[Show abstract][Hide abstract] ABSTRACT: Probiotics has currently attracted for means of preventive treatment measurement instead of using non-specific and broad spectrum antimicrobials. In previous studies, two main probiotics species, Lactobacillus and Bifidobateria, showed the reduction of DMFS and S. mutans counts. However, the timing of introducing probiotic species to oral cavity is not clear. The aim of this study is to evaluate the changes of binding ability of S. mutans in various concentrations and inoculation time of L. rhamnosus GG. Adding the following concentration of L. rhamnosus GG, CFU, CFU and CFU, to S. mutans medium demonstrates significant reduction of S. mutans counts. Additionally, more reduction was observed when L. rhamnosus were inoculated prior to S. mutans or simultaneously inoculated compared to when S. mutans were inoculated prior to L. rhamnosus after 3 hours of incubation. Based on this research, the timing of introducing probiotics should be considered when probiotics are utilized as a preventive treatment measurement.

[Show abstract][Hide abstract] ABSTRACT: INTRODUCTION: The concept of dental caries and its etiologic factors have been raising disagreement in the establishment of preventive strategies among epidemiologists and health professionals. Considerations and knowledge on the formation, progression and definition of carious lesions should be enhanced for establishment of criteria to favor the diagnosis, prevention and treatment, maintaining the life quality of patients. The concept of dental caries as an infectious, transmissible and diet-dependent disease should be revised; the etiologic factors should be better interpreted and understood to avoid mistaken approaches for prevention and treatment. A more conclusive positioning of scientific institutions and universities is required for definitive establishment of these concepts and achievement of practical outcomes. AIM: This study aimed to provide a contribution based on 35 years of professional exercise and academic experience in teaching and research, as well as to conduct a literature review on cariology for interpretation of scientific findings to allow logical conclusions on the concept of dental caries and its etiologic factors, to reach the truth as much as possible. RESULTS AND CONCLUSIONS: The information currently available by means of scientific investigation and also the conclusions of this study allow the formulation of more effective preventive strategies throughout the world allows; in the short term, dental caries will be a minor problem to mankind. Based on the present study, it is concluded that dental caries should not be considered a disease, but rather an enamel lesion due to local causes, without determinant etiologic factors, yet caused by imbalance between physiological factors pertinent to the biodiversity of mankind and specifically to the oral cavity. An objective preventive strategy should aim to achieve biological balance, taking into account the mankind quality of life.

[Show abstract][Hide abstract] ABSTRACT: Saliva, a thick, colorless, fluid that is constantly present in the humans mouth. It is composed of water, mucus, proteins, mineral salts, and amylase. As saliva circulates in the mouth cavity it picks up food debris, bacterial cells, and white blood cells. Three major pairs of salivary glands and many smaller glands scattered in the surface tissue of the cheeks, lips, tongue, and palate contribute to the total amount of saliva. Small amounts of saliva are continually being secreted into the mouth, but the presence of food, or even the mere smell or thought of it, will rapidly increase saliva flow. The functions of saliva are numerous. Primarily, it lubricates and moistens the inside of the mouth to help with speech and to change food into a liquid or semisolid mass that can be tasted and swallowed more easily. Saliva helps to control the body's water balance; if water is lacking, the salivary glands become dehydrated, leaving the mouth dry, which causes a sensation of thirst and stimulates the need to drink. Saliva reduces tooth decay and infection by removing food debris, dead cells, bacteria, and white blood cells. It also contains small amounts of the digestive enzyme amylase, which chemically breaks down carbohydrates into simpler compounds. (2).
