Candida species is the most frequent fungus found in the oral
cavity [1]. This microorganism provokes a pathology known as
candidiasis in many forms [2], however, this yeast can be found in
dental decay lesions, gingival and periodontal disease [3]. Candida
albicans is the most frequent species of microorganism in all these
lesions [4], however, other Candida species as Candida tropicalis, C
glabrata, C. Krusei, C. guillermondii are less present in oral cavity
[5]. Dental caries, is the most frequent lesions over world and its
etiology is eminently microbial, being the Streptococcus mutans
who produce the teeth demineralization and destruction [6]. The
main of this study is to isolate and characterize the Candida species
from dental caries in deciduous teeth.
Fifty children, female and male, from pediatric dentistry of
Universidad Andina del Cusco, between 4 and 6 years old with
dental caries are selected. Before remove and rehabilitate the
dental caries, with a dental spoon excavator it was collected a caries
sample and stored in 0.9% NaCl [7]. After that, the samples were
sonicated and 100 ul aliquot was placed in CHROM Agar Candida
medium (CHRO Magar, Paris, France) and were incubated for 48
hours at 37°C [7]. It followed the CHRO Magar Candida manual
instructions to determine the presence of Candida species.
The Candida species most present in the dental caries in
deciduous teeth were the C. tropicalis. Other species of Candida are
found in less percentages (Table 1).
Candida species is the most fungus found in oral cavity being the
C Albicans the most pathological yeast of the Candida species [4].
This microorganism was found in many oral lesions as candidiasis,
dental caries, gingival and periodontal disease [2,3]. Other Candida
non albicans are founded in less frequency. However, C. tropicalis
and C. glabrata has been described as emerging pathogens in recent
years [8]. In the present study, C. tropicalis was presented in the
most cases of dental caries in deciduous teeth, being this data
corroborated with other studies who the main pathogen is the C.
tropicalis. Most studies, in fact, found that the C. albicans as the mayor pathogen isolated from dental caries [6,9,10]. This difference
of data can be explained by the geographical location of patients
where Candida species can be found in amounts depending on
the geographical area. In this study, other Candida species, can be
found in less amounts. Despite limitations, the data obtained in the
present study demonstrated the high rate of C. Tropicalis in dental
caries in deciduous teeth, however, has not been determined which
factor is involved in the pathogenesis of dental caries produced
by C. tropicalis. It is also important study the oral microbiome in
dental caries to dilucidated the role of Candida species, mainly C.
tropicalis, in the development of dental caries in deciduous teeth.
