Dental caries and periodontal disease are the two main diseases initiated in childhood and their prevention should be carried out early before the insidious onset of the disease. Dental plaque is the most important etiologic factor for these diseases. Therefore dental plaque control using various methods and agents helps in controlling initiation of gingival and periodontal diseases. A combinat...

An ion-sensitive field-effect transistor was used to monitor changes in pH following exposure of plaque samples to sucrose. A total of 9O plaque samples were removed from sound enamel, incipient white spot lesions, or cavities of 84 children and placed in a microholder. Sucrose(5% solution) was placed onto the plaque sample and the pH followed for 30 rain by inserting the microelectrode into th...

Background: Dental calculus is a form of hardened dental plaque of both inorganic (mineral) and organic (cellular and extracellular matrix) components. Whereas kidney (renal) calculi is a solid concentration or crystal aggregation formed in the kidneys from dietary minerals present in urine. Aim & Objective: The study aimed to investigate and explore the relationship between dental calculus for...

Dental researchers have attempted to understand the microbial nature of oral diseases over the past 120 years. Their view of plaque and its constituent microorganisms has shifted from a specific plaque hypothesis to a non-specific plaque hypothesis and back again to a theory of specific periodontal pathogens in plaque. Changes in the way plaque and its microorganisms are viewed affect the strat...

A study of dental plaque was first documented in the literature of the 17th century. It has been described as a biofilm composed of bacterial populations living in a plaque matrix. The plaque development starts short time after a tooth surface is cleaned and covered by salivary proteins and glycoproteins conditioning film. Mutans streptococci was described as the most important bacteria related...

background one of the most important factors in inducing the logarithmic growth of streptococcus mutans, is a diet containing fermentable carbohydrates such as sucrose. objectives: the aim of the current research was to compare the ability of ordinary and probiotic chocolate to induce or inhibit the growth of s. mutans. materials and methods lactobacillus rhamnosus, l. plantarum and l. acidophi...

Oral diseases, including dental caries and periodontitis, are among the most prevalent diseases worldwide and develop as a consequence of a microbial dysbiosis. Several bacterial strains are being tested as potential oral health-promoting organisms, but usually they are species isolated from niches other than the site where they must exert its probiotic action, typically from fecal samples. We ...
