“…7,8 These microorganisms may multiply not only from the oral cavity, but also from the environment where the toothbrushes are stored. 1,9 Modern dentistry strongly emphasizes prevention and biosecurity regarding how toothbrushes should be appropriately stored, disinfected and changed at regular intervals. Nevertheless, studies have investigated the microbial contamination of toothbrush bristles after use and the most effective disinfection methods.…”

Purpose:The objective was to determine the effectiveness of antimicrobial solutions on Streptococcus mutans in used tooth brushes.Methods: Sixty children used their toothbrushes twice a day, for seven consecutive days. The toothbrush bristles were then immersed into antimicrobial solutions for 12 hours: Group I-3% neem; group II-5% turmeric; group III-0.5% cetylpyridinium chloride, group IV-0.2% chlorhexidine gluconate. They were then placed into test tubes containing the resultant suspensions were three-fold diluted. Aliquots of 0.1 ml were plated in Mitis Salivarius Agar (enriched with sucrose) using dilution and plating method. Incubation was done in an anaerobic jar for 72 hours at 37°C. Results:The results obtained showed that there was 88% reduction in the Streptococcus mutans in the 3% neem group, 86% reduction in the Streptococcus mutans in the 0.5% cetylpyridinium chloride group,78% reduction in the Streptococcus mutans in the 5% turmeric group, 65% reduction in the Streptococcus mutans in the 0.2% chlorhexidine gluconate group. The difference between them was found to be statistically significant (p < 0.001). Conclusion:Bacterial contamination of toothbrushes was a major cause of concern. All the antimicrobial solutions used in this study proved to be effective toothbrush decontaminants. The efficacy of 3% neem was highest in our study followed by 0.5% cetylpyridinium chloride, 5% turmeric and 0.2% chlorhexidine gluconate.

Efecto del triclosán sobre el biofilm del cepillo dentalObando GA, Torres KE. Efecto del triclosán sobre el biofilm del cepillo dental. Rev Estomatol Herediana. 2007; 17(1):25-28. RESUMENSe evaluó el efecto antimicrobiano de dos dentífricos sobre la flora aeróbica del cepillo dental en uso. El estudio se realizo con treinta individuos entre los 20 y 30 años de edad que se cepillaron los dientes con un cepillo estándar. Quince usaron un dentífrico con triclosán y los restantes un dentífrico sin triclosán. Después de tres semanas se procesaron los cepillos y se obtuvo como resultado que el dentífrico con triclosán posee mayor efecto antimicrobiano sobre el biofilm del cepillo dental que el dentífrico sin triclosán. Palabras clave: DISPOSITIVOS PARA EL AUTOCUIDADO BUCAL / DENTÍFRICOS / BIOFILMES / TRICLOSÁN.Effect of triclosán dentifrice on biofilm from toothbrush ABSTRACT The present study assessed the antimicrobial effect of two commercial dentifrices against aerobic microflora in used standard toothbrushes. The study was carried out on 30 healthy people ranging between 20 and 30 years of age. Fifteen used a dentifrice without triclosan, and the other fifteen a dentifrice containing triclosan. After 3 weeks the toothbrushes were microbiologically processed. The results of this study demonstrated that the dentifrice with triclosan has greater effect against toothbrush biofilm than the dentifrice without triclosan.

ResumoObjetivo: Este trabalho consistiu em um estudo in vivo para avaliar microbiologicamente a efetividade de uma escova antibacteriana comparada à de uma escova convencional. Metodologia: Trinta crianças de dez a 12 anos utilizaram escovas dentais convencionais e antibacterianas por dois períodos experimentais de cinco dias, com duas escovações diárias supervisionadas, sem dentifrício. O desenho do estudo foi cruzado com wash-out de nove dias entre as diferentes escovas. Ao término de cada período, as escovas foram imediatamente imersas em solução salina estéril e agitadas; o caldo produzido foi semeado em ágar BHI, nas concentrações de 10 -² e 10 -³. Após um período de incubação de 24 horas a 37 °C em aerobiose, foi realizada a contagem das unidades formadoras de colônias (UFC/mL) por meio de um software específico. Resultado: No grupo de escovas convencionais, a mediana e intervalos interquartis foi de 105 (27-564,5); já para o grupo de escovas antibacterianas, foi de 53 (4,5-333,5). Após análise dos dados, observou-se ausência de diferenças estatísticas entre os grupos (p = 0,145). Conclusão: Concluiu-se que as escovas de dentes antibacterianas exibiram contaminação bacteriana semelhante à das escovas de dentes convencionais.Descritores: Escovação dentária; contaminação; viabilidade microbiana. AbstractObjective: This in vivo study aimed to evaluate the effectiveness of antibacterial toothbrushes compared to conventional toothbrushes in reducing microorganisms contamination. Methodology: Thirty children, 10 to 12 years-old, brushed their teeth with conventional and antibacterial toothbrushes two times a day without toothpaste, during two experimental periods of 5 days. The research was designed as a cross-over study with a wash-out period of nine days between the different toothbrushes. After each trial period, the brushes were immediately immersed in individual flasks containing sterile saline solution. After agitation, the solution was seeded on plates containing the culture medium of Brain Heart Infusion, at concentrations of 10 -2 e 10 -3 , to obtain total viable microorganisms. The plates were incubated for 24 hours at 37 °C under aerobiosis and colony-forming units were counted by means of a specific software. Result: In conventional toothbrushes group, median and interquartile values were 105 (27-564.5), while for the group of antibacterial toothbrushes were 53 (4.5-333.5). After analyzing the data, we observed no statistical differences between groups (p = 0.145). Conclusion: It was concluded that the antibacterial toothbrushes exhibited bacterial contamination similar to conventional toothbrushes.Descriptors: Toothbrushing; contamination; microbial viability. INTRODUÇÃOA cavidade bucal é um portal para inoculação de microrganismos em virtude da alimentação e da fala, e do contato com objetos, além de abrigar uma grande quantidade de microrganismos, alguns dos quais, em certo momento, podem se tornar potencialmente patogênicos 1 . A higienização da cavidade bucal evita a ocorrência de patologias, co...
