúor. Estos factores orientan sobre qué medidas preventivas se deben promover en los escolares para la preservación de sus piezas dentales(AU)

Introduction: Caries is the most frequent oral disease and the first permanent molars are very susceptible to this condition because they are the first teeth to emerge. Objective: To estimate the prevalence of caries its associated factors in the first permanent molars in second grade primary school children. Methods: A cross-sectional study was carried out in second grade students in 17 out of 67primary public schools in Acapulco, Guerrero. We applied a self-administered questionnaire to obtain sociodemographic data and dental hygiene habits. Caries and the presence of dentobacterial plaque were measured through epidemiological indices, CPOD (decayed, blocked and lost tooth) and O'Leary index. The odds ratio and 95 percent confidence interval, adjusted by cluster, were estimated as a measure of strength of association through multivariate analysis. Results: We reviewed 3 332 permanent first molars, 21 percent had cavities, 6 percent had seals and 1 percent had already been removed. The CPOD index of group caries was 0,27. We found five factors associated with caries of the first permanent molars: deficient dental hygiene (RMa=2,87), inadequate tooth brushing technique (RMa=1,70), drinking a sweet drink before bedtime (RMa=1,68), visiting the dentist (RMa=0,67) and fluoride application (RMa=0,61). Conclusions: Prevalence of caries in the first permanent molars was 21 percent, within the range reported in other studies. Five factors associated with caries were identified: poor dental hygiene, inadequate brushing technique, consumption of sugars before going to sleep, visits to the dentist and application of fluoride. These factors guide what preventive measures should be promoted in schoolchildren for the preservation of their teeth(AU)

La higiene oral y los efectos de la terapia periodontal mecánica / Oral hygiene and effects of mechanical periodontal therapy

Introducción: Las enfermedades periodontales junto con la caries dental son las patologías más frecuentes que afectan los dientes y tejidos circundantes. El principal agente etiológico es el acúmulo de biopelícula dental bacteriana ya sea en las fosas y fisuras de los dientes como en el surco gingival. Objetivo: La presente revisión narrativa tuvo por objetivo sintetizar los resultados de la terapia mecánica sobre la higiene oral al ser indicadas en pacientes con diagnóstico de periodontitis. Material y Métodos: Se realizó un estudio descriptivo que se basó en una revisión crítica de las publicaciones relacionadas a la terapia periodontal mecánica en las bases de datos: Scopus, SciELO (Scientific Electronic Library Online), MEDLINE (Pubmed), ScienceDirect así como el buscador Google académico. En cada base de datos se realizó una búsqueda libre de la información con un límite de 10 años de antigüedad de las fuentes de información para analizar tanto fuentes antiguas como actuales. Resultados: De una búsqueda inicial de 678 artículos se incluyeron 52 estudios que compararon técnicas de higiene oral, así como revisiones sistemáticas que sintetizaron el efecto de la terapia mecánica periodontal. Conclusiones: El tratamiento periodontal debe ser considerado la terapia inicial para la periodontitis, debe incluir instrucción en técnicas de higiene para el control de la biopelícula dental y el debridamiento mecánico de las zonas afectadas. No se ha demostrado que una técnica de cepillado manual específica sea superior a otras, por tanto, se debería aplicar aquella que mejor pueda manejar el paciente. No se encontró evidencia que demuestre que el uso del hilo dental disminuya eficientemente los índices de biopelícula dental y parámetros gingivales debido a la dificultad por parte del paciente para emplear adecuadamente la técnica(AU)

Introduction: Periodontal diseases together with dental caries are the most frequent pathologies affecting the teeth and surrounding tissues. The main etiological agent is the accumulation of bacterial dental biofilm in the pits and fissures of the teeth and the gingival sulcus. Objective: The present narrative review aimed to synthesize the results of mechanical therapy on oral hygiene when it is indicated in patients with the diagnosis of periodontitis. Material and methods: A descriptive study was conducted. It was based on a critical review of some articles related to mechanical periodontal therapy published in databases such as Scopus, SciELO (Scientific Electronic Library Online), PubMed/ MEDLINE and ScienceDirect. Google search engine was also used. A free search for information was carried out in each database. An age limit of 10 years was established for the analysis of both old and current sources. Results: The initial search included 678 articles. Of these, 52 studies that compared oral hygiene techniques as well as systematic reviews that synthesized the effect of mechanical periodontal therapy were included. Conclusions: Periodontal treatment should be considered as the initial therapy for the treatment of periodontitis. It should include oral hygiene instructions for the control of dental biofilm and mechanical debridement of the affected areas. A specific manual brushing technique has not been proven to bebetter than others; therefore, the one that can best be performed by the patient should be used. There was no proven evidence that effective flossing reduces dental biofilm indexes and gingival parameters due to the patient difficulty to adequately perform the technique(AU)

Brush up: an innovative technological aid for parents to keep a check of their childrens oral hygiene behaviour / Brush up: uma ajuda tecnológica inovadora para os pais controlarem o comportamento de higiene bucal de seus filhos

ABSTRACT Objective: To investigate the impact of "Brush Up" - a mobile application, on oral hygiene behaviours of 4-6-year-old children in Bangalore city. Methods: In this experimental study, 247 children aged 4-6, were randomly divided into three groups. Considering "Brush Up" is a mobile application, parents of the children in Group 1 (n=82) downloaded the application on their smartphones. Children in Group 2 (n=83) and Group 3 (n=82) received tooth brushing instructions by an educative video and manual demonstration, respectively. Effectiveness of tooth brushing was assessed with plaque scores, which were recorded for all the groups at baseline and one month using Visible Biofilm Index. Results: Wilcoxon signed rank test showed a significant improvement in the tooth brushing behaviour for the Brush Up group, which was indicated by a lower plaque score after a follow-up of one month. Kruskal-Wallis test followed by post-hoc test showed that the mean ranks of plaque scores of Brush Up group are consistently lower than those of video demonstration group and manual demonstration group. Conclusions: The lower plaque score in subsequent follow-up in Brush Up group suggests that using a smart system can enhance learning a correct tooth brushing method in young children and can also help in implementing the required reinforcement and motivation to brush and aid in better plaque control.

Impact of oral hygiene in patients undergoing mechanical ventilation in the COVID-19 pandemic

SUMMARY COVID-19, caused by SARS-CoV-2, can present respiratory complications that often lead patients to depend on mechanical ventilation (MV) for several days. It is known that Pneumonia Associated with Mechanical Ventilation (PAMV) is frequent in patients who use this equipment for a long time. As a consequence of COVID-19, its prolonged use can lead to a worse prognosis for the patients. For this reason, in addition to the insufficiency of devices for mechanical ventilation to meet the current demand, it is necessary to adopt measures aimed at preventing complications that may aggravate the patient's clinical condition and, consequently, increase the average hospital stay and the respective hospital care costs. Therefore, the objective of this study was to discuss, in a concise and practical way, and based on the available literature, the importance of adopting adequate oral hygiene protocols for patients on mechanical ventilation. Based on the data obtained, it was identified that the adoption of effective oral hygiene measures, especially under the supervision of dental professionals, can contribute to the reduction of morbidity and mortality associated with MV, resulting in greater availability of mechanical ventilation equipment. Since such equipment is in great demand during the COVID-19 pandemic, the knowledge and implementation of effective oral hygiene measures will undoubtedly have an impact on improving the quality of care offered to patients, therefore benefiting all those in critical health conditions and assisted in ICUs.

RESUMO A COVID-19, causada pelo Sars-CoV-2, pode apresentar complicações respiratórias que, muitas vezes, levam o paciente a depender da ventilação mecânica por vários dias. Sabe-se que a Pneumonia Associada à Ventilação Mecânica (PAVM) é frequente nos pacientes que utilizam esse equipamento por um longo período de tempo e que sua ocorrência, consequente à COVID-19, pode cursar com um pior prognóstico para o paciente. Por esse motivo, e somado à insuficiência de aparelhos para atendimento da demanda atual, faz-se necessária a adoção de medidas que visem à prevenção de complicações que possam agravar o quadro clínico do paciente e, consequentemente, aumentar o tempo médio de internação e os respectivos custos da assistência. Sendo assim, o objetivo deste estudo foi discorrer de forma concisa e prática, com base na literatura disponível, sobre a importância da adoção de protocolos adequados de higiene oral nos pacientes em ventilação mecânica. Com base nos dados obtidos, identificou-se que a adoção de medidas efetivas de higiene oral, principalmente sob a supervisão do profissional dentista, pode contribuir para a redução da morbimortalidade associada à PAVM, resultando em maior disponibilidade de equipamentos de ventilação mecânica. Desde que tais equipamentos estão sendo muito demandados durante a pandemia da COVID-19, o conhecimento e a implantação de medidas efetivas de higiene oral, indubitavelmente, repercutirão na melhoria da qualidade da assistência oferecida aos pacientes, portanto, beneficiando todos aqueles em situação crítica de saúde e assistidos em UTIs.

Effectiveness of over-the-counter tooth-whitening strips and toothbrushing for stain removal / Eficácia da utilização de tiras de clareamento dental e da escovação na remoção de manchas dentais

Objective: The present study compared the effectiveness of over-the-counter tooth-whitening strips and too-thbrushing for stain removal. Materials and method: Forty bovine teeth were subjected to initial color re-adings and divided into two groups: 20 teeth were stained with grape juice for seven days and 20 did not receive any treatment (control). Each group was subdivided into two groups (n=10) according to treatment: whitening strips twice/day (30 minutes/7 days) and mechanical brushing with toothpaste (one year). After the treatments, final color readings were taken and color stability (ΔEab), coordinates (ΔL, Δa, Δb), and whitening index (WID) were calculated and analyzed statistically (two-way ANOVA, Bonferroni α=0.05). Results: Statis-tical differences were found for ΔEab and all coordinates between the Control and Stained groups, with major changes in the Stained groups for both treatments. In the Control group, whitening strips produced greater changes in Δb (p <0.05), indicating decrease of yellowness. For the Stained group, whitening strips produced greater changes in Δa (p <0.05), indicating redness reduction. Conclusion: Both treatments were effective for removing stains, and whitening strips were more efficient and effective for changing the color of teeth without previous staining. (AU)

Objetivo: o presente estudo comparou a eficácia das tiras de clareamento dentário e da escovação na remoção de manchas. Materiais e método: quarenta dentes bovinos foram submetidos à lei-tura inicial de cor e divididos em dois grupos: 20 manchados com suco de uva por 7 dias e 20 não receberam tratamento (controle). Cada grupo foi subdividido em 2 grupos (n=10) de acordo com o tratamento: tiras de clareamento 2 vezes/dia (30 minutos/7 dias) e escovação mecânica com cre-me dental (1 ano). Após os tratamentos, leituras finais de cor foram realizadas. Então, a estabili-dade de cor (ΔEab), as coordenadas (ΔL, Δa, Δb) e o índice de clareamento (WID) foram calculados e analisados estatisticamente (two-way ANOVA, Bonferroni α=0,05). Resultados: diferenças es-tatísticas foram encontradas em ΔEab e todas as coordenadas entre os grupos controle e mancha-dos, com maior alteração no grupo manchado, independente do tratamento. No grupo controle, o clareamento produziu maior alteração em Δb (p <0,05), indicando redução do croma amarelo. Nos dentes manchados, ocorreu maior alteração em Δa nos dentes clareados (p <0,05), indicando diminuição do croma vermelho. Conclusão: am-bos os tratamentos foram eficazes na remoção de manchas e o clareamento dentário mostrou-se um método mais eficiente e efetivo para alteração de cor de dentes que não haviam sido submetidos à pigmentação prévia.

Efficacy of Two Different Toothbrushes on Plaque Control: A Randomized Clinical Study

Objective: This parallel, randomized, examiner-blind clinical trial aimed to evaluate the efficacy of two different toothbrushes (manual and sonic) on plaque control in adolescents. Material and Methods: This study enrolled 56 volunteers, randomly allocated to two different groups: group A (n = 28) for the manual toothbrush (Curaprox 5460 Ultra Soft®) and group B (n = 28) for the sonic toothbrush (Edel White®). Mean age was 17.2 ± 1.1 years. A calibrated periodontist performed a periodontal evaluation to assess the presence of plaque with the Turesky Modification of the Quigley Hein Plaque Index (PI) and the gingival inflammation with the Silness & Löe Gingival Index (GI). Adolescents received instructions about the mechanical control of plaque at baseline (T0), with a reexamination after 3 months (T1) and 6 months (T2). Non-parametric Mann Whitney test was used to compare the differences between the two toothbrush groups and the Friedman test was used for the comparisons between times. Results: There has been PI reduction concerning the study times (T0, T1 and T2, p<0.05), but not between the groups A and B (p>0.05). As for GI there has been no significant difference between the groups and between the study times (p>0.05). Conclusion: Both toothbrushes were efficient in the control of supragingival plaque (visible biofilm).

An in Vitro Effectiveness Evaluation of Chemical Agents for Toothbrushes Disinfection

Objective: To evaluate in the vitro effectiveness of three chemical agents for toothbrush disinfection. Material and Methods: Sixteen new toothbrushes were evaluated, previously sterilized and classified in five experimental groups (n=3) and one item as control. Three chemical agents were assessed: 0.12% Chlorhexidine gluconate (CHX), essential oil mouth rinse (Listerine) and 3.5% Sodium hypochlorite (NaOCl). The five selected strains were inoculated on toothbrushes and incubated for a 24 hours period and 37°C temperature in aerobic conditions. The incubated toothbrushes were immersed for a 15 min period into selected chemical agents and after drying in a controlled air stream, again re-cultured into enriched broth. A comparison was made between the initial and final microorganisms density recovered after chemical disinfection based on Mc Farland scale. The data obtained was compared by descriptive analysis and ANOVA methodology. Results: 3.5% NaOCl was the most effective chemical agent for toothbrush disinfection followed by CHX; Listerine was not effective to eliminate the inoculated bacteria in toothbrushes. Conclusion: 3.5% NaOCl and 0.12% CHX are the most effective chemical agents for toothbrush disinfection and Listerine was only effective against C. albicans.

The Effectiveness of the Use of "Special Grip Toothbrushes" on Dental Hygiene for Indonesian Patients with Ischemic Stroke

Objective: To find out the effectiveness of specially made brushes with special grips for use by groups of ischemic stroke sufferers for oral hygiene. Material and Methods: A sample of 30 stroke patients were taken at the Makassar Stroke Center, Indonesia, with criteria for extreme hemisphere ischemic stroke patients and willing to participate in the study and fill out informed consent. Brush making with a special grip design (modified brush) with Clay mixed material. The oral hygiene assessment procedure of the sample using a modified toothbrush was done in 3 stages before the brush, after brush and on the seventh day. Oral and oral hygiene was measured using the index of Oral Hygiene Index Simplified (OHI-S). The oral hygiene assessment procedure was done in 3 stages before the brush, after brush and on the seventh day. To find out the difference in effectiveness before and after the intervention was analyzed using the paired t test. The level of significance was set at 5%. Results: The highest percentage of stroke patients were female (53.3%), aged 40-60 years (66.7%) with an education level below junior high school (56.7%). There is a difference in the average OHIS score before and after using a special grip toothbrush (p<0.01). Conclusion: A special grip toothbrush that is used for Stroke sufferers can help to clean his teeth and mouth.

Evaluation of Tooth Brushing in Slovak Patients with Sclerosis Multiplex

Objective: To analyse issue of teeth brushing according to age, gender and length in Slovak patients with multiple sclerosis disease (MS). Material and Methods: In this descriptive study, the questionnaires were collected in neurologists from December 2016 until September 2017. The study sample consisted of 103 MS patients (44.7% of men) in a mean age of 38.4 ± 9.95 years. The study sample of MS patients was divided into two sub-groups. The first sub-group consisted of MS patients who were restricted in teeth brushing (n=56) and the second group of MS patients, which had no restrictions in teeth brushing (n=47). Descriptive statistics were used to calculate the absolute and relative frequencies, mean and standard deviation. A two-sample ttest was used to compare of the proportion between sub-groups with restrictions and sub-group no restrictions in teeth brushing. The statistically significant level was determined at p<0.05. Results: The significant higher mean age (40.4 ± 10.8 years) was found in MS patients who had restrictions in teeth brushing (p=0.043). Females described often no restrictions in teeth brushing than males (59.6% vs. 40.4%; p<0.05). Length in MS disease (≤3 years) has significant impact on patients in who were not found restrictions in teeth brushing (31.9%; p=0.037). Conclusion: We recommend individual doctor approach to MS patients in older age and using of electric toothbrushes in MS patients who have hand functioning restrictions.

A new technique for tongue brushing and halitosis reduction: the X technique

Abstract The tongue is one of the primary sources of halitosis. The manual or mechanical removal of biofilm is known to decrease oral malodor. Objective: To evaluate a new tongue hygiene technique hereby referred to as "the X technique" and its effects on both halitosis and the number of microorganisms based on microbiological parameters and diagnostic features of the breath. Material and Methods: The study included thirty patients divided into a control group (patients without systematized guidelines of lingual hygiene, but who performed the mechanical cleaning of tongue dorsum, each in its own way), the 3R group (instructed to perform the movements of the X technique for 3 repetitions at each brushing), and the 6R group (instructed to perform 6 repetitions of the technique at each brushing). After two weeks, a new data collection was performed. Results: Patients in the 6R group presented the lowest score on the organoleptic assessment scale at the second consultation, followed by the 3R group and the controls. Regarding the self-perception of breath by the method of Visual Analog Scale (VAS), the control group did not perceive improvements in oral malodor; the results of the 3R group and the 6R group were similar. Conclusion: These results indicate that the X technique improves both measurements and perceptions of halitosis. Microbiological analyses revealed greatest reduction in the 6R group. The findings show that the X technique reduces both organoleptic scores and the number of bacterial colonies, and improves users' perceptions of their breath.

Whitening toothpaste containing activated charcoal, blue covarine, hydrogen peroxide or microbeads: which one is the most effective?

Abstract The efficacy of whitening toothpastes is questionable and controversial. Clinicians, patients and researchers have expressed concern with whitening toothpastes due to the risk of wearing the dental structure and the potential for disappointment if the advertised cosmetic results are not achieved. Objective: This study compared the whitening performance of toothpastes with different whitening technologies after initial and continued use. Material and Methods: Ninety bovine incisors were stained using a concentrated solution of black tea. They were randomly distributed into 6 groups, according to the toothpaste whitening technology: activated charcoal (B&W), blue covarine (WAD), hydrogen peroxide (LWA), microbeads (Oral B 3D White Perfection - 3DW) and optimized abrasives (XW4D). They were compared to a traditional toothpaste without a whitening agent (TA - control). Specimens underwent a brushing machine with controlled pressure, time and temperature. A calibrated examiner measured the color using a VITA-Classical scale before the first brushing cycle (T0), after the first brushing cycle (TI), and after a brushing cycle that simulates continuous use (TCU). Whitening performance was evaluated by the difference of shades (ΔSGU) between T0-TI and T0-TCU timepoints, using the Kruskal-Wallis and Dunn's non-parametric test. The Wilcoxon test was used to evaluate the cumulative effect (α=0.05). Results: Statistically significant differences were observed between toothpastes in both TI and TCU (p<0.05). The time of use also had a significant effect (p<0.05). Conclusion: Only WAD and 3DW showed whitening performance after the first use (TI). The greatest whitening performance after continuous use was obtained by WAD, followed by LWA and 3DW. The use of conventional toothpaste (TA) promotes no tooth whitening. Clinical relevance: Microbead abrasives (3DW) and blue covarine (WAD) were the active technology tested that presented the best global tooth whitening performance.

Efficacy of Sealing with Glass Ionomer Cement and Transversal Brushing Technique in Erupting First Molars: 18-Month Clinical Follow-Up

Objective: To verify the effectiveness of sealing with glass ionomer cement and transversal brushing in the prevention and treatment of initial caries lesions in erupting permanent molars of children aged 5-7 years. Material and Methods: Healthy teeth with ICDAS scores 1 or 2 were selected. One hundred and thirty-one children (79 teeth in the control group - 75 teeth in the test group) were randomly assigned into the two experimental groups: (1) transversal brushing technique for plaque control with conventional flat bristles and fluoridated dentifrice or (2) sealing the occlusal surfaces with glass ionomer cement (Vitro Molar®). Follow-up was performed for 18 months and the survival analysis was applied to test the occurrence of lesion progression. Results: The mean age of children was 5.4 years and it was verified that, by examining the initial tooth condition, the probability of progression was 66% lower when the tooth had initial caries lesions than when it was healthy; the probability of molar progression was about 74% lower in the test group compared to the control group. The mean time for lesion development in the test group (16.8 months; SD = 0.5) was greater than that in the control group (16.5 months; SD = 0.5; p=0.008). Conclusion: Sealing reduces the progression of caries disease in initial lesions when compared to the transversal brushing technique.

Is the fluoride intake by diet and toothpaste in children living in tropical semi-arid city safe?

Abstract: Data about total fluoride intake in children living in a tropical semi-arid climate city is scarce, thus we conducted this study. Fifty-eight children aged two to five years, living in a Brazilian tropical city with optimally fluoridated water were selected. Dietary samples were collected using the duplicate diet method on two non-consecutive days in the children's home toothpaste was determined by subtracting the amount of fluoride recovered after brushing from the amount placed on the toothbrush. The mean total dose (SD) of fluoride intake was 0.043(0.016) mg F·kg-1·d-1, with the major (60.6%) contribution from water. The factors associated with the ingestion of fluoride from toothpaste were fluoride concentration of the toothpaste (p = 0.03) and the use of kids toothpaste (p = 0.02). The findings suggest that children have a low fluoride intake, measured by at-home meals and use of fluoride toothpaste; drinking water is the main source of fluoride ingestion.
