“…The possibility of gag reflex was avoided because there was little contact with culture medium and no patient complained of bad taste. Furthermore, it is a non-invasive technique for detecting microorganisms on surfaces, which could be used for monitoring early caries lesions 9,26 and assessing local risk factors for the development of caries lesions.…”

Aim: To correlate the tray technique for isolation and counting of Streptococcus mutans over dental restoration with the toothpick technique. Methods: Forty 18-50-year-old patients of both genders with high cariogenic risk were selected. Inclusion criteria were: occlusal restoration evaluated as alpha, according to the Ryge's criteria (examiner´ Cohen-Kappa 0.8) and 2 years old maximum age. Each patient provided a saliva sample (control group S) and two samples of dental biofilm from amalgam or resin-based composite restorations in the same patient, one obtained with the toothpick technique (group TT), and the other from homologous tooth restoration with the tray technique (group TR). This method involves only a direct impression on the occlusal surfaces by a section of a fluoride tray with trypticase yeast extract cysteine sucrose with bacitracin (TYCSB) agar previously prepared and solidified. The samples were incubated at 37 ºC for 48 h and the colony-forming units (CFU) were counted. The results were statistically analyzed with SPSS software using the linear regression method at 95% confidence level. Results: TR was able to isolate S. mutans, and there was a significant positive correlation (r=0.95) with TT. There was no significant correlation between TR and control group S (r=0.47). Conclusions: TR was able to isolate and count S. mutans from the dental biofilm of dental restorations with a significant correlation with the TT group.

“…In individuals with normal salivary flow rates, the relationship between salivary flow and coronal or root caries remains doubtful. Whilst some studies showed little or no association , low salivary flow rate was indicative for caries in several other studies . Clinical trials on saliva stimulation by chewing sugar‐free gum after meals showed a significant decrease in caries incidence and that the benefit was attributable to stimulating salivary flow rather than to any chewing gum ingredient .…”

As a highly prevalent multifactorial disease, dental caries afflicts a large proportion of the world's population. As teeth are constantly bathed in saliva, the constituents and properties of this oral fluid play an essential role in the occurrence and progression of dental caries. Various inorganic (water and electrolytes) and organic (proteins and peptides) components may protect teeth from dental caries. This occurs via several functions, such as clearance of food debris and sugar, aggregation and elimination of microorganisms, buffering actions to neutralize acid, maintaining supersaturation with respect to tooth mineral, participation in formation of the acquired pellicle and antimicrobial defense. Modest evidence is available on the associations between dental caries and several salivary parameters, including flow rate, buffering capacity and abundance of mutans streptococci. Despite some controversial findings, the main body of the literature supports an elevated caries prevalence and/or incidence among people with a pathologically low saliva flow rate, compromised buffering capacity and early colonization or high titer of mutans streptococci in saliva. The evidence remains weak and/or inconsistent on the association between dental caries and other saliva parameters, such as other possible cariogenic species (Lactobacillus spp., Streptococcus sanguis group, Streptococcus salivarius, Actinomyces spp. and Candida albicans), diversity of saliva microbiomes, inorganic and organic constituents (electrolytes, immunoglobulins, other proteins and peptides) and some functional properties (sugar clearance rate, etc.). The complex interactions between salivary components and functions suggest that saliva has to be considered in its entirety to account for its total effects on teeth.

“…In recent years, photodynamic inactivation (PDI) has been proposed as an alternative treatment for localized bacterial infections in response to the problem of antibiotic resistance. The bactericidal effect of photodynamic treatment (PDT) has been known for a long time [4][5][6][7]. The method consists in illumination of microorganisms treated with nontoxic photosensitizers (PSs) by low-power visible (red, blue, or white) light.…”

In our research, we determine the effect of low-level laser irradiation with nanoparticles on Streptococcus salivarius. Photodynamic killing of periodontopathogenic bacteria may be an alternative to the systemic application of antibacterial drugs used in the treatment of periodontal diseases. The application of photosensitizing nanoparticles and their excitation by visible light of blue spectra enables effective killing of periodontopathogens. This data combined with the results demonstrates that TiO2, AgTiO2 and S/TiO2 can inhibit the proliferation of Streptococcus salivarius due to its high photocatalytic activity, which irreversibly damages the cell walls and membranes.
