Descripción
The accumulation of microorganisms in dental plaque is related to the etiology of caries and periodontal disease, with a high prevalence worldwide. The prophylactic measures include the use of chemical agents as NaF and chlorhexidine. Lactic acid bacteria are members of the normal microbiota of the oral cavity being discussed with regard to their beneficial or detrimental effect in this environment. The present study was performed to determine the growth of some species of Lactobacillus at different concentrations of NaF and chlorhexidine. The strains were isolated from both caries-free and caries patients. Their growth parameters were evaluated by the application of the Gompertz model to the experimental data of optical density as a measurement of growth. The degree of inhibition of the growth of all of the lactobacilli studied was different, depending on each particular strain. NaF at 1 mmol·L–1 inhibited between 5% and 46%, at 5 mmol·L–1 between 13% and 65%, and at 20 mmol·L–1 between 57% and 84%. CHX at higher concentrations (197 and 98 mmol·L–1) showed a complete inhibition of some of the strains. The significance of the results was evaluated by the application of a multivariate analysis and also compared with the inhibition of pathogenic Streptococcus mutans and with lactobacilli strains from collection cultures.
L’accumulation de micro-organismes dans la plaque dentaire est reliée à l’apparition des caries et des maladies parodontales, avec une prévalence élevée partout dans le monde. Les mesures préventives englobent l’utilisation d’agents chimiques comme le fluorure de sodium (NaF) et la chlorhexidine (CHX). Les bactéries lactiques font partie de la microflore normale de la cavité orale et ont des effets bénéfiques ou néfastes sur cet environnement. La présente étude a été accomplie afin de déterminer la croissance de certaines espèces de lactobacilles à différentes concentrations de NaF et de CHX. Les souches ont été isolées de patients avec ou sans caries. Leurs paramètres de croissance ont été évalués en appliquant le modèle de Gompertz aux données expérimentales de densité optique (D.O.) afin d’obtenir une mesure de la croissance. Le niveau d’inhibition de la croissance des lactobacilles étudiées différait selon la souche. 1 mmol·L–1 de NaF a inhibé entre 5 % et 46 %, entre 13 % et 65 % pour 5 mmol·L–1 et entre 57 % et 84 % pour 20 mmol·L–1. Des concentrations élevées de CHX (197 et 98 mmol·L–1) ont complètement inhibé certaines souches. La signification des résultats a été évaluée par une analyse multivariable de même que par la comparaison avec l’inhibition de Streptococcus mutans pathogènes et de souches de lactobacilles issues de cultures de collections.
