Clinical Trial Summary
The aim of the present study was to investigate the relationship between the presence of
black tooth stain (BS) and dental caries incidence, dental plaque scores and to examine the
colonization of Streptococcus mutans, Lactobacillus spp., Actinomyces spp. and Capnocytophaga
spp. in dental plaque samples with or without BS. The socioeconomic status of the family, the
oral hygiene and dietary habits of the children, medical and dental history of the children
were also compared between two groups.
Description:
A total of 1000 children aged 3-12 years who applied to the Department of Pedodontics,
Faculty of Dentistry, Ege University for routine dental examination were enrolled the study.
From these group, children with BS (n=44) were selected as the study group. With the same
number of the study group, with the same age and same sex, children without BS (n=44) were
categorized as the control group. The parents were interviewed based on a structured
questionnaire including questions on the socioeconomic status of the family, the oral hygiene
and dietary habits of the children, medical and dental history of the children. The presence
and grading of BS, dental caries incidence and dental plaque index scores were recorded by
the same pediatric dentist (G.İ.). Dental examinations of the children were conducted under
natural light with the aid of a dental mirror and explorer. Dental caries scores were
recorded according to WHO (World Health Organization) criteria using DMFT/DMFS (decay,
missing, filled, tooth/surface in permanent teeth) and dmft/dmfs indices (decay, missing,
filled, tooth/surface in primary teeth). All children were classified according to the
DMFT/dmft scores; Group-1: caries active (dmft+DMFT≥1), Group-2: caries-free (dmft+DMFT=0).
Dental plaque scores were recorded according to Silness & Löe index. The BS scores were
classified according to Gasparetto et al. The plaque samples were dispersed in a vortex mixer
to obtain a homogeneous suspension and cultivated on selective VCAT medium (Oxoid) for
Capnocytophaga spp., mitis salivarius agar (Difco) with 15% sucrose (Difco) and 0.2 units/mL
of bacitracin (Sigma, Sigma-Aldrich Co., St Louis, MO, USA) for S. mutans , MRS Agar was used
for the isolation of lactobacilli spp. (ref) and Actinomyces Selective Agar was used for the
isolation of Actinomyces spp.
All data were analyzed by SPPS 25.0 (SPSS Statistics for Windows, Armonk, NY: IBM Corp.). In
the analysis of data, t test and Mann Whitney-U test were used for the comparison of the two
groups. Categorical data were analyzed by Fisher's Exact Test and chi square test. For the
significance level of the tests, p<0.05 and p<0.01 were accepted.
