The Effect of Dental Plaque Accumulation on Secretory IgA in Saliva
… subjects whether there is a correlation between dental plaque accumulation , parotid and whole secretory IgA (S-IgA) concentrations and minute secretion rates of S-IgA over a six week period. Eighteen healthy, male freshmen dental students were instructed to refrain from oral hygiene care for six …

Clinical Effects of Daily Rotary Electric Toothbrushing on the Presence of Gingivitis and Supragingival Dental Plaque
… for six weeks, gingivitis and supragingival dental plaque were measured by the Loe and Silness Gingival Index and the O'Leary Plaque Index, respectively. Multivariate analysis revealed that the Rota-dent<sup>R</sup> was superior to the conventional toothbrush in reducing dental plaque …

PCR Detection of Streptococcus Mutans and Streptococcus Sobrinus in Dental Plaque Samples from Low, Moderate, and High Caries Risk Children
… and Streptococcus sobrinus with the incidence of dental caries in children as detected by the polymerase chain reaction (PCR).Methods: Subjects between the ages 2 to 16 years of age were used in this study. After the subjects received a dental examination, dental plaque samples were collected by …

The Effects of Quorum Sensing Molecules on Streptococcus mutans Biofilm
… mutans could reduce the formation of dental plaque on teeth, lowering the incidences of caries and periodontitis. This research studied the effects of three QQ molecules (p-coumaric acid, tyrosol, and farnesol) on S. mutans biofilm formation on biotic and abiotic surfaces. This …

Explainable Machine Learning Prediction of Antimicrobial Peptide Targeting Streptococcus mutans
… mutans is mainly recognized for its role in dental caries, yet it is also increasingly recognized as a significant contributor to systemic diseases. When it gains access to the bloodstream during daily oral hygiene or a dental procedure, S. mutans can become a dangerous systemic pathogen. In …
