“…These findings are in contrast with other studies, in which Actinomyces spp. were the most prevalent species [28]. The most recent PCR study confirmed that Actinomyces naeslundii is more prevalent in BS patients.…”

Black stain is characterized as a dark line or an incomplete coalescence of dark dots localized on the cervical third of the tooth. Over the last century, the etiology of black stain has been the subject of much debate. Most of the studies concerning this issue were conducted in pediatric population. According to the reviewed articles published between 2001 and 2014, the prevalence of black stain varies from 2.4% to 18% with equal sex distribution. The majority of the authors confirm the correlation between the presence of black stain and lower caries experience. The microflora of this deposit is dominated by Actinomyces spp. and has lower cariogenic potential than nondiscolored dental plaque. Iron/copper and sulfur complexes are thought to be responsible for the dark color. In patients with black stain saliva has higher calcium concentrations and higher buffering capacity. Factors such as dietary habits, socioeconomic status, and iron supplementation may be contributing to the formation of black stain.

“…Several studies showed that there is a positive correlation between high surface roughness and discoloration of denture resins, which is explained by the large surface with various predilection sites for agglomerating colorants [23,24|. Combined with bacterial adhesion and transformation of biofilm this cannot only result in development of caries and periodontal disease but also in further discoloration caused by metabolic products of bacteria [25,26]. Therefore, effective cleaning methods are required.…”

“…Garan et al 43 found that salivary pH was not signifi cantly different between the groups with and without black stains. Costa et al 44 and Li et al 40 report on a similar prevalence of S. mutans in dental biofi lms of patients with and without black stain. Th e presence of black stain has been reported to be associated with a low frequency of caries, but the reasons are still unknown 23 .…”

SUMMARY -Th e aim of the study was to show whether there is any infl uence of food, drink or drug intake on the formation of tooth discoloration. A total of 500 patients aged 15-25 years were examined to take part in the study. Of these, 60 patients were selected and divided into two groups of 30 patients each. Group 1 included patients with black pigmentation on vestibular/oral tooth surfaces. Group 2 included patients without discoloration (control). Data were recorded in a questionnaire. Atomic absorption spectrometry was used to determine elements in discoloration samples. Th e Caries Risk Test (CRT) buff er was used to assess buff er capacity of saliva, while CRT bacteria were used to determine the presence of Streptococcus mutans and Lactobacillus spp. Statistically signifi cant betweengroup diff erences were found for the intake of collard greens and beets (p<0.05), but not for other vegetables. As for drink consumption, patients with pigmentation reported less wine intake (p<0.05) than those without pigmentation. Th ere was no diff erence according to drug intake between patients with and without pigmentation. Patients with pigmentation were older, smoked and had lower saliva pH with lower presence of Streptococcus mutans than those without pigmentation (p<0.05). In tooth discoloration samples, there were traces of calcium, magnesium, iron, copper and zinc. Th e appearance of tooth discoloration is infl uenced by many factors, among which diet and saliva seem to be very important. Our study showed that patients with black pigmentation used to take more beets, while patients without pigmentation were taking more collard greens and red wine.
